Thundercracker is one of the original Decepticon Seekers from the first year of the series. He is a warrior who usually turns into a jet. He sometimes helps form the Sky Reign combiner.

Fictional biography

Generation 1 1984: Contemptuous of anything that cannot fly. Not totally convinced of the Decepticons' cause, but they persuaded him to continue battling Autobots. Flies at speeds up to 1500 mph... produces controlled, deafening sonic booms that can be heard for 200 miles. Equipped with powerful drone rockets and incendiary gun. Doubts about cause sometimes impede effectiveness.

Generation 1 1991: A mean-spirited, ruthless sky jockey who enjoys running his enemies into the ground. Contemptuous of anyone who can't fly. Engages the enemy in high speed dogfights at maximum altitudes then powerdives straight down. Enjoys pulling up at the last second and sending his opponent into a crash landing. Plane equipped with special, duraflex metal construction that bends to accommodate excessive G-forces. Able to fly very fast at low altitudes, skimming across treetops and dodging obstacles with death-defying accuracy. Plane converts to high density, exo-suit battle armour, impervious to most armaments. Also armed with deafening sonic boom blaster.

Titanium: Thundercracker was so named because of his unique sonic abilities. Even at low altitudes and speeds, he is able to force super-compressed air pulses through his engine intakes, giving him a burst of acceleration and generating a focused sonic boom that can shatter reinforced glass and deafen unprotected audio receptors. He is further able to modulate his sonic booms to affect the sensory response processors of enemy targets, causing panic and fear. Recruited to the Decepticon cause by Megatron himself and assigned to the elite Seeker squadron under Starscream, Thundercracker proved himself to be a deadly and effective warrior, both on Cybertron and Earth. Working alongside fellow Seeker Skywarp, he attacked and destroyed the Autobot stronghold at Altihex, and nearly succeeded in destroying Protihex as well.

Timelines: After being brought back on line by Megatron, Thundercracker just could not fathom serving alongside Starscream, the Decepticon who was the cause of his de-activation. Though he would have been as happy to retire from the war altogether, Thundercracker decided to join Dirge and Thrust under the command of Bludgeon. Despite his utter hatred for Starscream, he often finds himself longing for the days when he was by both Screamer's and Skywarp's side, raining fury down on the Autobots.

Generations: Back on Cybertron, Thundercracker was a master of using sound to his advantage. His fear-inducing sonic booms were tuned perfectly to the compositions of the atmosphere. Sonic vibrations from his attacks could be felt thousands of miles away, generating panic in those nearby, and deep unease even on the other side of the planet.

Animated series

The Transformers

Skywarp and Thundercracker in "More Than Meets The Eye Part 1"

Thundercracker was one of the first Decepticons to awaken on Earth in 1984. After laying dormant for four million years, he shared the same Earthen appearance as Starscream and Skywarp and is usually allied with them during attacks.

Despite being one of the original Decepticons and appearing in many battles during 1984 and 1985, Thundercracker had few prominent roles.

Often chafing under Starscream's self-importance and glory-seeking, he seemed to dislike Starscream and exploited reasons to undermine his authority, such as letting the Autobot Skyfire destroy one of their secret weapons merely so Starscream would get the blame.

Thundercracker appeared in The Transformers: The Movie. In the year 2005, Thundercracker was present during the battle for Autobot City, and was gunned down by Optimus Prime and earlier Kup. With the subsequent defeat of their leader, Megatron, the Decepticons were forced to retreat. However, there were too many Decepticons aboard Astrotrain (who served as an impromptu escape vehicle), and Thundercracker was among those few Decepticons too weakened to put up a fight to stay on board. Being cast out into space, the damaged Decepticons drifted into the path of Unicron, and Thundercracker's body was used to create Scourge, one of Galvatron's new warriors.

In the season 3 episode, Starscream's Ghost, Thundercracker appears to have a grave—or at least a commemorative marker—in the Decepticon crypt.

Transformers Animated

Thundercracker made a cameo in the pilot of the Transformers: Animated series on a historical video being viewed by Optimus Prime. This historical video was stock footage from the original animated series.

Devil's Due Publishing

In this re-imagining of the Transformers: Generation One story, the Autobot ship Ark was discovered by the terrorist Cobra organization. All the Transformers inside were formatted into Cobra vehicles and were to be remotely controlled by the Televipers, Cobra soldiers proficient in communication systems. Thundercraker, who in this continuity, transformed into a Cobra Rattler, was going to be piloted by Major Bludd during an Autobot invasion. Thundercracker had ideas of his own. Changing into robot mode, Bludd is crushed to death inside his cockpit. Thundercracker made no further appearances.

Dreamwave Productions

Thundercracker could always fly, even before joining the Decepticons. He was recruited as a Decepticon under the leadership of Megatron in his war against the Autobots on the planet Cybertron. Thundercracker became a member of the elite Seekers under Aerospace Commander Starscream. He often worked with fellow Seeker Skywarp.

Skywarp and Thundercracker launched an attack against the city of Altihex, where they killed the Autobot named Overhaul and routed Grimlock and his group of Autobots. Later, Starscream, Skywarp and Thundercracker attacked the city of Protihex under the orders of Megatron, but this time Grimlock launched a successful counterattack. If not for Skywarp's ability to teleport to safety, the Decepticons may have not escaped alive. After Megatron's disappearance, Thundercracker remained loyal to the Decepticons.

Because he was part of Megatron's loyal inner circle, Thundercracker was chosen as a member of the crew of the Nemesis when Megatron launched it to attack the Ark, an Autobot ship. Both ships fought, and after the Decepticons boarded the Ark, it crashed on the planet Earth. All on board were placed in emergency stasis lock for millions of years.

In the Earth year 1984, a volcanic explosion awakened the Ark. The Ark's computer, Teletran One, reformatted all on board to be able to assume the forms of Earth machines. Thundercracker, like Starscream and Skywarp, was given the form of an F-15 fighter jet. Eventually the combined forces of the Autobots on Earth, and their human allies were able to capture the Decepticons. A ship called the Ark II was built to take the Cybertonians back to Cybertron, along with some human companions, but the ship exploded shortly after takeoff. The human allies were killed, but the Cybertonians were lost in the ocean, again in stasis lock.

After being awoken again Thundercracker and the other Decepticons on Earth returned to Cybertron with Shockwave, but he later returned to Earth under the command of Starscream. He was captured along with Soundwave and Skywarp by the Autobots and locked in cells on board the Ark. They escaped when the Ark was attacked by Bruticus (Transformers: Generation One III #1).

Fun Publications


In the Fun Publications Classicverse stories Thundercracker is rebuilt on Earth by Megatron to serve as one of his troops. In these stories Thundercracker's appearance is based on the BotCon 2007 exclusive toy.

In the Transformers: Timelines story "Games of Deception" Thundercracker appears among Megatron's troops.

Thundercracker appeared among Megatron's troops in the story At Fight's End by Fun Publications. Thundercracker was repaired and brought back on-line by Megatron. He was apparently willing to put aside his animosity towards Starscream at this point in order to serve under his glorious leader once more. When Megatron staged an attack on Bludgeon, he placed Thundercracker in command of one of the three warships.

Most of the Classicverse universe was destroyed in the BotCon 2012 story Invasion. Thundercracker has not been depicted as one of the survivors and it is unknown if he survives.


Thundercracker gets mentioned in Wreckers Finale Part 2. In the story the Quintessons invade the recently reformatted technorganic Cybertron. Several mechs claiming to be former Decepticons whose sparks were liberated when Optimus Primal reformatted Cybertron live in one of the few technological cites on the planet. These mechs defend the city from the Quintesson Overseer Rexian and his troops. Several of these mechs claim to formerly be the Decepticon warrior Thundercracker, now in a new body. In order to settle their dispute as to which is the real Thundercracker they decide that the one of them that destroys the most Sharkticons can claim the name Thundercracker, and the runner-up can be Dirge.

Wings of Honor

in Battle Lines Thundercracker was among Megatron's troops on ancient Cybertron when Megatron attacked Iacon with his new weapon, Devastator.[5]

IDW Publishing

After Dreamwave's closure, the rights to the Transformers comics were awarded to IDW Publishing. The rebooted Generation One continuity borrowed from many previous sources, included the animated series, as well as the Marvel and Dreamwave comic books, but also featured many new and unexplored ideas and origins. Chronologically, Thundercracker made his first appearance in The Transformers: Megatron Origin, joining the criminal gladiator, Megatron. He, along with his fellow Seekers, played a role in Megatron's plan to cause a rash of terror throughout Cybertron. Thundercracker soon became a member of the Decepticons. Much later, chronologically, in The Transformers: Infiltration, Starscream is in command of a small group of Decepticons on Earth consisting of Skywarp, Thundercracker, Astrotrain, Blitzwing, and the Battlechargers Runabout and Runamuck. Starscream had discovered an Energon ore on Earth that was the Transformer equivalent of steroids, making him bold enough to advance their infiltration phase ahead of schedule. However, humans somehow obtained evidence of the Transformers' existence, derailing Starscream's plans. Thundercracker has so far been seen chasing Ratchet to kill several humans who discovered the Decepticons' presence on Earth. When Megatron finally arrived at the Decepticons' base on Earth to destroy Starscream, Thundercracker was one of the four Decepticons (along with Runabout, Runamuck, and Astrotrain) who stood between Megatron and Starscream—and who promptly surrendered to him without a fight.

Thundercracker reappeared in The Transformers: Escalation, warned by Megatron that no further treachery would be tolerated. Thundercracker then accompanied a repaired Skywarp on a bombing mission to stir up trouble between the humans. Later, he returned to Brasnya with Skywarp after his wingmate had been damaged by Autobots, damaging Hot Rod severely. However, they were forced to flee when Megatron called for pickup after his Ore-13 was expended. His alternate mode here is that of an F-22 Raptor, the successor to his original Generation One F-15 Eagle alternate jet mode.

The 16-part series follows on from Escalation. In the latter half of this series the Seekers' alternate mode once again becomes an F-15 Eagle, and their robot modes resemble their counterparts in the Transformers Masterpiece toy series by Takara.

In the last edition of this series Thundercracker is seen betraying the Decepticons. He saves the North American Eastern Seaboard from a nuclear attack by flying the bomb into space and destroying it. The Autobots are seen rejoicing at Thundercracker's act. Thundercracker did not believe that there was any honor in allowing the humans to die for the sake of it. He believed that a Decepticon was forged by combat, not slaughter. Upon discovery of what he had done, Skywarp shot Thundercracker in the face at point blank range.

Eventually Thundercracker was found by other Decepticons left behind and was rebuilt. None of those left behind were aware of Thundercracker's apparent betrayal, and looked to him to lead them. However, Thundercracker sought solitude instead. For a time he sat alone and watched television, learning about humanity and life on Earth. In time, he came to respect the beauty of life and human culture. While the Autobots went on to seek out other Cybertronians on Earth together with the United States Government, Thundercracker was recruited by Autobot leader Bumblebee to assist in bringing in the Combaticons.

Thundercracker formed the left arm of Sky Reign.

Starscream, Skywarp and Thundercracker Hearts of Steel concept art

Thundercracker and the other Seekers also appeared in the mini-series The Transformers: Evolutions: Hearts of Steel. In this alternate reality tale, Thundercracker served as Starscream's right-hand 'bot. He was presumably destroyed when Bumblebee and John Henry managed to send the entire Decepticon rail convoy into a chasm. Like his fellow Seekers, Thundercracker originally had a beast alternate mode and was later reformatted to an 18th Century flying machine.[6]

1984 Marvel Comics

In the Marvel comics series, Thundercracker was depicted as one of Starscream's lieutenants, along with fellow Seeker Skywarp. (This point was driven home by the fact that while Thundercracker's colors were noticeably different from both Starscream and Skywarp, in the comics he was colored a dark, almost black shade of blue with only the colors of their wing stripes—when drawn in—made the two look different.) Frequently in the early issues, Thundercracker is seen fighting alongside Skywarp, although Thundercracker was shown to be a smarter fighter.

One of the original ten Decepticons that fell to Earth in the Ark. Thundercracker was reactivated and given the Earth mode of an F-15 jet. He would participate in many of the early battles against the Autobots - until a disastrous raid by Megatron led to Thundercracker, along with Starscream, Skywarp, Buzzsaw, Rumble and Frenzy, getting deactivated by Omega Supreme. In the US continuity Thundercracker was eventually rescued along with the other captive Decepticons, by Ratbat's forces, although he returned much earlier in the UK comics, where he was displaced to a limbo dimension by the arrival of future Autobots alongside Frenzy and Shockwave, where they had to work with Optimus Prime, Prowl and Ratchet to survive. He would then participate in the battles against Scorponok's Decepticons and then against the Autobots using their united force. None realised, however, that it was all a ruse by Starscream to gain the power of the Underbase for himself. The Autobots and Decepticons would then unite to stop him, but Starscream's power was too great, and Thundercracker was one of those deactivated by his former wingmate. He was not seen again until the G2 comic, where he seemingly took command of the Decepticon aerial contingent against the forces of Jhiaxus.

According to his expanded Transformer's Universe biography, Thundercracker is unique among his fellow Decepticons in that he has a certain amount of pity for the humans they continually endanger or kill. He does not see the point of killing humans just to kill them as some of his fellows do, although he is very careful not to reveal this. No matter what small amount of sympathy Thundercracker feels for humans, his sense of self-preservation (and fear of what Megatron would do if he found out) outweighs it.

Other appearances

Thundercracker appeared in the Robot Chicken episode "Junk in the Trunk." He was seen with the other Decepticons using a dam to stock-pile energon cubes until the Autobots attacked.


  • Hasbro Transformers Jet Thundercracker (1984)
The original Thundercracker toy was originally part of the Japanese Diaclone toyline, and was imported to become part of the Transformers toyline by Hasbro in 1984.[7] In jet mode, the toy is 21cm long. In what is considered to be a major drawback to the toy, the majority of its parts have to be removed for transformation, and it is rare to find a totally complete one, since no single mode can hold all the parts.[8]
  • Hasbro Transformers Action Master Thundercracker (1991)
A repaint of Action Master Starscream with new accessories, this toy was only released in Europe. The color scheme does not resemble the original. Thundercracker comes with a jet which he can ride or wear as armor when it is transformed. This version of Thundercracker does not appear in any official Transformers fiction. His bio was much the same as the original toy bio, portraying him as a vicious flyer who enjoys taking his enemies apart by causing them to crash - either by shooting them down, or by nosediving and pulling up at the last second, letting his foes slam into the ground.[9]
  • Transformers Machine Wars Thundercracker (1997)
A basic sized flip changer. Sharing the same mold as fellow Decepticon Skywarp, Thundercracker was a "flip-changer" jet where if the toy's nosecone was pressed down, the toy would automatically transform to robot mode. It is difficult to determine where the Machine Wars characters are placed within the overall Transformers storyline as there was no fictional material other than their tech specs. Machine Wars characters are usually considered future or alternate reality versions of the main G1/G2 characters which was never expanded upon.[10]
His tech spec was similar to his original G1 bio in that Thundercracker believed in the Decepticon cause, still possessed of a fierce independent streak. Believing himself superior to anything that cannot fly Thundercracker uses terror-causing tactics and his traditional sonic boom attack to destroy his enemies.
  • Takara Smallest Transformers Thundercracker (2004)
This blue recolor of Smallest Transformers Starscream was only released as a chase item (one in a case of 48) in the line's final wave. Despite the small size (roughly 2 inches in robot height), the toy is virtually faithful to the original G1 toy's design and transformation.[11]: This toy was also released in high numbers by third-party toy makes in a variety of variants, such as metallic, clear and glow-in-the-dark.
  • Takara Robot Masters Thundercracker (2005)
Thundercracker is a repaint of Robot Masters Starscream and was released in a package with Robot Masters Skywarp. Apart from his new chest missiles, he is the exact same character as his original appearance, only with a red stripe in his abdomen and more black in jet mode. Thundercracker did not appear in any Robot Masters fiction.
  • Hasbro Transformers Titanium 6 inch War Within Thundercracker (2006)
A new 6" Thundercracker toy based on his 'The War Within' design. A day later the pictures were taken down at the request of Hasbro. This version of Thundercracker seems to be based on his appearance in the Dreamwave War Within comics series.[12]
This toy was later repainted as a War Within Starscream.
  • Transformers Timelines Games of Deception (2007)
A 5-pack of Decepticon including Deluxe Bugbite, Dirge, Thundercracker and Thrust and Voyager Dreadwind.
Bugbite is a recolor of Classic Deluxe Bumblebee. Dirge is a remold of Classic Ramjet. Thundercracker is a recolor of Classic Starscream and Skywarp. Thrust is a remold of Classic Deluxe Starscream, Skywarp and Ramjet. Dreadwind is a remold and recolor of Classic Voyager Jetfire.
A BotCon 2007 exclusive.
  • Henkei! Henkei! Deluxe Thundercracker (2008)
A blue redeco of Classics Deluxe Starscream by Takara Tomy in Japan, sold as a Toy Hobby Market and Ganbo Store exclusive. The packaging used a black and white picture of the Starscream figure in front and reused Henkei Starscream's card for the back. The paint scheme is close to the original G1 toy, but differs from the Timelines version.[13]
  • Masterpiece MP-07 Thundercracker (2008)
A repaint of Masterpiece Starscream, Masterpiece Thundercracker was released at the end of 2008. Number MP-07 in the Masterpiece series, it is based on his G1-animation deco, albeit designed to look a lot more realistic. A common problem on most, if not all, Masterpiece Thundercracker is that in production the two chest thrusters were switched around. This mistake has no effects on transformation, however.
  • Generations Deluxe Thundercracker (2011)
A recoloration of the Classics Starscream, very similar to the Timelines Thundercracker sold at Botcon 2007.[14]
  • Alternity Mitsuoka Orochi featuring Thundercracker (not yet released)
A recolor of the Alternity Mitsuoka Orochi, which is also used for Starscream and Skywarp.
  • Transformers Masterpiece Thundercracker (2012)

Thundercracker, only mentioned off-screen in Transformers: Armada, finally made his appearance on screen in Transformers: Cybertron. Originally released alone, Thundercracker was later packaged with a Mini-Con partner as a Wal-Mart-exclusive but is unable to powerlinx with the Mini-Con. Although Armada Thundercracker did appear in the Dreamwave comics, he was portrayed very differently from the Cybertron character.

As a character, Thundercracker is a Deception highly distinguished for his love of battle. He speaks with a distinctive southern "drawl" accent. This excessive blood-lust affects the entire Decepticon group. What he lacks in skills, Megatron recognizes Thundercracker's talent for encouraging the troop's fighting spirit. He always has his sights on target in either robot or jet mode. Unfortunately, he cannot concentrate on a target, and accuracy is not his style. He also comes up with special attacks that prove ineffective against his foes, most particularly Jetfire in a battle for sky supremacy, but when reinforcements arrive, he is usually the first to be defeated.

Thundercracker's tech specs by both Hasbro and Takara revealed more about him. The Takara bio noted that he was excessively eager to go into battle, in turn inspiring the Decepticons who fought with him—which is why Megatron keeps him around. His Hasbro bio is indicates that, like the original G1 Thundercracker, his main power is his ability to create deafening sonic booms in combat. Rather oddly, the unlockable content on Hasbro's website indicates he is also somewhat of a practical joker. The non-flying Decepticons often ride on him.

The Wal-Mart-exclusive Mini-Con pack would explain how Thundercracker got his Mini-Con partner Downshift, snatching him from under the Autobot's noses in one of his trademark fear causing missions. What he did not realize was that Downshift was as dedicated to creating chaos as him, and the two formed an alliance to terrorize the Autobots on Earth.

Animated series

Originally appearing as one of the Decepticons under Megatron, Thundercracker was paired with Starscream to search for the Omega Lock on Earth, using his Earthen alternate mode to great advantage.[18] He scanned an aircraft and transforms into the Su-37 and attacked Landmine. He had a rivalry with the Autobot Jetfire over who was the superior flyer. However, he was unaware that his wingmate harbored ambitions of his own. When Starscream gave Megatron a Planet Map to search for the remaining Cyber Planet Keys, the map turned out to be a fake and Thundercracker, along with Megatron, Ransack and Mudflap were trapped in a steel globe until they were freed by Scourge.

In episode #31, "United", Scourge, Mudflap, Crumplezone, Ransack and Thundercracker followed Megatron on the Space Bridge to Cybertron. They were joined by Thunderblast, who claimed she'd rather work form Megatron than Starscream.

Subsequently, Thundercracker was present for many more battles against both the Autobots and Starscream's ancient Decepticons. On one occasion, when Galvatron (a recreated Megatron) needed the Decepticons to distract the Autobots while he used the power of the Cyber Planet Keys to control the Grand Black Hole, he used the power of the keys to turn Dark Crumplezone, Ransack, Thunderblast and Thundercracker into giants, rivaling the size of the Giant Planet Transformers. Thundercracker even took on Optimus Prime himself, but was jumped by Hot Shot and Jetfire, distracting him long enough for Prime to pursue Galvatron. After the fight, the Decepticons returned to normal size.

After Galvatron's defeat and the closing of the black hole, his minions realized that Galvatron had never had any intentions of helping his minions escape the Black Hole disaster in the first place. Thundercracker and the remaining Decepticons abandoned their allegiance to Galvatron and considered themselves free.

When the Autobots attempted to use a gigantic rocket to move the Jungle Planet back into its orbit, Galvatron attacked and damaged the rocket. The Jungle Planet threatened to crash into Cybertron. Much to the Autobots' surprise, the four Decepticons helped Scourge and the Autobots to move the rocket boosters back into place.

After Galvatron's death, Thundercracker, in an attempt to continue being active, allied himself with the Autobots by taking part in construction work on Earth. He wanted to be an Autobot and never lose (even though he did not know how to make the Autobot symbol appear on his body he just put on a badly drawn one). He was forced back to the Decepticon ranks by Thunderblast, Dark Crumplezone and Ransack, who self-declared themselves as the new Decepticon army. Predictably, the hapless group did not get far: the credits montage that closed the series showed they had crashed on what appeared to be Mars.


Dreamwave Productions

Thundercracker's first fictional appearance was in a flashback scene in the Transformers: Energon comic #30 and #31, as one of the Decepticons being led into battle by Scorponok.

While not much was known about Thundercracker, the Dreamwave Productions' More Than Meets the Eye biography series filled in some of the gaps. It reveals that Thundercracker was one of Megatron's elite aerial troops, and was responsible for training Starscream and Skywarp. Eventually he grew disenchanted with Megatron and disappeared. Resurfacing shortly before the battles on Earth, and now with a Mini-Con partner, he seemed to become a mercenary.

Like Starscream, Thundercracker can use one of his wings as an energon blade and is a lethal martial fighter. However, in seeming reference to his original Marvel bio, his only weakness is his self-doubt.

  • Cybertron Deluxe Thundercracker (2005)
The deluxe sized toy of Thundercracker was sold by itself in 2005, as well as packaged with the Mini-Con Downshift and a Tiny-Tin as a promotion at Wal-Mart stores, then again packaged with the Autobot Crosswise as a Target exclusive. The original deluxe sized Thundercracker was recolored into Cybertron Skywarp.[21]
A value 2-pack repackaging Cybertron Excellion and Thundercracker in Transformers: Universe packaging was first seen online in September 2007, called "Opposites Attack".
In 2006, a Target store exclusive 2-pack called the "Ground to Air Blast Pack" included Cybertron Crosswise and Thundercracker. The toys were identical to their original ones, and the front included a brief mention of how the Autobot Bounty Hunter was hunting the Decepticon criminal Thundercracker. His tech spec indicates that his desire to blast Autobots is not out of any sort of sadism—it simply keeps him out of Megatron's way when the Decepticon leader is looking for someone to take his frustration out on.
Cybertron Deluxe Thundercracker is 18 centimeters long, but a real Su-37 Terminator is 2218 centimeters long. This gives us a scale of 1/123. Since his robot mode stands 13.5 centimeters tall, this means Cybertron Thundercracker should stand 54 feet tall. He is not depicted as being this big in the animated series, standing as big as most Deluxe sized toys, a bit over 20 feet tall.
  • Cybertron Legends Thundercracker
Besides his original release as a Deluxe-sized figure, a Micro-class Thundercracker was released in wave 4 of the Legends of Cybertron line. This figure improved on some of the flaws of the Deluxe sized figure, giving Thundercracker a full sized left arm and larger feet that he can better balance on.
This toy was recolored as Classic Legends Jetfire.[22]

Thundercracker's design is also the basis for a series of Decepticon drones.

Fictional biography

Voyager Thundercracker: Thundercracker lives on fear. Special materials in his vehicle body allow him to emit controlled sonic detonations that can be heard 200 miles away. Cruising along at Mach 6, he wants his enemies to hear him before they see him. He wants them to know he's coming, and cower in fear at their impending doom. Not as devoted to the recovery of the Allspark as the other Decepticons, he stays with Megatron because the evil leader allows him to indulge his chaotic tendencies.

Legends Thundercracker: The sky over one of Earth's largest cities erupts into flame as four powerful warriors from another world meet in combat. High in the thin, freezing air of the stratosphere, the ancient warrior Jetfire takes on the Decepticon master of fear in the delicate strategy of a supersonic battle. Meanwhile, in the air just above the tops of the buildings, Autobot Blades and Thundercracker exchange brutal volleys of missile and machine gun fire, each hoping to bring the other crashing down.

Deluxe Thundercracker: Starscream thinks highly of Thundercracker. He tries to instill the less experienced Transformer with attack strategies and weapons information for the day when he finally usurps the throne from Megatron. Thundercracker is a quick learner and a serious threat to any Autobot that dare engage him in battle!


IDW Publishing

In Transformers: Defiance the planet Cybertron is invaded by aliens from the Eshems Nebula and Thundercracker is among the defenders in the city of Metrotitan, near the temple at Simfur. In issue #2 he sides with Megatron in his decision to counter-attack Cybertron's invaders and is among the fleet that attacks their ships. In issue #3 Thundercracker iss among the troops under the command of Starscream ordered by Megatron to bring in Optimus and kill his companions.

Thundercracker also appears in Reign of Starscream comic book series. He is a blue colored Decepticon looking a great deal like Starscream's Cybertronian form. He was left aboard the Nemesis on Mars when the Decepticons attacked Earth in the 2007 movie. Starscream left Earth after and returned to Mars to recreate the Allspark. Thundercacker is loyal to Starscream by helping him recover after his journey to Mars. He addresses Starscream as Lord Starscream, or Commander Starscream. Starscream mentions that Thundercracker is a Seeker, just like himself. Thundercracker seems smart by asking Starscream about Earth, and predicts their vehicles are like their own on Cybertron. In issue #5 Starscream sacrificed the sparks of Crankcase, Elita One, Grindcore, Signal Flare, and Warpath to bring his new Allspark Cube online. Although the cube failed to function Starscream did not have time to find out why as Dreadwing made his bid to overthrow the Decepticons using his army of drones. While Ramjet and Divebomb sided with Dreadwing, Thundercracker remained loyal to his leader along with Stockade. After Starscream vanished through the space bridge, Thundercracker departed Cybertron in hopes of finding him.

In Tales of the Fallen #6 Arcee is taken by Thundercracker and given to the Decepticon medic Flatline, who experiments on her. Upon waking up she discoveres Skids and Mudflap are also captives of the Decepticons.[24]

Thundercracker's appearance in the IDW Publishing comics varies from the toy quite a bit because he never assumes an Earth vehicle alternate mode, instead staying in Cybertronian form. His robot mode more closely resembles the toy for Protoform Starscream in Thundercracker's colors, while his vehicle mode more closely resembles the vehicle mode of Megatron's Cybertronian jet.

Titan Magazines

Thundercracker style drones were seen attacking a NATO fleet in Twilight's Last Gleaming part 2.


Thundercracker also has a small role in the Transformers: The Game video game, most of all on the PSP version, in which one can play as the character in multi-player mode. He speaks a few lines.

Thundercracker is a minion of Shockwave, and spends most of his time transporting the Decepticon from place to place. He also meets Blackout and Shockwave after the Decepticons attack the base in Qatar. Later, he assists Shockwave and Dreadwing to find frozen Decpticon leader Megatron in the Arctic Circle, but they only find information on a launch of a satellite. The Autobots attempt to destroy the base, but Thundercracker and Shockwave escape, leaving Dreadwing dead. He then flies Shockwave to the launch site, and places the signal there awhile Shockwave distracts security. He then rescues Shockwave. After that, Thundercracker alone attempts to stop the Autobots from approaching Hoover Dam, the location of Megatron and the AllSpark, but is killed by Autobot Ironhide. Shockwave does not discover this, but finds that the Autobots have transmitted a virus to the signal, foiling their plot.

In the game, Thundercracker's appearance is based on Dreadwing with a new head, not Starscream.

In Transformers Animated, Thundercracker is a clone of Starscream, and embodies the egomaniacal side of his personality.[27]

Animated series

Using the Allspark fragment embedded in his forehead, Starscream brought life to numerous clones, who took distinct aspects of his personality. Thundercracker received the egomaniac side of Starscream and thus is extremely prideful in his abilities and refuses to acknowledge that he has limits. He participated in the clones' assault on Megatron's stronghold, but was caught up in Mixmaster's cement along with Skywarp and Blurr and ended up being sent through the space bridge, to a unknown destination where Thundercracker managed to break Skywarp and Blurr out of their confinement, only to unsuccessfully attack the latter. Blurr managed to escape, humiliating Thundercracker by using him as a springboard to race his way across the galaxy. Thundercracker's ultimate fate is unknown, as the series ended without him appearing again. He, Skywarp, Swindle, and Team Chaar are the remaining Decepticons in space.

Thundercracker was never called by name in the run of the animated series.

Fictional biography

A founding member of Colonel Deathsaurus' Mayhem Suppression Squad, Thundercracker abandoned his civilian post to oppose the Autobots as a resistance fighter. Jovial and friendly, he is the squad's "morale mechanism". He pities anything that cannot fly, though he uses mango-clamps to take friends flying whether they like it or not. He can create 50-meter wide zones of pure silence but prefers to fight using his cryonic blaster and drone rockets. Recently, during a routine surveillance mission, Thundercracker picked up a signal coming from the prison at Paradron. He couldn't be sure, but could it be that some type of jailbreak was in progress?

Machine Wars Thundercracker is a clone of the original Decepticon created by Jhaixus.

Fictional biography

Thundercracker is loyal to the cause of unifying the Cybertronian Empire, however he does not believe in Jhiaxus' means of doing such. He remains rebellious within the ranks of the new Decepticons and does not fear displaying his contemptuousness to his superiors. Often times Thundercracker prefers taking his clone squadron on monotonous patrols and performing menial tasks so as to distance himself from his fellow Decepticons. This also allows him to practice his latest tactics fro striking fear in his enemies while acting on his disdain for anything incapable of flight, without feeling judgment by the piercing optics of the land bound Soundwave.

Wings of Honor

Thundercracker appears in the Botcon 2013 story Machine Wars: Termination. Thundercracker and his drones responded to an incursion in their territory, but instead found a group of Empties who had wondered from the Rad Zone... or, at least, that's what Thundercracker and his drones thought they were. The Empties revealed themselves to be a rebel cell lead by Obsidian, and consisting of Strika, Hoist, Sandstorm, and Octane. After the rebels quickly blasted the drones into submission, Thundercracker was captured. Strika, Hoist, and Sandstorm interrograted Thundercracker, and eventually got the coordinates to Megaplex's location from him. Thundercracker's capturer's took their time getting outside of Iacon, as they wanted to be seen with him. When Megaplex and his army arrived, Obsidian refused to release Thundercracker, and after Obsidian compared Megaplex to the original Megatron, a battle ensued. [35]
