This incarnation of Shockwave has the ability to change his body, using this power to assume the guise of Longarm in order to creep up the Autobot ranks and serve Megatron incognito. To further his guise, changing his actual G1 color scheme to a gray pattern, Shockwave provides his Longarm guise with an alt-mode like that of a burly rough terrain crane. His actual alt-mode is heavily based on the tank mode of Transformers Armada's Megatron. Corey Burton reprises the English-accented, David Warner-inspired voice for the character, but when Shockwave is in the disguise of Longarm, he speaks in an American accent. Furthermore, while this Shockwave's voice sounds identical to that of his G1 self, Longarm's voice sounds much younger than Shockwave himself. Corey Burton revealed Shockwave's inclusion in Season 2 arose from a between scenes conversation he had with the production team, regarding how little the original Shockwave actually had to do.
During Autobot training, his double-agent status was almost discovered by Bumblebee. But thanks to Bumblebee believing the spy to be Wasp, Shockwave managed to plant the evidence to have Wasp as his scapegoat. After successfully graduating from training, Longarm is eventually promoted to Prime rank, and made intel commander of Cybertron, allowing him full access to Autobot files, which he passes onto Megatron, who has him ensure Cybertron is left helpless as part of his master plan. In the two-part "A Bridge Too Close" episode, Shockwave informs Megatron that the Autobot who got the highest scores in the Space Bridge aptitude test is Bulkhead, leading Megatron to capture the Autobot. When the rest of the earth Autobots try to rescue Bulkhead, they are captured themselves, and Shockwave appears on a screen to taunt Bumblebee with the truth of his double agent status, and the fact that he had an innocent Autobot (Wasp) imprisoned (this later led to Wasp becoming Waspinator).
After the "A Bridge Too Close" two-parter, he gained a more prominent role in Season 3, and returned in the season three premiere event "Transwarped". Appearing in his Longarm guise, he was waiting for Megatron's arrival until Blurr returned to Cybertron with information regarding Megatron's communications with the double agent. Once aware that no one else on Cybertron knows the truth yet, Shockwave attacks him and manages to use the base's walls to crush him, taking the remains to Cliffjumper for disposal before being contacted by Megatron. When Ultra Magnus planned on making contact with the earth Autobots, Shockwave uses his guise to convince him to have all communication with them relayed through him, to keep his identity a secret, which is further endangered when the council begins to realize there's a spy in their team.
He next appeared in Where is thy Sting?,infuriated that Jazz, Sentinel Prime, Jetfire and Jetstorm were heading to Earth while after Wasp and attempting to get them to turn back, with Ultra Magnus "calming" him to let his group proceed with their mission. Fearing that his cover will be blown and unable to contact Megatron, Shockwave left a message for him that he would take matters into his own hands. At the episode's conclusion, once word of the truth came to Cybertron, Ironhide attempted to take him into prison, only to find the gravely injured Ultra Magnus lying on the floor, as Shockwave nearly assassinated him and stole his hammer before taking his leave into the long abandoned underground passage ways to hide out.
He appeared as the main antagonist in "This is Why I Hate Machines". When Megatron arrived to Cybertron in Omega Supreme, Shockwave began setting up a scheme to acquire the activation codes to Omega Supreme from the original Autobot who possessed them, Arcee. His plans were slowed down when Ratchet and Captain Fanzone arrived on Cybertron and try to protect Arcee from the clutches of Shockwave. Because of this, Shockwave battled Ratchet several times through the episode, utilizing the stolen Magnus Hammer as his primary weapon. After taking care of the Autobot, he encounters his "old boss", Ultra Magnus and attempts to put him out of commission. He would have succeeded if Ratchet had not intervened. Though he lost Magnus' hammer in the fight, Shockwave escapes with Arcee, resuming his natural purple color scheme upon joining Megatron's group officially.
In the third season finale (which also acted as the series' finale), Shockwave kept Arcee in an operating chamber, where he hooked her up to several wires. Once he received news that Megatron was going to make Omega Supreme clones, Shockwave once again used his Longarm disguise in an attempt to trick Arcee into giving Megatron Omega's activation codes, so that the three Omega clones could be brought online. When the attempt failed, Shockwave took the codes forcefully. However, the codes were missing an essential security patch, requiring Shockwave to set up a bypass, leaving Lugnut to control the clones remotely from Omega. Shockwave later encountered Ratchet, Bumblebee, Bulkhead, and Sari, who had come to save Arcee, and engaged Bumblebee and Bulkhead in battle. Bulkead managed to catch him off guard, punching him to the ground and knocking away his cannon. Forgetting his color scheme, Shockwave took on his Longarm guise in a vain and desperate ploy to gain mercy. Bulkhead and Bumblebee were not fooled however and destroyed the cannon. Shockwave makes a final appearance in the show when he gets taken to Cybertron as a prisoner along with Megatron and Lugnut.
- Animated Voyager Shockwave (2008)
- In keeping with his depiction on the show, Shockwave features four distinct modes; his normal robot mode and a shorter, stockier Longarm robot mode, each with its own alternate mode - a Cybertronian tank and crane, respectively. His faction insignia can be flipped between Autobot and Decepticon.
- Animated Voyager Shockwave with Activators Bumblebee (2009)
- This figure is similar to the normal Animated Shockwave except in his season 3 finale color scheme. He is currently exclusive to Target being packed along with Activators Bumblebee. Like his original Animated action figure, this toy can assume the guise of Longarm and his vehicle mode as well. The purple Longarm (robot mode only) made his first appearance in the final episode of season 3. However, while the Longarm toy itself has gold eyes, his eyes still remain traditional Autobot blue in the cartoon.
