Heatwave is a heroic Decepticon loyal to Megatron.
He has the unusual ability to speak to non-sentient machines by touch. Heatwave speaks to machines as if they were living beings. He combines with the other 4 Transformers Collectors Club membership combiner exclusives to form Nexus Prime.
Heatwave appears in Do Over. He volunteers to be a member of the crew of the Decepticon starship Nemesis and Cliffjumper allows him to join. He is on board the Nemesis when it launchs to follow the Autobot's Ark and is among the crew when they eject in escape pods to the planet Earth.
Heatwave is spotlighted in the story The Desert Heat!. In this story, having crashed to Earth in an escape pod, he recovers Soundwave and helps the other Decepticon get back online and assume an Earth-style alternate mode. 
In Eye in the Sky by Heatwave joins up with Ravage. He meets the human scientist Professor Arkeville and his assistants Frederick Ottman, William Hayes, and Josephine Beller. Cliffjumper, Crasher, Frenzy, Heatwave, Ravage and Soundwave are sent on a mission to Burpleson Air Force Base to stop the Autobots from controlling the GODS defense system. Heatwave uses his powers to convince the GODS transmitter to fire the weapon on itself and stop the Autobots from taking control.
In Blitzwing Bop Heatwave and Blitzwing discover the Autobots are building a Stellar Spanner to return to Cybertron. Heatwave is captured and used as a test subject by the Autobots, ending up back on Cybertron, where he is discovered by fellow Decepticons Whisper.
