Airwave was one of the Autobots hidden in Cybertron after the planet fell to Decepticon occupation. The leader of a community of such Autobots, he was known for having poor relations with the Dinobots, considering them dangerous monsters. However, Airwave proved to be the true monster, as his desperation to insure his own survival led him to drain Energon from dead Cybertronians and even commit murder in order to take it from his victims. Eventually the Dinobots discovered his crimes, and working together with the citizens of his city brought him down.
Airwave was one of many Autobots imprisoned by Shockwave. Although he made his escape in the chaos that followed the Dinobots' escape from the Decepticon's facility, what he saw of Grimlock and his men made a bad, bad first impression. As a consequence, he made it clear to Grimlock that his outpost of Last Spark neither desired nor would tolerate any interaction with the Dinobots. After his people started being killed by an unknown predator, however, he grudgingly agreed to Firestar's request to allow Sludge and Snarl to help investigate.
After Sludge, Snarl and Firestar returned to Last Spark to discover that some of the bodies there had been drained of Energon before any attacks were even recorded, they realized the killer must have been someone already living in the town. Airwave, entering the crypt, scoffed at the whole idea...until Sludge suddenly realized the evidence they'd collected pointed at Airwave himself as the killer. Exposed, he struck down Firestar from behind and made his escape in jet mode, rallying the unsuspecting inhabitants of Last Spark to attack the Dinobots by falsely proclaiming them the killers. He then returned to the fight, firing indiscriminately into the crowd. Sludge was able to bring him down from the sky, but the fully-charged Airwave was more than a match for him even on the ground. Airwave declared to the battered Sludge that the planet was dying, that there was no escape, and that the only thing that mattered was who survived the longest. Just before he could deliver the coup de grace, however, he was cut in half by Firestar.
A short time later, Snarl tossed Airwave's carcass on a Last Spark scrap pile.
