Deceptitran was once a Fuel Auditor for the Decepticon cause. His gluttony led to him skimming Energon off the top. He got demoted so far down the ranks, he eventually left the Decepticons. During that low, Unicron spoke to him. He offered a deal: help him spread chaos and he can guzzle Energon to his Spark’s content. Deceptitran accepted and became a Terrorcon. He made it to Mobius after Unicron summoned him and, after a failure he was part of, bore witness to the Chaos Bringer’s rise. During the final months of the Year of Unicron, Megatron ambushed him and killed him with the reforged Requiem Blaster, then used his corpse as bait for his other target. He was sent to Hell for his crimes. After rotting there, he was restored to life by the Author’s hand, promising him a sweeter deal than Unicron’s. He’s ready to devour anyone who gets in his way.
