Birdbrain, Slog, Scowl, Wildfly and Icepick (plus an unconscious Sideswipe).
The Pretender Monsters are a team amongst the evil Decepticons. They are composed by Birdbrain, Bristleback, Icepick, Scowl, Slog and Wildfly. They are all Pretenders, Transformers with organic shells that allow them to disguise their mechanical nature and can combine to form the giant robot Monstructor.
Fiction[]
Devil's Due G.I. Joe vs Transformers continuity[]
Some time prior to 1978, in the Himalayan Mountain region of Tibet, Bludgeon led the soon-to-be Pretender Monsters to meet with the underground kingdom of Cobra-La, seeking power and a ringside seat at the death of a planet. En route, they were shot down and damaged by the Chinese Air Force, however, forcing Bludgeon to make a deal with Cobra-La: in exchange for defending Cobra-La's subterranean domain, Cobra-La provided them with life-supporting organic Pretender shells.
At the behest of Golobulus, the Pretender Monsters used their shells to slip past the sensors of the submerged Autobot ship Arc II, where they made quick work of Skids, Sideswipe and Prowl. Black Horizon, Part 1 of 2
Later, when G.I. Joe sent an invasion force against Cobra-La, they merged into Monstructor to repel the invaders. Monstructor wreaked havoc on the Joes but was defeated when the laser squad blew up his head, leaving his component members in an unconscious heap. Black Horizon, Part 2 of 2
