Doublecrosser is a two headed evil Decepticon who transforms into a ramp/shield to aid other warriors. His ramp mode allows him to join together Decepticon bases, while as a shield, larger robots can use him as a defence.
The siege has ended, and the War for Cybertron has begun! The Autobots and Decepticons have left Cybertron, and their battle rages on as they speed through space in pursuit of the Allspark. Now, fighters must instantly adapt to battle anywhere in the cosmos.
With the highly advanced A.I.R. (Adaptable Interconnection Retrofitter) Locks system, the fighters don’t head to the battlefield — they become it. Bots capable of converting into Modular Battle Stations can A.I.R.-Lock together in custom configurations to fit the needs of battle.
