Bio[]
One of the most instinctive strategists in the Autobot Earth forces, Rook's analytical/tactical mind belies his tendency to sometimes break ranks and charge headlong into the oncoming enemy forces.
Not that Rook has much to fear from incoming fire. His durabyllium armor plating can withstand punishing blasts and hold up under crushing weight, and normally at the forefront of his mind is pulling some injured party from harm's way, a feat he accomplishes by switching to his equally armored vehicle mode and utilizing his powerful hydraulic claw. It's all in a day's work for this fearless and selfless Protectobot.
