A giant robot created from the combination of the five DECEPTICON Commandos. Having no interest for anything but fighting, Ruination is so atrociously cruel that even Megatron fears him. He can change around his limbs at will, adapting instantly to various battle conditions with such forms as Flight Mission, which specializes in aerial combat, and Land Mission, which specializes in ground attacks. His two rifles, fusions of all the DECEPTICON Commandos' weapons, can destroy an entire city.
