Rampage



The Rampage is a gigantic fighting robot created by Megatron to destroy his and Optimus Primal's new rival Blackarachnia alongside Optimus Primal's other new giant Depth Charge in the episode "School Girl Crushed". However both robots were easily defeated when Blackarachnia sprayed them with some water and short-circuited them.
