Big John

"This giant mechanic puppet was developed by the Amadeus Army. It shows its face after getting harmed."[]

Overview[]

One of the toughest stationary defenses in the game.

Its standard attack is a missile and its long attack is a trail of flying acid bombs; its special attack is to launch a trail of plasma balls from the ceiling out of a cannon. When Big John's health is low or in middle, it will reveal itself after taking certain damage to it.
