Chainbot



When Ziktor's attempt to legally cut down an old forest failed, the robot known as Chainbot was assigned to destroy it completely. He was stopped by Ryan, though he wasn't shown to be destroyed. In Season 2, after the self-destruction of Grimlord's dungeon, Chainbot survived as a mere head. He attacked Ryan and was soon destroyed afterwards, inflicting pain on the weakened Ryan as well. Fits the category of Decimator's army.
