How it was defeated
When Executioner attempted to kill Ratte with a super charged shell, he used his Mimic power to quickly swap places and which his own shell hit him, destroying his frontal shield. Ratte then realizes that he had found the reactor on the Executioner and tried to destroy it. He fired a few shots which destroys the ice and chains that's protecting it. Executioner had sent back some more firepower and which destroyed some of Ratte's weapons and tools. He tries to destroy the reactor with a few more shots, but misses, Which Executioner fired three more shots that destroyed all of Ratte's weapons and tracks, exposing his amulet, leaving only his main gun still intact. Ratte hopes and believes in himself that he can do it and not miss, he takes a deep breath and fires his last shell, which it destroyed Executioner's reactor and is defeated.

When Executioner was released, he killed the faceless one, and stole his powers. He was eventually defeated by Leviathan(Mimic)
