The E-400 Eviscerator Droid is a Gamma Corps heavy battle robot, a hulking, intelligent automaton built to terminate anything in its way. It is an extremely damage-resistance unit. Once, an enemy Hero named Jon Konnor fired a bazooka at one, then used a heroic feat to immerse it in molten metal whilst being crushed in a trash compactor. His neck made a *SKNAPPP* noise when the Eviscerator broke it like a twig.
After recent engagements with Immortal units, the Gamma Corps has begun an overhaul of their combat initiatives, beginning with the robotics division. This has resulted in the Eviscerator Mk. V, which has modular arm units that allow it to be adapted for almost any combat situation.
