Character: Justin "Grim Raker" Plankton

Once known as a quiet and mysterious high scholar and amateur boxer named Justin Plankton, Justin took to Cow’s philosophy of the rake and became “The Strangler.” Justin was killed by a katana-wielding high scholar pretending to be a Ninja. But after toxic waste was poured on his grave, his seemingly immortal corpse emerged with acidic skin and the ability to shoot energy blasts from his fists. Henceforth re-named; The Grim Raker.
