Dreadpool

Deadpool (Killogy) is an alternate version of Deadpool from Earth-12101 who went insane and started a killing spree after finally seeing the truth: that they are all just fictional characters created to entertain other worlds. It all started when Professor X and Psychoman tried to cure his insanity which accidentally led to the erasure of the two voices/narration boxes in Deadpool's head which kept him sane. The loss of his narration boxes led to the ascension of a red narration box, a symbol of Deadpool's uncontrollable rage and monstrosity. The red narration box told Deadpool that they are all fictional characters doomed to eternal torment for entertainment, and since Deadpool is the only one aware of this, it is his duty to put all fictional characters out of their misery. Deadpool set out on destroying his own universe, other multiverses, literary inspirations and even other Deadpools.
