Ultima: The Superior SpiderMan Exposed

(To be expanded upon by Temhota. Basic idea: The Avengers realize that the Superior Spider Man is actually Dr. Octopus possessing the hollow body of Peter Parker and that he had deceived everyone into thinking otherwise all along. Realizing he has been caught, "Peter Parker" transforms into a gross mutated version of his true "Doctor Octopus" form, intending to slay everyone in order to keep them quiet and prolong his life forever. But the real Spider Man from Spectacular Spiderman comes in to help the Avengers defeat Ock and reclaim Parker's body from the demonic spirit.)
