The Dark One has arrived.

Y/N was sent away from his world amd near dead, he was found and changed into something called the Alpha Nanite, and after being beaten into a corner by Rex Salazar and Ben Tennyson, Y/N created a portal out of pure instinct and in that small eternity alone, he grew stronger, shedding his ability to transform but gaining the power to use the powers of the alien forms in the Ultimatrix....except one and he used all of his power to create an alternate version of himself who instead of the Ultimatrix had created and bonded to the complete Omnitrix and in that instant....

He became the single most powerful being in existence, so he searches for the perfect world to rule....

And after many, many years of searching...he's found it.
