A Certain Powerful Omnitrix. (とある パワ の Omnitrix)

Ultimate Power

"ALBEDO!!!" Ben roared as he changed back into a human. "Give it up now!!!"

Albedo gave a twisted laugh. "You expect me to give up!? After all I have gone through to get to this moment!? You expect just because there are 2 of you and just 1 of me that I will surrender!?"

"Well yeah,we were kind of thinking that." Touma muttered.

"Well think again foolish human mongrels. You seem to forget that I posses all of Tennyson's powers and that foolish boy over there is a mere level 0, who is powerless against me!!"

"That may be so Albedo!" Mikoto shouted. "But they have more conviction then you ever could. They are stronger then you by a long shot!"

Albedo groaned. "Please... You sound like you were talking with that old geezer Azmuth! That fool could never see what true power was. He created the Omnitrix, yet he could never see the potential it had as a weapon!! And when others did see that potential, he attempted to lock that device away, only to have be found by a pathetic human boy!!"

"Yeah?!" Ben said as he activated the Omnitrix once more. "Well this pathetic human boy is about to kick your butt!!"

There was a green flash and Ben was once more the muscular, large, tough armored, dinosaur man Humungousaur.

"Oh please. I have something even better then that." Albedo said.

Albedo took a green box off his desk and touched it to his Omnitrix. The box phased into the red Omnitrix like a hologram. All of the sudden, the red Omnitrix began to glow a bright red aura.

"New application received." The red Omnitrix said in a female voice. "Upgrade to Ultimatrix."

Albedo pressed the face plate on his Omnitrix and turned into Humungousaur like Ben did. Only Albedo's Humungousaur form had red eyes instead of green and his skin was a darker shade of light brown.

"Some kind of upgrade Albedo?" Humungousaur said. "Looks like you're constantly needing new shams just to keep that knock off running!"

"This isn't a knock off anymore Tennyson." Said Anti-Humungousaur. "Not only can I change into anything you can... But I can also evolve those aliens into their Ultimate forms!!"

Anti-Humungousaur pressed the Omnitrix crest on his chest. Instantly four metal triangles spread out from the Omnitrix badge in an x shape and Anti-Humungousaur began to change. His muscles became bigger and his skin turned dark green. A giant metal shell with spikes emerged on his back and metal plates grew onto his chest and abs. A small metal shell grew on the top of his head and around the sides of his head with two giant horns growing on the sides of his chin. On the end of his tail, a giant spiked Morningstar emerged.

"Ben Tennyson, meet......Ultimate Humungousaur!!!!"

Ultimate Humungousaur grabbed Humungousaur by the face and threw him out the melted window. Humungousaur fell into the street below, creating a giant crater in the street.

Humungousaur got up from the crater groaning.

"It's going to take a lot more then that to stop me Albedo!!" Humungousaur shouted at the Radiowave building.

At that moment Humungousaur saw Ultimate Humungousaur leap out of the top window. He had both his fists pointed at Humungousaur. The green fists then morphed into what looked like five barrel cannons. From the cannons, rocket like objects shot out leaving a smoke trail and the tell tale whistling sound that proceeded missiles.

"Missile hands!?" Humungousaur shouted. "That's totally unfair!!"

Humungousaur ran out of the way just in time as the missiles hit the street and erupted in a wave of powerful explosions. However, Humungousaur was still knocked off his feet by the remaining force from the explosions. Ultimate Humungousaur landed in a crater just 10 meters away from Humungousaur.
