Rex: Well you will lose.

Rook: I feel like this is not his real plan.

Rex: Ah, the revonnaghander is correct, my real plan is to turn every Dactilosapien into a Vaxasaurian. But, I will not stop there. After that, I will turn every species into a Vaxasaurian, except the Pyronites and Methanosians of course.

Humungousaur: Dude, that sounds like the worst plan ever.

Rex: No one asked you, but also I will evolve myself into an evolved Vaxasaurian, so I can rank superior!

Humungousaur: And how you gonna do that?

Rex: like this. Presses a button and is engulfed in red light

Humungousur: transforms back to Ben Oh man!

Rex: Ben Tennyson, meet Ultimate Rex! Now I rank superior of all species, besides the Pyronites and Methanosians.

Ben: Active mode, aw yeah! transforms into Humungousaur

Humungousaur: Humungousaur!

Omnitrix MK10: Omnitrix MK10 must acquire DNA sample. a green light is pointed at Ultimate Rex

''Humungousaur presses the Omnitrix MK10 sample and is engulfed in a green light. When the green light is gone, Humungousaur has grown green skin and blue chest gear and now has a mace on his tail''

Ultimate Humungousaur: Ultimate Rex, meet Ultimate Humungousaur!!

Kevin: Woah turns back to Osmosian form is that even possible?

Ultimate Humungousaur starts punching Ultimate Rex, and Ultimate Rex fights back

Ultimate Humungousaur: I wonder how I can stop you Rex?

Ultimate Rex: Its Ultimate Rex! And the only way you can stop me is by reverting my DNA, but I destroyed the only thing that can turn me back!

Gwen: Ben! The Omnitrix is also a DNA reviver. You can change his DNA back.

Ultimate Humungousaur: Here goes nothing. Omnitrix MK10, fix species DNA, Code 1210 Ben.

Omnitrix: Code accepted! Reverting DNA to Vaxasaurian.
