Ben 10: Alien Force, Season 3

Vilgax:
I'm about to conquer this planet. It doesn't matter where they've run. There's no place safe to hide.

Negative Ultimate Humungousaur:
You're right and our alliance has served its purpose.

Vilgax:
Hmm?

Negative Ultimate Humungousaur:
Our agreement? Once you give me Tennyson's Omnitrix, I can free myself from that hideous human form.

Vilgax:
There's been a change in plans. I'm keeping the Omnitrix.

Negative Ultimate Humungousaur:
Why are you doing this Vilgax? We had a deal. You don't even need the Omnitrix's power.

Vilgax:
True. I don't, but my army does. My bioids are synthetic soldiers with blank DNA all synced to the Omnitrix.

[Vilgax activates the Omnitrix and all the Bioids turns into Humungousaurs]

Biod Humungousaurs:
Humungousaur! Humungousaur! Humungousaur! Humungousaur!
