Ben 10: Alien Force, Season 2

[In some lab, Ben, Kevin, Magister Gilhil, and the Highbreed are all in a rig with their bodies chained up]

Magister Prior Gilhil:
I don't understand what's going on. That's the guy who tipped me off that you were impersonating Plumbers.

Kevin:
And he scammed Big Ugly too. [The Highbreed snarls at him] Well, he did. Don't snarl at me.

Ben:
I know who he is.

Masked Stranger:
Do you really?

Ben:
You had to be somebody who knows all the Plumbers and the Highbreed, but most importantly, you had to be someone with a grudge against us. Why don't you take off the dopey mask, Michael?

Kevin:
Wait, that's Michael Morningstar? The creep who tried to steal Gwen from– [blushes] Who, who stole all his powers from those girls at his prep school?

Masked Stranger:
When you ruined my plan, you nearly destroyed me, but over the weeks, my powers returned. Stronger than ever and so did my hunger. My old method of feeding is no longer sufficient.

Ben:
High school girls too tough for you, huh?

Masked Stranger:
To the contrary. I need more power than they can supply. Michael Morningstar no longer exists. [He takes off his mask revealing his hideous face] Now I am Darkstar.

Ben and Kevin:
[disgusted at his look] Eeuugghh!

Darkstar:
You did this to me and you will feed my hunger! (Shoots his beams at the four and starts absorbing their powers) I will take your strength and make it my own until you have no more to give.

Kevin:
(To Ben in a pained voice) If you can reach your Omnitrix – maybe Alien X.

Ben:
(in a pained voice) No! If he absorbed all that power, nothing could stop him!

Darkstar:
Eventually, I'll have it all, anyway.

Gwen:
Michael! [Darkstar turns around; disgusted] Ew. I swear you were better looking when we used to go out.

Darkstar:
Laugh while you can. I've got all the power of your teammates. Plus the Highbreed and the Plumber. How can you possibly hope to defeat me alone?

Gwen:
Who said anything about alone? (An army of DNAliens appear) They're pretty mad about you kidnapping their boss.
