Ok I know what my next PC is.
It works a trifle better with Jadeite as Zim.
Jadeite: "PITIFUL <i>monkey</i> creatures! I shall suck all your energy with my energy-sucking… sucker… thingy. Youma!" (pause) "…Why are you eating your leg?"
Redhead of the Week: "…Because it tastes like bacon."
Jadeite: "There is no time for eating on our Sacred Mission, Youma! Now, DESTROY THE SENSHI!"
RotW: "YES MY MASTER!"
Jadeite: "My <i>spleen!</i>"
Usagi: "Ami! Ami! You gotta help!"
Ami: "I'm playing video games, Usagi. If this is not important I will destroy you."
Usagi: "It's the new girl at school! She's <i>stealing everyone's organs!</i>"
EDIT: Of course, that version of Ami <i>would</i> be dying her hair blue. And wearing goth clothes.
