Style Wild as a Ted Kaczynski style anarchist. He did grow up in the forest and no doubt would have some issues integrating to modern society (except CWCville).
Or Angelica as a depraved schizophernic IRA member who is driven by "God" to kill. She's barely kept under control by her devotion to Father.
Bubbles would be a stupid valley girl who would be the least evil member of the Combo. Of course, because she's borderline retarded, the others force her into committing various atrocities.
Wild: "Here, shoot this pig." Motions to police officer,
Gives Bubbles a Mauser C96.
Bubbles: "But, like, won't that hurt him?"
Wild: "No, your just... Putting him to sleep. He's very tired, but doesn't want to to go to bed. The pistol will put him to sleep."
Bubbles (clueless grin on her face):
"Oh, okie-dokie! Time for bedtime!"
Puts barrel on the cops forehead. The cop tries to scream, but his gag turns his protests into incoherent grunts.
Bubbles pulls the trigger. The pistol operates as expected.
Bubbles: "Yay, he went to sleep! I did a good thing today!"
Wild: "Yes. Now come, The Chaotic Combo has many more... good things... to do today in Father's name."
Bubbles skips off like an idiot, Wild trailing her.
