Robots...Old style Cylons with their signature robot voices, "By your command."
Silent Terminators would work too.
Thugs: My favorite class. Thugs with guns. and I loved the Gang War power where 10 to13 low level thugs popped in shooting everything in sight.
*** How about Mafia types...with guns? Let me customize appearance, please!
*** or cops if I'm playing a hero.
*** Trench coats and masks...My team of Green Hornets. and Kato.
*** I want fully customizable girls...chicks with guns...I make the outfits and faces.
the way it should be. cat-girls, or whatever. The one with fire could look like, I Dream of Jeanie. Killer Secretaries. Bunnies. all the same or all different.
Undead. My least favorite.Too slow. Give me NAZGUL! and speed them up!
Demon summoning. Yawn. Let me customize them into low level costumed heroes/villains. Then I could be my own team!
