Omg I have all of those books. I used to absolutely LOVE them. Especially Soul Killer, the one you're referring to when they had to team up with Dracula. That. Book. Was. Everything. Care to discuss it?
Oh and I never did complete my collection of the Gamme Quest Trilolgy. I had the first one. And in that one I remember an epic showdown between her and Iron Man. She took that motherf*cka out. HBIC style. I think she even dissipated one of his repulsor ray beam things with the atmosphere before it even touched her. Omg she was so boss in that fight. Did she have any other great moments in the rest of that trilogy? I wasn't a big fan of the Chaos Engine one. She was just kind of...there. She did however beat the breaks off of Nazi Meggan if I'm correct. With handcuffs on no less.
