Re: Fictional Bad Guys Become Real
War Wolf would assume this is the work of The Producer ... for those unfamiliar, it was a villain from an older Champs supplement (Strike Force?) who would create robots based on various movie properties to run amuck. Anyway, tactical sort that he is, he'd check case studies and see if they're behaving in ways you would expect from their fictional counterparts; if so, do some research and see what their weaknesses are and exploit them. For example, Mumm-Ra can't stand the sight of his own face. Cobra Commander is a complete coward. Use holograms or other disguises to see if they can be 'baited' with their on-screen arch-enemies ... like mocking up a fake KITT.
Vixen ... might maybe have heard of Megatron from the newer Transformers movie, but that wouldn't be a lot of help ... the rest of 'em, she wouldn't know from Adam, except for Vader. So, she wouldn't likely even know she was facing realized fictional charaters until someone actually told her this. She's not big on 'the classics'. As such, she wouldn't take their MOs into account and probably stick to a pretty direct approach ... stop the bad guys and try to trail 'em back to their headquarters.
