So far, the most combat effective powers I see belong to Heather, Orion, Ray and Darrien. Of course, it goes without saying that everyone at this point won't lose to normal people, but I think these four are the most useful in a fight (This is considering their abilities ONLY)

Adding Vee, I'd agree with that. Emily seems like she'd be most useful getting information and wreaking havoc from a remote location (via her cellphone) - like the guy in the van from action movies as Vee pointed out. She'd be useful for planning and overseeing, less so in actual fighting unless it was a game of strategy. She knows tai chi though!
