I'm not one for this, but damn you're hot. I mean, if I were to touch that whip, I'd probably be electrocuted and stuff. It'd hurt. I mean the invulnerability thing would make sure I don't die, but I wouldn't be too high and happy afterward.
The Wonder Girl costume is more modern (much like Superboy's "costume") but I like it anyway.
Can you move your arms freely? That was my biggest problem with that custome. I know it's not real life and I shouldn't be asking for practicallity all the time, specially with super powered heroes, but still... it looks really difficult to move your arms in that thing.
I liked the old idea of Cassie being a blonde girl that wore a wig when she fought crime. I thought that was a smart thing to do!
