Why does this version of Satana have dark hair? She's most notably a redhead, and even the comic book on her card depicts her as a red head.

Because throughout the entire Thunderbolts stint, she had black hair. Honestly that's the only time I (and probably many others) have ever read anything with her in it, plus it's the most current appearance.

One of my most wanted characters to be clixed, but not with such lame defence stats/no defence SP. Going to cry in my cereal now.

For a character you need to attack with to utilize their specials, she sure has middling offensive stats. Needs extra support to be effective. Easy to hit, not enough bite offensively, limited support capability, all for a hefty 82 points.

I've tried using her a few times and she doesn't really pull her weight, even when she's doing well. The biggest issue I have with her is the switch to long range mid dial. If she had the ability to ignore opposing characters for movement, it would have gone a long way both in playability and comic accuracy (She always teleports around and ignores people).

If you Thunderbolt to give her Mystics, then she becomes a tiny bit more annoying due to the Toughness and Steal Energy, but at that point you're paying a lot for her.

I still wonder why her picture is on the Legion of Monsters ATA card and she doesn't have the keyword?

What's even more ironic is that the comic on the back of her card that features her on the cover is a Legion of Monsters issue.
