Well I never really call any of my characters' powers "magic", at least not usually. It just seems too generic, I dunno. xP For instance Alien's magic isn't so much magic as it is something he can simply do. Using any of his abilities aren't like spells any more than they're like "natural" body functions.

As for his genocidal tendencies, Alien would certainly want to take advantage of that. ;D If he's got any sort of dark attributes, it will attract Alien's attention. If he's trying to fend off those dark habits, Alien will do his best to stop him from doing so.

Edit: lol, reading Tatek's profile. So far he seems to be perfectly built for defeating Alien. I love it. xD Though I'm curious: Would his Magical Immunity cancel out the natural healing properties activated after Alien does damage?
