I've never managed to get close enough to one to be able to tell, but glasslike shards from the Needler gun draw blood (and...kill a certain cast member, sob) so I'd imagine a sharp claw/teeth would get through. She'd have to take down their shields first, but that wouldn't take more than a few smacks.

YEAH although he can stop short of killing her if you prefer. :3 Stabbity doesn't need to equal deathhhh.
