@Chaotic ChaoRedrum has already expressed interest in a Green Lantern style construct generator, Rune_Alchemist already has a barrier creator, and Inertia has a character who generates explosions. And we already addressed the overlap with the chains and other constrictors, so...
Hmm, as far as "originality" goes, I'm not disallowing "cliche" powers or anything, it's just that I don't want a lot of overlap between people all being able to do the same thing. Even with everyone so far having interesting powers, you can see by looking at some of our skills that there's still some overlap (things like propulsion for high speed movement using explosions or psychic powers or sheer muscle) but that's to be expected simply because I'm sure everyone here is creative enough to find a lot of uses for a single power. So maybe you could go with something similar to plasma manipulation, like electrical manipulation or fire manipulation? We don't have any "pure elementals" yet, so to speak.
