Here are some suggestions that are not in the poll, since they asked for that as well.
Alter Physical Structure powers: As many sets as you want to put into the game, each based on a different type of material/energy/element. Quite a few are well suited to Tankers. EG: Alter Physical structure: Metal, Stone, Crystal.
But anything goes here. Fire, water, ice, light, plasma, smoke...etc., etc. Some would be very difficult to code, others probably wouldn't take much at all.
Another possibility; Stretching/Elasticity, aka Mr. Fantastic. All sorts of possibilities here, from ranged attacks ( stretching out fists? For a scrapper?!!?), to defense bonuses, hold attacks, and fun travel power options (Tweak Super Jump to bouncing like a ball.)
That's all for now. If I think of some more, I'll post em.
