OK, here's the character concept Numbers, Rough Draft. It turned out a bit more powerful than I had first intended. If you want me to tone him down, just ask, but I think he's pretty cool as is, has a couple pronounced flaws (Only +6 Reflex & Will), and fills his intended Niche (Tank, pun intended) well.

As you can see, he's a couple points over right now, I intend to fix that (somehow) in the future, as well as doing a few changes, probably.
If you wonder why/how any of the AP vibration powers should be there, just ask.
Thoughts, anybody?
