as you may have expected, next up is Groot.
i ignored old-Drax's energy blasts, but i couldn't ignore old-Groot. when i was a kid, Groot was one of the bad-asses - invading planets, experimenting on life forms, and screaming up a blue streak. (and he had the "I am Groot!" even back then.) to get the old-Groot in, i used his IA and a special card to cover his abilities that would translate into Energy stat points, and put them into his Intellect. and who can really tell where his intellect sits on a grid now-a-days, anyways?
