So .........What if Groot was a member of the Devouring Earth?
Slightly sidetracking from the sidetrack, but you can make a fairly decent Groot-alike in Icon with the Omega pieces. Based on his MAA moveset, I'd probably make him a Bio/SS Tanker. Due to the lack of appropriate heads or tails, Rocket would be difficult to make visually, but I'd peg him as a Beam/Dev Blaster, probably with Munitions Mastery. Drax is probably a DB/WP Brute, Gamora a BS/Inv (or SJ/Inv) Scrapper, and Star Lord... hm.... Traps/DP Defender (probably with the Concealment and Presence pools, particularly after their I24 revamps).
... have I mentioned yet that I still miss CoH?
Are we there yet? I just got an idea for a Beam Rifle/Devices/Munitions Blaster (one who - I must stress, in case any representatives of Disney or Marvel are reading this - will not, in any way, shape, or form, look like a raccoon).
