I took the advice @3dc gave me about giving Xoel more arms, but I thought it would be nice to give each arm a particular function or object to carry, even though I must think on the items he will bring with him.
I also improved the anatomy of the character, and that gave me a more clear idea of the volumes that allowed me a more focus on clothing and that kind of stuff.
I'll design these three as different from each other as I can, thus the selection will surely be a nice and well-planned design.
I'm still thinking in the superpower, but maybe it will be the power of reviving corpses and rotten organisms to use them in the battlefield. Any suggestions?
