Ymir sketches

Concepts for a new COW OC.
Unit 999, Ymir.
He's a Synthesian, compacted brain matter that is ornamented in armor coating. The brain is Ymir himself, it appears much like a human brain but is built quite differently. The brain is capable of emitting waves allowing the body to move like a faux nervous system. The helmet is very thick, equipped with a translator of his thoughts.
I decided to give him a suit...you know, cause it's sexy I guess? Planning to work in Infirmary along with Dr. Stillman and Inka and the others and such.
He's a tall drink of water, yeah, but quite the dry sort of ragamuffin. Doesn't emit to much emotion, prefers rationality and such, very zen guy.
His hobbies include folding clothes, color coding things, rebuilding motorcycles and ships of the like, playing chess and dominoes, debating, reading, things you'd expect a smart fellow to like.
I'm still iffy on his ability.
I was thinking either electric pulses or a light-saber-ish blade.
Yerp...tell me what you think.
