Pewter

Ever the straight-laced researcher, this construct of metal and wire spends his days pursuing the noble goal of comprehensive technological advancement, if only for himself.  When he's not all smiles, hard at work at his newest project, he can often be found chastising juniors or those of less competence. Always snarky and bitter, this surprisingly sane scientist has a barbed tongue and a few crucial body mods, ready to reinforce the verbal lashing he just gave you with physical force.

Psychological analysis? Sufficiently stable.
