Until I un-lazy enough to draw ras3, this is all the description you'll probably get.

Raseri is a tall but thin blue blooded troll. he's fit but certainly not muscular, as he is in fact rather feeble for someone of his blood caste.

Ras wears a faded black mechanic's jumpsuit, though he's probably only using half of it. with the front zipper all the way down he can wear the "pants" part while the upper shirt part hangs down behind him like some kind of coat tails.
His chest is instead covered by a white tank top which would be great for showing of his guns if ras had any.
other notable accessories include knee pads, blue boots, and his trademark blue goggles, which are more often on his forehead then not; though they have left a faint outline of dirt around his sapphire-blue eyes.

His hair is somewhat long, and often pulled back into a very short ponytail.

Ras's horns are quite... striking, in more ways than one. they start in the average place on his head but quickly curve forwards and jut out just above his forehead. They're vaguely reminiscent of a bulls http://s1.ibtimes.com/sites/www.ibtimes.com/files/styles/v2_article_large/public/2013/12/05/bullhorns.jpg and could potentialy stab someone if they tried to bump foreheads with ras.

Ras is a mechanic, and one of his most used gadgets is the Kanto-10
The Kanto has a number of parts to it, including a slim backpack with heavy straps that holds a husktop and the thus brains of the system; two tech-lined gloves; braces running down ras's back then down each leg to support the system; and most importantly: two metal arms. The arms can fold up behind ras, mimic his real arms, or slide over them entirely. notable features include sharp pointed fingers and a body armor-equse collar on the shoulders.
