The Insane Mechanic/Chemist
Completely and utterly Insane. This kid will talk fast, and think faster than most computers. He loves to fix most things, and his nimble fingers help him fly through repairs. Also does the chemestry work, creating potions, poisons, etc.
The guy will help you one sec, shoot you the other. Can become loyal after a long standing time, but usually trusts nobody, even if his speech is friendly.
Any mechanical tool he needs, he's got. Wrenches, screwdrivers, the lot.
Doesn't usually carry a weapon, unless its the 9mm under his workbench. And any poison, or concoction he made up yesterday.
Was considered brilliant back in high school, but had to go on this mission simply because the world wouldn't except him. And he knew it.
