I'll jump in on this if I can - the last two zombie RPs I joined died quickly (no pun intended).
Looking at the submitted PCs so far, there's already at least one med student, so the character I was going to submit won't work out - consider this a placeholder while I brainstorm a new concept.
Name: Samuel Dravis
Weight: 160 lbs.
Appearance: A short, chunky man with a vaguely Hispanic tint to his skin, with ragged black hair and dark eyes and a broken, crooked nose. He wears gloves to hide the tattoos on his hands, favoring long-sleeved shirts and sweatpants for similar reasons.
Background information: Sam mostly raised himself, growing up with a deadbeat father and an alcoholic mother, very much an independent and free-spirited sort without any head for rules and authority. He dropped out of high school to join a gang, but split after a year in prison for dealing drugs. Now he runs a gas station, channeling his free time and energy into radical protesting with the occasional less-than-legal firebombing on the side.
Weapons: Double-barreled shotgun, switchblade, improvised explosives
Personality: Sam makes up for his short stature with an overabundance of energy - rude, crude, and (he thinks) hilarious whenever possible. Between his childhood, gang life, and prison time, he can be deceptively vicious and ruthless towards anything he considers a threat - but at the same time, he sticks like glue to people he considers worth being with.
Other information: Tends to be very insecure about his height, and reacts badly to short jokes.
