Protector. Named after Niko Bellic by a kid who couldn't spell. Equal parts engineer and psychologist, constant victim of wanderlust, and purveyor of cheap liquors. Likes silly hats, leather armor, and knives.
The good guy. Actually goes by his real name. Philsosopher, voice of reason, and filthy console peasant. Likes prog rock, British humor, and beefy five layer burritos.
Persecuted little. Named himself after the dictionary entry at a particularly bad spot in life. Curious and friendly once he warms up to you, or spastic when full of candy. Loves old B-movies with bad monster effects.
Freedom fighter. Named himself after a stupid biology joke, which he then went on to misspell. Weird dude, loudmouthed and outgoing. Loves biochemistry, electronics, and dancing around in his underwear to Korean popstars.
Warrior. Goes by her real name. Antisocial and almost entirely avoidant of everything. Likes taekwondo, icky health food, and conning people out of whatever she can get.
Macho man. Named after the Roman numerals for 12, being an important date in his life. Aggressively straight. Likes nightclubs, guns, being fancy, and old Louisiana blues.
