Joystick

[PlatinumJoystick]

Name: Joystick
    Age: 20
   Race: Unicorn
Gender: Male
  Talent: Gaming
   Work:Currently Unemployed.
    Desc: A stallion hailing from Fillydelphia, Joystick could seem a little off to strangers, but he's a good friend to those who he knows. He spent most of his childhood spending time with his compadres Arc and Flame. They stole things when they needed it, and sometimes when they didn't. He became increasingly good at the art of the steal, going so far as to start a tally of the amount of times he made off with something and was caught. This tally ranks at 75-1.

Him and Arc got out of the underground to try and lead law-abiding lives. They managed to keep this up until mobsters found Arc. When Joystick returned, Story Arc was 'gone'. He still continued to attempt to lead a normal life, and was successful until eventually relapsing into his criminal habits.
