Reinforcement

Reinforcement is Stick Brian's final upgrade from the Slush Invaders: Game. This upgrade allows him to attack right after the fighter of him finishes attacking, instead of only appearing right after the fighter <left< of him has finished attacking. This is represented by an icon that shows a miniature version of Stick Brian's upper body surrounded by a blue circle. If you use both fighters that are adjacent of him at the same time, then Stick Brian will only appear once until he is summoned again.

Trivia

 * This is one of the upgrades to show more than just the character in which this upgrade belongs to. The Reinforcement upgrade shows both Ben Stickobi and Stickhanh behind Stick Brian.
