Flip Hero
This fellow may look small and simple, but he's an elite fighter determined to put an end to the evil battle plans of the machine warlord, Cruiser Tetron! He's the hero of the bullet hell game, Hero Core. He can fly in any direction and shoot left and right. When properly equipped, he has a blade that can cut metal and deflect big energy shots. He's stopped Tetron countless times before, but the fiend's machine army just rebuilds him every time.

How he ended up in this game is a complete mystery.
