Red is the main bird, with which you start the game (at the very beginning you have him at your disposal). In the world of RPG, you can simply say that he's a warrior - he fights by using a one-handed weapon and a shield, inflicts moderate damage and has the best defensive capabilities of all of the birds available in the game. Red is somehow self-aware that he, and really none other of the characters have limbs, and are just spheroid sprites. It is a mystery how they hold things.
