The ultimate badass. THE Pokemon Master. Not to be confused with the joker called Ash. This guy can wipe the floor with you without even breaking a sweat. Even if he loses, you'll never want to challenge him ever again. The piercing red eyes that stare into your soul and rip it apart will make sure that you will never want to fight him again, no matter the outcome of the battle.
I've heard that Red is the only one who can catch other Trainer's Pokemon. He just doesn't do it because their Pokemon are weak.
