A character who lives for a challenge. It doesn't matter where they are or what lies at stake, what they really love is the battle, the challenge of going against someone who is a worthy opponent, no matter what the venue or the game is. Usually they hold no grudges, and have no one they'd consider their enemy (their rivals, on the other hand...). Instead, they have those who they relish challenging again and again, so that they can enjoy themselves. Any series where the main focus is a form of competition, from martial arts to chess, has at least one of these. Subtrope of In Harm's Way
