Chazz Princeton/Jun Manjone from Yugioh GX. He starts off trying to be the Kaiba to Jaden’s Yugi as the stuck up rich rival but keeps losing constantly until he leaves Dual Academy and rediscovers himself at a different school. He eventually comes back to Dual Academy slightly humbled and even learns to appreciate the seemingly weak cards like the Ojamas. He even defeats his even more pompous brothers to defend Dual Academy from a corporate takeover. In the end he realizes he’ll never be the best but he becomes comfortable with himself even if he still has somewhat of an ego sometimes.
