World Champion (ワールドチャンピオン, Wārudo Chanpion?) is a recurring weapon in the series. Originally appearing as the ultimate weapon for Wakka, it has since become the ultimate weapon for Tidus in later games.
World Champion is the Celestial Weapon for Wakka, obtained from talking to the barkeeper in the cafe in Luca after coming in at least third in a blitzball tournament, or win five blitzball games. She will ask the player to see the Celestial Mirror, and if obliged, will give the weapon. As with all Celestial Weapons, it starts with No AP as its default ability, and when leveled up with the Jupiter Crest which is obtained in the Besaid Aurochs locker room, gains Double Overdrive. After being powered up by the Jupiter Sigil (which is obtained randomly with 50% chance as prize in a blitzball league once the player wins all three of Wakka's Overdrives in previous competitions), it instead has the abilities Break Damage Limit, Triple Overdrive, Double AP, and Evade & Counter. Upgrading the World Champion with the Jupiter Crest also allows Ifrit to break the damage limit.
The World Champion deals more damage the closer Wakka is to his max HP, with the formula as follows:
- (10 + [100 * User's current HP ÷ User's Max HP]) ÷ 110
While not an equippable weapon, the World Champion appears as part of Shuyin's Terror of Zanarkand attack during the final hit.
