The Quadricorn is an enemy from Final Fantasy X-2. While a bit stronger than most normal enemies encountered early in the game, it is not a big threat and can be disposed of in various manners.
In the Fiend Tale endings, a notable Quadricorn was created from the spirit of a blitzball player who was Ohalland's rival and tied with him during a match, Quadricorn remained on Spira due to the promise he made to the High Summoner-to-be to settle things in another match. However, Quadricorn learns of Ohalland's fate and begins to lose hope as his fiend body renders him unable to play blitzball. But when Ohalland intervened and restored his competitive will, Quadricorn sends himself to the Farplane to properly settle things.
