The League Warrior is an enemy in Final Fantasy X-2.
He usually is no threat, especially for the point he is found in the game. Take him down before he uses Hi-Potion to heal.
Its Japanese name translates to Alliance Trooper. Trooper (abbr. Tpr) from the French "troupier" is the equivalent rank to private in a regiment with a cavalry tradition in the British Army and many other Commonwealth armies, including those of Australia, Canada, South Africa and New Zealand.
