“Wise, well-educated and worldly, Usus has years of experience in the gladiator games. He is often coarse in his language but cares deeply about training gladiators and helping them reach their potential.” – League Training Manual, page 9
Usus is an old friend and contemporary of either Munio in the Valens storyline or Orin II in the Ursula storyline. He serves as the school's chief adviser as it advances and moves from region to region and is the only character who does not appear in combat, although he provides the initial tutorial on how to fight to either hero. Usus also gives helpful tips just before battles ("Ask Usus") and can be asked questions from the school menu. He is voiced by Kristoffer Tabori (credited as Kris Tabori).
