A strong-willed teen from the village of Vale, Isaac is a Venus Adept, granting him Earth-based Psyenergy abilities. Alongside Adepts of the other three elements, he quests to stop the four elemental lighthouses being re-lit, which would unleash Alchemy: the force of reality itself. As an Assist Trophy, Isaac uses Psyenergy to Move fighters off-stage, Pound them with a giant fist, or Lift them into the blast zone!
