 In "It's Coming" and "The Eclipse", Hiro is mentally reverted into a ten-year-old, but still possesses his powers.After Ando teaches him how to use them again, Hiro shows great control over them even in his young mental state, being able to stop time with ease (and using it to play tricks), teleport himself and others and time-travel 16 years into the past with Claire Bennett.In "Our Father", Hiro's abilities are stolen by Arthur Petrelli, rendering him a normal human.
