Powers and Abilities
Giran was powerful enough to get to the final rounds of the 21st World Martial Arts Tournament, thanks to his species being stronger than humans. It is unknown how Giran ranks among his people, but Giran is super humanly strong, being able to kick around normal level martial artists with ease. Thanks to the wings on his back Giran can fly as well. His final ability is to use a sticky substance produced by his body called merry Go Round Gum to subdue his opponents.
