You's Quirk allows him to shake anything he touches, allowing him to create earthquakes by touching the ground, for example. He can also control the strength and speed of the shaking.
His body, however, is susceptible to aftershocks caused by his Quirk, sometimes to the point of being unable to move if he makes the shaking too fast and strong. At the same time, his quirk made him somewhat more resilent to other vibration based quirks and let him shake off their effects faster.
- Quaking Earth (震伝動地 Shin Dendō Chi?): Using maximum power, You places his hands on the ground and shakes the ground, which unleashes a powerful earthquake that completely shatters the ground.
