Vibrate gives the user the ability to generate vibrations, or shockwaves, which can travel through virtually any medium. Yo most notably uses this ability to shake things he touches with his hands.
Vibrate allows Yo to control the speed and strength of his vibrations, including how long the intervals are between tremors. Vibrating most objects vigorously will cause them to break and break. When used on the ground, Vibrate can create small controlled earthquakes.
Due to the Vibrate's after-effects, this Quirk can grant the user resistance to vibrations, such as hypersonic attacks.
Yo's body is susceptible to aftershocks if he makes them too fast or strong, leaving him unable to move. Vibrations that are too strong cannot be stopped on his whim, so they must dissipate on their own.
Yo has demonstrated his use of Vibrate against large groups of enemies, showing how his earthquakes can disrupt enemy formations as it destroys their foothold, weakening them in the process.
Yo has developed a natural resistance against vibrations due to the after-effects of his Quirk subjecting his brain to constant trembling. This gives him a small advantage against other Quirks that rely on vibrating waves, like Orcinus.
He later uses his Quirk to fight against an escaped Muscular, seemingly being unable to match his strength, however it turns out his vibrations were strong enough to greatly weaken Muscular's muscle tendrils, allowing Izuku to defeat him with ease.
