Strongarm

Strong Shoulder is a Quirk used by Kendo Rappa.

Description
This Quirk allow Rappa to move his shoulders at extreme speed and power, giving him commensurately fast and strong punches.

He is able to throw a huge flurry of punches that are incredibly quick, and immensely powerful. This Quirk is strong enough to shatter Eijiro's Red Riot Unbreakable form with ease, as well as whittle away at Fat Gum, a Pro Hero with a defensive Quirk.

However, this Quirk is unable to break Tengai's Quirk, despite its power.
