Acid Sweat

Acid Sweat (酸化汗) is the Quirk of Masaru Bakugo.

Description
His palms can secrete an acidic sweat with combustive and explosive properties. If he rubs his hands together, he can create explosions, but unlike his son, he cannot forcibly secrete it, and it comes out like normal sweat. This, along with his wife's Quirk, is why Katsuki has to secrete sweat in his Explosion Quirk as they become more powerful.

Trivia

 * This Quirk is similar to Mina Ashido's Acid Quirk but instead of releasing large quantities of acid at once he releases it gradually like sweat.
