Acid Sweat

Oxidizing Sweat (酸化汗) is the Quirk of Masaru Bakugo

Description
His palms can secrete 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.
