You saw him clench his fists and growl, so that he then punched the wall, a bit of smoke forming from his palm, leaving it cracked. It was normal to see him mad, but this was serious..he never was THIS pissed.

"Damn it...God fucking DAMN IT!!"

He growled, shaking his hand in pain, and walked away. Maybe you should go over there and try to talk to him, but at the same time, he scared you. Bakugo gave snarl as he walked to the wall again, punching it again.
