Katsuki "Kacchan" Bakugou, is a 15 year old male- he used to be Deku's and Sazuki's friend, but when he found out about Deku being quirkless. That's when the bullying started, when Sazuki tried to stop it she got herself dragged in it to the bullying, Some say that Kacchan is the way he is because he was insulted by his favorite hero (which i'm going with). Kacchan/ Katsuki is Cocky, r00d-, and many other things, he is only now warming up to others, which is good, kinda. Katsuki/ Kacchan stands at also 5'9, (i'm just no longer talking about weight now- 😑) katsuki's quirk is explosion, he sweats nitroglycerin like sweat which allows him to blow stuff up at will when quirk is activated.
