there's a second or third quirk that only 1 out of 10 people could have so there was at least 2 people that had this second or third quirks depending on how many quirks you originally have. its call 'animal' and its really rare to have it. bakugou and todoroki have this quirk and every valantines day its heat season, you can either be a wolf, cat or bunny. when you have this quirk you can be an alpha, beta or an omega and unfortunately bakugou is an omega and cant smell his soul mate. he can smell danger. they can change into the acctual animal or just have there ears and tail. they also enharte the sense of the animal. top= todoroki bottom= bakugou thats the second quirk in a full discription so ya. ~warnings~ deprsssion there might be smut
