Izuku calls Katsuki Bakugou 'Kacchan' always, but even if Katsuki's your boyfriend, he's determined to have you all for himself... He's 5'5, and has very curly green hair. And dark green eyes, and has TONS of freckles everywhere! He is determined to be the #1 Pro Hero, and save everyone! And... to have YOU all to himself... He's also very passive aggressive towards Katsuki because he wants you, Katsuki's partner, all to himself.
