«Did you have your fun mocking me all this time? You have a Quirk, right? Why won’t you use it? Are you underestimating me?»
Prideful and thirsty for victory, Katsuki is always looking down on others, especially Midoriya whom he named “Deku” (meaning “good for nothing”) and treats like garbage since they’re four-years old.
His rage and frustration skyrockets when he’s facing his lame childhood friend because Deku dares to oppose him. Even more, he’s fighting him hard, dodging each and every of his attacks! For the first time in Bakugo’s life, it’s not about winning anymore… it’s about putting Deku back where he belongs: below him, in the dirt!
This Xtra by Tsume’s figure depicts this exact scene where Katsuki uses his grenade shaped equipment to increase his Quirk’s efficiency. He’s willing to end an already too long fight, whatever the costs. His eyes filled with rage, he triggers an explosion so big it will literally blow a part of the building they’re standing in!
