Cluster (クラスター , Kurasutā?), full name Blasting Speed Turbo: Cluster ( 爆 ( ばく ) 速 ( そく ) ターボ クラスター , Bakusoku Tābo Kurasutā?) is a Super Move performed by Katsuki Bakugo using his Explosion Quirk .
Just like with his Explosive Speed, Katsuki positions his hands backwards, using explosions to quickly propel him forward, only this time, he condenses them to become stronger and faster, resulting in a flurry of bursts that blast him forward at incredible speeds.
Blasting Speed Turbo: Cluster's original Japanese name ( 爆 ( ばく ) 速 ( そく ) ターボ クラスター Bakusoku Tābo Kurasutā) indicates that it is a variation of Katsuki's technique Explosive Speed ( 爆 ( ばく ) 速 ( そく ) ターボ Bakusoku Tābo ).
