Howitzer Impact: Cluster

Howitzer Impact: Cluster (ハウザーインパクト クラスター) is an Ultimate Move performed by Katsuki Bakugo using the Explosion Quirk, Cluster technique, and Strafe Panzer support item.

Description
Similar to his Howitzer Impact, Katsuki creates explosions to propel himself in a circular motion, gathering oxygen and momentum to fuel the subsequent, more powerful explosion. However, by employing the Strafe Panzer and the Cluster technique, he is able to perform this on a much more deadlier scale, as well as spray explosions in all directions, further adding to the destructive power. Katsuki admitted this Ultimate Move is his most powerful technique.

This move is first used against Tomura Shigaraki during the Second War. However, Tomura managed to prevent any damage being done to himself by grabbing Katsuki's arm.
