Howitzer Impact

Howitzer Impact is an Ultimate Move performed by Katsuki Bakugo using the Explosion Quirk.

Description
This move is one of the strongest moves in Katsuki's arsenal, which involves Katsuki taking to the air, and then using explosions to propel himself in a circular motion to create a tornado. The ensuing twister collects oxygen and momentum to fuel the subsequent explosion.

Katsuki releases the enhanced, aforementioned blast upon impact with the ground. The technique and its effectiveness are comparable to that of a missile. It was first used in Katsuki's match with Shoto Todoroki during the U.A. Sports Festival. It had enough destructive force to completely destroy Shoto's Heaven-Piercing Ice Wall. He has also shown that he can release the fueled explosion in mid-air, without having to make contact with the target. Katsuki is capable of maintaining the tornado's gyration even as he attacks, as shown during his final battles with Nine and the Serpenters.
