Howitzer Impact

Howitzer Impact is a Super Move performed by Katsuki Bakugo using the Explosion Quirk.

Description
Katsuki takes to the air and uses 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 Giant Ice Wall.

Weaknesses
The basis of Howitzer Impact is using the combustible nature of oxygen, especially accumulated oxygen. So if the said element is ignited too early, namely by another source, Katsuki puts himself at risk for serious injury as the tornado of oxygen would explode preemptively. Despite being aware of the combustible nature of oxygen that he he had amassed, during the climaxof his battle with Shoto, Katsuki failed to realize that the accumulated oxygen of his Super Move would instantly ignite if Shoto's flames had made contact with the twister of oxygen.
