Explosive Speed: Cluster

Blasting Speed Turbo: Cluster (ターボ クラスター) is an Ultimate Move performed by Katsuki Bakugo using the Explosion Quirk and the Cluster technique.

Description
Similar to his Explosive Speed, Katsuki positions his arms behind him and uses his explosions to propel himself forward. In this version, he employs the Cluster technique, propelling him to speeds far greater than he could normally achieve.

He first inadvertently used this technique during the Paranormal Liberation War to save Izuku Midoriya from Tomura Shigaraki's Rivet Stab attack, and then later to arrive and assist the remaining heroes in attacking the Near High-End Nomu.

Blasting Speed Turbo: Cluster gets its name when Katsuki uses it during Class 1-A's fight to bring Izuku back to U.A.

Trivia

 * The Japanese name for Blasting Speed Turbo: Cluster (ターボ クラスター) indicates that it is a variation of Katsuki's Explosive Speed (ターボ). However, due to the official English translation, this indication has been lost and instead implying it is only being similar rather than being a derivative.
 * Following the introduction of Howitzer Impact: Cluster and the establishment of Cluster as an upgrade of existing Ultimate Moves, it can be assumed that the Japanese name was mistranslated and is, in fact, a derivative of Explosive Speed.
