Hiro

During his one episode appearance, Hiro was a loser at Shibusen that couldn't do anything right, and was constantly picked on or used by other students. One day, Hiro learned of Excalibur, and seeked out to be his partner. During his time with Excalibur, he was able to defeat Black Star, Death the Kid, and Kilik at the same time, by simply saying the name of an attack, which was followed by an explosion. Hiro was also able to complete all 1,000 of Excalibur's tasks, but the one thing he could not stand was his incessant sneezing. He later dropped Excalibur and took up weight lifting.
