Bujin

Bujin is a member of the Hera Clan and one of Bojack's four Galaxy Soldiers, a group of space pirates who were imprisoned by the four Kais long ago. He is the smallest member of the group and relies on psychic abilities rather than raw physical power, making him tactically distinct from his teammates Kogu, Bido, and Zangya.

In Dragon Ball Z: Bojack Unbound, the Galaxy Soldiers are freed from their imprisonment when King Kai's planet is destroyed during the Cell Games. They infiltrate a martial arts tournament being held on Earth, gradually revealing themselves and attacking the competitors. Bujin uses his psycho thread technique to immobilize opponents, trapping them in energy wires that drain their strength and leave them vulnerable to attacks from his allies.

During the climactic battle, Bujin helps restrain Gohan using his threads while the other Galaxy Soldiers attack. However, when Gohan transforms into Super Saiyan 2, he shatters the psychic bonds and eliminates Bujin with a single powerful blast. He also appears briefly in Fusion Reborn and in Super Dragon Ball Heroes during the Supreme Kai of Time Saga.
