Kogu (Gokua)

Kogu, called Gokua in the original Japanese version, is one of the henchmen of Bojack in the movie Dragon Ball Z: Bojack Unbound. He was killed by Future Trunks, making him the only one of the Galaxy Soldiers not to be slain by or because of Gohan. His name is based off the Japanese word "gokuakuhidou", meaning heinous and inhuman. Bido, his fellow henchman, shares the second half of the word.
Not much is known about Kogu except that he is a skilled swordsman. He is the same alien race as Bojack and his crew, the Race of Hera; he even has a transformation similar to Bojack's. But in the end, his transformation was not enough and he was taken down by a Super Saiyan Trunks. Kogu ends up with a broken sword and death by a fist clean through his stomach.
Along with countless other Dragon Ball antagonists, Kogu makes a cameo appearance in the 1995 film Fusion Reborn when the residents of Hell make their escape to Earth
