Kogu

Kogu, known as Gokua, is one of Bojack's four Galaxy Soldiers. Kogu is shown to be an arrogant Hera Clansman and a heinous warrior, attempting to blindside Future Trunks with a ki blast and warning the hybrid Saiyan that he was not someone to take lightly. He has no regard for the rules of the Intergalactic World Tournament, casually bringing his sword with him despite the restrictions. However, Kogu's arrogance proved to be his downfall, as he chose to continue taunting Future Trunks instead of finishing him off when he had the chance, ultimately costing him his life. Kogu waits in a field during the Intergalactic Martial Arts Tournament, posing as one of Mr. Satan's champions. He encounters Future Trunks and ambushes him with a Full Power Energy Ball fired from a tree he was sitting on. After Future Trunks scolds him for bringing a sword into the tournament, Kogu proceeds to attack him, catching Future Trunks by surprise, while also telling the latter that he is "not someone to be trifled with." After Trunks puts up a good resistance, Kogu transforms near a body of water, and further overwhelms Future Trunks with a series of brutal blows and clotheslines. He then tells the young Saiyan to surrender while he still could. When Future Trunks refused to surrender, Kogu prepares to finish Future Trunks off with a blow from his sword but ends up caught by surprise when Future Trunks turns Super Saiyan Second Grade. In the end, Kogu ends up with a broken sword and is taken down.
