Kogu waits in a field during the Intergalactic Martial Arts Tournament, posing as one of Mr. Satan's champions (whom he and the Galaxy Soldiers had murdered earlier). He encounters Future Trunks and ambushes 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." He then transforms near a body of water, and further overwhelms Future Trunks with a series of brutal blows and clotheslines.
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. In the end, Kogu ends up with a broken sword and is taken down by a fist clean through his stomach from Super Saiyan Future Trunks. However, Kogu's assault has worn Future Trunks out enough to be easily ambushed and knocked out by Kogu's master, Bojack.
Kogu is one of the only two Galaxy Soldiers who display the ability to transform. Despite this full power state, he is killed in one piercing blow from Future Trunks in his Super Saiyan form which demonstrates that his power in his full power state is lesser than Bojack who easily manages to overpower Future Trunks, Vegeta, and Piccolo in his base form.
