"Someone not to be trifled with, boy!"
— Kogu in response to Future Trunks' questioning of him in Dragon Ball Z: Bojack Unbound

Kogu, known as Gokua (ゴクア Gokua) in the Japanese version, is one of Bojack's four Galaxy Soldiers in Dragon Ball Z: Bojack Unbound.


Like other members of his race, Kogu has teal colored skin and orange hair. His outfit is similar to that of Dabura's though a different color, his top being black and his pants being white. He too has a sash, though it goes around his shoulder. Upon transforming, Kogu takes on a green complexion. He loses his black top though oddly enough his red sash still remains. He also wields a sword.


Despite his short film appearance, 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.

In Dragon Ball Legends, Kogu learns of Cabba, Future Trunks and Gohan's battle with Bojack and seeks to avenge his leader by eliminating the three. He ridicules Cabba for his weakness and habit of being saved by others, such as Android 16 and Shallot.


Super Dragon Ball Heroes[]

Supreme Kai of Time Saga[]

Kogu's Bojack Unbound incarnation appears as one of the competitors in the Super Space-Time Tournament, along with his comrades. As a result of his team failing to advance to the second round of the tournament, Kogu and his space-time were erased.

Film Appearances[]

Bojack Unbound[]


Kogu after firing an energy sphere at Future Trunks

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 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.


Kogu killed by Future Trunks

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 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.

Fusion Reborn[]

Along with countless other Dragon Ball antagonists, Kogu makes a cameo appearance when the residents of Hell make their escape to Earth.



In Bojack Unbound, Kogu proved himself a capable fighter by holding his own against Future Trunks.

He is one of the only two Galaxy Soldiers who display the ability to transform. As the second in command, his strength was only inferior to Bojack.

Despite this full power state, he is killed in one piercing blow from Future Trunks in his Super Saiyan Second Grade 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.

Video Games

In the Super Dragon Ball Heroes Prison Planet Saga, Kogu was shown fighting against base Goku, but was easily blasted away by Future Trunks.

Video Game Appearances[]


Kogu card for Dragon Ball Heroes

Kogu makes his debut as a playable character in Dragon Ball Heroes, since the game's second mission.

In Dokkan Battle, Kogu (under his Japanese name Gokua) is available as a unit in both his normal state and his Full Power (Hera Clan) form. Strangely, Tide-Turning Power-Up Gokua, which features Gokua using his Full Power, is not referred to as "Full Power Gokua", despite Bojack being given name distinctions for his base state and his Full Power.

In Dragon Ball Xenoverse 2 after the 1.05.00 version update, Kogu's Clothes appear as a clothing option for the Future Warrior which can be purchased from the TP Medal Shop.

In Dragon Ball Legends, Gokua appears as a playable character added during the 3rd Anniversary Event in 2021. He is playable in his base form and has Full Power (Hera Clan) as a transformation. He also appears as an enemy in Part 11 of the main story.

Voice Actors[]


  • Kogu (Base/Full Power (Hera Clan)) vs. Future Trunks (Base/Super Saiyan)


  • Gokua, his name in the Japanese version, is based off the Japanese word "gokuakuhidou," meaning heinous and inhuman. Bido, his fellow henchman, shares the second half of the word.
    • His name was changed to Kogu in the English-dubbed version, possibly to avoid confusion with Goku.
      • However, he is called Gokua in the English localization of Dragon Ball Legends.
  • Kogu has a similar pseudo-Caribbean accent to Bojack, Bido, and Bujin in the FUNimation dub, although his is more exaggerated. Interestingly, Zangya is the only member of the group not to have a discernible accent in the dub.
  • Kogu is an expert swordsman, just like Trunks. The two also fight each other during the tournament in Bojack Unbound (though Trunks didn't have his sword with him, due to tournament rules).
  • Kogu has a transformation very similar to Bojack's (considering they are of the same race, it is more than plausible that it is the same). His hair also changes and resembles that of a Super Saiyan.
  • Kogu is left-handed.
  • Kogu has a strong resemblance to Crono, the main character of Chrono Trigger, a video game designed by Akira Toriyama.
  • "Kogu" is an anagram of "Goku". Interestingly, the two were seen fighting one another in Super Dragon Ball Heroes' Prison Planet Saga.
