Gokuwmon is a Beast Man Digimon whose name and design are derived from the fictional Son Gokū. It was born from within the boiling magma of Boot Volcano, and pursued strength and extracted modeling data from numerous databases, becoming a Combat Digimon that awakened to the combat instinct it was born with. Although it is journeying across the Digital World to challenge formidable opponents and satiate the craving engraved inside of its heart, if it encounters an opponent that it judges to be strong it will insolently request a battle, regardless of the situation. However, due to the "Kinkoji" (緊箍児? lit. "Tight-bound Child") which was placed on Gokuwmon's head by Sanzomon when it was born, its head will be constricted and it will pass out if it swears to excess, so it reluctantly observes decorum. Gokuwmon is proficient in a large number of martial and magical arts, and since the "Nyoikinkobou" (如意金箍棒? lit. "Ideal Golden-bound Cudgel") in its hand is extensible, it can inflict strikes on enemies that are far away, and is also an all-purpose weapon that can fire a lightning cannon while connected, and fire lightning bullets as pistols when split in two.
Gokuwmon is Sanzomon's student. He tried to stop Betsumon and Gumdramon from causing mischief in the Digital World, but was only able to capture Gumdramon. According to Gumdramon, he is as strong as Shoutmon.
- Higi: Mugen'ei (秘技・夢現影? lit. "Secret Technique: Waking Shadow"): Deftly handles the Nyoikinkobou and makes sport of the enemy with its acrobatic movements, unleashing an attack of afterimages that makes it look like the opponent is under attack by a horde of Gokuwmon.
- Shippū-jinrai Geki (疾風迅雷撃? lit. "Lightning-speed Attack"): Pierces the Nyoikinkobou into the ground and extends it to a thundercloud in the sky, then accumulates the thunder energy within itself, and rams the opponent like a bolt of thunder.
- Choutaiden Raikou Hou (超帯電雷光砲? lit. "Super-electrified Lightning Cannon"): Amplifies and fires the energy within the Nyoikinkobou.
- Kintoun (觔斗雲? lit. "Somersault Cloud"): Gathers clouds and flies through the sky at high speeds.
