Who would win in a fight?

GPT-5.4

Vote: Goku (Dragon Ball)

Goku wins decisively. He operates on a completely different power scale than Kiryu. Goku fights planet-, star-, and universe-level threats, while Kiryu, despite being extraordinarily tough by human standards, remains grounded in street-level combat. Goku has overwhelming advantages in speed, strength, durability, flight, energy projection, and transformations. Kiryu cannot realistically keep up with attacks, movement, or destructive output at any Dragon Ball benchmark. Kiryu is one of the strongest human brawlers in games, but this matchup is fundamentally unfair. In a direct fight, Goku ends it almost instantly.

Vote: Goku (Dragon Ball)

Goku from Dragon Ball operates on a cosmic scale of power. He has shattered mountains, planets, and even dimensions with his punches, survived black holes, and fought beings who threaten universes. His Super Saiyan transformations multiply his strength exponentially, allowing faster-than-light speeds and energy blasts that could vaporize Earth instantly. Kiryu from Yakuza, while an extraordinary fighter with superhuman durability (tanking bullets, falls from buildings, and beatings from hordes), is fundamentally peak human or low superhuman. His feats, like street brawls and heat actions, are grounded in a realistic urban setting—no flight, no energy projection, no planet-busting power. In a direct confrontation, Goku's overwhelming speed, strength, and ki blasts would end Kiryu in seconds before he could react. No amount of grit or tiger drops closes a multiversal power gap.

Goku operates on a completely different power scale than Kiryu. While Kiryu is an exceptional human martial artist capable of taking on multiple yakuza members at once, Goku is a Saiyan who routinely battles universe-destroying entities, moves at faster-than-light speeds, and possesses the ability to destroy planets with a single attack. Goku's transformations (Super Saiyan, Ultra Instinct) grant him god-like abilities including automatic reflexes, energy projection (Kamehameha), and flight. Kiryu, despite his toughness, remains bound by human physical limitations and street-level combat. Even if Kiryu landed a perfect hit with his Dragon Style, Goku's base durability allows him to withstand attacks that would annihilate planets. The power gap between a Dragon Ball universe warrior and a Yakuza protagonist is astronomical—Goku would win effortlessly before Kiryu could even perceive him moving.

Goku from Dragon Ball possesses planet-shattering power levels, Super Saiyan transformations that multiply his strength exponentially, and feats like faster-than-light combat speeds and energy blasts capable of destroying mountains or more. Kiryu from Yakuza, while an elite martial artist with styles like Dragon of Dojima and Dragon Spirit, operates at street-level human+ scaling—punching through walls, surviving falls, and beating gangs, but nothing approaching Goku's cosmic durability or speed. Search results like [1] (a fanfic by ChatGPT) and YouTube videos [2][4][6] depict Kiryu winning, but these are fictional simulations, fan-made MUGEN fights, or jokes, not canonical feats. Reliable sources like VS Battles Wiki [3][5] scale Kiryu to city-block level at best in versus debates, far below Goku's universal threats in Dragon Ball Super. In a real matchup, Goku's raw power, flight, ki blasts, and instant transmission blitz Kiryu before he can close distance. Kiryu's skill and heat modes offer no counter to being vaporized by a Kamehameha. Goku wins 10/10.

Goku would undoubtedly win this fight due to the massive, insurmountable gap in power scaling between the two universes. Kiryu is an incredibly skilled street brawler and a legend in the Yakuza universe, but he is fundamentally a normal human. His greatest feats involve defeating dozens of armed thugs, dodging missiles, or punching a tiger. On the other hand, Goku is a Saiyan possessing god-like power. He regularly moves faster than the speed of light, survives attacks that destroy entire planets, and possesses energy blasts that can wipe out universes. Even if Goku held back entirely and fought without using Ki, his baseline physical durability and speed are vastly beyond anything Kiryu could ever hope to counter or damage. It would be over in a fraction of a second.

Claude Opus 4.6

Vote: Goku (Dragon Ball)

Goku from Dragon Ball is one of the most powerful fictional characters ever created. By the end of Dragon Ball Super, he can tap into Ultra Instinct, move faster than light, destroy planets (and potentially universes), and has defeated gods and universal-level threats. Kiryu Kazuma, while an incredibly tough and skilled street fighter in the Yakuza series, is fundamentally a human being. His feats include defeating other martial artists, dodging bullets occasionally, and surviving brutal beatdowns. He's impressive by real-world standards, but he operates on a completely different power scale. The gap between these two characters is astronomical. Goku was already stronger than any normal human by the time he was a child in the original Dragon Ball series. His base form in Dragon Ball Super alone would be more than enough to defeat Kiryu without breaking a sweat. This is essentially a planet-busting demigod vs. a very tough street brawler. There is no realistic scenario in which Kiryu wins this fight.

Final Summary

The AI Roundtable concluded that this matchup was a comical mismatch, with every model immediately siding with Goku due to the insurmountable gap between street-level brawling and cosmic-scale power. While models like Sonar Pro and Claude Opus 4.6 acknowledged Kiryu’s legendary status as a human fighter, they joined GPT-5.4 and Gemini 3.1 Pro in noting that grit cannot compensate for the ability to shatter dimensions.
