In the shocker of 2025, massive underdog Koji Ikeda floored the invincible Akihiro Kaneko to secure Upset of the Year.

At K-1 BEYOND, fan-favorite champion Akihiro Kaneko faced the distinct underdog Koji Ikeda in a catchweight bout. Few expected a fighter with a spotty record—having faltered repeatedly against elite competition—to trouble a dominant champion who had virtually cleared out the division. Kaneko entered as a pound-for-pound ranked fighter, undefeated for three years, while Ikeda had lost three of his previous five fights leading up to the match.

The contest’s defining moment arrived just 15 seconds into the opening round, when Ikeda caught Kaneko cold, scoring a shocking knockdown. The champion spent the first two rounds struggling to recover his rhythm—a stark departure from his usual dominance. Although Kaneko rallied in the third, the deficit was too large to overcome, and Ikeda secured the victory via majority decision.

Ikeda and his team capitalized on a technical regression that Beyond Kickboxing analysts had flagged prior to the bout: Kaneko’s abandonment of the jab in favor of head-hunting. Following his grueling trilogy with Masashi Kumura, Kaneko began neglecting his stinging, high-volume jab, adopting a "one-shot" mentality where he kept his hands low, hunting for a single devastating counter.

By abandoning the jab, Kaneko lost his primary tool for distance management. Gone was the stiff jab that acted as a physical barrier; gone was the vision-obscuring probe that made opponents tentative. Instead, fans watched the champion load up and miss, leaving himself open to counters and unable to land power.

This is not to say Kaneko was an easy target. Even in his controversial victory over Riamu Sera, he remained a force to be reckoned with. But while Riamu avoided damage, he failed to exploit the openings to topple the king. Ikeda’s relentless pace, however, proved to be the perfect kryptonite for a champion who refused to jab. The 15-second knockdown wasn't just a flash moment; it was the direct result of Kaneko standing still, waiting for a counter-opportunity that never came.

Ultimately, the King had become a brawler who waited too much, allowing a challenger to dictate the pace. Kaneko lacked the defensive head movement required to sustain this style against a technical, high-volume striker like Ikeda.

As Kaneko admitted post-fight, he had become enamored with the "perfect shot" rather than focusing on the fight itself, forgetting the basics that built his legacy. Koji Ikeda, conversely, knew that if he denied Kaneko the space to think, the champion's technical game would crumble under the volume. In doing so, Ikeda proved the King was mortal and justly earned our "Upset of the Year" honors.

 

HONORABLE MENTIONS

When the opening bell rang, Roman Kryklia wasn't just the favorite; he was an immovable object. But by the fourth round, the "immovable object" could barely move at all. Samet Agdeve’s victory wasn't a fluke knockout or a "puncher's chance" miracle—it was a systematic dismantling of a champion who looked surprisingly unprepared for deep water.

While Kryklia hunted for his trademark headshots, he remained puzzlingly head-heavy, offering almost zero investment in body work to slow the younger man down. Agdeve, meanwhile, fought with a cruel, singular focus on Kryklia’s lead leg. His relentless calf kicks didn't just score points; they acted as a slow-acting poison, eventually anchoring the champion in place.

As Kryklia’s conditioning evaporated in the later rounds, the disparity in preparation became glaring. The man who once ruled the division with an iron fist spent the final ten minutes gasping for air, unable to find the power to turn the tide. Agdeve’s disciplined tactical execution exposed the blueprint to beating a legend, earning him a runner-up spot for Upset of the Year through sheer, calculated grit.
