Top 5 Anthony Joshua fights that defined his boxing legacy

Few fighters in the modern era have captured the world’s attention quite like Anthony Joshua. An Olympic gold medalist and two-time unified world heavyweight champion, AJ has cemented a legacy built on extraordinary knockout power, speed, and technique. His career has been anything but a straight line — marked by stunning upsets, emotional comebacks, and moments of pure brilliance — and that’s exactly what makes it worth revisiting in full.

Here are the five fights that defined everything.

5. Joshua vs. Charles Martin — The Night a Champion Was Born

Charles Martin may have been the defending IBF world heavyweight champion walking into the O2 Arena that night, but the gulf in class was obvious from the opening bell. Joshua had Martin on the back foot immediately, finding consistent success with his right hand throughout the first round. In the second, he landed a flush shot that put Martin on the canvas within the opening 60 seconds. Martin answered the count but was immediately dropped again by another explosive right hand, and the referee waved it off. It was the moment the heavyweight world truly took notice — a star had arrived.

4. Joshua vs. Wladimir Klitschko — The Greatest Night of His Career

In one of the most anticipated bouts in recent memory, Joshua faced the legendary Wladimir Klitschko at Wembley Stadium in front of 90,000 fans. Winning with an 11th-round TKO after being knocked down himself earlier in the fight, AJ demonstrated heart, composure, and finishing instinct all in one night. Sold-out Wembley, heavyweight danger, recovery under fire, then a breathtaking finish — this remains the defining performance that made him feel truly inevitable on the world stage.

3. Joshua vs. Andy Ruiz Jr. II — The Redemption Fight

After suffering one of the most shocking upsets in boxing history in their first meeting, Joshua traveled to Diriyah, Saudi Arabia for the rematch with everything on the line. A more controlled, disciplined version of AJ emerged — less chaos, more ring intelligence, and a clear game plan executed to perfection. He reclaimed the WBA, IBF, and WBO heavyweight titles via unanimous decision, silencing doubters and proving that great fighters are defined not by the fall but by how they rise back up.

2. Joshua vs. Joseph Parker — The Tactical Masterclass

Joshua unified the WBA, IBF, and IBO heavyweight titles by defeating Joseph Parker via unanimous decision at the Principality Stadium in Cardiff — his first professional bout to go the full twelve rounds. It silenced critics who claimed AJ could only win by knockout, showcasing a more patient, ring-intelligent version of the champion. It was a mature, measured performance that revealed a fighter still evolving at the highest level.

1. Joshua vs. Francis Ngannou — The Statement Win

In a fight that reminded the world what his power looks like at its most precise, Joshua took out Ngannou with a crushing KO finish in Round 2. The former UFC heavyweight champion had previously knocked down Tyson Fury and arrived with legitimate knockout credentials of his own — but AJ was ruthlessly efficient from the first exchange, delivering one of the most emphatic and clean performances of his later career. It was a statement win at a time when his legacy needed exactly that.

A Legacy Still Being Written

Anthony Joshua’s story is far from finished. The highs of Wembley, the heartbreak against Ruiz, the back-to-back losses to Oleksandr Usyk — all of it has shaped a career that refuses to follow a simple script. What these five fights prove, above all else, is that AJ at his very best belongs in any serious conversation about the greatest heavyweights of his era.

• Career record— 29 wins, 4 losses, 26 KOs
• Two-time unified heavyweight champion
• 2012 Olympic gold medalist in the super heavyweight division
• Held the WBA, IBF, WBO, and IBO titles simultaneously

Whether his best days are behind him or still ahead, one thing is certain — Joshua has already secured his place in boxing history.
