Okay, so the other day I was thinking about boxing, you know, just randomly, and a question popped into my head: Who beat the most world champions in boxing? Sounds simple, right? But trust me, it wasn’t.
First, I jumped straight into the internet, hoping to find a quick answer. I typed in “who beat the most world champions in boxing” and started scrolling. At first, all I got was general boxing stuff, like who’s the greatest of all time, not exactly what I was looking for.
I started seeing names like Floyd Mayweather and Julio Cesar Chavez, those guys are legends, so I thought they’d be at the top of the list. I started clicking on articles and reading about their records. Floyd’s known for being undefeated, which is crazy impressive, but that didn’t really answer my question about beating the most champs. Then there’s Julio Cesar Chavez, who apparently has had 37 world title fights! That’s a ton of fights, and I thought, “Maybe he’s the guy?”

- So, I started digging into Chavez’s record.
- I spent hours on boxing forums and websites, trying to find a list of all the champions he beat.
Then, a name that kept coming up was Manny Pacquiao. This guy has won titles in eight different weight divisions. Eight! That’s nuts. I figured he must have fought a lot of champions to win all those titles. I started to think, “Pacquiao might be the one who beat the most world champions.”
I dove deeper into Pacquiao’s career, trying to see how many champions he actually faced. It was tough because there were so many fights to go through, and not all of them were against champions. And then, I came across some old-school names, like “Walker Smith Jr.” Turns out that’s Sugar Ray Robinson’s real name. I found out he fought from the 40s to the 65s. But there was no clear answer if he beat the most world champions.
I even read about Len Wickwar who had 342 wins. 342! But again, no concrete answer to my initial question about beating world champions.
I also read about a boxer who beat champs in lightweight, middleweight, and even heavyweight divisions back in 1903. That’s like, over a century ago! Boxing was so different back then.
I found out about Miguel Cotto too, he’s a four weight class champion. So I went down that rabbit hole for a bit, but still couldn’t find a clear answer about who beat the most world champions.
After hours of searching and reading, I felt like I had a bunch of puzzle pieces but no clear picture.

The Conclusion
So, here’s the thing: From what I found, Manny Pacquiao seems like a strong contender for the title of “the boxer who beat the most world champions” because he’s won titles in eight different weight classes. But honestly, it’s tough to say for sure because boxing records are complicated. There are a lot of great fighters out there, and it depends on how you define “beating a world champion.”
In the end, I realized that boxing history is way more complex than I thought. It’s not just about who won the most fights, but who they fought, when they fought, and how the sport has changed over time. I still don’t have a definitive answer to my question, but I learned a ton about boxing along the way. It was a wild ride, but that’s what makes it fun, right?
You never know where a simple question will take you!
