The UFC thrives on controversy. Whether it’s heated rivalries like Conor McGregor vs. Khabib Nurmagomedov, shocking interviews, or off-the-wall social media antics, fighters often find themselves in the crosshairs of both fans and critics. Some are loved for their brash personalities. Others? Not so much.

Today, we take a look at five UFC fighters who have managed to stir up the most controversy. From Bryce Mitchell’s history-rewriting podcast to Colby Covington’s personal digs, these fighters have often found themselves at the center of heated debates and under fire from the fandom!

1. Bryce Mitchell

Bryce Mitchell has always been outspoken, but his latest comments may have pushed the limits of free speech into dangerous territory. In the debut episode of his ‘ArkanSanity Podcast’, Mitchell made shocking remarks defending Adolf Hitler, questioning the Holocaust, and making even more controversial remarks.

If that wasn’t enough, at one point he even suggested that the German leader was “a good guy” who “fought for his country.”

The backlash was immediate. Mitchell’s social media exploded with criticism, forcing him to backpedal. In a public apology, he wrote, “I know that a lot of people died in the Holocaust, and that’s a fact. Hitler did a lot of evil things, I think we can all agree on that.” But for many, the damage was already done.

2. Colby Covington

Colby Covington thrives on being the villain. Whether it’s political rants, personal jabs, or over-the-top antics, ‘Chaos’ rarely holds back. But even for him, his remarks about Leon Edwards’ father at the UFC 296 press conference crossed the line.

On stage, Covington smirked and told Edwards, “On Saturday night, I’m going to bring you to a place you never want to be. I’m going to bring you to the seventh level of hell. We’ll say what’s up to your dad while we’re there.” A disgusting low blow, considering Edwards’ father was tragically murdered outside a nightclub when the former UFC champ was just 14.

The insult sent Edwards into a rage—throwing a water bottle at Covington before security intervened. Fans were quick to call Covington out, labeling his trash talk as disrespectful and cruel. But for Covington, it was just another day at the office. After all, he knows controversy sells.

3. Jamahal Hill

Jamahal Hill’s rivalry with Alex Pereira started in the cage but quickly spiraled into something uglier. After being brutally knocked out at UFC 300, Hill accused Pereira of influencing the referee. He insisted he wasn’t making excuses, but his constant complaints painted a different picture. “That happened, and next thing I know, m—– is right in my face and he caught me,” he admitted.

Pereira, known for his stoic demeanor, didn’t need words to respond. His now-iconic Khaby Lame-inspired hand gesture became an instant meme, and the internet ran with it. Suddenly, Hill wasn’t just a fighter online—he was a walking punchline.

Then, things took a disturbing turn. Hill revealed that trolls had started harassing his 9-year-old daughter with vile messages. “That really p—- me off,” he confessed. The internet loves a good joke, but when does it go too far? Hill might have fueled the fire, but his family never signed up for the flames.

4. Conor McGregor

If there’s one fighter who thrives on controversy, it’s Conor McGregor. But even ‘The Notorious’ isn’t immune to internet backlash. Case in point—his bizarre tweets about Kylie Jenner. After stumbling across a fan-made collage of the reality star, McGregor posted, “If real, we convert! #McGregorKardashianFamilyTree.” As if that wasn’t strange enough, he followed it up with, “#MyCousin.” Fans were left scratching their heads. Was it a joke? A drunken tweet?

Beyond his social media antics, McGregor also made headlines for his odd encounter with Jake and Logan Paul. Despite years of trash talk, he was seen rubbing shoulders with the YouTubers on their way to Donald Trump’s presidential inauguration. He even joked about slapping both of them, plus KSI, calling them “side jobs.”

Even during the build-up to his UFC 229 clash against Khabib Nurmagomedov, ‘The Notorious’s questionable antics had led to a lot of fans turning against the Irishman.  Even now, for a man who once held two UFC titles simultaneously, McGregor seems more interested in social media spats than fighting these days. Is he trolling the world, or is the world finally trolling him back?

5. Israel Adesanya

Israel Adesanya’s UFC career has been a rollercoaster of championship wins and public scrutiny. While he’s no stranger to controversy, nothing has stuck to him quite like the infamous dog video incident.

It all started when Sean Strickland, never one to hold back, called out Adesanya for alleged inappropriate behavior with his late pet dog. Strickland even suggested that ‘The Last Stylebender’ should be investigated by PETA. The comments gained traction, and soon, the internet was buzzing with memes and accusations.

Fast forward to UFC 305’s press conference, and Dricus Du Plessis saw an opportunity to reignite the flames. When Adesanya asked, “When did I become the underdog?” Du Plessis shot back, “Nobody said anything about dogs, bro. Chill out.” Adesanya, visibly annoyed, forced a laugh.

The former champ defended himself, calling the claims ‘entertaining lies’ but the damage was done. Whether fair or not, the internet never forgets. And the fans take every opportunity to remind him of the same.

In the end, love them or hate them, these fighters have one thing in common—they keep fans talking. Some thrive on the controversy, using it to sell fights. Others find themselves trapped in scandals that refuse to go away. But here’s the real question—does being the most hated fighter hurt a career, or does it make them even bigger stars?
