The mohawked knockout artist who helped put MMA on the map. Liddell’s power and aggressive style made him one of the most feared light heavyweights of his era.

The Heavyweight GOAT? There’s a strong argument for it. Miocic defended the UFC heavyweight title more times than anyone, beating some of the scariest names in the division. A firefighter by day, heavyweight destroyer by night – what’s not to love?

DJ was like watching a perfectly optimized MMA video game character. His speed, transitions, and submissions were mesmerizing, and his 11 consecutive UFC title defenses at flyweight prove his greatness. Oh, and that suplex-to-armbar submission? Unreal.

DC might be one of the greatest "Plan B" success stories ever. An Olympic-level wrestler, he became a two-division UFC champion, capturing titles at both light heavyweight and heavyweight. His rivalry with Jon Jones hurt his claim as the best ever, but his resume still screams legend.

Khabib was like a bear who learned how to wrestle humans to exhaustion. No one figured out how to beat him. His mauling style overwhelmed some of the best lightweights in the world, and he retired undefeated, leaving everyone wondering what could’ve been had he stayed longer.

The Pride heavyweight GOAT, Fedor was an unstoppable force with an aura of invincibility. Despite being undersized for a heavyweight, he bulldozed through giants, submitting, knocking out, or outlasting them with his trademark stoicism. His run from 2000-2010? Utter dominance.

For a time, Silva seemed almost supernatural. He held the UFC middleweight belt for nearly seven years, delivering Matrix-level knockouts and making world-class fighters look foolish.

A perfectionist inside and outside the cage, GSP dominated welterweights for nearly a decade before taking a four-year hiatus and coming back to win the middleweight title. His wrestling, striking, and fight IQ were second to none, making him one of the sport’s most complete fighters ever. Also, he never lost a rematch – how’s that for problem-solving?

Jones isn’t just a fighter; he’s an unsolvable puzzle. With an 84-inch reach, devastating creativity, and the ability to outwrestle wrestlers and outstrike strikers, Jones reigned over the light heavyweight division like a king who never wanted to give up the throne.

His lone loss? A controversial disqualification. Oh, and he made a successful move to heavyweight. Greatest ever? Hard to argue against it.

Well, that's our take. What do you think? Did we miss anybody?
