Jon Jones ended a three-year sabbatical from the UFC with a convincing win over Ciryl Gane at UFC 285 in Las Vegas.
Considered one of the greatest UFC fighters, Jones has moved up to the highest weight class on his return, and it took him less than a minute into the first round to take Gane to the mat.
The 35-year-old won with a guillotine choke at 2:04 to seal the win.
"When I was a light heavyweight, people would say Jon is a lot stronger than what he appears to be", Jones said.
"Now that I have been powerlifting and living a martial arts lifestyle, I really truly believe I am the strongest heavyweight in the heavyweight division. Some of my best performances are going to be coming in the next few years."
Jones took his time entering the octagon as he played to the sold-out audience because this was his first fight in three years and his first in the heavyweight category.
The former light heavyweight champion said it was important to cement in his own mind that he deserved the mantle of greatest ever.
Jones did exactly that as Tom Brady, another GOAT, looked on. The day of the battle, Brady flew in from Florida and spent time with defensive end Chandler Jones of the Las Vegas Raiders.
"There is no doubt that Jon Jones is special, he is the GOAT. He is undefeated. He has fought all the best competition. Dealing with him is like dealing with an artist," Dana White said.
"I don't know what's going to happen next. I am happy we got to see what we saw tonight. I am a big believer in ring rust. We didn't see any ring rust tonight. He went in there and made it look like nothing. He is a freak of nature, and he is the best ever."
