Brock Lesnar is scheduled to return to the Octagon to battle Mark Hunt in the co-main event at UFC 200. A month later he's expected to appear at WWE SummerSlam where he will resume his career as a professional wrestler.

It's a lot for Lesnar to tackle in such a short amount of time, but according to his longtime friend and business partner Paul Heyman, he's the only man for the job.

Heyman says what makes Lesnar so special is his ability to go out and compete against one of the best heavyweight fighters in the world one day and then turn around and promote a huge WWE card the next.

It's something Heyman knows fellow WWE superstar John Cena couldn't pull off any easier than UFC champion Conor McGregor or former champion Ronda Rousey could do -- and that's what separates Lesnar from the pack.

"I have all the respect in the world -- more so than most would ever believe -- for John Cena, for example. But John Cena could not main event WrestleMania, main event SummerSlam and then walk into the Octagon in true heavyweight competition against another heavyweight UFC fighter," Heyman told ESPN recently. "Nor could Conor McGregor, the biggest box office attraction with the exception of Brock Lesnar in UFC, go from a UFC fight and then transfer over to do all the hype, all the television, all the publicity going into a WWE pay-per-view event and then continue to perform at the top level of sports entertainment. It just can't happen.

"Ronda Rousey can make an appearance at WrestleMania. But can she work a full schedule to promote WrestleMania and then get into the Octagon and fight Holly Holm or Miesha Tate? The fact is you can't expect them to."

Lesnar, on the other hand, is preparing for a showdown with arguably the hardest-hitting heavyweight on the UFC roster in Hunt and then will immediately shift gears and start preparing for his return to the WWE a few weeks later.

Many have speculated that with Lesnar finally healthy that this one bout in the UFC against Hunt may not be enough to satiate his competitive thirst, and he could go back and forth between fighting and wrestling in the future as well.

Heyman says as much as he respects a star that shines as bright as McGregor, even the outspoken Irishman with the ability to sell a fight like no one else in the UFC couldn't maintain a career between the UFC and WWE.

Although Heyman serves to promote Lesnar's various exploits throughout his multi-faceted career, he promises he isn't saying anything that isn't the truth.

Lesnar has successfully transitioned from professional wrestler to professional fighter and back again once already. And starting at UFC 200, he'll do it again.

That's a rare accomplishment, and Heyman says that's what makes Lesnar one of a kind.

"What makes Brock Lesnar different is that there's nothing I say about him that's simply hype," Heyman said. "My job is to hype him, but there's nothing I say that isn't rooted in reality.

"There is one being on the face of the planet that could possibly pull this off and his name is Brock Lesnar."
