Brock Lesnar hasn't fought in five years, that doesn't mean he lacks confidence entering the Octagon.

"The Beast" will return to the MMA world for the first time since 2011 when he battles Mark Hunt at UFC 200 this Saturday in Las Vegas. Though it's been a while since he's fought in the cage, Lesnar is betting on himself to emerge victorious.

"The guys that sit in this chair and can give predictions on what they're gonna do and how they're gonna do it, to me they're just blowing smoke," Lesnar told Paul Heyman in a 'Fight Week' interview. "My prediction is, in my heart and my true honest feelings, I'm just going to win. How that happens? I have no idea. I feel well prepared, I'm excited, I'm calm... before the storm, and there will be a storm."

Lesnar, a former UFC heavyweight champion, is returning to the organization in a cross-promotion deal between the WWE and UFC. Vince McMahon's company has used Ronda Rousey in the past and reportedly also has plans to try and utilize Paige VanZant in the future.

After his fight against Mark Hunt, Lesnar will be a major part of WWE SummerSlam on Aug. 21 at the Barclays Center in Brooklyn. His opponent is yet to be determined, but the WWE is using the UFC exposure as a way to hype up "The Beast Incarnate" for their upcoming major spectacle.

Lesnar has been a part-time WWE Superstar since 2012, but hasn't wrestled in the ring since WrestleMania 32 on April 3. As for how he feels training for a real fight in the Octagon, the former WWE World Heavyweight Champion appears ready for the big fight.

"I've had a great camp, I feel great," Lesnar said. "I'm not sitting here trying to fake anything ... I don't have to fake it. I'm coming into the Octagon very well prepared, excited... and that's dangerous. I'll see ya there."

As for Hunt, he previously accused his opponent of being on steroids and was up in arms about the UFC opting not to test him.

"I don't think it's a great move," Hunt told 'UFC Fight Week' on Fox Sports last month. "I think he's juiced to the gills - and I still think I'm going to knock him out. So I don't think that's correct. I don't think he should be allowed to get a four-month exemption otherwise everyone else should. Otherwise I should start juicing. How are you going to clean the sport up doing that s--t? It won't happen. I don't think it's fair."
