After holding the Universal title for 504 days, Brock Lesnar finally lost the belt to Roman Reigns at SummerSlam, which was the third match between the two for the belt in 2018. After Braun Strowman, who defended and retained his Money in the Bank contract match against Kevin Owens, made his way to the ring, his presence ringside played into the hands of Reigns.

Lesnar, who won the Universal championship from Goldberg at WrestleMania 33, defeated Reigns twice this year, once at WrestleMania 34 and another time at the Greatest Royal Rumble.

The Beast, who has signed with the UFC once again and is to face Daniel Cormier for the UFC Heavyweight title, is reportedly signed on for just one more WWE show - the RAW after SummerSlam.

Recent reports have stated that Lesnar wants short-term contracts with both the WWE and UFC. So, how should WWE write off Lesnar from their storylines on RAW?

#1 Lesnar doesn't show up

The biggest bugbear that the WWE fans have against Lesnar's reign as Universal champion is that he never showed up at RAW or PPV shows and defended his title.

It would be ironic and fitting if WWE did not feature Lesnar on the show, stating that the former Universal champion refused to show up at the RAW show at the Barclays Center. They could add more to the storyline by saying that Lesnar did not answer his calls and has gone AWOL and that they would sue him for breach of contract.

This gives WWE the option of restarting the storyline if - and when - Lesnar does return back to the WWE. Vince McMahon or Stephanie/Triple H making the announcement would add more value to the legitimacy of their anger at Lesnar, and WWE could even remove Lesnar's name from their website and social media.

#2 Paul Heyman double crosses Lesnar; attacked by Reigns

In a recent interview with Renee Young, Paul Heyman teased a move to the Roman Reigns camp, if Reigns did beat Lesnar.

Heyman, who has been The Beast's advocate for almost the entirety of Lesnar's career, could be bitter about Lesnar ill-treating him on a show of RAW when the former Universal champion held him by the throat and pushed Heyman to the floor.

Heyman could take retribution for that by aligning with Reigns and the new Universal champion ambushing Lesnar and severely injuring him such that he has to be stretchered out of the arena.

#3 Lesnar is fired by Vince McMahon

On a RAW segment earlier this year, where Roman Reigns was suspended by Vince McMahon, the Chairman of the WWE said that Lesnar may not respect the WWE Universe, and that he does have preferential treatment in the WWE.

WWE could pick up on that storyline and Vince could come out to the ring to make a "special announcement". McMahon could talk about how frustrated and angry he has been with Lesnar and how he hasn't been worth the money that he's paid.

McMahon could then tell Lesnar that he's fired from the WWE, with security coming to the ring to escort him backstage, following which he F-5s McMahon and the security personnel.

#4 Braun Strowman attacks Lesnar

Prior to the match between Reigns and Lesnar, Braun Strowman made his way to the ring and said he would defend his title against Lesnar or Reigns, following their match.

During the match, Strowman, who was standing ring side, bore the brunt of attacks by both Reigns and Lesnar, with Lesnar hitting Strowman with the chair and the Money in the Bank briefcase. The Beast even threw away the briefcase far from Strowman's reach before proceeding back to the ring.

Strowman could not cash-in his Money in the Bank contract as Lesnar ambushed him and left him in no state to compete.

On RAW, an angry Strowman could be shown searching for Lesnar, waiting by the parking lot for the arrival of The Beast, and once he finds him, attack and leave him hurt. This would be a great way to set-up Strowman as a dominant force on RAW, once again.

#5 Locker room gangs up and throws Lesnar out of the door

The WWE locker room can be a united bunch at times, especially when separating two wrestlers brawling in or outside the ring, and this could be another opportunity to show them that they can all come together.

The storyline that can be used here is that they are sick and tired of Lesnar getting preferential treatment and paid the bucks when they're slogging it out most days of the week, on the road and on RAW.

There could be one person who feels that he - and the rest of them - haven't been afforded opportunities due to the presence of Lesnar. Someone like Kevin Owens, can get back in the title picture if he's the one revolting against Lesnar, and starting a coup of sorts, throwing Lesnar out of the building with the help of the rest of the locker room.
