5 Major changes that could happen after Brock Lesnar's WWE Title win at Day 1: 2 changes to WrestleMania main events, Surprising star to win Royal Rumble?

The Day 1 show is officially over and Brock Lesnar is the new WWE Champion. It's still hard to imagine that Lesnar, who was scheduled to headline the show against Roman Reigns, is now the champion of the opposite brand.

In the process, he has become a six-time WWE Champion and a nine-time overall world champion in the company. The fallout of The Beast Incarnate's title win is huge, and these are the changes that could be made going forward:

#5. Brock Lesnar to get a new opponent for WrestleMania 38?

Brock Lesnar was reportedly penciled in to headline WrestleMania 38 against Roman Reigns at Night Two. However, that could see a big change because of the most important superstar in the company testing positive for COVID-19.

Day 1 marked the first time that Lesnar and Bobby Lashley shared a ring. While many fans were excited about the face-to-face meeting they would have, that actually didn't happen.

We saw The All Mighty get more offense on Brock Lesnar this time around, and it was Big E who took the fall. Lashley stood outside the ring distraught as he came close to the WWE title, but the man added to the match a few hours before walked out with the title instead.

There was a moment where Bobby Lashley stared down at The Beast Incarnate, and that was possibly a bigger tease of the match then we have ever seen before.

Lashley mentioned a few years ago that the reason he returned to WWE was to get a match against Lesnar. While he defeated Roman Reigns clean in 2018, he lost a rematch that eventually led to The Tribal Chief dethroning Brock Lesnar at SummerSlam that year.

Bobby Lashley expressed his frustration over that situation, stating that he fully expected to face The Beast Incarnate at SummerSlam that year. The timing would have been right and it still makes no sense that the first Reigns-Lashley match didn't have a number one contender's spot at stake.

Bobby Lashley fully deserves the match against Brock Lesnar, and his run from the pandemic era in 2020 until now has been nothing short of impressive. One could even argue that he was a better WWE Champion than Big E, or at least he was presented as a more legitimate one.

The tease at the end of Day 1 could very well lead to Lesnar vs. Lashley at WrestleMania 38.

#4. Roman Reigns gets another opponent at WrestleMania and not Brock Lesnar

As mentioned before, the originally planned main event of WrestleMania 38 Night Two was Roman Reigns vs. Brock Lesnar. While Reigns picked up the win over Lesnar at Crown Jewel, something different may have been planned for Day 1.

The storyline, heavily-involving Paul Heyman could have potentially seen a finish that would continue the multi-match series until WrestleMania at the AT&T Stadium. However, Roman Reigns' positive COVID test has had rippling effects, and the match against Brock Lesnar might be scrapped or delayed.

Instead, there has to be a new contender from SmackDown. As of this writing, the only person who fits the bill for that is Drew McIntyre. Reigns has run through SmackDown and has taken out top contender after top contender, including the likes of Edge, Daniel Bryan, Kevin Owens, John Cena, etc.

McIntyre is the only credible opponent for The Tribal Chief at WrestleMania right now, and AT&T Stadium could be the place where we finally see the end of Roman Reigns' soon-to-be record-breaking reign as Universal Champion.

However, there's always the possibility of WWE wanting Reigns' run to continue, which means that Drew McIntyre could lose his second WrestleMania world title match in a row. That might damage him a lot more than a loss would damage Roman Reigns - but this too is up for debate.

#3. Big E wins the Royal Rumble after losing to Brock Lesnar?

Brock Lesnar pinned WWE Champion Big E to take the title from him. He has ended the world title reigns of two New Day members now, and Big E could only enjoy a title reign of three months.

It was an interesting choice as the company could have easily had Lesnar pin Seth Rollins or Kevin Owens if they wanted to protect Bobby Lashley. Big E's first WWE title reign will likely be viewed as an underwhelming one, as the promotion could have done better to present him as a legitimate champion.

He wasn't made to look good in his title reign, but that only confirms the general sentiment that WWE knows how to book heels far better than babyfaces in the modern era.

However, Big E losing the title doesn't necessarily mean that he can't win it again, or that there aren't any big plans for him. WWE intentionally split him from The New Day in the 2020 Draft and kept them on separate brands later in 2021 despite their brief reunion on RAW.

Big E could now become one of the favorites to win the Royal Rumble, where he too, can be a legitimate challenger to Roman Reigns if handled right.

#2. Big E to possibly lose his push after title loss to Brock Lesnar?

Big E's title loss to Brock Lesnar could have negative consequences. While the previous slide looked at the potential positives that could come out of E dropping the WWE title to Lesnar, this one is a bit grimmer.

Big E is certainly not old, and with the careers of top superstars extending significantly this generation due to better diets, lifestyle choices, and exercise routes, the now-former WWE Champion may have many years to go.

However, it's also possible that the peak of his career is now over. Hopefully, he isn't treated like Kofi Kingston, who lost the WWE title to Brock Lesnar in ten seconds and was simply inserted back to The New Day's tag team title picture instead of pursuing the world title he spent a decade to chase and win.

Big E could lose his push after Lesnar's WWE title win, and if so, he might only be restricted to an upper-card superstar. Hopefully, that doesn't happen.

#1. A world title unification match between Roman Reigns and Brock Lesnar at WrestleMania?

Roman Reigns vs. Brock Lesnar at WrestleMania 38 could still happen. But this is one scenario we certainly don't wish for at all. This scenario involves WWE booking a world champion vs. world champion match at The Show of Shows, with the winner then defending on both brands.

This isn't a good idea at all. The company still has a big roster that is split over two brands - and that is a system that benefits fans and the talent. More superstars are allowed opportunities, and having only one world champion now would severely restrict one brand or the other.

WWE is also being paid good money by both FOX and the USA Network for their broadcast deals, so it makes sense to keep two world titles. Lesnar will likely stick on RAW, and hopefully, there isn't a scenario where the feud with Reigns continues.

With that said, the only issue this causes is that the intense rivalry between Roman Reigns and Brock Lesnar could now abruptly end without much of an explanation.
