Roman Reigns is unstoppable right now, and after beating Brock Lesnar to retain the WWE Universal Championsho[p at Crown Jewel last night, it doesn't seem like he'll be losing the title anytime soon.

Roman Reigns has been Universal Champion for 418 days now, and will certainly be eyeing up Brock Lesnar's record of the longest-reigning Universal Champion.

Brock Lesnar's longest reign as Universal Champion lasted 504 days between April 2017 to August 2018, meaning Reigns is just 87 days from topping that record.

Roman Reigns reign as Universal Champion, after winning the title at Payback last year on August 30, will reach 505 days on January 17, 2022.

This means that should Roman Reigns still be the Universal Champion at the Royal Rumble on January 29. 2022, he'll walk into the show as the lognest reigning Universal Champion.

Brock Lesnar is also the Superstar with the most combined days as champion throughout all of his reigns, with his three reigns lasting a combined 686 days.

That'll also be a record that Roman Reigns is targeting, with 'The Tribal Chief' having 481 days as champion across his two reigns in 2018 and 2020-21. 

Reigns has a bit longer to go to break that record, as the Universal Champion will have to hold his title for another 206 days before he breaks Lesnar's record.

To be recognised as the person with the most combined days as Universal Champion, Roman Reigns will have to hold the title until May 16, 2022.

This means that Roman Reigns will have to walk out of WrestleMania 38 in Texas on April 3, with Drew McIntyre, The Rock and the aforementioned Brock Lesnar potential opponents. 

There have even been rumours to suggest that Roman Reigns is going to face The Rock at WrestleMania 39 on April 2, 2023, and if he hasn't dropped the title before then, he'll have been champion for 945 days.

At that point, should he have not dropped the title between now and April 2023, Roman Reigns will have spent a staggering 1008 days as Universal Champion combined across his two reigns.
