The 2021 Royal Rumble pay-per-view will take over the ThunderDome inside Tropicana Field on Sunday night as WWE will present their first big event of the year.
The Royal Rumble kickstarts the Road To WrestleMania, where the winners of their respective Rumble matches will go on to challenge for a Championship of their choosing.
Whilst there are many WWE stars who have already announced their places in the upcoming Royal Rumble matches, there are others who don't have that benefit.
Sunday night could see the debut of several stars inside the 30-man or 30-woman Royal Rumble matches. These Superstars could be hoping that beginners' luck will be enough to take them to WrestleMania.
#6. Dominik Mysterio could debut in the WWE Royal Rumble match this year
Dominik Mysterio made his official in-ring debut for WWE back at last year's SummerSlam. While Dominik's SummerSlam match proved that the son of Rey Mysterio has a bright future ahead of him, it hasn't propelled him on the main roster in the way many believed it would.
In recent months, Dominik has seemingly been reduced to accompanying his father to ringside for his matches and make up the numbers when needed in feuds with Seth Rollins and King Corbin.
This weekend's Royal Rumble could give Dominik the chance to step out of his father's shadow and show what he can do when he's alone. Rey Mysterio has already made it clear that if his son is in the Royal Rumble match, then he won't hesitate to throw him out, which shows that it would definitely be every man for himself.
Dominik and his father could have some fun spots in the Rumble if they're given the chance to be in the match together. But if the youngster does become one of the surprise entrants then he should be the one to eliminate his father, rather than for Rey Mysterio to shockingly betray his own son.
It's time for Mysterio to pass the torch. Dominik has been by his father's side for a long time and 2021 could finally be the year that he is able to stand on his own two feet and take on everyone inside the WWE ring.
#5. Rhea Ripley could make her official WWE main roster debut at the Royal Rumble
Rhea Ripley could make her debut in the women's WWE Royal Rumble, but she is no stranger to the main roster after her feud with Charlotte Flair led to a one-on-one match at last year's WrestleMania. The Nightmare was sent back down to NXT after WrestleMania 36.
Over the past few months, Ripley has waited patiently for a chance to return to the main roster, and there have been rumors that WWE had plans for the former NXT Women's Champion, which were eventually scrapped.
The Women's Royal Rumble match is fairly new, having only taken place three times previously, which means that many of the current records held in the match could be broken.
Ripley could be the woman to eliminate more than eight Superstars since she has been billed as a dominant force throughout her short WWE career.
At present, it's believed that the former Champion could be set to make her official main roster debut on Sunday night as part of the Women's Royal Rumble match. This could be the boost that the Women's Division has been waiting for.
#4. Lars Sullivan could debut in the upcoming WWE Royal Rumble match
At present, it's unknown as to whether or not Braun Strowman will be in the WWE Royal Rumble match. It's believed that The Monster Among Men should make his return on Sunday night after suffering a knee injury back in 2020, but as of yet, Strowman isn't a confirmed entrant.
With Goldberg busy in the WWE Championship match against Drew McIntrye and Brock Lesnar's WWE status currently unknown, it's unclear if there will be any kind of dominant monster in this year's match.
Lars Sullivan has been taken off WWE TV recently and rumors suggested that this was because WWE wanted to have one main heel on SmackDown whilst Roman Reigns was building his character.
On Sunday night, Roman Reigns will be busy with Kevin Owens in a Last Man Standing match, which means that Lars Sullivan could make his Royal Rumble debut and brush aside much of the competition. It's unlikely that Sullivan will win the match, but stranger things have happened throughout WWE history.
#3. Ronda Rousey could finally appear in the Women's WWE Royal Rumble match
Royal Rumble 2021 could mark the WWE return of Ronda Rousey. Ronda Rousey is just one of a handful of stars who were handed the opportunity to make their official WWE in-ring debut at the WrestleMania pay-per-view, but the former UFC Women's Champion hasn't wrestled in a 30-woman Royal Rumble match yet.
Instead, Rousey has been part of a Championship match which was added to the pay-per-view. After all, Rousey never had to be a part of the 30-woman Royal Rumble bout since she was already the RAW Women's Champion on the Road to WrestleMania 35.
There are rumors that the Baddest Woman On The Planet could be set to make her return at this year's Royal Rumble event and possibly go on to win the match, which would allow her to take part in just her third WrestleMania match.
If so, Rousey could join an elite group of Superstars who were able to achieve such a feat on their debut in the Royal Rumble match, only to then become a top Champion at WrestleMania.
#2. & 1. The Street Profits could finally be part of the WWE Royal Rumble match
This year's WWE Royal Rumble could see the debut of Montez Ford and Angelo Dawkins. Both of them have been part of WWE's main roster for almost two years. But The Street Profits have been solely focused on their quest for Tag Team Championship gold.
The former NXT Tag Team Champions have already proved their worth in the tag team division as former RAW and SmackDown Tag Team Champions, but they have never been given the chance to shine as solo stars.
Ford and Dawkins are popular enough on WWE TV at present that they could be added to the Royal Rumble match as separate entrants, especially since Ford's wife Bianca Belair is expected to dominate the Women's Royal Rumble match.
Montez Ford has a level of athleticism that could stand out in the Royal Rumble match. Ford's impressive sequences would come across as gratifying news for fans if Kofi Kingston isn't able to be part of the match and provide the WWE Universe with their usual entertaining spots.
The competitive field for the Men's Royal Rumble match is already heating up, but there are several places still remaining at the moment. Now that Ford and Dawkins no longer hold the Tag Team Championships, 2021 could be their year to put on an impressive showcase in the Royal Rumble.
