A former UFC Heavyweight Champion, Brock Lesnar is the real deal. He's been the WWE's top star for the last few years, headlining the company's biggest shows despite only wrestling a few times a year.
He's been the top dog since 2014, when he ended The Undertaker's 23-year WrestleMania winning streak. He's been WWE Universal Champion since 2017's WrestleMania, where he toppled wrestling legend Bill Goldberg.
Although Brock Lesnar has been WWE's special attraction in recent years, the weight of the pro wrestling industry has mostly been on John Cena's shoulders for the last decade.
Cena is known as "the face" of the WWE, one you'll see on posters, merchandise and TV shows everywhere. With that responsibility comes some serious spoils: Cena is a 16-time WWE Champion and banks about $10 million a year for his grappling duties.
Roman Reigns is the most controversial wrestler today. Fans consider him the chosen one, groomed by the company to take Cena's place as the next face. The problem is, many fans have rejected him for this reason, feeling as though Reigns' ascent to the top has been too manufactured.
He's positioned as a top good guy, but you'll often hear him showered with boos by the TV audience. But Reigns is a great athlete, looks like a star and often has killer matches, so expect to see him a lot.
AJ Styles is the best performer in the WWE today. A former star of companies like TNA and New Japan Pro Wrestling, it took AJ 15 years to get to the WWE, but his finesse and spectacular offense is unmatched in the company.
He made his debut in January 2016 and has had countless great matches since. He also became the WWE Champion in just eight months, among the quickest to ever capture the prestigious title, which means WWE officials are very aware of just how good he is.
Ronda Rousey is arguably the biggest mainstream star in the WWE -- and she hasn't even wrestled yet.
After first appearing at the Royal Rumble back in January, the former UFC megastar will have her first match at WrestleMania 34. She'll be teaming up with Kurt Angle to take on Triple H and Stephanie McMahon.
Triple H is in the twilight of his wrestling career, grappling only a few times a year. But he's bigger than ever -- literally, look at those guns -- and looks to be in one of the headlining matches at this year's WrestleMania.
The 14-time world champ has moved to a behind-the-scenes position in recent years, becoming the 2IC behind CEO Vince McMahon. When he shows up in front of the camera, it's usually a pretty big deal.
Shinsuke Nakamura was one of Japan's biggest wrestlers until he made the jump to the US in 2016.
Since then he's dazzled the WWE audience with his unique charisma and martial arts-inspired offence. He has the biggest match of his career at WrestleMania, where he'll face AJ Styles for the WWE Championship.
In the past few years, WWE have made women's wrestling matter. The female performers went from getting the "bathroom break" spot -- that is, given a few minutes to wrestle in between big matches -- to being headlining acts.
The woman leading the pack is Charlotte Flair, daughter of the legendary Ric Flair. One of the company's best athletes, Flair is a multiple-time women's champion and made history in 2016 when she and Sasha Banks became the first women to main event a WWE pay-per-view.
The Undertaker is 28 years into his WWE run. 28 years.
It all appeared to have ended at WrestleMania 33, where he suffered a loss to Roman Reigns -- only his second loss ever at a WrestleMania. But, once again, The Deadman will rise at the Show of Shows, this time to take on John Cena.
If AJ Styles is the WWE's best wrestler, Seth Rollins is hot on his heels. Explosive, high-flying and silky smooth, Rollins has become one of the company's most versatile performers -- both in and out of the ring.
After a stint in the tag-team division, Rollins got everyone's attention in February when he wrestled for over an hour and beat Roman Reigns and John Cena in two separate matches, one after the other.
