Not every WWE Superstar can say that they have done almost everything they had to do in the company. They may win the Royal Rumble and Money in the Bank, but everything would be futile if they didn't get their hands on the big championships. A select few Superstars managed to get their hands on not one but almost every championship they could win, and they are called the Grand Slam Champions.RELATED: Nick Aldis & 9 Other Wrestlers Who Were Champions For Over 1000 DaysUnder the current format, the criteria for a WWE Superstar to get recognized as a Grand Slam Champion is they have to win either the WWE or Universal Championship, both the Intercontinental and United States Championship, and either the Raw or SmackDown Tag Team Championship. As far as the women's division is concerned, the Superstars have to win the Raw, SmackDown, and NXT Championship, and the WWE Women's Tag Team Championship.a

10 Shelton Benjamin

Shelton Benjamin needs to win the big one to immortalize his name among the WWE Grand Slam Champions. Benjamin was highly successful in the mid-card and tag team division during his first run with the company.

He's a former three-time Intercontinental Champion, three-time Raw Tag Team Champion, three-time 24/7 Champion, and one-time United States Champion. He needs to win either the WWE or Universal Championship to become a Grand Slam Champion.

9 Dolph Ziggler

Dolph Ziggler is one of the most decorated Superstars in WWE history. Despite Ziggler having two reigns with the World Heavyweight Championship, WWE does not acknowledge him as a Grand Slam Champion, as they no longer consider the title as an acceptable criterion to get the distinction.

Aside from that, he's also a six-time Intercontinental and two-time United States Champion. He has also held the Tag Team Championship four times. He needs to win the WWE or Universal Championship to get his name inked on the list of WWE Grand Slam Champions.

8 Rhea Ripley

With Bayley becoming the first female Grand Slam Champion in WWE, the list also includes Asuka, Sasha Banks, and Charlotte Flair. Rhea Ripley is in close pursuit to get her name on the list, and she needs to win the SmackDown Women's Championship to complete her collection.

Ripley is a former NXT Women's Champion and NXT UK Women's Champion. She has won the WWE Women's Tag Team Championship along with Nikki A.S.H., and won the Raw Women's Championship from Asuka at WrestleMania 37. She has ample amount of time to complete her grand slam and could win the SmackDown Women's Championship in the near future.

7 Alexa Bliss

WWE's Goddess, Alexa Bliss, is one of the most decorated Superstars in the company's women's division. She's a former three-time Raw Women's Champion, two-time SmackDown Women's Champion, and has held the WWE Women's Tag Team Championship on two occasions with Nikki Cross.

She has to win the NXT Women's Championship to complete her collection and get her name among the list of Grand Slam Champions. She could follow Charlotte Flair's footsteps and challenge for the NXT Women's Championship despite being a member of the main roster once she comes back from her hiatus.

6 Shinsuke Nakamura

In a perfect world, Shinsuke Nakamura would already be a Grand Slam Champion, but he got stuck in the wrong reality where he's floundering in the mid-card.

The King of Strong Style is the current Intercontinental Champion, in his second reign. He is also a former two-time United States Champion, and two-time NXT Champion. He has held the SmackDown Tag Team Championship with Cesaro on one occasion. He needs the WWE or Universal Championship to complete the grand slam, and that could still happen if WWE has some faith in Nakamura.

5 Bobby Lashley

The Almighty Bobby Lashley is having the best WWE run of his career, and he has a strong chance of reclaiming the WWE Championship. Aside from his reign as WWE Champion, Lashley has two reigns each with the Intercontinental, United States, and ECW Championship.

He needs to win the Raw or SmackDown Tag Team Championship to complete his grand slam. He has the perfect opportunity to do that with his Hurt Business partners MVP, Cedric Alexander, and Shelton Benjamin, and we could see The Almighty's name among the list of Grand Slam Champions very soon.

4 Drew McIntyre

The Scottish Warrior has been on a roll ever since he became a two-time WWE Champion. He now has his sights set on the Universal Championship and might have to overcome some authority conspiracies to get his shot at the title. Aside from his two WWE Championship reigns, Drew McIntyre has held the NXT and Intercontinental Championship on one occasion, and has two reigns as a Tag Team Champion.

All he needs is the United States Championship to become a Grand Slam Champion. However, it might take some time as he's on SmackDown and the US title is exclusive to Raw. Unless he gets drafted to Raw or the US Champion comes to SmackDown, it might take some time for him to get his hands on the title.

3 John Cena

With over sixteen World Championships and other accolades, including two Royal Rumble wins, John Cena has achieved almost everything in his WWE career. The only achievement that has been evading Cena is the Grand slam distinction, as he needs one more title to get his name on the list.

Aside from the World titles, John Cena is a five-time United States Champion and a four-time Tag Team Champion. He just needs to win the Intercontinental Championship to complete his grand slam. However, in this stage of his career, the chances of Cena winning a mid-card title might be entirely off the cards, and we might never see his name on the list of Grand Slam Champions.

2 Big E

After over a decade in WWE, Big E is finally getting his due with a reign as the current WWE Champion. He might have started green but picked up steam once he joined Kofi Kingston and Xavier Woods to form The New Day. Before winning the WWE Championship, Big E won the Tag Team Championship eight times. He is also a former 2-time Intercontinental Champion.

He needs to win the United States Championship to complete his grand slam, and the chances of that happening are alive, as the US title is also part of Raw, sp we could see him winning that championship in the future.

1 Kevin Owens

Kevin Owens has his sights set on the WWE Championship, and with the rumors of him leaving WWE once his contract expires, we could very-well see the promotion put the WWE title on him in an effort to make him stay. However, if KO decides to leave, he will also leave behind the opportunity to become a Grand Slam Champion.

With Owens already being a former Universal Champion, NXT Champion, three-time United States Champion, and two-time Intercontinental Champion, he just needs a Tag Team Championship to complete his collection and become a Grand Slam Champion.
