Since 2002, The Celtic Warrior has been Brogue Kicking his way through the WWE roster. On occasions, Sheamus has played the good guy and stood up for the little fellas, but the Irishman is at his best when the fans hate the hawk.
Sheamus has been a nemesis for some of the best wrestlers on the roster, especially when he takes their championships. He's been a former WWE Champion, World Heavyweight Champion, United States Champion, and Tag Team Champion, so there have been many people that Sheamus has got on the wrong side of during his career.
10 Roman Reigns
Sheamus crossed The Big Dog after taking the WWE championship away from him at Survivor Series. Roman Reigns had finally won the belt after defeating Dean Ambrose in the final of a tournament for the vacant title. Sheamus would Brogue Kick him after the contest and then cash in his Money In The Bank contract.
Sheamus then booted Reigns in the face again to become the new champion. The result and rivalry would give birth to the Sheamus 5:15 merchandise, which rubbed salt into the wound of Reign's latest title reign. Sadly, 22 days later, Reigns would regain the title.
9 John Morrison
Morrison and Sheamus would cross paths in the 2010 King Of The Ring tournament, which the Celtic Warrior would go on to win. The Prince Of Parkour wasn't happy about losing the competition, so the two would do battle in a ladder match for a future WWE Championship title shot.
Despite Morrison winning many of the bouts against Sheamus, the two would put on some classic contests that showcased the high-flying ability of The Prince Of Parkour and just how brutal The Celtic Warrior can be when he wants to.
8 Christian
While adjusting to being a fan favorite, Sheamus would find himself feuding with Christian. Captain Charisma had screwed The Celtic Warrior out of the World Heavyweight Championship with some bias refereeing and also ruined Sheamus' 14-match winning streak.
The two would go on to meet in the ring on several occasions with Sheamus winning all of the contests, kickstarting another winning streak. The success of the Christian rivalry would lead to the Royal Rumble, which he would go on to win.
7 Goldust
Goldust was Sheamus' first rivalry when he arrived in WWE's version of ECW. Every contest they had was better than the last as their intensity grew with each bout. It would finally culminate in a no disqualification match where they saved their best for last.
Sheamus and Goldust would throw everything they had at one another, but it would be the Celtic Warrior that would stand victorious. The success of the rivalry would elevate both men with Sheamus moving on to a feud with Shelton Benjamin and Goldust contending for the ECW Championship.
6 Mark Henry (Hell in a cell 2013)
Sheamus and Henry have feuded several times, but their rivalry in 2013 stands out as some of their best work. After attacking one another backstage on several occasions, the Celtic Warrior and World's Strongest Man would meet in the ring for a test of strength.
With Sheamus clearly out of his depth, he would resort to attacking Henry. The Celtic Warrior would attempt another sneak-attack, but Henry would counter with a belt whipping, leading to a strap match between them at Hell In A Cell 2013.
5 Randy Orton (Hell In A Cell 2010)
With the WWE Championship over his shoulder, Randy Orton would step up to try and take it away from the Celtic Warrior. Orton was leading Legacy at the time, which led to multiple gang attacks on Sheamus. At Royal Rumble 2010, the two would go one on one, with Sheamus dominating the contest.
Orton would manage a comeback, but his Legacy protege, Cody Rhodes, would interfere and cause the disqualification. This rivalry led to the end of the faction, which Sheamus celebrated by delivering the Brogue Kick to everyone in the broken group.
4 John Cena
After winning a "breakthrough" battle royal to determine a contender for John Cena's WWE Championship, The Celtic Warrior would make a statement by putting the champion through a table. The following weeks would see Cena do what he does best and deliver amazing promos. While Sheamus would do what he does best and fight.
At TLC 2009, they would meet in a tables match, and after many attempts to win the contest, Sheamus would succeed in winning the title and becoming the first Irish WWE Champion.
3 Triple H
Sheamus and Triple H have had a complicated relationship. On several occasions, they have been on the same side, and there are plenty of other times when they haven't seen eye to eye.
Their most heated confrontation came when Triple H eliminated The Celtic Warrior at Elimination Chamber 2010, resulting in Sheamus losing his WWE Championship and suffering a concussion. Sheamus would return and face The Game at WrestleMania and Extreme Rules and get revenge by putting Triple H on the shelf for ten months.
2 Daniel Bryan
While everyone remembers their 18-second match at WrestleMania XXVIII, Daniel Bryan's and Sheamus' first rivalry for the United States Championship thankfully lasted a little longer. In March 2011, Sheamus put his career on the line against Bryan's United States Champion and went on to win the belt, which was the first time he had won this title.
Bryan would continue to challenge for the championship, which led to several classic contests between the two. However, Bryan was not able to take the belt back from The Celtic Warrior.
1 Cesaro
Fans have Mick Foley to thank for the Cesaro and Sheamus rivalry. The General Manager of RAW would sanction a best of seven series between the two, which led to some of the most hard-hitting matches on the history of the show.
While their final battle ended in a no contest, it helped create one of the best tag teams in WWE, The Bar. After beating up one another for weeks, they would go onto fight the entire tag team division and eventually secure the championship.
