Sheamus/Awesome

Defeating the Great Khali by forcing his way out of the Khali Vice Grip. He overpowered Khali!
Cementing his Heel Face Turn by taking a stand against Mark Henry's recent rampage has to count.
Beating Mark Henry by count out. Not through tricks or anything but by hitting Mark Henry so hard that Henry was out cold for nearly the entire ten count! He became the first person in months to actually beat Henry, let alone in a way that would've been a victory in a Last Man Standing Match! Yes, Mark did beat him up after the match, but only because the defeat resulted in Mark having a Villainous Breakdown.
- More awesome in retrospect, seeing as Henry's been unstoppable by anyone not named The Big Show ever since that match.
His series of matches with John Morrison towards the end of 2010 are generally considered to be the best of either man's career.
Winning the 2012 Royal Rumble by last eliminating Chris Jericho.
- Which led to the anouncement of Sheamus vs Daniel Bryan at Wrestlemania for the World Heavyweight Championship. The dark match opener of last year's Wrestlemania is now one of the main events this year.
  - And then Sheamus proceeded to beat Daniel Byran in eighteen seconds, setting a new record for the quickest World Heavyweight Title change in Wrestlemania history.
Sheamus, along with Daniel Bryan, finally getting time to shine with an instant-classic, show-stealing 2 out of 3 falls match at Extreme Rules. Even more awesome is that Sheamus wrestled a technical match with one of the best tech wrestlers in the world and more than held his own (showing that he's more than the routine power wrestler), even busting out an Texas (Irish?) Cloverleaf.
