#2 John Cena (Royal Rumble - January 27, 2008)
John Cena tore one of his pectoral muscles performing a hip toss in 2007 and was supposed to be out of action for up to a year. Cena, being superhuman, returned in four months and shocked the holy heck out of everyone in Madison Square Garden, as his music hit and he became the 30th and final entrant in the 2008 Royal Rumble match.
Just over eight minutes later, John Cena was the number one contender for Randy Orton’s WWE Championship.
It wasn’t even rumoured that he would show up. This return was an amazingly well-kept secret, which was incredibly difficult to do by that point with the massive reach of the internet. It happened, free of speculation, rumour or otherwise, and it was one of the greatest, and definitely one of the most shocking, returns in the history of WWE.
