WWE Royal Rumble 2018: 5 Surprise entrants that could shock the WWE Universe

#4 Christian

Christian was WWE's longest-reigning ECW Champion.

Christian helped revolutionize the tag team division alongside his partner Edge. Their match at Wrestlemania 2000 against the Hardy Boyz and Dudley boyz was epic. It is this match that led to the creation of the Tables, Ladders, and Chairs match.

Christian is the only wrestler to have held the NWA, ECW, and World Heavyweight Championships. He won the World Heavyweight Championship when he defeated Alberto Del Rio at the 2011 Extreme Rules pay-per-view event. He later had great matches with Randy Orton for the World title. Christian's final match took place on the March 24th episode of Raw where he won a fatal four-way match against Alberto Del Rio, Dolph Ziggler and Sheamus to challenge Big E for the WWE Intercontinental Championship.

A special appearance at the Royal Rumble would make the fans at the Wells Fargo arena erupt. It has been almost four years since Christian competed inside a WWE ring. A "kill switch" move on any of the other 29 competitors would be nostalgic and a moment to remember.
