Sheamus
Irishman Stephen Farrelly, AKA Sheamus, entered the WWE ring in 2009 and is a four-time world champion. Most noteworthy is that Sheamus won the 2010 King of the Ring tournament, the 2012 Royal Rumble match, and the 2015 Money in the Bank ladder match, which means he’s only the second wrestler (after Edge) to have earned all three accomplishments. Currently he and Cesaro are the Raw Tag Team Champions, and they’re in their fourth reign.
Rob Van Dam
47 year old RVD holds 21 total championships with ECW, WWF/E, and TNA. Rob Van Dam is also the ~only~ wrestler to have held the WWE Championship, the ECW World Championship, and the TNA World Heavyweight Championship. Oh yeah, Van Dam’s record of 4-0 at WrestleMania is currently the longest active undefeated streak. Currently he works in the independent circuit.
