#3 Billy Gunn
Next up on the list is another unlikely name – Billy Gunn. Best knows as one-half of the New Ages Outlaws and as a part of D-Generation X, Gunn’s singles career never really picked up, especially after that fateful segment on WWE RAW where The Rock verbally obliterated him.
Despite his lackluster singles career, Billy Gunn is one of the few Superstars who holds a 100% win record over Cena, owing mainly to the fact that they only wrestled each other in a singles match once. The year was 2003 and Gunn faced Cena in an early King of the Ring tournament match.
Charlotte Flair to return and wrestle a CURRENT CHAMPION?
Thankfully for Gunn, The Undertaker interfered during the match to cost Cena, helping Billy Gunn pick up the win over Cena. The duo never wrestled each other in a singles match after this again meaning that Gunn is in the list of rare opponents in WWE who Cena has faced by never beaten.
Billy Gunn worked in the WWE Performance Center briefly after retiring and is currently signed to All Elite Wrestling as a road agent and producer.
