#5 Edge (was in multiple factions)
Edge made his WWE debut during the Attitude Era and was a mainstay in the Tag Team division for years on end. Edge initially teamed up with Christian and Gangrel, with the trio dubbing themselves The Brood. They were a part of The Ministry of Darkness, which also consisted of The Undertaker, Viscera, Bradshaw, and a few others.
In 2007-08, during the peak of his run on WWE SmackDown, Edge led a heel faction named La Familia, consisting of Vickie Guerrero, Chavo Guerrero, Zack Ryder, and Curt Hawkins. Back in 2000-01, Edge had a short stint in Team ECK with Christian and Kurt Angle.
Edge's success came as a singles star as well. His first WWE World title win was against John Cena, when he cashed in the Money in the Bank briefcase on him following an Elimination Chamber match. Edge wrestled Cena on various occasions over the next few months, with Lita being on his side. Edge also formed a popular tag team with Randy Orton, called Rated-RKO, and the duo feuded with Triple H and Shawn Michaels for months on end.
