#2 Evolution (Every member won a World title)
In late 2002, Triple H formed an alliance with the legendary Ric Flair and the duo soon brought in two young guns, Randy Orton and Batista. The quartet was dubbed Evolution, referring to the fact that it was an association between the past, present, and future of WWE.
The dastardly faction wreaked havoc on the WWE roster for around two years, before Orton was kicked out following his World title win over Chris Benoit at SummerSlam 2004. Batista went on to turn on Flair and Triple H and became World Champion at WrestleMania 21. Both Batista and Orton were mainstays in WWE for the next several years.
While Batista's popularity bagged him several major roles in Hollywood, Orton carved a legacy for himself in WWE that would be hard to replicate in the future. Triple H was the top heel on RAW during Evolution's peak and held the World title on numerous occasions. As for Flair, he is a 16-time World Champion and his record is only equalled by WWE legend John Cena.
