Members: Triple H, Shawn Michaels, Chyna, Tori, X-Pac, Kane, Road Dogg, Billy Gunn, "Ravishing" Rick Rude (First Manager), and Jim Neidhart (For one whole night can you believe it).
As we all know Triple H, Shawn Michaels, Chyna, and Rick Rude (Manager) were the original members until Rude's departure later on due to health. D-X is generally considered one of the most popular stables in pro wrestling history.
The group's original run was from 1997 to 2000, undergoing several roster changes during that time. After on-off returns in 2000 and 2002, D-X reformed in June 2006 as the duo of Triple H and Shawn Michaels.
D-X has been believed to be heavily influenced by WCW's nWo (although Vince McMahon has denied this on many occasions), and was created to battle with WCW in the ratings war, and who can ever forget the D-X invasion of WCW, which to this day stands as one of the top 10 moments in wrestling/RAW history.
Back in 1998, Steve Austin was bringing the WWF into the attitude era. But right behind him was the stable D-Generation X. After Shawn Michaels left due to injuries; Triple H recruited X-Pac, Road Dogg, and Billy Gunn to revitalize the stable.
Their devil-may-care attitude won them the respect of the fans; and they feuded with Owen Hart, The Rock, and Vince McMahon and his stable the corporation.
Their top moment was when they made attacks on the World Wrestling Federation's top rivals WCW. While the stable broke up at the start of 1999, they would come back together months later, but with less success than before.
Still, the way they helped the attitude era is what people remember them for.
