#20 D-Generation X
We use to think that nWo would take over the WcW, well D-Generation X ACTUALLY did take over the WWE. I'm not saying that this happened on camera but behind the scenes.
DX started off featuring Triple H, Shawn Michaels, Rick Rude, and Chyna. They were vulgar and unapologetic. They made a mockery of their competition and pushed the boundaries of what was allowed on wrestling television.
After Shawn left the company, Triple H retained control of the group and rebuilt it featuring the New Age Outlaws (Road Dogg Jesse James and Bad Ass Billy Gunn) and X-Pac (Triple H's old friend that just left the nWo). They invaded Monday Nitro with military reinforcement and became a dominating force in WWE.
While nWo was able to make a huge impact on WCW, D-Generation X was able to have just as much of an impact on WWE even though they had a few members compared to the nWo's ever-expanding list.
When I said that DX took over the WWE, I am serious. Vince McMahon is still in charge, but Triple H is calling more and more of the shots. Hunter controls NXT and 205 Live and is gaining more control over Raw and Smackdown constantly. Shawn Michaels has moved to Orlando and taken a position as a coach at the WWE Performance Center helping train Adam Cole and other up and coming stars. Road Dogg is now the head writer for Smackdown Live and is often given credit as many fans believe the show produces better content than Raw.
Not only did DX have an impact on the course of wrestling history, they are taking an active role in shaping what Professional Wrestling will be for generations to come.
