A collection of WWE Superstars and legends including Triple H, Shawn Michaels, The New Day and more have been celebrating the 20th anniversary of group D-Generation X on social media.

An influential and groundbreaking anti-authority group who dominated WWE programming throughout the '90s during the company's lucrative Attitude Era, D-Generation X was founded by Michaels and Triple H who were first joined by initial members Chyna and Hall of Famer Rick Rude.

"@ShawnMichaels & I formed DX w/ a bond built on: Desire, Passion, Drive & we kicked kicked ass! 20 yrs later it's still there & we still KICK ASS!" Triple H, now the COO of WWE wrote on Twitter Thursday alongside photos of himself and Michaels.

"Yea buddy!!!!" added Michaels on Twitter alongside a photo of himself posing with Triple H and fellow DX alumni, Road Dogg, Billy Gunn and X-Pac.

X-Pac, real name Sean Waltman, used the DX anniversary to celebrate Chyna who died in April 2016 at the age of 46. "You were the magic ingredient in the DX Recipe," he tweeted alongside a photo of The Ninth Wonder of the World during her time in the wrestling stable.

Current Smackdown Tag Team Champions The New Day shared a video of their tribute to DX as Xavier Woods played the group's theme song on his signature trombone, Francesca II: Turbo, while Kofi Kingston sang the lyrics and Big E danced.

"So we wanted to pay homage to D-X in the only way that we new how. Happy 20th anniversary!!!" Woods wrote on Twitter alongside the clip.
