Watch Danhausen Debut in WWE After Mystery Box Reveal at Elimination Chamber Following AEW Exit

Former AEW wrestler Danhausen was revealed to be in WWE's mystery box on Saturday at Elimination Chamber in Chicago.

Shortly after CM Punk beat Finn Balor to retain his WWE World Heavyweight Championship, Raw general manager Adam Pearce and SmackDown GM Nick Aldis opened the box at the top of the ramp leading to the ring.

A host of dancers clad in black with red capes then emerged from a coffin, and Danhausen soon joined them.

Danhausen then walked into the ring, and the arena's lights went out. Everyone who emerged from the mystery crate quickly disappeared from sight.
