The Undertaker made his long awaited return Tuesday night on SmackDown Live ... and just days before Survivor Series, the WWE legend had a stern warning for Team Blue.

Undertaker appeared during a segment of the Cutting Edge and informed Smackdown's team that they'll have consequences to pay if they lose on Sunday -- because he's officially back in action.

“WrestleMania will no longer define who I am … I’m back.”  Adding, "There’s no reason to fear failure, but if you fail, you’ll have reason to fear the Deadman. Team RAW better REST IN PEACE.”

Watch the video below, then sound off in the comments and let us know if you're stoked to see The Dead Man appear on SmackDown Live more in the future.
