10 Most Shocking WWE Mystery Revelations

All things considered, DDP probably deserved better than the walk-on role he played in the 2001 Invasion angle. The New Jersey-native was, after all, a three-time world champion during his time with WCW, yet barely got a sniff of the main event after making the jump to WWE.

His introduction, though, was pretty memorable (if a little weird). In June, he was revealed as the mystery man who had been stalking Undertaker's wife, Sara, over the last few weeks. But don't worry: it wasn't creepy or anything - he just wanted to make an impact.

Few fans saw this one coming, mainly because it seemed slightly out-of-character for the man who had spent his last years in WCW pushing for title glory. As a standalone shocking moment, it worked - but the follow-up was disappointing.
