Ah yes, WCW during the good ol' 1997-1998 era, love it!! Why has it taken almost a year to answer a question!
I admit I had to cheat to find the PPV name (Slamboree 98), but remember the match well, Bowery Death match (i.e. cage with weapons) DDP vs Raven.
Raven had some guys in riot gear to protect him from a mystery attacker (disguised as cameraman, merch stand seller & others) in the weeks leading up to match, then at the end while Raven is handcuffed (I think) to ropes/cage, one of the riot gear dudes smashes Raven with a brutal chair shot, takes off the riot helmet to reveal Mortis, then takes off the Mortis mask to reveal one of the prettiest faces you'll ever see (whobeta!)
Sticking with that PPV, in the introductions to the cruiserweight battle royale, courtesy of the always hilarious Chris Jericho (at his humourous best during those WCW days), how many more matches did he say Silver King had to win to be upgraded to Gold King?
