From the August 23rd, 1999 episode of WCW Monday Nitro, KISS
performs lip-syncs (I suppose they’re cartoony an theatrical enough that somebody thought they’d fit in on a wrestling show) and reveals
The Kiss Demon!
AKA The Demon
AKA Brian Adams (AKA: Demolition Crush, AKA: Kona Crush) in KISS makeup.
The role was soon taken over by Dale Torborg.
I’m just going to quote from Dale’s Wikipedia page which explains nicely what a complete disaster this entire idea was and how it backfired on WCW big time:
In 1998, he started to get a push as the MVP but after two matches as the MVP, he was asked to do a KISS character named The Demon. WCW head Eric Bischoff struck a deal with the rock band KISS to create a KISS themed wrestler, “The Demon”, a gimmick that was meant to be the wrestling alter ego of performer Gene Simmons. Torborg originally was told he was the Demon and was abruptly taken out due to Brian Adams having much more experience in the ring. Adams admitted to never feeling comfortable as the character. The gimmick was played twice by Brian Adams, rejected by him without wrestling a single match, and given to Torborg. He was managed by Asya (Christi Wolf), whom he later married. The “Demon” character was originally supposed to be the beginning of a stable called The Warriors of KISS, in which the other original members of the band would have a wrestler representing their look and gimmick. KISS was guaranteed their “Demon” themed wrestler would wrestle a Main Event match with the contract they made with WCW. This was supposed to happen at a special 1999 New Year’s Eve PPV against Vampiro. The PPV and the match were taken off the table, however, after Eric Bischoff lost his position in September 1999. In order to fulfill the contractual obligation, he was booked in a “Special Main Event” match at Superbrawl in early 2000.
Uncharacteristic to “Main Event” matches, it was the fourth match on the card and saw Torborg face The Wall which saw The Wall win with a chokeslam. Because Bischoff lost his position before the character’s wrestling debut, The Demon character got off to a rocky start, losing to Terry Funk in its debut. Bookers at the time wanted to make Eric Bischoff look bad. Torborg contends that the character was hurt because the KISS concert to debut The Demon was one of the lowest rated segments in the history of WCW Nitro up to that point and even though Bischoff believed in the character, others believed it was dead on arrival.
Afterwards, he was known simply as “The Demon” and placed in a stable with Vampiro and The Insane Clown Posse called The Dark Carnival. He later turned against the group and feuded with Vampiro.
So WCW gave KISS a ton of money for something that ended up turning them no profit, and cost them ratings and viewers in the long run.
Yup, that sounds like typical WCW to me!
