3 - 'N Sync vs. Kiss
It's Rock vs Pop in the main event:
'N Sync decided to have some costumes to compete with Kiss:
J.C and Chris had a donkey suit, Lance was a hobo, Justin was a clown and Joey was a pirate.
First Paul Stanley blows up J.C with a laser to make it a clean fight (four on four)
Just a little later, Peter Criss tries to do a superfly on Chris, but slips and splits his skull open on the stairs leading into the arena.
Next, Paul slices up Lance with his laser.
Then Justin tries to attack Ace, but Ace grabs him, climbs the ropes and jumps down into the ring, smearing Justin on the floor, then Ace summons his magic guitar, and uses it to vaporize Justin.
Next Joey is kicked in the groin by Ace, and then kicked out off the ring (he doesn't die though...).
Then Gene tries to burn Chris, but Chris ducks and the fire burns Paul into a pile of ash.
Next Chris ties Gene's tongue into Justin's balloons, and sends him flying away, but Ace slams his guitar into the floor, and a powerful beam is sent up, popping the balloons, so Gene falls down and crushes Chris.
Kiss (Gene & Ace) is the winner!
