Koopzilla, being the giant alter ego of King Koopa in the Super Mario Bros. Super Show!, is based on the world famous Japanese monster, Godzilla. All he is is King Koopa the size of the Crystler Building after eating some of Dr. T Garden's Super Sushi. He and Karate Koopa are the only alter egos from Scayanara. His attacks are only physical and there are no Troopas in this episode. To beat him, Mario, Luigi, the Princess, and Toad caught Koopzilla in a giant steel net, only to be torn apart seconds later. Mario was able to stall Koopzilla by growing as big as him. That gave Dr. Garden the opportunity to create the antidote, Super Sushi Shrinker. To Toad, it was the second largest hypodermic needle he's ever seen (the biggest was his last flu shot). They injected the shrinker into Koopzilla's leg, turning Koopzilla back into King Koopa. He appears in the episode "Mario meets Koopzilla". The episode ends with Mario eating the latest invention of Dr. Garden, Shrinking Sukiyaki.
