These were the monsters in the Mutant Mania traveling circus. They include: Medusa, Giant Gila Monster, Scorpio and several other unnamed monsters, such as a horned toad-like creature and a rodent-like monster.
- Dehydration: By simply touching prey, Medusa is capable of absorbing the water from a victim’s body, or even water in general. The more water she absorbs, the larger she grows.
- Melt: Medusa can turn into a liquid state at will or will automatically melt when being introduced to a heat source such as fire.
After being forced to melt, she entered the subway system and then the water reservoir. The electric fence only made her melt yet again and she entered the city water supply and quickly began to grow. Godzilla arrived just in time to fight, but his atomic fire made her melt and cover him, draining him dry also. She escaped and left Godzilla for dead.
She made it out to sea, but Godzilla, revived thanks to H.E.A.T. and the military, was again on an attack. He repeatedly blasted the anemone, preventing her from reshaping or even making an attempt to strike again. When Nick called him back, the Heat-Seeker quickly moved in, sucking up the liquidated Medusa with a huge vacuum meant to clean up oil spills. With heated coils inside, Medusa was trapped inside. What ever happened to her remains unknown.
Giant Gila Monster
Scorpio was yet another of the monsters part of Tobias Wilson's circus. As the name suggests, Scorpio was a gargantuan scorpion who was similar in appearance to Ts-eh-Go and the Mutant Scorpions, making some believe he could an escaped or stolen specimen from the "Third Wave" of mutant scorpions. Scorpio had been trained to do tricks to impress audiences. What happened to Scorpio after the Medusa affair is unknown.
