Ultraman
Guesra was a Brazilian lizard species whose purpose is to scare of pests from interrupting cacao beans. One Guesra egg accidentally carried along into a delivery cacao ship to Japan. As Guesra hatched, it falls into Tokyo sea waters, which at that time was polluted, and mutated it into a giant monster. Guesra was first sighted by several sailors, not knowing it as a threat until the creature grew bigger over time.
Guesra started to attack several shipment supply of cacao beans until the SSSP lured it away from the shipment. However, it instead turned over its attention to a cacao warehouse where Hoshino and his friends were trying to fend themselves from Diamond Kick, a group of jewel smugglers. As the monster is about to attack the SSSP and Hoshino's friends in a police patrol car, Hayata then appeared, and transformed into Ultraman. Guesra attacked first, but Ultraman quickly gained the upper hand, tossing the monster every which way, eventually they both end up in the water. Ultraman then ripped off Guesra's fin. Injured, the monster returned to the ocean, and dying shortly afterwards. The Coast Guard Command
