Subtitle: Strongest Super-Beast (最強超獣 Saikyō Chōjū)

- Origin: Yapool's dimension
Jumbo King was Yapool's strongest choju and final attempt to kill Ultraman Ace, created by combining the souls of the deceased choju: Unitang, Cowra, Mazaron Man, and Mazarius. Unleashed by Yapool (in the form of The Child of Alien Simon, and in the company of TAC.) Yapool appeared with the dead choju and combined with them to form Jumbo King before them. TAC quickly opened fire, but Jumbo King's hide made him impervious to their assault and during the scuffle, Hokuto was injured by the Choju. With Hokuto out of the picture, Jumbo King vanished.
Later Yapool released Jumbo King again, this time in the heart of a city. With only TAC as it's opposition, Jumbo King easily withstood their assaults and downed them all at once when they tried to ensnare him with a net. With the city leveled from his choju's rampage, Yapool recalled Jumbo King again. The next day Yapool unleashed Jumbo King again, this time in the city where Hokuto was hiding out in. Endangering the lives of several children, Hokuto was quick to evacuate them while TAC tried to destroy the monster with a newly crafted weapon they've created (which failed.) Shortly after killing Alien Simon for revealing his true nature, Hokuto transformed into Ultraman Ace for the final time to battle against Jumbo King. Unfortunately, Jumbo King's size and durability was too much for the ultra to handle and Ace was quickly overpowered. Motivated by the words of all his friends he had made, Ace didn't give up and continued fighting. Ace then fired his Metallium Ray at Jumbo King's head, weakening the choju enough for Ace to use the Ace Slash, decapitating the Choju and killing it. With Jumbo King dead, Yapool's reign of terror on Earth had seemingly come to an end.
- Jumbo King's roar is a reused Draculas roar, which was created from Gorosaurus.
- Jumbo King is the first chimera kaiju to appear in the entire Ultra series.
- When Jumbo King is being created, the image of Giant Yapool appears.
- Jumbo King is the first and (so far) only chimera kaiju that is the final kaiju to be fought after the main villan gets destroyed, most of the chimera kaiju that appear in other shows (like Tyrant or Five king) are fought in the middle of the series.
- Like Salamandora, the fire stream effect ends up coming from the nostril of the costume instead of the mouth.
