In order to prepare for Zetton's next strike, Daichi focuses on developing a new armor. He then meets Dr. Touma, who offers to help.

Here to save the day is...
Plot[]
In the middle of battling Zetton, Ultraman X was defeated, even when using Eleking Armor. X tries Gomora Armor but the Oscillation Wave can't penetrate Zetton's Zetton Shutter, even Xio's assistance proven futile. As the monster advances to a weaken X, it instead teleports away. Daichi ends up burns the midnight oil to create a new armor to counteract Zetton, but since he lacks its Spark Doll, the ingredient to create the Cyber Card and Armor is not enough.
The next day, Dr. Kaito Touma, a Spark Doll expert from the UNVER visits Xio and offers them his help as he presents the Zetton Spark Doll, knowing such threat would rise. Interestingly, he was also a friend of Daichi's father and the two were once studying Spark Dolls together. Sayuri and Kamiki excited that Daichi meets a person that knows his father but cautiously doubts on their age. After the completion of Cyber Zetton Card, Zetton wreaks havoc in the city again, prompting X to appear.
The Lab Team sends the Cyber Zetton Card and X uses it but suddenly, the Zetton Armor renders him immobile and worse, the armor can't be removed. Soon, another Kaito Touma appears and attacks the black coated person, revealing him to be Alien Sran Quila. Kaito transforms into another Ultraman and saves a mother-daughter pair from falling rubble. Dr. Guruman identifies the Ultraman as Ultraman Max, and the giant tries to remove X from the armor but instead, the cursed armor controls X and the enslaved Ultraman assist Zetton. Asuna approaches Quila as he revealed that he wanted revenge on Ultraman Max for killing one of his brethren back then. Studying Xio, UNVER and Daichi, he used the man's background and perfectly uses this camouflage. With X's mind completely fells under Zetton Armor's effect, Asuna fought Quila and the alien enlarges to assist Zetton. Daichi uses Cyber Eleking's card and purify Cyber Zetton's corrupted programming, saving Max on time. Now having X back, Ultraman Max finishes off Alien Sran Quila with Max Galaxy and Ultraman X attacks Zetton with the armor, greatly wounding it with Zetton Tornado before freeing himself and defeated it with a mid-air Xanadium Beam.
Approaching Daichi at a sunset, this man reveals himself as Ultraman Max and that he borrowed the appearance of the person he used to fight with. Wanting to help Daichi and X in the future, he lends a portion of his power in a form of a Cyber Card before leaving.
Daichi's Monster Lab[]
Daichi: Daichi's Monster Lab! This time, we're looking at this monster...
X Devizer: Analysing, Zetton!
Daichi: Space Dinosaur Zetton, he was a fierce foe whom had X on the ropes.
X: And the Zetton Armor we get from its Cyber Card contained a nasty trap set by the Alien Sran. But thanks to Daichi's use of the Zetton Armor, we were able to blast through the dangerous foe.
This is the first time that a Cyber Armor was used against the Kaiju the armor was based on.
Sotaro Hayashi and Yuji Kobayashi were the only writers for Ultraman X who had also worked on Ultraman Max. Kobayashi told Hayashi that the current monster armor designs felt too simple and suggested showing the risks involved in using them.[2]
Alien Sran was chosen because it was the first alien in Max, and Kobayashi wanted to revisit and expand its role.
Yuichi Abe says that the goal of this episode was to show how strong Zetton is. To do this, the team used fast-paced action sequences and dynamic visual effects. including the use of GoPro cameras for the action scenes.[4]
Kaito's story ended in episode 39 of Max. His return is shown through Max's human form, the "Young Man Who Protect the Future."
In a 2021 interview, Abe admitted he forgot to change Ultraman Max's Color Timer to red during a battle, but the episode still got positive feedback, and the mistake helped its success.[5]
As one of many selected to celebrate the Ultraman Series' 60th anniversary, this episode was made available on the Ultraman YouTube channel from October 8, 2025 for two weeks, following October's theme of "The Story of Promise."[6][7][8]
