Ultraman Sizer

Ultraman Sizer was an orphan picked up by Ultraman Zero on the battlefield. His parents were all killed in the battle. Therefore, he was brought back to the Kingdom of Light by Ultraman Zero. After seeing him, Ultraman Seven decided to adopt him as his second son and raise him with other Ultraman. At first, he was a little arrogant and thought that he was strong just because he defeated a monster. Therefore, Ultraman Seven scolded him a lot. In order to change his problem, Ultraman Seven handed him over to his own son Ultraman Zero and asked Ultraman Zero to train him so that he could become a qualified warrior as soon as possible. But only halfway through the special training, an unknown life form appeared on the earth. The unknown life form was code-named MK24. It was a plankton similar to Sphia. Therefore, Ultraman Sai Ze bid farewell to his father and brother, as well as other uncles and seniors, and came to the earth to merge with a young man named Jersey. Thanks to their efforts together, he became a real Ultra warrior. In the end, Jersey left the earth with him, returned to the Kingdom of Light to hand over the mission, and became the messenger of light in the new century.
