Cyro Ultraman is the son of Seven Ultraman. As a new generation of Ultraman, Cyro Ultraman is given high hopes. He is good at martial arts and light skills, and has great strength. The early Cyro Ultraman was actually a stunned, impulsive and reckless. He had almost touched the energy core of the plasma spark tower, almost causing a big mistake. Later, Seven Ultraman entrusted him to Leo Ultraman for special training, thus shaping a strong heart and becoming a qualified Otter warrior.

After becoming a qualified Otter warrior, he joined the Otter Cosmic Guard and became a member of it. He fought alongside his predecessors, Ultramans, and has always contributed to the maintenance of world peace. Later, he became acquainted with fellow mirror knights, Red Lotus Flames, Jambert, and Jenning, and together with them created the Ultimate Cyro Guard. He is a bitter enemy of the arch-villain Beria Ultraman and has been fighting him ever since, from the m78 Nebula Land of Light to Earth.
In addition to being active elsewhere in the universe, he also came to Earth. Like any other Ultraman, his time on Earth is limited, set in three minutes. In addition, he also has to find the human body as a host. As long as he finds a host, he will have enough time to complete the task and exert part of his strength. He has guest starred in many episodes on Earth, helping Obu Ultraman, Ged Ultraman, and other new generation Ultraman warriors. This is the Cyro we know in the middle of the day.
The late Cyro is a full-fledged Ultraman warrior. He lost the childishness of the first and middle periods and became mature and stable. He guides the other new generation of Ultraman warriors, fighting alongside them to maintain peace in the universe. These are the stories about Cyro Ultraman.
