"Are you okay, my friend?"
- ―Ultraseven 21 to Neos
Ultraseven 21 was originally a member of the Space Garrison and the Space Security Department. When he was about to be assigned to protect the planet Earth, some emergency prevented him from leaving his post. So, the Security Department requested assistance from the Warrior Command Group.
The protection of the Earth fell into the hands of Ultraman Neos, but once Seven 21 was clear, he traveled to Earth to act as Neos’ backup. The red giant appeared to Neos' host, unleashing the transformation device sealed within him and instructing him to transform to fight the first Dark Matter monster to appear in Japan. The red giant aided the hero several times, but didn’t go into actual battle until Neos was being double teamed by the monsters Sazora and Nozera. The two heroes managed to vanquish both monsters. All the while 21 took on several human forms, often at times taking the image of someone involved with the current situation HEART was investigating.
Ultraseven 21 would continue to aid Neos on and off again until Mensch Heit's assassin, Grall, almost killed Neos. While the red and silver hero managed to vanquish the golden kaiju, he was left wounded. 21 appeared before the dying Neos with Zoffy, giving him much needed energy. On 21's suggestion, Zoffy returned to the Land of Light to gather up the needed life energy to fully heal Neos, warning him not to fight until he returned. Thus, when Mensch Heit arrived on Earth, it was up to Ultraseven 21 to thwart his attacks.
However, Mensch Heit's powerful and bizarre attacks easily overpowered 21. Even when Neos was summoned to his side, both were almost killed at the feet of the warlord. However, an unexpected ally would soon help: the last of the people of Zamu. The last member of the race sacrificed himself to recharge both Ultraman Neos and Ultraseven 21. With renewed strength, the pair threw several different energy attacks at the fiend. At long last, Mensch Heit was killed and the Earth saved. Ultraman Neos separated from his host. Their missions completed, Ultraman Neos and Ultraseven 21 returned to Nebula M78 to await further orders.

He had taken on several human forms during the course of the series but the manner in which he transforms back is almost always the same in some regard. 21's eyes glow followed by a transformation.
