Produced by Tsuburaya Productions, Ultraman Neos was initially intended as a TV series but the project was shelved.

In spite of the appearance of similar designs and a cameo by Zoffy, the series is set in an alternate universe.

Having survived the destruction of a space satellite, Genki Kagura was bonded to Ultraman Neos as they fight against the monster brought to life by the Dark Matter mutations with the assistance of HEART and a fellow Ultra veteran, Ultraseven 21.

In the final episodes, Mensch Heit try to exterminate this alien race by sending Grall and threatened the Japanese defense forces for cooperation.

Neos and Seven 21 returned to their home planet as the former separated from Kagura and HEART vowing to restore the Zamu race.
