Ultraman Neos was initially intended as a TV series but the project was shelved. Years later, Tsuburaya turned the concept into a 12-episode direct-to-video series. In spite of the appearance of similar designs and a cameo by Zoffy, the series is set in an alternate universe.
In the first decade of the 21st Century on Earth, the rising of the population results in low quality of life, as well the increasing number of ESP incidents and alien invasions. At Nebula M-78, the information service of the Space Defense Force watches these phenomena and throughout the Space Security Service, a ramification of the group sent a warrior to Earth named Ultraman Neos and his commander Ultra Seven 21. Upon arriving on Earth, Ultraman Neos secretly merges with Genki Kagura to help HEART (Hi-tech Earth Alert Rescue Team) fight monsters both of terrestrial and extra-terrestrial origin.
