It was originally going to be produced as a TV series in 1995, but it was shelved in favor of Ultraman Tiga. The project was eventually dusted off and turned into a direct-to-video series in 2000, with 12 episodes produced, in total, earning it the position of the 15th installment in the franchise. Due to the 1995 pilot, both Neos and Seven 21 are considered by Tsuburaya to be earlier Ultramen than not just Ultraman Tiga, but Ultraman Zearth too.
