The Neo Frontier Space World version of Ultraman (ウルトラマン Urutoraman) is an Ultra Warrior who somehow didn't have a relation to the Ancient Giants of Light, instead hailing from an alternate version of Nebula M78 present in the Neo Frontier Space World. After sealing Yanakargie beneath a lake in 1965, he returned in 1996 to help Ultraman Tiga fight the Space Dinosaur when the time-traveling alien Charija sought to use the monster for nefarious purposes.
In the year 1965, the hero Ultraman chased the evil monster Yanakargie to Earth and sealed him away in a lake. Meeting Eiji Tsuburaya, he gave him a stone called the Ultra Star, which could summon him no matter where he was in the universe. Following Charija into the past, Daigo of GUTS was too late to stop the evil monster from being freed by its master. The alien controlled the beast and it started to destroy a town until Daigo transformed into Ultraman Tiga. He started to fight, however, the monster was too powerful for him. Yanakargie grabbed him, and started to siphon Tiga's energy, but before Tiga would die, Tsuburaya used the Ultra Star to conjure a red flying orb which struck the monster. The red orb transformed to reveal it was actually Ultraman. Ultraman restored Ultraman Tiga's energy and both used their signature beams to defeat the beast. Before Ultraman left, he saluted Ultraman Tiga, a salutation that connected both universes. Tsuburaya who watched everything and had told his writer about his first encounter with Ultraman went on to create the series that saved his company from going under and kept it going strong well into Daigo's time.
