Ultraman Tiga (comrade)
In the year 1965, the Hero Ultraman chased the evil monster Yanakagi to Earth and sealed him away in a lake. Meeting Eiji Tsuburaya, he gave him a stone called the Star of Ultra, which was similar to the Cosmos Stone in that it could summon him no matter where he was in the universe. Following Alien 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. Yanakagi grabbed him, and started to siphon Tiga's energy, but before Tiga would die, Tsuburaya used the Star of Ultra 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.

- This is the first instance of an Ultra Warrior who is an alternate counterpart to an Ultra Warrior from the M78 timeline.
- His surprising appearance in episode 49 was purposely made to celebrate the 30th anniversary of the Ultra Series. However, given the fact that he appeared in Tiga's Universe, he remains a separate character.
- Ultraman's grunts are a high-pitch version of the Showa universe’s Ultraman.
