It wasn't until Ultraman ZOFFY: Ultra Warriors vs. Jack went on through the 70's with being referred to as 'Returning Ultraman' and etc. Furthermore, when the Original Ultraman and Ultraseven made an appearance halfway through the show, the situation became more complex.

When Tsuburaya created Return of Ultraman, they had originally drafted for the star Ultra Warrior to be the original Ultraman, but when the show aired they left it ambiguous to who the 'Returning Ultraman' really was.

2.6 Ultraman Mebius & the Ultra Brothers.Now unstoppable, Belial takes great pleasure in torturing Zero, beating on him and sucking the life out of Zeros body while gloating about his newfound power. Zero escapes and the two have a rematch, with Belial eventually turning into a monster called Arch Belial. Once finished in this alternate dimension, Belial was going to murder all Zeros friends and then have his Empire destroy everyone in Nebula M78, Zeros home world, while Zero is forced to watch. Zero tracks Belial to this dimension, even taking a human host to survive, but Belial captures him and gloats to Zero about his plans. Renaming himself 'Kaiser Belial' or simply 'Emperor', Belial sends his forces to massacre all opposition. In the movie proper, we find out why Belial was making an army of robots-hes been going from planet to planet in this new dimension, harvesting 'emerald' power sources to power his army and himself. Said clone was a sadistic killing machine, much like his creator. One such clone, Darklops Zero, is the Big Bad of the tie-in movie Ultra Galaxy: Ultraman Zero vs Darklops Zero, making Belial responsible for everything that goes wrong there. After Zero beat Belial, Belial traveled to another dimension, creating Darklops robotic clones of his archenemy Zero and sending them out to cause havoc. Complete Monster: Belial comes back as Kaiser Belial ('Dark Great Emperor'), as bad as ever.Ultimate Zero, the theme that plays for Zero's Super Mode, is perhaps the most epic track of the film, not only showcasing Zero's final triumph over Belial but also Ultraman Noa's grand return to help out the hero in defeating the evil emperor.GlenFire's, Jean-Bot's and Mirror Knight's (heard midway through the track) leitmotifs are all amazing remixes of Fireman, Mirrorman and Jumborg Ace's opening themes, cleverly inserted in the film as they have their moments of glory.
