* SugarWiki/AwesomeMusic: Kenji Kawai comes back to the franchise after his latest participation in ''Series/UltramanNexus'' to compose an equally amazing soundtrack for the film.
** One of the most notable pieces is [[https://youtu.be/QQUEpYFDvfE Ultraman Zero's theme]] (Electric Guitar version), an action packed yet noble and majestic piece that serves to tell you that amazing action is coming next, it was great enough to become Zero's definite theme.
** [[https://youtu.be/H5Zh8AVyIWA Kaiser Ultraman Belial's theme]] is equally great, being an ominous choir-backed track that serves to establish just how evil and twisted our antagonist is, like Zero's theme it became Belial's definite theme.
** [[https://youtu.be/HVy3aE_HuZg GlenFire's]], [[https://youtu.be/HL62TCp-npo Jean-Bot's]] and [[https://youtu.be/M5LZGHx_zEo Mirror Knight's (heard midway through the track)]] leitmotifs are all amazing remixes of ''Series/{{Fireman}}'', ''Series/{{Mirrorman}}'' and ''Series/JumborgAce'''s opening themes, cleverly inserted in the film as they have their moments of glory.
** [[https://youtu.be/2ND8R6atRjM Ultimate Zero]], the theme that plays for [[spoiler:Zero's SuperMode]], is perhaps the most epic track of the film, not only showcasing Zero's final triumph over Belial but also [[spoiler:Ultraman Noa's]] grand return to help out the hero in defeating the evil emperor.
* CompleteMonster: Belial comes back as [[MultiversalConqueror Kaiser Belial]] ("Dark Great Emperor"), as bad as ever. After Zero beat Belial, Belial traveled to another dimension, creating Darklops robotic clones of his archenemy Zero and sending them out to cause havoc. One such clone, Darklops Zero, is the BigBad of the tie-in movie ''Ultra Galaxy: Ultraman Zero vs Darklops Zero'', making Belial [[GreaterScopeVillain responsible for everything that goes wrong there]]. Said clone was a sadistic killing machine, much like his creator. In the movie proper, we find out why Belial was making an army of robots--he’s been going from planet to planet in this new dimension, harvesting "emerald" power sources to power his army and himself. Renaming himself "Kaiser Belial" or simply "Emperor", Belial sends his forces to massacre all opposition. Zero tracks Belial to this dimension, even taking a human host to survive, but Belial captures him and gloats to Zero about his plans. Once finished in this alternate dimension, Belial was going to murder all Zero’s friends and then have his Empire destroy everyone in Nebula M78, Zero’s home world, while Zero is forced to watch. Zero escapes and the two have a rematch, with Belial eventually turning into a monster called [[OneWingedAngel Arch Belial]]. Now unstoppable, Belial takes great pleasure in [[ColdBloodedTorture torturing Zero]], beating on him and sucking the life out of Zero’s body while gloating about his newfound power.
* EvilIsCool: You gotta admit that Belial's army is very impressive as is Belial himself.
* RetroactiveRecognition: Seven years later, Nao's actor Tatsuomi Hamada would portray Riku Asakura, the human form of the eponymous character of Series/UltramanGeed.
* UnexpectedCharacter: [[spoiler: Ultraman Noa of ''Series/UltramanNexus'' shows up to revive Zero and give him his Shield of Baradhi as the latter's SuperMode in the form of the Ultimate Aegis. Given how prior to this movie the only relation Nexus/Noa had to the M78 Universe was detailed in a backstory magazine to ''Ultraman Nexus'' and the fact that Kenji Kawai, who composed the score of ''Nexus'' was the composer of the film]].
* SugarWiki/VisualEffectsOfAwesome: The entire movie is gorgeous and visually amazing, probably one of the best in Tokusatsu history.
