Ultras
The Giants of Light
Ultraman Decker
Ultraman Decker
Ultra Dimension! Ultraman Decker: Flash Type!
The Giant of Light that protagonist Kanata Asumi transforms into. His basic form is called the Flash Type, and he can Type Change into the physically powerful Strong Type and the supernaturally powerful Miracle Type.
- Back to Base Form: The finale has him start out in his Dynamic Type, but for the final hit he uses his Flash Type and achieves a Glitter Form through it.
- Bash Brothers: With Terraphaser after it is fully activated, after the events of episode 11 and episode 12 they become a kaiju-fighting team that cooperates against their foes in harmony. It lasts until episode 14 where Terraphaser is hijacked by Agams and becomes an enemy.
- Brought to You by the Letter "S": Decker's ears are shaped like the letter D
, one of the features that separates his head design from Dyna's. - But Now I Must Go: After Mother Spheresaurus' defeat, Decker leaves the present timeline and goes back to the alternate future with his original host, Decker Asumi, with Kanata bidding him farewell.
- Composite Character:
- His ability to summon ally kaiju to fight enemies is a trait taken from Ultraseven. Another trait taken is that his injuries in human and Ultra form aren't healed when Kanata transforms or de-transforms and carry over if they're not given time to heal.
- His Miracle Type's ability to calm down and subdue monsters peacefully brings to mind Ultraman Cosmos' Luna Mode.
- Him partnering up with a benevolent version of a usually malevolent Ultra Series mecha made by the series' defense team is a trait taken from Ultraman Z. Unlike Z, however, their partnership doesn't lasts long after Agams hijacks the robot, at least until the finale where it falls back into GUTS Select's hands for good.
- Like Ultraman Tiga he gains a Golden Super Mode in the finale after a Disney Death and once his purpose is done his power leaves his host behind now that the world is at peace.
- Contrasting Sequel Protagonist: Compared to Ultraman Dyna, who mostly used Miracle Type; Decker has used Strong Type a lot more than his other form. Also contrasting Trigger's higher usage of Sky Type over Power Type compared to Tiga's reversed preference of transformation.
- Cool Sword:
- After Sphere Megalothor is defeated, Trigger passes on the Ultra Dual Sword to Decker to defend Earth since that is the purpose why the sword was given to the former. Decker uses it in Decker Mode and by scanning Ultra Dimension Cards is capable of using a variety of attacks.
- When in Decker Dynamic Type, the Decker Shield Calibur becomes a Double Weapon in Calibur Mode.
- Dual Wielding: When in Dynamic Type he can do this with the Ultra Dual Sword and Decker Shield Calibur, especially offensive if the latter is in Calibur Mode.
- Fashionable Asymmetry: A common feature to all of Decker's basic three forms is that he has his Color Timer on his left pec, as well as armour on his left arm. The "fashionable" part is even acknowledged in-universe by Hotta and Marluru in the first Special Episode. It is done away in his Super Mode Dynamic Type.
- Finishing Move: Unlike Trigger, whose finishing moves are named the same as Tiga's, Decker's finishing moves are named similar, but slightly different than Dyna's:
- Flash Type: Selgend Beam: After charging up energy with his arms, an Ultra beam is fired when putting his arms in a "+" position.
- Strong Type: Dolnade Braker: Flames engulf Decker's right fist to enhance his Megaton Punch.
- Miracle Type: Realiut Wave: An orb of condensed space created by a black hole is thrown by Decker onto the opponent.
- Dynamic Type: Dymude Beam: Similar to Selgend Beam.
- Foreshadowing: Dynamic Type's name and the use of the Decker Shield Calibur are foreshadowed in the second verse of the opening "Wake Up, Decker!", which uses the words "dynamic" and "sword & shield" in Gratuitous English during the same part where the first verse references Decker's base forms.
- Golden Super Mode: Gains a Glitter form in the finale as his final transformation and move against Mother Spheresaurus.
- Knightly Sword and Shield: When as Dynamic Type he is Dual Wielding his Ultra Dual Sword and Decker Shield Calibur in Shield Mode.
- Meaningful Name: He's an ultra who carries Ultra Dimension Cards and using them to summon allies for help, hence the name Decker.
- Decker also serves as a pun on the Latin deca, marking Decker as the tenth New Generation Ultraman to appear in a separate show (since R/B and Taiga have separate Ultramen as New Generation).
- In episode 3, Kanata awkwardly claims that he named him Decker because the Ultra's big (デカい, dekai) and cool (かっこいい, kakkoii) when Ichika questions how he knew Decker's name.
- Come episode 15, it is revealed that Decker's name comes from his original host, Decker Asumi.
- Multiform Balance: Like Ultraman Dyna, Decker has 3 main forms and a Super Mode separate from Dyna:
- Flash Type: The most versatile and least specialized form of Decker, it can be used against various opponents and adapt to various situations according to Decker's needs.
- Strong Type: With more raw power but less speed than Flash Type, this form specializes in close-quarters combat and using brute force to overpower the opposition.
- Miracle Type: Far less oriented towards physical combat, this form specializes in ranged attacks and various powerful mystical techniques. Among its powers he shows the ability to reverse aging on living beings, catching thunder and redirecting it and even creating a giant Color Timer-shaped portal in the sky.
- Dynamic Type: Decker's most powerful form that comes with a Mix-and-Match Weapon called the Decker Shield Calibur that has a Shield Mode and a Calibur Mode.
- Mysterious Past: Who Decker is and where he came from is a huge mystery with Kengo noting that he most likely is not an Ultra from the ultra ancient past like Trigger. The Mysterious Man's presence in episode 14 further complicates and raises questions about his existence since he can transform into Decker with Kanata's device but acts unlike Kanata's own transformed state. It is finally revealed in episode 15 that the man is Decker Asumi, the human form and the original owner of the D Flasher who is from an alternate future and a descendant of Kanata Asumi of that timeline.
- Non-Standard Character Design: The first heroic Ultraman since Ultraman Nice to have a Color Timer not on his chest, but rather on one of his pecs.
- Self-Duplication: In Miracle Type he can make copies of himself to do a Doppelgänger Attack.
- Star-Spangled Spandex: Decker's forehead and chest armour appears to depict a swirling galaxy.
- The Worf Effect:
- Is decisively beaten by Sphere-Neomegas in episode 12, to demonstrate how powerful the Sphere-assimilated bioweapon is and drive GUTS Select to deploy Terraphaser to defeat the seemingly unstoppable foe.
- In episode 14 he's overwhelmed by the resurrected Spheresaurus and later defeated by the hijacked Terraphaser. Then it gets turned on its head when Decker Asumi arrives and transforms into Decker himself, allowing the Ultraman to have a fighting chance and nearly win against both massively powerful opponents, even as his Timer blinks red.
- Worf Had the Flu: He winds up brutally beaten and nearly killed by Deathdrago in the second episode in a crushing Curb-Stomp Battle, however this is because Kanata had sustained a leg injury in human form and thus couldn't fight properly, once Miclas roughs up Deathdrago a bit to make things even, Decker is better able to fight and eventually win.
Ultraman Trigger
Ultraman Trigger
The Giant of Light who once saved Earth less than a decade in the past. With Decker protecting Earth, Trigger takes up the job of the Mars Colony's defender after he is trapped with the inhabitants of the other planet by the Spheres, but with help from Akito arrives on Earth to combat the threat of the returning MegalothorSee his section here.
- Cool Sword: While the Circle Arms is still accessible, Trigger is now armed with the Ultra Dual Sword he gained from the future Yuzare before passing it on to Decker.
- Energy Absorption: He does this to Mother Spheresaurus to absorb the Eternity Core energy she took and using it empower Kanata's transformation into Decker.
- Hero of Another Story: While Decker is busy defending the enclosed Earth, Trigger is fighting on Mars against the more active Spheres.
- My Greatest Second Chance: He still regrets his inability to save Carmeara even though it already has been a decade after her death. Carmeara being revived inside Sphere-Megalothor gives him a second chance to save her.
- Nice Job Breaking It, Hero: Kengo's battles against the Spheres allowed them to learn about the Eternity Core.
- Superman Stays Out of Gotham: His absence is explained due to being off Earth before the Spheres sealed the planet along with Mars needing him as their defender due to also being attacked by Spheres.
- The Worf Effect: To showcase the sheer power of Mother Spheresaurus, Trigger was knocked out of Glitter and send falling into orbit after a Curb-Stomp Battle in space.
Ultraman Dyna (Unmarked Spoilers)
Ultraman Dyna
Another legendary Ultraman from the Neo Frontier Universe. According to Decker Asumi, he acts as humanity's ally in the alternate future against the Sphere threat.See his section here
- The Cameo: Appears briefly in episode 15, Decker omits his name but he is referred to as the additional Ultraman that helps out the alternate future's humanity against the Sphere threat. He appears fully in the show's present era in episode 21 to help and pass on Tiga's Multi Type and his own Flash Type Ultra Dimension Cards to Kanata Asumi/Ultraman Decker.
- Mythology Gag:
- Uses his Power Type against Sphere-Geomos, as he originally did against Neo Geomos in his home series.
- He encourages Kanata before leaving by saying that no one knows what will happen in the future, the same words of encouragement he once said to Alien Lasesta in his home series.
- The Voiceless: Much like Decker in the first few episodes, he isn't heard vocalising outside of the usual battle grunts, but Kanata can hear his words of encouragement as he leaves at the end of the episode.
Giants of Darkness
Carmeara
Carmeara
An ancient giant who had died nearly a decade ago but is revived within Sphere-Megalothor and freed by the powers of Decker Miracle and Yuzare.See her tropes here.
The Anti-Sphere Unit GUTS-Select
The expert team formed within the TPU, newly reformed with new members after the end of Ultraman Trigger as anti-Sphere Unit.Members
Kanata Asumi
Kanata Asumi
Portrayed by: Hiroki Matsumoto
He is cheerful and a little goofy, but he is a kind-hearted young man who cares for others. He never ignores someone in need, and sometimes goes overboard throwing heart and soul into whatever task is before him.
After the Sphere attack, his peaceful life is taken away and he is gifted Decker’s “light” when he stands before an enemy, ignoring all danger.
Although uncertain what it means to become an Ultraman, he takes to it optimistically and tries to use his new-found power for others. To this end, he joins the newly-reformed expert team GUTS-Select, and with his fellow young team members they stand up against the threat of the Sphere.
- Badass Normal: Even before merging with Decker, Kanata tried his hand at rescuing a woman trapped underneath rubble and even fighting off a Sphere with a rifle gun, though the latter almost resulted in his death had it not been for Decker's intervention. He becomes even more badass following a year of training under TPU.
- Body Horror: Like Agams he gains a Sphere infection during his direct contact with them, except his case is much more horrifying as it extends to his arm from his abdomen and causes him even more pain than Agams had. He is able to free himself of it and any horrifying fate that might have followed in the finale when his will to fight and make a better future overcomes the Sphere's influence.
- Character Development: He starts out without much of an idea on his future, instead merely doing things in the heat of the moment to save lives, but gains a stronger resolve after some pep words from Professor Asakage and much later on from Decker Asumi, his descendant, when his conscience is plagued by Agams' betrayal.
- Contrasting Sequel Protagonist: While both Kanata and Kengo are Nice Guys, they differ in many aspects:
- Kengo lived with his mother in the Martian colony since he was born and found in the site of Ultraman Trigger's statue being the giant's reincarnated light, Kanata lived on Earth since he was born and alongside his whole family.
- Kengo was a botanist who joins GUTS Select after Chairman Shizuma realizes he's inherited Trigger's light, Kanata was a rice cracker worker who joins GUTS Select after impressing Captain Taiji with his bravery and determination then going through a year-long training regime in TPU.
- Kengo got along with pretty much everyone in GUTS Select and Akito's disdain for him never was reciprocated, Kanata and Ryumon don't get along and their clash in ideologies reaches a mutual dislike at some points, also rather than turn into friends by the end of the second episode, Kanata and Ryumon more or less just learn to work together, however reluctantly.
- After obtaining their respective Super Modes, Kengo became more determined to fullfil his duties as an Ultraman till the point of self-destructive behavior due to taking too much burden by himself, Kanata continues to have doubts onto himself and humanity due to Agam's words, which even made him unable to transform against Sphere-Geomos due to humanity's hands in the monster's existance.
- This also goes for their Fusion Dance. Kengo fused with Trigger because he is Trigger's reincarnation, while Kanata fused with Decker Asumi, a descendant of his.
- Composite Character: Much like Decker (Miracle Type) being Ultraman Dyna (Miracle Type) with Ultraman Cosmos (Luna Mode) abilities, Kanata is Shin Asuka but with Haruno Musashi's tenderness as he lacks Asuka's cocky and hot blood antics. He is also shown to be reckless and childish at times, much like Asuka and Musashi were when they were still rookies.
- Disney Death: He gets almost eaten by a Sphere before his merge with Decker allows him to escape and survive.
- Earn Your Happy Ending: After all the crap he goes through in the series and nearly losing his faith on his cause more than once, the finale has him defeat Mother Spheresaurus for good and once and for all undo the Sphere barrier and their invasion. He is able to ultimately reunite with his family once Mars is freed by his actions as well.
- Innocently Insensitive: He mistakes Alien Metron Nigel for Marluru after undergoing a growth spurt, indicating he thinks all Alien Metrons look the same.
- Nice Guy: He's a simple grain food worker who nonetheless is kind to people, offers free cookie samples to Ichika upon meeting her, tries to save a trapped woman from rubble and is willing to give his life for the greater good. All these traits impress Captain Taiji enough to consider recruiting him into GUTS Select.
- Save the Villain: Due to both having grown to care about Agams as Yuichiro Asakage, and Decker telling him to save him Kanata spends a good chunk of the series trying Agams and convince him to turn back to good. He succeeds near the finale, albeit shortly before Agams is killed by Mother Spheresaurus.
- Sensitive Guy and Manly Man: Is the more Sensitive Guy to Ryumon's Manly Man.
- Shut Up, Hannibal!: Tells the Mother Spheresaurus that if free will does inevitably lead to a future of sadness, then humanity will surpass that future.
- Was It All a Lie?: After Agams reveals his true nature and that all his good deeds as "Asakage" had ulterior motives, Kanata asks the alien if he ever intended to protect Earth as he had promised to his face. He is understandably upset when the alien laughs off his concerns and silently reiterates his point by calling him naïve.
Ichika Kirino
Ichika Kirino
Portrayed by: Yuka Murayama
Bright and optimistic, she is hot-blooded with a strong sense of duty and responsibility. She is athletic and though small in stature she can dodge and maneuver quickly.
She hopes to bring back peace to Earth so that people can continue to follow their dreams without being intruded, and save her friends who are lost in the attack of Sphere.
She tends to overthink things leading the captain to call her a “headstrong genius.”
- Ace Pilot: Pilots the GUTS Falcon in the finale against Mother Spheresaurus, at first supporting the plan to restore Decker's light, then directly fighting the leader of the Sphere alongside hre teammates.
- Action Girl: Like past female members of attack teams, Kirino is no slouch in combat and does not hesitate to fight in the open against Kaiju and aliens.
- A Day in the Limelight:
- Episode 5 has her on the spotlight as her friendship with Yuko and wish to save her Eleking from being put down by force take the bulk of the plot.
- Episode 20 focuses on her and Sawa's investigation into the Ragon situation, as well as their bonding with Urasawa and coming to know of her past and motivations.
- The Heart: Works as this in the trio of Kanata, Ryumon and herself; while Kanata is kind-hearted he is at odds with Ryumon in a mutual bickering sense while Kirino acts as the mediator between them, doing her best to help them get along when they get too pushy with each other.
- Screw the Rules, I'm Doing What's Right!: Her mindset is not to do the things she's just ordered to or that seem safe and plausible to do, but rather to do things that will lead to good, even if they are dangerous. This is what causes her and Kanata to become friends quickly, as she witnessed firsthand that Kanata has a similar mindset. Deconstructed in Episode 5, as not only does her plan to steal the city-powering battery to feed Elly nearly cost her Captain Murahoshi's trust, she also wrongly assumed TPU was going to prioritize killing Elly for being an alien kaiju, when the truth is they would also provide aid to extraterrestrial species.
- What the Hell, Hero?: Played With. When Kanata reveals his identity as Decker in the finale to all of GUTS-Select, Kirino is upset but less about her feelings on the matter, but more on how she felt Kanata had been fighting alone as Decker all this time, leaving himself burdened with the responsibilities.
Soma Ryumon
Soma Ryumon
Portrayed by: Daichi Nobunaga
Always calm and collected, his cool personality doesn’t often let him show his emotions.
After being saved by a TPU member as a boy when he was caught in a monster attack, he began training himself and found his calling in GUTS-Select, joining against his father’s wishes. He swore to become the best to prove to his father that he made the right choice.
He always assesses the situation with a critical eye, leading the captain to call him an “observant genius.”
- Ace Pilot: Pilots the GUTS Hawk in the finale against Mother Spheresaurus, at first supporting the plan to restore Decker's, then directly fighting the leader of the Sphere alongside his teammates.
- …And That Little Girl Was Me: After learning that the crux of the investigation into Captain Murahoshi is that he abandoned his mission to save a little boy, Ryumon cross checks the date of the incident and clears things up when he realizes that he was the boy Murahoshi had saved.
- Anger Born of Worry: He accosts Kanata after Decker kills the Spheresaurus, angrily telling him that it wasn't his place as a civilian to fight. It's clear by his tone and his shocked reaction when Kanata was seemingly killed by a Sphere that his anger was born of terror that a civilian had died in front of him while he was helpless to prevent it.
- Contrasting Sequel Protagonist: To Akito Hijiri, who like him is the main protagonist's sort-of-rival.
- Akito was born to a humble family and wound up adopted into the wealthy Shizuma family after both of his parents died fighting Deathdrago while helping Chairman Shizuma. Ryumon was born to a wealthy family and rather than losing his parents during a kaiju attack, he was merely separated from them and was rescued by a TPU member, causing him to develop a need to become a member to protect lives.
- Akito had a one-side dislike of Kengo, and warmed up quickly to him once they had a bit of a heart-to-heart in the second episode. Ryumon and Kanata's enmity is more mutual and it takes until the sixth episode for them to leave most of their animosity behind.
- Akito focused on the scientific and technological aspects of GUTS Select as their prodigy chief scientist who took his job as an open-field agent as more of a secondary and complimentary task. Ryumon is an open-field soldier who prioritizes saving civilians and mostly focuses on tactics and logistics.
- Both of them have high expectations put upon themselves by their own admission relating to their desire to save lives after a traumatic incident in their childhoods, but while Akito's were related to his wish to become Ultraman, Ryumon's are directed towards being a competent GUTS Select member.
- Akito knew from the start that Kengo was Trigger and resented his inexperience for it. Ryumon starts out unaware of Kanata's identity as Decker and his resentment is geared towards him seeing Kanata as a rookie who could compromise his entrance and later membership in GUTS Select and only finds out near the finale the truth, at which that point he keeps quiet on his knowledge until the finale when he comes clean to Kanata about it.
- Death Glare: He and Kanata gave a couple of these to each other in the second episode.
- Following in Their Rescuer's Footsteps: Joined the TPU because he was once saved by a member when he was a kid. Later on it turns out that member was Captain Murahoshi.
- Jerk with a Heart of Gold: Episode 6 reveals he has high expectations towards himself and his teammates because he takes rescuing civilians very seriously as a result of being saved by a TPU member when he was a kid. He also acknowledges the fact that Kanata's been training as well, showing that he recognises his teammates' hard work despite his high standards.
- Non-Idle Rich: Was a rich kid when he was a child. He got inspired to join the TPU to save people when a member saved him back then and now he is a member of GUTS-Select.
- Not So Above It All: Just like Kanata, he also gets excited over Terraphaser and even gushes over thinking about how the one-hit-kill from the TP Mega Buster is terrific.
- Secret Secret-Keeper: He discovers that Kanata is Decker in #22, but keeps it to himself and in the subsequent episodes gives Kanata an opening to transform. He only reveals his discovery in episode 24 once Kanata recovers from his battle with Terraphaser.
- Sensitive Guy and Manly Man: Is the manly man to Kanata's Sensitive Guy.
- Teeth-Clenched Teamwork: He barely tolerates Kanata, who himself doesn't tolerate him much either, and even after spending time as partners in episode 2 the two still don't get along all too well. They do reach an understanding after discussing their motives for joining GUTS-Select in episode 6, and some of the tension between them is resolved.
Yuichiro Asakage (Unmarked Spoilers)
Professor Yuichiro Asakage/Agams the Bazdor
Portrayed by: Yu Koyanagi
Click here to see spoilers
A scientist working for the technology division of TPU and the developer of the gear GUTS-Select uses. His expertise in machines make him a valuable member of the organization...
Agams the BazdorHowever, that's not what he actually is; his true identity is that of the alien Agams from Planet Bazdo, who manipulated events to build a weapon to destroy Decker with and help the Sphere conquer Earth.
- A Day in the Limelight: Before he becomes an antagonist that is. He is partially the focus of #11 due to being the one to convince the higher-ups to restart DG001 project to create Terraphaser and explaining the robot's capabilities towards the main trio.
- Aliens Are Bastards: His true identity is Agams, an alien of Planet Bazdo, who plans to use Terraphaser to defeat Decker and let the Sphere conquer Earth. Though his evil is only a result of the trauma he's experienced from the Spheres' attack on his homeworld. He eventually abandons this when reminded of his dead wife.
- Astonishingly Appropriate Appearance: His bodysuit used to pilot Terraphaser is colored the exact same way as the robot. As is his "Phase Riser".
- Awesome Mc Cool Name: Even though his name from translation is normally Alien Bazdor Agams by Ultra Series standards, due to him from Planet Bazdo. His name being written as Agams the Bazdor is already awesome in its own right.
- Big Bad Duumvirate: He is revealed to have been secretly preparing to assist the Sphere invasion and come episode 14 drops all of his previous pretenses of good to begin helping the invaders out directly.
- Body Horror: In episode 22 he reveals he let the Spheres take over his body, with the reveal punctuated by the Spheres' body tissue bursting out of his right cheek. They are only undone when he finally redeems himself and fights off their influence.
- Dark Is Evil: His bodysuit used as Terraphaser's pilot is a pitch black complimented by blue streaks like his robot's own scheme and he is quite nasty once he shows his true intentions. There's also his pseudonym's surname Asakage, which translates to "morning shadow".
- Evil All Along: He turns out to both be an evil alien and to have been developing Terraphaser so as to defeat Decker and help the Sphere take over Earth and consume it. He reveals his true colors in episode 14.
- Evil Counterpart: The Phase Riser is one to the GUTS Sparklence, being a blaster-like weapon that can utilise the powers of kaiju and allows Agams to summon and control Terraphaser by flipping its barrel, and even has the same voice actor for its announcements.
- Evil Sounds Deep: Not the man himself, but his Phase Riser has a significantly deeper voice than the Ultra D Flasher, which emphasises its role as a device he uses to control Terraphaser to defeat Ultraman.
- Expy: Of Kei Fukuide, as an evil Human Alien who poses as a respected and kindhearted intellectual on Earth but reveals his true intentions as a servant of evil out to destroy the series' Ultraman. For added bonus, Agams is named after a fictional character from Kei Fukuide's Cosmo Chronicle novel, and his Sanity Slippage in Episode 22 also has parallels to Kei's own breakdown while overloaded on the Ultra Capsules' energy in Episode 12 of Geed. Unlike Kei, Agams eventually redeems himself at the cost of his life.
- Foreshadowing:
- His closing words in episode 11 help to lead up to his reveal as an evil alien.
- When Kanata asks him in episode 14 about his research and pride of Terraphaser he states that all the research is for "his home planet", which sounds off when it seemed he was a human of Earth, and makes more sense when it's revealed that he's neither human not from Earth.
- His Madness Mantra only began in the same episode he revealed himself as a villain, and after his defeat in episode 15 he hallucinates the image of a woman speaking to him. Said mantra would be revealed to be words he repeats to preserve his memories as best as he can from the Sphere influencing him and that they were among her last words before her death.
- Freudian Excuse: His homeworld was invaded by the Spheres as an indirect result of humanity advancing into space, leading to his wife's death. This led to him marking mankind as his enemies and opting to exterminate them in the far past to avoid them ever reaching the confines of space.
- Gadgeteer Genius: He is one of people developing the gear GUTS-Select uses, including the GUTS Hawk, which he designed with the ability to combine with the GUTS Falcon for even more firepower.
- Go Out with a Smile: Dies with a positive face and a hopeful attitude, as despite his end being inevitable, he has faith that Kanata can save everyone.
- Human Aliens: Doesn't look any different to a normal human despite being an alien, letting him blend in without issue to prepare his plans.
- Heel–Face Turn: After being reminded by Kanata one last time of his wife's wishes and being pointed out that he really just wants to die but would be a bad thing for everyone, Agams finally turns good and helps Decker destroy the Sphere Barrier then against Mother Spheresaurus when she arrives.
- Hypocrite Has a Point: Agams was right to call out on mankind in front of Kanata for utilizing the Spheres as an energy source despite having little to no knowledge of the creatures, leading to the Sphere Geomos' creation. Later on, he is forced to drag Terraphaser away in the middle of the fight when his robot exhibits the Spheres' energy reading, showing that he is also guilty of his earlier rhetoric.
- Knight of Cerebus: The series is already dark from the very beginning while keeping up lighthearted moments. Asakage revealing his true colors, hijacking Terraphaser and making short work of Ultraman Decker shows that things are going down south for the heroes.
- Laser-Guided Amnesia: At the end of episode 22 he ends up losing all his memories of the present day and seems to only remember events prior to the Sphere invasion of his planet.
- Love Makes You Evil: The tragic loss of his wife is his motivation to destroy Earth in the first place.
- Madness Mantra: Before he reveals his true nature as an evil alien, he utters some words which appear to have no coherent meaning with each other. Episode 15 would reveal that these words were once said by Laelia, a woman he cared about but is implied to have been killed in the Sphere invasion of his homeworld which led to his descent into villainy. As he's taken over by the Spheres in episode 22, he starts forgetting the mantra and can't go any further than "flowers", which drives him to a Villainous Breakdown since the episode reveals that said woman was his wife.
Asakage: "Flowers… Trees… Sky… Wind… Clouds… Sun…"
- The Man Behind the Monsters: He's the one who brought the Sphere threat to the present timeline Earth, in hopes of destroying the planet and its civilizations earlier in history so it won't ever advance into space and according to him, doom his own home planet in the process.
- Mirror Character: Episode 15 establishes him as this to Ignis, while at the same time acting as his Evil Counterpart. Both are Human Aliens who lost their home planet to an alien invasion, or in Ignis's case, by a certain genocidal Dark Giant and even witnessed their loved ones dying in front of them which heavily traumatized them. Ignis would embark on a vendetta quest against Hudram while finding a means to defeat him, by becoming Trigger Dark later on, and remains as the Dark Giant's host to help Kengo and GUTS-Select in their final bout against Megalothor. Agams' home planet of Bazdo were overwhelmed by the Spheres despite that his people are still fighting back against them, he develops great resentment towards Earth, humanity, and the light of Decker for bringing the Spheres to them. Agams wanted nothing but to let the Spheres devour the Earth and will stop at nothing to remove Ultraman Decker out of the equation to achieve that end goal. Finally, both redeem themselves once they are convinced well enough and even help stop the main threat, but while Ignis lives after temporarily giving his power to Kengo to transform into Trigger's true final form: Trigger Truth; Agams is killed by Mother Spheresaurus, bidding farewell to Kanata and hoping he can make things right.
- Non-Action Guy: Since he is a part of the technology division, he only visit GUTS-Select to explain how to use the new technology he developed. It turns out to be part of his cover, once he reveals his true intentions, he takes to the battlefield by controlling Terraphaser directly with his own nervous system.
- Nothing Personal: He tells a downed Kanata that he has nothing against him but the light (Decker) inside of Kanata and is just about to shoot him had he not been interrupted.
- Secret Secret-Keeper: He discovers Kanata's secret identity at the end of Episode 12 when he accesses Hanejiro's combat data.
- Redemption Equals Death: Redeems himself in episode 24 after Kanata gets through to him by reminding him of what Laelia wanted. He ultimately sacrifices himself to shield Decker from Mother Spheresaurus' attack, perishing in the process.
- The Resenter: Greatly resents Earth and all of humanity due to their expansion being partly responsible for the Spheres taking over his planet and getting his wife killed as he himself believes.
- Set Right What Once Went Wrong: His goal from his point of view is this, by destroying Earth assisting the Sphere he intends to have his planet never be taken by the Sphere to begin with and simulataneously saves the life of his wife by preventing the Sphere attack that caused her death.
- Set Wrong What Was Once Made Right: However, others' perspectives, such as Decker Asumi's, prove that his plan would ultimately result in this by causing unnecessary death and devastation that would doom not just Earth but other planets instead of saving any.
- A Sinister Clue: He holds his Phase Riser in his left hand, suggesting he's left-handed.
- They Died Because of You: A racial example, as Agams blames the entirety of mankind for Planet Bazdo's fall into the Sphere's clutches. Kanata falls into Heroic BSoD whenever he is reminded of this. It gets played more directly when it's revealed that his wife, Laelia, died in a Sphere attack which caused him to develop a fully personal hatred of mankind.
- Time-Traveling Jerkass: Is an alien who came from a different time period to the present and is evil to boot, bent on killing Decker and his host and then letting the Sphere take over and devour Earth.
- Together in Death: His final vision of his wife shows that his death finally reunited him with his loved ones. The final episode confirms it as Kanata sees a vision of Agams and Laelia together after defeating the Mother Sphere who silently bid him goodbye before disappearing.
- Tragic Villain: As his personality while he lost his memories in episode 23 shows, he was once an idealist who believed he could protect both his home and his friends from other planets against the Spheres' threat. The Spheres conquering Planet Bazdor and killing his wife made him fall into despair and hold a grudge against humanity, leading to him renouncing his previous idealism and collaborate with the Spheres to destroy Earth.
- Transformation Trinket: To pilot Terraphaser he employs one of these, the "Phase Riser" which teleports him to the inside of the mecha and lets him control it with his own nervous system.
- Villainous Breakdown:
- After Decker Dynamic overwhelms Terraphaser and destroys Spheresaurus again, he loses it and starts screaming before Decker destroys Terraphaser and leaves him severely injured.
- He gets another one in episode 22 after the Spheres assimilate him and start erasing his memories of Laelia. He spends his entire fight with Kanata screaming and snarling at him, stating that he doesn't care if he loses himself as long as he can take revenge on Earth.
- Villain Override: In episode 14 he hijacks Terraphaser's control from Hanejiro and takes over the machine for his own uses for the rest of the series.
- Walking Spoiler: Becomes this after the events of episode 14, as revelations of the episode change the entire course of the series and puts his character in an entirely new light.
- What the Hell, Hero?: He blames Earth's advancement into space for his planet being sealed off by the Sphere and for the loss of a woman he loved — his wife.
Sawa Kaizaki
Sawa Kaizaki
Portrayed by: Sae Miyazawa
Although she is the pilot and operator of the Nursedessei, the Team’s mobile mothership and anti-monster battleship, she is actually a leading authority on monsters, holding a doctorate in biology.
- Actor Allusion: Her first name is a reference to her actress' previous role in Ultraman Saga as a defense force member also named Sawa.
- A Day in the Limelight:
- She is the main focus of #10 due to Neomegas involving her mentor and their differing beliefs.
- She gets major focus again in #20, alongside Kirino, as she and her fellow GUTS-Select member investigate the Ragon situation and bond with Urasawa.
- Fictional Field of Science: She has a degree in biology on the subject of monsters and is a leading authority on them.
- Humans Are Flawed: This is the best way to describe her view on humanity's relationship with monsters, as while she believes that humanity should coexist with monsters instead of killing or enslaving them, she admits that coexistence may not be possible or plausible in the near future, and the best she can do now is to minimise the conflicts between humans and monsters.
Taiji Murahoshi
Captain Taiji Murahoshi
Portrayed by: Masaya Kikawada
As monster attacks became rarer, he left the front lines to work as the principal of the Terrestrial Peaceable Union (TPU) training school to raise new recruits, but after the Sphere invasion he returned to the field as a new captain. Now he commands the team tasked with defending the Earth.
He has a calm personality, always bright and smiling, but he is strong to the core. He takes off his glasses when angry, but never loses his smile. His wish is to protect the countless “precious things of the people” of Earth.
- Ace Pilot: He once worked as a GUTS Select pilot but had a brief retirement to function as the Captain of the team in the years of peace. He goes back to his pilot role in episode 2 to fight Deathdrago and even gets to snap off one of its horns like Chairman Shizuma had done so against the first.
- Chef of Iron: Episode 9 reveals him to be one when he cooks for Grace and his daughter after learning of their poverty, and he mentions he regularly cooks for GUTS Select.
- The Glasses Come Off: As he always smiles and never loses his cool, this is the only indication that he's upset, best shown when he removes his glasses and calmly explains why he's disappointed with Ichika's poorly thought-out actions in Episode 5.
- Not So Above It All: The finale has him flabbergasted when Kanata and Kengo casually reveal Kengo's identity as Trigger to him, after keeping it a secret for the majority of the series and deliberately stalling out the reveal during Kanata's own reveal of his identity just to see his and Sawa's reactions.
- Rank Scales with Asskicking: Being GUTS-Select's captain and Tatsumi's successor, Murahoshi is very much experienced even on the frontlines and a very capable pilot to boot.
- Reasonable Authority Figure: His priorities lie heavily on the side of protecting civilians, so when he sees Kanata nearly get himself killed taking up a weapon to try and defend people from the Spheres he prevents Ryumon from accosting him and suggests to him that he should join up with the TPU if he has the will to protect people.
HANE2/Hanejiro
HANE2/Hanejiro
Portrayed by: Hiroshi Tsuchida (voice)
- Ace Pilot: An AI example, it pilots the GUTS Hawk and proves capable enough with it to fend off Deathdrago. Episode 3 reveals it can pilot both the GUTS Falcon and the GUTS Hawk at the same time, which comes in handy whenever Kanata needs to transform into Decker. In Episode 4, it manages to combine both jets into the GUTS Gryphon on its own and deals the killing blow to Mons-Ahgar in combination with Decker.
- Aw, Look! They Really Do Love Each Other: He might be exasperated by Kanata's antics and frequently act snarky at the latter's expense during the Dimension Card segments but genuinely cares for the new recruit, better demonstrated when he rushes to save Decker from Neomegas in episode 10.Hanejiro: KANATA!!!
- Closest Thing We Got: With the Terraphaser's initial AI fried by Raibasser's lightning, Hanejiro was installed as its new AI due to being the only AI on hand along with having the combat experience to fight against the kaiju despite being designed for piloting planes.
- Composite Character: While it's mainly based on Hanejiro, it also takes elements from PAL for being an AI companion with a masculine voice that helps Kanata fly the GUTS Falcon when he's transformed into Decker.
- Contrasting Sequel Protagonist:
- To the original Hanejiro: Both are yellow robotic critters who act as the team's mascot. But Hanejiro was mostly childish in personality and looked like a plushie who didn't see much if any action on the battlefield, HANE-2 on the other hand acts like an adult and fights in the open as a pilot, is very snarky when need to and looks more akin to a mini-mech.
- To Marluru: Like the Hanejiro example, they're both the Team Mascot-of-sorts, but while Marluru was a child with knowledge on aliens who cooperated with Akito in developing weapons and equipment, HANE-2 is an Ace Pilot who works more closely with Kanata and Captain Murahoshi. Furthermore, Marluru was unaware of Kengo's identity as Trigger while Hanejiro is Decker's Secret-Keeper.
- Heroic RRoD:
- He ends up overheating when piloting Terraphaser for the first time, which is not helped by the fact he was not designed to pilot it.
- Gets an even worse one after Asakage hijacks Terraphaser's control from him by force in episode 14, even in the next episode Hanejiro is left completely malfunctional and out of commission for the entire two-parter.
- Homage: Serves as one to Hanejiro, though more robotic in appearance and capable of speech. It even shares the former's role as the titular Ultraman's Secret-Keeper.
- Not So Stoic: It first appears to be a polite, if emotionless AI unit, but its interactions with the other members of GUTS Select gradually reveal it to possess human-like emotions and be capable of more casual-sounding speech, even getting quite snarky when interacting with Kanata.
- Only One Me Allowed Right Now: Can Body Surf between the module on the Nursedessei or the one in the GUTS Hawk.
- Ridiculously Human Robot: Hanejiro is capable of human-like emotions and often interacts with Kanata in a casual manner. Episode 11 shows he even gets dizzy when the team carries him and throws him like a rugby ball while running towards the downed Terraphaser. He himself is aware of this, and tells Kanata in Episode 12 that he's becoming more human by interacting with him.
- Secret-Keeper: Learns Kanata's identity as Decker in Episode 3 but keeps quiet at his request going as far as archiving the data so he won't let it leak by accident. Episode 12 shows he's used this valuable position to create situations that allow Kanata to transform, such as forcibly ejecting him from the GUTS Gryphon or letting Terraphaser fall on him to hide his transformation.
- Team Mascot: Hanejiro acts as the team's sort-of-mascot, being their "cute" sidekick, though he's far more serious than the usual examples, especially compared to the original Hanejiro of Dyna.
- Vocal Dissonance: It looks like a small, rotund robot designed after the soft-voiced Hanejiro, but speaks in the voice of an adult man. However, it does occasionally emit a digitised version of the original Hanejiro's high-pitched "Pamu!" vocalisations.
- Voice Changeling: Episode 4 reveals it can replicate Kanata's voice to talk to his teammates to avoid suspicion. However, while it has Kanata's voice, it doesn't talk like him at all, much to Kanata's chagrin.
Mecha
GUTS Hawk
GUTS Hawk
GUTS Hawk
GUTS Hawk and GUTS Falcon combined to form GUTS Gryphon
An unmanned fighter initially created for space exploration. but after the attack of the Spheres was modified into a fighter plane to combat the new threat.- Combining Mecha: It can combine with the GUTS Falcon to form the GUTS Gryhpon.
- Multiform Balance: Its Dragon Mode has much greater speed than its Flight Mode at the cost of using its cannons as thrusters.
- Red Is Heroic: It's primarily colored red and is modified to fight against the threat of Spheres and other kaijus.
Terraphaser (Unmarked Spoilers)
Terraphaser
Summon: Terraphaser!
A giant robot codenamed DG001 and the the pinnacle of TPU's technology. Its strength makes it a great addition to GUTS-Select's arsenal to combat against the threat of monsters... Or so it appeared to be, as it turns out its true purpose was to aid the evil Yuichiro Asakage/Agams the Bazdor in helping the Sphere destroy Earth after Agams reveals his true intentions he takes over as its main pilot and repeatedly uses the robot against GUTS-Select, intending for it to be a keystone of his ultimate plan.- Ambiguously Related: As Marlulu and Hotta note in a Special Episode, it is very similar to the Deathfacer created and used by the Alien Monera from Dyna with them outright wondering if the designer somehow got information about the alien race.
- Boss Subtitles: "Cybernetic Golem".
- Chest Blaster: By folding the armor on its shoulder, it forms the TR Mega Buster on its chest capable of obliterating Kaiju with one shot.
- Composite Character: Is primarily a Deathfacer homage, but its role in the endgame and name are also taken from the Terranoid/Zelganoid, who is also a Sphere-powered mecha made to put humanity on the same level as Kaiju and Ultras while harboring a sinister nature underneath.
- Contrasting Sequel Main Character: It contrasts the SAAG units used by STORAGE from Ultraman Z. Since while the SAAG units are more down-to-Earth and more realistic mecha such as being hard for humans to pilot and having a limited amount of energy to use. Terraphaser is a more fantastical mecha that lacks the weaknesses of the SAAG units due to being powered by TR particles and controlled by AI units instead.
- Dark Is Not Evil: Is colored a pitch black and has a fierce-looking red eye but it is a force of good under GUTS Select's custody. But it winds up subverted when Agams takes it over and it becomes an antagonistic force for the rest of the series. It then becomes double subverted after Agams' redemption and then death as the former uses it to fight Mother Spheresaurus and in the finale Hanejiro uses it for that same purpose, now rid of the Sphere's evil influence.
- Death Is Cheap: No matter how many times it gets destroyed, Agams can bring it back using the Phase Riser and Terraphaser's Mons Dimension card, all thanks to its Sphere-powered nature. Even Agams' death isn't the end of Terraphaser as the Phase Riser remaining intact allows GUTS-Select to reactivate it for Hanejiro to use.
- The Dreaded: Murahoshi speculates that Terraphaser's sheer strength and technological powers is what causes several monsters to awaken and attempt to destroy it similar to what happened with the Ultroid Zero in Ultraman Z. However, episode 22 would reveal that it was actually because of it being powered by Sphere energy.
- Evil All Along: Unsurprisingly for a Deathfacer homage, it was never built for the purpose of protecting Earth, but for Agams to kill Decker and help the Spheres destroy Earth. Episode 22 reveals that it's powered by the Spheres' energy. Then this eventually becomes subverted when Agams redeems himself and sacrifices himself leaving the mech back into GUTS-Select hands again.
- Evil Costume Switch: After Agams takes over, its face also changes to a more demonic looking one.
- Evil Sounds Deep: When under Agams' control, it makes a low-pitched groan reminiscent of Jamila's roars alongside its usual digital beeping sounds.
- Expy: Of King Joe STORAGE Custom as a heroic version of a usually malevolent mecha employed by the attack team as the pinnacle of their weapons' development. Kanata even gives a Continuity Nod of King Joe crash landing on their Earth when they were kids, which is about 10 years ago in the continuity (during Ultraman Trigger: New Generation Tiga) and shows that it was also deliberately modeled after King Joe SC in-universe.
- Face–Monster Turn: Becomes an enemy when under Agams' control. It leaves this role in episode 24 when Agams uses it to destroy the Sphere Barrier after his own redemption.
- Fun with Acronyms: Inverted since there is nothing fun about the acronym of its codename, with Marlulu theorizing if the DG stands for Decker Genocide after Agams shows that the mechs true purpose is to kill Decker and commit genocide on humanity.
- Homage: To Deathfacer, the robotic servant of Queen Monera and one of the antagonists of Ultraman Tiga and Ultraman Dyna: Warriors of the Star of Light as a robotic machine that starts out as a force of good before it is hijacked by aliens to be a tool of evil and is even revealed to have been made from the start with the intention of helping out the invaders in the first place.
- Homing Laser: With the TR Particles, it is able to bend it laser attacks to catch opponents off-guard.
- Humongous Mecha: A 69 meter (226 foot) tall mecha, whose development restarted due to the threat of the Sphere.
- Motion-Capture Mecha: Agams controls Terraphaser this way, using a special cockpit feature he had secretly installed that lets him use his own nervous system to control Terraphaser's every move.
- Mythology Gag:
- Deathfacer was originally made by TPC as a battleship known as Prometheus before the Monera hijacked it to become a death machine, here it is a TPU creation for good and starts out in its robotic form. And it later turns out to have been made for evil from the start once its true mastermind hijacks it.
- When controlled by its original AI unit, its face is devoid of any features, which gives it a resemblance to Beatstar, whose suit was modified from Deathfacer.
- Power Copying: Once Agams takes over, he's able to his own Mons Dimension Cards with his Phase Riser to let Terraphaser channel the depicted Kaiju's power through its Arm Cannon. So far, he's used the Mons Dimension Cards of Gomora, Eleking, Neomegas, and Mons-Ahgar.]
- Shout-Out: It utilizes special energy particles named TR particles to fly and power its energy weapons, which is a reference to the GN particles from Mobile Suit Gundam 00.
- Taking the Bullet: Agams uses it to shield Decker from the Mother Spheresaurus' attack in episode 24, the attack ends up killing Agams in the process while vaporizing all of Terraphaser but the Phase Riser.
- Unskilled, but Strong: While it's equipped with powerful weapons, the AI unit designed for it is lacking in combat experience, which allows Raibasser to deactivate it. After the AI unit is replaced with Hanejiro, it becomes much more skilled in fighting capable of using its flying capabilities and beam attacks to great effect. Agams takes this further as he proves even better with it than Hanejiro, being capable of beating Decker with ease.
- Worf Had the Flu: Loses its first battle against Raibasser because of the original AI unit lacking combat experience and is unable to finish the second battle due to Hanejiro overheating before delivering the final blow.
- Worf Effect: It was able to defeat Decker in all three of his forms, but when Decker transformed into Dynamic Type, it got completely trounced and eventually destroyed for the first time.
Allies
Senior members of GUTS-Select
The previous members of GUTS-Select, who due to the lack of monsters on Earth went out to explore space, only to end up trapped offworld after the attack of the Spheres. They then took it up themselves to protect the Mars colony from further Sphere attacks.
See their page here.
See their page here.
- Badass in Distress: In his second appearance, Kengo ends up captured by the Spheres, who probe his memories and eventually find the Eternity Core from them, turning its obtention into their new goal.
- Legendary in the Sequel: Their exploits are well-known in Decker with them being known as the team that saved Earth a decade ago.
- Seen It All: In the fourth special episode, when Hotta is panicking that the Spheres are launching an all-out attack that threatens the Earth, Marlulu remains calm since to him this is just the second time Earth is in danger of this scale.
- Trapped in Another World: With the exception of Yuna and Marluru, who are still on Earth, they are all trapped on Mars and are unable to return to Earth due to the Spheres isolating it.
Yuzare II
Yuzare II/Future Yuzare
A mysterious woman who looks like Yuzare who gave Kengo Manaka the Ultra Dual Sword and Dimension Cards cards for some unknown reason.- Ambiguous Situation: Until episode 15, what or who she is, was completely unknown to both the audience and the other characters. Kengo can only recognize that she's not the Yuzare he knows but otherwise has no idea what her deal is and how she is connected to the other Yuzare. In the aforementioned episode 15, Decker Asumi reveals that she hails from the alternate future he came from.
- Identical Stranger: Kengo recognizes her as a Yuzare he doesn't know. She looks the same besides having different clothes and hairstyle. Decker Asumi reveals she's from the future, meaning that she's Yuna's and Yuzare's descendant.
- Vagueness Is Coming: She suddenly appears to Kengo to give him the Ultra Dual Sword, four Dimension Cards and telling him that he needs to go to Earth. At first it appears that Trigger needs to help Decker fight against the resurrected Sphere-Megalothor, but episode 15 would reveal that it actually was in anticipation of Agams revealing himself and his true plans.
TPU Base security robots
Androids developed by the TPU and guard the moon base.
- Face–Monster Turn: They get controlled by Yapool and fought against Kanata and Kengo.
- Mythology Gag: Essentially fill in the role of the Zomborg soldiers of Ultraman Dyna as Mooks of an antagonist in a space base. Up to using nearly the same suit despite being different entities each.
- Reused Character Design: They use slightly altered designs of Khan Digifer's troops from Denkō Chōjin Gridman which were also used for the Zomborg Soldiers from Ultraman Dyna.
- Robot Soldier: Created by the TPU to guard the moon base. They get hijacked by Yapool to be his Mecha-Mooks.
Kaiju and Aliens
Sphere
The main antagonistic faction of the series, an old enemy from the days of Ultraman Dyna, the Spheres return here with the purpose of conquering Earth; for that end they cut off all communication from the planet with their colonies and other planets. To serve their goals, they create various kaiju to deal with enemies or assimilate existing ones.
In General
See Ultraman Dyna for tropes pertaining to the Spheres in general
- Adaptational Badass: They're much more successful in their invasion plans compared to their debut; they take over Earth and Mars in the first episode, which took until the finale of Dyna to happen. Unlike in Dyna where they only created Sphere Synthetic Monsters sporadically, here they remain as a looming threat and are more active in their invasion plans.
- Adaptational Backstory Change: In Ultraman Dyna, the Spheres claimed to be from a warlike civilization whose people assimilated with their own planet to achieve immortality. In Decker, the Spheres are progenies of the Mother Sphere, who sought to assimilate everything for her own greed.
- Adaptation Name Change: Their Boss Subtitles are "Space Floating Object" in this series instead of "Space Orb", which was used in Dyna. The Sphere Synthetic Monsters they create in this series also follow the naming convention "Sphere [name of kaiju]" instead of "Neo [name of kaiju]", likely to prevent redundancy when Neomegas was converted into one.
- Adaptational Superpower Change: In Dyna, the Spheres can reproduce themselves to outnumber their targets and consistently change in designs throughout the series, with their fourth form resembling the first form more than thee second and third. In Decker, they are produced from the Mother Sphere, being transported en masse by bigger King Spheres and not to mention able to swallow humans into their own being.
- Boss Subtitles: "Space Floating Object" for the Sphere in general, "Giant Space Orb" for the King variant, "Dynamic Space Orb" for the Soldiers and the Kaiju they assimilate gain "Synthethic" as part of their pre-existing title.
- The Bus Came Back: The Sphere were last seen in Ultraman Saga in 2012, this series marks their first appearance in 10 years.
- Decapitated Army: The defeat of Mother Spheresaurus signifies the end of their threat.
- The Dreaded: Their sheer presence on Earth is what causes several of the native Kaiju to awaken, while also causing visible distress to them.
- Healing Hands: Episode 11 has Sphere Soldiers demonstrate the ability to heal their Sphere monsters by conglomerating around any parts destroyed or damaged in battle, they can also enhance their allies' body parts as well.
- No Ontological Inertia: All the remaining Sphere dissipate and die when Mother Spheresaurus is destroyed, along with their rebuilt barrier for good.
- Reforged into a Minion: The Spheres can assimilate and enhance pre-existing Kaiju, transforming them into a Spheresaurus-like beast under their control, not unlike the tricks they pulled in Dyna.
- Sickly Green Glow: Unlike the monochrome Spheres in Dyna, the Sphere Soldiers appearing in this series are primarily white with glowing green fissures. This extends to Trigger, whose body glows green when he uses the Sphere Dimension Card to break the barrier and enter Earth.
- Spikes of Villainy: Monsters they create or assimilate gain spikes with their patterns on them.
- Starfish Aliens: They are alien being in the form of well... spheres.
Spheresaurus
Spheresaurus
Dynamic Fusion Monster
The first kaiju of the series, a colossal four-legged beast created by the Spheres to assist in their assault on Earth, it becomes Decker's first opponent.- Aim for the Horn: Decker destroys its horn before finishing it off in the first episode.
- Boss Subtitles: "Dynamic Fusion Monster".
- Came Back Strong: Is resurrected in episode 14 with Neomegas' leftover cells and thus is much stronger than it was before now being capable of overwhelming Decker and Terraphaser and even regenerating its wounds with the help of Sphere soldiers.
- Curb-Stomp Battle: In episode 15, once Decker Dynamic gets through Terraphaser it's killed in one hit.
- EMP: Has one in its back which it uses to deactivate the Nursedessei and GUTS Falcon which were modified in this series to act as drones running on electric energy.
- Fusion Dance: It is created by multiple Sphere soldiers joining together.
- Luckily, My Shield Will Protect Me: It can turn its colossal front legs into a makeshift shield to protect itself from frontal attacks.
- Mythology Gag: Its peculiar four-legged design calls to mind Darambia, Ultraman Dyna's first foe. Its roar is even made by mixing Darambia's roars with Orga's.
- Non-Standard Character Design: It has a pretty unique design compared to most New Generation Kaiju, being four-legged with both its front legs being as big as its own body.
- Starter Villain: The first individual foe Decker faces.
- Starter Villain Stays: It returns in episode 14, stronger than before. Sphere-Geomos summoned another Spheresaurus from the future in Episode 21, and would've summoned another one if not for Dyna killing it while it's passing through the portal.
- There Is Another: According to Decker Asumi, a larger Spheresaurus will appear once the original smaller breed achieved its objective in empowering the Sphere Barrier and draws it closer to the planet's surface. While it only would have appeared in the future originally, Agams' actions ensure that it will come much earlier than it did. Eventually this Spheresaurus would be revealed to be the "Mother" Spheresaurus, whose true nature is that of the Sphere's creator: the Mother Sphere, now taking on a monstrous form for her endgame.
- Top-Heavy Guy: It's an otherwise normally-proportioned kaiju with front legs as big as its own body, giving it a quadruped stance.
Sphere-Gomora
Gomora/Sphere-Gomora
"Ancient Synthetic Monster"
A normally peaceful Earth kaiju that wakes up for unknown reasons and attacks a city in a frenzy, but after its tail gets cut off by GUTS Select it gets turned by the Spheres into a new, stronger form: Sphere Gomora.See Ultraman Tv Series for tropes pertaining to Gomora in general
- Attack the Tail: As a Gomora, its tail was cut off by GUTS SELECT. Unfortunately this leaves it open for the Spheres to assimilate.
- Back from the Dead: It returns by multiple Sphere Soldiers amalgamating into its form in episode 23.
- Body Horror: The Spheres' mutations have caused one of its horns to grow bigger than the other and replaced several of its body parts with Sphere-like structures, which implicitly cause it a lot of pain and distress.
- Boss Subtitles: "Ancient Synthetic Monster"
- Non-Malicious Monster: Its heavily implied that it awoke and attacked due to the Spheres' presence on Earth, as GUTS Select staff note that Gomora is strong but not usually aggressive.
- Super-Strength: It's very physically powerful as a normal Gomora already, but as Sphere Gomora its strength becomes so greatly improved that Decker needs to obtain his Strong form to stand a chance against the kaiju.
- Tail Slap: After being turned into Sphere Gomora, the stub of the cut off tail grew into a short spiked one and uses it in the fight with Ultraman Decker.
- Tragic Monster: It ends up like this once it is assimilated by the Spheres, the transformation is heavily implied to be painful due to its sheer Body Horror and Gomora ends up confused about its new sorry state. Killing it comes across as an act of mercy to its enslaved state.
Sphere-Megalothor
Sphere-Megalothor
"The Evil God (Second Form)"
The evil god that once plunged the world in darkness, now resurrected by the Sphere's power. Within it Carmeara has also revived.
See tropes pertaining Megalothor under Carmeara's folder here.
- Back from the Dead: Both it and Carmeara within it were revived by the Spheres. Though Sawa believes that rather than the Spheres choosing to revive Megalothor, Megalothor regenerated itself using the Spheres. What's also noticeable is the fact that Megalothor lacks "Synthetic" as part of its Boss Subtitles unlike the other assimilated kaiju.
- Boss Subtitles: "The Evil God (Second Form)"
- Clipped-Wing Angel: Downplayed. While she's still shown to be powerful enough to give Trigger and Decker a fight, replacing the Eternity Core's power with Spheres means that Trigger can fight it using its regular forms and the Ultra Dual Sword alongside Decker, with the duo nearly defeating the Kaiju the first time if not for Trigger pausing when he discovers Carmeara was also revived, allowing it to escape.
- Enemy Without: Becomes separate from Carmeara after Trigger, Decker and Yuzare save her. Carmeara then helps obliterate it for good.
Sphere-Red King
Red King II/Sphere-Red King
See Ultraman TV Series for tropes pertaining to Red King in general
- Back from the Dead: It returns by multiple Sphere Soldiers amalgamating into its form in episode 23.
- Body Horror: The Spheres' assimilation caused Red King to essentially explode with spikes protruding throughout its body.
- Boss Subtitles: "Skull Synthetic Monster"
- Composite Character: Has the base mold of the first design of Red King but has the red coloration and larger fangs of the male Powered Red King.
- Mythology Gag: It is killed by being shot through the neck just like how the second Red King in Ultraman had a hydrogen bomb stuck in its throat.
- Red Is Violent: After being assimilated by the Spheres it gains a bright red coloration to compliment its fiercer white eyes and spikes.
Sphere-Neomegas
Sphere-Neomegas
- Aim for the Horn: The GUTS Gryphon breaks its horn during their first battle, only for the Spheres to regenerate it by fusing with its stump.
- All Your Powers Combined: Has abilities akin to previous Sphere monsters, notably is that the Spheres give it Spheresaurus' frontal legs to increase its power.
- Back from the Dead: It returns by multiple Sphere Soldiers amalgamating into its form in episode 23.
- Boss Subtitles: "New Creation Synthetic Monster"
- The Juggernaut: Neomegas was already stronger than the average monster due to its enhancements. It became even stronger after the Spheres assimilated it, defeating Decker in a few moves, plowing through everything thrown at it and forcing GUTS-Select to use Terraphaser against it. Even then it takes a tag-team between Terraphaser, Decker and a ton of TPU soldiers to finally bring this thing down.
- Mix-and-Match Critters: At one point it has the base Neomegas' body, Spheresaurus' frontal legs and Sphere soldier structures all over its body making it resemble a peculiar cross of all three things.
- Sinister Scythe: Its hands are replaced with Sphere-like scythes at several points during its battles.
- Super-Toughness: In its final stand it manages to resist the TR cannon's full power to the point Terraphaser almost suffered a complete meltdown just to finally kill it.
- Top-Heavy Guy: It becomes this when the Spheres give it Spheresaurus' forelimbs.
Galactron MK 2
Galactron MK2
A giant robot collected by the Spheres and controlled.See Ultraman Orb for tropes pertaining to the original Galactron. See Ultraman Geed for Galactron MK2.
- Boss Subtitles: "The Sphere Judgementer", as opposed to the usual "Civil Judgementer".
- The Cameo: While Galactron MK2 is the one that Trigger and Decker fights, the original Galactron's right arm can be seen among the many discarded robot parts littered around the moon base.
Sphere-Geomos
Sphere-Geomos
See Ultraman Dyna for tropes pertaining to Geomos in general
- Adaptational Backstory Change: Unlike the original Geomos being formed by absorbing rocks, here it's formed from a presumed-dead Sphere soldier absorbing the S-Plasma breeder reactor after it was overloaded. Fittingly, its Boss Subtitles are changed to S-Plasma Synthetic Monster.
- Art Evolution: While it has an overall resemblance to Neo Geomos, it features key differences in design such as a shorter neck, lacking a gold coloration in addition to its gray body, the horns are curved downwards and look more like those of a ram, the head is much smaller, its hips have spikes, it has shoulder pad spike armor and structures on its belly absent in either Geomos or Neo Geomos.
- The Bus Came Back: Like Mons-Ahgar and Gregore-Man, Geomos had been absent from the mainline instalments in the franchise since its debut in Dyna making a grand return after 23 years.
- Enemy Summoner: Can summon Spheresaurus from other timelines.
- Mythology Gag: Its status as a new variant of a Sphere Synthetic Monster from Dyna that absorbed a reactor brings to mind Thunder Darambia, another Sphere monster variant that appears to be carrying a substation on its back.
- Not Quite Dead: It started out as a seemingly dead Sphere soldier that a group of scientists tried to use for a new energy source, these experiments caused it to become active again and assimilate the facility and energy they had been developing into a new form.
- Shaped Like Itself: Geomos was already a Sphere Synthetic Monster in Dyna, making its "Sphere" connotation rather redundant.
Mother Spheresaurus (Unmarked Spoilers)
Mother Sphere/Mother Spheresaurus
Portrayed by: Sayaka Ohara (voice)
- Achilles' Heel: The glowing Sphere on her chest is the only part of her that can be damaged, even though it still required Decker and GUTS Select to throw everything they had at it to even crack it.
- Big Bad: The true main antagonist of the series, as she created the Sphere race and the Spheres' ultimate goal is to bring her to Earth to devour it.
- Chest Blaster: She can fire a Wave-Motion Gun from the glowing Sphere on her chest after absorbing Terraphaser's energy, which she repeatedly fires to destroy Terraphaser and force Trigger and Decker out of their Ultra forms.
- Composite Character: While she's the series' version of the Gransphere, as the leader of the Sphere and their progenitor, she also takes elements of Queen Monera, having a similar naming scheme and the shape of her shoulders and horns resembling the mouth at the top of Queen Monera's head along with her prelude being heralded by a robot created to assist her while passed off as a tool of good.
- Curb-Stomp Battle: Defeated Trigger Glitter Eternity offscreen between episode 23 and episode 24, Trigger can barely even move after their battle while Mother Spheresaurus is none the worse for wear.
- Eldritch Abomination: Befitting the head of the Sphere forces it is a demonic creature with an unimaginable nature and origins unknown who is horrific in every aspect of it.
- Enemy Summoner: Can summon Sphere Soldiers and Sphere Kings to aid her in battle.
- Evil Laugh: Her roars contain the distorted sound of a woman laughing, befitting her evil nature.
- Final Boss: In the vein of the Gransphere in Dyna, it is the final threat of the show.
- Hero Killer: Kills Agams after he redeems himself, and managed to destroy Ultraman Decker as well, forcing Kengo to obtain some of the Eternity Core's power to restore Decker.
- Madness Mantra: "All becomes one", which she repeatedly utters as GUTS Select makes a final charge at her.
- Mighty Glacier: When she descends on Earth, she's shown to be slow and lumbering, but her sheer toughness and immense strength allows her to shrug off attacks like nothing and throw opponents around with ease.
- Motive Rant: She delivers one in episode 25 while she attempts to assimilate GUTS Select and Trigger, which is similar to how the Gransphere delivered a similar speech in Dyna's finale.Mother Spheresaurus: All becomes one. All life in all of the universe becomes one. In order to stop sadness and conflict. To exist as individuals creates conflict and makes a future of sadness inevitable. To merge everything and become the absolute being. To become the perfect lifeform. That is the future. One future... One future...
- Mythology Gag:
- When she descends on Earth in episode 24 she appears in the form of a colossal Sphere orb before taking her monster form, said form has similarities to the Gransphere, one of her inspirations.
- She is heralded by Terraphaser's creation and deployment and confronts Trigger and Decker, just like Queen Monera was heralded by Deathfacer and confronted Tiga and Dyna.
- Not-So-Well-Intentioned Extremist: Claims to seek the unification of all living beings to prevent any more pain and suffering for everyone, yet her outspoken desire to become the Ultimate Lifeform proves that for all she claims to have noble intentions, it's just a means to a very selfish end goal.
- One Bad Mother: And how. Once she comes to Earth, Mother Spheresaurus is ready to absorb the planet's energy so it can be assimilated by her creations. Her plan is also to assimilate all lifeforms to become the supreme being.
- Shoulders of Doom: She has massive shoulder structures resembling a cluster of crystals, which highlight her status as the leader of the Sphere invasion.
- Stealth Pun: She's 88 meters tall and weighs 88,000 tons; 88 can be read as haha ("mother" in Japanese) using the Goroawase Number scheme.
- Summon Bigger Fish: The bigger fish in question since she is the Spheres' progenitor, which the Spheres were trying to summon throughout the series.
- Ultimate Lifeform: What she seeks to become by assimilating all living beings.
- Villainous Breakdown: After GUTS Select breaks free from her attempt to assimilate them and Decker erases most of the Sphere Soldier fleet with an energy wave, she's reduced to repeating her Madness Mantra while wildly flinging energy beams around, none of them hitting GUTS Select as they advance to deal the final blow on her.
Dimension Card Monsters
In General
Kaiju allies summoned by Decker via the Mons Dimension Cards with the D Flasher.
- One-Hit-Point Wonder: Unlike previous appearances where they're able to fight for a longer time, here they only have enough energy to perform one special attack before disappearing. This might be tied to Kanata's inexperience, as when the future Decker summons them they last much longer under his command.
- Out of Focus: They stop appearing and being focused on during the second half of the show.
Miclas
Miclas
The first Dimension Card Monster summoned by Decker, a reliable brute-forced oriented kaiju.See Ultraseven for tropes pertaining to Miclas in general.
- Adaptational Badass: Unlike the first Miclas, who was always getting his butt handed to him; and the Maquette version, who started off cowardly; this Miclas is brave from the get-go and strong enough to manhandle Deathdrago with ease and leave it weakened enough for Decker to finish off.
- The Bus Came Back: Miclas' last major mainline appearance was all the way back in 2009's Mega Monster Battle: Ultra Galaxy Legends with a brief cameo in spinoffs of Ultraman Ginga, making it his first major role in 14 years and first physical appearance in 8 years.
- The Worf Effect: Loses to Elly the Eleking in episode 5 to show that brute force alone won't defeat the kaiju.
Agira
Agira
The second Dimension Card Monster summoned by Decker, a horned kaiju that uses all its power in one powerful move per summon.See Ultraseven for tropes pertaining to Miclas in general.
- Adaptational Badass: Unlike the first Agira who took until 2009's Ultra Galaxy Legends (42 years after its debut) to get a major win, this Agira defeats a Telesdon in his first battle.
- The Bus Came Back: Agira's last mainline appearance was all the way back in 2009's Mega Monster Battle: Ultra Galaxy Legends, with a brief cameo in spinoffs of Ultraman Ginga (not released on tv), making it his first major role in 55 years and first physical appearance in 8 years in addition to its first appearance in a television series since 1967.
- Dash Attack: Charges his horn with energy before rushing towards the enemy to hit them with his horn and take them out in one blow.
- Early-Bird Cameo: Makes a background appearance in the second episode when Decker presents the Kaiju cards to Kanata.
- Mythology Gag: It is desummoned in the same infamous "sulking" pose he had during his battle with Imitation Ultraseven in the original Ultraseven series.
- One-Hit Kill: Agira's MO is to appear, rush at the opponent with his horn and obliterate them in one go before being desummoned due to the exhaustion he has from the attack.
Windom
Windom
The third Dimension Card Monster summoned by Decker, a mechanical kaiju with decent power and durability.See Ultraseven for tropes pertaining to Windom in general.
- The Bus Came Back: Technically, Windom appeared in Ultraman Z, but as a robot rather than a proper Capsule Kaiju, with its last proper appearance before that being in 2009's Mega Monster Battle: Ultra Galaxy Legends.
Others
Deathdrago
Deathdrago
The second monster to fight Decker, returning straight from Trigger and Kanata's first opponent as an in-training member of GUTS Select.See Ultraman Trigger New Generation Tiga Kaiju And Aliens for tropes pertaining to Deathdrago in general
- Aim for the Horn: Like the first Deathdrago it has its left horn snapped off; unlike the first Deathdrago, however, it ends up with both horns getting snapped off by the end of the fight.
- Call-Back: Its the third Deathdrago to appear in Trigger/Decker's world and the first one's rampage is brought up when GUTS Select plans to cut off its horns in order to stop its rampage like Chairman Shizuma did years ago. Too bad that doesn't works.
- Continuity Cameo: It appears in Episode 3 as an opponent in GUTS Falcon's training simulation.
- It Only Works Once: The whole "cut off horn to stop rampage" deal fails to work this time and Deathdrago has to be put down in one go.
Bemular
Bemular
A monster appearing in GUTS Select's virtual simulation training as a giant opponent.See Ultraman TV Series for tropes pertaining to Bemular in general
- Continuity Cameo: It appears here as a virtual opponent in GUTS Select's training.
Alien Shaplay
Alien Shaplay
Aliens used as human-sized opponents in GUTS Select's virtual simulation training.See Ultraseven for tropes pertaining to Alien Shaplay in general
- Continuity Cameo: They appear here as human-sized opponents for GUTS Select to train against in a simulation.
- Mythology Gag: A real Alien Shaplay controlled a Bemular back in Ultraman Orb.
Mons-Ahgar
Mons-Ahgar
See Ultraman Dyna for tropes pertaining to Mons-Ahgar in general
- Art Evolution: Has a much brighter skin color than the original Mons-Ahgar. Its legs are also detailed differently than the previous two, and the spikes on its back are smaller.
- The Bus Came Back: Mons-Ahgar last appeared in its debut series in the episode "Fight! Dyna vs. Dyna", aired in 1998, making a comeback after 24 years.
- Civilization Destroyer: A bio-weapon created by an alien race to destroy civilizations, when they try to advance into space.
- Composite Character: This version of Mons-Ahgar combines traits from the two other individuals seen in Dyna; it's a bioweapon controlled by Alien Meranie like the original Mons-Ahgar, whilst its head has a collapsible version of Mons-Ahgar II's shield.
- God Guise: Its capsule was mistaken by locals as a god named Aga Daimyojin when it landed on Earth 1300 years ago.
- Instant Armor: This version can instantly create an electrified armor to protect its weak point from upfront direct attacks. Unfortunately it is useless against feints and cannot form it when it gets stunned.
- Super Smoke: Whilst much like in its debut appearance it's sealed inside a capsule when dormant, here it's stored in a gaseous form and materialises into kaiju form when deployed.
- There Is Another: The Meranie's voiceover advert outright states that the Mons-Ahgar they sent to Earth is just a test product used as a demonstration. The use of the term "series" to describe Mons-Ahgar in particular carries the implications that not only is Mons-Ahgar mass-produced, but variants of the same monster also exist as products sold by the Meranie.
Alien Meranie
Alien Meranie
The unseen creators of Mons-Ahgar, who intended to sell their monster to alien civilizations that desired to destroy fellow emerging civilizations.See Ultraman Dyna for tropes pertaining to the Meranie in general
- Arms Dealer: Created Mons-Ahgar as a war weapon branded as a product goods for use to destroy up & coming space faring civilizations, Earth was an attempted guinea pig to show off its capacities.
- Civilization Destroyer: Indirect example, through the creation of Mons-Ahgar, it's likely they've ravaged their fair share of civilizations.
- Dissonant Serenity: Through the blue capsule containing Mons-Ahgar, they calmly talk about the kaiju like a salesman telling the customer about their product's qualities. Their choice of language in particular implies they view their civilisation-destroying monster as some kind of pest control.Alien Meranie (voiceover): Are you troubled by annoying civilisations that advance into space? Then you need the Destructive Monster Mons-Ahgar Series. These monsters will wipe out any civilisations in your way. This is a demonstration to show you their capabilities. Numbers are limited, so be sure to order quickly.
- Mythology Gag: The Meranie sell Mons-Ahgar units to destroy civilizations, a continuation of the existence of multiple individuals in Dyna. They also are not seen onscreen and their last transmission is from over a thousand years ago, implying they may be long-extinct like their original selves.
- The Voice: Only the voice of an individual promoting Mons-Ahgar is heard, the species is never seen onscreen.
Eleking
Eleking/"Elly"
An Eleking who belongs to an Alien Pitt named Yuko who was stranded on Earth when the Spheres attacked, due to being overfed it develops a gluttonous appetite and grows out of control with the threat of starving driving it to violence.See Ultraseven for tropes pertaining to Eleking in general.
- Adaptation Distillation: Its role in the episode it appears in references nearly all of Eleking's major appearances throughout the history of the franchise.
- Breaking Old Trends: The first Eleking (besides Rei's which did die later on) to survive its debut episode intact and merely gets calmed down.
- Gentle Giant: When not hungry or overloaded it is a sweetheart that loves to imitate its owner's movements and wouldn't harm a fly.
- It Can Think: It's noticeably more intelligent than past Elekings, as demonstrated by its ability to copy other people's movements, which it uses to make Decker let his guard down. It also zaps Decker by electrifying the water he's standing on instead of directly using its tail.
- Mythology Gag: Makes a bunch of references to past Elekings.
- Like the original Eleking, it fights and defeats Miclas while also mainly coming out of a lake and even bothering a fisherman with its presence. Its tadpole stage also makes an appearance, using the design from Ultraman Max.
- One of its growth stages is identical in appearance to Lim Eleking.
- Decker fights it under a moonlit night, the same setting where Ultraman Taro fought Re-Eleking. This Eleking's more comical mannerisms also reference how Re-Eleking tried to impress some kids by doing a cartwheel.
- Like the Eleking in Ultraman Geed it belongs to a benevolent Alien Pitt and isn't aggressive out of anything but hunger, though this one gets to live in the end.
- Non-Malicious Monster: It's not really evil nor aggressive by itself, it just so happens that its hunger that almost starves it drives it to violence when it becomes too much to handle and even that was the result of its owner improperly feeding it. When not hungry it is a very pleasant and nice kaiju. It is for this reason that Decker doesn't kill it, instead reverting it to tadpole form so that Yuko can take care of it properly this time.
Alien Pitt
Alien Pitt/"Yuko"
A benevolent Alien Pitt who was traveling on Earth when the Spheres attacked and wound up trapped with the rest of the planet's inhabitants. She attempts to keep her pet Eleking, "Elly", alive but accidentally causes it to rampage. When trying to fix her mess she meets and befriends Ichika who becomes a big help in calming down her monster.See Ultraseven for tropes pertaining to Alien Pitt in general.
- Trapped in Another World: She got stuck on Earth first by having her ship crash down on it, then even further when the Sphere Invasion enclosed Earth in a barrier.
- Unwitting Instigator of Doom: She overfed Elly out of concern that she might not be giving it enough food, causing it to grow giant and develop a massive appetite along with its hunger becoming gradually too much to handle every time, becoming a threat to the local community. After Decker reverts Elly to its tadpole form, Sawa provides her with a tutorial on proper feeding to prevent a repeat situation.
Underground Monsters
In General
Several subterranean monsters.- Boss Subtitles: All the monsters share the subtitle "Underground Monster" with Twin-Tail, Gudon's natural enemy, even being changed from "Ancient Monster" to this to keep up the esthetic similar to how Ultraman Max gave several returning monsters new subtitles.
- Non-Malicious Monster: They started causing trouble to humanity due to their food source, the Supercritical Metal, being taken by excavation.
- There Is Another: Initially GUTS-Select thought that Pagos is the only monster attacking the city, only for it to turn out that Gudon is the other culprit.
Pagos
A subterranean monster that last appeared 8 years ago, it appeared on the surface to feed on the Supercritical Metal a factory in Sorafune city excavated from its original habitat.See Ultra Q for tropes pertaining to Pagos in general.
- Bizarre Sexual Dimorphism: The golden rainbow that appears before it emerges from the ground is hypothesised to be a mating display by males of its species, implying that the individual appearing in Ultraman Taiga might be a female.
- Gaia's Vengeance: An old lady Kanata talks to as part of his investigation believes Pagos was sent by the gods as punishment for building the factory harvesting Supercritical Metal. She's Right for the Wrong Reasons; while Pagos did appear because of the factory, it's simply because it feeds on the metal and the factory was removing its food source from its underground habitat.
- Mythology Gag:
- Much like its debut in Ultra Q, its appearance is heralded by sazame bamboo blooming and a golden rainbow appearing in the sky.
- Sawa mentions its scientific name of Pagotortoise, which was last mentioned in Ultra Q, and references its debut by stating the oldest records of it showed one appearing in the outskirts of Beijing.
Gudon
A subterranean monster living in the same underground cavern as Pagos, it dragged Decker down into its habitat during his fight against Pagos on the surface.See Return of Ultraman for tropes pertaining to Gudon in general.
- Extendable Arms: Its whips can apparently extend to a length of over 3 km, as it is able to grab Decker at the surface and drag him down to its habitat, which is 3200m underground.
- Eye Beams: It can fire a red beam from its eyes in this series.
- Mythology Gag: The Eye Beams it possesses in this series is a nod to supplementary material stating that Gudon uses X-rays emitted from its eyes to see through rocks.
Telesdon
A subterranean monster living in the same underground cavern as Pagos and Gudon.See Ultraman TV Series for tropes pertaining to Telesdon in general.
- Butt-Monkey: It barely got to do anything before Agira obliterated it with a single Dash Attack.
- Mythology Gag: Its defeat at the hands of Agira references their status as recurring monsters in Ultra Fight, where Agira was the only kaiju Telesdon scored a victory against.
Twin Tail
A colony of subterranean monsters living in the same underground cavern as Pagos, Gudon and Telesdon.See Return of Ultraman for tropes pertaining to Twin Tail in general.
- Butt-Monkey: They get wiped out by the Neo Maxima Nurse Cannon as collateral damage.
- Off-the-Shelf FX: The Twin Tail colony is portrayed by multiple copies of Shonen Rick's X-Plus monster figurines.
- Retcon: Twin Tail's subtitle is changed from "Ancient Monster" to "Subterranean Monster" in this series to fit the theme of the episode featuring monsters with the latter subtitle appearing.
Gijeran
Gijeran
- Botanical Abomination: A colossal flower that spreads its pollen around to put people in a state of bliss.
- Back from the Dead: Yuna reveals that it was initially a fossilized seed that was absorbed into Megalothor's body when it was born, and as a result, was revived with the Sphere's power when it became Sphere Megalothor.
- Composite Character: A mixture of both Juran and Gijera.
- Identical Stranger: Yuna notes that R'lyeh is not the same species as Gijeran, but looks the same because Kengo based the former on the latter due to subconscious memories of the Ultra-Ancient Civilization.
- It Can Think: It's shown to be able to direct people under the influence of its pollen to protect itself, as it does to prevent GUTS-Select from killing it while it grows to giant size. It's also implied that the Lotus-Eater Machine effect is caused by Gijeran using the pollen as a medium rather than it being a effect of the pollen itself, as once GUTS-Select kills it with the herbicide, immediately all the affected people snap back to normal.
- Mythology Gag: It's defeated the same way as Juran in Ultra Q: via a special herbicide mixture fired at it.
Gregore
Gregore "Grace"
See Ultraman Dyna for tropes pertaining to Gregore in general.
- Actor Allusion: He's portrayed by a veteran suit actor, Koji Nakamura, who had been in charge of playing the role of Tiga, Dyna and Gaia and other characters in the TDG trilogy (Tiga, Dyna, Gaia). Here he is an Ultraman-like alien who has long since left his glory days of fighting, not unlike his actor's former position as the main Ultra's suit actor.
- Adaptational Heroism: Unlike the original Gregore, he doesn't fight a kaiju solely to show off his strength, but to protect the people being endangered by its rampage. As if to reflect his nobler qualities, he gets a rise scene when he grows giant to fight not unlike the Ultras.
- Adaptational Nice Guy: He does not imitate this series' Ultraman to become famous unlike the original Gregore.
- Badass Creed: Fitting his status as an alien wrestler, he has one which he recites before he starts a fight."I am the strongest martial arts champion in the universe...the Steel Phenomenon, Grace! Begin the three count of doom!"
- Big Damn Heroes: He reappears along with Nigel in Ultraman Decker Finale: Journey to Beyond to save GUTS-Select from Gibellus, even getting to show off his shapeshifting skills by disguising himself as an Alien Pedan to infiltrate Gibellus' lair.
- The Bus Came Back: Wasn't seen ever since its debut episode in a mainline instalment, his reappearance happens 24 years after his last outing (coincidentally in the same episode the similarly returning Mons-Ahgar also last appeared).
- Everyone Has Standards: He may want a duel with Decker for the sake of reliving his glory days but he won't take extreme actions to ensure so and reprimands his daughter for trying to blackmail Kanata with photographic evidence of his secret after discovering his identity.
- Gender-Blender Name: Grace is traditionally a female given name, though it's possible that it doesn't carry the same connotations on his home planet.
- Good Parents: Other than being a reputed space fighter, Grace also treasures Mika as a family member. While he is willing to personally fight monsters and endanger his life just to impress her, he is not above reprimanding her for doing immoral habits such as blackmailing even if they're for his sake.
- Heroic RRoD: After helping defeat Sphere Red King he winds up comatose for some time before he recovers.
- Kill Us Both: Attempts this Heroic Sacrifice by holding Sphere Red King in place for the GUTS Gryphon. Fortunately Decker summoned his three Dimension Card Monsters to pull him away at the right time.
- Mythology Gag: He performs the same stance as the original Gregore in Dyna when fighting against the rampaging Red King.
- Sacrificed Basic Skill for Awesome Training: He mentions that as a result of training his entire life to become the greatest martial artist, he's not good at normal jobs, causing him and his daughter to live in constant poverty.
- Secretly Dying: His constant bouts in his youth caught up to him as chest pains and say that he doesn't have long to live which he hid from his daughter.
Mika
Gregore "Mika"
The daughter of Grace who is eager to help her father relive his glory days.- Dissonant Serenity: She treats blackmailing Kanata to fight her father as Decker by threatening to reveal his secret identity as a simple transaction rather than the grave act it is.
- Daddy's Girl: She adores her father and wants to make him happy at all costs, even nearly blackmailing Kanata to force him to fight her father.
- Expy: She's one to Kudou Natsumi, the girl who took photos of Asuka slacking off to blackmail him in Gregore's debut episode in Dyna.
- Missing Mom: Her mother is not seen, nor does she allude to what happened to her.
- Trapped in Another World: She and her father were trapped on Earth when the Sphere attacked and enclosed the planet in a barrier.
Neomegas' Victims
Sadora and King Guesra
A Sadora and a King Guesra that wind up brutalized and killed by Neomegas as a show of the kaiju's power.- Death by Cameo:
- King Guesra only has a few minutes of screentime in the opening scene before having Neomegas' Breath Weapon fired down its throat until it dies.
- Sadora has it worse as it appears solely through in-universe archived footage depicting Neomegas tossing its corpse aside after killing it offscreen.
- Mythology Gag: The choice of Sadora as one of the two kaijus Neomegas kills is likely a reference to Clone Sildron being one of the kaiju test subjects appearing on Neosaurus' island, as both Sadora and Sildron have pincers for arms.
- Shout-Out: King Guesra is killed the same way the Female MUTO is killed in Godzilla (2014): Having a Breath Weapon fired down its throat as a finishing move.
- The Worf Effect: They only exist to prove that Neomegas can defeat the average Ultra Series kaiju with ease.
Neomegas
Neomegas
- Boss Subtitles: "New Creation Monster", and "New Creation Synthetic Monster" as Sphere-Neomegas.
- Breath Weapon: It has a powerful blue-colored mouth beam which can blast enemies apart with ease, anytime it is about to be used the chest cavity of Neomegas will glow blue.
- Came Back Strong: Returns as Sphere-Neomegas and was strong enough to beat Decker.
- Composite Character: Is primarily inspired on Dyna's Neosaurus but also has the face and body type of the Grigio kaiju as a result of being portrayed by a modified Grigio suit.
- Defiant to the End: Even as it starts being obliterated, Neomegas won't just let up and tries to bring down Decker with it by biting on the Ultraman's arm as it starts to explode.
- Homage: To Neosaurus as an artificial brute monster created by an insane scientist in an attempt to create the ultimate weapon, whose power is tested out by fighting and defeating other kaiju. Its design is in itself a massive reference and homage to Neosaurus as well.
- Hybrid Monster: Like Neosaurus, it was created by modifying an unknown base kaiju via genetic splicing with other kaiju's DNA.
- Intimidation Demonstration: Shigenaga controls Neomegas to defeat Sadora and King Guesra as a display of the potential of her kaiju-controlling technology, with the intent to sell the tech to countries and businesses interested in her research.
- Lightning Bruiser: At first it appears to be a Mighty Glacier with sluggish but strong moves, then when its control and power dampener are destroyed it switches its fighting style to a quick paced and still strong brawler who easily overwhelms Decker.
- Mythology Gag:
- Its Breath Weapon's attack is indicated by its chest orbs beginning to glow, referencing how Neosaurus' Helix Beam was fired from its chest.
- It fights and is defeated by Strong Type, as the original Neosaurus was.
- Much like Grigio Raiden, which its suit was modified from, it was discovered 10 years prior to the series and used as a test base for humans to develop weapons against other kaiju.
- Power Limiter: The bead collar Maki used to control it served as a power dampener as well, preventing its full might from being unleashed on a fully savage and uncontrollable beast. When it gets destroyed it stops being a slow and hard-hitting kaiju, instead becoming a fast and still strong beast that can wallop Decker with ease.
- Red Is Violent: Its body is adorned with bright red parts and as a homage to the highly aggressive Neosaurus of Dyna, it is one of the most violent kaiju of the series, even before its control was destroyed.
- Shout-Out: Twofold to Godzilla. Its Breath Weapon is colored bright blue like the monster's iconic Radioactive Breath, with its charge indicated by certain organs lighting up and it kills King Guesra the same way Godzilla killed the Female MUTO in the 2014 film: By firing its beam down the creature's throat.
- Spikes of Villainy: A violent and deadly kaiju adorned by several spikes through its body; with patterns and colors inspired by the similarly aggressive Neosaurus.
- Taking You with Me: When Decker starts to destroy it, Neomegas tries to bite down his arm as it begins to explode in an attempt to take the Ultraman down with it. It fails.
Gazort
Gazort
A strange kaiju that had previously menaced not only Decker's Earth but also the Neo Frontier Universe's own Earth. It targets the inactive Terraphaser in its first deployment.For tropes pertaining to Gazort in general see Ultraman Tiga
- Ambiguous Situation: Both Captain Murahoshi and Sawa can only speculate and try to guess why Gazort attacked, owing it to Terraphaser somehow being threatening to the kaiju. Episode 22 would eventually clarify why: Terraphaser was partly made with Sphere energy and thus the kaiju recognized it as the actual threat it was.
- Evil-Detecting Dog: Episode 22 retroactively reveals that it felt the Sphere energy within Terraphaser and attacked it so it wouldn't go online and eventually threaten Earth.
- Mythology Gag: Its reappearance here serves as a nod to the fact that Gazort was meant to return in episode 19 of Ultraman Dyna but was left out as all the Clitters left Earth midway through Tiga.
- Non-Malicious Monster: Episode 22 reveals it to be one retroactively as it only aggressively attacked Terraphaser because it could sense the Sphere energy within it.
- Villain: Exit, Stage Left: It escapes its scuffle with GUTS Select and is last seen turning into a cloud of Clitters, with the rest of Episode 11 being dedicated to Raibasser as the main threat of the episode.
Raibasser
Raibasser
"Lightning Bird Monster"
A golden-colored variant of Basser who appears to target Terraphaser and destroy the robot.For tropes pertaining to Basser in general see Ultraman Orb
- Ambiguous Situation: Like Gazort, its motives to attack Terraphaser aren't well-defined but the characters speculate that it did so out of fear of the robot's power. Episode 22 would eventually clarify why: Terraphaser was partly made with Sphere energy and thus the kaiju recognized it as the actual threat it was.
- Boss Subtitles: "Lightning Bird Monster".
- Evil-Detecting Dog: Episode 22 retroactively reveals that it felt the Sphere energy within Terraphaser and attacked it so it wouldn't go online and eventually threaten Earth.
- Homage: With it being an avian kaiju with a golden-colored coat of feathers and a crown-like head crests, it greatly resembles the Dyna monster, Dexador, in addition to being a variant of the Basser monsters introduced in Orb.
- Non-Malicious Monster: Episode 22 reveals it to be one retroactively as it only aggressively attacked Terraphaser because it could sense the Sphere energy within it.
- Shock and Awe: It can fire powerful electric beams from its body to fight foes with.
- Shout-Out: With its storm and lightning powers along with a golden coloration it bears more than a passing resemblance to King Ghidorah.
- Thunderbird: It's an avian kaiju whose appearance is heralded by a thunderstorm, bringing to mind this trope. By basing it on a creature from Native American mythology, it also references how Dexador, the Dyna monster it's a homage to, was sealed within geoglyphs in South America.
Hinabasser
Younger versions of Raibasser that work alongside their larger relative to bring down Terraphaser.- Ambiguously Related: It's unknown if the Raibasser leading their flock is their biological parent, a surrogate adult taking care of them or just an unrelated individual who they follow.
- Enfant Terrible: Just the chick stage of Raibasser and still plenty aggressive.
- Kidnapping Bird of Prey: In place of their larger member's lightning powers, they opt to just grab people and snatch them away before dropping them to their doom. Kanata is almost taken this way but breaks free by transforming into Decker once he's high up enough to not be seen.
- Klingon Promotion: Supplementary material states that most Hinabassers rarely grow up into adult Raibassers, those who do must turn to a fully vicious lifestyle beforehand
- Mooks: A bit more durable and competent than the usual examples but they fill this role as Raibasser's troops to fight the human-sized GUTS Select members.
- Mythology Gag: Their nature as raptorial human-sized monsters brings to mind the Shibito variant of Zoiger.
Noiseler
Noiseler
One of many kaiju awakened by the Spheres' activities.See Ultraman 80 for tropes pertaining to Noiseler in general
- Breaking Old Trends: The first Noiseler to be outright killed instead of being spared as it happened in Ultraman 80 and Ultra Galaxy Fight: The Absolute Conspiracy.
- Eye Beams: Noiseler can fire beams from its eyes in this series.
- The Worf Effect: It is easily killed by Decker and Terraphaser to showcase how powerful the duo is.
Pandon
Spinnie/Pandon
One of Ultraseven's most infamous foes. It first appears as a small creature known as "Spinnie", but as it absorbs energy, it gradually grows and evolves into its adult stage.See Ultraseven for tropes pertaining to Pandon in general.
- Breaking Old Trends: This is the first time Pandon has appeared as a wild kaiju in the franchise, as all previous major appearances of the normal Pandon variant have been pets to alien masters.
- Death Glare: According to Kanata, its eyes remind him of Agams' crazed expression.
- Energy Absorption: Can drain energy from a special meteorite's site to grow bigger and stronger. It uses them first to gain fire powers, then to grow a second head, followed by growing into its adult stage, Pandon, and finally empowering itself against Decker Dynamic Type.
- Flying Face: Spinnie starts off as a floating head before it absorbs energy to grow into Pandon.
- Retcon: While a baby Pandon was briefly shown in Ultraman Taiga, it's identical in appearance to the adult Pandon save for being palm-sized, unlike Spinnie's appearance as a floating head. However, it could be that the one seen in Taiga is an intermediate stage between Spinnie and the adult Pandon.
Alien Metron
Alien Metron "Nigel"
Portrayed by: Yuko Kaida (voice)
An Alien Metron serving as the director of TPU's Internal Affairs division, they are in charge of questioning Captain Murahoshi out of suspicions of his involvement with Agams.See Ultraseven for tropes pertaining to Alien Metron in general.
- An Alien Named "Bob": In this case, "Nigel", which also happens to be a Gender-Blender Name of sorts as they're non-binary.
- Badass Bureaucrat: Despite holding a bureaucratic position, they participate in GUTS-Select's raid on Gibellus' lair and are shown to be a capable fighter.
- Big Damn Heroes: They arrive with Grace to save Kanata and Dinas from Gibellus in Ultraman Decker Finale: Journey to Beyond.
- Breaking Old Trends: They're the first non-binary alien in a Ultra Series work. Especially notable as most Alien Metron were male or ambiguous in Marluru's case, with a single female appearing in the Heisei Ultraseven works.
- Inspector Javert: They have well-founded reasons for investigating Murahoshi's involvement with Agams, but Murahoshi is removed from command for the investigations to take place, leaving GUTS Select unable to mobilise when an S-Class Gomess rampages. After Ryumon clears Murahoshi's name, they apologize to Murahoshi for wrongly suspecting him.
- Klingons Love Shakespeare: Much like the original Alien Metron in Ultraseven, they love classical music and order Hanejiro to play some while GUTS Select waits for investigations to finish, waving their hands along to the music as if they're conducting it.
- Non-Human Non-Binary: Neither male nor female, and a notable alien of the series.
- Obstructive Bureaucrat: They temporarily remove Murahoshi from command to carry out investigations, leaving GUTS Select unable to mobilize against a rampaging Gomess S.
- The Spock: They describes themselves as having earned their position as director by being able to make judgements without influence from emotions, and is focused on data and following rules above all else.
Gomess
Gomess (S)
A larger variant of Gomess, it awakened unexpectedly and attacked Komie City while GUTS Select was unable to mobilise due to Murahoshi being under TPU's investigations.See Ultra Q for tropes pertaining to Gomess in general.
- Not Zilla: While Gomess was always this trope thanks to its suit originally being a repurposed Godzilla suit, this incarnation takes it further than usual by having many scenes of its rampage being direct homages to Godzilla (1954).
- Shout-Out: As the episode it appeared in aired near the anniversary of Godzilla (1954), some scenes of its rampage references the King of Monsters' debut:
- The choice of Gomess as the Monster of the Week is due to the original Gomess suit being a modified Godzilla suit.
- It breaks through a few power lines in exactly the same way the original Godzilla did during its rampage against Komie City.
- The turrets at Komie City that fire against it use the same sound effects from Godzilla (1954), complete with the same camera angles.
Yapool
Yapool
Portrayed by: Yasuhiro Kikuchi (voice)
An interdimensional being with a burning hatred for the Ultras, he offered to team up with Agams to defeat Decker.See Ultraman Ace for tropes pertaining to Yapool in general.
- Asshole Victim: While getting assimilated and mind-wiped by the Spheres is hardly a pleasant fate, given his treacherous actions beforehand and his established Resurrective Immortality it's very hard to feel sorry for him.
- Batman Gambit: He commanded Aribunta to attack the city to lure out GUTS Select so that Agams could team up with the Choju to destroy Decker. When Aribunta was destroyed, he exploited Kanata's desire to save Agams to trap him outside Earth, allowing Agams to rampage on Earth without opposition.
- The Bus Came Back: This is Yapool's first physical reappearance in the series since Ultra Fight Victory, while the Yapool Man form's last appearance was in Ultraman Ace, 50 years ago.
- Mythology Gag:
- Much like his subordinate Alien Antira disguising himself as Goh Hideki in Ace, he takes Kanata's form to lure Ryumon and Ichika towards Aribunta. He later takes Agams' form to bait Decker into protecting him, using this opportunity to trap him in a dimensional rift.
- His assimilation by the Spheres and abrupt death at Trigger and Decker's hands references magazine publications at the time Ace aired that stated his Yapool Man form is physically too weak to even overpower a child.
- Shapeshifter Guilt Trip: He takes Agams' form knowing that Decker would attempt to save him, allowing him to trap Decker in a dimensional rift.
- Truer to the Text: He appears in this series using the Yapool Man form seen in the first half of Ultraman Ace as his default form, as opposed to the Giant Yapool form he used in all previous physical appearances outside of Ace which wasn't the Yapool's default form until the Heisei era seemingly retconned it.
- Undignified Death: He gets assimilated and mind-wiped by the Spheres, before Trigger and Decker blasts him to oblivion while he's shambling aimlessly in a stupor. He doesn't even get to finish his dying words due to his Loss of Identity. For the Big Bad of Ultraman Ace and one of the most powerful villains of the franchise, it's quite the embarrassing way to go.Yapool: Yapool may die..."Yapool"? Who is "Yapool"? Who am I?
- Villain Team-Up: With Agams and the Sphere in general, all in order to defeat Decker and destroy Earth. Subverted with the latter as the Spheres assimilated him and wiped his mind.
- The Worf Effect: Episode 19 has him getting assimilated and mind-wiped by the Spheres.
Aribunta
Aribunta
An ant-based Choju under Yapool's command, he used it to team up with Agams against Decker.See Ultraman Ace for tropes pertaining to Aribunta in general.
- Mythology Gag: Much like in its debut in Ace, Decker uses his Miracle Type's Doppelgänger Attack to knock its head against Terraphaser's head, though this time it doesn't die from the attack.
Ragon
Ragon
A mysterious race of fish-like hominids worshiped by the people of Wadatsumi Village in the past, one member of the species appearing to have attacked people involved with demolishing Ama's Arch, the location where villagers worshiped it.See Ultra Q for tropes pertaining to Ragon in general.
- Adaptational Backstory Change: While the other series portray Ragon as nothing more than a naturally-occurring species of Fish People, this incarnation is worshiped as a god named Lord Ragon and outright stated to have come from a mystic world. Sawa references a sighting of them appearing in Innsmouth and speculates that Ragon might be one of the Deep Ones.
- Adaptational Badass: Previous Ragon were far from dangerous or powerful monsters, and often only became threats due to being mutated. This Ragon is extremely powerful without any indication of it being influenced by outside sources.
- Gaia's Vengeance: It's initially shown to have attacked people involved with demolishing Ama's Arch. While the attacks were later revealed to be Urasawa in disguise, the real Ragon later grows giant and attacks Wadatsumi City, using its Breath Weapon to submerge the reclaimed land once more.
- Interspecies Friendship: Urasawa formed a bond with the individual seen in the series. As it was the only living being she considered her friend left alive in the modern day, she tried to accompany it in when it was about to return to its home dimension, but after Decker prevented her from going, the Ragon waved goodbye to its friend one last time.
- Making a Splash: Its Breath Weapon is changed to a powerful stream of water in this series.
- Mythology Gag: It's essentially a stand-in for Digon, a Dyna monster that was a clear Expy of Ragon.
- Physical God: It's worshiped by the locals as a god named Lord Ragon, with its followers calling themselves Ragonites. It more than lives up to this title by being able to flood portions of Wadatsumi City and overpower Decker, and is only pacified by Urasawa performing a ritual dance to appease its anger.
- Place of Power: Ama's Arch, a stone formation that serves as a portal between Ragon's mystic world and the human world, and is a place of worship for the Ragonites.
Chandlar
Chandlar
An aerial monster with a foul attitude, it serves as yet another Earth-born threat to Decker and GUTS-Select.See Ultraman TV Series for tropes pertaining to Chandlar in general
- Adaptational Badass: It's able to fly and breathe fire in this series, abilities which it lacked in previous appearances.
- The Bus Came Back: Chandlar had been absent from the franchise ever since its debut (predominantly due to being little more than a slightly modified Peguila in design) and only had a new version in Ultraman: The Ultimate Hero with a completely new design. This series marks the return of the original version in 56 years since it debuted.
- Butt-Monkey: It's an otherwise normal wild kaiju that Agams controlled to use as a diversion. To add insult to injury, it still doesn't get to fight an Ultra after 56 years of absence, instead getting unceremoniously blown up by the GUTS Gryphon's Gryphon Talon Beam.
- Fake Ultimate Mook: Agams puts a lot of faith in it as part of his plan, but it ends up being little more than a nuisance due to GUTS-Select predicting that Agams would summon a monster. He actually seems rather surprised that Chandlar went down so easily.
- Mythology Gag: Its return as a monster under Agams' control likely makes it a stand-in for Geranda, as both monsters are winged monsters with fire breath serving as a warm-up foe leading up to Deathfacer/Terraphaser, and end up being blown up by the defence team's weapons. Chandlar's Boss Subtitles of "Winged Monster" also sounds similar to Geranda's "Cosmic Winged Skeleton Monster".
- Suspiciously Similar Substitute: Its reappearance in this series has a lot of parallels with Guigass' return in Ultraman Z, as both of them were long-absent kaiju that lost to Red King in their debut in Ultraman, and reappear as side monsters that get killed off by the defense team's weapons.
- We Hardly Knew Ye: Gets obliterated mere minutes after it shows up, with Decker not even being necessary for the battle.
Other Characters
Maki Shigenaga
Maki Shigenaga
Portrayed by: Mami Nomura
- All for Nothing: While her kaiju weapon, Neomegas, was already destroyed by Decker and her data is confiscated and destroyed by the TPU, her weapon would actually be useless against the Spheres due to their ability to assimilate organic beings, which means that all they had to do was wait for the monster to either weaken or die to take it over.
- Broken Pedestal: Is this to Sawa because she wanted to create a monster that she could control, without understanding the grave consequences in doing so.
- Chekhov's Gun: Agams recreates her kaiju-controlling bead necklace and uses it to control Chandlar in Episode 22.
- Expy: Of Professor Otomo from Ultraman Dyna as a disgraced and insane scientist who creates a bioweapon kaiju in hopes of making it the most powerful kaiju to exist.
- Go Mad from the Revelation: According to Sawa, she went mad after realizing just how dangerous kaiju are along with her doubt that humanity are able to combat them with their own power.
- Humans Are the Real Monsters: Her amoral experiments and eagerness to have humanity create destructive bioweapons like her prized Neomegas goes to show that humans can be just as evil and ruthless as the hostile aliens that menace Earth. She especially stands out since the aliens that physically appeared in Decker before her debut were uniformly presented as sympathetic victims of the Sphere invasion with no intent to conquer Earth.
- Just Think of the Potential!: Part of her motivation for creating bioweapons is that she sees potential in the results and would rather not let it go to waste.
- Mad Scientist: She was fired from TPU for doing unethical work with cloned kaiju and later on created Neomegas as a bioweapon for humanity's usage.
- A Pupil of Mine Until He Turned to Evil: Inverted, as she was Sawa's mentor until the latter found out about her unethical work with controlling kaiju and reported her to the TPU, getting her fired as a result.
- Villain Has a Point: As amoral as her actions may be, she rightly points out that the alternative of humans coexisting with kaiju is too idealistic to be realised at the moment. While Sawa agrees with her on this point, she argues that just because it isn't realistic now doesn't mean it can't be realised in the future, and the best thing she can do right now is to minimise the casualties while finding a way for coexistence to be possible.
- Villain in a White Suit: She's a mad scientist trying to create and sell bioweapon kaiju and is dressed in white from head to toe.
- Well-Intentioned Extremist: She believes humanity and kaiju cannot co-exist and thus the fight against their kind is an "Us or Them" scenario, hence her lack of reservations about creating brutal bio-weapons to fight their threat with and ultimately deciding that what can't be tamed must be destroyed.
The Mysterious Man (Unmarked Spoilers)
Decker Asumi
Portrayed by: Masashi Taniguchi
A mysterious man from the "original"/alternate future timeline where the Sphere didn't trap Earth who comes to the present to stop Asakage's plans, and has the ability to transform into Ultraman Decker, much like Kanata does.- Always Someone Better: He's a far more experienced fighter than Kanata and can fight on equal ground against Terraphaser and Spheresaurus without needing the Ultra Dual Sword. The Dimension Card Monsters also last far longer in combat under his command.
- Ambiguous Situation: While Agams claims that he "followed [Agams] to this age", it wasn't clear whether he's from the future or from the past until the next episode.
- Big Damn Heroes: He appears to save Kanata from being killed by Agams after the former as Decker was defeated, he then transforms into Decker to continue the fight against Terraphaser and Spheresaurus.
- But Not Too Foreign: Implied given the spelling. His naming style when converted to Katakana is still read as "Decker Asumi", even though being Japanese means that his given name should be placed *after* the family name (Asumi Decker). Not to mention the word "Decker" is naturally of English origin.
- Casting Gag: Being portrayed by Masashi Taniguchi, the mysterious stranger has shades of Jin Takayama written all over him. Right from the former's smug and self-assured aura before fighting.
- Composite Character: His casual body language and showy fighting style is reminiscent of Gregore/Imitation Dyna, with some of Gaia and Agul's mannerisms mixed in such as the Bring It gesture and the double-punch combat stance. His status as a family member of the protagonist who is responsible for giving him his powers as the series' Ultraman is also reminiscent of Shin Asuka's father, Kazuma Asuka (in Kazuma's case it was revealed in the novel Zero Drive to the Future with only vague hints in prior works).
- Dissonant Serenity: While he does mean well, his body language, both in battle and not, is incredibly casual and he tends to elegantly dodge foes' attacks, which instantly clues Ryumon in to the fact that he's not the same as the Decker they know.
- Kid from the Future: Is a descendant of Kanata from a different future timeline.
- Save the Villain: He urges Kanata to save Agams even after all he's done, in addition to saving the rest of the world from the Sphere.
- Transferred Transformation: When he summons the Ultra D Flasher, the card deck disappears from Kanata's waist and appears on his own, preventing Kanata from transforming into Decker.
- Walking Spoiler: Talking about this guy spoils the fact that: 1) he's the human form of Ultraman Decker and 2) he's Kanata's descendant and fused with him.
Laelia (Unmarked Spoilers)
Alien Bazdo Laelia
Portrayed by: Yuui Fujiyama
- Dead Hat Shot: As she was trying on various hats for a photo shoot with Agams when the Spheres attacked, this is what's left of her when she gets blasted by the Spheres.
- Early-Bird Cameo: She is vaguely named and referenced by Decker Asumi as well pictured in Agams' memories in episodes 13-14, but the extent of her influence on Agams and relation to him are only clarified in episode 22.
- Happily Married: Was in a happy matrimony with Agams, thus her death caused him to snap from the grief.
- The Lost Lenore: Her death greatly affected Agams, who still misses her and on top of his grief motivated him to try and destroy humanity to prevent her death and the fall of Bazdo in the first place.
- Meaningful Name: She is named after a genus of orchids, which lends credence to her beauty.
- Together in Death: Agams' death in the finale allowed Laelia to reunite with her husband at long last, the two are last seen as spirits seeing Kanata off after the defeat of Mother Spheresaurus.
