History Characters / UltramanDecker

* TakingTheBullet: Agams uses it to shield Decker from the Mother Spheresaurus' attack in episode 24, the attack obliterates it completely at last, killing Agams in the process.

* MirrorCharacter: Episode 15 establishes him as this to [[Series/UltramanTriggerNewGenerationTiga Ignis]], while at the same time acting as his EvilCounterpart. Both are HumanAliens 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.

* DeathIsCheap: 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. This luck runs out when the Mother Spheresaurus arrives, as she blasts the robot apart and kills Agams for good.

* FaceMonsterTurn: Becomes an enemy when under Agams' [[VillainOverride control]]. It leaves this role in episode 24 when Agams uses it to destroy the Sphere Barrier after his own redemption.

* FaceMonsterTurn: Becomes an enemy when under Agams' [[VillainOverride control]].

* SummonBiggerFish: The biger fish in question, which the Spheres were trying to summon throughout the series.

The strongest Sphere monster and leader of the invasion, as the progenitor of the Sphere she is called to Earth to devour it as the Sphere Barrier shrinks taking on a monstrous form for her final plan.

* EldritchAbomination: Befitting the head of the Sphere forces it is a demonic creature with an unimaginable nature and a nature too alien for comprehension.

* BossSubtitles: "Cybernetic Golem", a seemingly fitting title for a giant robot that was built to defend humanity. Until Agams overrides it control complete with a more sinister demonic-looking face.

[[folder:Terraphaser ('''Unmarked Spoilers''']]

[[folder:Miclas]]
!!Miclas
The first Dimension Card Monster summoned by Decker, a reliable brute-forced oriented kaiju.

See Characters/{{Ultraseven}} for tropes pertaining to Miclas in general.
* AdaptationalBadass: Unlike the [[Series/{{Ultraseven}} first]] Miclas, who was always getting his butt handed to him; and the [[Series/UltramanMebius 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.
* TheBusCameBack: Miclas' last major mainline appearance was all the way back in 2009's ''Film/MegaMonsterBattleUltraGalaxyLegends'' with a brief cameo in spinoffs of ''Series/UltramanGinga'', making it his first major role in 14 years and first physical appearance in 8 years.
* TheWorfEffect: Loses to Elly the Eleking in episode 5 to show that brute force alone won't defeat the kaiju.

[[folder:Agira]]
!!Agira
The second Dimension Card Monster summoned by Decker, a horned kaiju that uses all its power in one powerful move per summon.

* AdaptationalBadass: 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.
* TheBusCameBack: Agira's last mainline appearance was all the way back in 2009's ''Film/MegaMonsterBattleUltraGalaxyLegends'', with a brief cameo in spinoffs of ''Series/UltramanGinga'' (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'''.
* DashAttack: Charges his horn with energy before rushing towards the enemy to hit them with his {{horn|attack}} and take them out in one blow.
* EarlyBirdCameo: Makes a background appearance in the second episode when Decker presents the Kaiju cards to Kanata.
* MythologyGag: It is desummoned in the same infamous "sulking" pose he had during his battle with Imitation Ultraseven in the original ''Ultraseven'' series.
* OneHitKill: 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.

[[folder:Windom]]
!!Windom
The third Dimension Card Monster summoned by Decker, a mechanical kaiju with decent power and durability.

See Characters/{{Ultraseven}} for tropes pertaining to Windom in general.
* TheBusCameBack: Technically, Windom appeared in ''Series/UltramanZ'', but as a robot rather than a proper Capsule Kaiju, with its last proper appearance before that being in 2009's ''Film/MegaMonsterBattleUltraGalaxyLegends''.

[[folder:Mother Spheresaurus]]
The strongest Sphere monster.

* CompositeCharacter: His casual body language and showy fighting style is reminiscent of Gregore/Imitation Dyna, with some of [[Series/UltramanGaia Gaia and Agul]]'s mannerisms mixed in such as the BringIt gesture and the double-punch combat stance. His status as a family member of the protagonist who is responsible for giving him his powers (in Kazuma's case it was revealed in the novel ''Zero Drive to the Future'') as the series' Ultraman is also reminiscent of Shin Asuka's father, Kazuma Asuka.

[[folder:Terraphaser]]

[[caption-width-right:350:[[spoiler:''Summon: Terraphaser!'']]]]
A giant robot codenamed [=DG001=] and the the pinnacle of TPU's technology. Its strength makes it an great addition to GUTS-Select's arsenal to combat against the threat of monsters.

* BossSubtitles: "Cybernetic Golem", a seemingly fitting title for a giant robot that was built to defend humanity. [[spoiler:Until Agams overrides it control complete with a more sinister demonic-looking face.]]

* DarkIsNotEvil: Is colored a pitch black and has a fierce-looking red eye but it is a force of good under GUTS Select's custody. [[spoiler:Subverted when Agams' takes over.]]
* DeathIsCheap: [[spoiler: No matter how many times it gets destroyed, Agams can bring it back using the Phase Riser and Terraphaser's Mons Dimension card.]]
* TheDreaded: 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''.

* FaceMonsterTurn: [[spoiler:Becomes an enemy when under Agams' [[VillainOverride control]].]]
* FunWithAcronyms: [[spoiler:Inverted since there is nothing fun about the acronym of its codename with Marlulu theorizing if the DG stands for '''D'''ecker '''G'''enocide after Agams shows that the mechs true purpose is too kill Decker and commit genocide on humanity.]]
* {{Homage}}: To Deathfacer, the robotic servant of Queen Monera and one of the antagonists of ''Film/UltramanTigaAndUltramanDynaWarriorsOfTheStarOfLight''. [[spoiler:Also 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.]]

* MotionCaptureMecha: [[spoiler: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.]]

** 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. [[spoiler:And it later turns out to have been made for evil from the start once its true mastermind hijacks it.]]

* PowerCopying: [[spoiler: 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 ArmCannon. So far, he's used the Mons Dimension Cards of Gomora, Eleking, Neomegas, and Mons-Ahgar.]]

* UnskilledButStrong: 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. [[spoiler:Agams takes this further as he proves even better with it than Hanejiro, being capable of beating Decker with ease.]]

* WorfEffect: [[spoiler: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.]]

* AmbiguousSituation: 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.

* AmbiguousSituation: 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.

* ADayInTheLimelight: 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.

* MadnessMantra: 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 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 VillainousBreakdown.

* MirrorCharacter: Episode 15 establishes him as this to [[Series/UltramanTriggerNewGenerationTiga Ignis]], while at the same time acting as his EvilCounterpart. Both are HumanAliens who lost their home planet to an alien invasion, or in Ignis's case, by a certain genocidal Dark Giant. 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.

* TheResenter: Greatly resents Earth and all of humanity due to their expansion being partly responsible for the Spheres taking over his planet as he himself believes.
* SetRightWhatOnceWentWrong: 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.

* TheyDiedBecauseOfYou: A racial example, as Agams blames the entirety of mankind for Planet Bazdo's fall into the Sphere's clutches. Kanata falls into HeroicBSOD whenever he is reminded of this.

* VillainOverride: In episode 14 he hijacks Terraphaser's control from Hanejiro and takes over the machine for his own uses.

* HumongousMecha: A 69 meter (226 feet) tall mecha, whose development restarted due to the threat of the Sphere.

* AdaptationalBackstoryChange: 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 BossSubtitles are changed to S-Plasma Synthetic Beast.

* MythologyGag: Its status as a new variant of a Sphere Synthetic Beast from ''Dyna'' that absorbed a reactor brings to mind [[Series/UltramanGinga Thunder Darambia]], another Sphere monster variant that appears to be carrying a substation on its back.

* ShapedLikeItself: Geomos was already a Sphere Synthetic Beast in ''Dyna'', making its "Sphere" connotation rather redundant.

* HumongousMecha: A 69 meter (226 foot) tall mecha, whose development restarted due to the threat of the Sphere.

* HumongousMecha: A 69 meter (226 feet) tall mecha, whose development restarted due to the threat of the Sphere.

* HumongousMecha: A 69 meter tall mecha, whose development restarted due to the threat of the Sphere.

* AmbiguouslyRelated: As Marlulu and Hotta note in a Special Episode, it is very similar to the Deathfacer created and used by the Alien Monsera from ''Dyna'' with them outright wondering if the designer somehow got information about the alien race.
* BossSubtitles: "Cybernetic Demon", which is rather ironic for a giant robot created to defend mankind. [[spoiler:Until Agams overrides it control complete with a more sinister demonic-looking face.]]
