Ultramen

Ultraman Mebius

Voiced by: Shunji Igarashi (from Ultraman Mebius to Mega Monster Battle: Ultra Galaxy Legends), Jun Fukuyama (from Ultraman Ginga S movie onwards)

The Ultra hero of the franchise's 40th anniversary, Ultraman Mebius is the first Ultra hero of the original Showa universe to appear on Earth since Ultraman 80. He is inexperienced and relatively young compared to his predecessors, but learns about living up to the legacy of the Ultra heroes before him as the series goes on. He takes on the form of Mirai Hibino. Mebius would also have a few appearances in later entries of the franchise.

Action Bomb: The Mebium Dynamite, which he learned from his mentor Ultraman Taro.
Barrier Warrior: Can create a small force field with his hands.
Blade Below the Shoulder: The Mebium Blade is a mix of Type 1 and Type 2. It's also his main ability in Brave Mode.
Dead Person Impersonation: It's revealed in Episode 22 that his human form, Mirai, is actually that of Hiroto Ban, the son of a spaceship captain who had sacrificed his life to rescue the ship in a crisis. Mebius had chosen that form because when he arrived at Earth, he was unable to save Hiroto but also admired his selflessness.
Explosive Punch: The Ultra Lightning Counter, a supercharged punch that results in an explosion capable of taking out more than one Monster of the Week.
Fusion Dance
- Mebius becomes Mebius Phoenix Brave in the series finale by fusing with Ultraman Hikari and the members of GUYS.
The Hero: Duh!
Naïve Newcomer: Mebius is very inexperienced in comparison to previous Ultra warriors, so the series focuses a lot on his development as a hero.
Panthera Awesome: He is designed by Hiroshi Maruyama after Tsushima leopard cat, a feline species in Japan.
Playing with Fire: His Burning Brave mode gives him the Mebium Burst that allows him to create a ball of fire to finish off monsters barbecue-style.
The Power of Friendship: His Burning Brave mode is formed by such. Taken a step further with Phoenix Brave Mode in the Grand Finale.
Red Oni, Blue Oni: Literally speaking, he's the red to Hikari's blue.
Rookie Red Ranger: As stated above, Mebius is pretty new to the whole "Ultra Hero" thing, but that doesn't stop him from trying his best.
Spell My Name With An S: Sometimes called Ultraman Moebius.
Spin Attack: The Mebium Drill Kick, which he learns in Episode 34 in order to defeat Alien Reflect.
Super Mode: Phoenix Brave Form.

Ultraman Hikari

Hunter Knight Tsurugi / Ultraman Hikari

Click ^here for Hunter Knight Tsurugi

Voiced by: Keiichi Nanba

Originally an Ultraman scientist tasked with examining the Aarb for study, Ultraman Hikari became Hunter Knight Tsurugi through his thirst for vengeance when the Aarb were devoured by Bogal. He came to Earth for Bogal and took on the form of Ryu's late hero and previous leader of the GUYS team, Kazuya Serizawa. After the defeat of Bogal, he was healed by the Ultra Mother and freed from his Armour of Vengeance, becoming Hikari again. Afterwards, he would make sporadic appearances in the series, as well as later shows. He also starred in a 3-episode miniseries about his backstory.

Badass Bookworm: He used to be a scientist and still has a knack for it (such as creating the Knight Timbre for Ultraman Victory's use in Ultra Fight Victory and Ultra Capsules of Ultraman Geed), but that doesn't mean he's not a capable fighter (albeit not before he became Tsurugi).
Bilingual Bonus: Hikari means "light", which Ryu had suggested. However, the team finds it to be an unimpressive name.
Blade Below the Shoulder: Largely relies on his Knight Beam Blade, which is similar to Mebius' own blade.
Canon Immigrant: He's the very first blue Ultra to be part of the main Showa canon of the franchise. Until Hikari's introduction, Blue Ultras only existed in other different universes. In the film Mega Monster Battle: Ultra Galaxy Legends, we see more members of his tribe as background extras.
Dead Person Impersonation: His human form, Captain Serizawa, was killed when Dinozaur attacked Earth. However, to Ryu, Hikari will always just be Captain Serizawa.
Expy: He's essentially a M78 counterpart of Ultraman Agul, being a blue-colored Ultra who is initially introduced as a cold, serious Anti-Hero with a Blade Below the Shoulder who is at first disillusioned with humanity and couldn't care less about collateral damage when it comes to fulfilling his mission, which causes him to butt heads with a red-colored, more passionate hero, but eventually matures as a character thanks to the teachings said hero offers him. He also has elements of Agul's human identity Fujimiya by virtue of being a scientist and a Gadgeteer Genius.
Friendly Rivalry: With Mebius. He likes to show up at the last minute of monster battles and steal the victory from him.
Master Swordsman: Whereas most Ultramen rely mostly on martial arts and beam attacks, Ultraman Hikari primarily relies on his Knight Beam Blade to finish off monsters and duel with foes.
My Greatest Failure: His inability to protect Aarb from Bogal, which was what originally transformed him into Hunter Knight Tsurugi.
Ominous Pipe Organ: His leitmotif as Hunter Knight Tsurugi opens with an organ chord, fitting his single-minded desire for revenge. After he regained his heart as an Ultraman, his new leitmotif as Hikari still opens with an organ in the background, but the context makes it a Holy Pipe Organ instead.
Put on the Bus: He leaves Earth in Episode 17 and only reappears in Episode 35 and the finale.

Roaring Rampage of Revenge: Was so consumed by his desire to avenge Aarb as Tsurugi that he never stopped to think about how his actions affected others. Best shown in Episode 7 "Fanton's Lost Item", where he blows up some buildings when he attempts to kill Bogal with his Knight Shoot and shows no regret for it.
Unwitting Instigator of Doom: Believe it or not, Hikari's act of becoming Hunter Knight Tsurugi leads to a young Ultra who admired him now seeing his former idol as a Broken Pedestal, eventually leading to events where he forgoes his Ultraman identity and becomes one of the most despicable villains in the Ultraman history. His name: Ultraman Tregear.

The Ultra Brothers

https://static.tvtropes.org/pmwiki/pub/images/brothers_1.jpg

Tatakau, kiseki no hīrō! ^note

With the 40th Anniversary of the Ultra Series being concluded, it's only fitting that the Ultramen of the past makes a comeback, this time as the mentor, guide, and teacher to their eleventh and youngest member, Ultraman Mebius.The original team of six are now joined by the Leo brothers, Ultraman Leo and Astra, and Eighty, together with Hikari. With the Father of Ultra as their overall leader, now that Earth is facing the invasion of Alien Empera Mebius will need their assistance more than ever.

Badass Crew: A crew consisting of Ultramen can only be this.
Big Damn Heroes: Yes. So much yes. From Ultraman Taro saving Mebius from the first Imperiser (and actually defeating it), to Ultraman Leo giving Mebius some much-needed assistance against Alien Reflect, to Ultraman Jack and Ace stopping the Heavenly Kings from executing GUYS, whenever a veteran Ultra makes a comeback they're bound to perform some epic rescues or assistances.
The Bus Came Back:
- While Ultraman and Ultraseven had returned in shows from the 90s, for the other Ultras like Jack, Ace, Taro, Leo, Astra and Eighty (all whom appeared in video games, toys, miniseries, those music videos from Ultraman Cosmos' movies, etc.) this is their first appearance in a mainstream series. Needless to say, fans are thrilled.
- For Ultraman Ace fans, Yuhko Minami coming back in the same episode guest-starring Ultraman Ace can be considered this as well.
- The episode guest-starring Ultraman 80 brings back the entire class of Sakura-ga-Oka Middle School as well, during a school reunion after the old school lot was to be torn down for a construction project. Much tears and heartwarming embraces abound when Ultraman Eighty, reverting back to human form as the schoolteacher Takeshi Yamato, reunites with and embraces his former students. It also serves as a "Where Are They Now?" Epilogue for the entire class twenty-five years after their last appearance, with most of them working as scientists, office workers, or have since been married.
Cool Old Guy: The Showa-Era Ultramen are well into their fifties and sixties in their human forms, and can still kick plenty of asses.
Mythology Gag: More often than not, the return of original Ultras will have certain plot elements related to their debuts:
- The Father of Ultra arrives to rescue Ultraman Mebius, by removing the petrification process Jashrine had inflicted on the Ultra, much like how the Father of Ultra saves Ultraman Ace from being petrified by Alien Hipporito.
- Ultraseven guest-stars in the episode where Ultraman Mebius gets crucified alive by the Alien, Grozam - a fate similar to what happened to Ultraseven in the hands of Alien Guts back in his show.
- Ultraman Ace saving GUYS from Lunaticks during a battle on the moon, much like how in the original series, Lunaticks is revealed to be the monster who wiped out an alien civilization (specifically, the civilization one of Ace's ex-hosts, Yuhko Minami, belonged to) living on the moon.
- Ultraman Jack showing up to save GUYS from being executed by Deathrem, just like how the original series had Ultraman and Ultraseven saving Jack from being executed by Nackle. And as a bonus, a video store clerk played by Jack's former suit actor even exclaims, "Ultraman has returned!"
- Ultraman Leo, after reducing Mirai Hibino to tears showing him how far he has to go, asks him if his tears can save the earth, the same Armor-Piercing Question Dan Moroboshi once asked Gen Ohtori. He then gets Mirai to do some Training from Hell, the same thing Seven's human form did whenever Leo couldn't defeat the current Monster of the Week.
Small Role, Big Impact: Ultraman Zoffy in the past had arrived to rescue GUYS' Captain Sakomizu from an alien attack. For for the Ultra, it's just routine duty as a protector of the galaxy, but to the good Captain he's inspired by the rescue, so much that he establishes GUYS as a defense team against alien threats.

GUYS (Guards for UtilitY Situations)

In General

The attack team of this series was founded during the Ultramen's absence in case the monsters suddenly returned. As almost every member of the original team was killed when the monsters reappeared, the team of the series are a very inexperienced lot made primarily from random civilians. However, they slowly grow to become a close-knit group of friends dedicated to not being left on the sidelines whenever Ultraman shows up to save the day.

The Main Team

As a whole

Badass Crew: Unlike the other defense teams of the Showa timeline, GUYS has proven themselves to be equals to Ultraman Mebius. Many battles in the series see them play a pivotal role in helping defeat the Monster of the Week more than almost any other entry in the Ultra Series.
Fire-Forged Friends: They all encountered each other by fate during Dinozaur's attack on Tokyo and were asked to join GUYS by Mirai. Dozens of battles later, they've become one of the closest-knit teams the franchise has seen.
Odd Friendship: A tomboyish motorcyclist, a grandstanding soccer player, a hot-blooded defense team veteran, a timid preschool teacher, a medical student/kaiju nerd, and Ultraman Mebius disguised as a human. They may not be the most normal of defense teams, but they're True Companions through and through.
True Companions: Perhaps, the truest companions of all the defense teams.

Mirai Hibino

https://static.tvtropes.org/pmwiki/pub/images/mirai.png

Played by: Shunji Igarashi

The series protagonist, Mirai Hibino is Ultraman Mebius in a human disguise. He is a naive, but warm-hearted and earnest individual who loves everyone equally. Like all Ultramen, he keeps his identity secret from his team, but this changes in Episodes 29 and 30. He transforms into Ultraman Mebius via the Mebium Brace on his wrist.

Aliens Among Us: Since he's Ultraman Mebius in human form.
All-Loving Hero: He's very close with all his teammates (they're all his best friend), treats everybody respectfully, and sees the best in people. Naturally, the bad guys attempt to break his faith in humanity in their schemes.
Aya Jinguji: (bringing Mirai on a "date") Mirai, is there anybody you like?
Mirai: (unaware of the "date") Of course! There's Ryu, there's Captain Sakomizu — I like everyone at GUYS!
The Heart: He was the one who brought GUYS together, after all.
Idiot Hero: Downplayed, he's better described as extremely naive as he doesn't quite understand how things work on Earth.
Meaningful Name: Hibi no Mirai means "Days of Future" in Japanese which he chose when Hiroto Ban's father told him to live out "his days of future" in place of his late son.
Nice Guy: Mirai is as kind and sincere as they get with Ultraman protagonists.

Trademark Favorite Food: Really loves curry.
Transformation Trinket: The Mebium Brace, which is actually part of his wrist. It can also shoot small bolts of energy when needed.
Tender Tears: Mirai sobbed once he found Ban’s watch on the space station where he died. Later when GUYS turned on him under Mefilas’ influence, he bursts into tears and walks away when they point their guns at him. It’s really telling how innocent and softhearted he is despite being an Ultraman.

Ryu Aihara

https://static.tvtropes.org/pmwiki/pub/images/ryu_3.jpg

Played by: Masaki Nishina

The only member of GUYS from the original crew (who were all killed by Dinozaur), Ryu is hot-blooded and rather cold on the outside. Inside, he is deeply passionate of his duties in protecting people from kaiju. He can often be seen reciting the Five Ultra Pledges, something passed down to him by his hero and previous GUYS captain, Kazuya Serizawa.

A Day in the Limelight: "Formation of Our Vows", "The Resurrection of Yapool", and the two-parter "Day of Farewell" and "Flames of Promise".

Hot-Blooded: And how! Marina often refers to him as "a hot-blooded idiot".
Jerk with a Heart of Gold: It's easy to call him out for his rashness and short temper, but he's also extremely devoted to GUYS and deeply passionate about just causes.

Leeroy Jenkins: Occasionally, his Hot-Blooded attitude leads him into this role, like when he attacked Beo while the Alien Mates was in the middle of discussing potential for peace talks with Mirai and enraging the alien.

George Ikaruga

Played by: Daisuke Watanabe

A former all-star soccer player on the Spanish team, George is a somewhat arrogant fellow and something of a loner, but also an excellent pilot and sharpshooter with excellent vision.

A Day in the Limelight: "Reverse Shot", "The Lonely Grandstander", and "Deathrem's Plan".
Berserk Button: He doesn't like it when people call him "Mr. Ikaruga".
Casanova Wannabe: A Running Gag is him attempting to impress various women by pulling out a rose from nowhere. He even once tried to hit on Teppei's mom!
Gratuitous Spanish: He tends to pepper his speech with random Spanish words. Justified as he was formerly a part of Spain's national soccer team.
Improbable Sports Skills: The flames that appear on the ball when he performs his signature Meteor Shot are implied to be him actually setting it on fire with the force of his kick, as smoke can be seen coming off of Mirai's gloves when he nearly caught the ball.
Jerk with a Heart of Gold: Even though he's something of an arrogant loner, he's genuinely a good guy devoted to his team and his job.
Loner-Turned-Friend: A big part of his development is about this, as even when he was a soccer player, he was unpopular with his teammates for his "lone wolf" attitude in a team game.
Super-Senses: He has above-average sight, allowing him to see fast-moving objects better than the rest of GUYS.
Why Did It Have to Be Snakes?: Despite being a perfectly good swimmer, he's afraid of the ocean. He insists that it's because the ocean has it's own rules, thus not meant for people like him to go to (he said the same about going to space as well), but in Episode 25, it turns out that when he was younger, every time he went to the ocean, something terrible happened to him, so he decided the sea just had it out for him.

Marina Kazama

https://static.tvtropes.org/pmwiki/pub/images/marina_4.png

Played by: Ai Saikawa

Once a motorcyclist with dreams of becoming famous, Marina often acts as a sister to other members of the team — particularly George and Konomi. She also has superhuman hearing which gives her faster reflexes — a trait useful for fighting kaiju.

A Day in the Limelight: "Marina of the Wind", "The Ocean Waves of Time", and "Ace's Wish".
Action Girl: Of GUYS, in comparison to the more timid Konomi.
Cool Big Sis: Plays this role to GUYS, particularly George and Konomi. She's also revealed to have been one to her actual brothers.
Super-Senses: Has highly enhanced hearing, allowing her to pick up on sounds that the rest of GUYS can't hear. However, as a motorcyclist it also distracts her as she gets unnerved if the engine makes even the slightest suspicious noise.

Vitriolic Best Buds: Her relationship with Ryu, as she frequently snarks and rolls her eyes at his Hot-Blooded attitude.
Why Did It Have to Be Snakes?: A minor Running Gag is her arachnophobia. George even uses a toy spider to chase her off when she starts pestering him and gives one for Ryu to use in Episode 25.

Teppei Kuze

https://static.tvtropes.org/pmwiki/pub/images/teppei.jpg

Played by: Kenta Uchino

Medical student and monster maniac, Teppei is the team's tactician and can tell you everything about any kaiju that's appeared in a previous series on sight. Teppei is expected by his incredibly rich parents to inherit his father's hospital — a source of tension for him, GUYS, and his extremely worrying mother.

A Day in the Limelight: "One Path", "Lady of the Blue Flame", and "Mefilas' Game".
Mission Control: Though he occasionally gets to come out with the rest of the team.
Non-Action Guy: Unlike the other male members of GUYS. Teppei is usually stationed at Phoenix Nest, where he communicates strategies and information to his comrades on the field.
The Smart Guy: Both the team's tactician and the one with most knowledge of kaiju.
The Strategist: He comes up with all sorts of odd but clever tactics to counter kaiju.

Konomi Amagai

https://static.tvtropes.org/pmwiki/pub/images/konomi.png

Played by: Misato Hirata

Konomi is a timid, gentle, and hard-working lady who loves animals and children — fitting for a former preschool teacher. Despite her non-combative nature, she has formed a close bond with GUYS' Maquette Monster Miclas, thus making her the team's Maquette user when on the field.

A Day in the Limelight: Is the first member of GUYS to get one in the fourth episode, "Broken Bonds". She gets one in "Konomi's Treasure" and "Immortal Grozam".
Animal Motifs: Rabbits. Other characters have likened them with her timid personality and non-combative role. Helps that the preschool she worked at keeps a bunch of them as pets.
Badass Adorable: She has her moments, such as blowing off Kelbeam's horn in Episode 4 or piloting the Gun Phoenix against Grozam in Episode 46.
Fluffy Tamer: She has the job of managing the Maquette Monsters (mostly Miclas and Lim. Eleking; Windam is much less dependent on her). Miclas is especially dependent on her as it views her as a motherly figure, making her the only one who can command it effectively and give it the courage to fight.

Nice Girl: Easily the second kindest member of GUYS after Mirai.

Shingo Sakomizu

Captain Shingo Sakomizu

https://static.tvtropes.org/pmwiki/pub/images/sakomizu.jpg

Played by: Minoru Tanaka

The captain of GUYS, Sakomizu is an easygoing and wise leader who often drops advice for his subordinates.

A Father to His Men: Especially to Mirai, but he cares about the whole team in general.

Catchphrase: He's always the one who gives the order "GUYS, Sally Go!", usually followed by the team answering with a "G.I.G!"

Cool Old Guy: He's a friendly and laidback guy who acts as a sort of mentor for GUYS, and see Older Than They Look.
Embarrassing Nickname: His friends tend to give him these — Dr. Asami Fujisawa likes to call him "Sako-chan" and Supreme Chairman Takenaka called him "Sakkochi" in front of the team, to his embarrassment!
King Incognito: He's the Chief Inspector of GUYS, but disguised himself as a lowly team captain so that he could directly fight alongside Ultraman.
Mentor Archetype: He's the only one besides Ryu who was part of GUYS prior to the series, so he helps the new members out a fair bit with understanding what it means to be a part of the team.
Older Than They Look: It is revealed in "A Visit from an Old Friend" that he's actually over 70 despite looking to be in his 40s, due to the fact that he was originally a space patrol officer and the effects of light speed travel have slowed his aging.
Reasonable Authority Figure: His laidback and easygoing attitude make him quite approachable for the rest of GUYS. He's also pretty competent when on the field.
Secret-Keeper: Until Episode 29, he's the only person who knows that Mirai is Ultraman Mebius.
Tomato Surprise: He's the Chief Inspector of GUYS.
Trademark Favourite Food: Loves coffee.

Other GUYS members

Adjutant Toriyama

https://static.tvtropes.org/pmwiki/pub/images/toriyama.png

Played by: Kenichi Ishii

The head of GUYS Japan, Toriyama is a cowardly, bumbling sycophant who isn't taken seriously by...pretty much everyone at GUYS.

The Alleged Boss: Despite heading GUYS Japan, no one really takes him seriously, except for perhaps Mirai. But then again, it's not like he deserves to be.
Buttmonkey: Due to his foolish schemes and general bumbling. He's been teleported to Antarctica, arrested by a police officer, had his pants pulled down in public, is constantly embarrassed by his attempts to appear superior to the rest of GUYS, and frequently gets scolded by his subordinates for his laziness and stupidity.
Crouching Moron, Hidden Badass: When push comes to shove, Toriyama proves he can be a competent commander, such as in "The Swordsman From Space" when he directs the mission to destroy Oshima Comet before it impacts Earth and in "Advent of the Emperor" when he stands up for Mirai against the National Security. Additionally, "The Swordsman From Space" shows he's a master of Kendo and loses his cowardice when he's in full garb.
Family Man: Has a wife, children and even a grandchild.

Jerk with a Heart of Gold: As Maru explains in "The Chief Inspector's Message", Toriyama may be a stingy and cowardly oaf, but he cares a lot about GUYS and generally means well.
- Additionally, When Hirukawa's tabloid exposé in "Advent of the Emperor" leads to National Security coming to detain Mirai, he forgoes his usual brown-nosing and refuses to let them throw him under the bus.
Pointy-Haired Boss: It's a good thing GUYS also has Captain Sakomizu and Yuki Misaki though.
Took a Level in Badass: After Mirai's identity as Mebius exposed and National Security comes to take him away, Toriyama of all people looks them straight in the eye and stands up for Mirai.

Secretary Maru

https://static.tvtropes.org/pmwiki/pub/images/maru_5.png

Played by: Yutaka Maido

Toriyama's Beleaguered Assistant.

Beleaguered Assistant: Due to the fact that Toriyama constantly drags him into his dumb schemes, which he is powerless to stop.

Hypercompetent Sidekick: He frequently has to correct Toriyama's statements and deflate his ego when necessary.

Deputy Chief Yuki Misaki

https://static.tvtropes.org/pmwiki/pub/images/misaki_5.jpg

Played by: Saaya Ishikawa

Assistant and substitute of the enigmatic Chief Inspector.

Reasonable Authority Figure: In contrast to Toriyama. She basically acts as the Chief Inspector for GUYS since the real one is nowhere to be found.
Silk Hiding Steel: She's a pleasant and approachable figure, but certainly deserves the respect that GUYS gives her.
Sugar-and-Ice Personality: She usually keeps a professional and collected attitude, even more so than Sakomizu, but as her friend Dr. Asami Fujisawa explained, she also has a smile that can bring courage in even the gloomiest moments.

Kazuya Serizawa

https://static.tvtropes.org/pmwiki/pub/images/serizawa_5.png

Played by: Shin Ishikawa

The original captain of GUYS, Serizawa taught Ryu all about being on a defense team, making him Ryu's mentor and hero. Serizawa is killed in GUYS' first monster battle, but his form is adopted by Hunter Knight Tsurugi.

The Captain: Before Sakomizu was put in the position, he led GUYS and trained them in hopes of creating a defense team that could protect Earth without Ultraman.
Mentor Archetype: Towards Ryu, in the same manner that Sakomizu is towards the rest of GUYS. Ryu also inherited a lot of his ideals as a result.
Posthumous Character: Although he dies at the beginning of the series, his character is highly important to both Ryu and Ultraman Hikari throughout the series.

Chief Mechanic Araiso

Played by: Katsuhiko Watabiki

The mind behind every fighter jet used by GUYS and the previous defense teams, Araiso is a stubborn and crabby fellow whose as passionate about his creations as he is about the lives of the many who have piloted them over the forty years of Ultraman history.

Berserk Button: Never insult any of the fighter jets he's worked on. He will fight you. Seriously, he will. When Ryu derided how the planes of previous series were useless due to how they always crashed unlike the Gun Phoenix, it took all of GUYS to stop the two from brawling each other.
Cool Old Guy: He's a pretty cranky dude, but you gotta give the guy who created every single fighter plane in the Showa Ultra series some credit — he's pretty dang genius.
The Engineer: Comes with being the creator of the fighter jets used by GUYS and all the defense teams before them.
Jerk with a Heart of Gold: He may be a cranky jaded mechanic but he pours his blood, sweat and tears into making the best aircrafts to ensure the pilots have the best chance at coming back alive.

Dr. Asami Fujisawa

Played by: Kei Ishibashi

A friend of Deputy Chief Misaki. Dr. Fujisawa is an utterly brilliant scientist, but also extremely eccentric and playful in attitude. She appears a few times in the series to assist GUYS against major villains.

Bunny-Ears Lawyer: She's described as one of the most renowned experts in the world and having earned her doctorate before she was 20, but you wouldn't know that from her quirky, oddball behavior.

Supreme Chairman Takenaka

Played by: Kenji Sahara

The supreme leader of GUYS and a friend of Captain Sakomizu. He's normally stationed at GUYS' chief headquarters in New York, but he comes over to Japan in Episode 42, marking the beginning of the series finale.

Maquette Monsters

In General

Data-based duplicates of kaiju created from METEOR (Much Extreme Technology of Extraterrestrial ORigin), a technology program that harnesses the technology from failed alien invasions. They are used to assist GUYS and Ultraman Mebius against kaiju, lasting only for one minute before vanishing to recharge.

As a whole:

Hour of Power: The monsters only last for one minute before vanishing. Justified as all METEOR technology is programmed to be active for only only minute in order to reduce the risks of using salvaged extraterrestrial technology.
Mons: Carried over from Ultraseven, but they're digital duplicates of the original monsters instead.
Undying Loyalty: They readily obey GUYS and help Ultraman Mebius battle enemies.

Miclas

Miclas / Eleki-Miclas

First Appearance: Broken Bonds

The first monster selected as a Maquette Monster. Unfortunately, Miclas' natural cowardice proved to be problematic, as he requires an encouraging master to fight. Later on, Miclas would be upgraded with the electrical powers of Eleking, Neronga, and Eledortoise to create Eleki-Miclas, though he stilled retained his timid personality.

See Ultraseven

Cowardly Lion: Miclas is extremely lacking in confidence and needs encouragement to be able to face enemies. This would later become a major trait of future incarnations of Miclas, including the original Ultraseven one. Teppei justifies this, explaining that the original Miclas was much braver as Ultraseven was a strong and benevolent leader to it.
Invisibility: Thanks to Neronga and Eledortoise.
Shock and Awe: When upgraded to Eleki-Miclas, he gains the ability to channel lightning through his body and shoot it from his horns. Additionally, he's immune to electric attacks.
Spring Jump: Capable of this, but his landing skill is much less impressive.

Lim. Eleking

First Appearance: Terrible Predator

A chibi Eleking that spawned from an error in the Maquette Monster creator when Miclas rejected a miniscule amount of Eleking's data during his upgrade to Eleki-Miclas and the system, unsure of what to do with, spawned an Eleking. Although it unnerved everyone (except Konomi) at first, GUYS decided to let it stay and play the role of mascot. The chibi monster also made a brief return in Ultra Galaxy Mega Monster Battle.

Cuteness Proximity: Konomi's heart melts at the sight of it when it first appears, although the rest of GUYS is freaked out by it. The scene is both hilarious and adorable.
Energy Absorption: Has a habit of eating the electricity around Phoenix Nest.
Fun Size: Comes in this size due to being created from a very tiny amount of Eleking data from the Maquette Monster creator.

Ridiculously Cute Critter: A playful, chibi version of one of the franchise's most popular Kaiju.
Shock and Awe: Like the normal Eleking, it can deliver powerful shocks when disturbed, as George learned the hard way.
Spell My Name With An S: Sometimes called Rimu Eleking.
Super-Deformed: It's a chibi after all.

Windam

Windam / Fire Windam

First Appearance: Mother's Miracle

The second Maquette Monster chosen by GUYS. Windam is less cowardly than Miclas and takes orders better, but is also rather mindless in comparison. Later on, GUYS downloaded the fire powers of Zetton, Pandon, and Black End, allowing GUYS to use the robot as Fire Windam when needed.

See Ultraseven

Playing with Fire: Fire Windam possesses the ability to shoot fireballs from the flamethrower on its left hand.
Right Hand of Doom: As Fire Windam, he possesses a flamethrower in place on his left hand. His head fin is also changed to a red colour.
Spring Jump: Can jump clean over the heads of other kaiju, a trait not seen in Ultraseven.
Took a Level in Badass: In Ultraseven, Windam was basically a 40 meter tall punching bag for the bad guys who could be fooled by simply running around it in circles! In Mebius, Windam is now capable of taking on other kaiju without breaking too much of a sweat, even without its Fire upgrade.

Empera Army

Alien Empera

https://static.tvtropes.org/pmwiki/pub/images/emperor_new.png

First Appearance: Mefilas' Game

Voiced by: Kenji Utsumi

The Lord of Darkness, Empera was defeated thousands of years ago when he conquered the Land of Light only for the Ultras to fight back and defeat the Emperor. However he would return, as made clear in Mebius' battles against the first Imperiser and the 4 Heavenly Kings. Upon arrival, Empera decreed that humanity must submit to him by banishing Mebius, encased the sun in solid darkness, sent out Mass-Produced Imperisers, and personally ravaged Tokyo — putting Mebius, GUYS, and all their allies up against the greatest threat the world had seen.

Achilles' Heel: He has a few wounds of light near his waist left from his battle with the Father of Ultra. By exploiting these wounds, Ultraman Hikari is able to injure him and Mebius in Phoenix Mode is able to destroy him by completely opening them up in the final battle.
Arch-Enemy: Of the Father of Ultra, who fought him one on one in the Land of Light thirty thousand years ago in a duel that ended in a draw. Part of his motive for targeting Earth is to get back at the Ultra Father by destroying a planet he and the other Ultras cherish.
Bad Boss: Executes Alien Mefilas after he failed in killing Mebius.
Badass Cape: It can actually act as a force field.
Big Bad: One of the major antagonists of the Ultra Series, and can be considered the Big Bad of not just Ultraman Mebius, but the classic Showa continuity in general as his actions are directly and indirectly responsible for most, if not all, of the alien and monster attacks on Earth.
Casting a Shadow: Has numerous shadow-themed powers.
Dark Is Evil: Has a dark color scheme and yes, he is evil. His goal is to destroy light and spread darkness throughout the galaxy.
Disappears into Light: His death sees his body erupting from within into light.
Early-Bird Cameo: Is actually first seen in Ultraman Taro in a flashback, and was supposed to be the villain of Alien Temperor's 2-part debut.

Evil Counterpart: To the Ultras in general, as like the Ultras, his race faced the crisis of their sun dying out. Whilst the Ultras built the Plasma Spark as their replacement and used their newfound light-based powers for justice, Empera embraced the darkness and used his newfound powers of darkness to become an evil conqueror.
Evil Overlord: Leads an army of monsters and seeks to conquer the galaxy and enshroud it in darkness.
Face Death with Dignity: Empera accepts his end surprisingly well after he's fatally wounded by Mebius, simply acknowledging that the bonds between the Ultras and their human counterparts are what enabled them to prevail before fading away.
Finishing Move: The Rezolium Ray, his answer to the Ultras' beams and what he uses to kill Ultraman Mebius.
Galactic Conqueror: He has his sights set on purging all light from the galaxy and more. He even managed to conquer and occupy Nebula M78 at one point.
Greater-Scope Villain: Easily the most powerful and influential villain in the Land of Light universe, with only Alien Rayblood possibly exceeding him in terms of power. Many of the conflicts the Ultras have been involved in were affected by him in some way.
- Yapool, the Big Bad of Ultraman Ace, is a follower of his.
- In Ultraman Taro, his invasion of the Land of Light is first brought up, although Empera himself does not make an appearance.
- The immense power he displayed during his invasion of the Land of Light is part of what inspired Ultraman Belial to begin his own quest for power at the expense of the other Ultras, resulting in his eventual Face–Heel Turn into one of the Ultras' worst enemies.
- Two of the Mebius Gaiden specials deal with the after-effects of his legacy. He created the titular villain of Armored Darkness, and Ghost Rebirth involved a plot by his subordinates to resurrect him.
- The villain of Super Galaxy Wars, Ark Bogarl, was a former servant of Empera who was sealed by him for being too rowdy.
Healing Magic Is the Hardest: While immensely powerful, it took him 30,000 years to recover from the war enough to make a second attempt, while the Father of Ultra received an identical wound and didn't take nearly as long. Any attempt to actually revive him is also shown to be far more difficult than is typical in this universe.
The Juggernaut: He was able to block swords with his bare hands and caused explosions all over Tokyo by simply landing in the middle of the city.
Last of His Kind: According to some sources, he was the last of a race of aliens who were killed off when their planet's sun went died. How did he survive? By embracing the power of darkness, of course!
The Man Behind the Man: Implied to have manipulated the events of the series (and to a lesser extent, every monster and alien attack in the previous series, considering the Space-Time Emitter) to ensure his arrival. Further media published by Tsuburaya themselves revealed that the Temperor from Ultraman Taro is merely another henchman of Empera.
Mind over Matter: Has immense psychic power, with his favorite being telekinesis, which he uses to stop even a single hit from landing on him.
Monster Lord: He commands a massive kaiju army, which he used to invade the Land of Light eons ago.
Playing with Fire: Can conjure deep red fireballs as projectiles.
Predecessor Villain: Ultraman Belial would follow in his footsteps in trying to invade the Land of Light with an army of kaiju. The overwhelming power Empera showed off during his fight with Ken and Belial is also part of what inspired Belial to seek out more power in the first place, leading him to attempt to steal the Plasma Spark.
Rank Scales with Asskicking: You don't lead an army of kaiju, robeasts and eldritch abominations without being immensely powerful yourself.
The Royal We: He uses the regal and archaic "yo" pronoun to refer to himself, which subtitles tend to translate as "we" to keep the same effect.
Shadow Archetype: Literally. His people were faced with a similar dying sun crisis as the Ultras, but instead of working with his people to resolve it he embraced the power of darkness instead.
Spell My Name With An S: His name has been translated as both "Alien Empera" and "Alien Emperor", though the former is the spelling most commonly used.
Throat Light: Alongside his glowing eyes, Empera lets out a beam of light from his larynx moments before he dissolves into light particles.
Torso with a View: How he's finally, finally defeated, with Mebius Phoenix Brave, unleashing the Mebium Dynamite empowered by GUYS' amplifier, ultimately ripping Empera through the middle and leaving behind a shining hole. And it took three episodes for that to happen!

Imperiser

https://static.tvtropes.org/pmwiki/pub/images/inpelaizer_render.png

First Appearance: Day of Farewell

Empera's robotic soldiers. One was sent as a scout to devastate GUYS, Mebius, and even a visiting Ultraman Taro, forcing Mebius to gain his Burning Brave Mode. Later, thirteen Mass-Produced Imperisers were placed across the globe by Empera to threaten humanity and fight Mebius. Mebius would later encounter the original one when it was resurrected in the Monster Graveyard, but Mecha-Zam slew it.

The Imperisers have also appeared a few more times in other Ultra Series.

Back from the Dead: The first one returns from the Monster Graveyard in Ghost Rebirth.
Blade Below the Shoulder: If Imperiser's arms get blown off, it simply regenerates them into a sword.
Conservation of Ninjutsu: A single Imperiser? Decimates GUYS and two Ultramen (Including the prodigy Taro who is Mebius' mentor). A whole army of Mass-Produced Imperisers? Each one dies in one hit.
From a Single Cell: Despite being a robot, it can do this due to its highly advanced self-repair system. The only way to destroy one permanently is to destroy that.
Half the Man He Used to Be: Ultraman Taro managed to defeat one by blowing up its upper half from above the waist using the Storium Dynamite, but unfortunately its not enough to stop it from regenerating.
Humongous Mecha: Used by Empera as his army's scouts and cannon fodder.

The Juggernaut: Not even Taro's Ultra Dynamite could kill even one these guys, as when Taro blew the top half off, its legs still survived and teleported away!
Knight of Cerebus: As the monster of the Wham Episode as well as the most powerful Mebius has faced yet, definitely.
Mecha-Mooks: The robotic footsoldiers of Empera's armies.
More Dakka: Their combat tactics are to simply spam lasers and energy orbs from the cannons mounted on their "head" and shoulders.
Spell My Name With An S: Imperiser, Imperializer, Imperizer, Inpelaizer... Nobody's too sure.
Spin Attack: Has a 360-degree waist that allows it to simply spin around while shooting for maximum destruction.
Teleport Spam: Displayed by the Mass-Produced Imperisers, but even the original could teleport to evade GUYS.
This Is a Drill: The Mass-Produced Imperisers created these instead of the standard Blade Below the Shoulder.
The Worf Effect: On Ultraman Taro, who struggles to defeat one as proof of the robots' power.

The Dark Four Heavenly Kings

The Dark Four Heavenly Kings in General

Empera's most powerful and reliable troops, the Dark Four Heavenly Kings ("Ankoku Shiten'no") are a cunning and deadly group that appears in the last arc of the series as the prelude to Empera's return and try to make sure Earth is ready for Empera to take over.

Back from the Dead: In Ghost Reverse they return to life thanks to an anomaly in the Monster Graveyard and plot to resurrect Empera using "Ghost Rebirth/Mechazam", a robotic being that would house Empera's soul, wield the Giga Battle Nizer and have none of Empera's weaknesses.
Co-Dragons: Technically act as equals in their positions as Empera's top underlings, but some like Mefilas and Yapool often tend to stand above due to their intelligence and loyalty.
Dwindling Party: They slowly lose members as Mebius defeats them in their focus episodes, with Mefilas being the only one to avoid that fate... Only to be brutally executed by Empera for his failure.
Elite Four: The four of them are Empera's most powerful, loyal and reliable lackeys.
Legion of Doom: Zig-zagged. One of them is a villain the Ultras have fought before, one of them is a member of a species the Ultras have fought before, but the other two are entirely new.

Yapool

First Appearance: Ultraman Mebius and the Ultra Brothers, The Resurrection of Yapool (in series)

Voiced by: Tesshō Genda

One of Empera's generals, the 4 Heavenly Kings, Yapool attacked Earth with his Choju U-Killersaurus five years after Ultraman 80's departure, but was sealed under the sea off Kobe by Ultraman, Ultraseven, Ultraman Jack, and Ultraman Ace. He and his monster were resurrected by an alliance of evil aliens, and he escaped to his home dimension, where he would later resurrect some older Choju and team up with the rest of the 4 Heavenly Kings. He was the first of them to try and defeat Mebius by using more Choju and trapping the hero in his home dimension, attempting to break the hero's faith in humanity while he lured the rest of GUYS into a trap.

See Ultraman Ace

Demoted to Dragon: This time, he's just one of the Four Heavenly Kings who serve Empera..
Dragon Ascendant: He was apparently Empera's Dragon during the original war with the Ultras, but went on to become a Big Bad himself in Ace (and in The Movie, where he controls U-Killersaurus against Mebius and the Ultra Brothers) until Empera returned.
The Dragon: Of the 4 Heavenly Kings towards Empera, being the emperor's most loyal servant and the most passionate enemy of the Ultramen out of the 4 Heavenly Kings.
Evil Genius: He's still every bit as ingenious and diabolical as he was in Ace.
The Man Behind the Man: He subtly swayed the minds of Aliens Zarab, Guts, Nackle, and Temperor to free him and U-Killersaurus from their underwater prison off Kobe.
Sealed Evil in a Can: In The Movie, due to the Ultra Brothers sealing him under the sea while he was in the body of U-Killersaurus.

Deathrem

Alien Deathre Deathrem

First Appearance: Threat of Mebius Killer

Voiced by: Daisuke Gōri

The second of the 4 Heavenly Kings. Deathrem plotted to destroy the trust that humans had in Ultramen by trapping GUYS in a containment field and telling Earth that GUYS would only be freed if he was allowed to defeat Mebius. He then returned when the 4 Heavenly Kings were resurrected in the Monster Graveyard.

Other members of Deathrem's species have appeared in the Ultra Series since.

A Lizard Named "Liz": Justified as he was the only member of his species known until much later.

Body Horror: His design is meant to look like he's been turned inside-out.
Cyclops: Has a single yellow eye.
Dem Bones: He looks like he’s decorated with bones.
Evil Sounds Deep: Has the deepest voice of the 4 Heavenly Kings, due to being voiced by Daisuke Gōri.
Manipulative Bastard: His eponymous plan was to imprison GUYS in a containment field and decree that he must destroy Ultraman Mebius if GUYS is to be freed, leaving Mirai in a crisis about whether it was more important to save his friends or the civilian populace, who were angry at the indecisiveness of GUYS.
Names to Run Away from Really Fast: Deathrem.
Playing with Fire: The Deathrem Inferno, which is his ability to open portals that shoot out homing fireballs at targets.
Right Hand of Doom: His left hand is equipped with massive claws.
Spell My Name With An S: Also known as Desrem.

Grozam

Alien Groza Grozam

First Appearance: Threat of Mebius Killer

Voiced by: Hisao Egawa

The third Heavenly King, Grozam's plan was to simply challenge Mebius in battle. He easily defeated the hero with his freezing breath, leaving GUYS to figure out how to get past his unmeltable ice and nigh-immortal form. Grozam later returned when the 4 Heavenly Kings were reborn in the Monster Graveyard.

Other members of Grozam's species have appeared in the other entries of the Ultra Series.

A Lizard Named "Liz": Justified as his species wasn't established until much later.
An Ice Person: Not only is he able to breath blasts of freezing air, but he's also completely made out of ice.

Breath Weapon: Breathes an icy mist so powerful that it could freeze fire.
The Brute: Of the 4 Heavenly Kings, as his evil plan is simply to pummel Mebius and let humanity despair at the defeat of their hero, without considering that GUYS would try to do something about it.
Cyclops: A single blue eye.
From a Single Cell: Being blown to bits doesn't stop him from regenerating either.
Half the Man He Used to Be: Was sliced diagonally into two with Ultraseven's Eye Slugger. It doesn't work because...
Healing Factor: He even regenerated from being sliced in two by Ultraseven!
Horned Humanoid: Two downward-curving horns on his head.
In the Hood: In his human form, he appears as a hooded figure before revealing his face.
Logical Weakness: As an alien made of ice he is naturally vulnerable to fire and heat. The problem is that he's so big that the heroes cannot produce enough heat to keep him down. GUYS gets around this by letting Ultraman Mebius and Ultraseven blow him to pieces, then hitting him with superheated air while he attempts to pull himself together.
Losing Your Head: His entire body gets blown into bits by Ultraseven and Mebius, save for his head... who then speak up and tuant the Ultras.
"Didn't I already tell you? I'm the Immortal Glozam!"
Mythology Gag: His imprisonment of Mebius is an intentional parallel to Ultraseven's crucifixion at the hands of Alien Guts.
Pinned to the Wall: Not him, but Glozam does this to Ultraman Mebius, pinning the Ultra into a dam.
Rasputinian Death: Blown into bits, and then each and every bit of himself gets incinerated by the GUYS Phoenix's Maxwell Tornado. And he's still very much alive and conscious during the incineration.
Spell My Name With An S: Also called Glozam due to "L-R" confusion in the Japanese language.
Weaksauce Weakness: Defeated by using superheated air to completely melt him into nothingness.

Alien Mefilas

First Appearance: Threat of Mebius Killer

Voiced by: Seizō Katō

The last of the 4 Heavenly Kings, Alien Mefilas planned to defeat Mebius in the most humiliating way possible — altering the minds of everyone on Earth so they would view Mefilas as a hero and Mebius as a villain, turning even Mirai's friends against him. Mefilas would later return when the 4 Heavenly Kings were resurrected, though inexplicably as Armoured Mefilas.

See Ultraman TV Series

Art Evolution: His eyes are much wider compared to the original Mefilas.
Back from the Dead: In Ghost Rebirth, albeit now wearing a suit of armour.
Engineered Heroics: In order to prove himself as a hero, Mefilas unleashed the kaiju Gromite into the city and defeats it in public to further sell the illusion of him being the hero.
The Evil Genius: Of the 4 Heavenly Kings towards Empera, for he's the most intelligent of the group and uses advanced technology to brainwash the world into seeing Mebius as an evil alien and him as the protector of Earth.
Face Death with Dignity: Right as Empera is executing him, Mefilas simply apologizes for failing his master and laments briefly that his role in Empera's goals was soiled by his failure before being blown up.
Genre Savvy:
- When Grozam gloats about GUYS being helpless to rescue Mebius and defeat him, Mefilas is quick to point out that he should not be underestimating the humans as they have saved the Ultras and defeated monsters by themselves many times before. He was correct as Grozam's defeat comes thanks to GUYS ensuring he can't regenerate himself after being blown to bits by melting his remains.
- Mefilas also wasn't kidding when he said he would kill Mirai in a manner that would leave him in utter despair. In a series themed around friendship, there's truly no worse way for a villain to kill the hero than by turning friends against them. Of course, Mefilas is eventually foiled by his underestimation of the strength of GUYS' bonds.
Identical Stranger: Despite his similar suit design and sharing a voice actor in addition to his familiarity with the original Ultraman, he is not the first Alien Mefilas that Hayata/Ultraman fought in 1967, who exited and sworn to fight Ultraman in the future. In a Bandai-authorized official blog, he is given the designation Alien Mefilas III.
Know When to Fold 'Em: When cornered by GUYS, Mebius and the original Ultraman then told that he broke his own terms about not harming humans, Mefilas concedes and leaves without further trouble while swearing to return. Too bad for him that his boss won't let such failure go unpunished.
Mind over Matter: In this series, Mefilas has telekinetic abilities, which he uses to redirect beam attacks or guide his own energy attacks.
Mythology Gag:
- His We Will Meet Again statement to Mebius and Ultraman, as well as his admittance to defeat, are what the original Mefilas told Ultraman. They even vanish in the same manner.
- Additionally, a brief bit of Mefilas firing one of his Hand Blasts at Ultraman's chest to no avail is a near-perfect shot of when the monster Neronga did something similar to Ultraman as well.
You Have Failed Me: His fate, as Empera mercilessly blow him up with his Rezolium Ray upon leaving Earth as punishment for failing.

Bogarls

Bogal / Bogalmons

https://static.tvtropes.org/pmwiki/pub/images/bogal_new_6.png

Click ^here for Bogalmons

Click ^here for her human form

First Appearance: Two From the Deep Sea

Voiced by: Moeko Koyama (also human form actor)

A terrible creature that has devoured life on countless worlds, Bogal came to Earth from the planet Aarb in the form of a lady in white to call forth monsters that were dealt with by GUYS. Her presence remained unknown to the team until Tsurugi's arrival forced her to change tactics, and she began to consume the monsters she summoned in order to transform into a more horrid and powerful form called Bogalmons.

Achilles' Heel: Electricity. Unfortunately for GUYS, she loses this when she becomes Bogalmons.
Action Bomb: When Tsurugi arrives on Earth, Bogal starts consuming monsters to build enormous amounts of energy into her body and become one as Bogalmons.
Animal Motifs: Snakes. Her back mouth is meant to resemble a cobra's hood while her methods of consumption are similar to those of any snake. The way she leaves behind a decoy to escape in Episode 8 also resembles a snake shedding its skin.
Archenemy: To Hunter Knight Tsurugi, who protected Aarb one of the planets whose inhabitants she devoured.
Arc Villain: Of the first 10 episodes.
Big Eater: For Bogal, the kaiju are just appetizers. The main dish is the rest of Earth.
The Dreaded: Other kaiju are terrified of her, even when they see her human form
Early-Bird Cameo: Until Episode 6, she appears throughout the series in a human disguise.
Expy: Her design is actually based off some scrapped concept art for Orga from Godzilla 2000.
Food Chain of Evil: An intelligent kaiju that lives to consume other kaiju. There's a reason why Kelbeam fled in terror upon spotting her human form.
Hand Blast: Can shoot purple orbs of energy from her hands.
The Heavy: Although only appearing in the first 10 episodes, her presence is what kickstarts the plot.
Mind over Matter: Has shown telekinesis in both monster and human form.
More Teeth than the Osmond Family: Her mouth, which is disguised as her back!
Monster Mouth: The membranes connecting her arms to her torso can expand to form a vertical mouth filled with teeth. As Bogalmons, she has a pair of wing-like jaws on her back instead.
Not Quite Dead: In Episode 8, Tsurugi and Mebius seemingly kill her, but then it turns out she simply fled with an illusion in her place.
Omnicidal Maniac: For Bogal, the universe is nothing more than her personal buffet.

Overly-Long Tongue: In her human form. She tends to lick her lips with it hungrily whenever the Monster of the Week appears.
Prehensile Tail: She uses it to to grab objects, including trying to snatch the C-PIN 929 (although Mebius was able to slice it off as a result) and even subduing Twin Tail to tak on Gudon when she interrupted their battle to eat them.
Shock and Awe: As Bogalmons, she can shoot beams of lightning from her back.
Snakes Are Sinister: Snakes are a large part of her design.
Spell My Name With An S: Bogal or Bogar?

Swallowed Whole: Her favoured form of finishing off other monsters.
Taking You with Me: What she intended to do with Tsurugi and Japan as Bogalmons. See Action Bomb above.

Voluntary Shapeshifting: Can turn into a human woman to go around unseen. Monsters will still recognize her presence though.

Lesser Bogals

https://static.tvtropes.org/pmwiki/pub/images/bogal_jr_new.png

First Appearance: A Call from Space

Bogal's human-sized children that continued to call monsters to Earth. Two opened up a gateway to the Monster Graveyard and encountered GUYS there when a distress call from the ship Arandas trapped in the Monster Graveyard came to the team's attention. Three more later appeared on Earth, where they attacked Mirai and attempted to pull Ryu into the Monster Graveyard.

Eye Beams: They shoot purple orbs of energy from their eyes.
Food Chain of Evil: Like their mother, they consume other monsters. However, since their too small to attack kaiju, they usually just scavenge from the corpses floating around the Monster Graveyard.
Hand Blast: They can spam dark blue bolts of energy from their claws.
Make My Monster Grow: They turn kaiju-sized through Monstrous Cannibalism, changing appearance if they eat at least two of their fallen kin.
Monstrous Cannibalism: They consume their own dead to grow in power and size much like how Bogal became Bogalmons.
More Teeth than the Osmond Family: The final Lesser Bogal.
One-Winged Angel: The last Lesser Bogal consumes its fallen comrades to gain a horrid visage reminiscent of a Venus Flytrap.
Overly-Long Tongue: The last one of them uses this to snag Ryu's plane and try pull him into a portal to the Monster Graveyard.
Villainous Glutton: As ravenous as Bogal, but far more feral.

Other Antagonists

Zamsher

https://static.tvtropes.org/pmwiki/pub/images/zamusha_new.png

First Appearance: The Swordsman from Space

Voiced by: Isamu Sugaya

The greatest swordsman in the universe, Zamsher had battled Hunter Knight Tsurugi many years ago and lost. He hitched a ride on the Oshima Comet, which was making a collision course with Earth, in order to avenge this defeat and once again prove himself to be the mightiest warrior in the cosmos — unaware that Tsurugi had given up his bloodthirsty ways to become a heroic protector.

Anti-Hero: Fills in the role left vacant by Tsurugi's redemption into Ultraman Hikari.
Arch-Enemy: Considers Tsurugi to be his. Though later on, it becomes more of a Worthy Opponent rivalry.
Badass Normal: Despite having no powers, he was able to fight against the Ultramen and survive as well as take on some of the most powerful characters evenly.
Back for the Finale: Where he battles Empera alongside Hikari.
Bilingual Bonus: His name literally means "The Warrior" in Japanese.
Blood Knight: He fights for the sheer sake of it.
Curb-Stomp Battle: Against almost anyone who battles him as Alien Valky and the two Alien Magmas found out.

Glory Seeker: He fights in order to prove himself as the most powerful warrior in the universe. However, he later realizes the true meaning of fighting is about protecting others.
Heroic Sacrifice: In the final battle against Empera, he saves GUYS from a potentially fatal attack.
Katanas Are Just Better: His Hoshikirimaru is capable of slicing the Mebium Blade in two, chopping up giant robots, and even slicing a comet into hundreds of shards of rock and ice.
Master Swordsman: He fancies himself the greatest swordsman in all of space, and has certainly lived up to it, having fought toe on toe with the likes of Hunter Knight Tsurugi and (according to Expanded Universe material) Emperor Galtan, Alien Tsuruk, and Alien Terrorist.
Named Weapons: His sword is called Hoshikirimaru, meaning "Star Slash Circle".
Noodle Incident: Exactly what went down in the battle between Zamsher and Tsurugi is never explained.
The Only One Allowed to Defeat You: His reason for coming to Earth is this to Tsurugi.
Red Eyes, Take Warning: Technically "red eye", but still.
Samurai: A space samurai with all the traits of one.
The Worf Effect: Defeats three aliens all in short order without breaking a sweat and kills several Imperisers too. Becomes a victim of this when he battles Empera.
Spell My Name With An S: Zamusha, Zamsher, Zamsha, Zamshar, etc. Lately Tsuburaya has officially settled on Zamsher being the official translation in English

Mitsuhiko Hirukawa

And the Most Punchable Face Award of 2006 goes to...

Played by: Kato Kosei

An unscrupulous journalist notorious for his tabloid style of writing and penchant for digging up or creating dirt around celebrities. Hirukawa particularly likes trying to ruin GUYS' reputation, having no respect for the team and their work.

Chekhov's Gunman: Originally appeared in Episode 28 "Konomi's Treasure" working with a childhood friend of Konomi to make a scandal around GUYS. Nobody ever expected his reappearance alongside that of Yapool and Aya Jinguji, or that he would reveal Mirai's secret identity to the rest of the world.
Hate Sink: In a show filled with giant kaiju and alien invaders, this miserable excuse of a human being somehow sticks out as being the most unscrupulous and despicable character. Sadly he didn't really get any sort of comeuppance by the series' end.
Humans Are the Real Monsters: Perhaps he's the only human in the series to be an unrepentant scumbag whereas the rest of the villains are invaders from outer space. So much so that Yapool is even amused by Hirukawa's repulsive behavior towards Mirai and takes advantage of the trope through Break Them by Talking into crushing the young Ultra's faith in humanity. Revealing Mirai's identity as Mebius to the public was simply nothing more but a middle finger to both Mirai and crew GUYS.
Immoral Journalist: Very much so. He will do anything to get a good story for the tabloids, regardless of what kind of horrible things it requires (or even if the story is even remotely true).
Jerkass: You might notice he's the only human character in the antagonists folder. That would be because he is quite easily the most despicable human character in the show, having zero redeeming qualities or any sense of morality.
Karma Houdini: Despite all the horrible things he does, including ousting Mirai as Mebius, he ultimately gets no serious comeuppance.
More Hateable Minor Villain: Mitsuhiko Hirukawa, while far away from being much of a threat compared to other villains in the show, is nonetheless the absolute least sympathetic character in it and lacks any redeeming factor to his character. The guy is simply a greedy journalist who doesn't cares who he hurts in his pursuit of good news, trying to discredit GUYS purely because it'll make him famous and even unwittingly helps Yapool by revealing Mirai's identity as Ultraman Mebius to the world.
Paparazzi: Though he's not a photographer, he certainly fits the mode, as he specializes in creating slanderous stories using superficial evidence.

Regular Monsters and Aliens

Dinozaur

https://static.tvtropes.org/pmwiki/pub/images/dinozuar.png

First Appearance: A Fateful Encounter

The first monster to appear on Earth since Margodon was defeated 25 years ago, the extraterrestrial, razor-tongued Dinozaur is Ultraman Mebius and GUYS' first opponent summoned to Earth by Bogal. Several more appear in the early part of the series, but are dispatched by the heroes before they cause any trouble.

Bilingual Bonus: Dinozaur's name is the Polish word for "dinosaur".
Bizarre Alien Biology: It uses its razor tongue to snatch particles floating about in the depths of space. Weirder still, blowing off its head will result in a Dinozaur Reverse!
Early-Bird Cameo: A small clay model of Dinozaur appears in Episode 22 of Ultraman Max. See here.
Expy: Its design is based on Sandros, Big Bad of Ultraman Cosmos 2: The Blue Planet, as well as early concept art for Orga from Godzilla 2000.
Multiple-Tailed Beast: Two tails. They carry large nerve clusters within them, so they effectively act like secondary brains.
Overly-Long Tongue: Extremely thin and razor sharp. Capable of slicing a skyscraper in half.
Shoulder Cannon: Fires hailstorms of laser bolts from its shoulders.
Starter Villain: For Ultraman Mebius, serving as an excellent demonstration of his inexperience.
Starter Villain Stays: Much later on the Dinozaur return as an entire herd.
The Worf Effect: Used with GUYS. A single one totally decimates the original GUYS in Episode 1, but in Episode 11, GUYS destroy an entire herd of the monsters and manages to blow the survivor's head off.
Your Head Asplode: The surviving Dinozaur in Episode 11 is defeated this way, allowing it to become Dinozaur Reverse.

Gudon

First Appearance: Our Wings

The second monster summoned by Bogal, appearing at the outskirts of Tokyo while GUYS still needed new recruits after their disastrous first fight with Dinozaur. A second individual later appeared fighting Twin Tail, but had its battle interrupted when Bogal came to eat the two.

See Return of Ultraman

Curbstomp Battle: On the receiving end twice. First by Bogal in Episode 9, and then by Zetton in Episode 27.
Mons: In Episode 27, Teppei uses a Maquette version of Gudon as a test monster against the Maquette Zetton.
Mythology Gag: Seen battling Twin Tail again in its reappearance.
- Also the first one emerges near a construction site at sundown, mirroring what happened in the original Gudon's battles with Ultraman Jack.
Starter Villain: GUYS' very first enemy after the original team (except Ryu, of course) was all killed by Dinozaur.

Birdon

First Appearance: Only One Life

The third monster summoned by Bogal, appearing out of Mt. Okutama where it was able to incapacitate Mebius with its powerful poisons and leave GUYS fretting about how to defeat a monster infamous for killing two Ultra heroes in the past.

See Ultraman Taro

Achilles' Heel: As dangerous as it is, if a vein in its poison sacks is damaged, the poison floods its system and leaves it vulnerable.
Continuity Nod: It reappears where the original in Ultraman Taro did, at Mt. Okutama. A few have theorized that it's supposed to be the original Birdon too, since Taro only managed to seal the monster back inside the volcano at the end of the three-parter.
The Dreaded: Managing to kill two Ultras in the past tends to make you this. Everyone has an Oh, Crap! when it shows up, because the past event is still remembered. It manages to give Mebius a Curbstomp Battle in their first fight and injures him so badly he's still weakened in their rematch.
Karma Houdini Warranty: In a meta sense, Birdon in Ultraman Taro was simply sealed away instead of killed due to its sheer power, this one has no such luck and is promptly destroyed by GUYS' and Mebius' efforts.
Hoist by His Own Petard: Its defeat comes from having the sacks holding the venom damaged in such a way that it's flooded with its own venom.
Poisonous Person: Whereas the original Birdon simply had a very sharp beak, this incarnation (and all subsequent ones) has a venomous beak.

Kelbeam

https://static.tvtropes.org/pmwiki/pub/images/cherubim.png

First Appearance: Broken Bonds

A vicious alien monster called to Earth by Bogal while GUYS was testing their new Maquette Monster Miclas, who although too cowardly to face Kelbeam was also their only hope against its arsenal of weapons. A second one later appeared working in unison with an Earthtron it mind controlled by manipulating GUYS' new monster-commanding radiowaves, and a third one then appeared when Armoured Darkness made a beeline for Earth, but was dispatched by Miclas.

Kelbeam proved to be a fairly popular kaiju and has since made appearances in other Ultra Series.

Aim for the Horn: GUYS managed to give Mebius a hand by firing a concentrated energy blast from their weapons into the first Kelbeam's horn, destroying it entirely.
Beware My Stinger Tail: A spiked club perfect for bashing Ultramen or other monsters.
Breath Weapon: A rapid stream of fireballs.
Expressive Ears: Has two ears that flash up whenever he breathes his fireballs. They also catch radio waves to manipulate them.
Female Monster Surprise: The first Kelbeam was actually a female that laid an egg while hiding in the sea which hatched into the second Kelbeam.
Half the Man He Used to Be: The first one's fate.
Horn Attack: In point-blank combat, Kelbeam can use its horn to smack enemies.
Jerkass: Unlike most Kaiju, Kelbeam seems to rampage simply because he feels like it. Best shown in Episode 20 when he mind controls Earthtron and proceeds to bully the lesser monster into fighting Mebius for him. When he loses control over Earthtron, prompting the former servant to leave peacefully, he steps on Earthtron's tail and makes it run back into the fight.
Kick the Dog: A lot.
- Brutally beats up the timid Miclas.
- Mind controls and bullies Earthtron. He even gets Earthron killed by forcefully dragging it back into the fight by stepping on is tail, after its freed from Kelbeam's mind control and tries to leave.
- Taken almost literally when he nearly kills Takato's dog in a flashback in Ultraman Mebius & the Ultra Brothers, destroying the boy's self-confidence and his faith in Ultraman.
Screw This, I'm Out of Here!: Why the first one leaves during the first fight with Mebius. When Kelbeam catches sight of Bogal in her human form, it is scared to death and runs away in terror.
Spell My Name With An S: Also spelled as Kelbim or Cherubim.
Spin Attack: Kelbeam can levitate himself and spin rapidly like a tornado, smashing everything in its vicinity with its tail.
Villain Team-Up: With Earthtron in Episode 20, though only because it forcefully mind-controlled Earthron with GUYS' newest invention to do so.
Wolverine Claws: Long nasty claws for slashing his enemies.

Sadorah

First Appearance: Reverse Shot

Several of these monsters were summoned by Bogal to be consumed by after she learned Hunter Knight Tsurugi was coming to Earth. They hid in the Japanese mountains striking at victims with their extending claws from the mists they created.

See Return of Ultraman

Butt-Monkey: Nothing ever goes right for them, they solely exist to be killed by either Ultras, humans or stronger monsters. Many of them even appear in cameos to be eaten by Bogar offscreen.
Dirty Coward: They rely on creating fog to cloak themselves while striking from behind with their pincers. Even during the battle with Mebius, the Sadorahs are content to let one of their kind fight Mebius until he is killed, which is when the rest strike.
Extendable Arms: A trait of Sadorah new to this series that ended up becoming one of its primary abilities in all subsequent appearances.
Mythology Gag: The fog-making powers for Sadorah are derived from the excessive amounts of mist in the mountains where the original lived.
Ominous Fog: From this series onwards, Sadorah has the ability to create these.
Zerg Rush: A new trait in Sadorah that would become one of its defining traits in Ultra Galaxy Mega Monster Battle.

Twin Tail

First Appearance: Two From the Deep Sea

The final monster to be awoken by Bogal, this time at the bottom of the ocean in a massive egg she was incubating in order to lure GUYS to the bottom of the sea and be destroyed. A second one later appeared alongside a second Gudon it was battling, only to be devoured by Bogal when she showed up.

See Return of Ultraman

Art Evolution: Twin Tail's glowing spots are changed from green to blue in this series onwards.
Home Field Advantage: Twin Tail is not an extremely powerful kaiju on land, but when Mebius fights it underwater, he's quickly overwhelmed by the monster's increased agility and speed in its natural environment.
Mythology Gag: Seen battling Gudon again when they two return in Episode 9.
Sea Monster: Revealed to be one in this series. Also displays a change in body shape, switching from the iconic "upside-down" position to a flattened form like a horseshoe crab in order to swim.

Alien Fanton

First Appearance: Fanton's Lost Item

Voiced by: Yasuhiko Kawazu

A race of gluttonous but friendly aliens who solved their homeworld's food shortage problems with the marvelous C-PIN 929, a ball-sized foodstuff that could grow based on the amount of oxygen on a planet. However, Bogal attacked the ship delivering it to consume the C-PIN 929 for herself. The item fell on Earth in its capsule, so one Fantonian requested GUYS to assist him in finding it before Bogal could.

Fantonians have made a few more appearances in the Ultra Series since, with the most prominent being Dr. Guruman from Ultraman X, the chief scientist of the series' defense team Xio and one of the show's main characters.

Aliens Speaking English: Averted with this particular representative, who is one of the few alien characters in the franchise to speak in their native language. Later members of the species are able to speak Japanese, however.
Amusing Alien: The Fanton sent to speak to GUYS. He speaks a language similar to inebriated speech, drives Toriyama and Maru nuts with his constant demands for food and performs a bizarre dance before digging in.
Animal Motifs: Snails as seen in their eyestalks and the spiraled shoulders.
Back for the Finale: Though unlike Kako and Zamsher, he doesn't help to battle Empera.
Big Eater: The Fanton representative eats an entire month's worth of food in a single sitting, and according to Dr. Gourman, his species eats 13 meals a day!
Bilingual Dialogue: The Fantonian representative speaks in his mother tongue, which, hilariously enough, is reminiscent of a drunken person slurring their speech. Teppei can communicate somewhat fluently with him.
Exposed Extraterrestrials: They don't wear any type of clothing whatsoever.
Expy: He's based on Kanegon, and also bears a slight resemblance to Jar-Jar Binks.
Foreign Queasine: The C-PIN 929, a ball of flesh usually stored in a compressed state, but can expand into a grotesque kaiju-sized pile of flesh. Marina even notes it looks unappetising upon first seeing it.
Mythology Gag: The language the Fanton representative speaks is the same Space Language Ide used to attempt to communicate with the Baltans in Ultraman, with the phrase "Kiete Koshi Kirekirete" which means "you and I are friends" being quoted at the end of "Fanton's Lost Item".
Obsessed with Food: Their culture takes mealtime very seriously, with the Fanton we see performing elaborate ceremonies and ritual dances upon receiving his meal from GUYS.
Planet of Hats: All Fantonians are usually good-natured big-eaters.
Punny Name: Befitting for a species of alien whose culture revolves almost entirely around eating, their name is derived from the Chinese insult "Fan Tong", which is used for people who only think about food.

Dinozaur Reverse

https://static.tvtropes.org/pmwiki/pub/images/dinozuar_reverse.png

First Appearance: Mother's Miracle

When Ryu blew the head off the second Dinozaur encountered by GUYS, the corpse underwent a bizarre transformation and became a more powerful, two-headed form dubbed Dinozaur Reverse — requiring GUYS to get a new Maquette Monster in the form of Windam and Mebius to get help from a reformed Hunter Knight Tsurugi, or Ultraman Hikari.

Backpack Cannon: An evolution of the normal Dinozaur's Shoulder Cannons, allowing Dinozaur Reverse to spam laser bullets against those who attack it from behind.
Discard and Draw: It loses the normal Dinozaur's flight abilities in exchange for gaining a second head with its own razor tongue, allowing its slicing attacks to be even more devastating and unpredictable.
Metamorphosis Monster: Begins as a normal Dinozaur, but thanks to the large nerve clusters in its tail, it can becomes Dinozaur Reverse to compensate for the loss of its head.
Multiple Head Case: Two heads grown from Dinozaur's two tails.
Overly-Long Tongue: Extremely thin, razor sharp, and capable of slicing a skyscraper in half — at a two-for-one price!

Kodaigon The Other

First Appearance: The First Errand

Voiced by: Keiichi Nanba

A statue of the god Ebisu carrying a fish that was brought to life by a canister of Grotescell lost by Adjutant Toriyama when he was assigned to get rid of the stuff after some failed experiments by GUYS to use the alien substance for good.

Achilles' Heel: The statuette had a crack in its legs that allowed Mebius and Hikari to destroy the Grotescell within by firing their beams into it.
Adaptational Comic Relief: Compared to the original Kodaigon? The Other is far more comical and a whole lot sillier, with his fight against Ultraman Mebius and Hikari containing plenty of slapstick and not really played seriously. He also gets an adorable fish statue-minion who speaks in a high-pitched voice.
Beware the Silly Ones: A giant giggling statue of a little old fisherman that proved to be a surprisingly formidable opponent and required Mebius and Hikari to team up to even stand a chance against it.
Breath Weapon: The fish breathes fire.
Continuity Nod: To the original Kodaigon from Return of Ultraman, right down to being brought to life by the same substance used by Alien Grotes.
Flash Step: This version of Kodaigon can side-step from one area to another, an attack Mebius struggles to keep up with.
Flying Seafood Special: The fish is also able to fly.
Golem: Essentially.
The Juggernaut: The crack in its legs was the only part of its body that GUYS and the Ultras' attacks could show some affect on.
Improbable Weapon User: Being a statuette of the Japanese patron of fishermen, it uses a fishing rod in combat.
Lightning Bruiser: Despite its jolly, rotund appearance, it's astonishingly fast, hits hard and can take a lot of punishment, managing to put Mebius and Hikari on the ropes until its weakness was discovered.
Madness Mantra: The fish constantly shouts "Wealth and Good Fortune!"
Suddenly Voiced: The original Kodaigon doesn't have speech abilities, but this one does. As it turns out, it's because the director really liked Keiichi Nanba's voice and gave him an extra role in voicing the statue.

Mukadender

First Appearance: Marina of the Wind

A monster that made itself at home in the Japanese wilds, eating any creature that entered its territory — and it happened to be that Marina and some friends were meeting together in the forest where it lived. Another Mukadender appeared when Armoured Darkness came to Earth, but GUYS quickly destroyed it.

See Ultraman Taro

Not Quite Dead: Mebius blows up Mukadender with a well-placed Mebium Beam, only for the separated head to lunge out of the smoke while his back is turned. Fortunately, Hikari shows up to destroy it at the last minute.
Super-Persistent Predator: Mukadender nearly spends the entire episode chasing after Marina and her friends, even waiting for them to come back out when they hide inside a cave.

Insectas

The male Insectas

First Appearance: One Path

Two insect-like monsters, with the male being the female's spawn. GUYS easily destroyed the female shortly after encountering it, but the male larva managed to crawl into Toriyama's ears where it drove him mad until it switched hosts to Teppei's mother and accompanied her to her husband's hospital, where it quickly completed its growth and battled Ultraman Mebius.

Achilles' Heel: The monsters' weak points are their mouths, which shooting at also helps to disable their ability to command lesser insects.
Big Creepy-Crawlies: Gigantic beetles with the features of the stag and rhino beetle.
Female Monster Surprise: For GUYS when they find out why Toriyama had gone nuts. The baby Insectas is an unpleasant surprise after they learn the gender of the Insectas they had first encountered.
Gigantic Adults, Tiny Babies: The larva was small enough to fit inside a human ear and the adult male it grows into is 45 meters tall. The growth happens within a matter of hours too once the larva had enough of living in a human ear.
Pest Controller: Both sexes can summon swarms of insects to harass their enemies by calling at a certain frequency.
Shock and Awe: Both sexes can shoot lightning bolts from their horns.
Spell My Name With An S: Insectas or Insectus?
Tough Beetles: While starting out as microscopic organisms, adult Insectas grow to kaiju sizes, and the adult male is strong enough to contend with Ultraman Mebius thanks to its strength and ability to command Earth insects to do its bidding, requiring a group effort to be defeated.

Gromite

First Appearance: Phoenix Stronghold

A meteor-like monster from outer space that consumes rock to regenerate itself, requiring GUYS to find a way to penetrate its stony skin with their aircraft. Gromite later returned when Alien Mefilas modified everyone's memories to make them believe that he was the protector of Earth. He summoned a Gromite and assisted GUYS, destroying the monster. Gromite also appeared in Ultra Galaxy Mega Monster Battle.

Achilles' Heel: There's a tiny opening in its neck that reveals the fleshy insides. Harming this area will cause Gromite great pain, but the monster only exposes it when it lowers it head down to feed.
Breath Weapon: Dark red fireballs.
Eat Dirt, Cheap: Rock, dirt, rubble, anything like that.
Healing Factor: Consuming rock gives it this ability, allowing it to strengthen its armour and heal injuries.
Mythology Gag: His design is based on a scrapped Ultraman Nexus monster, yet he was also made using the suit of the Nexus monster Golgolem (with the modified head of Ultraman Max's Grangon).
Rock Monster: Weird example. It's more akin to a mass of internal organs that can gather mineral matter to give itself the rocky body it needs to survive.
Throat Light: When it consumes rock, a light glows in its throat, allowing it to levitate rock into its mouth.

Alien Magma

First Appearance: The Swordsman from Space

Voiced by: Tetsu Inada (both)

A pair of Magma brothers headed for Earth by riding on the Oshima Comet. The duo hoped to take advantage of the resulting chaos from the collision with Earth and conquer it. They did not expect Zamsher to be on the same comet though and decided to kill him. It was something they never lived to regret as both aliens were sliced in two with the comet by Zamsher's sword.

See Ultraman Leo

Art Evolution: Whereas the first brother closely resembles the original Magma, with red hair and blue eyes, the second possesses white hair and red eyes.
Avenging the Villain: They intended to complete the original Magma's conquest of Earth.
Bullying a Dragon: Considering the fate of almost any warrior who tries to duel Zamsher, the two Magmas really should not have made their unprovoked attack on him.
Half the Man He Used to Be: The fate of the second Magma (which also causes the Oshima Comet to split in two).
Long-Lost Relative: The Magmas claim to be related to the one from Ultraman Leo.

Alien Valky

First Appearance: The Swordsman from Space

Voiced by: Makoto Kamiya

Watching Zamsher battle the two Magmas on the Oshima Comet in secrecy, Alien Valky wished to become known as the greatest warrior in the universe by defeating Zamsher. When the comet and the Magmas were destroyed, Valky stepped out to challenge the samurai. Fighting near GUYS' headquarters, Phoenix Nest, Valky soon met his end at the end of Zamsher's sword like all before him.

See Ultraman Taro

Bullying a Dragon: Not as badly as the two Magmas as he does put up a bit of a fight and far longer than the two, but Valky could have picked a more reasonably defeatable opponent than Zamsher.
Curb Stomp Cushion: He actually lasts a reasonable amount of time against Zamsher in the beginning of their fight, but ultimately loses quickly once Zamsher gets more serious.
Pinned to the Wall: Or to the ground. His death at the hands of Zamsher.

Salamandoras

First Appearance: Formation of Our Vows

Appearing suddenly from space, GUYS was more troubled with Salamandoras than UGM was due to its potent regeneration powers. Another one appeared as part of the prelude to Armoured Darkness' arrival to Earth, but GUYS destroyed it easily.

See Ultraman 80

Achilles' Heel: Has a regeneration organ in its throat that it hurt, will prevent the monster from reforming. In its original appearance, this was merely just a very sensitive body part with no other significance.
Continuity Nod: GUYS applies the same tactics UGM used to destroy the original.
From a Single Cell: In its original appearance, it had to be resurrected by the Alien Gorgon. Here, Salamandoras is capable of regenerating by itself.

Bemstar

First Appearance: Pressure on Ultraman

Two Bemstars appear in this series, both following the trail of the Oshima Comet. One was encountered by Ultraman Hikari and defeated by him, while Zoffy convinced him to spare the other Bemstar as a test for Mebius. Sure enough, the monster would trouble Mebius greatly, as he felt very vulnerable against the infamous monster. Fortunately, he would also earn Brave Mode in the battle against it.

See Return of Ultraman

The Dreaded: Mirai was pretty worried about having to face this guy, as he had heard about how the original monster was so tough that Ultraseven had to show up and help Jack defeat it — and Hikari has just left Earth.
Evil Laugh: Makes the kaiju version of one when it attempts to eat Marina in her plane, Mebius' arm, and Hikari's fist.
Mythology Gag: A lot of elements of Bemstar's appearance in the episode are borrowed from its debut episode in Return of Ultraman, "Ultraseven Arrives". Coincidentally, they're both the 18th episodes of their respective series.
Playing with Fire: In this series, Bemstar is able to create a pulse of extreme heat from its Belly Mouth in order to vaporize anything that clogs it.
There Is Another: The Bemstar that Mebius fights is actually one that Hikari and Zoffy had sighted in space after Hikari succeeded in defeating another one.

Daigarugu

First Appearance: The Lonely Grandstander

A beetle-like monster from the depths of space. Daigarugu posses the ability to split itself into three perfect copies that could not be harmed unless all three of them were somehow hit at the same time with one attack.

Aim for the Horn: Have it's horn broken courtesy of the Mebium Blade reflecting its blast.
Big Creepy-Crawlies: Resembles a giant bipedal rhinoceros beetle.
Breath Weapon: Energy bombs.
Came from the Sky: Daigarugu first appears as orb of energy hurtling through space before it crashes on Earth.
Doppelgänger Attack: Daigarugu creates two perfect copies of itself, splitting into three identical monsters with a third of the power of the full creature. This also means the only way to harm Daigarugu is to somehow hit all three monsters at once with a single attack.
Expy: Its ability to split into three projections that require a special technique to defeat makes it one to Mezard, another monster that exists in an incorporeal form and cannot be beaten unless made corporeal.
Horn Attack: Can shoot energy bolts from its horn.
Shell Game: Only one of the three Daigarugus is real, while the other two are projections, but Daigarugu can rapidly switch its real body between them. The real Daigarugu is the one with its horn lit up, which only George was able to see.
Tough Beetles: It's a rhinoceros beetle-esque monster that is very powerful, and can split into three monsters that cannot be harmed unless one hits all three of them at once with a single attack.

Earthtron

First Appearance: The Chief Inspector's Message

A monster that unexpectedly appeared while GUYS was testing a new device that allowed them to command monsters with radio waves. The creature had been mind controlled by the second Kelbeam, who was manipulating the device's radio waves to boss Earthtron around.

See Return of Ultraman

Buttmonkey: Due to being constantly bossed around by Kelbeam (who decides to let Earthtron do all the fighting for him), which makes for some funny communication scenes between the two that intentionally parallel Adjutant Toriyama and Maru.
Non-Malicious Monster: Earthtron was only attacking because of Kelbeam's mind control. After GUYS manages to end Kelbeam's control over Earthtron, the latter monster attempts to leave, only for Kelbeam to attack him and the enraged Earthtron goes back into the fight, forcing Mebius to kill both of them.

Chronorm

First Appearance: The Ocean Waves of Time

A nudibranch-like beast that travels across the universe in search of memories to consume. It warps people to the exact time and place of the memory it wishes to eat and then kills their past self, erasing the victim from existence. When it arrived on Earth, it targeted Marina's summer childhood, warping her, Torii, and Mirai into the past.

Achilles' Heel: Destroying Chronorm's eyestalks nullifies its time-warping powers.
Arch-Enemy: To Torii for destroying his people.
Brown Note: Its warping abilities make the sound of ocean waves, which is what warps victims (or anybody else unlucky enough to hear them) through time.
Combat Tentacles: Can sprout two from its front which it uses to fight Mebius.
Eldritch Abomination: Giant monster that consumes memories, warping victims to the time and location of the memory to eat their past self yet...
- Animalistic Abomination: ...it resembles a giant sea slug.
Eye Beams: Chronorm can charge up a red orb of energy from its eyes to be launched at foes.
Eye Scream: Marina blows out the monster's eyestalks as they're the source of its warping powers.
Interim Villain: Right after the lesser Bogals are dealt with but before Yapool's returns not having a connection with either Arc Villain.
Invisibility: Can spray a white mist to turn itself invisible.
Shock and Awe: Its tentacles can generate powerful electric shocks.
Time Master: Combined with the ability to consume memories.
Would Hurt a Child: Chronorm's goal in the episode was to kill the child Marina.

Alien Angel Torii

https://static.tvtropes.org/pmwiki/pub/images/angel_seijin.jpg

First Appearance: The Ocean Waves of Time

Played by: Ryuichi Ohura

The last of the aliens of Planet Angel. All of Torii's kind had been devoured by Chronorm and he escaped to Earth disguising himself as a human. There, he soon learned that Chronorm had come to Earth and hired Marina to assist him in subduing the monster.

Animal Motifs: Birds, specifically albino peacocks.
Bilingual Bonus: Torii's name is Japanese for "Bird".
Bird People: His species.
Go Out with a Smile: He dies happily knowing that his sacrifice is what allows Marina and Mebius to kill Chronorm, avenging his people and giving the young Marina the courage of her future self.
Heroic Sacrifice: Torii performs one to save Marina from Chronorm when she gets distracted by her past self's injuries.
Last of His Kind: Chronorm ate most of them. The few others that escaped died on the journey to a new home.
Nice Guy: Torii was gentle, very friendly, and very sincere to others.
Our Angels Are Different: A race of graceful bird-like aliens all wiped out by a giant space slug.
Winged Humanoid: Of course.

Vakishim

First Appearance: The Resurrection of Yapool

The first Choju brought back by Yapool when he returned after the events of The Movie. The evil entity used it to capture Ryu and possess him in order to torment Mirai, later siccing the Choju on Phoenix Nest when the Yapool-possessed Ryu sabotaged GUYS.

See Ultraman Ace

Mythology Gag: Yapool possesses Vakishim to battle an Ultraman...again.
Tractor Beam: In this series, Vakishim possesses one in its eyes that allows it to capture humans and bring them into Yapool's dimension for him to use.

Doragory

First Appearance: Program of the Poisonous Moth

The second Choju resurrected by Yapool. This Doragory is the original one, so it still remembers its original purpose (prevent a missile from destroying a comet about to hit Earth). It possessed Dr. Fujisawa in order to fulfill this mission, believing her work on developing the Dimensonal Dissolver for GUYS was going to be used to stop it.

See Ultraman Ace

Back from the Dead: This Doragory is the original one from Ultraman Ace revived by Yapool, complete with its original memories
Continuity Nod: To the original two-part episode it debuted in "Kaiju vs Choju vs Seijin" and "Life of the Sun, Life of Ace".
- Additionally, Teppei freaks out when Doragory manages to pin down Mebius, stating that "Doragory ripped apart Muruchi in the past". Thankfully for Mebius, no dismemberment occurred thanks to GUYS' intervention.
Demonic Possession: In its moth form by turning itself into purple as to enter Dr. Fujisawa's body.
Moth Menace: Doragory can now transform into a giant moth in order to possess people.

Velokron

First Appearance: Soaring to Tomorrow

The third Choju to be brought back by Yapool. Velokron was sent out to injure Captain Sakomizu and prevent GUYS from successfully utilizing their Dimensional Dissolver to seal off Yapool's Dimension from theirs for the prevention of further Choju attacks.

See Ultraman Ace

Irony: In it's debut, Velokron is the first of Yapool's choju Terrible Trio introduced (and the very first choju in the franchise). Here it appears after it's fellow choju Vakishim and Doragory.

Maquette Zetton

First Appearance: Champion of Fierce Fighting

GUYS' choice for a third Maquette Monster, which quickly went rogue due to its capsule being accidentally damaged by Toriyama. Due to the Maquette battle testing zone being inside a computer, the rogue Zetton threatened to destroy GUYS' software in its rampage.

See Ultraman TV Series

A.I. Is a Crapshoot: The Maquette Monster went rogue as Toriyama had damaged its capsule, meaning GUYS could no longer control such a powerful monster anymore.
The Dreaded: Mirai is pretty nervous about having to battle Zetton, even if it's just a Maquette version, due to how infamously powerful the monster is.
Mons: A rogue one in this case.
Mythology Gag: Maquette Zetton defeats a Maquette version of Mebius in the exact same way the original Zetton killed the original Ultraman. They even parody Ultraman's death scene when Maquette Mebius collapses.
Shout-Out: The concept of a digital monster that the hero has to battle in the virtual world isn't new for Tsuburaya Productions, as those who have seen Denkō Chōjin Gridman will tell you.

Nova

First Appearance: Konomi's Treasure

A Flying Saucer Beast that somehow snuck into Phoenix Nest unseen and began to siphon Maquette energy, creating a miniature Maquette version of itself that began haunting GUYS' base in a scheme to eventually make a full-sized replica as a red herring.

See Ultraman Leo

Our Ghosts Are Different: The Maquette Nova begins as a ghost-like entity haunting the Phoenix Nest, spreading rumours of a spectre in the base.
Mons: Nova creates a Maquette version of itself by stealing the energy that creates Lim. Eleking.
More Teeth than the Osmond Family: This particular Nova turns out to have hundreds of teeth when in Maquette Form, though it lose them upon turning to a kaiju.
Nightmare Face: When it's Maquette form does a Slasher Smile at the camera. You know, for kids!
Red Herring: The Maquette Nova it created was intended to distract GUYS and waste Mebius' colour timer energy while the real deal attacked Phoenix Nest.
Slasher Smile: In it's ghost form, Nova delivers a surprisingly scary, legit jump-out-your-seat scary smile at the camera. It's actually rather unsettling from up close.
Smoke Out: Unlike the original Nova whose red smoke was capable of driving people insane, this Nova on the other hand only uses this attack as a smokescreen.

Roberuga

First Appearance: The Hopes of Comrades

Voiced by: Hisao Egawa

A Flying Saucer Beast formed by Empera from the remains of the Black Star. Roberuga was sent to kill Mebius shortly after his exhaustive battle against the first Imperiser. A second Roberuga later came to Earth, only to be defeated in the South Pacific by Mebius and Ultraman 80. A third then appeared with the arrival of Armoured Darkness, but Fire Windam eliminated the monster.

Art Evolution: The second Roberuga is yellow instead of red.
Continuity Nod: The Black Star from which its remains were made from was the planet that the Flying Saucer Beasts of Ultraman Leo came from, which also makes Roberuga the only one of the Living Saucers to have never been under the control of Commander Black.
Cyber Cyclops: Essentially, though it's not clear how much of Roberuga is robotic.
Eye Beams: Shoots purple energy bolts from its eye.
Hand Blast: Roberuga's preferred tactic is to spam purple orbs of explosive energy from its hands.
Madness Mantra: The first Roberuga only muttered "Obliterate Ultraman Mebius".
Robeast: Formed from some combination of cybernetics and organic parts.
Spell My Name With An S: Also translated as Roberugal or Lobegal, due to the "L-R" confusion of the Japanese language.
Voluntary Shapeshifting: Can transform into a flying saucer like all other Flying Saucer Beasts, but unlike the rest, Roberuga's body is totally retracted into the spaceship-like head rather than simply curled up into the appropriate shape.

Alien Mates Beo

First Appearance: The Monster Master's Legacy

Voiced by: Toshinori Yoshida (also human form actor)

The son of the original Alien Mates. Beo came to Earth to fulfill his father's hopes of creating a friendly relationship between humans and his people, but brought along Zoa Muruchi just in case things got hostile. Unfortunately they did, leading to another conflict between Earth and Planet Mates.

See Return of Ultraman

Continuity Nod: To "The Boy and the Monster Master" from Return of Ultraman.
Spell My Name With An S: Sometimes spelled Bio.
You Killed My Father: He came to Earth to try fulfill his father's ideals initially, albeit with greater caution. It soon turns into bitter vengeance when Ryu mistakes him for a hostile and shoots him.

Zoa Muruchi

First Appearance: The Monster Master's Legacy

A variant of Muruchi brought by Beo just in case negotiations with Earth went the way of his father's attempt. When things went exactly as Beo feared they would, he called the monster forth to destroy a nearby town as his way of repaying humans for their hatred.

See Return of Ultraman

Art Evolution: Zoa Muruchi possesses green fins and dark blue spots on its body while its skin is a lighter shade of blue. Otherwise, it is the exact same as the original Muruchi.
Mythology Gag: Muruchi does a Battle in the Rain with an Ultraman again.
The Power of Hate: Beo explains to GUYS that Zoa Muruchi is literally driven by Beo's own anger towards humans for the death of his father. Appropriately, "zoa" is supposed to mean "hate" in the Mates' language

Femigon

First Appearance: Lady of the Blue Flame

A monster that possessed a lovely new classmate of Teppei named Misa, giving her pyrokinetic powers. Unlike what happened with Ultraman Jack and the original Femigon, GUYS faced a serious crisis as they ran the risk of killing Misa if they destroyed Femigon.

See Return of Ultraman

Synchronization: Unlike MAT, GUYS is faced with the fact that if they destroy Femigon, its host will die. In fact, Ultraman Jack's defeat of Femigon in Return of Ultraman is retconned to explain that his Specium Ray's energies were somehow able to separate the monster from its host.

Alien Reflect

https://static.tvtropes.org/pmwiki/pub/images/reflecto_new.png

First Appearance: The Man Without a Home

Voiced by: Hirohiko Kakegawa

An alien with armour-like skin that deflects all energy attacks, Reflect came to Earth to defeat Ultraman Mebius. As Mebius could not bypass Reflect's powerful shell, he had to turn to Ultraman Leo in order to learn the techniques that would defeat the alien. Alien Reflect also made a brief appearance in Ultra Galaxy Mega Monster Battle NEO.

A Taste of Defeat: What he showed to Mebius, as well as his reaction to having his wrist shield broken by the Mebium Drill Kick.
Arm Cannon: On his left wrist shield.
Attack Reflector: His skin acts like a mirror, reflecting all forms of light up to and including Ultraman beam attacks. He can also catch beam attacks with his bare hands and shoot them back out of his "mouth".
Blade Below the Shoulder: His preferred melee weapon, hidden in his right wrist shield.
Expy: Not of anyone specific, but rather all the aliens and monsters in the first few episodes of Ultraman Leo. Like them, Reflect had a technique or ability that made him difficult for the hero to kill, forcing them to train and find a way to defeat the villain and overcome their powers.
Faux Affably Evil: He at first behaves rather politely and calm for an alien invader, once he defeats Mebius he finds killing him unsatisfying since he considers him weak and spares him so he can try again to defeat him (though fully expecting to win and kill him the second time around), and he proves patient enough to not cause any destruction on Earth while awaiting his challenge and seemingly plays fair as soon as the fight starts. But the moment Mebius injures him and counters his shield technique, all his honor and affability gets thrown out the window.
Grappling-Hook Pistol: On his right wrist shield. Used to capture the GUYS Phoenix to taunt Ultraman Mebius.
Luckily, My Shield Will Protect Me: His wrist shields have the same properties as his skin. He tries to use them when Mebius uses the Mebium Drill Kick and fails.
Meaningful Name: His name, "reflect", refers to his abilities to deflect all beam attacks thrown at him forcing Ultraman Mebius and Leo to fight him hand-to-hand.
No Mouth: Has a series of bars that glow when he talks.
No-Sell: Able to survive any beam attack no matter how powerful thanks to his armour. The same can't be said for intensely strong melee.
Smug Snake: Was very full of himself thanks to the self-given belief that he was invincible.
Spikes of Doom: Several spikes on his shell-like body.
Spin Attack: One of his abilities was to spin around rapidly, turning himself into a deflective weapon.
Torso with a View: Mebius and Leo defeat him by using their Diving Kicks to smash straight through his body.
Villainous Breakdown: Alien Reflect appears to be an honorable alien at first. He's well mannered in his speech, always using honorifics, and even spares Mebius after their first battle, claiming that he's too weak and doesn't even tries to rampage afterwards, instead waiting for Mebius to return for a rematch. However, after Mebius managed to damage his shield, he loses it and is quick to use the GUYS crew as hostages to try and secure his victory.

Alien Babalou

First Appearance: Azure Waves of Light and Shadow

Voiced by: Motomu Kiyokawa

Initially encountered by Ultraman Hikari when he received a suspicious message from Mebius to meet him at Aarb, Babalou impersonated Mebius to capture Hikari, but the blue Ultra defeated the alien and forced him to flee. But in an act of vengeance, Babalou headed for Earth and disguised himself as Hunter Knight Tsurugi to attack cities. Although GUYS saw through the disguise, Babalou successfully revived Japan's fears of the blue Ultra, forcing Hikari to almost literally come face to face with his past self and his crimes.

See Ultraman Leo

An Ice Person: This incarnation of Babalou possesses the ability to breathe freezing mist. This ability was used to explain how Astra was trapped in ice by the alien in his original appearance in Ultraman Leo.
Imposter Forgot One Detail: His modus operandi had him invading Earth while disguised as Hikari's form of Hunter Knight Tsurugi in order to make humans lose faith in the Ultras. However Mirai Hibino immediately figured out that it's not really Hikari because Babalou's disguise included the Knight Brace, which Hikari had previously given Mebius before leaving Earth.

Alien Psychokino Kako

https://static.tvtropes.org/pmwiki/pub/images/alien_psychokino.png

Kako is the one on the far right

First Appearance: Mirai's Younger Sister

Played by: Ayumi Takamune

One of a race of troublemakers who had destroyed their own world from abusing their psychic abilities, Kako is the leader of a small gang of her kind who came to Earth in the disguise of middle school students to make destructive mischief with the monster Angross. She also tried to pull the wool over GUYS' eyes by claiming to Mirai's younger sister. GUYS was not fooled by this, but decided to use as an opportunity to try and befriend her.

Back for the Finale: Kako returns one last time to help GUYS against Empera.
Defrosting Ice Queen: Kako starts off very cold and rather mischievous to others, but the words of Mirai leave her changed.
The Greys: Although Kako and the rest of her kind on Earth spend the majority of the episode disguised as schoolchildren, they're revealed to be this at the episode's end scene.
Meaningful Name: Since she claims to be Mirai's sister, it's only appropriate that "Kako" means "Past" in Japanese.
Psychic Powers: The whole gamut of them, including levitation, telepathy, teleportation, creating psychic shockwaves, mind and body control, and empathy. Most of these are for the sole purpose of annoying, humiliating, or even harming others.
The Trickster: Her species are a whole race of them, travelling from planet to planet to cause chaos and screw around with locals.

Angross

First Appearance: Mirai's Younger Sister

A drill-snouted, mole-like monster created out of soil by Kako and the rest of her Psychokino friends to wreak havoc across Japan through its incredible tunneling power. Angross also appeared in Ultra Galaxy Mega Monster Battle.

Achilles' Heel: Getting turned over on its back will render Angross flailing about helplessly while being vulnerable to any attack.
Drill Mole: Angross' motif.
Flipping Helpless: His main weakness, which Mebius exploits by tunneling underneath it and then knocking Angross over on it's back.
Golem: Kako made the monster out of earth to act as a servant, so it definitely could be considered one. Later appearances of Angross are left with unexplained origins though.
In a Single Bound: Angross is a very strong leaper, going far and wide in its jumps.
Red Eyes, Take Warning: Especially after Kako increases its power for the final battle.
Spikes of Doom: Three retractable ones on its back.
This Is a Drill: Its nose, though it can also act as a jackhammer.
Tunnel King: Thanks to its drill-nose, which allows it to dig far faster than any other monster.

Jashrine

First Appearance: Father's Return

Voiced by: Dai Matsumoto (Angry Face), Shintarō Asanuma (Happy Face), Haji (Sad Face)

An alien criminal and fighter from the Eridanus System who had made a reputation out of turning those he defeated to gold. He came to Earth during a festival celebrating the Father of Ultra with dreams of adding an Ultraman to his collection, turning Mebius to gold and forcing the Father of Ultra to come save the day. Jashrine also appeared in Ultraman Ginga.

Battle Boomerang: The Angry Face's combat method is a massive boomerang that works just as well as a hammer.
Collector of the Strange: He collects the petrified bodies of those he defeats.
Expy: Of Alien Hipporito from Ultraman Ace. Both are very powerful aliens with petrification abilities, and Hipporito's episode also saw the debut of the Father of Ultra, who makes a similar return to save Mebius from Jashrine.
- His status as a three-faced alien with differently coloured eyes for each face also makes him one to Dada and Gigi.
Jerkass: A cocky, sadistic, and aggressive alien.
Mayincatec: His motif is Mesoamerican totem poles.
Mind over Matter: The Sad Face uses telekinesis capable of manipulating even energy beams.
Planetary Core Manipulation: His trump card, should he fail in battle against the Ultramen (he did); by tunneling himself into the planet's core, destroying Earth and everyone on it's surface in the process in a Taking You with Me last-ditch move. However Ultraman Mebius blew him up before he could start digging.
Sore Loser: He behaves absolutely cocky and mighty when he's winning in battles, but the moment he's defeated, he immediately decides to tunnel into the earth's core to wipe out the entire planet in a Taking You with Me moment, simply out of pure spite. Mebius blows him up before he can do that.
Spell My Name With An S: Also called Jasyuline.
Spin Attack: His most powerful move asides from the Gold-Coating Ray. Capable of causing massive earthquakes that can shatter a planet.
Taken for Granite: He can fire a powerful ray of energy from his "wings" that turns targets to gold.
Two Beings, One Body / Multiple Head Case: Somewhere between both with his Angry, Happy, and Sad Faces. Each has their own distinct voice and personality, but only one face can be active at a given moment. They have a tendency to finish each other's sentences as they switch between dominance.
Verbal Tic: Each of the faces ends their sentences with a part of Jashrine's name; the Angry Face ends his with "Jaja!", the Happy Face with "Shura!" and the Sad Face with "-ine!".
Victory Dance: Performs a rather humorous one after he defeats Mebius.
Vocal Dissonance: Despite his placid expression, the Sad Face speaks with a high-pitched, screechy voice.

Arigera

First Appearance: Isana of the Ocean

An extraterrestrial monster capable of gliding through both seas and skies at incalculable speeds, which meant that GUYS had to team up with Captain Hiroshi Isana and his crew from GUYS Ocean to defeat it. Arigera also appeared in Ultra Galaxy Mega Monster Battle.

Beware My Stinger Tail: Shoots orbs of flaming energy from its tail.
Chest Blaster: Able to fire the same projectiles from its chest-mounted organic cannons.
Eyeless Face: It sees via echolocation.
Fragile Flyer: It rapid flight gives it great mobility, but it's also very physically weak. It puts up enough of a fight via organic cannon blasts, but gets killed in a single hit via Inertia Is a Cruel Mistress when it flies directly into Ultraman Mebius' Mebium Blade, halving it vertically.
Fragile Speedster: Although Arigera is one of the fastest monsters in the Ultra Series, it's shown to be physically weak.
Giant Flyer: Combines this trope with Sea Monster.
Half the Man He Used to Be: Its fate.
If It Swims, It Flies: An aquatic monster with flight abilities. It's also insanely fast at flight, capable of travelling around at Mach 6, to the point where the entire episode of its debut is spent on GUYS trying to catch up with it.
Sea Monster: Arigera is as capable of moving through water as easily as it can soar through the sky.
Super-Speed: Uts basic gimmick, thanks to the organic thrusters on its back. It moves so fast that it creates literal sonic booms.

Alien Serpent

https://static.tvtropes.org/pmwiki/pub/images/serpento_better.png

First Appearance: The Invincible Mother

Voiced by: Tetsuo Sakaguchi

Alien invaders, sent by Alien Empera, whose leader merged with a loving mother and wife, as well as lunchlady at GUYS' mess hall, named Sayuri Hinode after she was killed in a car accident, promising to let her see her children and husband once more if she helped them with his mysterious agenda.

Bitch in Sheep's Clothing: The Serpent leader told Sayuri she could see her loved ones as long as she fulfilled some important duties to him. She had no idea they were just using her as a pawn to open an invasion gateway inside Phoenix Nest.
Deal with the Devil: What Sayuri essentially did with the Serpents to see her family again.
Demonic Possession: Something akin to an evil version of the Ultramen's merging powers.
Elemental Shapeshifter: Due to being composed entirely of water, they are able to turn into living puddles of water at will.
Expy: Their design was based off Alien Hook and Alien Borg, primarily in their ridged and featureless faces, metallic bodies, and simplistic clothes.
Evil Counterpart: Of the Ultramen. In fact, the scene where Sayuri and the Serpentian leader become one is a shot-for-shot imitation of what happened between Goh and Ultraman Jack in Return of Ultraman.
Faux Affably Evil: The Serpent leader allegedly merged with Sayuri out of admiration towards her courageous sacrifice, but in reality he was just using her as a vessel to invade Phoenix Nest and had no concern over her safety.
Fusion Dance: The Serpents fuse themselves into a giant-sized being for the fight with Ultraman Mebius.
Half the Man He Used to Be: After being weakened by salt, the final Serpent Alien get sliced into chunks by Mebius.
Hand Blast: They can shoot blue blasts of energy from their wrists.
Healing Factor: As long as they're exposed to moisture, this applies.
Hoist by His Own Petard: The lead Serpent did not expect Sayuri's willpower to see her loved ones again to be stronger than his ability to take over her body.
Salt Solution: The Serpent Aliens' bodies are greatly weakened by salt, to the point of crumbling apart upon contact.
Weaksauce Weakness: Salt, as their bodies are almost entirely made out of water.

Solitura & Soliturans

Solitura

First Appearance: Lonely Paradise

A creature that traveled across the universe assimilating life from planet to planet. It landed in a Japanese forest, assuming a tree-like form and creating Soliturans that would target lonely and miserable people to be assimilated into the monster's form.

The Assimilator: Absorbs life into its mass, but since it can't move, the Soliturans look for the victims. It also takes on the form of its surroundings, as it first appears as a mass of pale white tendrils that then gain a woody texture and pile themselves up into the form of a tree monster upon grabbing some trees.
Half the Man He Used to Be: His fate.
Lotus-Eater Machine: Solitura's power is to put victims into a state of happiness and bliss in such a fashion while it assimilates them.
Meaningful Name: Solitura's name is Latin for "loneliness", as its minions target people unhappy with being alone in life.
Mook Maker: Creates Soliturans from the flowers on its mass to collect victims. The Soliturans can also remerge with Solitura as needed.
Mythology Gag: Solitura appears to be amalgamated from a few plant-based monsters in the franchise. It's constant use of poisonous pollen is lifted from Zora, it can induce human victims into a catatonic state like Jagira, while appearance-wise it seems to be based off Gijera.
Planetary Parasite: Essentially what Solitura is — a monster that assimilates all life on a planet, merging their consciousnesses and the planet with itself.
Poisonous Person: Sprays poison pollen from its forehead.
Spell My Name With An S: Also known as Sorichra.
Vine Tentacles: Has a couple of thick ones for grabbing and smashing Ultraman Mebius.
When Trees Attack: Takes on the form of a tree kaiju upon the immediate assimilation of its forested surroundings, though it can disassemble this form to remain hidden until it desires to attack.

Soliturans

https://static.tvtropes.org/pmwiki/pub/images/solituran.jpg

First Appearance: Lonely Paradise

Voiced by: Nobuhiko Tanaka (also human form actor)

Flower-headed men created by Solitura to search for victims. They disguise themselves as ordinary people and targeted lonely and miserable humans with temptations of paradise.

Foul Flower: They're flower-headed people spawned by flower growing from Solitura's body and then sent to find victims for assimilation.
I Am Legion: The Soliturans call themselves "we", as they are offshoots of Solitura rather than individual beings.
In the Hood: Their human forms, wearing hoods like creepy cultists.
Plant Person: Their true form is essentially a humanoid mass of vines with a flower-topped head.
Poisonous Person: They possess the same poison pollen as Solitura, which paralyzes the nervous system.
Spell My Name With An S: Sometimes called Sorichrans.
Voluntary Shapeshifting: They disguise themselves as white-robed humans to make their search for victims easier.

Hoe

First Appearance: Teacher's Memories

A Minus Energy monster formed from massive amounts of Minus Energy created when the original class of Takeshi Yamato gathered at the soon-to-be-demolished Sakuragaoka Middle School for a final reunion where they hoped to reunite with their teacher again.

See Ultraman 80

Continuity Nod: Shinji, whose Minus Energy had created the original Hoe in Ultraman 80 appears in the episode, and his old classmates ask him if he somehow did it again when Hoe reappears.
Face Death with Dignity: Once Ultraman 80 arrives, Hoe is simply willing to let the Ultra end his existance, standing on the spot for 80 to erase him via Buckle Beam.
Intangibility: Due to being formed from a cluster of Minus Energy, every beam attack either from Mebius or GUYS simply phases past Hoe harmlessly.
Non-Malicious Monster: Hoe doesn't attack its surroundings, as it was conjured by Sakuragaoka Middle School in an effort to bring back Ultraman 80 to see his students one more time. When 80 shows up, Hoe doesn't even fight back and lets him kill it.
Tragic Monster: It ultimately represents the desire of 80's students to see their old teacher that they never said goodbye to, again. Instead of attacking its surroundings in rage, it attacks Mebius in pure grief and even cries tears as it fights him, only calming down when 80 arrives.

Gadiba

First Appearance: A Visit From an Old Friend

Yapool's personal pet, Gadiba is a Choju unique in its ability to steal the DNA of other lifeforms and either duplicate them or increase the power of others with it. It assimilated Gomora and Red King to take their forms to fight Ultraman Mebius. Later, Yapool used Gadiba to create Mebius Killer, using the information it had acquired on Ultraman Mebius in their initial encounter.

The Assimilator: Gadiba assimilates the DNA of other monsters in order to take their forms, which it does to Gomora and Red King. Worse still, it can steal the DNA of those it battles in order to strengthen other monsters, like using Ultraman Mebius' powers to create Mebius Killer.
Continuity Nod: To assimilate Gomora and Red King, Gadiba visits Johnson Island and Tatara Island, where the original ones appeared in Ultraman.
Evil Doppelgänger: In its Gomora and Red King forms, which also benefit from being more powerful than the standard versions.
Fog of Doom: It's a Choju made entirely of smoke.
Knight of Cerebus: Though GUYS doesn't realize it at the time, Gadiba's appearance marks the beginning of the series finale's 4 Heavenly Kings story arc and the buildup to the arrival of Empera.
Pet Monstrosity: Unlike other Choju, it's more of a pet to Yapool than a weapon.
Red Eyes, Take Warning: Its only clear features.
Shapeshifter: Takes on the form of Red King to battle GUYS, but after being defeated by Mebius, it immediately transforms into Gomora for Round 2.

Mebius Killer

First Appearance: Threat of Mebius Killer

Voiced by: Ryoichi Tanaka (in Ghost Rebirth)

The resurrected Ace Killer, this time empowered with the information amassed by Gadiba needed to destroy Ultraman Mebius by giving it Mebius' powers. Later, when the 4 Heavenly Kings are revived in the Monster Graveyard, Yapool is trapped in the body of Mebius Killer, granting the Choju the ability to speak.

See Ultraman Ace

Art Evolution: The original Ace Killer was a silvery colour in Ultraman Ace. Mebius Killer is more golden this time and also wears a Mebium Brace.
Back from the Dead: In Ultraman Mebius Gaiden: Ghost Rebirth with Yapool possessing it.
Suddenly Voiced: In Ghost Rebirth, due to the fact that Yapool is trapped in the Choju's body for unknown reasons.

Lunatyx

First Appearance: Ace's Wish

A Choju sent by Yapool to destroy GUYS when he lured them with the Space-Time Emitter to the Moon while he isolated Mebius. Fortunately for GUYS and Mebius, Ultraman Ace helped to battle the rabbit-like monster while the team focused on other priorities.

See Ultraman Ace

Mythology Gag: Lunatyx's appearance in this series marks the reunion of Hokuto and Minami, who had separated since Lunatyx's debut in Ultraman Ace.

https://static.tvtropes.org/pmwiki/pub/images/ayamebius.png

Played by: Aiko Ito

A marine biologist and oceanographer who Mirai befriends when he comes to Kobe to investigate mysterious energy signatures in the waters off the coast.

In her following appearance, she is almost shot down by Giant Yapool when she tries to encourage Mebius to keep fighting.
Neutral Female: Aya may be part of GUYS, but as an oceanographer, she doesn't really have any significant combat abilities and is largely a Damsel in Distress when it comes to dangerous situations, but that doesn't stop her from motivating Mebius when things get grim.
Nice Girl: She's friendly toward Mirai the moment she meets him and is a fairly likable person overall.
Ship Tease: She develops feelings for Mirai and later asks him to spend a day with him in episode 43.
