- Badass Teacher: Is a teacher both on his home planet and Earth. In fact, his entire plan is to teach human children to be more positive and kind to counter Minus Energy. Given it's a long time until Earth faces monsters and aliens again after his departure, one can't argue with the results.
- Demoted to Extra: Ultraman 80 is not the most publicized main series Showa Ultra. Aside from his appearances on Ultraman Mebius, he has only made two different appearances in film, both of which are Ultraman Zero films.

- Cats Are Mean: He resembles a tall, slender felinoid creature, with cats being his primary design motif.
- The Heartless: Hoe is representative of negative emotions more than any other Minus Energy monster, especially of jealousy and anguish, from which it was spawned by.
- Hollywood Acid: Hoe constantly cries tears of explosive acid.
- Intangibility: Albeit only towards the majority of beam attacks. Punching and kicking him works fine though.
- No-Sell: Due to the fact that Hoe is completely made of Minus Energy, most beam attacks phase through its body.
- Spell My Name with an "S": Sometimes just spelled Ho.
- First Appearance: From the Skies With Love
- Blow You Away: Like all winged kaiju, Zandrias and his mother can create hurricanes by flapping their wings.

- Eye Beams: Only the mother was shown using it, but it can be assumed the juvenile also had the ability as well.

- Eye Beams: Abdolarus' sole power is to fire lasers from his yellow eyes that either explode on impact or electrify whatever they hit.

- Spell My Name with an "S": Also called Aruma.
- First Appearance: The Visitor from Space
- Energy Absorption: Jakki absorbs the Minus Energy generated from what it witnesses (like two men fighting over a car accident or kids bickering over a pencil), which is how it becomes corrupted.
- Flying Seafood Special: Capable of flying about despite resembling a sea snail, which is how it escapes so quickly from Alma.
- Pet Monstrosity: Of Alma, though it's generally pretty harmless.
- First Appearance: The Visitor from Space
- "Fantastic Voyage" Plot: Similar to what Ultraseven did with Darii back in 1967, Ultraman 80 doesn't fight Zruzular, but has to go inside it to subdue Jakki.
- Making a Splash: Like normal elephants, Zruzular can suck up water and spray it from his trunk, which he uses in his battle against UGM.

- Cyclops: They have a single red eye.
- First Appearance: Formation Yamato
Salamandoras is also one of the few Ultraman 80 monsters to appear against other Ultra heroes, but references to its alien masters were dropped with the regeneration reworked into a natural ability caused by the throat patch actually being a highly sensitive organ that allows for the regeneration.
- Achilles' Heel: It has a patch on its throat that when shot, causes it immense pain, so UGM has to figure out how to get the monster to expose the underside of its neck. This was retconned in Ultraman Mebius to explain that the soft spot is the monster's regeneration organ.
- Attack Its Weak Point: The throat patch is recognizable as a brighter and lumpier bit of skin near its chin.
- Breakout Villain: Due to being one of the few kaiju new to this series to appear in subsequent Ultra Series, starting with Ultraman Mebius, Salamandoras is one of the more popular monsters in this show.
- Breath Weapon: Breathes fire.
- Everything's Better with Dinosaurs: Strongly resembles one, though the real inspiration was salamanders (as the name gives away).
- From a Single Cell: The Gorgon aliens keep a cell of the monster to regenerate it completely if it is destroyed. Retconned in Ultraman Mebius into a default ability of the monster that can only be neutralized by attacking its Achilles' Heel.
- The Juggernaut: As if the regeneration wasn't bad enough, is thick skin means that Ultra beam attacks do very little to harm it.

- Eye Beams: Can fire purple lasers from his eyes.

- Music Soothes the Savage Beast: Only Emi's singing was able to calm down Myu when it was turned into a kaiju due to the bond she had forged with the small monster when it was being studied by her father Dr. Jouno.

- Sealed Evil in a Can: Was imprisoned in a snowflake-like object by Alien Ruria, but ultimately escaped as a result of human curiosity and a fascination for the prison's beauty.

- First Appearance: Flight to the Eerie Monster Island Pt. 1
- Beast and Beauty: Even when kaijufied, the only creature Chief Ito will not harm is Sawako. Unfortunately, UGM mistakes their first encounter with her and Raburas to be the monster kidnapping the lady.

- Was Once a Man: Chief Ito had taken a vacation to the resort island that Gimyra had taken over, turning the second-in-command of UGM into the first victim of his monster-mutating powers. Fortunately, he still retains a shred of his human memories that UGM and Sawako are able to unlock and bring him to his senses.

- Giant Squid: Is an octopus kaiju.

- Mind Control: Gimiyra's primary ability is to mentally subjugate both humans and other monsters, so long as he has already drank some of their blood.
- Overly Long Tongue: Which he uses to drink the blood of his slaves. It also has multiple tips and can be used like an electrified whip.
- Our Vampires Are Different: While he obviously doesn't resemble anything like a traditional vampire, Gimyra's bloodsucking traits (even leaving strange bitemarks) and his ability to mind control people or transform them into monsters after drinking their blood are very reminiscent of one.
- Shock and Awe: Gimyra's tongue can conduct electricity to shock foes.
- Spell My Name with an "S": Also spelled as Gimaira, Gimira, and Gymaira.
- First Appearance: Rogue Star Destruction Directive
- Expy: Nearly everything about Gauss except his appearance is inspired by Starbem Gyeron from Ultraseven, as in being a "Nuclear Nasty whose planet was blown up by the defense team".

- First Appearance: Shine On, Space G-Man of L85!Played by: Takeshi Obayashi (voice and suit actor)
- Anti-Hero: Although Zuckal serves in an organization with many of the same goals as the Ultramen and is quite admirable in his quest to kill Gamos, he is so consumed by revenge that he refuses to let even Ultraman 80 stand in his way, despite Takeshi's requests to assist him.
- Hulking Out: He can transform into a giant, monstrous version of himself, but doing so will kill him, so he only saves it for what he believes will be his final battle with Gamos.

- First Appearance: Planet of the Traitorous Androids

- Humongous Mecha: It's a giant spaceship robot.

- Breath Weapon: Breathes an energy beam.
- Everything's Better with Dinosaurs: He strongly resembles one with crystalline spikes.
- The Reptilians: He's not called Alien Argon and looks more like a typical kaiju, but he flies a spaceship and can turn into a human and interact with them like normal, so he most certainly is meant to be a reptilian alien.
- First Appearance: Shadow Samurai in the Tunnel of TimePlayed by: Yuu Ishiyama (Akuzone leader)
- Multiversal Conqueror: The Akuzone intended on taking over as many dimensions as possible, including Yomi. Whether they had plans to seize Earth next though is unstated.

- Weakened by the Light: Argo is incapacitated by bright flashes of light.
- First Appearance: Lullaby for a Migrating Monster

- Gentle Giant: Baru are very large monsters, but perfectly peaceful creatures.
- Giant Flyer: They migrate throughout space in large flocks.

- Spell My Name with an "S": Also call Val, Bal, and Varu, because in the Japanese language "B" and "V", as well as "L" and "R", are often confused together.
- First Appearance: Lullaby for a Migrating Monster
- Eye Beams: Its primary ability, which it uses to kill Barus, sending chunks of their flesh crashing to Earth.

- Breath Weapon: Breathes a cloud of highly explosive mist.
- Everything's Better with Dinosaurs: Looks like a bog-standard dinosaur-type kaiju until Ultraman 80 busts its armour open.
- Humongous Mecha: Zatan Silver doesn't look quite as robotic as Mecha-Gillas or Robo-Fo, but it becomes clear the silvery skin isn't merely natural armour once Ultraman 80 reveals the wires and circuitry inside.
- The Juggernaut: Zatan Silver's metallic armour is highly resistant to Ultraman 80's Finishing Moves. However, a series of powerful punches and kicks were enough to break open the armour as well.

- Expy: Of Iron Rocks from Ultraseven, the only other ship-based kaiju in the Ultra Series.
- Humongous Mecha: It's a giant robot ship that increases its mass by amassing other ships!

- Hand Blast: Able to shoot an energy beam from its massive right fist.
- The Heartless: Being a Minus Energy Monster and all that.
- The Juggernaut: Ultraman 80 had a lot of trouble with this guy until he discovered its Achilles' Heel as Gazera was unfazed by even the Saxium Beam.

- Making a Splash: Can spray high-pressure water from its mouth.
- Monster Is a Mommy: It's reason for rampaging was to try to find its disappeared child.

- Breath Weapon: Obviously, he breathes fire, but Fire-Draco can also shoot a beam of energy from his red head.
- Multiple Head Case: Each of Fire-Draco's three heads has its own personality, appearance, and powers. In fact, when the monster was originally defeated long ago, the heads' souls reincarnated as three separate humans.
- Our Dragons Are Different: While his body is fairly typical for a kaiju and name is suggestive of a western dragon, all three of Fire-Draco's heads are modeled after Japanese dragons.
- Playing with Fire: The red head breathes fire, as the monster's name suggests. Helps that Kubiryu, the red head's reincarnation, is a fire-eater.
- Sealed Evil in a Can: Fire-Draco's essence was sealed inside a magical gemstone by the priest who defeated him originally, but as legend prophesied, the monster would be reborn if its reincarnations managed to get a hold of the jewel.
- Token Good Teammate: Mitsuo, the reincarnation of the monster's white head, is the only one of the three who doesn't want to return as Fire-Draco and is mostly forced into the ordeal by Kubiryu and Takeshi since he's just a kid. He even helps Ultraman 80 against the other two heads during their battle, allowing 80 to eventually separate Mitsuo from the monster to continue living his life as a human.
- Use Your Head: The blue head can swing itself like a club to bash opponents, which in its human reincarnation, Takeshi, comes in the form of being able to bend steel with his forehead.

- The Power of Hate: Kuwaganda came to life as a result of kids getting angry over the death of a prized stag beetle, thus is powered by their grudges towards each other. The monster is significantly weakened once 80 gets the kids to let go off their hate, and returns to its burial spot shortly afterwards.
- First Appearance: Alien Baltan's Dreadful Zoo OperationVoiced by: Mizuzi Tetsuo (first appearance), Minoru Nishimura (second appearance)

- First Appearance: Did You See the Zero Fighter Plane, Monster Bird?
- Gentle Giant: Fortunately for 80, Barebadon is a completely peaceful creature that only comes to Earth every fifty to sixty years to rest during its intergalactic wanderings.

- Kick the Dog: He kidnaps, tortures, and eventually kills Emi.

Plazma and Minazma
- First Appearance: 80's Greatest Challenge
- The Dividual: For all intents and purposes, their combined threat is generally treated as a single monster.
- Fat and Skinny: The short and stocky Minazma is the fat to the tall and more leanly-built Plazma's skinny.
- Fusion Dance: They can merge themselves into Plazma-Minazma by attaching to each other's backs, becoming nigh-invincible.
- Horn Attack: Both monsters can shoot lasers from their horns, with Plazma firing one and Minaza firing two.

However, UGM had requested Takeshi and Ryoko not to transform as they wanted to prove that humanity no longer needed the protection of the Ultramen and would be able to take care of any future monsters by themselves.
- Hoist by His Own Petard: The same freezing gas that Margodon uses turns out to be the perfect way to defeat it, thanks to its extremely brittle body.
- Literally Shattered Lives: UGM destroys Margodon by using a gigantic wrecking ball to smash it to pieces
