The characters of the Medabots anime:
- Voiced by: Michiru Yamazaki (JP), Samantha Reynolds (seasons 1-2), Julie Lemieux (Spirits) (EN), Yensi Rivero (LA), Rafael Alonso Naranjo, Jr. (SP)
The main protagonist. Ikki is a relatively normal 10-year-old obsessed with Medabots who dreams of owning his own. Under pressure from some thugs, he spends all of his savings on an outdated KBT-Type named Metabee.
- All of the Other Reindeer: At first he was made fun of because he didn't have a Medabot, then it was because his Medabot is an older model. Once he starts winning his way to the top, this stops cold.
- Book Dumb: He knows a ton about Medabots, to the point where he's almost on Dr. Aki's level. But he's not very good in school.
- Dragged into Drag: In the GBA game, Ikki is forced to wear female clothing at least three times, much to his chagrin. You can change him into said articles of female clothing at will after beating the game.
- Dude, Where's My Respect?: Even his own Medabot doesn't respect him, at least at first. Even when this starts to change, his friends still don't give him a break.
- Has a Type: He seems to have something for Dr. Aki's relatives, judging from the anime.
- Instant Expert: Because of his encyclopedic knowledge of Medabots and sharp strategic mind, he's able to become the third best Medafighter in Japan after less than a year with Metabee.
- Intergenerational Friendship: With Hikaru/Henry (at least a decade older than him), whom he ends up seeing as a Big Brother Mentor.
- Kid Hero: Ikki is ten years old. Metabee comes equipped with a revolver, sub-machinegun, and seeker missiles.
- The Leader: During the Tournament Arc, he's the de facto leader of Team Japan, largely because Space Medafighter X is rarely around, and because he's the one coming up with all of the strategies.
- Nerd Action Hero: Being a nerd in this universe is made significantly more badass by My Little Panzer, but Ikki also pulls off some physical feats that would make Rambo jealous.
- Pottery Barn Poor: A point is made that Ikki is the only kid in town without the money to buy or maintain a Medabot, yet, judging from his home and neighborhood, he's actually doing pretty well. The problem seems to be more that his parents don't use any of their disposable income on him.
- Precocious Crush: He develops one of these on Nae in Spirits/Damashii.
- Red Is Heroic: A Kid Hero with a primarily red outift, in what seems to be an intentional invoking of this trope.
- Ship Tease: With Arika, in some episodes. In the GBA game it's possible to have a Relationship Upgrade with her (or with Karin) depending on the player's decisions.
- The Strategist: He is an excellent example of pulling well-built strategies as he often takes advantage of the terrain.
- Vitriolic Best Buds:
- With Metabee, since they treat each other as siblings, instead of master and "pet".
- Also with Arika, mostly because they are best friends.
- To Be a Master: He started off just wanting to have a Medabot at all. Once he gets one, he wants to be the best robattler in the country.
- Toy Ship: Him and Karin or him and Arika. The anime shows no real preference.
- Trademark Favorite Food: He takes his passion about takoyaki, as something very serious.
- Voiced by: Eri Sendai (JP), Lisa Yamanaka (seasons 1-2), Bryn McAuley (Spirits) (EN), Anabella Silva (LA), Beatriz Berciano (SP)
Ikki's tomboyish best friend. She's a highly skilled investigative reporter... in her own mind, at least.
- Alliterative Name: As long as you spell her name with an "a"
- Boyish Short Hair
- Dub Name Change: From Arika to Erika in the English translations. Averted in Latin America, when her name remains.
- Green-Eyed Monster: She's jealous of Karin due to her popularity and Ikki's crush on her. To a lesser extent, of Nae as well.
- Intrepid Reporter: Arika is one of the reporters of her school's newspaper, and is always in search of a scoop. She's almost always carrying around some kind of camera and she won't drop a story despite the danger.
- In fact, a majority of the arcs in 2 Core start with her searching for a scoop and Ikki tagging along.
- School Newspaper Newshound: She is the only member of the school's Newspaper club.
- Ship Tease: With Ikki and also later on with Team Iceland's leader Belmont.
- Tsundere: A tomboyish dere, as she is sweet and kind, but she is also violent.
- What Beautiful Eyes!: According to Belmont, they "shine like the Arctic Ocean in summer".
- Voiced by: Reona Yokomaku (JP), Joanne Vannicola (EN), Gonzalo Fumero (LA), Juan D'Ors (SP)
Ikki's main rival. A snobby, highly competitive boy from Hanazono Academy/Rosewood Private School.
- The Ace: He's rich, intelligent, and the second best medafighter in the country. Before he met Ikki, he effortlessly won every single one of his robattles.
- Badass Normal: He's the only person in Japan's top three that doesn't have a Medabot with a rare medal.
- Alliterative Name: He gets a bonus, since his last name is alliterative on its own.
- Always Second Best: Played with. He feels this way towards Ikki, despite technically being ranked higher, because Ikki was a nobody before he became number three in the country, and his Medabot can use the Medaforce. In a more official sense, he's this to Space Medafighter X: if not for him, Koji would be the best in Japan, and the gap between the two of them is vast.
- Berserk Button: He absolutely hates it when he thinks the spirit of competition is being disrespected. He loses his cool with cheaters and Medafighters that don't fight to their fullest.
- Bishōnen: He is mentioned as being a charming boy. He is also accompanied by Bishie Sparkle sometimes, though this isn't played very seriously.
- Chick Magnet: He has a lot of fangirls at his school. He only has eyes for Karin, though.
- Childhood Friend Romance: He's very protective of Karin, who he grew up with and on whom he has a massive crush. It's all one-sided on his end, unfortunately for him.
- Dub Name Change: A very odd case happens in the Latin American Spanish dub: While his given name remains the same, his surname got changed to "Taraguchi", very likely because "Karaguchi" sounds a lot like "Cara (de) fuchi" (translated as "sorry face", albeit this is normally a slang used in Mexico, and the dub of the anime was done in Venezuela, oddly enough).
- Jerk with a Heart of Gold: He's arrogant and self-obsessed, but he's not a bad guy. And when he's not being a jerk, he's actually very respectful and sportsmanlike.
- Sheltered Aristocrat: Kouji attempts to be like this and mostly succeeds, though he does sometimes slip into Upper-Class Twit territory.
- Spirited Competitor: He does like to win, but he's usually cool as long as he's satisfied with the fight. He also never takes Medaparts from opponents he defeats, because he doesn't have to.
- The Lancer: He plays this role to Ikki during the Tournament Arc. At first they struggle because their personalities and fighting styles clash so significantly, but their synergy becomes a lot better once Koji settles into letting Ikki take the lead.
- The Rival: He and Ikki start off their rivalry because of Karin, but when Koji starts to respect Ikki as an opponent, it becomes all about robattling.
- Why Did It Have to Be Snakes?: Kouji hates bugs with a passion. They freak him out so much that he's capable of going insane and destroy everything in sight.
- Worthy Opponent: Ikki wins his respect by being the first person to ever last more than a minute with him in a battle. When he's not ribbing Ikki, he makes a point to let him know that.
Hikaru/Henry Agata AKA Kaitou Retort/Phantom Renegade AKA Uchuu Medarotter X/Space-Medafighter X
- Voiced by: Ryo Naitou (JP), Jamie Wilson (EN), Ezequiel Serrano & Jhonny Torres (LA), Miguel Ángel Godó (SP)
A convenience store clerk. Also a phantom thief. Also the top Medafighter in Japan. His true identities are a secret from everyone except the viewer.
He's also the former Medabot World Champion, whose Medabot was responsible for the Medabot revolt known as the Ten Days of Darkness. His two alter-egos are both the result of this event, the Phantom Renegade steals Rare Medals so that history won't repeat itself, and Space Medafighter X allows him to robattle without revealing his identity. Like Ikki, he also used a KBT-Type named Metabee.
- Anti-Hero: Kaitou Retort/Phantom Renegade. Despite being a thief, he has his own motives to rob medals, and he has done some heroic things in the process, such as rescuing Rokusho from the Roborobo/Rubberrobo Gang, and helping out Ikki and his friends in the Final Battle.
- Berserk Button: Do not make fun of Space Medafighter X's techniques and abilities.
- Charles Atlas Super Power: Space Medafighter X is not only the best Medafighter in Japan but he can also preform the Shadow Sword himself, takes out God-Emperor/Mega-Emperor's Medal with his bare hands and personally helps fight the Big Bad's Mecha-Mooks in the Finale alongside the other Medabots using personalized shuriken.
- Cool Mask: Phantom Renegade and by extension, Space Medafighter X (since both identities wear the same mask only in different colors.)
- Cut Himself Shaving: (Dub only) Used this excuse to justify an injury he got as the Phantom Renegade. It worked despite the injury being on his forehead. (One character suggested he start waxing his eyebrows rather than trying to shave them).
- Dark Is Not Evil: Don't let his dark attire fool you, Phantom Renegade is actually on the good side. It also helps that his real name, Hikaru, means Light.
- Dramatic Unmask: Space Medafighter X loses his mask during the final arc of the first season. He has Phantom Renegade's mask directly underneath it.
- Dub Name Change: From Hikaru to "Henry" in the English dub. Also the names of his other identities have been either altered (Kaitou Retort to "Phantom Renegade") or simply translated/adapted (Uchuu Medarotter X to "Space Medafighter X").
- Evil Laugh: The Phantom Renegade has an excellent one, his calling card.
- Expressive Mask: Phantom Renegade and, to an unexplained lesser extent, Space Medafighter X.
- Hero of Another Story: There are several hints through the series that suggest that Hikaru/Henry was this before the "Ten Days of Darkness" happened. Which makes sense as he was the main protagonist of the first game.
- Idiot Hair
- Intergenerational Friendship: With Ikki, since he is younger by him by almost a decade. That is because he reminds him of himself in his childhood, and not so long after that, he starts acting as a Big Brother Mentor to him.
- Large Ham: Phantom Renegade and Space-Medafighter X.
- Late-Arrival Spoiler: Yes, Henry/Hikaru is the Phantom Renegade, and yes, he's also Space Medafighter X. It has a massive plot significance, but they don't even try to hide it from the viewers.
- Man of a Thousand Voices: Henry/Hikaru does this when he's either The Phantom Renegade of Space Medafighter X. To elaborate, As the Phantom Renegade, Henry uses a rough and gruff sounding voice, while as Space Medafighter X, he uses a more heroic voice.
- Obfuscating Stupidity: He often uses this when he is performing his Big Brother Mentor role with Ikki and his friends.
- One of the Kids: Despite being in his late-teens, he is seen spending most of his time with Ikki and his friends at the Hopmart, and acts like someone of their age.
- Paper-Thin Disguise: Both his Renegade and X personalities. As he still has a recognizable Idiot Hair, and his real personality slips through the cracks. This is exaggerately parodied under his X persona, though — he uses a similar mask as the Renegade, and no one was able to make the connection until The Un Reveal.
- Phantom Thief: Phantom Renegade. His Japanese name is, technically, Kaitou Retort, "Phantom Thief/Bandit" Retort.
- Punny Name: Phantom Renegade's original name, Kaitou Retort. Kaitou (怪盗) is the Japanese word for a mysterious Phantom Thief. On the other hand, Kaitou (回答) is also a Japanese word meaning reply, answer, or retort.
- Scarf Of Asskicking: Space Medafighter X wears one as part of his outfit, as it is a Shout-Out to Kamen Rider.
- Voiced by: Maaya Sakamoto (JP), Ashley Taylor (EN), Rocío Mallo & Rebecca Aponte (LA), Cristina Yuste (SP)
An extremely kindhearted girl who attends Rosewood Academy with her childhood friend Koji. Koji and Ikki constantly vie for her affection.
- Badass on Paper: She's considered a Legendary Metafighter in her home town. Technically, she is undefeated, but only because she's so sweet that no one is willing to go all against her. Plus her legions of fans would stomp anyone who gets too rough with her.
- Cloud Cuckoolander: Karin can be apparently completely disconnected from all the shenanigans around her and yet have moments where she's vastly more competent than the sum of her fellows. Also, if you ever need to pull off a heist, she's your girl.
- Crazy-Prepared: Karin can be a nice little adorable girl, but she's always ready if you need to climb a wall, cross a bridge taken by a bully or even blow up a security door.
- The Ditz: She gives off the impression that she's kind of dull, but she's just a little absent-minded and oblivious to the world around her.
- Dude Magnet: It's not only Ikki and Kouji who have a crush on her; all the boys at her school like her because of her kindness and her cuteness. In the original game they even sell pictures of her!
- Extreme Doormat: When she first meets Ikki, he thinks she's being bullied by her classmates for being poor. She's actually just extremely good-natured, and her classmates like to take advantage of her.
- Girlish Pigtails: Her signature hairstyle, but don't let it fool you.
- Ill Girl: In one of the games' manuals, Karin is stated to have a heart condition where she would die or at least go into critical condition if her heart rate gets too high, which is one of the reasons why Kouji acts like a Jerkass with Ikki in Medarot 2.
- Mistaken for Servant: When Ikki first saw Karin cleaning at her school and mentioning about going to clean a toilet (the latter being a dub-only thing) and recalling how earlier she tried to pick up a 1 yen coin from the bottom of the lake he assumed she was poor and needed to do menial work to pay for tuition. Turns out, she actually likes doing the chores.
- Nice Girl: She is a kind, sweet and polite girl.
- The Nicknamer: Subtle, but aside of calling her Medabot "Nurse-chan" on occasion, she also calls Smilodonad "Nad-chan" in one episode and Rintarou "Rin-chan" in another.
- Oblivious to Love: Karin is oblivious to both Ikki and Kouji's feelings for her.
- The Ojou: Karin is a rich girl who is probably one of the sweetest you will ever know.
- Spoiled Sweet: She may be rich, but she is also very nice and humble with other kids and people. One of many reasons her classmates love her.
A hyperactive kid who idolizes Space Medafighter X. He uses a KBT-Type like Ikki does.
- Anime Hair: His Non-Standard Character Design's signature, since he is a Canon Immigrant to the anime.
- Canon Immigrant: Rintarou is actually the protagonist of his own manga series, Medarotter Rintarou, which was published around the same time as the anime was on air.
- Irritation Is the Sincerest Form of Flattery: Double Subverted. Rintarou causes a lot of trouble when he first shows up, and it all gets blamed on Ikki because they use the same type of Medabot. When Ikki shows up, he assumes that Rintarou is using a KBT type because he's a fan, but he's just a troublemaker who just happens to use a newer KBT-type. Then it turns out that he's actually a fan of Hikaru Agata, who used a KBT-type back in the day. If anything, Hikaru is even more annoyed by Rintarou than Ikki was.
- Keet: Rintarou is a one-man stampede — he is small, can be cute, colorful, and he is also extremely hyperactive.
- Loony Fan: He keeps insisting that he's Space Medafighter X's apprentice any time he shows up. It bugs the crap out of Space Medafighter X, partially because Rintarou has nothing good to say about his Superpowered Alter Ego.
- Older Than They Look: He's slightly older than Ikki and Koji. You'd be forgiven for thinking he's five years old.
- Verbal Tic: In the original Japanese dub he ends his sentences with "-da ze!" or, on rare occasions, with "-ze!".
- Voiced by: Masami Suzuki (JP), Susan Laney Dalton (EN), Giannina Jurado (LA), Yolanda Mateos (SP)
The leader of the Screws Gang. She's hot-headed and aggressive, and a half-decent Medafighter, but rarely poses a threat to Ikki.
- Abhorrent Admirer: She is this both to Kouji and Kawanakajima/Nathan.
- Affectionate Nickname: In the original Japanese, her mother calls her "Hime-chan".
- Didn't Think This Through: She has a collective case of this with her gangmates during the first tournament arc, where they equip Peppercat with powerful parts...that are from heavier, larger Medabots. The Fragile Speedster Peppercat is weighed down to the point of immobility and ends up ringed out by her opponent with a single tap.
- Dub Name Change: From Kikuhime to "Samantha".
- One of the Boys: She spends her time with boys, mostly with the other members of the Screws... which brings her problems when she gets into normal girly things (like falling in love) since she isn't used to dealing with them.
- Starter Villain: She's pretty intimidating when Ikki doesn't have a Medabot. Afterwards, she's pretty much a joke.
- Tomboy with a Girly Streak: Practices ballet, of all things. She also was considering entering a "Miss Medafighter" beauty contest in one episode.
- Tomboyish Name: Applied in both English and Japanese versions, as Samantha (which can be shortened into the more masculine "Sam") and Kikuhime ("hime" meaning princess).
- Tomboyish Ponytail
- Tsundere: She has a heavy tsuntsun mood, who rarely shows her dere side.
- Voiced by: Shigenori Yamazaki (JP), Robert Tinkler (EN), José Méndez (LA), Miguel Ángel Garzón (SP)
The Screws' second-in-command. A wimp and a crybaby, he's completely dependent on his friends.
- Adaptational Wimp: Iwanoi/Spyke in the games is actually a competent Medafighter and the Screws' Techno Wizard. Compare that to his Butt-Monkey status in the anime.
- Aesop Amnesia: He takes Ikki's advice about using close-range combat exactly once. He seems to just prefer using a shooter-type.
- Butt-Monkey: Iwanoi is the butt of all jokes, mostly since he isn't a good (he was ranked in the last places of the National Ranking) nor a smart medafighter.
- Dub Name Change: From Iwanoi to "Spyke".
- Friendly Enemy: He is probably the only one of the Screws who is more friendly with Ikki and Arika, on occasion.
- Idiot Ball: Takes hold of it and never lets it go. He gets told bluntly that his troubles could be fixed by either changing Cyandog's medal or putting the medal in a close combat type body. He doesn't want to change the medal because that's basically his friend's brain. Fair enough...but when he goes and buys a new body, instead of buying the right type which would instantly improve his battle prowess to not pathetic levels, he buys 'another' shooting type with the exact same problem.
- Nice Guy: He's very friendly compared to his friends, and he devotedly pampers his Medabot. If only he wasn't so pathetic.
- Straw Loser: He exists just so the Screws look slightly more intimidating by comparison.
- Techno Wizard: His game incarnation.
- Throw the Dog a Bone: In "Future's Past", it's his turn to step in for Space Medafighter X in the tournament, and it's immediately clear that the rest of Team Japan is worried about how he'll negatively affect them, especially after Patra (the leader of Team Egypt, who they'll be facing next) points out that Team Japan has a specific weak link that everyone assumes is him. However, during the fight, Patra reveals that it's Koji (who had been extremely hard on Spyke during training and careless about Krosserdog's well-being during the battle out of worry that they would screw things up) who was the weak link (due to him relying on the same, easy-to-counter strategies in battle, whereas Space Medafighter X switches Medabots every fight for variety and Ikki has the power of the Medaforce for Metabee to utilize). Realizing this breaks Koji's spirit, and he is unable to tell Sumilidon to get out of the way when Team Egypt comes in for the finishing blow. It ends up being Krosserdog who saves Sumilidon at the last second, taking the hit and bringing down the two T-Mummies with it, allowing Metabee to finish off Cleobattler. It's enough to evoke a great swell of pride from the other Screws.Samantha: (nodding with her arms folded) I never doubted you for a second, Spyke.Sloan: (tears streaming down his face) I love happy endings.
- Willfully Weak: He could easily improve his fortunes by either replacing his medal or Medabot body, but he prefers using what he's got.
- Voiced by: Yoshiko Iseki (JP), Darren Frost (EN), Elena Díaz Toledo (LA), Ricardo Escobar (SP)
The last member of the Screws. He doesn't say much, but has quite a bit of presence.
- The Big Guy: Of the Screws. In the games, he can carry rocks to block your path like it's nothing.
- Crouching Moron, Hidden Badass: He looks and acts like a dullard, but he's actually a very dangerous opponent.
- Dub Name Change: From Kagamiyama to "Sloan".
- Eyes Always Shut
- Flat Character: He's got little personality, other than his devotion to Samantha. This is actually a carry-over from the games, where his only personality trait was his obsession with laundry.
- The Stoic: He is rarely seen with any other expression that isn't his default. He's not the most talkative of the Screws either.
- You Are Better Than You Think You Are: He's a decent Medafighter, but he doesn't have much confidence in his abilities. Once Samantha gives him a pep-talk, he annihilates the Mexican national team.
Baron Von Banish
The man behind the Screws. He seems a little too intense to be leading a primary school gang, but it's all a facade.
- Anti-Climax Boss: Invoked with him and his Medabot, Bankaran/Banisher, who through the episode they appear are made up to be fearsome opponents. The actual robattle ends as soon as Metabee shoots Banisher. Once. (His special ability is having a Strong Appearance). In the games, Banisher could only deal damage by counterattacking, and since Metabee headshot it (and Metabee is deceptively strong), he presumably dealt enough damage to knock him out. (Either that or the robot is just too weak to fight, and Baron instead tries to scare opponents into submission.)
- Paper Tiger: Much like his Medabot, he's a huge wimp with an intimidating appearance.
- Voiced by: Junko Takeuchi (JP), Joseph Motiki (EN), Luis Miguel Pérez (LA), Francisco Javier García Sáenz (SP)
Ikki's no-nonsense Medabot. Thanks to an unique medal, he has a fiercely independent personality and is much stronger than his outdated design would suggest. He and Ikki constantly butt heads, but he really does care for his Medafighter deep down.
- Angrish: In the English dub at least, his speech is generally accompanied by the "Ki!Ki!Ki!" noise he makes when excited or under stress.
- Angry Black Man: Metabee is played as one in the dub by Joseph Motiki.
- Berserk Button: Do NOT call him defective nor a piece of crap.
- Finishing Move: Metabee's Reaction Missiles, replaced halfway through the series by the Medaforce when they become So Last Season.
- Hair-Trigger Temper: Uh-huh. He gets annoyed very easily.
- Heroic Sacrifice: Pulls one to destroy Babbyblu, though he gets revived by aliens not long after.
- Jive Turkey: He peppers his speech with early 90s hip-hop slang, as part of his Angry Black Man persona. And it's hilarious.
- One-Liner: At least in the dub, he is the one who does them the most."Kiss your bot goodbye!"
- Simple, yet Awesome: Metabee is an old, malfunctioning, outdated model armed with very simplistic weaponry (machine guns and rockets) going up against machines that can do all sorts of things from manipulating gravity to firing giant lasers, but can still kick ass like nobody's business. Admittedly, part of it is probably due to having a unique medal.
- Wave Motion Gun: When he uses the Medaforce.
Arika/Erika's Medarot partner. A friendly Sailor-Multi type who helps her Master with her journalist adventures.
- Affectionate Nickname: "Brass", given by her medafighter, Arika. The actual name of the model Brass belongs to is Sailor-Multi.
- Awesomeness by Analysis: She doesn't have much firepower, but her scanner makes her shots a lot more effective.
- The Chick: She's a mediocre combatant at best, and she doesn't fight very often.
- Jack-of-All-Stats: Though she lacks Metabee's rocket launchers, she is just as tough and agile, and possibly even more precise.
- Sailor Fuku: It's built into her design.
- Ship Tease: With Metabee.
A roaming Medabot without a Medafighter. Quiet and solitary, Rokusho avoids fighting just for the sake of it. He searches for clues to his lost memories.
- All-Encompassing Mantle: His garment of choice, meant to make him look like a Ronin. Notable, since Medabots don't tend to wear clothes at all.
- Aloof Ally: He roams around pursuing his own agenda, and won't even give up his name when he first meets Ikki and Metabee. He warms up to them eventually, but still only helps them out if he happens to be passing through.
- Badass Baritone: As provided in the dub by the late great Mark Dailey (best known as the "Voice" of Toronto's Citytv in the 80s and 90s).
- But Now I Must Go: He leaves towards the end of Season 1 to search for Dr. Hushi. It causes some inconsistencies with the dub episode order, since he shows up in some episodes after he's left and before he returns.
- Dark and Troubled Past: Long ago, Rokusho once had a happy life with his creator, Professor Hushi and Baton, the Robot Parrot. Unfortunately, one day, his home was suddenly caught on fire. Which was revealed to have been caused by Dr. Hebereke/Meta-Evil. Because of this, Rokusho was left without a home, and was forced to wander the Earth. He got better, though.
- Do Androids Dream?: Rokusho is a special Medabot, with dreams, complex emotions, and amnesia.
- Foil: To Metabee. Both are independent beetle-types with rare medals, but have polar opposite personalities and fighting styles.
- Martial Pacifist: Unlike most Medabots, he doesn't like to fight unless he has a really good reason. When he does have a reason, he's quite a challenging opponent.
- Misplaced Retribution: Almost killed Dr. Aki when he wrongly learnt that he was responsible for the house fire.
- The Stoic: He is mostly seen as such, but with a mentor-like twist. However, when his friend Baton falsely says that Dr. Aki killed his old master (and when Rokusho later learns Baton was reprogrammed to falsely accuse Aki)... he becomes the Not So Stoic.
- Super Prototype: He's one of the first — if not the first — Medabots ever made, and is one of the strongest and most advanced. He even comes with a rare medal.
Kouji's Medabot partner.
- Attack Reflector: His Disrupter, which not only nullifies long ranged weapons, but can send Metabee's seeker missiles back to the sender.
- Badass Normal: Manages to be about on par with Metabee despite not having a rare medal.
- Empowered Badass Normal: He gains the ability to use the Medaforce in Season 2, despite not having a rare medal.
- Close-Range Combatant: He uses a sword and a punch, with no long ranged weapons.
- Flat Character: He doesn't really have much of a personality.
- Foil: To Metabee. While Medabee is a fiercely independent shooter-type with a rare medal, Sumilidon is a relatively normal grappler-type who is dutifully obedient to Koji.
- Lightning Bruiser: Extremely fast and agile, but also a heavyweight when it comes to raw power.
- Panthera Awesome: A Sabertooth Tiger type
- The Southpaw: His main weapon, the Flexor Sword, is on his left arm.
Karin's Medabot partner. She's a Medabot who specializes in healing and protecting herself or other Medabots from harm.
- Affectionate Nickname: In the original Japanese, Karin sometimes refers to her as "Nurse-chan".
- Barrier Warrior: The only thing she can do besides heal is use an invincible barrier. It's strong enough to take several hits from the Giant Emperor/Giganko.
- Dub Name Change: From Saintnurse to "Neutranurse"
- Healing Factor: Theoretically, she can use her healing ability on herself. For some reason, she never really does.
- Healing Hands: She can heal just about any level of damage to a Medabot short of complete destructon. In the anime, she apparently can even heal/calm humans!
Kikuhime/Samantha's Medabot Partner.
- Cat Girl: Peppercat's Medabot model armor and personality is based on a female cat.
- Fragile Speedster: Of the Screws' Medabots, she's by far the fastest, and her attack power is somewhere between Cyandog and Totalizer. However, Ikki points out that the only reason she's so fast is because Samantha deliberately removed parts of her armor, making her much faster but unable to take hits. As a result, while she can deal it out very well, she can't take more than a few decent hits before her medal ejects
- Shock and Awe: Her source of power is electricity, and she often takes advantage of the situation as she needs it.
Cyandog (later Bluesdog/Krosserdog)
Iwanoi/Spyke's Medabot partner.
- Animal Jingoism: His dog-type body is incompatible with his monkey-type medal, referencing an old Japanese idiom about "fighting like dogs and monkeys."
- Butt-Monkey: Just Like his Medafighter Spike, Cyandog has the same level of bad luck. Which is justified because Cyandog is powered by a monkey medal.
- Long-Range Fighter: Cyandog's speciality is this but since he has a monkey medal inserted, he cannot take advantage of it because monkey medals specialize in hand to hand combat. As Krosserdog, however, his more accurate Medaparts are able to somewhat mitigate the incompatible medal.
- Mid-Season Upgrade: He gets and upgrade to the superior Krosserdog model partway through Season 2.
- Unskilled, but Strong: He's actually a decent Medabot, one of the more advanced models in the series. But his Medafighter is not all that great, and his body and medal are incompatible.
Kagamiyama/Sloan's Medabot partner.
- Dub Name Change
- Mighty Glacier: He's extremely slow, but his attack power is monstrous. Figures, considering it's a tortoise.
- Spell My Name with an "S": Is it Kiethturtle or Keithturtle?
- Turtle Power: Tortoise-based Medabot with tons of power behind it. Too bad he's often Out of Focus.
- Wave Motion Gun: Its laser cannon doesn't hit very often, but when it does, it's pretty much a One-Hit Kill.
The Medabot used by Space Medafighter X. He's a highly modified KBT-Type, much stronger than the commercial variety. He's also the original Metabee used in the World Championship 12 years ago, who stared the Ten Days of Darkness. His medal was damaged, and so he has no memory of the event.
- Ace Custom: In the anime, Arc-Beetle is one of the strongest Medabots in the world and has never lost a single Robattle. It should be noted that Arc-Beetle is powered by a rare medal and his Medafighter is Space-Medafighter X/Phantom Renegade aka Hikaru/Henry Agata.
- Canon Immigrant: Arc-Beetle originally appeared in the Medarot R manga as a upgrade for Kantaroth. It's later included in the subsequent games.
- Charged Attack: His head part, the Prominence. It takes a couple of seconds to charge, but is absolutely devastating when it hits.
- Identity Amnesia: Arc-Beetle is actually Henry's old Metabee, whose medal was destroyed to stop the "Ten Days of Darkness". While the medal was repaired, his memories and old identity never came back.
- Minor Major Character: Aside from being the Medabot who caused the "Ten Days of Darkness", he is Space-Medafighter x/Phantom Renegade's Medabot, which should get him at least as much spotlight as his partner. However, he barely fights any battles, is not even clearly seen until much after being introduced, and has no real personality or lines (the last point, admittedly, because his old identity was erased).
- Playing with Fire: Its Medaparts all shoot fireballs, even its feet. The odd one out is the head part.
- The Power of the Sun: His Prominence is a solar-powered Wave Motion Gun.
- The Quiet One: Has literally one line in the entire series.
- Superior Successor: A massively superior version of the KBT-series.
- The Atoner: He has a massive guilt complex because he turned on Victor and destroyed his village during the Ten Days of Darkness. He finally makes it up to Victor by sacrificing himself to save his life.
- Extreme Doormat: He takes all of Victor's abuse without comment because he feels like he deserves it and is desperate for Victor to trust him again.
- Heroic Sacrifice: Destroys his body to save Victor from one of Meta-Evil's attack medabots, though his medal survives the explosion.
- Lightning Bruiser: He has slightly more power than Sumilidon at the expense of slightly less speed. They're both so fast that it's hard to tell the difference.
- Long-Range Fighter: He's Sumilldon's counterpart in the same way Metabee is Rokusho's: both are lion types, but while Sumillidon is a hand-to-hand combatant, Warbandit is a shooter.
- Panthera Awesome: A Lion type medabot.
- The Stoic: Shows little to no emotion just like his Medafighter. But just like Victor, its a facade to cope with their shared Dark and Troubled Past.
Rintarou's Medabot partner.
- Canon Immigrant: He and Rintarou come from the Medarotter Rintarou manga, which was published around the same time as the anime was on air.
- Oddball Doppelgänger: He's a newer model in Metabee's series with a more angular design and a more subdued version of Metabee's personality.
- Spell My Name with an "S": Is it Kantaros or Kantaroth?
Dr. Hebereke/Dr. Meta-Evil
The true mastermind behind the Roborobo Gang. Dr. Hebereke claims to be a descendant of the ancient race of the Medalians. He wants to restore said ancient civilization and make Medarots rule the Earth once again.
- Actually a Doombot: The Meta-Evil that shows up in episode 25 is a robotic duplicate.
- Bad Boss: If you fail him, you'll get turned into a Teddy Bear.
- Big Bad
- Cyborg: Explicitly refers to himself as one.
- Dirty Old Man: His 2 Core incarnation. His first motivation for his world domination plans is to become a rich playboy and pick up girls, *then* his revenge against Dr.Aki. Searching one particular computer in the Fiyun Fortress will reveal his most recent search query was "Top 10 Music Idols" and "How to pick up girls".Ikki: (With a disappointed look)"Dr.Armond..."
- Dub Name Change
- The Faceless: For the majority of the anime, he is seen only from below the neck area before the reveal.
- Knight Templar: Determined to return Medabot civilization to its former glory, despite the Medabots not wanting to rule the Earth.
- Mad Scientist: He is the mind behind the Roborobo Gang, and he is obsessed with power. He strongly believes that he must return the Earth to the glorious old times where the Medabots (as an ancient alien race) ruled it, no matter how many lives that would take.
- Manipulative Bastard: He altered Baton's memory so he would say Dr. Aki was the one who initiated the fire that "killed" Dr. Hushi when in reality it was Dr. Hebereke himself who did so. As a result, Rokusho almost killed Dr. Aki in revenge.
- Villainous Breakdown: He starts losing it when the medabots of Japan send Metabee their energy, and completely breaks down when Hushi shows up.
The leader of the Roborobo/Rubber-Robo Gang... Except he is not, as it turns out, the real leader of the Gang is Dr. Hebereke.
- Butt-Monkey: In comparison to his comrades, Seaslug suffers from this the most. From being tranquilized by a Medabot in space to being turned into a Teddy Bear.
- Idiot Hair: He sports a cowlick that even comes out from his rubbersuit.
- Japanese Delinquents: He used to be a delinquent when he was young. Or so he claims.
- Only Known by Their Nickname: In the original Japanese, his real name is revealed to be Sakenosuke Kasukabe, from which his nickname is derived (SAKEnosuke KASUkabe). The English dub follows this trend since his actual name is revealed to be SEAmore SLUGbottoms
- The Mole: He infiltrates into the Medabot Corporation using the identity of "Mr. Narazuke" (Mr. Tunahead in the dub) once he is degraded from his leader of the Rubber-Robo gang role.
- Evil Genius: Despite his age, he is incredibly smart. Too bad he uses his intelligence for evil, huh?
- Only Known by Their Nickname: In the original Japanese, his real name is revealed to be Mitsuo Sara, from which his nickname is derived (SARA MItsuo). The English dub follows this trend since his actual name is revealed to be SHRIMPy LIPpowitz
- You Are in Command Now: Dr. Meta-Evil puts him in charge of the Rubber-Robo Gang after getting tired of Seaslug's many failures.
- Dark Chick: The only female member of the gang.
- Only Known by Their Nickname: As it seems to be a rule of the Roborobo Gang for their members to have aliases... In the original Japanese, her real name is revealed to be Rumi Takasu, from which her nickname is derived (TakaSU RUMI). The English dub follows this trend since her actual name is revealed to be GILda GIRLnikova
- Qipao: When in her civillian identity, she wears a sleeveless one.
- Verbal Tic: In the original Japanese, when she is not using her rubbersuit (as per the usual "robo" verbal tic), aside of changing the tone of her voice, she slips into a verbal tic that consists of adding "-tte kanji" to her sentences.
The President of Medabot Corporation.
- Big Good
- Cool Old Guy: Or so he thinks of himself, as he is clearly under the impression that he is at least as cool as everyone thinks he is.
- Crazy-Prepared: Built a giant Metabee just in case Dr. Meta-Evil decided to use a Humongous Mecha to destroy humanity. He also had a safety switch implanted in all medabots in case there was a repeat of the Ten Days of Darkness, but never got to use it.
- I Was Quite the Looker: In a flashback from episode 26, you can see a young Dr. Aki observing the Rare Medals with his teacher, Professor Hushi.
- Obfuscating Stupidity: Deep inside, Dr. Aki knows more than he seems to tell the others.
- Self-Made Man: Dr. Aki sold patents of some Medabot models to other companies to have the money to start Medabot Corporation.
- Trademark Favorite Food: He likes pudding, and he invites Ikki and the others (from Henry's own money) to eat them with him.
The leader of Team Kenya. His Medarot partner (though he doesn't acknowledge him as his friend as to call him "partner"... at least not at first) is Warbandit.
- Bald of Awesome: Mixed with Bald of Evil.
- Cavalier Competitor: He does not take robattling or the World Tournament seriously at all, and mocks Ikki endlessly for doing so.
- Combat Pragmatist: Victor is not above using his teammates' Medabots as sacrifices to either take out an enemy Medabot or protect Warbandit (not that he cares for Warbandit itself, he just wants the victory).
- Dark and Troubled Past: Let's see... His hometown got destroyed by rampaging Medabots during the Ten Days of Darkness, his family most likely got killed (he certainly never saw them again)... Guess what? All those traumatic experiences didn't do any good to his personality.
- Jerkass with a Heart of Gold: He is a cynical medafighter who sees Medabots (his partner Warbandit, included) as mere tools. He is also working for the Big Bad seeking vengeance for the "Ten Days of Darkness", which destroyed his home village and killed all his family, back in Kenya. His attitude only changes until Warbandit sacrifices himself as a way to protect him; only then he shows his true feelings.
- Only in It for the Money: He hates Medabots and doesn't enjoy robattling at all...but he's excellent at it, and doesn't have any other skills to speak of. For him, it's a job and nothing else.
- Punch-Clock Villain: He really doesn't like taking other people's medals, but he does it because the rules of the World Tournament allow him to, and his employers are paying him to do it. When he finds out that his employers are the Rubberobo Gang, and that they plan to use the medals to start another Ten Days of Darkness, he immediately withdraws his allegiance.
- The Stoic: Victor is rarely seen without a frown on his face, or with a less cynical view about what a Medabot is supposed to be for the humans.
Dr. Aki's granddaughter.
- Suspiciously Similar Substitute: Pulled more specifically on Spirits/Damashii, Nae serves as Karin, Dr. Aki, and Henry's replacement. She's Dr. Aki's granddaughter (as opposed to his niece), becomes Ikki's older Oblivious Love Interest, provides Metabee with upgrades and plays Cool Big Sis. An aversion in the videogames, since Nae Akihabara is introduced to the player as an intern working in the Medarot Corporation in the first game, she then becomes regular in the next games.
- Wrench Wench: Her truck even functions as a portable mechanic shop.
Mr. Uruchi/Mr. Referee
The self-proclaimed Robattle Referee.
- Authority Equals Asskicking: The one time Mr. Referee is attacked, he strikes back with a Medabot satellite.
- Berserk Button: Just don't break the rules of Robattles.
- Beware the Nice Ones: As mentioned above, if you dare to break the rules of the Robattle Association, you'll regret it.
- Combat Referee: Taken up to Determinator levels; he will show up to officiate your Robattle, even if it means riding a giant kite to a battle taking place on top of a burning building.
- Cool Old Guy: And how. Despite his age, he manages to be wherever the main characters are to officiate a robattle. He also can show his mandatory power of respect as an authority figure (a referee in this case) to medafighters who may be doing anything against the rules of the Robattle Association.
- Made of Iron: He can take more of a beating than any Medabot.
Ms. Karasumi/Ms. Caviar
A scientist working at Medabot Corporation.
- Dating Catwoman: A flipped aversion. Ms. Karasumi falls in love with "Mr. Narazuke/Tunahead" (Sakekaasu/Seaslug in disguise), at the moment he infiltrates the Medabot corporation and eventually, reveals his true intentions. She tries for all the possible ways to get to him (even filling the Space Medafighter X role at the final tournament). At the end, however, her long-lost lover just accepts her (after the Roborobo Gang parted their own ways, except for him), making her a new member of the gang.
- Meganekko: Ms. Caviar is an unbelievably sweet and smart bespectacled woman who falls in love with the wrong man.
- The Worf Effect: She uses a Belzelga in the final rounds of the World Tournament, a Medabot that debuted by tearing apart an army of tanks. She's the first to be taken out.
- Comically Missing the Point: His last pep-talk to get Ikki to fight the Giant Emperor: "help your loved ones and give them the gift that only you can give." Ikki takes it to mean that he shouldn't give up and runs off, with the salesman confusedly thinking that he had finally made a sale.
- Intrepid Merchant: He shows up everywhere, even in the Rubberobos' hideout and the site of world-destroying Medabots. It doesn't help him sell, but you have to admire his tenacity.
- Lennon Specs
- Mistaken for Profound: Is he ever. Most of the times, his seemingly-profound advice is actually meant to convince Ikki to buy a chick. Sometimes he does give useful inspirational words on purpose, though.
- No Name Given: Not that he's significant enough to merit a name.
- Severely Specialized Store: He only sells chickens...at least until the end of Season 1, where he's sold all of his stock to The Colonel. Then he sells rabbits. He himself points out that this isn't a great business model, and that pet stores have put him out of business countless times.
- Arch-Enemy: He treats Team Japan this way, because he was "betrayed" by the former Japanese champion. He also treats Space Medafighter X this way, because he is said champion. He gets better, though.
- But Not Too Black: He's supposed to be a Native American, but is a freckle-faced Significant Green-Eyed Redhead.
- Jerk with a Heart of Gold: He's a little arrogant and treats Team Japan like crap, but he's a Nice Guy who refuses to take the medals of opponents he defeats.
- Loophole Abuse: He invented technology that allows him to transport his Medabot while in use. It's technically not a foul, because the technology is too new for there to be a rule against it.
- We Used to Be Friends: With the former Japanese champion, but now hates him because he allegedly started the Ten Days of Darkness.
The leader of Team Egypt. Her Medarot partner is Empresspatra/Cleobattler.
- Break Them by Talking: She does this to Koji by convincing him that he's Team Japan's weak link. It's brutally effective, and it takes him two episodes to snap out of it.
- Confusion Fu: Her Cleobattler is a morph-type that can change its Medaparts to anything else mid-battle.
- Jerk with a Heart of Gold: She's incredibly nice to everyone who isn't team Japan.
- Manipulative Bastard: Patra specializes in psychological combat, using her Medabot's changing parts to throw the opponent off-balance and getting inside her opponents' heads.
- Mirror Match: When she fights Ikki one-on-one, she uses Cleobattler's morph ability to try this tactic.
- We Used to Be Friends: With former Japanese champion Hikaru Agata, but now hates him because he allegedly started the Ten Days of Darkness.
The leader of Team Iceland. His Medarot partner is MarineKiller/Orkamar.
- Cloud Cuckoo Lander: Well, he is rather eccentric. For example, he likes to look up for hot springs, believes in aliens (he tells Arika that he wants to robattle one... though to be fair, said belief wasn't so out of this world as the series finale proves) and all in all his personality seems to be that of an adorable airhead (kinda like Karin's.)
- Nice Guy: He is a kind guy, probably the kindest that Arika has met (compared to Ikki, at least).
- Ship Tease: With Arika oh so very much, and they managed to do this on just two episodes! It is quite obvious that Arika develops a crush on him but Belmont's feelings towards her are quite vague, though he definitely develops a soft spot for her.
- Spell My Name with an "S": Is it Belmont or Bermot?
Hikaru's childhood friend. Her Medarot partner is Allumi, a Sailormate model. Much like his friend Hikaru, she also takes a secret identity: the Phantom Lady.
- Adapted Out: She did not appear in any of the two seasons of the anime despite being quite an important character in the games.
Professor Fushihara/Dr. Hushi
A brilliant scientist who developed the Medal Theory. The creation of all Medabots is based on his work.
- A Pupil of Mine, Until He Turned to Evil: Dr. Armand/Meta-Evil was once his apprentice until he wanted to use his inventions to take over the world. It's not entirely clear if Armand was corrupted by the potential of Medabots or was a Deceptive Disciple the whole time, though the former is implied more.
- Dub Name Change
- He's Just Hiding!: Rokusho suspects that the fire that destroyed the lab didn't really kill him, and he sets off to find him. He's right.
- Lost Technology: Rokusho discovers that he did not invent Medabots, he merely rediscovered the technology from an ancient civilization.
- Mentor Archetype: To Dr. Aki and Rokusho, complete with...
- Mentor Occupational Hazard: Killed by Dr.Meta-Evil in an attempt to keep his research from falling into the wrong hands.
- One-Man Industrial Revolution: The 22nd Century seems to be almost identical to the early 21st in terms of technology...except for the fruits of Dr. Hushi's work.
- Posthumous Character: He's long dead by the time the series starts, but he plays a significant role in Rokusho's and Dr. Aki's backstories. Not to mention, he's the entire reason that the show has a premise. He makes an appearance in the finale of the second season.
- The Professor: His exact title depends on the adaptation, but he fits this archetype the best.
- Reluctant Mad Scientist: He was enthusiastic about his work until Dr. Meta-Evil wanted to use it for evil purposes. He tried unsuccessfully to destroy all of his research out of a fear that it would be misused.
- Talking the Monster to Death: Does this to Meta-Evil, telling him that the former Medabot civilization wiped themselves out.
Professor Hushi's pet parrot, and long time friend of Rokusho.
- Robotic Reveal: After his apparent "Death", Mrs. Tenryou picked Baton up and saw that his batteries had run out.
- Spell My Name with an "S": Is it Burton or Baton?
Ikki's pet dog.
