Voiced By: Toshiyuki Morikawa (Japanese), Bob Bergen (English), Jorge Roig Jr. (Latin American Spanish)
The main character of the show. Takaya is the 2nd son of the Aiba family and was captured along with them by the Radam and set to become a full Tekkaman until his father saved him and had him launched to Earth. The incomplete biological engineering allowed him to transform into a being hell-bent on the Radam's destruction, the titular Tekkaman Blade. With his memories not actually lost to him, he joined the Space Knights to defeat the Radam (getting the nickname D-Boy) and ultimately succeeds, but not without great sacrifice. Eventually however, the bonds he made with the Space Knights heal his trauma and he begins assisting his girlfriend Aki in training a new generation of good Tekkamen.

Miyuki Aiba/Tekkaman Rapier/Shara Carter
D-Boy's sister and the youngest member of his family, Miyuki was part of the Argos crew. She has a very close relationship to her brother.

Aki Kisaragi/Star Summers
Voiced By: Megumi Hayashibara (Japanese), Barbara Goodson (English), Rossy Aguirre (Latin American Spanish)
Aki is a member of the Space Knights and the co-pilot of the spaceship Blue Earth.
- Action Girl: Is skilled in hand-to-hand combat, an excellent pilot and pretty handy with a gun.
- Badass Adorable: Overlaps with Badass Normal; she might be The Chick, but early on the series she is said to be the physically strongest of the Space Knights, with the exception of D-Boy, so much that she's confident enough to challenge D-Boy to spar with her after throwing a guy larger than her.
- Beware the Nice Ones: She punched D-Boy in the face after he snarked at her attempt to make him eat something and would have shot a wounded Shinya if D-Boy hadn't stopped her.
- Brainy Brunette: Certainly qualifies in both intelligence and common sense. Aside her physical skills (combat, piloting) she is also responsible for the collection and analysis of Radam data.

- Remember That You Trust Me: To D-Boy.
- Roaring Rampage of Rescue: When D-Boy is taken by the military.

Noal Vereuse/Ringo Richards
Voiced By: Yasunori Matsumoto (Japanese), Kerrigan Mahan (English), Carlos Iñigo (Latin American Spanish)
A member of the Space Knights, Noal is a laid-back, flirty young man who abandoned a career in the military in order to fulfill his dream of being a pilot. Initially antagonistic towards D-Boy, he ends up becoming one of his most loyal companions. He's a bit of a card shark and a gambler, and tends to be a bit overconfident and hot-tempered at times.
- Ace Pilot
- The Charmer: Handsome, adventurous and very competent in what he does.
- Chivalrous Pervert: Has hints of it, especially towards Aki.

Miletta 'Milly' Le Rouge/Tina Corman
Voiced By: Chisa Yokoyama (Japanese), Julie Maddalena (English), Ana María Grey (Latin American Spanish)
Chief communications officer for the Space Knights, she is only 16 and can at times act rather childishly - yet at other times may see things more clearly than anybody else.
- Communications Officer: Chief of Communications, at sixteen!
- Like Brother and Sister: With D-Boy (she reminds him of his younger sister).
- Mood Whiplash: Having such a cheerful child in a middle of a Crapsack World that is filled by adults feels really inappropriate. Levin kinda lampshades it early on in the series.
- Tagalong Kid
- You Remind Me of X: Her similarity with D-Boys' sister is one of the reason that she's the first person that can talk casually with D-Boy
Heinrich von Freeman/Commander Jameson
Voiced By: Hirotaka Suzuoki (Japanese), Michael Forest (English), Humberto Vélez (Latin American Spanish)
Formerly the assistant of General Colbert, Freeman is now the commander and chief of the Space Knights. He uses his intellect, leadership skills and his ability to keep a cool head under pressure to help and protect his team and most importantly, to find a way to turn the tables in humanity's favor in the war against the Radam.
- Big Good: After all, he's the Chief of the Space Knights.
- Commanding Coolness: In the English dub.

- The Leader
- The Stoic
- Tranquil Fury
Voiced By: Shozo Iizuka (Japanese), Richard Epcar (English), Carlos del Campo (Latin American Spanish)
Honda is the man to call when you need something built good and fast. He is Pegas' co-constructor and the Blue Earths' main repair engineer is one of the persons whom the Space Knights rely on to get them off the ground.
- Brave Scot: In the dub, at least.
- Boisterous Bruiser
- Gentle Giant: His dream is to fly a kite after world peace is restored.
- Grease Monkey: Balzac calls him this in the dub.
- Mr. Fixit
- Team Dad: He's essentially one to D-Boy, and to a lesser extent to most of the team.
A 19 year old computer whiz and technophile with a crush on D-Boy. Because of his implied homosexuality/transexuality, his gender was changed to female in the English dub.
- Alliterative Name: In the dub.
- Agent Peacock: In spite of his romanticism and emotional personality, Rebin is more than capable to grab a machine gun and start kicking ass when surrounded by murderous alien monsters. On top of that, his incredible technical skills have contributed to the creation and upgrade of Pegas and to the maintenance of Blue Earth, the only spaceship left capable of going outside the stratosphere.
- Camp Gay: Japanese version.
- She's a Man in Japan: Leading to an unfortunate case of Get Back in the Closet.
- The Engineer
- Tomboy and Girly Girl: Tomboy to Star's Girly Girl in the English dub.

Voiced By: Nobuo Tobita (Japanese), Tom Wyner (English)
Pegas is a robot designed and created by the Space Knights' engineers for the purpose of enabling D-Boy/Blade to transform into a Tekkaman after his crystal shattered. He also serves as a bodyguard, transportation method and battle aid for Blade and the two eventually become friends in spite of Pegas being a robot.
- Heroic Sacrifice: During the final battle with Tekkaman Omega, Pegas protects Blade from what would have been a killing blow and is destroyed in the process. His last words are a farewell to Blade.
- Robot Buddy: He and Blade become friends.
- Single Tear: An unusual example in that Pegas is a robot who displays no emotion over the course of the series... except at the end, when a single oil tear falls from his eye when he says goodbye to Blade.
- Transforming Mecha: He contains shards of Blade's crystal and amplifies them, allowing Blade to transform.
Earth Defence Force
Balzac Asimov / Balzac St. Jacques
Voiced By: Kenyuu Horiuchi (Japanese), Steve Bulen (English), Jorge Ornelas (Latin American Spanish)
Initially a laid-back, easy-going war correspondent out to write a story about Tekkaman Blade, Balzac is soon to be revealed as working for General Colbert as a spy. His mission was to gather as much information about the Tekkaman armor as possible, which he achieves by breaking into Commander Freeman's secret laboratory. Afterwards, he was chosen to pilot the first prototype Sol Tekkaman and while he did well against the regular Radam monsters, he was no match for Tekkaman Evil. After a near death experience following that encounter, Balzac reforms and joins the Space Knights.
- Break the Haughty: After his closest (and only) friend gets killed and he himself nearly dies at the hands of the enemy, Balzac gets thrown off his high horse.
- Call to Agriculture: In the second season; both results in and is the result of Character Development.
- Childhood Friends: With Marlo, his best friend.
- Destined Bystander: For a while.
- Glory Hound: He got better.
- Heroic Sacrifice: In the end, he did one to defeat Tekkaman Sword, thanks to the latter's Taking You with Me
- I Just Want to Be Special
- Jerk Ass: Especially after he becomes the pilot for the man-made Tekka-armor. He is absolutely horrible to Blade.
- Jerk with a Heart of Gold: It just takes a near-death incident and being saved and nursed back to health to bring it out.
- Muggle Power
- My Girl Back Home: Rachel, the woman who found him and nursed him back to health.
- Street Urchin: Used to be one until he got recruited by the army for his skills.
General Colbert/Xerxes Galt
Voiced By: Shinya Ootaki (Japanese), Mike Reynolds (English), Herman López (Latin American Spanish)
A haughty and extremely ruthless man, Colbert is one of the top generals of the Earth Defense Force and a former colleague of Freeman's. From the start, he is very interested in Tekkaman Blade and tries to have him transferred under his control. He later sent a spy to gather information about Tekkaman and used the data to create a Sol Tekkaman suit which proved very efficient against regular Radam, but failed when confronted with a real Tekkaman. During the war he gained access to the Thunderhawk missile, which he planned on using to destroy the Space Ring, regardless of the disastrous results it would bring for the human race, as large chunks of the Space Ring would fall on Earth and level anything in their path. Tekkaman Blade destroys the missile in mid-flight, which wipes out Colbert together with his entire base.
- Armchair Military
- Bald of Evil: He's a complete jerk, even though he's one of Earth's defenders.
- Fantastic Racism: To extremes at time, even treating the hero like a traitor of his own race simply for being a Tekkaman even though he obviously is on the side of humanity.
- General Ripper
- Meaningful Name: Named after the famous king of Persia.
- It Must Be Mine: About Blade.
- The Unfettered: Has shades of this right from the beginning. He will actively work against the Space Knights even though they are on the same (losing) side, and pursues his mad scheme of destroying the Space Ring despite the complete annihilation it would cause. He wants to see the Radam destroyed, but he doesn't care if humanity survives.
- With Us or Against Us: Says this almost verbatim in the English dub.
Kozou Aiba/Ulysses Carter
Voiced By: Mugihito (Japanese)
Patriarch of the Aiba family and head of the Argos exploration expedition. He rescues his second-eldest son from the Radam, launching him in an escape pod to earth, before dying from the after-effects of a failed transformation.
- Abusive Parent: An odd, out of character example, depending on whether one chooses to regard the Burning Clock special as canon. After the Aiba house burns down with Kozou's wife inside, the entire family returns to the charred ruins, where they find her burned-up corpse. For some inexplicable reason, Kozou allows his children to look at it. Shinya is understandably deeply traumatized by the macabre sight, even more so as one of his mother's hands falls off on its own.
- Badass Normal: He is a scholar who managed to become the head of an important space exploration mission, and his marksmanship skills are nothing to scoff at. Add to that the fact that on top of all of this, he managed to raise four children on his own after his wife died and you get a pretty impressive picture.
- Bold Explorer: Embarks together with his entire family on an ambitious voyage to explore space.
- Distinguished Gentleman's Pipe: He received it as a birthday present from his three sons, and declared it to be his most valuable possession.
- Meaningful Name: In the dub, he is named after the legendary king of Ithaca, who underwent a decade long journey at sea.
- Standard '50s Father: What we see of him, anyway.
- The Patriarch
- Unwitting Instigator of Doom: His space expedition attracted the Radam, which led to the deaths of all except one of his crew members and almost caused the extinction of the human race.
Kozou's wife and the mother of the Aiba/Carter children. Already dead by the start of the series, she appears infrequently in Blade's flashbacks.
- The Faceless: In the series. We finally get to see her face in the Burning Clock special.
- Heroic Sacrifice: She dies protecting her young son Shinya from a house fire.
- Missing Mom: She died before the start of the series. The Burning Clock special shows that she died shortly after her daughter was born.
- No Name Given: We never find out her name.
- Proper Lady: What we see of her, anyway.
- Strong Family Resemblance: With her daughter Miyuki/Shara, even wearing a similar dress.
Shinya Aiba/Cain Carter/Tekkaman Evil/Teknoman Saber
Voiced by: Takehito Koyasu (Japanese) / Paul Schrier (English), Rene Garcia (Latin American Spanish)
Originally one of the crew of the Argos expedition, Shinya is Blade's twin brother and arch-nemesis, following his corruption by the Radam. Skilled and merciless, he poses a real threat to Blade due to the previous bond their shared and his knowledge of his brother's weak points. Although Blade remembers his relationship with Shinya as a positive one, Shinya reveals that (on his side at least) it was filled with resentment and plagued by an inferiority complex combined with a dose of survivor's guilt following their mother's death in a fire he accidentally started as a young boy. Unlike the other Radam Tekkamen, Shinya has a a lifetime worth of bottled up personal frustrations and anger to fuel his desire to destroy Tekkaman Blade, and he does not care whether he himself survives in the process.
- Always Second Best: Or so he thinks; he and Takaya seemed about equal, from the scenes shown in flashbacks. In fact, Takaya mentions how he could never beat Shinya because his brother practiced every day and always kept himself in perfect shape. Shinya's inferiority complex stems from his fear that if his brother worked as hard as he did, he would win against him.
- Blood Knight: Utterly obsessed with killing his older twin brother, to the point where it worries the other Radam-controlled Tekkamen.
- Dark Is Evil: His Tekkaman armor is mostly black.
- Determinator: Since he was young, he was always completely focused on winning every competition against his brother. After his corruption by the Radam, he channels his determination into killing Blade.
- Died in Your Arms Tonight: With Blade / Takaya
- Drunk on the Dark Side: The Radam parasite affecting his brain might have emphasized the negative aspects of his life (his relationship with his family in particular and his feelings of guilt and inferiority) in an attempt to keep him loyal, but he certainly relished the chance to vent all his pent-up frustration and anger, to the point where it went beyond duty to the Radam and into It's Personal territory.
- Driven by Envy: He was envious of the affection and recognition received by his brother.
- Environmental Symbolism: When Takaya visits his family home, he enters the rooms of his younger siblings. Miyuki's room is intact while Shinya's room is completely overtaken by Radam plants, mirroring his corruption by the aliens.
- Eerie Pale-Skinned Brunette: Shinya is much paler than his twin brother, and combined with his creepy, menacing gaze, it gives him an unnerving look.
- Evil Twin: He's Takaya twin brother.
- Green-Eyed Monster: He expresses jealousy over Blade's relationship with Aki, and in their younger days he is shown to have been unhappy with the attention his more outgoing, popular brother received, as seen in the school race scene.
- Hair Color Dissonance: His hair is black, but in the last episode it inexplicably turns light green. This is also the color of his hair in the Twin Blood special.
- Kingpin in His Gym: One episode shows him doing one-handed push-ups while listening to classical music.
- Knight of Cerebus: While the plot is already dark, essentially his appearance is where the show gets real.
- Leave Him to Me: About Blade, because he is The Only One Allowed to Defeat You.
- Menacing Stroll
- Name of Cain: His name in the English dub.
- Names to Run Away from Really Fast: Self explanatory.
- Not Afraid to Die: He wants to eliminate Blade so much that he seems to have no room for his self-preservation instinct anymore.
- Not Brainwashed: In the dub, his Dying Speech when the Venomoid Mind Control Parasite is revealed:"I wish I could blame it all on that little thing, but the truth is, I made myself what I became. Frankly, I enjoyed being the Teknoman called Saber."
- Obviously Evil: He's Tekkaman Evil
- One-Man Army: Can wipe the floor with anything the humans throw at him. The only one who can face him for longer than five seconds is Tekkaman Blade.
- Red and Black and Evil All Over: His Tekkaman armor.
- Rival Turned Evil: Since he was a young boy, Shinya was very competitive because he felt like the unfavorite child. He believed that every single member of his family liked his twin brother better because of his cheerful and upbeat personality, and even though he always beat Takaya in every competition, he always feared that if Takaya would really set his mind to it, he would win.
- Sadist: He enjoys torturing and killing his opponents.
- Sibling Rivalry: Like you wouldn't believe.
- The Dragon: To Darkon/Tekkaman Omega.
- The Perfectionist: Takaya describes him as such, remembering that Shinya trained every day and kept himself in top condition and went all out in every competition.
- Tragic Monster: Every Radam Tekkaman counts, but he's the worst of this part.
- Twin Switch: Shinya impersonates his brother in order to infiltrate the Space Knights HQ. It works.
- Red Eyes, Take Warning: A staple of all Radam controlled Tekkamen.
- The Unfavorite: He sees himself as this because his mistake led to his mother's death. Later, he feels that everybody else prefers his more cheerful twin over him, despite his hard work.
- Used to Be a Sweet Kid: As shown in the flashbacks.
- Weapon Stomp: When fighting Miyuki.
- "Well Done, Son!" Guy
- You Remind Me of X: He creepily mentions how Aki looks like his dead mother on several occasions.
- You Should Have Died Instead: Thinks his father believes this.
Fritz von Braun/Tekkaman Dagger
Voiced By: Nobuo Tobita (Japanese), John Vickery (English), Roberto Molina (Latin American Spanish)
The first evil Tekkaman we meet, Fritz is a former friend of Takaya's and the one who gave him his iconic scar.
- Archer Archetype/Knife Nut: His trademark weapon also doubles as a bow, strangely enough.
- Blood Knight: Doesn't care about anything other than destroying Tekkaman Blade.
- Evil Former Friend: Used to be friends with Takaya.
- It's Personal: The battle where Blade manages to wound his face marks the turning point for this. He lets the scar he received intentionally unhealed because he wishes to remember the humiliation he suffered and use it to motivate him in his quest to destroy Blade. When Tekkaman Omega/Darkon tells him he decided to give the task of finishing Blade off to someone else, Dagger begs him to leave it to him instead.
- Scars Are Forever: By his own choice - he has the possibility to heal his Tekkaman form completely, but instead opts to leave the scar there as a memento of his failure.
- Starter Villain: The very first evil Tekkaman we meet, who proves to be a foe to be reckoned with. Not only does he nearly kill Blade during their first encounter, but he sets two traps in which Blade falls - the first costs him his crystal, effectively nullifying him as a threat to the Radam, and the second nearly gets him killed.
- Wounded Gazelle Gambit: He sent a distressed signal to Earth pretending to be a survivor hiding in the Orbital Ring in order to lure Blade to him. It worked.
Voiced By: Yu Shimaka (Japanese), Richard Epcar (English), Carlos del Campo (Latin American Spanish)

Feng Li/Katherine/Tekkaman Sword/Teknoman Rapier
Voiced By: Mari Yokoo (Japanese), Melodee Spevack (English)
Feng Li is the fiancée of Blade's older brother and remains deeply devoted to him even after being forced to join the Radam side. She is also the only evil Tekkaman who displays a brief moment of regret for how things turned out - if the Argos had never encountered the Radam mothership, Feng Li would have married Kengo during the voyage.
- Brainy Brunette: She was part of the Argos crew, so it stands to reason that she is a very intelligent and capable woman.
- Dark Action Girl
- The Dark Chick

When Shinya accuses him and the rest of his family of loving Takaya/Blade more than him, Kengo denies it and tells him that it's only in his head. Made sadder by the fact that it was most likely true - Shinya was loved very much by his family. He also seems to harbor some remnants of affection for his former fiancée Feng Li/Tekkaman Sword.
