A list of characters that appear in ''Zoids: Chaotic Century". Currently under heavy construction.
Van Flyheight (Ban Freiheit)
A young boy from the Wind Colony village on the outskirts of the Helic Republic. Son of a respected Helic army officer who died in an incident some time before the series proper began. He begins the series wandering around the ruins near his home, and after awakening a sleeping Organoid which he names "Zeke" (after his father's prized Command Wolf Zoid) and a Mysterious Waif who identifies herself as "Fiona", heads off on a journey to find "Zoid Eve" and restore Fiona's lost memories. Eventually, they get wrapped up in the fighting between the republic and the Guylos Empire. After helping settle the Empire's internal strife by way of dispatching Evil Chancellor Gunther Prozen, Van is offered a spot in the Republican army and parts ways with Fiona, spending a year in training and significantly increasing his piloting skill before reunitingwith Fiona and his friends to take on a new threat.
Van initially pilots the Shield Liger, an all-around Zoid specializing in the use of Deflector Shields, but towards the end of the first series, it is heavily damaged in combat against Raven's Geno Saurer and subsequently repaired/evolved by Fiona and Zeke, transforming it into the Blade Liger, which he uses for the rest of the series.
- Abnormal Ammo: Van and his Blade Liger become this in Guardian Force's finale. Being shot out of the Ultrasaurus' Wave-Motion Gun to take out the true Death Saurer.
- Ace Custom: His Shield Liger is powered-up by Zeke. As a result, its Deflector Shields can block physical attacks and even be used to ram an enemy. Battle Story Shield Liger's shield is effective against energy attacks only.
- Always Save the Girl: Van will always choose a shot at saving Fiona over anything else. Most notably in the finale where he chooses to try and save her by being shot out of a high velocity cannon instead of letting her sacrifice herself.
- Bratty Half-Pint: Goes back and forth into this in Chaotic Century. Thankfully he goes through Character Development and grows out of it.
- Bash Brothers: Has this relationship with Irvine in Guardian Force, who was previously his Big Brother Mentor.
- Beehive Barrier: Shield Liger's namesake E-Shielder. The Blade Liger keeps it, but he uses it very little.
- Big Brother Mentor: Towards prince Rudolf.
- Chronic Hero Syndrome: So much that it has come back to bite him a few times. One episode he basically saved an escaped prisoner that's from The Empire, because a group of people were ganging up on him and planning to beat him up. Van didn't care where the man was from, ganging up on someone like that is wrong in his eyes and he basically wanted them to leave the man alone. End result: while he did save the man, it caused the protagonists to become suspected as spies of The Empire. Then later on, said man he saved stole a Zoid from a Republican base, and attacked the capital which caused some casualties to innocents.
- Cool Sword: The Blade Liger's Laser Blades.
- Determinator: Van. Will. Never. Stop. Beaten down? Damaged beyond reason? A kaiju sized death machine threatening to wipe out all life? Van will get up and fight.
- Facial Markings: A small one.
- Heroic BSoD: A short one after Raven's Geno Saurer totals his Shield Liger. He goes through another short one when Fiona briefly disappears nearing the finale.
- Hot-Blooded: Van is always raring for a fight and it takes a lot to calm him down. He tones it down in Guardian Force but there are still shades of it there.
- Idiot Hero: While not as bad as Bit from New Century Zero, he can be a bit dense at times. Thankfully, he's grown out of it by Guardian Force.
- In the Blood: Van's father was something of an exceptional pilot as well, according to testimony from his mentor.
- Jack of All Stats: As far as Zoids go, the Shield Liger is a Jack extraordinaire.
- Kid Hero: In the original series.
- Kid Hero All Grown-Up: In Guardian Force.
- Magnetic Hero: Fiona tells Van that this is what makes him so powerful, and she's right. Van brings people together and people want to fight for him.
- Mecha Expansion Pack: The Attack Boosters developed for the Blade Liger.
- Mid-Season Upgrade: From the Shield Liger to the Blade Liger in the first series.
- Mr. Fanservice: After the Timeskip, when he was training in the military. His military uniform has a rare male version of a midr-ff-baring cutout, exposing his abs and he gets at least one Walking Shirtless Scene to show he's now ripped.
- Parental Abandonment: Van's father died in service. His mother is never mentioned. Instead, his elder sister Maria was Promoted To Parent.
- Save the Villain: Van will do this if given the option as shown when he tries to keep Raven from killing himself and his Zoid in one battle and later when he saves Reese from drowning.
- Screaming Warrior: Van screams a lot during combat.
- Spell My Name with an S: Ban/Bang/Van, Fleiheight/Freiheight/Flyhight
- Strong Family Resemblance: He's essentially a younger version of his late father, down to having the same hairstyle and facial mark.
- Took a Level in Badass: In between the original series and Guardian Force.
- Even during the original series. Best shown in his fights with Raven. His first fight saw Van lose with Zeke's help, and Raven not even using Shadow. In their battle towards the end of the series, Raven is using Shadow the entire time, and when Van gets his Heroic Second Wind, he nearly wins without Zeke.
- True Companions: With Fiona, Moonbay, Irvine, Zeke and Rudolph. Also Thomas.
- You Killed My Father: Van finds out at the end of the first season that Prozen killed his father. Thankfully his friends manage to keep him from losing his cool.
An Organoid (A type of smaller Zoid that can fuse with and repair and power-up the regular sort), Zeke was discovered by Van sleeping in a stasis pod in some ruins. When Van accidentally awakens him, the two immediately bond and Van names him after the Command Wolf his father used.
Following this, Zeke serves a role as Van and Fiona's Robot Buddy and trademark MacGuffin, sought after by numerous baddies and helping out Van in battle by fusing with/repairing his Shield Liger, eventually working together with Fiona to evolve it into a Blade Liger following its destruction. Zeke remains by Van's side throughout the entirety of the series.
- Animal Mecha: Like other Zoids. Zeke is a dinosaur like Zoid.
- Amplifier Artifact: Is designed to immediately enhance the capabilities of any Zoid he fuses with, even causing them to undergo an "evolution" of sorts.
- Combining Mecha: Anything he combines with gets a significant boost in power and is generally repaired to near-perfect condition.
- Dead Guy Junior: Van names him after his father's Zoid, who had been destroyed at this point along with its pilot.
- Jet Pack: Like all organoids he has one. Sometimes he uses it to carry Van around.
- Heroic Sacrifice: Was prepared to pull one along with Fiona in the finale, but Van managed to talk them out of it and defeat the Death Saurer so they didn't have to.
- Luminescent Blush: Gets one when Thomas accidentally confesses his love for him when he meant it for Fiona. Zeke responds quite positively.
- People Jars: His introduction.
- Played for Laughs: During a Vacation Episode, Thomas accidentally gives Zeke a Love Confession that was meant for Fiona and Zeke takes it quite well to the point where he becomes very friendly with Thomas and keeps trying to spend more and more time with him during the episode.
- Red Eyes, Take Warning: Subverted; Zeke's eyes are normally this color, and he is the friendliest and most tame of the Organoids. It's when his eyes turn green (due to being driven temporarily feral by the Rare Hertz scrambling his circuits) that you need to watch out.
- Robot Buddy: He's an organoid and Van's best friend.
- Team Pet: He's the resident team robotic dinosaur and gets along with just about everybody.
A young girl found in the same ruins as Zeke, with whom she shares some sort of connection. Her past is unknown even to herself, and she lacks basic knowledge about the world and the people in it. The only thing she seems to remember is a "Zoid Eve", which she and Van set out to find together. Kind-hearted, naive, and almost annoyingly cheery, she accompanies Van for most of his journey in a non-combat role, serving as a peacemaker of sorts when Van's temper gets them both into trouble.
In Guardian Force, she becomes Dr. D's research assistant, meeting up with Van again after two years. She joins the Guardian Force alongside Van, and her mysterious past becomes the key to the reawakening hostilities between the two nations currently at peace.
- Amnesiac Hero: When Van first finds her the only thing she can remember is her name. She spends a lot of time throughout the series not entirely knowing who she is, not that she really minds.
- Bizarre Taste in Food: A Running Gag is how she likes to take her coffee with salt.
- Cloud Cuckoo Lander: In Chaotic Century, especially in the beginning. Given that she's suffering from amnesia and doesn't quite understand how the world works, Fiona does a lot of silly and nonsensical things that often get her and her friends into some trouble. It's pretty much vanished by Guardian Force after emotionally maturing though. To give an example, she dumped all of her and Van's water out when they were in the middle of a desert because "it smelled funny" and saw no problems with her actions.
- The Ditz: Well, in the beginning anyways. During "Guardian Force" she has grown significantly more level headed, having experienced more about the world.
- Facial Markings: On her forehead. Notable in that while everyone has markings in this show, Fiona's are completely unique. It's a good sign that she's not a normal human.
- Fanservice Pack: By Guardian Force. Aging biologically means Fiona now sports a noticeable rack.
- First Kiss: With Van in her astral form. Doubles as Intimate Healing since this is also happening while she repairs the Blade Liger after Raven has almost destroyed it.
- Guy in Back: She rides shotgun with Van for almost all of his major battles. It's not until towards the end of Guardian Force that she no longer rides with him since the battles become far too dangerous. See Mission Control below.
- Heroic BSoD: Twice in Guardian Force. After suffering from Reese's Mind Rape on her and thinking that Van was killed. Suffers one on a smaller scale later in the season when Van goes missing after a fight with Raven and it's briefly suspected he might be injured or dead.
- Heroic Sacrifice: She tries to pull this at the end of the series by using Zoid Eve to wipe out all Zoid life along with herself in order to stop the Death Saurer. Thankfully Van talks her out of it.
- Implied Love Interest: To Van. The only thing that keeps them from being the Official Couple is an actual concrete expression of their feelings for each other despite the fact that Everyone Can See It. It's been flat out stated by Irvine that Fiona truly loves Van.
- Innocent Fanservice Girl: She has no issue with going out of the shower to talk to Van, completely naked. Grows out of this in Guardian Force.
- Intimate Healing: As part of healing the Blade Liger, Fiona kisses Van. A similar event happens in the manga to heal Van's Command Wolf.
- Mission Control: During Guardian Force she helps with the tactics of Van's squad from the Ultrasaurus.
- Mysterious Past: Even she doesn't know who she really is. She's actually an Ancient Zoidian and a survivor of an apocalypse in the distant past.
- Mysterious Waif: Van finds her in a container next to a robot dinosaur. He wakes her up and she changes his life forever.
- Naked First Impression: She's completely naked when Van meets her, with only the cables in her capsule covering her.
- Nice Girl: Fiona is probably the most pure hearted character on the show. Just don't hurt the ones she loves.
- Oblivious to Love: Towards Thomas anyway. Best shown in the Vacation Episode where he spends the whole episode trying to tell her his feelings and Fiona cannot take a hint.
- However it could be more along the lines of her just not being into him and only seeing as a friend.
- Oh, Crap!: When Fiona realizes that Prozen has resurrected the Death Saurer, she immediately tells Van they need to run.
- Oracular Urchin: In Chaotic Century Fiona seems to know way more about what's going on around her than she lets on.
- Pink Means Feminine: Both of her main outfits during Chaotic Century and Guardian Force are this.
- Plucky Girl: Especially in Chaotic Century.
- Say My Name: Towards Van all the time.
- She Is All Grown Up: In Guardian Force. Fiona has shown to have grown tremendously both physically and emotionally in just a few years.
- Single-Target Sexuality: She only cares about Van in a romantic sense, no one else, much to Thomas's sorrow. She just sees anyone else flirting with her as being friendly towards her.
- Trademark Favorite Food: Salt. Lots and lots of salt. Though this was done very early in the series to show her being silly, by the end, she's kinda grown out of it.
- Voice of Reason: She's often the one to calm Van down and suggest a more reasonable solution to their problems that don't involve fighting.
A roguish mercenary roaming the planet. He starts off as an enemy, trying to steal Zeke and sell him on the black market for a hefty price. After being defeated the first time, a few chance encounters cause his respect for Van to grow, and the two eventually join forces.
- Big Brother Mentor: Towards Van. Irvine is clearly the more experienced pilot when they first meet, however by the time Guardian Force rolls around, Van has surpassed him in every way.
- Badass Longcoat: Gets one briefly as a disguise when he comes back in Guardian Force. Loses it by the end of the episodes unfortunately.
- Changed My Mind, Kid: He keeps trying to steal Zeke from Van in his first few appearances and acts like he's only it for himself, only to repeatdly come to Van's rescue and eventually joining up with him for good to join the search for Zoid Eve.
- Establishing Character Moment: Irvine meets Van and Fiona, a couple of kids, wandering in a sandstorm with no food or water so he provides them both, all while grilling them for information on what they're doing without giving away his true intentions. When he finds out Van has an organoid, Irvine ditches Van and tries to steal it. This helps establish his Jerk with a Heart of Gold tendencies, not willing to let a couple of starving kids die in front of him but more than willing to steal their Amplifier Artifact for himself.
- Eyepatch of Power: His eye is perfectly fine; the patch gives him scanning tech, and contains some miniature tools.
- Fragile Speedster: The Lightning Saix is the fastest Zoid on the show, but it doesn't have a lot going for it defensively.
- Insistent Terminology: No, he is NOT a member of the Guardian Force!
- Jerk with a Heart of Gold: In the first season, he constantly snarks at Van and generally acts very distant, but is willing to come through for the gang when things get tough. He's a lot less jerkish in Guardian Force.
- The Lancer: Serves as Van's number two, especially in Guardian Force when he comes back.
- Mid-Season Upgrade: He upgrades from his Command Wolf to a Lightning Saix after the Wolf gets totaled.
- Shipper on Deck: Subtle and not as obvious as Moonbay, but Irvine is at least very aware that Van & Fiona are a couple to the point where Irvine is the one that spells it out for Thomas that he has no chance with Fiona.
- Ship Tease: Gets a little with Moonbay every so often, but sadly not much.
- Vitriolic Best Buds: Has this relationship with Van at first.
- You Are Not Ready: When he desires to pilot the Gojulas, he's told this. It stems from his desire to be stronger than Raven and Van after the former handed him his ass twice and the latter is slowly surpassing him. By the end of Chaotic Century though he gets over it and gets to pilot a black Gojulas.
A transporter of the wasteland that pilots a Gustav transport, Moonbay meets Van and Fiona by chance while running some explosives and helps him repair his Shield Liger after it's damaged. After she destroys her cargo to save the group, she decides to have Van act as her bodyguard in order to pay her back. Soon after Moonbay signs an agreement for the group to act as mercenaries for the Helic Republic, which kicks off the group traveling together while trying to find Zoid Eve.
During the Time Skip, Moonbay returns to being a solo transporter. After coming across an injured Thomas and his Dibison, she saves him and brings him back to the Guardian Force where she's reunited with Van and the rest of her friends. Late in the series she becomes the pilot of the Guardian Force's Ultrasaurus.
- Action Girl: She gets in on fights despite piloting a weaponless transport Zoid.
- Ambiguously Brown: Her skin is a darker tone than the others.
- Anger Born of Worry: Has this towards her friends, especially Van. She straight up punches him in the face at the end of one episode because he almost got himself shot while trying to be a Nice Guy.
- Cool Big Sis: Has this relationship towards both Van and Fiona, but mostly Fiona.
- Dreadful Musician: She's found of singing while transporting. However, most of the other characters can't stand it.
- Early-Installment Weirdness: Moonbay has a much deeper voice in her first appearance, to the point that you would think that she had a completely different Voice Actress.
- Genki Girl: She's incredibly energetic.
- Giftedly Bad: She thinks she's a great singer. She's anything but.
- Ms. Fanservice: Moonbay gets several attractive outfits throughout the series. Most notably her appearance in Guardian Force where her outfit now shows off more skin, she has a noticeably larger bust and even gets to wear a skintight racing suit in one episode.
- She Cleans Up Nicely: When the group runs into an old flame of hers. Moonbay puts on a dress, straightens her hair and she is gorgeous.
- Shipper on Deck: Ships Van x Fiona with a passion.
- Ship Tease: With Irvine at points, but it never develops into anything substantial.
- Stone Wall: Her Gustav zoid sacrifices offense for an extremely tough armored shell. Its tough enough to nearly withstand a point-blank blast from Raven's Genobreaker.
- Wrench Wench: Moonbay serves as the team's mechanic during 'Chaotic Century'.
Rudolf Gerhardt Zepplin III
Nominally the Emperor of Guylos, Rudolf is merely a child who ascended the throne prematurely due to the death of both of his parents and his grandfather.
- Big Brother Worship: Towards Van, despite them not being related.
- Distressed Dude: Frequently getting kidnapped, but its justified in that he's royalty that everybody wants to get a hold of for their own agendas, and he's only a child with very little combat skills.
- Reasonable Authority Figure: Is always this, both before and after his coronation.
- Royals Who Actually Do Something: He's in line for the throne and very kind, compassionate, and eager to help his friends and citizens. After coronation he becomes an emperor.
- Stockholm Syndrome: Develops a bit of this with Rosso and Viola, two bandits that kidnapped him. It helps that they protect him from the real bad guys who are trying to murder him, and the fact that his Grandfather, who presumably raised him, had just died not days prior.
- Took a Level in Badass: Becomes a fairly competent Zoid pilot under Van's tutelage. Even winning a Zoid race in the sequel.
- Wise Beyond Their Years: It should be noted that this kid is only eight for part one, and ten after the Time Skip. Outside of occasional rare flashes of naiveté due to his age, it doesn't stop him from being a frequent voice of reason, and eventually becoming Emperor of Guylos.
Thomas Richard Schwarz (Thomas R. Schubaltz)
A new member to the group, Thomas is an Imperial soldier who joins up with the Guardian Force to help peacekeep Zi as part of a joint operation with the Helic Republic, and is thus assigned as Van's partner as the Empire's representative. Thomas is also the younger brother of Colonel Karl L. Schubaltz, someone that Van and the Helic Republic fought against in the previous war. It takes awhile for Thomas to warm up to Van due to their contrasting personalities and due to his own crush on Fiona and his insecurities in trying to confess his feelings, however eventually the two form an effective friendship and work better as a team.
Thomas pilots a Dibison and uses a personal AI that he built called BEEK to assist him in combat. Interestingly enough, Thoma is the only character on the team who never gets a new Zoid, sticking with the Dibison throughout the course of the show.
- All Love Is Unrequited: Towards Fiona, who very clearly is in love with Van; it's also pretty much Thomas's defining feature for the series sadly. This poor guy cannot take a hint that Fiona not only is not inot him, but she doesn't even realize Thomas is into her or doesn't acknowledge it!
- I Want My Beloved to Be Happy: Once Irvine tells him that Fiona is in love with Van, he backs off on trying to confess his feelings and win her heart. In the same episode he also does all he can to reassure Fiona that Van (who is currently MIA) is alive and that they're going to find him. He's still clearly in love with her but he wants her to be happy, even if that means being with another man.
- Always Someone Better: His older brother is this to him. Thomas feels that Karl is better than him at everything with the exception of handling computers and machines.
- Thomas also starts feeling like this towards Van when he becomes an Unknown Rival to Van.
- Big Brother Worship: Towards his older brother, Karl, who is a respected officer in the military.
- By-the-Book Cop: Thomas is easily the most disciplined member of the group, and as such not as willing to go off book and improvise as much. He prefers having a dedicated plan of attack.
- Calling Your Attacks: MEGALOMAX!
- Cannot Spit It Out: His feelings to Fiona. There's an entire episode devoted to it.
- Establishing Character Moment: His first appearance has him holding Van at gunpoint because he thinks he's a bandit trying to hurt a mother with her child (who is actually just Fiona protecting a girl but not from Van) and then immediately falls for Fiona upon seeing her and refuses to let up on Van until he can get official confirmation of who he is. This establishes that Thomas is a heroic, By-the-Book Cop that will follow protocol no matter what, something that is admirable but will often get him in trouble for not being able to improvise. Also it establishes his hopeless crush on Fiona.
- My Friends... and Zoidberg: Pretty much how everyone treats him due to his Insufferable Genius tendancies and his inability to take a hint. Normally a character in his position would become the Sixth Ranger to the team, but man this poor guy never gets a chance to outgrow his Establishing Character Moment.
- Butt-Monkey: Thomas gets subject to a lot of punishment, both comedic and not so much. If someone needs to get slapped around, it'll be him.
- Intelligible Unintelligible: He's the only one that can understand the beeps and computer noises that BEEK makes, which makes sense since BEEK is his personal AI and is only designed to help him.
- Love at First Sight: He falls for Fiona the second he lays eyes on her...ttoo bad it is very unrequinted.
- More Dakka: His Zoid is a Dibison which is pretty much built around this trope.
- The Smart Guy: He's between this and The Lancer at least until Irvine comes back.
- The World's Expert on Getting Killed: This poor guy is just unlucky as Hell.
- The Unfavorite: Thomas believes he is this in the family, thinking that his older brother got all the attention when they were younger. He still looks up to his older brother, however, and has a rather hard time bringing himself to fight his brother when he's Brainwashed and Crazy.
- Unknown Rival: Thomas is constantly, constantly trying to outdo Van whether it be in piloting or trying to earn Fiona's affections. Not only does he fail everytime, Van either never notices or doesn't care about his one-sided rivalry!
- The Worf Effect: When Raven comes back on the scene, the first thing he does is kick Thomas' ass in a Beam-O-War.
A prodigious young man serving as the Empire's trump card. Raven is a deeply troubled boy who hates Zoids despite being one of the best pilots around. He serves as a rival and foil for Van, being roughly the same age and possessing an organoid of his own.Van eventually manages to hold his own against the young prodigy, defeating him twice. The two are initially drawn into conflict due to being on opposite sides of the Republican/Imperial war, but Raven eventually becomes obsessed with defeating Van after suffering a near-death experience at his hands.
In Guardian Force, Raven re-appears to antagonize the Guardian Force and finally settle his vendetta with Van. With the war between the Republic and the Empire ended and Prozen out of the picture, Raven now fights only for himself and his own satisfaction. In the meantime, he forms a friendship with the mysterious Blue Devil Reese and is manipulated by the maniacal Hiltz into causing as much destruction as possible.
Raven initially pilots a Saber Tiger enhanced by his organoid, Shadow. When Van eventually destroys it, Raven upgrades to the vastly superior and experimental Geno Saurer, which is then evolved by Shadow into the incredible Geno Breaker.
- Ace Pilot: Raven is arguably the strongest pilot on the show, perhaps even stronger than Van. A good portion of Guardian Force has the heroes from both nations coming together in order to formulate a plan to take down Raven and his Geno Breaker.
- Break the Haughty: His defeat in the penultimate episode of the first season traumatizes him so badly that he's reduced to an empty shell wandering the planet. He snaps out of it after encountering Van again.
- Char Clone: He pilots a red Zoid (a Saber Tiger in Chaotic Century, the Geno Breaker in Guardian Force), and is The Rival to Van.
- Combat Pragmatist: Quite often the heroes will be over powered by Raven because he keeps finding new ways to get around their strategies for beating him. Van's Blade Liger shield is now strong enough to endure the Geno Saurer's Wave-Motion Gun? Fire the rest of his guns along with it. The Geno Breaker lost its foot locks to safely fire the same gun? Do it from the air.
- Curb-Stomp Battle: Easily defeats Van in their first battle without even using Shadow. Van does better with Zeke's help in the second fight, but then Raven calls Shadow and defeats Van, nearly killing Van.
- Once he gets his Geno Saurer, all of his fights are this until Van defeats him towards the end of the series.
- Defrosting Ice King: This happens late in the Time Skip Guardian Force when Shadow is killed, as in spite of his hate for Zoids he sincerely moured over Shadow's death shown further of this when it seems that Hiltz killed him and Reese, which they survived, what happened offscreen is Reese apparently caught a fever and he went out of his way to take care of her and in general when shown that scene he was being generally rather gentle and compassionate with her when watching over her which is new as before it was shown he didnt like Reese one bit. All of this and getting a revived Shadow back after he tamed him again when he was feral again, which instead of aggressively fighting back, he petted him instead. eventually lead to his Heel–Face Turn.
- Empty Shell: When he first reappears in Guardian Force, Raven can barely be classified as a person. He just silently wanders the wasteland, completely destroying military bases and annihilating Zoids using other Zoids that Shadow steals for him. He eventually gets back to his old self...for better or for worse.
- Evil Counterpart: To Van. Like Van, Raven is a teenage Ace Pilot who owns an organoid. However while Van fights for his friends and is loved by others, Raven fights only for himself and is hated. He gets better towards the end of the series.
- Even Evil Has Loved Ones: Raven's only ever cared about three sets of people: his family, his organoid, and, at the end of the series, Reese.
- Evil Is Bigger: Not Raven himself, but once he gets the Geno Saurer, the Zoids he pilots are bigger than Van's.
- Hero Killer: Aside from his incredible kill count that he racked up during the first war, Raven is personally responsible for wrecking the heroes' Zoids and not prompting one, but two Mid-Season Upgrade for both Van and Irvine. His return to the series in Guardian Force is also marked with him trashing Thomas and his Dibison.
- Invincible Villain: Raven almost never loses. Taken up even further in Guardian Force when he gets his Geno Breaker, as the heroes are never able to defeat him. note
- Karma Houdini: Raven kills a lot of people and Zoids over the course of the show but by the finale he's allowed to go free. Sure he did help the heroes save the planet and has changed his outlook on life, but that doesn't really change the fact that for 90 percent of the show he was a huge Jerkass that caused the heroes no end of grief. He even gets a Love Interest to take with him!
- Knight of Cerebus: Raven is almost entirely a serious character thanks to his love of violence.
- Love Redeems: His growing feelings for Reese contribute to his Heel–Face Turn late in Guardian Force.
- Not Distracted by the Sexy: During Guardian Force Reese tries to seduce him at one point while also brandishing a knife, but Raven notices and knocks her off before she can hurt him. She does manage to cut open his cloak though, and even Raven admits that he'll never let her get that close again.
- Never My Fault: When he loses against Van's Shield Liger during the battle for New Helic City, Raven blames the Zoid, not the fact that he tried to fight Van while damaged and also tried to muscle his way through Van's energy shield.
- Parental Abandonment: His parents were obsessed with studying Zoids, much to Raven's resentment, and this proves to be their undoing when they are ripped apart by an Organoid (Ambient).
- The Rival: To Van, eventually. It's telling that the only thing that Raven wants to accomplish for most of Guardian Force is to kill him.
- Sadist: Raven loves to torture his victims before offing them for good. Best shown when he has Irvine down for the count and he decides to keep stepping on the Command Wolf to make it cry out it pain.
- Start of Darkness: As a child, his parents were murdered by an organoid (strongly implied to be Ambient), and he suffered a blow to the head that gave him amnesia. After that, he was taken in by Prozen, who personally trained him to be a remorseless killer.
- The Only One Allowed to Defeat You: Says this nearly word-for-word in the finale, where he saves Van from a fatal attack by Hiltz's Deathsaurer.
- Used to Be a Sweet Kid: As a child Raven was a very friendly and happy kid. Then his family was killed and he was kidnapped by Prozen and trained into an emotionless soldier.
- The Worf Effect: Raven proved invincible once he got his Geno Breaker. Rather than the heroes defeating him, he's nearly killed by Hiltz to demonstrate the power of his Death Stinger.
An organoid owned by Raven. A solid jet black in contrast to Zeke's white, he serves as a rival of sorts for Zeke as well as a foil. Where Zeke is willful and disobedient, Shadow is unswervingly loyal to Raven; where Zeke is free spirited and whimsical, Shadow is almost robotically efficient. Despite being an excellent partner, Shadow suffers from Raven's abuse due to the boy's pathological hatred of Zoids. Regardless, Shadow stays by his side no matter what, and is fiercely protective of his young master.
- Amplifier Artifact: Like all organoids he can drastically alter the abilities and power of a Zoid he fuses with. Specifically Shadow can overclock a Zoid for a short time period but once he reaches his limit he has to disengage from the Zoid's core. The one time he doesn't do this in time has some disasterous results.
- Came Back Wrong: When Prozen revives him from the dead, Shadow doesn't respond to Raven at all and even attempts to kill him on Prozen's orders at first.
- Defeat Means Friendship: The reason that Shadow is Raven's organoid to begin with is because Raven physically dominated Shadow when they first met, earning Shadows loyalty and respect.
- Evil Counterpart: To Zeke. Zeke is white, Shadow is black. Zeke is expressive, friendly and heroic whereas Shadow is stoic, violent and the partner of a villain.
- "I Know You're in There Somewhere" Fight: After Prozen revives him, Shadow can't remember who Raven is and attacks him. After going at each other for a few rounds, Shadow regains his memory of Raven and snaps back to his old self.
- Taken for Granite: As a result of using up all of his power and staying fused with the Geno Breaker for too long, Shadow turns into stone late in the series.
- Undying Loyalty: To Raven.
Gunter Prozen (Gunther Proitzen)
A commander in the Guylos Empire, Prozen is a man with ambitions of ruling the the world which helps him serve as the show's primary Big Bad. Prozen spends a great deal of time in the first season trying to manipulate/remove Rudolph from power so that he can rule over the empire. By the end of the Chaotic Century he also recreates the legendary Death Saurer which he plans on using to conquer the plane. However he's defeated by Van and Fiona and is seemingly killed as the Death Saurer explodes.
....or so it seems. Turns out that Prozen not only survived but has renamed himself as the Dark Kaiser and has orchestrated the terrorist attacks by Hiltz and Reese and tries to resurrect the Death Saurer yet again. He ends up getting usurped by Hiltz and serves as the True Death Saurer's core.
- Big Bad: Of Season 1. Initially appears to repeat the role for season 2 before Hiltz hijacks the role.
- Body Horror: As the Dark Kaiser, he has fused with the core of the True Death Saurer to the point where it looks like he's welded together with the thing. And that's before Hiltz turns on him.
- Disney Death: He appears to die a fiery death at the end of season 1, but he turns out he survived, albeit much worse for wear.
- Evil Chancellor: He's a minister in the Empire and he wants to rule it all.
- Faux Affably Evil: Puts on a polite and gentlemanly act, but none of it is real.
- Knight of Cerebus: Season 1 started as a mostly lighthearted adventure with the only antagonists being groups of bandits and the war between the Republic and the Empire being an event in the background. Then Prozen shows up, and the threat of the war move the forefront of the plot.
- Non-Action Big Bad: Notable that every other antagonist in the series is shown to be a somewhat skilled pilot or at the very least takes part in combat. Not Prozen. He sends his lackeys to do his dirty work.
- The Man Behind the Man: Plays this role to Hiltz in Season 2, until the latter betrays him.
- Regent for Life: His plan in Season 1.
- The Sociopath: He really doesn't care who he needs to crush in order to get what he wants.
- That Man Is Dead: He no longer considers himself Prozen after becoming the Dark Kaiser, even as Raven keeps calling him by his name anyway.
- Treacherous Advisor: He acts like he's loyal to Rudolph and wants what's best for him, but that couldn't be further from the truth.
- The Unfought: Nobody ever actually has a battle with him. Unless you count fighting the True Death Saurer since he becomes its core, but that's hardly Prozen at that point.
- Walking Spoiler: His identity as the Dark Kaiser is kept a secret throughout the entire second season, only showing up in the last four episodes.
The main antagonist of Guardian Force and an ancient Zoidian just like Fiona. Hilz is a man with an ambigious agenda throughout the season and wrecking havoc wherever he goes. His main objective is to have the ancient Zoidians return to power over Zi, even if it means wiping out all human life in the process. Just like Van and Raven, he possesses an organoid of his own named Ambient.
Hiltz pilots the Death Stinger at first before being defeated by the Guardian Force, after which he retreats to Zoid Eve and resurrects the True Death Saurer and fuses with the beast.
- Ax-Crazy: Once he gets his hands on the Death Stinger, he immediately embarks on a reign of terror across Zi. It culminates with him using the Ultimate Death Saurer to destroy several cities at once.
- Bad Boss: He has no problem with offing underlings that fail him or just getting rid of them once he no longer has a use for them, yet for some reason he has an endless supply of soldiers that he makes use of throughout the season.
- Big Bad: Of Season 2.
- Eviler than Thou: Proves this to Raven and Prozen.
- Evil Redhead: Red hair and the most evil character in the show.
- Fantastic Racism: In the finale it is revealed that his true goal all along was to wipe out all of the humans on Zi. This is because he is an ancient Zoidan and believes that only their kind have the right to rule and live on the planet.
- Faux Affably Evil: The few times he interacts with the cast directly, he puts on an air of detached civility.
- The Juggernaut: When using the Death Stinger. Raven, who had previously been an Invincible Villain with his Geno Breaker, was powerless against Hiltz. Taken up even further when he takes control of the True Death Saurer.
- Kill All Humans: His apparent goal.
- Nice Job Fixing It, Villain: If he had just waited to turn on Reese and Raven after defeating the Guardian Force, he might have gotten away with his plan.
- Offscreen Villain Darkmatter: Hiltz has an endless supply of Zoids and cutting edge military hardware, which no explination as to where he's getting it from since he's the most wanted man in the known world.
- Omnicidal Maniac: His ultimate goal is to wipe out everyone on Zi using the Death Saurer.
- The Sociopath: Cares for nobody but himself.
- The Starscream: To Prozen.
- Where Does He Get All Those Wonderful Toys?: Hiltz is a terrorist wanted by both major countries on the continent yet it is never explained exactly where his endless supply of Zoids come from nor his army of mercenaries. Considering how blase he is about killing the people that follow him it's curious as to why he has any support at all.
- You Have Out Lived Your Usefulness: Once Reese and Raven have served their purpose to him, he tries to have them killed.
Hiltz's subordinate and another ancient Zoidian, Reese operates primarily in psychological warfare and sometimes literal Mind Control. She serves as a recurring threat to the Guardian Force throughout the series up until Hiltz decides he no longer needs her, after which she joins Raven. She also has her own oragnoid, Specular.
- Bitch in Sheep's Clothing: She plays an innocent and scared girl when Van and Fiona first find her. Turns out she's anything but.
- Dark Action Girl: She does her share of fighting in her first few appearances and sports some impressive custom Zoids. She is also not a very nice person.
- Dark and Troubled Past: As a young girl, Reese was rescued by a boy named Nichaleo and brought back to his village where he nursed her back to health. However Nichaleo would later be killed during an attack by the Helic Republic, causing her Start of Darkness and wanting to take revenge on the world.
- Dark Chick: Initially the Big Bad's right hand woman, with some mind control powers, but later starts a romantic relationship with an (anti) hero, and switches sides.
- Even Evil Has Loved Ones: Nichaleo was very important to Reese, hence why his death was the catalyst for her campaign with Hiltz against the Helic Republic and Guylos Empire. She's also quite fond of her organoid, Specular, and is relieved to see that it survived after Hiltz tried to kill her. Then of course there's her relationship with Raven at the end of the series.
- Evil Counterpart: To Fiona. Fiona is gentle, sweet and is quick to trust/help others. Reese is rough, vengeful and manipulates others for her own personal gains. Furthermore both are Implied Love Interests to ace Zoid pilots (who are also counterparts to each other) and both are ancient Zoidians.
- Heel–Face Turn: At the end of the series she leaves Hiltz and joins with Raven.
- Honey Trap: She tries to pull one of these on Raven during an early meeting in order to pull a knife on him. She gets close but Raven sees through it before she can hurt him.
- Implied Love Interest: To Raven.
- Karma Houdini: She never gets any sort of punishment for all she did under Hiltz. At the end of the show she gets to leave peacefully and live happily with Raven.
- Manipulative Bitch: Most of her strategies when dealing the opposition involve getting into their head, either with psychic powers or words, and breaking them down. However whenever the tables are turned on her she's quick to fold such as when she pulled a Mind Rape on Fiona who also ended up seeing Reese's own memories.
- Mind Control: Her primary method of antagonizing the heroes in her first few appearances. She uses machines to take over people's minds and perform her bidding.
- Mind Rape: Pulls one of these on Fiona at one point and attempts it on Raven during an encounter with him. However in the latter it was more of a case of Break Them by Talking.
- Morality Pet: She becomes this to Raven, who slowly seems to care more and more about her well being.
- Pest Controller: She uses blue beetles as her minions which help with her Mind Control powers. Somehow.
- Psychic Powers: She can manipulate people's minds, showing them things that aren't real and even force them to do her bidding.
- Say My Name: Towards Raven. She spends the last couple of episodes screaming his name and not doing much else.
- Spell My Name with an S: Hoo boy, that's just the beginning. There's been Reese, Rize, Rease, Rhyss, Liese to name a few.
- Tom Boy: In contrast to Fiona's Girly Girl, she has short hair and is very brutish, lacking feminine qualities. In the Japanese version she even uses the boku instead of feminine pronouns.
The Death Saurer
The beast of destruction. An unstoppable juggernaut from the past. The Death Saurer is without a doubt the most dangerous and most terrifying Zoid in the series. Originally a weapon that was created by the ancient Zoidans, the Death Saurer is responsible for wiping out the ancient Zoidan culture and as a result illicits an appropriate Oh, Crap! reaction whenever it comes up.
The Death Saurer was resurrected by Gunter Prozen and was to be used to conquer the known world with its incredible power. However thanks to the combined efforts of heroes from both the Guylos Empire and the Helic Republic the beast was destroyed and Prozen was defeated, finally putting the beast of legend down.
Until the end of Guardian Force however. It turns out that the Death Saurer that Prozen resurrected was nothing but a cheap imitation and was not the True Death Saurer which was the actual Zoid that wiped out the ancient Zoidans.
- Adaptational Badass: The Death Saurer in The Battle Story was powerful and a huge game changer, but ultimately fell out of favor when newer Zoids were introduced. The Death Saurer of this series is a unique, and all but unstoppable Zoid.
- Artifact of Doom: This thing wiped out the ancient Zoidans, which is why Fiona freaks out at the mere presence of it. When revived it starts to attack everything in sight.
- Attack of the 50-Foot Whatever: Even for a Zoid this thing is gigantic. The real one is even larger.
- Berserk Button: It goes nuts and awakens early when it senses Fiona, an ancient Zoidian.
- Came Back Strong: The True Death Saurer in Guardian Force was revived thanks to its core and the core of the Death Stinger fusing, making it stronger than ever. On top of this its Charged Particle Intake Fan is replaced with a Charged Particle Converter, so it can't be jammed.
- The Dreaded: This thing freaks out everybody who hears about it. It's first appearance is enough to unite two warring nations in order to fight it. Its second appearance immediately causes Raven and Reese to do a Heel–Face Turn, and forces to heroes to break out a friggin' black hole gun in an attempt to face it.
- Final Boss: The last great threat that the heroes face in Chaotic Century. And again in Guardian Force.
- Generic Doomsday Villain: It's a Zoid so it has no dialogue. It's only characterization is that it's a killing machine that attacks everything in sight.
- Giant Equals Invincible: The Death Saurer is far larger than normal Zoids and it is virtually indestructible. The real one is larger and even stronger.
- Gone Horribly Right: The ancient Zoidans built the Death Saurer to end all wars. It did...by killing most of them.
- Glowing Eyes of Doom: Keen emphasis on the "doom" part.
- It Only Works Once: Sort of. It's technically not the same Death Saurer the second time around, but the method of jamming its Charged Particle Intake Fan doesn't work on the Ultimate Death Saurer because it uses a Charged Particle Converter instead.
- The Juggernaut: The Death Saurer is seemingly invincible. The only way that Van is able to defeat it each time is to have everyone helping him to some capacity while he goes for the core.
- Kaiju: Obviously the intent. The Death Saurer dwarfs everything else in the series.
- Leitmotif: Complete with ominous bells that really sells the whole "harbinger of the apocalypse" angle. 
- Mechanical Abomination: The Death Saurer isn't any normal Zoid, rather it's an a nigh unstoppable civilization destroying monstrosity. Notably, it has a malevolent will of its own and is able to influence and control people into helping to resurrect it.
- Oh, Crap!: The general response by the very presence of it.
- Names to Run Away from Really Fast: It's called the Death Saurer.
- No-Sell: The Death Saurer is virtually indestructible. The real one is even more so, a point blank shot from the Geno Breaker's Charged Particle Cannon has no effect thanks to its Deflector Shields. It takes all of the Geno Breaker's power, with Shadow's aid, just to break the shield.
- Rent-a-Zilla: The anime even adjusts the design from the model line to make the Death Saurer look more Godzilla like in appearance.
- Sealed Evil in a Can: The core was hidden away and Prozen unearthed it to clone the body to resurrect the Death Saurer. By Guardian Force we see that the original body was also left intact and was much more of a threat once reunited with its original core.
- Turned Against Their Masters: The Death Saurer was built to serve the ancient Zoidans, but it ended up being too powerful for them to control.
- Wave-Motion Gun: The Death Saurer's Charged Particle Cannon. Unlike the Geno Saurer it can move freely while firing it.
An effeminate mercenary who aids Prozen's mercenaries in the plot to assassinate Crown Prince Rudolph; however, he's truly after the organoid Zeke. He's nicknamed The Fisherman due to tendency to luring his catch and watching them suffer; which he does so via poison. Though he was able to help obtain Rudolph's Imperial Ring, he wasn't able to finish the job, as he was defeated by Van's newly-evolved Blade Liger. Appears in both Chaotic Century and Guardian Force.
- Beware the Silly Ones: Make no mistake, behind his Camp Gay demeanor lies a lethal assassin.
- The Bus Came Back: He returns in Episode 43 of Guardian Force.
- Camp Gay: One of the most effeminate characters in the series, and he also pilots a pink Guysack and a pink Saber Tiger (Stinger Special). He also blew a kiss to the mercenaries to taunt them when he first incapacitates them with poison gas. In addition, he orders milk from bars for beauty purposes.
- Even Evil Has Standards: After escaping from jail with the help of the Trinity Ghost scientists (and bumping into the Crossbow Brothers in the process), he decides that being free would be meaningless if he simply allowed the world to be destroyed by Hiltz. Most likely he was killed off, but you gotta give him points for trying.
- Laser-Guided Karma: After his Saber Tiger was taken out by Van's Blade Liger, a cured and pissed-off Moonbay socks him as payback.
- Poisoned Weapons: His main specialty, which he uses to poison Moonbay and Irvine by spiking their soup.
- Red Baron: He's nicknamed The Fisherman, and for good reason!
- Uncertain Doom: In Guardian Force he and the Crossbow Brothers take a final stand against Hiltz and the Death Stinger, only to be on the receiving end of a Charged Particle Cannon Blast when the madman destroys the prison they were in. So it's most likely they were killed in their effort.
- Wolverine Claws: His secondary weapon.
- Wounded Gazelle Gambit: He infiltrates the group by pretending to be attacked by Prozen's mercinaries, allowing Moonbay to rescue him. Only Irvine was suspicious.
Schubaltz's power-hungry and opportunistic second-in-command. Only appeared in Chaotic Century.
- Attack! Attack! Attack!: His primary strategy - which often costs him greatly due to his incompetence.
- Bad Boss: He's willing to sacrifice his men just to get himself promoted. Example being that he had ordered Rosso and Viola to attack their forces in a Republican Pteras so that they could break a stalemate while giving them a chance to rejoin the Imperial Army. However, Marcus reneged on his offer, betraying them (due to an unforeseen outcome).
- Fatal Flaw: Greed. Especially when it comes scheming to get a promotion, which was shown several times during his appearance.
- His hasty nature, combined with his forces' attempt to advance toward Cronos base result in the unit being taken out by a trap, caused by the Repulicans rigging the base to self-destruct.
- His final attempt to claim victory by taking over the Mt. Osa base would cost him his life, with the erupting volcano engulfing his Iron Kong as a result.
- Foil: To O'Connell - while O'Connell displays undying loyalty to Herman, Marcus can't stand Schubaltz, bad-mouths him behind his back, and wants him disposed of so that he can take over his position in the military.
- Hate Sink: Cocky, stubborn, and power-hungry, this man never learns from his mistakes.
- Never My Fault:
- He was the one to order the Desert Arcobaleno Gang to use a Republican Pteras to break the stalemate at Red River, and when that failed, he laid the blame on them, sending out the Imperial Army for their arrest.
- His final words involve blaming Schubaltz for thinking he could steal his credit for taking over the Mt. Osa base. Boy was he wrong.
A former soldier of the Empire that was dishonorably discharged and became a bandit as a result. Rosso is the leader of a group of bandits called the "Desert Arcobaleno Gang" and is desperately looking for a way to prove his worth to the Empire in order to retrieve his former position in the military. His gang serves as antagonists for Van's group early in the series before the conflict of the Empire and the Helic Republic come into play.
After being set up as a Patsy yet again for the Empire, Rosso is imprisoned but then later broken free by his gang who then decide to give up trying to rejoin the empire and to just kidnap the crown prince Rudolph for a huge ransom. Rosso and Viola end up bonding with Rudolph and protecting him from Prozen's assassination attempts. They then help him escape with Van when Raven comes hunting. Rosso reappears later in the season as one of flying aces of the Helic Republic, the Red Masked Baron of Wings piloting a Stormsworder.
Rosso pilots several Zoids, starting with a Red Horn in his first appearances, then briefly an Iron Kong after busting out of jail and then his Storm Sworder for the rest of the series.
- Ace Pilot: He's the strongest pilot in his gang, but he best fits this trope while piloting a Storm Sworder.
- Big Damn Heroes: Pretty much every time he and Viola swoop in their Storm Sworders they're invoking this trope.
- Disney Death: He and Viola appear to be killed by Raven roughly halfway through Chaotic Century, but they turn up fine later.
- A Father to His Men: Rosso's gang love him so much that they're more than willing to break him out of prison after taking the fall for them.
- Heel–Face Turn: Turns on the empire and becomes an ally to Van and the others after bonding with Rudolph.
- Heroic Sacrifice: He and Viola give one for Rudolph by holding off Raven's Geno Saurer so that Rudolph and the others can get away.
- Large Ham: As the Red Masked Baron of Wings. He loves hamming it up and giving a Badass Boast or two.
- Parental Substitute: To Rudolph, who even goes as far as to refer to Rosso and Viola as his parents.
- Paper-Thin Disguise: His Storm Sworder persona. To be fair, most people who go up against him wouldn't see him in person since he's flying around and his Large Ham tendencies mask his real personality completely, but one look at his outfit immediately gives away who the Baron is.
- Red Baron: The Red Masked Baron of Wings.
- Spanner in the Works: If Rosso's gang hadn't chased Van into the Zoid ruins at the start of the show, he never would have found Fiona and Zeke, never would have repaired the Shield Liger, which never would have been transformed into the Blade Liger and it would have never had defeated the Death Saurer.
- His plan to kidnap Rudolph ruins Prozen's assassination attempt on him.
- Starter Villain: His gang is the first major threat that Van and his friends face.
A former Imperial soldier and the second in command of Rosso's gang, Viola is a crackshot aerial plot that serves as another antagonist to Van and the others at the start of the series. Viola hails from the hidden village of Mt. Iselina which has remained neutral in the conflict between the Helic Republic and the Guylos Empire. Viola, however, was not satisfied with doing nothing but hiding in their village while a war waged on, so she left the village to join the Empire in order to make a difference and protect her younger sister Rosa.
At some point Viola also left the military, either of her own free will or through a dishonorably discharge like Rosso. Viola is fiercely devoted to Rosso and would do anything for him, including break him out of prison. After Rosso gives up on trying to get his old position in the military back, they decide to kidnap Prince Rudolph for a huge ransom, only to end up saving him from Prozen's assassination attempts instead and helping him escape with Van when Raven comes to kill him. After being saved by Captain Herman, Viola joins the Helic Republic as one of their Storm Sworder flying aces.
Viola only pilots aerial Zoids, her first being a red Redler and her second being a Storm Sworder.
- Ace Pilot: As one of the Republic's Storm Sworder pilots, she's this. Notably she was a pretty good Zoid pilot even before the upgrade.
- Big Damn Heroes: Her main role as a Storm Sworder pilot, always swooping in to save the day. Most notably played straight when she saved her sister from the Death Stinger and when she and Rosso ferried Van and Irvine back to the Ultrasaurus.
- Disney Death: She appears to die along with Rosso while holding off Raven, but she turns up fine later.
- Facial Markings: The same ones as Rosso and the rest of his gang. Given that she didn't have them in a flashback, she probably got them after joining up with him, which is more of an explanation than anyone ever gives as to why everyone in this show is always wearing war paint.
- Heel–Face Turn: Pulls one along with Rosso, joining the Helic Republic after Raven tries to kill them.
- Heroic Sacrifice: Pulls one alongside Rosso to help Rudolph escape from Raven along Van.
- Home Field Advantage: When fighting with Van at Mt. Iselina, she lures him into the valley to mess with his senses. Since she grew up in this place, she knows all the tricks she can use from the environment to beat him. She only loses because her little sister bails Van out.
- Mama Bear: Hurt Rudolph or her little sister and you will regret it.
- Ms. Fanservice: Both her Zoid pilot uniforms show off her curvaceous figure.
- Parental Substitute: To Rudolph alongside Rosso. He even goes as far to call them his parents. Also one to her sister, Rosa.
- Paper-Thin Disguise: Her identity as one of the Storm Sworder aces is incredibly obvious. She's less of a Large Ham with her new persona than Rosso though.
- Peek-a-Bangs: Over her left eye. Shown in a flashback something she's had even before she left her village.
- The Tease: In her Storm Sworder persona. She's very flirtatious and often blows her enemies a kiss.
An elderly scientist that is considered to be the foremost expert on Zoids and their history, Doctor D. is initially sought out by Van and his friends in order to see if he can assist them in their quest to find Zoid Eve. It turns out that Doctor D. doesn't know anything about it and initially doesn't seem to stand up to his "genius" reputation either, however the group soon discovers this is all an act and end up helping Doctor D. achieve a dream of making it snow on the mountain where he lives.
Later Doctor D. runs into the group again once they reach New Helic City, where they discover that not only is he a Zoid expert but a scientist of considerable renown within the Republic. Doctor D. refuses to help the Republic fight another war against the Empire, but he does asssit Van and his group in defending the city and then later travels with them briefly as they try to return Rudolph to the Empire.
In Guardian Force, Doctor D. has returned to his position as a scientist working in the field, trying to discover the secret of the Ancient Zoidians along with Fiona and then later becoming a top researcher for the Guardian Force.
Doctor D. isn't a regular Zoid pilot like the others, however he does possess a great deal of knowledge on Zoids and their weapons, even developing new Zoids for the heroes like the Lightning Saix.
- Dirty Old Man: In the Japanese version only he will occasionally make an unwanted advance at Moonbay.
- Eccentric Mentor: Seems rather aloof at times and loves to troll the more hot headed members of the group like Van, but Doctor D. also gives some sage like advice about war every so often.
- Grumpy Old Man: Isn't afraid to pull his age out to complain about the kids today. However he is more optimistic than most.
- Human Popsicle: This is how the group first finds him, frozen solid by an experiment of his trying to create artificial snow.
- Obfuscating Stupidity: In his early appearances Doctor D. acted like a cooky old man opposed to the Zoid genius that he was. He still had shades of this later, but by then his reputation was already known.
- Retired Badass: Until Guardian Force where he comes back to work properly.
- Rocket Punch: He pulls one of these in his special Hazmat suit to save Moonbay and Irvine from Stinger.
- Strange Minds Think Alike: He's the only one who loves Fiona's salted coffee, to the point he spat out a mug of the typical brew in one episode of Guardian Force.
- War Is Hell: This is more or less what he tells the president when she asks him to come back to the Republic and help them defeat the Empire. War is pointless and he is too old to get wrapped up in it again.
Rob Herman is the son of the last two Presidents of the Helic Republic, the former, his father having died and been replaced by the current, his mother, President Camford. Despite having such a powerful and influential heritage, Rob Herman's military career is based on merit and hard work, not relying on his family's status to rise through the ranks. Herman meets Van and the others after the latter destroys a large group of the Republic's sleeper Zoids in self defense. After capturing them and coming to blows, Herman eventually officially hires the group to act as mercenaries for the Republic while they search for Zoid Eve.
After the time-jump of Guardian Force, Herman appears as the Head of Strategic Command and is now a Major in the Republican military. He helps to form a plan against Hiltz's Death Stinger as it advances on the Republican Capital of New Helic City. Later, he is put in charge of the Ultrasaurus by Colonel Krueger. Here, he appoints Moonbay as the pilot and Karl Schubaltz as the operator, and firer, of the Gravity Cannon. By the end of the series, he successfully works his way up to the position of Full Colonel.
- Ace Pilot: For the Helic Republic, at least until Van comes along. Herman is the first person chosen to pilot the Gojulas due to his skill, is able to point out flaws in Raven's attack patterns for Van and is overall one of the Republic's best pilots.
- A Father to His Men: The other soldiers in the Republic greatly look up to Herman, especially those serving under him. It's to the point where he's arguably more respected and popular than his superior officers.
- Colonel Badass: Although it isn't until the end of the series that he becomes a Full Colonel.
- Reasonable Authority Figure: Barring their first encounter, Herman is Van's best ally in the Republican military. If they ever need someone to hear them out, Van will go to Herman.
- You Are in Command Now: Towards the end of the Guardian Force he takes over command of the operation to bring down Hiltz using the Ultrasaurus, a position that was held by Colonel Krueger before he was injured.
Karl Lichen Schwarz (Karl L. Schubaltz)
A Colonel in the Guylos Empire, Karl L. Schubaltz is shown to be an honorable soldier who wants peace, rather than war, between the Guylos Empire and the Helic Republic. He seems to be very duty-oriented and dedicated to his work. Although he is loyal to the Empire and Prince Rudolph, Karl despises Prozen, and would later team up with the Republican forces to defeat him.
- Ace Pilot: Aside from Raven he's the best pilot in service to the Empire.
- Aloof Big Brother: Somewhat to Thomas.
- Pet the Dog: As much as Marcus gave Schubaltz a hard time, he manages to salute his fallen Si C after his death at the Mt. Osa base.
- Reasonable Authority Figure: He is with the Empire but wants nothing to do with Prozen's warmongering. By Guardian Force he's a full time ally.
