(All characters are referred to by their names in the English dub) •
Van Flyheight - Van is a fourteen year old (at the beginning of the show) orphan of the previous war between the Republic and Empire. His home is the Wind Colony, a village just within the borders of the Helic Republic. Van has an older sister, Maria Flyheight, who is in her late teens. Their father, Major Daniel "Dan" Flyheight, was a pilot with the Republican Army, using a Command Wolf called Zeke. He was killed defending the Wind Colony from an Imperial attack when Van was nine. At the start of the series, Van is chased into some ruins by a bandit named Bol. He then finds two capsules in the ruin. Van opens one to find an Organoid, whom he names Zeke after his father's zoid. He then fights off the bandits in a Shield Liger, which was brought back to life by Zeke. Van then opens up the second capsule, and finds a girl, who he names Fiona. Van then starts a journey to find Fiona's memories, and becomes caught up in a new war, and a plot to take over Zi. Van is a bit dense to start with, but is loyal to his companions and has a good heart. His open nature means that many people are attracted to him, and he enjoys a good challenge. He pilots a Shield Liger, a lion type Zoid that can deploy a shield in front of itself. It later evolves into a Blade Liger, which gives it a pair of laser-edged blades capable of cutting through all but the densest of enemy armor. His favorite food is mentioned as papaya. Throughout the course of the series, Van and Fiona fall in love. •
Fiona Elisi Linette - Fiona is young girl awakened from stasis by Van. She suffers from severe
amnesia, and is unable to remember anything but the name "Fiona". Van gives her this as her new name, and the two set off to discover who she is. As her memories return, it is learned that her full name is Elisi Linette, and that she is one of the last members of the Ancient Zoidian race. Her driving goal is to discover something known as the 'Zoid Eve', supposedly the source of all Zoids' power. Although a bit naive at first (walking past bandits to untie her friends), she matures over time and eventually serves as Doctor D.'s brilliant assistant. While she and Van had somewhat of a rocky start, the two would grow close, and form a bond. It is shown that Fiona and Van develop romantic feelings for one another. Later in the series, Irvine points out Fiona's love for Van. •
Zeke - Zeke is an organoid
dragon, a small Zoid imbued with many powers. Awakened by Van, Zeke is named after the Command Wolf piloted by Van's father. Zeke's primary ability is to fuse himself with another Zoid, increasing its combat potential dramatically. Zeke is able to use this ability to resurrect destroyed Zoids, and to evolve Zoids into more powerful forms. •
Irvine - Irvine is an eighteen-year-old mercenary, and the "tough guy" of the series. Initially interested in capturing Zeke, he later joins Van, Moonbay, Zeke, and Fiona after losing this desire. Although cold-hearted in appearance, Irvine shows a soft side on more than one occasion. He is a skilled pilot, who uses a modified Command Wolf with a powerful long-range rifle. When his Command Wolf is severely damaged, its combat data is transferred into an experimental Zoid, the Lightning Saix, which uses extreme speed to overwhelm the opponent. While he wears an eye patch, he has full function of both his eyes, and uses the eye patch as a camera. •
Moonbay - Moonbay is a trader, who often smuggles weapons using the Gustav, an armored insect Zoid capable of pulling 250 tons of cargo. She is considered to be a free-spirited individual, who is not afraid to speak her mind. Although she appears greedy and selfish initially, Moonbay is a good person. She does like to sing, although she rarely stays on key. •
Raven - Raven is the top pilot of the Guylos Empire, adopted by Prozen after his parents, Zoid researchers, were killed by the Organoid Ambient. He is selected for his prodigious piloting abilities, which are complemented by the Organoid, Shadow. Raven is extremely anti-social and reserved, and holds a deep dislike of all Zoids. He considers Van to be his rival, and swears not to rest until Van has been killed by his hand. Raven pilots a Zaber Fang, which is destroyed in a battle with Van. He then pilots a Genosaurer which is destroyed by Van in another battle. It is replaced by a prototype Genosaurer, which later evolves into the powerful Geno Breaker. •
Admiral Gunther Prozen - Gunther is the main villain of the series. He is the Regent of the Guylos Empire, an Admiral in the Guylos military, and the second in line for the throne of Guylos. Prozen arranges for Prince Rudolph, next in line for the throne, to be kidnapped and assassinated so that he can seize power after Emperor Zeppelin's suspicious death. He plans to use the Death Saurer to take total control of the world. He is believed to be killed after his Death Saurer is destroyed, but is shown to have survived as the Dark Kaiser. •
Hiltz - Hiltz is an Ancient Zoidian with a red Organoid named Ambient. His driving goal is to restore Zoidians to power, even if all humans have to die to do so. He pilots the Death Stinger and later merges with the Ultimate Death Saurer. Hiltz is the main antagonist of Zoids Guardian Force, and arguably the entire series as his arc is tied to Fiona's past and the quest for the Zoid Eve. He is killed in the final episode when Van is fired through the gravity cannon and penetrates the Ultimate Death Saurer. •
Rease - Rease is an Ancient Zoidian with a blue Organoid named Specula. She pilots a Double Sworder, and later upgrades to an advanced "Psycho" Genosaurer which was developed based on the data of Raven's Geno Breaker. She and her Organoid both possess psychic abilities, and she often uses psychological warfare and mind-control to disable her enemies. While she is first an ally of Hiltz, she changes sides after she finds out Hiltz had been using her all along. She appears to have some feelings for Raven, as she does help him come to terms with his past. •
Dr. D - Dr. D. is a self-confessed mad scientist once employed by the Republican Army as a Zoid researcher. He is considered Zi's foremost expert on anything Zoid or Organoid related, and enjoys hanging around with Van and his group. His attitude and demeanor irritates Van and Irvine, but D.'s knowledge comes in handy on several occasions. •
Prince Rudolph Zeppelin III - Rudolph is the grandchild of Emperor William Zeppelin. Rudolph is placed into the care of Van by Rosso and Viola, former waste gangsters turned bodyguards. Van agrees to help return Rudolph to the Guylos Empire capital, Guygalos, and to teach the boy how to pilot a Zoid properly. Although Rudolph's identity is initially kept hidden from Van and his friends, Doctor D. soon reveals the truth about the Crown Prince. Rudolph is an eager, friendly person, who wishes to be able to emulate Van in piloting skill. Rudolph is quite naive and prefers reasoning over fighting, even with Raven and Prozen. He also deeply cares for the Guylos Empire and hates seeing others around him hurt. •
Karlton "Karl" Lichen Schubaltz - Karl is one of the Guylos Empire's greatest Zoid pilots. Karl is an honorable fighter, and wishes to see peace between the Republic and Empire as opposed to total destruction of both sides. He has a younger brother, Thomas, who doesn't appear until Guardian Force. He both loathes and distrusts Prozen, though he respects the command chain, and so he reluctantly follows orders. Initially a major, he is later promoted to the rank of colonel. Karl Schubaltz pilots the Dark Horn and the Iron Kong, as well as a custom Zaber Fang. •
Thomas Richard Schubaltz - Thomas is the younger brother of Karl Schubaltz, and pilot of the Dibison. He excels at technical tasks, and is the creator of the BEEK
AI unit, which can be installed into a Zoid, and communicates through a series of beeps. When he first meets Fiona, he develops a huge crush on her. This serves as somewhat of a gag, as Thomas is shown to compete with Van for Fiona's feelings (though neither Fiona nor Van pay heed to this). •
Robert "Rob" Herman - Robert is the commander-in-chief of the Red River Unit at the Red River base bordering Imperial territory. He is also the son of both the Republic's former and current Presidents, but he is a confident soldier who does not appear to rely on the influence of his family in order to benefit himself. Instead, he prefers to perform his duties and to earn his rank in the army on his own. In fact, in one of the episodes, it is hinted that he is so detached from his familial ties that he has not called his mother, the current President of the Republic, "Mom" in several years, instead addressing her by her proper title as any other soldier would. The Zoids he has been seen piloting most often are a Pteras and a Gordos. He has also been seen piloting a Gojulas and a Shield Liger from time to time. • '''DJ O'Connell''' - DJ is the second-in-command to Robert Herman, and most commonly pilots a Command Wolf and Pteras. His loyalty is a notable character trait, as he appears quite upset when Herman is missing in action, leading him to accept the assistance of Van, Moonbay, Irvine, Fiona and Zeke (for a price). ==Zoids==
