Bio Booster Armor Guyver - Characters

Characters

Shō Fukamachi (深町 晶, Fukamachi Shō?)

The main protagonist of the series, Shō is seventeen years old and a second-year student at Narisawa high school. He has black hair and a slim build. He fights Cronos more in order to protect his friends and family than from any need to see the enemy brought to justice. Had he not become host for a Guyver Unit, he would have happily continued in ignorance of Cronos. He cares deeply for Mizuki Segawa with the intensity of first love and Tetsuro Segawa, Mizuki's older brother, is his closest friend. As he is the host for the first Unit activated, he is known as "Guyver I".

Tetsurō Segawa (瀬川 哲郎, Segawa Tetsurō?)

A large-framed, chubby third-year student, Tetsuro is Shō's closest friend. He is highly intelligent and can think rapidly when he has to. He is a rabid science fiction fan and the leader of the sci-fi society in the school, which gives him the background knowledge to make numerous accurate guesses about the Guyver armor, Zoanoids and Cronos. He wears his hair short and has glasses.

Mizuki Segawa (瀬川 瑞紀, Segawa Mizuki?)

Mizuki a typical schoolgirl. At the beginning of the story, she has a crush on Agito Makishima, but later begins to appreciate Shō more. She is somewhat short even for a Japanese girl, very slender and wears her hair in a page-boy cut that emphasizes her large eyes.

Agito Makishima (巻島 顎人, Makishima Agito?)

Agito is of medium build and muscular; he is a third-year student at the same high school the others attend, but looks older. Portrayed as an anti-hero, he almost never allows sentiment to stand in his way. He appears shrewd and calculating. At one point a candidate-member of the Cronos Elite, he is now viewed by them as a traitor. Even though he may have activated his Unit before Oswald A. Lisker, the second Guyver, he did not openly appear in his Guyver armor until after Lisker was eliminated and thus he was dubbed "Guyver III". Agito shows a frightening knowledge of what the Guyver can do throughout the series. After the Cronos conquest, Agito leads a resistance organization known as "Zeus No Ikazuchi" or "Zeus' Thunderbolts", as he plans to overthrow Cronos and steal their power (as the god Zeus did to his father, Cronos).

Fumio Fukamachi (深町 史雄, Fukamachi Fumio?)

Fumio is a widower and Shō's father, but almost nothing else is known about him. He is captured and used by Cronos as a guinea pig and turned into a Guyver-killer Zoanoid to entrap Shō. He ends up being killed by Guyver I in battle.

Aptom (アプトム, Aputomu?)

He is a battle creature that hunts down other Zoanoids created by Cronos (except Lost Numbers). By absorbing small amounts of DNA from other Zoanoids, he can replicate their forms and powers, as well as mix the attributes of several Zoanoids in one body. He can regenerate himself even if only small pieces of him are left. Since discovering this ability, he begins killing Zoanoids to take their powers and bio-matter in order to become the most powerful battle creature and becomes a renegade from Cronos. In time, he comes to ally himself with the Guyvers in various battles. Aptom was one of the lost number commandos along with his two compatriots, Somlum and Dyme, who were killed in battle with Guyver I. This leads Aptom to carry a vendetta against Shō. Over time, Aptom questions his own motives and considers Cronos' part in his suffering. He was originally developed as a Zoanoid with the ability to morph into different types of Zoanoids and possess the power of the types he morphs into, but the project failed and he became a Lost Number. Dr. Balcus was interested in Aptom's abilities and carried out further experiments on him. This freed Aptom from the mental control of the Zoalords and gave him the ability to rapidly evolve. Aptom was also gifted with other unexpected abilities, including the ability to regenerate himself even from the smallest remaining piece of his tissue and the ability to clone himself, each clone having its own consciousness. Throughout the story, he has gone through several different chosen forms after absorbing multiple Zoanoids. His human shape is of a muscular man with a distinctive scar that runs down the left side of his face from hairline to jaw. He often dresses in a leather jacket, jeans and sunglasses.

Toshiaki Hayami/Bio-Freezer (速水利章/バイオ·フリーザー, Hayami Toshiaki/Baio Furīzā?)

One of Dr. Odagiri's assistants, he is the sole survivor of that group of scientists that escaped in the relic. The scientists were infected by a deadly virus as Cronos' means of keeping them under control. The only way to escape death is to be supplied with regular shots or to become Zoanoids. The only way to become a Zoanoid and yet not be slaves to the Zoalords is to become a Lost Number. Since supplies of the medicine were running out, they resorted to attempt to becoming Lost Numbers. Hayami was the only scientist that survived the process, becoming "Bio-Freezer". He possesses the unique power to affect the temperature of the environment around him to a certain extent. Aptom finds him and, once he realizes what Hayami is, brings him to meet the Guyvers and their friends. Unfortunately, later on his mission with Sho to save Aptom, he sacrifices himself to save the latter.

Apollon (アポルオン, Aporuon?)

A mysterious figure that has begun collecting Zoacrystals from the deceased Zoalords. He appears to wear a dark armor made from the same material as Guyver's control metal. He has demonstrated mind control, an ability only seen used by Uranus or Zoalord. He also mimicked Caerleon's self division by manipulation of 'unfolded space'. Dr Barcas has speculated that Apollon could be a vanguard of the Uranus. He also appears to be on a tight schedule. He is likely based upon apollyon. Even though the katakana is closer to Apollon, the kanji that is often used beside it is abyss.
