B't X (Japanese: ビート・エックス, Hepburn: Bīto Ekkusu), pronounced "beat X" and stylized as B'T X, is a manga series, written and illustrated by Masami Kurumada. It was serialized in Shōnen Ace from 1994 to 2000. The series is set in a fictional universe where science has progressed to the creation of mechanical AI creatures known as Bt's. An anime adaptation containing 25 episodes was aired in Japan between April and September 1996, followed by a second season containing 14 episodes called B't X Neo (ビート・エックス・ネオ, Bīto Ekkusu Neo) which aired between August and November 1997. The anime series never adapted the whole manga series, and included instead a different ending with no conclusion.

The anime series was animated by TMS Entertainment which produced in total, 39 episodes.

Series Overview[edit]


B't X is set on an alternate Earth, where a faction known as the Machine Empire rules a significant large piece of land known as "The Area" in the Gobi Desert. The Machine Empire invests highly in scientific advancements and schools children from an early age to become striving scientists. Mechanical engineering have culminated in the creation of cyborgs and most recently mechanical beasts, powered by human blood, the Bt.

The series mostly takes place in the Machine Empire, but also on Kamui island, where the main characters were born. An island that was created from a crashed meteor and contains a piece of a sun, far underground.

A B't (pronounced "beat" in the Japanese version and "bit" in the English dub.) is the ultimate form of artificial intelligence mechanoid (they are NOT "robotics" since in the Machine Empire, "robot" are considered obsolete terminology that has been replaced by much more modernized terms such as "mecha" and of course the terms "B't" itself) designed for fighting - the B stands for Brain, Blood, Bravery and Battler. They have different forms and powers, usually based on mythological creatures. The B't's source of power is a device called BreakHeart, which is fueled by human blood. Once the BreakHeart is inserted into the B't's body, it creates a link between the blood donor and the B't. A B't is also outfitted with The Guard System, which protects its donor from various dangers and environment changes, such as volcanic heat, the crushing pressures beneath the ocean, or even the depths of space. However, the donor must be in physical contact with his or her B't for the system to work for them. Teppei is able to manifest a suit of protective armor called Battle Gear, through use of the Messiah Fist. This has the additional benefit of activating the usually dormant wings on X's sides, enabling him to reach even greater degrees of speed and mobility.


Teppei Takamiya is the caretaker of a farm located in Kamui Island, north of Japan. His older brother, Kotarō Takamiya, leaves to study robotics in Germany and becomes one of the most brilliant scientists in the world. Five years later, the two brothers reunite at a robotics convention in Mechatopia, China, where Kotarō is to announce his latest breakthrough in artificial intelligence. The convention goes awry when Kotarō is captured by the malevolent Machine Empire and taken to "The Area".

Teppei manages to hitch a ride on his brother's capturer and reaches the Machine Empire, Teppei is attacked by Metalface, one of the Empire's soldiers. Unable to win, Teppei is thrown, bleeding, in the Empire's junkyard. His blood reaches the trashed body of X, who was once considered one of the strongest B't of the Empire, and the disgruntled B't awakens. Faced with unanswered questions and imminent destruction, X reluctantly saves Teppei, and the pair flee the Area with soldiers of the Empire in hot pursuit.

Meanwhile, inside the Area, Kotarō discovers that he has been summoned by another of the Empire's soldiers, Major Aramis, to find a way to stop the ultimate B't - a creation known as Raffaello (ラファエロ) that has begun a terrifying and uncontrollable evolution.

Teppei's main goal is to save his brother, but as he and X venture further into the Area and learn more about the Machine Empire they start to fight for the survival of the human race. On the way to the center of the Empire they gain allies that help them prevail over the guardians of the empire.

The ultimate B't eventually finalizes its evolution and the Machine Emperor appears. Before the emperor can fuse with Raffaello, Teppei and his allies confront him.

Critical Response[edit]

Chris Beveridge of Mania.com reviewed the first DVD volume of the anime series by Illumitoon Entertainment and gave the volume a "C" grade citing that "due to age there isn't a lot to expect" in regards to both audio and visual quality. Beveridge continued to praise the story but also said that it was sometimes confusing. Ilumitoon's decision to use their dubbed script as subtitles for the Japanese audio was heavily criticized as they did not match up.[4]

Other Media[edit]

A B't X themed Pachinko game was released in 2013, with newly recorded music and animation done by TMS.[1][7]

Two toy-lines were produced by Takara in conjunction with the broadcast of the series. The first series consisted of 5 models of four of the main Bt's, and where marketed with the term "Solid Scan". Each Bt had removable armor and an accompanying figure to ride them. A wield-able "Messiah Fist" was also produced with sound-effects and light-up features. The second toyline was produced as action figures and included 14 Bt's with an accompanying smaller figure. 8 non-articulated figures were also released of several main characters under the term "Donor".
