The Spirit Generals In B't X

The Spirit Generals are four warrior generals under The Machine Empire who control the strongest B't. Designated to protect The Area, each of the generals correspond the four cardinal directions east, west, north, and south. The B't that they own represent one of the Four Holy beasts in mythology.

Karen 

Karen is an engineer working for the Machine Empire and one of the original Spirit Generals, where she corresponded the West. She is the first donor of the B't X before becoming the donor of Shadow X. Karen's colleagues frequently describe her as one of the strongest fighters in the Machine Empire. During combat, Karen wields a Sansetsukon or three-sectional staff. Karen is also an able inventor, as she is able to build using scrap metal while on Kamui Island.

• Spinning Thunderbolt: a continuous hit with her Sansetsukon

X 

Once hailed as the strongest B't created by the Machine Empire, X's original blood donor is Karen, the Spirit General of the East and thus obeys only her. X was modeled after the mythical winged horse kirin that rescues people when the world is in chaos. X possesses incredible agility that he can move as fast as lightning. This is further enhanced when he is in Battle Mode.

• Sonic attack: sends out waves that disturbs the hearing of B't and is inaudible to humans.
• Prism of Aura: is a special ability that gives X incredible power and speed.
• Guard System: is a passive ability that allows a B't and his donor to be impervious to elements such as intense heat and pressure.
  
• Shining Wings: an enhanced version of Prism of Aura

Shadow X 

Shadow X has identical form as X but all body is covered in black. It was initially out of control because it was created by using scrap metal, but later became stable with the help of Hokuto and Max. Unlike other B'Ts, she speaks in a rather crushed tone, like a girl and calls X "Brother". She is also good at disturbing the opponent with her agile movements.

• Pretty Mirage: shadow attack with high-speed movement

Fou Lafine 

Fou Lafine is a priest whose base of operations is in a small church near the Machine Empire's capital and one of the four legendary Spirit Generals. He corresponds the South and is the donor of the B't Je t'aime. Though not shown to be as skilled in martial arts, Fou is still a capable fighter. He is also an excellent tactician and has incredible agility in melee combat.

• Funeral Bow: is Fou's primary weapon as well as instrument in playing the violin. The bow has the ability to emit high voltage of electricity enough to reduce a human into ashes.
• Fortune Symphonic: is an amplified version of Je t'aime's Deadly Carol achieved when Fou simultaneously plays a specific type of song on his violin.

Je t'aime 

Je t'aime is the B't of Fou Lafine. Je t'aime's design is inspired by the Vermilion bird of the South in mythology or the phoenix. After her death, Fou is able to resurrect Je t'aime, transforming her into her true phoenix form. In this form, Je t'aime emits a pinkish glow instead of her old vermilion color. With powerful wings and sharp claws, Je t'aime is proved as a capable fighter.

• Deadly Carol: is a sonic attack designed to destroy a B't's mind or main control system. As it puts its target in a trance, it hallucinates angels and skeletons before its mind succumbs to destruction.
• Fortune Symphonic: is an amplified version of Deadly Carol achieved when Fou simultaneously plays a specific type of song on his violin. 
• Resurrection: is the passive ability to be revived after being killed. It was triggered when Fou played the song of the angels on his violin, and results in Je t'aime achieving her true phoenix form.

Ron 

Ron is one of the four legendary Spirit Generals of the Machine Empire. He corresponds the East and is the donor of the B't Raido. He is the highest ranking Military General and the most loyal of the Four Generals to the Machine Empire. Ron is an extremely skilled combatant, an expert in both ranged and hand-to-hand combat. His skills are further reinforced by the spear he wields proficiently.

• Thunder Lance: a spear with dragon decoration.
• Aurora Force Spear: emits energy from the tip of the spear.

Raido 

Raido is the B't of Ron. Raido is an extremely strong and agile B't that he is able to move as fast as lightning. It's design is inspired by the Azure Dragon in mythology. His personality was calm and he follows his donor until the final battle.

• Thunder Cannon: The electric shock emitted from his mouth

Hokuto 

Hokuto, known as Master Doc, is a scientist and one of the legendary Spirit Generals of the Machine Empire. He corresponds the North and is the donor of the B't Max. Hokuto's allegiance primarily lies on his role as doctor that his principles include helping anyone injured, including enemies of the Machine Empire. He is somewhat a pacifist, having little interest in fighting in battle. However, when pressed into combat, he usually tasks his B't Max to fight. In battle, he wields a staff as a weapon.

Max 

Max is the B't of Hokuto. It's design is based on the Black Tortoise from mythology. Max is also an enormous B't that mostly stays underground while Hokuto performs experiments in the laboratory inside her. It's defense are the strongest in the Machine Empire. Her outer armor is made of durable material that it is able underground missiles simply have no effect on her. It can also transform into battle mode and shows the ability to shoot lasers from the gun gate of the whole body.

• Protective Shield: allows Max to emit a layer of energy that fends off enemies around her.
  
• Laser Beam: Shoot a laser
