Teppei got out of Max and confronted Balzac and his b't Savanna. After attacks from the Crazy Ants and the Laser Slayer, Balzac was defeated. Teppei continued on but was blocked by Fou.

He decided to take a chance when suddenly a fire appeared.

Episode 20 - Life! Break Heart

Teppei woke up to find X's pieces scattered all over a room! He was shocked to see X's severed head. A voice told him to be quiet. It was the Spirit Knight Hokuto. Teppei was inside Hokuto's b't Max. Teppei got dizzy, the effects of Hokuto's drugs.

Hokuto was also on his way to the Area when Max was attacked by missile and acid bombs. Underground b'ts called Crazy Ants were the one responsible for the attack. Hokuto ordered Max to go to source but found nothing. Then lasers appeared and trapped Max. These came from Balzac, the one in charge of this particular point in the Area.

It was time. Teppei woke up and Hokuto presented to him... X. X had been scrap but fortunately his brain was still in order that's why Hokuto was still able to save him. X had a new body and an improved Guard System. Hokuto gave Teppei the Break Heart, with blood filled from Teppei. Inserting that into X, he was revived!

Episode 19 - Desperate! X's Death

As Teppei continued on his way, he was attacked by Karfuss's troops. Normally they would't pose too much of a threat, but X was running dangerously low on power. The spy troops got X but suddenly the Dark Knights and its leader Mira appeared. With one sweep of his lance, Deadly Flash, Mira killed the spy troops.

They attacked and it was an effort to defeat two Dark Knights. Teppei wanted to escape but X said its really impossible to do that as Mira would eventually catch them up. Fighting took a toll on X and after defeating Mira, he said his finaly goodbye to Teppei. The Shadow Knight appeared and pushed them to a crater.

Episode 18 - The Dark! Fear of the Underhell

The keeper of this horrible place is Marcellus and Amigo. Kotaro befriends Professor Nietsche but it was short lived since Nietsche died after suffering so much. Before he passed away though, he gave Kotaro Raphael's blueprints. It was full of numbers that was so difficult to figure out. Kotaro decided to fight his own battle though, much as his brother was doing his best to rescue him.

Teppel meets up and finds out about the Dark Knights. They were out to get Fou, but Rai met Teppel and decided to kill him also. Though weak Teppel and X defeated Rai's Thunder Stinger.

The god of death was strong, he wielded a scythe and rode on a huge bat b't. Teppel could not at all get near him. The god of death had Teppel cornered but Maria saved him from the scythe. But she was hit and it turned out that she also had a cybernetic body. Maria was thankful that she could finally rest in peace and requested Teppel to save her brother. The god of death was her brother.

Teppel was so bent on defeating the god of death and pushed X to the limits. X's wing was broken and was severly damaged by the Devil Slain Crusher attack. X protecting Teppel collapsed. On the ground bats came to converge around them but suddenly they also collapsed. The sound of Je t'aime approaching was enough to have them scared and leaving. Teppel thought Fou would save him but no. Fou bluntly told him it was Teppel's fault why X had fallen, he just treated X as a machine and the glory that was X could never be anymore. And he left.

Teppel still had the god of death to deal with and X, using his last ounces of strength, offered to help Teppel again, with one last move. Teppel this time let X go first and with that, performed the Aura of Prism. They shone so brightly that even Fou and Je t'aime had to stop and look at it. With that, the god of death was defeated and so the brother of Maria was eventually freed and rested peacefully together with his sister.

Episode 14 - Tragedy! Maria, the Girl Who Lives in the Graveyard

Next Area point was a graveyard. A huge tree reminded Teppel of their tree house in Kamui island, but to their dismay, the tree was littered with hundreds of hanged skeletons. A girl named Maria appeared in the graveyard, lighting candles she said for her friends who had lived for 300++ years. She strongly warned Teppel to go back if he valued his life. This was the area of the God of Death. Teppel could not be dissuaded. True enough, b't bats appeared and attacked Teppel and X. X used a weak sonic attack to confuse them and Teppel destroyed them. Then the real danger came.

Episode 13 - Buddy! The Bond of a Passionate Soul

Kaos was really good, enough to warrant him as a legend. Sadly, he says, X was also a legend, but because Teppel was a weak one, X's status is even lower than the lowest ranking b't of the Empire. Kaos challenged Teppel to show him his dream and if he didn't he might as well be dead. It was a difficult battle for Teppel but he eventually managed to awaken his inner strength and show Kaos his passionate soul.

Episode 12 - Formidable Enemy! The Warrior Kaos!

Fou and Ron were battling it out when a strange energy burst from underground. It came from Max, Hokuto's b't. Hokuto tossed a canister to Ron. Inside it was a small sample of b't Rapahael. It was stored degrees way below zero to slow down its growth, and Hokuto explained to Ron what Karen discovered five years ago.

Meanwhile, Teppel found a forest in the middle of the desert. After resting a bit, they went on their way when a scarab beetle b't attacked them. Its name was Lamu and belonged to the legendary warrior Kaos. Lamu attacked them with his Golden Storm and both fell in the river.

Ron's strength and was defeated. But Ron spared Teppel's life, as he had more important things to do.

Episode 10 - Chase! Metalface Counterattacks

Teppel was still weak from Kaimura when Metalface and his b't Madonna arrived. They forced Teppel and X into Hell's Valley, a place very dangerous to b'ts. Winds in the area create sound waves that cause vibrations and destoy metal. An unknown person came to Teppel's aid, restoring X and giving him medicine for the after effects of the Evil Flower.

That person's name was Professor Zaji, the same person who had helped Karen escape from the Area. Metalface again appeared and attacked Zaji. It was revealed that Zaji also had a cybernetic body.

Episode 09 - Fear! Evil Flower

Teppel was able to break free from the illusion by realizing that the monter's red ribbon is the one he tied himself on X before and wa able to get out of the lake. Teppel went to Kamiura and struck him but to no avail as Kamiura was still using illusions to dodge Teppel's attacks. In return, using the power of the Evil Flower, Kamiura sought to destroy Teppel's mind.Meanwhile, Mirage was battling X. The pollen damaged X's control system so it wasnt functioning properly and was hapless to her Death Flap. But both heroes eventually defeated his respective oponent.

Episode 08 - Magnificent! Dazzling Soldier Kamiura

The oasis is located on the next point, being guarded by Kamiura, the Empire's strongest illusionist and his b't Mirage. X sensed something ominous in the oasis but Teppel argued that it's the only way to save Gaku. They still dove into it. Little did they know that they had already inhaled the Evil Flower's pollen and it was just only a matter of time before they will be destroyed.

Kotaro saw a kid waiting for him. He thought he was the Emperor but we was mistaken. The kid's name is Misha, and beside him was a little girl named Nisha. They were merely representatives of the Emperor, and he decides if a person's worthy of seeing the Emperor.

Episode 07 - Frightening! The Mystery of the Machine Emperor

Captain Hook is a person who doesnt give up easily. Using his Hanging Rod, he was able to catch Teppel again. Gaku, the boy who controlled Big Rock, decided that he isnt afraid of Captain Hook anymmore and decided to help Teppel. But Capt Hook called Groupie again and nearly had Gaku eaten before Teppel again rescued him. This time instead of going inside Groupie's stomach, Teppel used the Messiah fist to chop Groupie's body. This time, the b't really had it.

Unguarded, Capt Hook caught Teppel and sent electric shocks to Teppel. Using maximum power, Capt Hook used his Electric Lightning to burn Teppel to death. Teppel broke free by shorting out the attack and sending it back to Hook.

Gaku came to Teppel but collapsed because he had inhaled too much acid from Groupie. They have to wash that acid off to save him and went on to find an oasis.

Meanwhile at the Area, Kotaro found the room full of toys. A bunch of them, tanks and missles attacked him, but a voice told him it was just teasing him. He proceeded into a room and what he saw surprised him.

Episode 06 - Fear! The Watch Man, Pirate in the Desert!

Teppel encounters Big Rock in the first point. But in turned out to be just a giant recylced robot. The real person in charges of the Area was named Captain Hook with a giant b't named Gruppy.

Teppel defeated it by going inside and using his Break On technique to create a hole in the b'ts interior.

Episode 05 - Departure! Desperate Battle Road

The show starts with Teppel finding out that his brother Kotaro already gave allegiance to the Machine empire and had allowed the empire to make his body into a cybernetic one. And then Teppel woke up screaming, to the amusement of the orphans. He found out that he had been out for 2 days and that Fou had taken him in and Karin attented to his wounds.

Teppel rushed out to the church to look for X and he found him lying on his side immobilized. Fou took out the master control from X and Teppel rushed to get it from him. Only this time a claw came out of nowhere and snatched it.

It was from Karfuss and his two other hencmen riding on black crows b'ts. He said he was gonna report Fou's betrayal to the Emperor, seeing that Teppel and X were not really destroyed. They got off but Je t'aime pursued them and got Karfuss and a henchman. Teppel took care of the last one.

Karfuss was begging forgiveness from Fou but being the sneaky person that he is, took hostage one of the orphans. Fou couldnt do anything as he was being attacked by Karfuss's claws. But then Teppel came to Fou's aid and destroyed one of the claws, allowing Karin to get the other orphans into the safety of the church. Fou had now the opportunity to destory Karfuss, using his Funeral Bone.

Even after dissuading Teppel, Fou still can't stop him from rescuing his brother. They left and Fou can only watch as Teppel and X rode on, straight to the security points of the Area.

Episode 04 - Appearance! The Legendary Spirit Knight

Warrant officer Karin rushed to the church to call on Fou Rafine, one of the four Spirit Generals, with an urgent order from the Area. She told him that X had been revived. Because of this, Fou had to momentarily stop the church service with orphaned kids.

At the Area, it was shown how Rafael, the Empire's strongest b't devoured animals and even humans! Major Aramis recounted how they make b'ts. The designs and the materials are from the Emperor and they manufacture it. But when they got Rafael, it was just like a small egg. But then it fed on a mosquito and since then it has been growing after every meal. The Empire is worried that if Rafael continues with this, he'll eventually swallow the whole earth. But still Professor Takamiya refuses to help the Empire, saying its an evil entity.

Back in the desert Teppel continues with his journey towards the Area. However, Fou found him and attacked him. Though Teppel already released X, X still came back to help Teppel because Karen trained him and for X, that's good as Karen riding him. Fou, on his b't Je t'aime had the upperhand on Teppel and X, stunning them with Je t'aime's Deadly Carol. Teppel had an idea to shut down X's audio senses and ride him in manual mode. However, as they were able to finally get close to Fau, it turned out that Fou is also a strong fighter with a strong weapon too, the Funeral Bone.

Fou was about to deliver the final blow, but something in him hesitated: How was Teppel able to control X even if he wasn't the original donor? Fou let go of Teppel.

Episode 03 - Confrontation! The Machine Empire

X still refuses to obey to Teppel's will, because he isn't his original donor. Teppel decides to make X think otherwise. But being a stubborn b't he flies away but Teppel still managed to get on x's back, stating that wherever X goes, he'll go. X went to the Earth's core, full of magma. Teppel shouted at X to stop but he still continued. Surprisingly Teppel is still alive. Next they went to depth's of the ocean, where pressure can instanly destroy a human. Even there, Teppel can breathe. Lastly, they went out of Earth into space. There X explained the Guard System, so long as the donor is with his b't he stays protected.

Flashback to the time that Karen trained Teppel in Kamui Island. Karen found out that Teppel is the brother of famed boy genius Kotaro. Teppel learned that one cannot be strong if its just to protect oneself, one can be strong if its to protect the important ones in their life. After five years, Karen deemed Teppel to be ready and gave to him the Messiah Fist.

Major Aramis also told Kotaro that the Empire is being protected by four Spirit Generals, each one having a powerful b't.

Episode 02 - Rebirth! The Sun Battler

Aramis explained further the concept of the b't. Aside from having a brain of a human powered by the human blood, b'ts are very brave in battle. Kotaru realized that b'ts are only built for this purpose and strongly refused to join the Empire.

X pushed Teppel away when he tried to go near him. A still surprised Metalface said that its still impossible that X was revived because he fully knows that Teppel is not the orignal donor. But Metalface's body had been damaged and he collapsed. Madonna challenged X to battle but X told her to assist her master instead. X flew off but Teppel caught him by the tail and held on while climbing on X's back. Teppel passed out and a flashback ensured.

In that flashback it was revealed that Teppel had found Karen unconscious and he brought her to a secret cave only he and his brother knew. Shortly after that Metalface came to ask him if he had seen a woman around. Without warning, Metalface struck Teppel's horse Maple and it died instantly.Teppel of course got mad and denied seeing anyone and even if he did, he would not tell. Getting nothing out of him, Metalface also struck Teppel and left him bleeding to death in the snow.

Karen got out of the cave and saw Teppel. She felt sorry for the kid but she had to move forward. But something in Teppel made Karen go back, his strong persistence and the light that shines out from him. In exchange for saving her life, she transfused blood into him and he was also saved.

Back to the present, Teppel and X were still fleeing from their pursuers. But both eventually got tired and decided instead to face their attackers. Teppel brought out a disk that Karen gave to him, inserted it to X and shouted "Battle Gear On!" This resulted in a transformation of both Teppel and X, Teppel putting on armor and X opening up his wings. Together with the Messiah Fist, they defeated them.

Episode 01 - Miracle! The Revival of B't X!

Brothers Teppel and Kotaro Takamiya are reunited after 5 years in a robotics convention where elder brother Professor Kotaru, considered as the top scientist in the world of robotics, was the special guest. A robot masquerading as an usherette tried to kidnap Kotaro. Fortunately, Teppel arrived on time and destroyed the robot using his Messiah Fist.

Major Aramis and Lieutenant Metalface also came in the scene. Using a giant robot that looked like a praying mantis, they released poisonous gas in the room where Profesor Takamiya was discussing and instantly killing the audience. Teppel barged into the room but was too late because Aramis and Metalface already kidnapped Kotaro. Using the Messiah Fist, Teppel was able to hitch a ride with the gigantic robot into the Area, the headquarters of the Machine Empire located somewhere in the Gobi Desert.

Here the brothers are yet again separated. Kotaro was taken inside the fortress and Aramis showed him the Empire's most precious treasure, the b't. A b't is a robot who can think and act like a human but with a major difference... it's powered by human blood. It will only obey the first person who donated blooed to it and will only take orders from that person and nobody else.

Meanwhile, Teppel was thrown off the gigantic robot by Madonna, Metalface's B't. Metalface wounded Teppel with his Cybernetic Lance and bragged about his cybernetic body created by the Empire. Teppel didnt find this amusing and struck Metalface. Madonna came to her master's aid and had Teppel in a death grip. Then Madonna sensed an energy reading coming towards near them and suddenly a b't appeared. To everybody's amazement, it was X.
