Beyblade Wiki

This is an article about the anime character. For the manga counterpart of the same name, see here.

Doji (大道寺, Daidouji) is a recurring antagonist in the Metal Saga. Though not being the primary antagonist of Metal Fusion or Metal Fury, he is still a major antagonist, and would later become the main antagonist of Shogun Steel. He is the only major antagonist in multiple seasons.

He was an enemy of Gingka Hagane and the former leader of Dark Nebula who had Ryuga. He used to own Dark Wolf DF145FS before it got broken. Doji seeked the power of the "Forbidden Bey", Lightning L-Drago 100HF.

Doji and Ryuga were the ones who invaded Koma Village, Gingka's hometown, and stole the Forbidden Bey Lightning L-Drago from it. Being the head of Dark Nebula, and having Ryuga on his side, he arranged the Battle Bladers tournament in order to give Ryuga more power so they could eventually rule the world. This plan backfired when Ryuga used the dark power of L-Drago and attacked Doji; sucking most of the life energy within him for L-Drago and left him waiting for death.

Despite this major damage to his health, Doji would not give up and started to wear a long coat that covered his body, a top hat, an artificial leg, and a walking cane due to the attack he suffered at the hands of L-Drago. As a result, he found Rago and the Nemesis Bladers and brought them to Pluto as he made his ultimate return in Beyblade: Metal Fury, only to die once again due to Ryuga's new Special Move.

Doji finally returned as the true main antagonist of Shogun Steel, but this time, he was apparently revived by Merci. He was converted to light energy stored within the Hades computer system and being placed in a machine known as Robo Doji. His new form poses as a threat to the WBBA and the future of Beyblading. In addition, Doji is the secret mastermind behind Team Garcias's organization: DNA, which stands for Dark Nebula Again. This is all part of his plan to bring back Dark Nebula.


Doji appears to be a wealthy businessman. With a pair of hexagonal shaped glasses, a purple suit and a red tie, he passes off as an intelligent, wealthy young man. He keeps a comb in his chest pocket and is seen in many episodes using it only to comb his golden streak in his hair, which he appears to love.

In Metal Fury, Doji's appearance changes considerably. Instead of glasses, he now wears a monocle while his other eye is covered by hair and has a scar passing through it. He now needs a cane for walking. His clothes seem more old-fashioned than his previous ones - he wears a long grey coat and a frilly white cravat. His hair has changed from black into a lighter grey.

His hologram looks in the Shogun Steel series shifts back to the first season design, implying this is how he still wishes to be seen.


Doji is a person who never really gets serious even if his enemies were strong such as Gingka. He is also a person who doesn't like to show his real power, especially not to children such as Kenta. Doji is extremely cruel, often punishing members of the Dark Nebula by "feeding" their power to Lightning L-Drago 100HF. He is never one to give up on his goals and desires, as he uses his intellect to get ahead of his enemies. He always speaks in a polite manner, even to his enemies, but there's no mistaking the arrogance in what he says. He'll frequently access people as 'my friend' in a condescending manner. Generally, he appears to never accept people as being on his level.

As shown in Metal Fury, Doji has a habit of taunting those who oppose him. In episode 141, he even goes so far to anger Ryuga by making note of him helping Gingka, as well as degrading him to a mere pawn in Hades Inc's plan. It's a form of manipulation, as he clearly knows this will cause Ryuga to immediately stop any cooperation with the other Legendary Bladers. Doji appears to take great enjoyment of taunting Ryuga, as he laughs hysterically at the Dragon Emperor's reactions. He has even done this to Gingka back in Metal Fusion when he "awakened" Lightning L-Drago.

Socially, Doji keeps his distance (Yu was the only one who had the potential to form a friendship with him.) He only associates with those who can be of use to him. Powerful bladers like Ryuga and Rago deserve the upmost respect, in his mind. Although Doji doesn't get close to others, he has the ability to "play others' emotions like a piano". This is shown in episode 3 of Metal Fusion when he agitates Kyoya to the point where he bets on his free will. He also does this in Metal Fury to Ryuga in order to mess up the Zeus Barrier.

In private, he has a conflicted relation with his own interests. He claims to 'hate cacti so much that he can't think about anything else'. The true reason for this, as Doji further describes, is that they are so prickly that he can't hug them. This sort of utter obsession with things he can't have seems to be a large part of his character motivation. In the anime version of Zero G, he is especially driven by this - given he is physically dead, he can't have any form of physical sensation which he now misses terribly. In addition, he wanted to use the Synchrome System to break the WBBA and make his foes suffer as revenge for his death.


Not much is known about Doji's past. The only scene involving Doji was the event in which Ryuga obtained the "Forbidden Bey", Lightning L-Drago 100HF. Doji most likely found out where it was and lead Ryuga to Koma Village - The Beyblade Village where Gingka grew up in . He was seen helping Ryuga reach the Bey by launching his Dark Wolf against the traps and even Gingka's father, Ryo Hagane. It was most likely his decision to place Ryuga in a coma until Lightning L-Drago 100HF could awaken to it's full potential. At that point, Doji was loyal to Ryuga as he wanted to train him and L-Drago. However, it was revealed later that raising Ryuga was only meant for using him for Hades Inc's grand plan.

Beyblade: Metal Fusion

Doji challenging Kyoya to a battle.

After Gingka Hagane left Koma Village on his quest, Doji kept a low profile as he waited for L-Drago's power to awaken. After hearing that Gingka beat Kyoya Tategami in Metal Tower. He arrived at his hideout, dragged him and his friends to a foggy area and began making small negotiations with him and his gang the Face Hunters. Refusing to make an agreement with him without a fight, Kyoya challenges Doji to a bey battle, promising to do whatever he is told if he loses. Benkei and the Face Hunters battle Doji to test his strength. But when he takes out his Dark Wolf Bey, Benkei remarks that it's "rare". Even with Doji outnumbered by a few opponents, his vicious Wolf easily takes Benkei and the others down. Kyoya battles Doji next and uses King Lion 100 Fang Fury to get some good hits on Wolf. Despite the weather conditions being in Kyoya's favor, his lack of skills ultimately leads to his defeat, forcing him to keep his promise. Doji was the one to offer Dark Bull H145SD, Benkei Hanawa's current beyblade to him in order to defeat Gingka, and that defeating Gingka is the only way to get back Kyoya until Doji says so. Benkei however fails to beat Gingka after he trained with his new Beyblade which Doji doesn't find surprising. Doji later puts Kyoya to his limit in intense physical and mental training such as beating Training beys and a hologram Gingka while Doji watches impressed with his progress. Doji later tells Kyoya on a airplane ride that while he completed the training program with amazing results, he still was not strong enough to beat Gingka. He then sends him to Wolf Cannon to find the fangs of the heart needed to beat Gingka. He even uses his Ai Merci to gather data on Gingka so he can be defeated which he succeeds in gathering data for the Dark Nebula. After Kyoya's training is complete he sends him to the city to challenge Gingka which goes both ways and it looks like Gingka may lose which pleases Doji. However in the end Gingka wins.

After the battle Doji shows up, revealing himself to be behind Kyoya's training and his new powers. Gingka challenges Doji to a battle but Doji denies the challenge and mentions his corporation Dark Nebula Organization and says that Kyoya's training was less than adequate and viciously attacks Kyoya at the scene while Kyoya's Leone was crying; injuring Kyoya badly and cracked some parts of Leone. Benkei quickly rushed to him in worry while Gingka got angrier because of what the executive of Dark Nebula (Doji) did. After distracting the group with a large metal disc rolling and stopped on the ground without any casualties, both Doji and Gingka disappeared into the night. He invites Gingka and his friends to the Dark Nebula Castle, where he awaits them and studies Gingka's data. Once they arrive they are stalled by Defenses put up by Doji so Gingka and co. cannot enter the castle. Gingka and co. and Doji are surprised at the site that Kyoya has arrived in order to help them. Gingka and co. manage to breakthrough by combining their special moves. Doji and Merci have prepared traps to stop them, but they still succeed in passing by all of Doji's tasks and challenges including taking down Dan and Reiki Sodo. Gingka reaches Doji and challenges him to a battle as revenge for his father after refusing Dojis offer to join Dark Nebula. A battle sparks between the two, causing Ryuga to awaken from his coma. Doji loses, but this fails to faze him. He oversees Ryuga and Gingka's battle, knowing that Storm Pegasus 105RF is actually feeding power to L-Drago. Gingka loses, and Doji reveals that it was Gingka himself that helped L-Drago awaken, causing the boy to fall in shame.

Ryuga's awakening causes Doji to appear less often, usually spending time in his office overseeing Ryuga's battles with Dark Nebula Bladers. He did, however, find Yu Tendo, hired him after he lost to Ryuga in the desert and sent him off to the Survival Battle, which he wins in by beating Gingka and Kyoya. As a reward for winning the Survival Battle, the WBBA grants whatever wish the winner chooses to grant. Yu, as instructed to do, asks for Battle Bladers to become possible. The crowds shout in approval for this wish. As Blader DJ willingly agrees to this, Doji shows up in a helicopter, revealing that not only will his organization sponsor it, but he will also become Master of Ceremonies, granting him the power to do whatever he wishes with the tournament. Both him and Yu agree to only allow bladers with 50000 beypoints entry into the tournament. He then explains that battle Bladers will make everyone know Ryuga as the king of all bladers once he wins the tournament. After making their announcement, Doji, Yu and Ryuga take their leave, despite Gingka's great disapproval. On the helicopter ride back, Doji reveals to Yu that he didn't think Battle Bladers would have been possible without him. He didn't believe there were worthy enough bladers to be Ryuga's food. He then explains that when Ryuga wins Dark nebula will unleash a dark power on the world controlling everything.

Doji spends all of his time in his office, sometimes with Yu as they await the beginning of Battle Bladers. During this time, he recruits many new members of Dark Nebula, including Tsubasa Otori, Tetsuya Watarigani, Tobio Oike, Ryutaro Fukami and Reiji Mizuchi. He makes use of a machine to upgrade light wheel beyblades to metal wheel ones. Examples of this are Dark Gasher CH120SF and Evil Gemios DF145FS. He sends his bladers to many challenge matches to study Gingka's gang. One victory came when Yu and Tubassa beat Hyoma and Kenta, while Tetsuya beat Benkei at a challenge match, but lost to Gingka. He later sends Yu, Tsubasa Dan Sodo and Reki to a challenge match to find new bladers to recruit. However, in the end Dan and Reki are eliminated after losing to Kenta and Yu and Tubasa lose the battle royale.

Later Doji learns that Gingka lost his beypoints which concerns him as Gingka may not get to be food to Ryuga. He punishes Tetsuya for stealing Gingka's points by locking him a room. During that time Tsubasa gets caught after attempting to send much needed information to Gingka and his friends. Doji and Yu orders the Dark Nebula to attack. He defeats all of the Dark Nebula's lower class bladers such as the Kumade bros, Dan, Reki Tetsuya Watarigani and Dark Nebula Bladers. but Ryuga shows up just in time to battle him. Doji believes that Ryuga will win. Just when Ryuga performs him final spin move, the mysterious Phoenix saves him and escapes. This causes Doji to become agitated but interested in the masked blader. He then orders Tobio to battle in a challenge match and beat Gingka which he fails to do. He even tracks down his hiding place, only to find he's too late. However, his findings give him an idea of who exactly he is behind the mask. He and Yu later go to Koma Village to investigate but find nothing of use to them with Doji telling Yu to stop playing with Hokuto.

Doji at Battle Bladers overseeing Reiji.

Battle Bladers begins, giving Doji an active role again. He kick starts the tournament with an opening speech, leading to Benkei Hanawa and Tobio Oike's battle. He later gets disappointed in Yu for losing to Ginka and pleased at Reiji Mizuchi for beating Hyoma. After the first round, Doji, unsatisfied with the Dark Nebula's string of defeats, sends the losers to Ryuga to become food. Yu, among these, battles Reiji for a "warming up". Flame Libra T125ES and Yu himself suffer great damage, but he manages to escape, surprising both Doji and Reiji.

Doji challenging Kenta to a battle.

Before the 2nd round begins The Master of Ceremonies exercises his right to change the order of who battles who, which angers Gingka and his friends. Anyone failing to follow his rules will be disqualified, he says. From there until the semi-finals, he oversees the battles getting pleased with Ryuga and Reiji for crushing Kenta and Tsubasa. He also says that Ryutaro will have to battle Reiji for losing to Gingka.

Before Reiji and Gingka's battle in the semi-finals, he successfully captures Yu which makes Kenta Yumiya and Hyoma try to stop him, pleasing Doji knowing he can give more food to Ryuga. As expected, the two arrive, causing Doji and Dark Nebula bladers to take action. Kenta reaches a room with a crystal chandelier, where he meets with Doji. They battle for only a short while, as Kenta was using a stolen light wheel bey. Right when Wolf goes for the kill, Hyoma's Rock Aries ED145B sends Dark Wolf away, but this only starts a battle between Aries and Wolf. Doji, knowing that Hyoma doesn't have as much power as he started with, tires him out. Just when Hyoma is ready to give in, Kenta launches his greatly damaged Flame Sagittario C145ES at Dark Wolf, placing a chip in between the metal wheel in the process. Doji, seeing this as an act of desperation, performs his spin move on both beys. He defeats both Kenta and Hyoma, who are on the floor.

Right before he goes to take their souls to Ryuga, Phoenix interrupts, appearing out of nowhere. This angers Doji greatly, for this was the second time Phoenix interfered. Despite this, Doji calmly and confidently challenges him to a battle, determined to defeat him once and for all. Strategically, Doji doesn't show his true power until Phoenix proves that he will require it. He sends both Phoenix and his beast under a black hole of darkness. When he almost had them finished, Phoenix reappears out of the hole, sends Burning Fire Strike straight for Flame Sagittario C145ES chip wedged in the Dark wheel and cracks Wolf's facebolt in the center. This sends Doji across the room and the impact sends the crystal chandelier on him.

Doji losing his soul to L Drago.

Later, Doji breaks free from the crystals. He becomes crazed for Ryo Hagane's defeat, claiming that he will defeat him, even with his damaged Dark Wolf. On his way out of the Dark Nebula building, he runs into Ryuga. Ryuga says he has no need for frightened people as Doji was concerned that he wasn't powerful on his own to defeat Gingka. Unfortunately, Ryuga thought Doji didn't think he was powerful on his own and launched L-Drago out as revenge. Doji launched his shattered Dark Wolf, and Doji loses. L-Drago then takes all the power out of Doji, his soul included. After L-Drago was completely defeated, Doji's soul, like everyone else's souls, was placed back to his body.

Beyblade: Metal Masters

Even though Doji didn't appear in metal masters (except for flashbacks). It was revealed by Dr. Ziggurat that Doji was sent to retrieve Lightning L-Drago 100HF, raise Ryuga and release their power to take over the world. Dark Nebula was created for the sole purpose of using Ryuga. Dr. Ziggurat was behind the entire operation, revealing himself to be Doji's boss and Dark Nebula's real owner, HD Academy. it was also revealed that Ziggurat was also the mastermind behind Doji's actions in Beyblade: Metal Fusion, planning to use L-Drago for his experiments, which finally resulted in an alternate energy source he dubbed Spiral Force, powered by the bey Twisted Tempo, which was based on both L-Drago and Pegasus and wielded by Faust.

Beyblade: Metal Fury

After being absent for one whole season, Doji finally returned in Metal Fury but in a damaged state due to his assault by Lightning L-Drago. Doji found Rago and the Nemesis Bladers and brought them to Pluto at the mystic ruins, to show his loyalty to Nemesis. It was later revealed by Doji that both him and Ziggurat were members of the cult all along and both their search for L-Drago and Dr. Ziggurat's Spiral Force were part of the cult's plan to revive their god to destroy the world and recreate it in their image. When the legendary bladers fought Nemesis, who was still in his prototype form, Doji manipulated Ryuga by provoking him as all bladers had to work together to lock Nemesis away with Zeus' Barrier. He even calls him a pawn in hades Grand plan and by saying how pathetic he is to be frends with Gingka. this resulted in Ryuga attacking Nemesis alone and the dark bey being revived, Doji, Pluto, and Rago, the blader who wielded Nemesis, fled the temple they were in and went to the lost city of King Hades as this was the place where they wanted to build their new kingdom after releasing Nemesis' full power to destroy the world. However, Ryuga had followed them to fight Nemesis alone once more, seeking the bey's power for himself. During the battle, Doji taunted Ryuga about being weaker than Nemesis until Ryuga, enraged by this, released a new Special Move to attack Nemesis. Despite it couldn't destroy Nemesis, the impact from forbidden beys clashing was enough to send Doji falling down into the abyss, who was laughing maniacally, claiming it to be the best feeling in the world.

Beyblade: Shogun Steel

While he is physically dead, it is revealed that Merci has preserved his body long enough to be able to create a digital version of his personality. United with Merci's system, Doji has secretly been pulling the threads of the DNA organization as a revival of Dark Nebula - even the name stands for 'Dark Nebula Again'. He even uses Kira Hayama to be the strongest and take over the beyblade world with the help of Argo Garcia and his siblings.

During the WBBA team challenge matches, Kira Yoshio Iwayama Captain Arrow and the DNA members invade the stadium and interrupts the challenge. He then appears in front of Zyro, Shinobu and Ren as a hologram, and tells them how he survived and reveals that he is the true leader of DNA. He captures Gingka through Baihu Xiao having him give the Pegasus warrior wheel to Kira creating Pegasus Bahamoote, and gathers all the protagonists at the DNA headquarters for a final battle against the organization.

However, the DNA bladers are all defeated by Zyro and his friends including Sakyo Kurayami and Takanosuke Shishiya. During Kira and Zyro's battle, Doji enters a robot body he had prepared. It then sends Phantom Fenrir to defeat Salamander Ifrit, but Fenrir is easily defeated by Pegasus Bahamoote. It first appears more like a giant beetle, but then transforms into a mega-sized beyblade. After this bey-version of Doji is defeated by Gingka, Zyro and a redeemed Kira it starts malfunctioning. Determined to not let them win over him, Doji throws himself down a hole in the building, causing an explosion that destroys the entire headquarters. Before this, he states that Gingka and the others would not be there to see the 'future of beyblading' which they speak about. His plan ultimately failed when everyone, including the DNA Bladers, escaped from the building and Doji was lost for good.

Doji and Ryuga worked hand in hand since they had raided Koma Village, stolen the Forbidden Bey and defeated Ryo Hagane. They both followed a plan to unleash L-Drago's true power upon the world, which ultimately backfired in the end. Doji set up Battle Bladers in order to get plenty of strong bladers together for the purpose of feeding power to L-Drago. Doji's efforts greatly powered up the Forbidden Bey since they had stolen it. However, he didn't believe L-Drago was strong enough to defeat Gingka Hagane, even after sending the defeated Dark Nebula members to their misery. This decision causes him to capture Yu, defeat both Kenta and Hyoma and battle Phoenix, only to end in defeat. Ryuga confronts his crazed self, only to find that Doji had been going to extreme lengths to obtain more food for him. Believing that Doji was doing this only because he thought L-Drago was too weak, Ryuga breaks Dark Wolf in half, taking Doji's soul in the process.

Doji's return in Metal Fury only made their relationship worse. As revenge for the damage L-Drago had done, Doji degrades Ryuga for helping Gingka out. He plays with the L-Drago user's emotions as if he knows exactly what's going on in his head. By doing this, he was able to make Ryuga leave Zeus's Barrier, causing Nemesis to awaken. However, Doji wasn't done toying with Ryuga yet, as he continues to taunt him for being used for the plan. This angers Ryuga greatly, turning his initial disgust for Doji into pure hatred. And then died soon after Ryuga's and Rago's battle as the force from L-Drago pushed him off the edge of a cliff.

They both seem to see each other as a past they need to put an end to - in Metal Masters, Ryuga faces the HD Academy in order to free himself from his Dark Nebula past and in Shogun Steel, Doji seems to specifically aim for a mental 'win' over Ryuga, in order to get revenge for the health damage done to him and betrayal.

Gingka Hagane

Doji was Gingka's greatest foe ever since the two first met in Koma Village. Gingka had a will to defeat the Dark Nebula and Doji after they presumingly killed Ryo and stole L-Drago. Gingka would later meet Doji again after beating Kyoya for the second time he vowed to make Doji pay for all he did. Since then the two have been sworn enemies. When Doji returned in Shogun Steel Gingka swore that Zyro would stop him.

Ryo Hagane (Phoenix)

Like Gingka, Doji was always at odds against Ryo, especially after Doji and Ryuga stormed Koma Village to steal L-Drago. Ryo attempted to stop them, but failed and Doji and Ryuga tried to leave him for dead, which was in vain when Hokuto rescued him. At some point, Doji came across a mysterious blader named Phoenix with the beyblade Burn Fireblaze 135MS, who did whatever he could to stop Dark Nebula's reign over Beyblading. He knew that Ryo was actually Phoenix the whole time, given that they had similar ideals. After Doji loses their battle during the Battle Bladers semi-finals, he laments on how he didn't finish off Phoenix (Ryo) during his Koma Village invasion.

Dr. Ziggurat

Dr. Ziggurat didn't reveal himself to be the mastermind behind Doji and Dark Nebula until he brought Ryuga to HD Academy. Dr. Ziggurat and Doji most likely had a boss/employee relationship, although conversations between them were never seen in the anime. He was responsible for sending Doji to find the Forbidden Bey, bring Ryuga to it, bring him up to his fullest potential and ultimately unleash the power of L-Drago upon the world. The plan backfired, and since then, it is unknown if Dr. Ziggurat and Doji have talked.


Now Doji's new boss, Pluto sent him to search for the Child of Nemesis. Near a waterfall, Doji discovers a prison-like cave, where the rightful owner of Diablo Nemesis X:D, Rago and his Nemesis Bladers are found. Certain that he is the one, he takes all four of them with him to the Temple of Pluto. As seen in episode 135 , Doji appears to have great respect for Pluto, bowing down to him. The two are working together to serve Rago, bring the return of Nemesis and destroy the world all together.

Yu Tendo

In the beginning, Yu's and Doji's relationship seemed fairly relaxed. It's been shown that Doji even went out of his way to design a huge playing room with a great amount of toys for Yu. He's been fairly lenient for Yu's requests as well and usually let him casually spend time at his office. Doji even attempted to tell Yu about his feelings (concerning cacti, specifically), but it ended up a one-sided monologue, seeing Yu was never interested.

Their fairly good relation immediately changed by the time Yu started being influenced as Gingka and seeing Beyblading as fun. Any friendliness Doji ever showed him vanished completely, being replaced by the strict cruelty he also displays to other members of the Dark Nebula. It seems as if he saw Yu's change of heart as such as treason. He also had no problim kidnapping Yu to use his power for Ryuga.


He first met Kyoya after he lost to Gingka.At first Kyoya did not trust Doji. But after losing to him in the mountains he knew he had to train with Dark nebula. After getting new powers in Wolf cannon he fought Gingka again but he lost. Soon after that Doji clamed Kyoya didn't get much training and injured him and Leone. Once he realized the plan was for Doji to use him as a pawn, Kyoya joined Gingka in defeating the Dark Nebula. Doji then saw Kyoya as another eneimey to be stopped.


Beyblade: Metal Fusion

Beyblade: Metal Fury


    • Doji enjoys drinking orange juice stored in fancy and luxurious wine bottles and wine glasses to "replenish his body with vitamins" and also likes eating dry-cured ham and goat cheese claiming that it is "Mankind's greatest invention."
    • He also has an apparent hatred for cacti, though he secretly loved them.
    • He and Ryuga are the only characters from Metal Fusion who didn't show up in the final picture of Blader's Spirit.
    • Whenever Doji appears, most of the time only one side of his eyeglasses is seen which is right and in some episodes, it is seen on the left side.
    • When he removes his eyeglasses during battle, he has a dark aura and his opponent gets captured in a dark bottomless hole as seen with his battle with Phoenix.
    • In Metal Fury, he reappears with a scar on the left side of his face. The scar might possibly stem from Lightning L-Drago's attack on him in Metal Fusion. This is further supported as the according eye blacks out the moment he falls in that episode. In Metal Fury, the eye is passed by the scar and he only wears a monocle over his other eye. This indicates the scarred eye is blind or made of glass, seeing it's no longer in need of eyeglasses.
    • In Metal Fury, Doji did not obtain and or use a new Bey.
    • Doji has been nearly killed by Ryuga twice. The first being in Metal Fusion when Ryuga sucked out all of Doji's life force. The second being in Metal Fury when he causes Doji to be thrown off a cliff.
    • In Metal Fury, his hair is grey, most likely due to Lightning L-Drago stealing his life force.
    • Doji manipulating experienced bladers into his plans makes him similar to Boris Balkov from the original series.
      • Both antagonists were also revealed to have served under another antagonist before becoming independent themselves after that antagonist disappeared.
      • Both Doji and Boris shares the same Japanese voice actor: Takehito Koyasu.
    • He resembles Masamune Kadoya and because of that, many thought Masamune was his son. It turns out they are not related at all. The only connection they share is that Masamune wears clothes of the brand 'Daido-G' which is a sub company of the Dark Nebula organization. This has been confirmed by Takafumi Adachi on his blog and might only be true for the manga canon.
    • It is also known to be that when Doji asked to change his bey parts to defeat Gingka, he first changed the fusion wheel to Dark fusion wheel as he did it for Benkei and Tetsuya.
      • The first form of his mecha in Shogun Steel resembles the E-12 Behemoth from Sonic X and Ceph Pinger from Crysis 2.
    • Doji is one of the only 2 veteran characters who battled in Shogun Steel, the other being Gingka Hagane.
    • Doji's recent Beyblade, Phantom Fenrir T125JB was never released.
    • The second form of his mecha in Shogun Steel during the battle against Gingka, Zyro and Kira resemble Giant Bowser battle in the final level of New Super Mario Bros U. This level name is the final battle.
    • He bears a striking resemblance to Dennis Isenberg from Lost Planet
  • He has a habit of discarding people he finds have served their purpose as shown with Kyoya, Ryuga, Yu, Tobio and Ryuto.
  • After 31 episodes Doji’s English voice Juan Chioran was replaced by Andrew Jackson. This was most in part due to fans complaining Chioran’s voice was “lacking emotion” and “didn’t fit the character well”. Since then he has been voiced by Jackson whom many fans highly praised for being more “sinister, young, and true to the character”.
