Daidouji

For the Back to the Basics Blader Style profile for Doji, see Doji (Back to the Basics).

Daidoji(or Doji in the English dub) was an executive of the Dark Nebula. 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.

Appearance
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.

Personality
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 100 HF when ever they fail at the task they are given. 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. He also had no problem betraying his allies when they are no longer of use to him as shown when he brutally injured Kyoya after his loss to Gingka fed the power of Dan, Rekei, the Kumade bros, Yu and Testuya to Ryuga, Showing no concern over the Dark nebula bladers that Hyoma beat, mocking Ryuga during his fight with Rago and making sure Kira falls to his death following his loss to Zyro.

Beyblade Metal Fusion
Not much is known about Daidojui's past. The only scene involving Doji was the event in which Ryuga obtained the "Forbidden Bey", Lightning L-Drago. 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, Ryusei Hagane. Ryuga beats Ryo using L-drago and gets away. Gingka yells at them to come back causing Doji to mock same saying he should be glad L-Drago did not steal his power. It was most likely his decision to place Ryuga in a coma until Lightning L-Drago 100 HF 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.

After Gingka Hagane left Koma Village on his quest, Doji kept a low profile as he waited for L-Drago's power to awaken. He kept watch on Gingka and his various battles. After hearing that Gingka beat Kyoya Tategami in Metal Tower. He arrived at his hideout telling him that he will help grant Kyoya's wish to beat Gingka, dragged him and his friends to a foggy area and began making small negotiations with him and his gang the Face Hunters. Kyoya asks how Doji even knows Gingka only for him to tell Kyoya that if he joins him then he shall know why. He tells Kyoya that if he trains with the Dark Nebula he can become even stronger than Gingka and remarks that as he is now Kyoya will be killed. 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 Lion 100 Fang Fury to get some good hits on Wolf. However Kyoya's Lion Gale Force Wall proves to be ineffective against Wolf with Doji commenting that his move is like a lion trapped in a cage. Rock Leone then begins to use its Special Move to eliminate Wolf with sheer force, but Doji appears to know Kyoya's weakness.

Wolf breaks through Lion Gale Force Wall and nails a critical hit on Leone, but not only that, Doji is revealed to have a special move - Darkness Howling Blazer! 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 than has Kyoya board the helocipter with him leaving the Face Hunters without there leader. Doji later meets up with Kyoya's best friend Benkei Hanawa at the Face Hunters hide out. When Benkei demands to know what happened to Kyoya, Doji tells him that Kyoya is training to increase his power. He then gives Benkei Dark Bull H145 SD, 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 where Kyoya disbands the Face Hunters, injures Benkei and Kenta in battle and challenges Gingka to a battle. During there battle Doji is shown eating pizza using a fork and knife saying that eating like that is more civilized. His servant arrives to give Doji a video of Gingka and Kyoya's fight. The battle goes both ways and it looks like Gingka may lose which pleases Doji. However in the end Gingka wins by using Meteor Shower Attack.

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 (Daidouji) 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, Kenta, Benkei and Madoka cannot enter the castle. Gingka, Kenta and Benkei struggle to beat the various beys thrown at them while Doji looks pleased saying that all the hospitalty they had for them will be in vain. 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 and ridding on King Lion Tearing Blast. Doji and Merci have prepared traps to stop them such as a huge beyblade, a fast moving treadmill, training bladers and many more. but they still succeed in passing by all of Doji's tasks and challenges including taking down Dan and Reiki Sodo. Gingka reaches Doji where he applauds Gingka's effort in finding him. They start talking about the undefeated Lightning L-Drago 100HF and how Gingka is determined to face it again. However, Doji plays a trick on Gingka and tries to get him to realize that if he joined Dark Nebula, he would get a lot more power in the end thus trying to manipulate him much like how Doji convinced Kyoya to join him. Gingka, recalling the death of his father at the hands of Ryuga and Dark Nebula, strictly refuses Doji's 'offer' and challenges him to a battle as revenge for his father. A battle sparks between the two, causing Ryuga to awaken from his coma. Doji proves to be a strong opponent even beating Starblast Attack. Doji loses due to Gingka's spirit rising, but this fails to faze him. Gingka and Doji run outside to encounter Ryuga's return. Gingka challenges the Re-Awakened Ryuga to a battle foolishly and Ryuga accepts. he tells Kyoya Benkei, Kenta and Madoka how bey's are known to have a hidden power within them much to their shock. He oversees Ryuga and Gingka's battle, knowing that Storm Pegasus 105 RF is really feeding power to L-Drago. Gingka's friends have trouble understanding what makes Ryuga's Beyblade so strong, so Doji explains that it is due to the fact that L-Drago is a left-spin blade. Gingka gets really angry and causes Ryuga's power to increase. Gingka loses, and Doji reveals that it was Gingka himself that helped L-Drago awaken, causing the boy to fall in shame. Ryuga then told Doji to get the plans ready for battle Bladers.

Ryuga's awakening causes Doji to appear less often, usually spending time in his office overseeing Ryuga's battles with Dark Nebula Bladers. He watched Ryuga battle his squad that used all types of Beyblades. After Ryuga uses L-Drago's power to beat them all and trash the area, Doji looked pleased at Ryuga's power. Doji then asked Ryuga how strong he wished to be causing Ryuga to smirk. 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 much to the horror of Gingka's friend's. 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. Ryuga and Gingka battle again with No outcome. 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.

He later had several agents sent to diffrent cities to search for strong bladers. One of them, Kumasuke Kumade, was defeated by Tsubasa, who later joined the Dark Nebula after an intense battle with Yu.

In episode 27, he sent Yu and Tsubasa to sabotage a tournament to delay Hyoma and Kenta from getting into Battle Bladers.

He sent Yu, Tsubasa, Myreille, Dan, and Reiki to another tournament, which they ended up losing.

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. Tsubassa defeats all of the Dark Nebula's lower class bladers such as the Kumasuke Kumade, Kumaji Kumade, Kumata Kumade, Dan, Reki Tetsuya Watarigani and the Dark Nebula Bladers. but Ryuga shows up just in time to battle him. When Doji and Yu challenge Tsubassa to battle Ryuga tells both of them to stand down. Doji believes that Ryuga will win after Earth Eagle 145WD gets it's power absorbed by L-Drago. 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. 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 Gingka 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. Ryutaro becomes angry at Doji's cruel behavior casuing Doji to tell him failure must be dealt with. 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.

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. Kenta demands Doji realize Yu only for Doji to tell him that Yu must give his power to Ryuga. He tells Kenta that Yu was merely a pawn to help Ryuga become king. They battle for only a short while, as Kenta was using a stolen light wheel bey known as Clay Hydra 145F. 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 C145 S 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. Burn Fireblaze 135 MS proves to be a tough bey for his Wolf to handle. 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. Later, Doji breaks free from the crystals. He becomes crazed for Ryo'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 by Pegasus and its new move Galaxy Nova, Doji's soul, like everyone else's souls, was placed back to his body. He then went into hiding.



Season 3: 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 known as Prototype Nemesis, Doji manipulated Ryuga by provoking him as all Legendary 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 now being known as Diablo Nemesis X:D, 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.

Season 4: 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, Spike Bourne, Genjūro Kamegaki, Baihu and many DNA bladers invade the stadium and interrupts the challenge. He then appears in front of Zyro Kurogane, Shinobu Hiryuin and Ren Kurenai as a hologram, and tells them how he survived during Ryuga and Rago's battle and reveals that he is the true leader of DNA. He even lies saying that Gingka joined him. He captures Gingka through Baihu Xiao having him give the Pegasus warrior wheel to Kira creating Pegasus Bahamoote SP230R2F, and gathers all the protagonists at the DNA headquarters for a final battle against the organization. he uses Karura to guard the fortress until he is beaten by Kite Unabara.

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 known as Robo Doji. It then sends Phantom Fenrir T125JB to defeat Salamander Ifrit W145CF, but Fenrir is easily defeated by Pegasus Bahamoote. After Kira loses to Zero once again the staduim begins to fall down. Doji taunts the two saying that Kira's pride was now going to be his downfall. Kira gets angry and learns that Doji just used him After Zero and Kira are saved by Yoshio, Doji enters another suit to do battle. It first appears more like a giant beetle, but then transforms into a mega-sized beyblade. Zero and Gingka try to fight it but are no match, but Kira arrives to help with Behemoth Golem DF145BS. Kira announces his decision to leave DNA and side with Zyro and Co. who is dissatisfied with what Doji has done to DNA and ends his affiliation with it. The three Bladers let out their true potential in the real final battle. Zyro activates "Super Burning Upper" while Gingka uses 'Galaxy Nova' and Kira creates "Rising Gaia Hammer". The three Special Moves combine to create one of the most powerful moves in Beyblade history. The moves swirl together and land on Doji's mecha Beyblade, causing it to cease spin, completely. 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.

Ryuga
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 and thus ending their friendship.

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.

Pluto
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 problem kidnapping Yu to use his power for Ryuga.

Kyoya
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 Canyon 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 enemy to be stopped.

Trivia

 * Daidoji has a comical obsession with cacti. He keeps them in his office to admire. In Episode 28, he lectured Yu Tendo about how much he despises them, despite literally surrounding himself in their presence.
 * It is ironic because until episode 42, only he and Ryuga were in on the plan to feed weak bladers to L Drago. Little did he know he would become food himself.
 * He, the Dark Nebula Bladers and Ryuga are the only characters from Metal Fusion who didn't show up in the final shot of Blader's Spirit.
 * So far he only used his true power once during his battle with Phoenix where the opponent goes into a dark bottomless hole.
 * He seems to favor the Dark fusion wheel because his first beyblade had the dark fusion wheel and he gave Benkei and Tetsuya bey's with the dark Fusion wheel.
 * Doji and Masamune Kadoya share a very simlair streak hairstyle.
 * 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 Beyblade Metal Fury, Doji did not obtain and or use a new Bey.
 * It is very common for Doji to betray others when they no longer serve any value to him. So far Rago, Pluto and the Nemesis Bladers are the only blader's he never betrayed.
 * 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, Bao, Keyser, Cycnus, and Herschel are the only villains in Beyblade Metal Fury who do not appear in the theme song.
 * He never won any battles in Beyblade Shogun Steel.
 * 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.
 * In Metal Fury, Doji did not obtain and or use a new Bey.
 * It is very common for Doji to betray others when they no longer serve any value to him. So far Rago, Pluto and the Nemesis Bladers are the only blader's he never betrayed.
