Beyblade Wiki
You're wrong; it's not so I can defeat you, it's so I can destroy your entire being.


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

Reiji Mizuchi (水地 零士, Mizuchi Reiji) is one of the primary antagonists in Beyblade: Metal Fusion. He is a member of the Dark Nebula, being their true second most powerful Blader after Ryuga.

Initially, he was assigned by Doji to watch over Gingka Hagane to study his Storm Pegasus 105RF. He later takes part in the Battle Bladers tournament; he follows a strategy of attacking opponents weakly to lower their guard and injecting "poison", when they become vulnerable to the ultimate assault of his Poison Serpent SW145SD.


Reiji is a noticeably pale, skinny boy with red hair with a blonde streak running through the front of fringe. His eyes are bright yellow, but they seldom show as his fringe covers them. His eyes are also noticeably serpentine when dilated.

He wears a long blue shirt with a snake-scale pattern across the bottom of his shirt along with a scale pattern on the cuffs on the arms. His shirt is tied with a double-crossed dark brown belt. His jeans are black. A notable feature of his appearance is his snake eye styled hair clips. He often walks sloppily, wavering and never actually walking or standing up straight. When talking, he has a habit of pointing with his fingers, and making exaggerated motions.


Reiji is a boy whose personality changes drastically when he enters battle. When outside of Bey battles, he is rarely (if ever) seen talking and seems to be content with observing events that are happening around him. This same behavior is often displayed even when a battle has started - it is only when a battle gets more heated that he begins to speak and show his true colors.

Reiji's battling style is reflecting his sadistic personality; he prefers to either playing with his opponents cruelly to ending the battles as fast as he can. If there is one thing Reiji enjoys, it is the fear of others. Therefore, he can't understand a battling style based on enjoyment and friendship; in fact, Gingka having fun during his battle with him is actually highly unsettling to Reiji. It even appears that the concept of the Blader's Spirit causes him physical pain, but in the form of headaches.


Beyblade: Metal Fusion

Reiji first appears at the Battle Bladers tournament after Gingka beats Yu in the first round of the tournament. Doji tells him that it is time to show Gingka's gang how cruel they can be. After Kyoya Tategami beats Kumasuke Kumade and Tsubasa Otori beats Reiki Sodo, he is assigned to battle Hyoma during the first round where Gingka, Benkei Hanawa Kenta and Kyoya learn nothing about him. During his introduction, Blader DJ mentions that there is no information on Reiji as a person or on his Beyblade and not having any data competing in the challenge matches. even Tsubasa knew nothing about him despite the fact that Tsubasa was a dark Nebula spy.

His battle against Hyoma first appears to be rather one-sided, with Hyoma outmatching him. However, when things appear decided, Reiji finally begins attacking fiercely. While Reiji could end the battle with ease if he wanted, he instead proceeds to slowly torture Hyoma's Rock Aries ED145B and shatter the bey into tiny pieces in the process. After Hyoma tearfully begs him to stop, Reiji finally ends the prolonged fight and wins using the Venom Strike. He then walks off stage sadistically thanking Hyoma for the battle while Hyoma drowns in tears.

Reiji next appears, when he fights Yu Tendo as punishment for Yu's loss against Gingka at Battle Bladers during the first round. Yu is told that he'll be set free if he is able to beat Reiji. In their battle, Reiji uses the same strategy he used against Hyoma, which he calls the 'Serpent's Poison'. While he appears to be victorious, Yu suddenly orders Libra to use Inferno Blast and takes his chance to escape during the resulting confusion. When the second round begans Rejji is shown to be amused at the changes and gives Kenta a glare. Later after Ryutaro Fukami loses to Gignka in the second round, Doji tells Reiji that he will be taking care of Ryutaro. But the actual battle is never shown (it should have happened between episodes 43 and 44).

Back in Battle Bladers, Reiji has to face Kenta Yumiya. When the battle begins, Kenta tells Rejji that beyblade is something to be enjoyed causing Rejji to be confused. He starts out by following his usual strategy, but then begins to break off Flame Sagittario C145S's claws one by one. However, Sagittario is not defeated this easily; Kenta, who has combined his Beyblade with Flame Libra's Eternal Sharp Performance Tip for this battle, begins speaking of his friendship with Yu and the others, and his experiences with them are makes him this strong. At this point, Reiji finally gets angry for the first time, being unable to stand what Kenta is saying; his rage causes his real eyes to show between his hair. In this state of anger, Reiji begins damaging Sagittario more and wins by stopping Sagittario's rotation with his Dark Move. While this is his formal victory, Reiji declares that he is unsatisfied with his victory and continues to attack Kenta's bey in an effort to break him even more. In an attempt to protect his Beyblade, Kenta enters the arena himself; Reiji might have attacked (or even killed) the young boy, had it not been for Gingka Hagane's interference. Gingka demands that Rejji stop his path of districution. Reiji however delcares that the bladers sprit is useless and he will prove it by beating Gingka.

As a result of this sudden turn of events, Gingka is selected as Reiji's next opponent in the semifinals causing Gingka to tell Rejji that he will take Kenta's place and beat him. Once the semi finals begin, Reiji reveals that the Dark Nebula has watching Gingka's battles in a secret research area filled with numerous screens. He always wanted to defeat Gingka and erase his love of friendship, as a form of proof that even a powerful Blader can be helpless in fear. As their fight goes on, it appears as if Reiji is about to defeat Gingka, who has seemingly turned to stone due to negative emotion. However, Gingka manages to break free and declares that he is still having fun battling Reiji. Reiji can't understand why Gingka is not afraid of him, starting to lose his composure and attack Pegasus again. Gingka finally finds an effective strategy - he blocks Reiji's attacks by successfully mirroring his movements; Reiji finally starts to feel fear himself as he notices that Gingka, who is still smiling, is about to win. He is therefore defeated, and has a complete breakdown, unable to comprehend or believe his loss and was unable to scare the other Blader; he then imagines himself ironically turning to stone by his own negative emotions.

The last time he is seen is on the ending picture of the season, angrily walking away from the other celebrating characters. It is currently unknown what happened to him after the events of Metal Fusion as he isn't seen in Metal Masters or Metal Fury.

Beyblade: Metal Masters



Poison Serpent SW145SD: Reiji's primary Beyblade in Beyblade: Metal Fusion. It is a powerful Balance-Type with incredible attack and defense capabilities and precautions. Its Spin Track and Fusion Wheel optimize for its greatest endurance and balance. Being based on a snake, it has the ability to wear the opponent down with every hit, slowly but surely infecting the victim with poison. One feature that Reiji noted about his bey is that the Spin Track has two special sets of "fangs". If the blades are reversed, they are defense fangs that can withstand an opponent's attack; in its original forward motion they become attack fangs which wear down and destroy an opponent's Bey. As the monster Medusa from Greek legend, Poison Serpent can freeze the opposing bey in its tracks through using a spatial field, and it requires enormous willpower in order to break free from its gaze. 

Special Moves

  • Venom Strike: Serpent unleashes a large flurry of attacks to ultimately poison and defeat the opponent. Like Lightning L-Drago, it is referred to as a "Dark Move".

  • "You're wrong; it's not so I can defeat you, it's so I can destroy your entire being!"
  • "This can't be the end of this; entertain me more, pretty please. At this point, there's no fun in breaking you."
  • "You've started to fall apart nicely: more, struggle more, more! Become more frightened and don't give up! If you stop trying, you'll become nothing just like that worthless Bey."
  • "'What is Beyblade?' you ask? Do you tell me then, Hyoma. You're scared. You're just so scared that you don't know what to do next, do you? Too bad because you can't run from me anymore; that's a fact. I'll defeat you so completely that you'll never be able to pick up a Bey ever again."
  • "Now that was a fun battle."
  • "The losers become food for the Dragon."
  • "But before that, I need your help. You don't mind helping me with my warm-up, do you little buddy?"
  • "It looks like the poison has taken effect."
  • "Even now, Poison Serpent's poison is working its way through Libra: if you do nothing, if you don't try to attack, you will definitely end-up with a sleep-out."
  • "Even a tiny fragment lost is a fatal wound for a Bey; this loss causes the Bey to lose its balance and its power is gradually drained away. It's as if a snake's poison was circulating through it's entire body!"
  • "The reality is, without using my full strength, your power has been completely drained. That's the taste of sssadnesss...seeing your precious Bey cut-up right before your eyes can't be fun?"
  • "Well, shall I pull an end to this now?"
  • "I heard the same thing from that kid, Yu, but, as an answer I pounded fear into the little guy's very core."
  • "Interesting. If you wouldn't have used that silly trick it would have been over with that last hit...but now, your suffering will have to continue."
  • "Not enough. I will crush all of its parts."
  • "That's good, don't give up just yet. That way I'll get more pleasure from breaking you."
  • "Look at your broken Bey. What can you do with a Bey like that? You can't complete your goal and you can't fulfill your promise to your friends. Right now, you are the same as that useless bey."
  • "W-What are you doing to my beautiful bey?"
  • "Stop it! Stop it! if you do that, if you do that...that really hurts!"
  • "I won't forgive, I will never forgive you."
  • "Destroy everything, break it, break it, smash it apart!"
  • "I'll tear your spirit apart, do you hear me? So you won't be able to touch a Bey ever again."
  • "A Beybattle is for crushing your opponent until there is nothing left; not even the Blader's spirit."
  • "'I'm wrong?' Nonsense. Everything you're saying is complete nonsense."
  • "I I can't remember when it was, but the first time I saw you, you were shining so bright. It really was brilliant you know. I was blinded by your talent, but more than anything I wanted to take you down, Gingka. I wonder, what will your face look like when I take you down? Will it smirk then, as Pegasus breaks to pieces? Now go ahead and take your shot at me; I am going to crush everything that you've got."
  • "How is it? Is it painful? Even so, I won't allow you to be defeated with just this. I want to see you struggle much harder to survive."
  • "That's good. Keep it coming! The thought of that proud face of yours filling with fear gives me goose bumps...I'm really, really looking forward to it, Gingka!"
  • "All I want to see is your face as you whimper and cry. I want to see your spirit crumble, and when I think about it, I just can't wait anymore."
  • "Yes, turn to stone, turn to stone and then break apart, along with your precious Pegasus."
  • "Now, let me hear it, Gingka; the wonderful sound of your scream."
  • "I want to enjoy the fact that I'm the one who scares you the most."
  • "Why?! Why are you smiling?! ... "Tell me!"
  • "My fun comes from filling you guys with fear and despair."
  • "Break it, smash apart, see what true fear feels like when it shakes you to your core."
  • "Don't smile! Don't look at me all happy!"
  • "It can't be! The one who's scared is me?!"
