"You're wrong; it's not so I can defeat you, it's so I can destroy your entire being."
"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! You should stop trying and become nothing just like that worthless bey."
"What is Beyblade you ask? Do tell me then, Hyoma. You're scared. You're just so scared that you don't know what to do next, are 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 again."
"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."
"Could be ; even now , Poison Serpent's poison is working it's way through Libra ; if you do nothing , if you don't try to attack ; you will definitely end-up with a sleep-out"
"I told you already didn't I : Libra has already been affected by Serpent's poison understand"
""Why" you say; don't you understand what those are down there : they're fragments of Libra's parts , that Serpent has broken off"
"Even a tiny fragment is a fatal wound for a bey, it's lost causes the bey to lose it's balance and it's 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 ssadnesss, seeing your precious bey cut-up right before your eyes can't be fun; this is true sorrow; next for you; this is fear; I'll give you a good taste of my Dark Move that is: Serpent Venom Strike"
"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 fairly core ; I'll show the same fate to you soon enough with this Poison Serpent"
"Hun , not bad , but Serpent's poison should be steadily working it's way through your bey as we speak ; let's see if you can keep up with this movement"
"Try this"
"No way , how is he able to follow"
"What's going on ; Serpent's barrage attacks seem to have done it's job well enough ; so why isn't the poison circulating"
"Don't get to exited ; if this is your plan, then I'll inject all my poison at oncce ; show your fangs Sserpent"
"One claw gone ,two claws, hey there little buddy if you don't hurry and run away that last claw will be gone too ; three claws ; now it's over"
"Interesting ; if you aren't to use that silly trick it would be over with that last hit ; but now your suffering will have to continue"
"Not enough ; I will crush all of it's parts"
"You're not fighting alone you say you, you won't back down, not now not ever, interesting, I wander can you keep saying such things as you watch your bey turn to dust before your eyes"
"That's good ; don't give up just yet ; that way I'll get more pleasure from breaking you"
"Well, how does it feel to not be able to do anything as your precious bey is destroyed^Feeling a bit cold ; like maybe your fear was turning to stone ; tell me how it feels to have your bey's fusion wheel, spin track and performance tip broken apart when you can't do anything ; look at your broken bey ; what can you do with a bey like that ; you can't complete you goal and you can't fulfill your promise to your friends ; right now ; you are the same as that useless bey"
"He acts like nothing happened"
"What can you do with a broken bey like that"
"Impossible , how could there be that much power left in that broken bey"
"It's spirit"
"What are you doing to my beautiful bey"
"Stop it stop it ; if you do that, if you do that ; that is really hurt"
"I don't wanted to hurt"
"I won't forgive, I will never forgive you"
"Destroy everything, break it, break it, smash it apart"
"Crush it, crush it ; into nothing 10"
"The bey-path that you have followed : confidence, friendship ; I'll crush all of it ; right here, and now"
"It's not over yet ; he's bey still hasn't been crush to nothing ; it still hasn't been broken enough for my liking"
"I'll tear your spirit apart, do you hear me ; so you won't be able to touch a bey ever again"
"So , it's you : Ginga"
"A Beybattle is for crushing your opponent until there is nothing left ; not even the Blader's spirit"
""I'm wrong?" Nonsenss ; everything you're saying is complete nonsense"
"And it your turn next ; do you hear me Gingka ; I will completely destroy your bey and your spirit ; just like I did to the others"
"I have to say ; I'm so very very happy Gingka ; I finally get a battle with you ; I've been looking forward to it so much ; the time when I can break you and Pegasus and all fun this will be ; 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 ;; more than anything I wanted to take you down Gingka ; I wander, 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"
"Hey there ; enjoy the sting of Serpent's real fangs"
"You see my Poison Serpent has two faces, two separates identities : up until now Serpent's spin track has been reversed, making it to defensive spin track that can deflect the opponent's attacks but when it flips over it turn into attack fangs that can rip apart anything"
"Now you'll see Poison Serpent's true power"
"What the matter ; is that all the power Pegasus has to offer"
"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"
"Hun, no matter where you run, I will follow you ; Chase it Chase it Chase it into a corner"
"All I want to see is your face as you whimper and cry, I wan to see your spirit crumble ; when I think about it I JUST CAN'T WAIT ANYMORE"
"Has your spirit become to grow cold with fear"
"More and more you'll get colder and colder ; you hear me ; and then you and Pegasus are going to turn to stone understand"
"Yes, turn to stone, turn to stone and then break apart ; along with your precious Pegasus"
"How does it fell ; frozen there ; just waiting for the moment when you will be smashed apart ; pretty scary hun"
"It must be so appall being that scared of me that you can't hold back ; and just want to scream and cry like a little baby"
"Now, let me hear it Gingka ; the wonderful sound of your scream"
"I get it ; you're so scared that you can't move your body at all ; but that no fun ; I want to see your face contorted ; you know, in fear, and a little sobbing would be welcome too ;; now I'm begging you, please turn your wimpy w$d§%l£ face toward me ; that sad face that shows me your scare ;; ?!because I want to enjoy the fact that I'm the one who scares you the most"
"Hey, why are you smiling"
"Tell me"
"Funny (this line is better in French(!the line not the actor-voice!)"
"The final, that's it ; even now I give you all that deadly poison ; tell me why ; why don't you fear me"
"How can you get excited"
"You're still smiling*"
"My fun comes from feeling you guys with fear and despair"
"Break it, smash apart, see what true fear feels like when it shakes to your core"
"Don't smile don't look at me all happy"
Trivia
'Reiji' is a common name given to people in Japan and 'Mizuchi' was a Dragon that looked like a snake.
But it doesn't explain how the beast changed in the middle of his battles with Gingka. However, this is the show, and has had other instances of 'mode changes' only possible between battles, such as height changes or tip changes on Dark Gasher CH120FS and Storm Aquario 100HF/S, respectively.
He is the only character from Metal Fusion who did not make an appearance in Metal Masters.
His Beyblade, Poison Serpent SW145SD, is the first to have a beast change.
The 'serpent' in 'Poision Serpent SW145SD' is a garden snake, but is shown as a cobra, and only everal garden snakes as Medusa.
