Now it was on to the Fourth Stage! 

And up ahead was- 

Mokuba: Well, you finally made it. 

(Y/N): Mokuba! 

Joey: Who's the kid? 

Ruby: Kaiba's little brother. 

Weiss: That little brat, poisoned Ruby! 

Joey: HE WHAT?! 

Ruby: Wait, Joey! He's a victim too! I know it! Let me talk to him! 

Weiss: No, what if he tries something and- 

Yugi: I'll go. 

Tristan: Yugi, what if it's a- 

Yugi: I have to do this. I'm tired of just sitting back and doing nothing. And I won't be afraid of my other self either. 

Tea: Yugi. 

(Y/N): Go for it. 

And then right before everyone's eyes, he transformed into Yami Yugi! 

Yami Yugi: (Y/N), Ruby, Weiss, Blake, Yang, Joey, Tristan, Tea, thank you my dear friends. 

Joey: Did he just- 

(Y/N): That's him. The other Yugi. 

Yami Yugi walked into the Battle Box. 

Mokuba: Let's do this! It's time to play my favorite game, Capsule Monster Chess! First, we'll get our capsules from this machine! 

Mokuba activated a Gatcha Machine, unleashing some capsules. 

Mokuba: Little does Yugi know, I've rigged the machine to give me all the strongest monsters! 

Mokuba's Monsters: 

Yugi's Monsters:

The rules are the game are simple! The last player with their monsters left on the board is the winner. Each monster has a level of 1-5 with different movement ranges and attacks. 

They place their monsters on the field, and they are shown below them. 

(Y/N): A hologram! Just like what Kaiba did with the Duel Monsters! 

Mokuba: First move goes to me, Yugi! Let's go! 

Armorsaurus goes first as Yugi sat there. 

Yami Yugi: I'll just sit right here. My formation is fine. 

Mokuba: He's planning something! No matter! I can do this! 

All of Mokuba's monsters soon surrounded Yugi's monsters! 

Yugi proceeded with his first move! 

And soon Armorsaurus destroyed Brain Slame with a flame breath! And it flattened Toppo by rolling around like Sonic or Felicia! 

Mokuba: HAHAHAHAHA! YOU ONLY HAVE THREE MONSTERS LEFT! 

And now it was going for Mogley! 

Mokuba: GO FOR IT ARMORSAURUS! 

But Mogley tunneled underground. 

Mokuba: WHAT?! OH NO! 

And then it flattened Megaton and died in the process too! 

Mokuba: MY MONSTERS! WAIT! 

He realized it. 

Mokuba: YUGI PLANNED THIS ALL ALONG! 

Yami Yugi: Mokuba, you rely solely on power, and that's why you've lost. You've neglected that even the weaker level monsters have special abilities that can be used for their advantage! 

(Y/N): YES! 

Joey: WAY TO GO YUGI! 

Yami Yugi: Now I move my Squid Ninja to attack your Zoid M. 

It self-destructed destroying Zoid M! 

Yami Yugi: And now the Evolution Spot is defenseless. 

Mokuba: NO! He's going to evolve his Beeton! 

Yugi moved Beeton to the evolution spot, causing it to evolve into Hyper Beeton! 

Yami Yugi: Even a weak monster will become much stronger if it get that far! 

And then Hyper Beeton destroyed Nama Hargen! 

Mokuba: NO! COME ON! BIGFOOT IS THE ONLY ONE LEFT! 

The two monsters charged at each other, and Hyper Beeton fell. 

Mokuba: HAHAHAHA! JYPER BEATON YOU'RE FINISHED YUGI! NOW FOR YOUR LAST MONSTER I WI- 

But Bigfoot fell apart! 

Mokuba: AAAAAAAAAGH! 

Yami Yugi: Looks like you didn't realize that it was a critical hit. I win, Mokuba. 

Mokuba: NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO! 

Yami Yugi then got up. 

Mokuba: YUGI! WAIT! How could you have won?! The power levels of my monsters were better than yours! I just don't get it! 

Kaiba then appeared on a screen. 

Kaiba: ENOUGH OF THESE SIDESHOWS! 

Mokuba: S-Seto. I- 

Kaiba: I've seen those pathetic clingy eyes like a dog's for years. It makes me sick. 

Mokuba: Bor, please don't! 

Kaiba: Did you forget that the loser gets a Penalty Game? 

Mokuba: NOOOOOOOOOOOO! 

The Monsters appeared before Mokuba! 

(Y/N): KAIBA! YOU- 

Ruby: AAAAAAAAAAAAAAAAAARGH! ENOUGH OF THIS! 

Ruby charged in and pulled Mokuba out! 

Mokuba: Wh-Why? After what I did to you. I- 

Ruby: Mokuba. I won't let you suffer because of your brother. I forgive you. 

He hugged her. 

Mokuba: I'm ... sorry. Ever since that day our father adopted us ... he became a demon. He used to be so nice. 

Ruby: Don't worry, Yugi will beat him. 

Soon... 

You all got ready to watch the fight. 

Yugi and Kaiba came face to face. 

Yami Yugi: KAIBA! I'LL NEVER FORGIVE YOU! 

Kaiba: Are you here to just spout needless words? Or are you ready to finish this? 

The two took their places. 

And their decks were taken out. 

(Y/N): It ends here. 

Yami Yugi: IT'S TIME TO DUEL!
