You, Selena, Allan, and Sayaka sneak around, searching for survivors when you see a familiar duel monster. Yuya's Dark Rebellion Xyz Dragon and another familiar creature, Kaito's Galaxy-Eyes Cipher Dragon

Sayaka: That's Kaito's Galaxy-Eyes!

Allan: And Yuto's Dark Rebellion Xyz Dragon!

Your Thoughts: Who's Yuto?

You run towards the Dragons and sure enough, Yuya and Kaito are dueling.

Shun: Kaito, that's enough. Yuya is here to help us.

Sayaka: Shun!

Kaito vanishes in light and you run over to Yuya, Gong, and Sylvio.

Y/N: Where's Yuzu?

Yuya: I thought she'd be here.

Gong: So after all that...

Sylvio: She's missing again...

Y/N: ........... FU-

All of you regroup at the hideout where Shun explains more of what happened when Duel Academy attacked. You and Selena look away in shame. Selena wasn't there but she wanted to be in the fight. You however, helped lead it

Y/N: I was fed lies. I was told we'd save the dimensions... But that doesn't change what I did...

Yuya: That's in the past. You've helped us a lot.

Sayaka: Plus, you did personally fight Edo Phoenix and won.

Gong: Who?

Allan: Edo Phoenix... He also lead Duel Academy's forces in the attack...

Y/N: He's dangerous... Hope you never meet him...

Sylvio: If he's anything like Kaito, I definitely would not be a fan.

Disembodied voice: Kaito Tenjo wasn't always like that... He used to duel for fun. Like you, Yuya.

You turn to see a translucent boy who looks a lot like Yuya only with purple and black hair.

Y/N: What is that?

Yuya: Hm?

Yuya looks at the boy and gives you a look like "I'll explain later"

Y/N: Nevermind.

You and Yuya head out and encounter two Duel Academy students.

Student 1: Surrender!

Y/N: In your dreams!

You and Yuya activate your duel disks and Cross Over activates.

Yuya: Ladies and Gentlemen, I'll take the first turn. I set the Pendulum Scale with Scale 3 Performapal Odd-Eyes Light Phoenix and Scale 8 Performapal Odd-Eyes Unicorn! This lets me Pendulum Summon monsters level 4 through 7. My monsters are ready to swing into action! Come on out Performapal Trump Girl and Turn up the heat, Odd-Eyes Pendulum Dragon!

Yuya's ace monster appears along with a small jester like girl.

Trump Girl Level 2 Atk: 200

Yuya: Next, I'll use Trump Girl's effect! She lets me Fusion Summon without Polymerization! I fuse her with Odd-Eyes Pendulum Dragon to Fusion Summon Rune-Eyes Pendulum Dragon!

The two monsters fuse into a dragon with a golden loop on its back and it lets out a roar.

(Rune-Eyes Pendulum Dragon Level 8 Atk: 3000)

Yuya: I set a card and end my turn.

Student 1: Draw! I activate Shaddoll Fusion! Since you control a monster from the Extra Deck, I can Fusion Summon using monsters from my main deck! I fuse Shaddoll Falco with my Earth Hex-Sealed Fusion! I Fusion Summon! El Shaddoll Shekhinaga!

A large mechanical creature with purple threads around its body appears.

(Shekhinaga Level 10 Def 3000)

Student 1: Since Falco went to the Graveyard due to a card effect, I can set him in face down defense mode. I set a card and end my turn.

Y/N: Draw. I activate Red-Eyes Insight! I discard Red-Eyes Wyvern to add Red-Eyes Fusion to my hand. I activate it. I fuse Red-Eyes Black Dragon with Summoned Skull! I Fusion Summon! Archfiend Black Skull Dragon!

Student 2: That monster... I remember this guy. He's one of the two traitors Commander Phoenix told us to look out for.

Y/N: Archfiend Black Skull Dragon! Attack Shekhinaga!

Your dragon annihilates the monster.

Student 1: Since Shekhinaga was destroyed, I add Shaddoll Fusion to my hand from the graveyard.

Y/N: My dragon's effect activates. I return Red-Eyes Black Dragon to my deck to inflict its attack to your Life Points!

Students' LP: 4000---> 1600

Y/N: I set a card and end my turn.

Student 2: Draw! I activate Fusion Control! This lets me use a monster on your field to fusion summon. I now activate Polymerization! I fuse your Archfiend Black Skull Dragon with my Alestar the Invoker to Fusion Summon! Invoked Beast Caliga!

A fiendish monster appears.

(Caliga Level 4 Def 1800)

Student 2: I set a card and end.

Yuya: Draw! With my Pendulum Scale, I Pendulum Summon again! Time for an encore, Odd-Eyes Pendulum Dragon! Yuya: Rune-Eyes Pendulum Dragon! Attack Invoked Beast Caliga!

The dragon blasts the fiend.

Yuya: Rune-Eyes can attack again thanks to his effect! Destroy the face down Shaddoll Falco!

Student 1: Since Falco was flipped up, I can summon Shekhinaga in face down defense mode.

Yuya: I end my turn.

Student 1: Draw! I activate Shaddoll Fusion! I fuse Shaddoll Dragon with Light Hex-Sealed Fusion. I Fusion Summon, El Shaddoll Contruct!

A gigantic monster with thousands of strings coming from its back appears.

(El Shaddoll Contruct Level 8 Atk: 2800)

Student 1: Now Dragon destroys your face down! Now Contruct, lay waste to Rune-Eyes Pendulum Dragon! And since your dragon was special summoned, it's automatically destroyed!

Threads wrap around Rune-Eyes and they cause the dragon to explode.

Yuya: Rune-Eyes!

Student 1: I end my turn with a face down.

Y/N: Draw! Time to rock. First, I activate Foolish Burial! I send Red-Eyes Black Dragon to the Graveyard! But now I activate Red-Eyes Ritual! I Ritual Summon! Red-Eyes Ritual Dragon!

Your new dragon appears and it and Odd-Eyes roar in sync. Suddenly, you feel pain in your chest and Yuya is the same.

Y/N: I now use Yuya's Pendulum monsters to Pendulum Summon! Meteor Dragon Red-Eyes Impact! Now I normal summon Dread Dragon! I tune Meteor Dragon Red-Eyes Impact with Dread Dragon to Synchro Summon Stardust Spark Dragon! I now activate Red-Eyes Ritual Dragon's effect! I banish Red-Eyes Fusion from the graveyard! Now your Construct loses 1000 attack points while my dragon gains 1000 Atk! And another thing. Your monster loses its effects!

(Construct Atk: 2800----> 1800)

(Red-Eyes Ritual Dragon Atk: 2500---> 3500)

Y/N: Attack, El Shaddoll Contruct with Scorching Inferno Fury!

Your dragon completely destroys Construct.

Students' LP: 1600---> 0

The two students are warped back to Duel Academy. You look at Yuya and see the purple haired boy from before.

Y/N: Yuya, who is that?

Yuya: You can see Yuto?

Y/N: Yuto?

Yuto: That's me. I'm Yuya's Xyz Dimension counterpart.

Y/N: That explains the similar faces but why can I see and hear you?

Yuto: I don't know. Only time will tell I suppose.

Meanwhile...

Leo: He is getting too powerful... He needs captured. Call in the Tyler Sisters!

Worker: Right away, sir!
