Sorry if this seemed like really lazy filler. Like I said this is my first fan fic and I'm still trying to figure out where I'm going with this. I would really love your feedback.
"I can't believe he's gone.", Yuma says as he looks at the ground in hopelessness on his knees. He then gets back up with an angry look on his face and yells, "I swear to you, whoever you are, I will get Astral back and defeat you!" "Yuma don't you think we should see how Vector's doing first?", Shark says. Yuma replies in a sad tone, "Right. Sorry. Got carried away there." Shark says, "It's alright. Now come on let's get him to a hospital." Then, Yuma feels something. Like a terrible power has just made it's way to the rest of his body. Then, all of a sudden, a voice says, "That's not gonna happen."
Then, the unconscious Vector disappears. Shark exclaims, "Where did he go!?" Then, all of a sudden, Yuma says, "You fool.", with a smirk on his face. Shark says, "What was that Yuma?" Then Yuma replies, "You don't get it do you? That Vector's a fake. I tricked you this whole time." Then Shark says, "Wait. You're not Yuma." "Excellent deduction Shark. You should be a detective. Or should I call you Nash?" Shark replies, "I don't know who you are but you better let Yuma go this instant!" The one in control of Yuma's body says, "You still don't know who I am? I'm the one who the little twat was dueling earlier. You know, the one who took Astral not even five minutes ago?" Shark replies in an angry tone of voice, "I don't care who you are! If you don't let Yuma go then at least tell me where the real Vector is!" The stranger replies, "He's with me. As are the rest of the filthy Barians except you obviously." Shark replies, "You are aware I'm not a Barian anymore right?" "I don't care what you are! That doesn't erase the sins of your past!", the stranger says in an angry voice. Shark says, "What do you know of my past?" "Oh, everything. You know how? Because I was there when you tried to make the three worlds become one Nash. I was there when they almost collided. But there's something you don't know about that incident." Confused, Shark asks, "Yeah!? And what's that!?"
The stranger replies, "That there was a human who got infected by the powers of both Astral World and Barian World." Shark replies, "What are you talking about!?" The stranger says, "Before the three worlds were stopped from colliding, I was caught up in all the chaos. I was in the middle of Heartland City when they fused. I was confused and curious, so I decided to take a better look of my surroundings. Then, I saw you and Yuma dueling Don Thousand. I was so captivated by the duel, I just had to stick around. Then, that's when you ruined my life! When you tried to fuse the three worlds their powers collided into me as I was caught in their crossfire! I became part human, part Astral, and part Barian!" Shark gives off a look of surprise. The stranger continues telling his story, "When this happened, the two powers went absolutely out of control! It was like they were trying to destroy each other. It was the worst pain I ever felt for three years! Once I learned to control them, I went after the Numbers. And now we're here. You see now? You caused me more pain than I've ever felt Nash! And because of that not only am I gonna take the Numbers but I'm also gonna get rid of you and the rest of you filthy Barians for good!" Shark replies, "And what will happen once you get your revenge?"
The stranger replies, "Why, I'll cleanse this world of Astral World as well." Shark says in surprise, "Astral World? Why go after them?" The stranger replies, "Because they're the ones who started the war between Astral World and Barian World in the first place! If they had embraced chaos like they should have instead of banishing it, then there would have been no war for the Numeron Code! It's their fault! And so I will destroy Astral World as well so only Earth will be left standing! However, in order to do this, I must acquire the Number cards, including the ones in your possession." Shark replies, "You're a maniac." "No, I'm just someone who'll do whatever it takes to achieve their goals. Now if you'll excuse me, I'll just take this body and I'll be off", the stranger says as he teleports away.
