I don't own Kingdom Hearts or anything. ENJOY!
In a Dark place.
A boy by the age of 10 with brown hair wearing a white sweater, brown collor, black pants, red sneakers, and has grey eyes is in a dark place. Huh? W-Where am i? The boy thought. After he took a step the floor it suddenly glowed revealing a floor with a princesess on it. Soon a voice said "So much to do so little time... Take your time don't be afraid. The door is still shut. Now step foward. Can you do it?"
The boy walked to the center of the circle. Soon three altairs appeared each holding a shield, staff, and a sword. "Power sleeps within you. If you give it form... it will give you strength." The voice said. Who is this guy? The boy thought as he walks toward the sword. "Choose well." The voice said before the boy picked the sword up.
The voice said "The power of the warrior. Invincible courage. A sword of terrible destruction. Is this the power you seek?" Yeah i guess... The boy thought before the sword disappered shocking him. "Your path is set. Now what will you give up in exchange?" The voice ask. The boy looked at the shield and the staff before he walked toward the staff and picked it up.
"The power of the mystic. Inner strength. A staff of wonder and ruin. You give up this power?" The voice ask. Uh yeah? The boy thought before the staff disappered. "You've chosen the power of the warrior. You've given up the power of the mystic. Is this the form you choose?" The voice ask.
Yes? The boy thought before the altairs collapsed. Soon the floor disappered as the boy fell. The boy landed on another floor. Then the sword he picked appeared on his hand as the voice said "You've gained the power to fight." The boy slash and the voice said "Alright! You've got it. Use this power to protect yourself and others. There will be times you have to fight. Keep your light burning strong." Then people completly black and has glowing yellow eyes emerge from the ground.
The boy got himself ready and charged. One of the persons attempts to punch him but he slash the person in half. He slash the others in half before one of them got behind him. "Behind you!" The voice yelled as The boy slash the person in half. Then a door appeared. The boy went toward the door and he tried to open it but his hand went threw it. I can't open it. The boy thought. Then the door glowed before it became real.
The boy touched the door and opended it. It revealed an area with a girl and two boys. "Hold on. The door won't open just yet. First tell me about yourself." The voice said. The boy went to the girl and she ask "What do you care about?" "You." The boy simply said as she blush. The boy went to another as he ask "What's your goal?" "Make the world a better place." The boy said as the boy said "Mm-hm." The boy went to the other as he ask "What are you afraid of?" "Death." The boy said as the other fliched.
"You cared about that girl. Your goal is making the world a better place. Your afraid of death. Your adventure begins at dawn. As long the sun is shining your journey should be a pleasent one." The voice said. "Sounds good." The boy said. Then the voice said "The day you will open the door is both far off and very near." The entire scene then glows real bright before the boy found himself back into the dark place.
The boy looked at the light and walked toward it. Soon he found himself surrounded by more black people as he summons his blade. One rush toward him and attempt to grab him but the boy rolled out of the way to dodge. The boy slash the person's head off as he disappeared into a black mist.
Two more charged but the boy jumped and kicked them away. Then the boy slashed at one killing it. Then he spin around slashing all of them in half. Soon a stair case came out. The boy ran toward the steps and stops on the middle of a new floor. "The closer you get to the lithe the more powerful your shadow becomes." The voice said as The boy looked behind him.
The shadow on the lifted itself off the ground and started to change. The shadow looks like a giant devil, with three glowing eyes, completely black, heart shaped hole on the stomach, long fangs, spikes on his back, arms, and legs, short legs, muscular arms, claws on one hand and holding a short axe, horns craved into long short spirals, short wings, a small tail looking like a bone, and a long bone on the wings.
The boy stepped back in shock as the shadow grew. "But don't be afraid and don't forget..." The voice said as the boy ran toward the stairs but they disappeared causing him to stop. The boy look at the shadow beast walking toward him. I guess i can call that thing a Vanguard. The boy thought as he summons his sword.
The Vanguard did a downward slash with it's axe but the boy rolled out of way as the axe hit the ground. As the Vanguard struggled to pull the axe out of the ground, the boy ran toward his back and slashed he kept slashing before The Vanguard pulled the axe out of the ground. The Vanguard used his wings to fly up a little and stopped as he dropped to the ground resulting a large shockwave and pushing the boy back. The Boy jumped to his feet and rolled out of harms way as The Vanguard tried to slash twice but kept missing.
Too bad for the Vanguard's speed. He's so big he's too slow. The boy thought. "Oh really? Will let me lower my size a little." The Vanguard unexpectedly spoke shocking the boy. The Vanguard shrink down a little. The Vanguard slashed twice as the boy dodge them but with much difficulty. The boy ran toward one of The Vanguard's legs and slashed. The Vanguard slashed as the boy dodged it but then The Vanguard smacked him away.
The boy did a few backflips before he landed on his feet The Vanguard uses his wings again and landed hard causing another shockwave to happen. The boy was blown back. He landed with his back on the ground. The boy was lucky he rolled out of the way when The Vanguard did another downward slash and his axe once again got stuck to the ground. The Vanguard begins trying to pull the axe out of the ground as the boy went to slash his back again. As he slash The Vanguard turned his head and fired a fire breath. The Boy rolled out of the way as The Vanguard pulled the axe out.
The boy got on his feet before the sword disappeared shocking him. Are you kidding!? Not now! The boy thought as he runs. The Vanguard grabbed him and said "But don't be afraid." The boy recognize it as the voice. "You... you want to kill me?" The boy ask in fear. "No i'm just preparing you for the worst to come. You hold the mightiest weapon of all. So don't forget: You are the one who will open the door... Scotty." The Vanguard said as the darkness around Scotty surrounded him.
Then he's vision turned dark and he can't see anything.
There you go tried to make the fighting scenes big and FYI i know the heartless can't speak but for this one they can. Scotty looks like Roxas but a few differences.
