Chapter 3: The end of a world

Destiny Islands / Destiny Islands day two (night)

Sora and Ben were in Sora room's to rest for tomorrow's departure, but Ben was worried about what he had heard from the hooded guy that this world was about to be taken by darkness, not knowing what he wanted he began to rethink the idea to leave with his new friends to protect the island from what would happen, while Sora was constantly moving and then turn his gaze to a corner of his room where there was a ship hanging from the ceiling with two puppets on it saying :

Sora: I can't wait. When we set sail, it will be great.

Then she drew his attention out the window

Sora: A storm?

This got Ben out of his thoughts looking at the window with him.

Ben: Sounds very cool, Sora did you remember to tie up the raft in case there was such a situation?

Sora got out of bed with his eyes open and in fear

Sora: Oh, no, the raft!

Ben: I knew, let's hurry up… ok?

Sora's Mom: Sora, Ben, dinner is ready. Come down. Sora? Ben?

She didn't get an answer from either of them because there was no one in the room anymore, just an open window.

On the outside

Sora: What is that?

Ben looks up to the sky to see a huge black and lightning ball.

Ben: I don't know, but it has a threatening aspect.

Sora: Riku's boat! And Kairi's!

Then suddenly small black creatures with curled antennae and two yellow eyes began to emerge from the ground, Sora in seeing them was frightened because he thought that those creatures only lived in his dream, then he took the wooden sword and began to fight them while Ben decided that he would have fought them with kicks and punches, because if he would have turned into an alien he would have surely frightened Sora and made himself see as an enemy. When Sora and Ben began to attack the strange invaders they noticed that none of their blows had any effect on them, besides being numerous they were also very strong and also quick in giving them.

Ben: Sora uses the your weapon like when you beat them the last time.

Sora: What? How do you know I've dealt with them before? Also I don't even know what this thing is?

Ben understood that Sora thought it was only a dream that battle he had faced along with that monster with the tentacles around his head, so he thought of a better idea.

Ben: Let's run away! They are too strong for us, we need to find the others and see if they are okay.

Sora nodded yes, after the strange beings left a free space immediately both fled, hoping to find a safe place in doing so but Sora and Ben saw Riku on the islet connected to the bridge but it was as if they didn't noticed the chaos on the island so they both headed towards him to ask if he was okay and where Kairi was, but when they reached him:

Sora: Where's Kairi? I thought he was with you!

Riku: The door has opened …

Sora: What?

Hearing that sentence Ben remembered what the hooded guy had said, then realized that the one in front of them was not Riku talking.

Riku: The door has opened .. Now we can go to the outside world!

Sora: What are you saying? We need to find Kairi!

Riku: Kairi is coming with us! Once we pass there, we may never return. We may never see our parents again. He is not going back. But it is perhaps the only possibility. We cannot hesitate! I am not afraid of the dark!

Sora: Riku …

Ben: Sora! Don't listen to him, that's not Riku.

Riku begins to descend into the hole of darkness as he holds out his hand to both of them, Sora tries to take Riku's hand as he too begins to get sucked in, then Ben immediately runs to both of them and tries to get them out ending up in the hole of darkness as well. The darkness began to engulf all three until total nothingness remained. Suddenly there were two flashes of light, one white and one green that pierced the darkness, when Sora opened his eyes he noticed that in his hand instead of having his wooden sword he had a key-shaped sword that seemed to be made of silver and gold with the crown symbol that he had on the necklace at the top and a pendant with the symbol of the King tied to a chain on the back of the handle, Sora when he saw it was surprised as if he had already held that weapon before, but then he was distracted by a voice on his right that said:

?: At least it couldn't get any worse than that.

Sora looked down slightly and that made him very confused than he had ever been confused in his entire life, next to him was what looked like a beaver standing on two feet, with four-fingered hands with gloves, with a head-to-toe black and green dress with a long mustache under the nose and two long beaver-like teeth and two large green eyes, with the omnitrix symbol on the belt.

Sora: And you ...? Who or what are you? What happened to Ben? I'm not crazy .. am I? (Moving away from the strange creature a little.)

?: Let's say it's a bit complicated to explain but you just need to know that I'm on your side and that I don't want to hurt you, don't be afraid.

Alien Bio ...

Name: Mole Mustache (Molestache)

Race: Unknown

Description: Mole Mustache (Molestache) is an alien placed in the Omnitrix by Blukic and Driba. It is similar to a beaver or a mole that can burrow like moles and stretch its whiskers to use them as hands, turn them into a helix, etc ... Females of the Mole Whiskers species rely on their braids to fight, obviously being devoid of mustache.

Sora stopped because of a strange voice that only he could hear coming from the sky, and when he raised her head he heard it more clearly:

?: Keyblade ... Keyblade ... Keyblade ... Keyblade ...

Then the two were surrounded by the yellow-eyed creatures and both stepped back to back to fight them.

Ben (Mole Mustache): If you still don't believe me I'll help you defeat these things so you can trust me.

Sora: Okay… I think? (with an expression of doubt)

The creatures with yellow eyes began to attack Sora in a group but with the slashes of the Keyblade he managed to make them disappear in a cloud of black smoke, while the other half attack the strange mole more numerous, but suddenly the mustache of the creature became larger first to form two fists that began to hit all beings making them fly away and then make them disappear in the cloud of black smoke.

Ben (Mole Mustache): And that's what happens when you blindly challenge a beaver.

The two continued to fight their way through the enemies to be able to find Kairi, but wherever they went the creatures became more and more numerous and Ben knew that the omnitrix wouldn't last long yet, he had to help Sora and find a place where he could transform back into human. , it was then that an idea came to mind:

Ben (Mole Mustache): Look if your friend if she's out here, where she might have gone looking for shelter to save herself from such a situation?

Sora thought for a while and then figured out where Kairi would be hiding in the event of such a thing.

Sora: We are our secret place, follow me I will show you the way.

Ben (Mole Mustache): Okay

The two managed to reach the place quickly but noticed that at the entrance there were no longer plants to cover it but a door that seemed to be there recently, both wondered what it was doing but found no explanation, when Sora opened the door. door hoping it will lead to the cave noticed that the strange being who had helped him stood with his back to the door as if he had noticed something wrong:

Sora: What are you doing, hurry up and get in.

Ben (Mole Mustache): I can't those things that look like shadows are coming, I have to defeat them if we don't want them to follow us.

Sora: What? You can't do it alone, it could become too much for you.

Ben (Mole Mustache): Remember you are looking for your friend, and also your friend Ben, he's out here I have to look for if you don't want to lose him too.

Sora realized he was right, both Ben and Kairi were in danger and he had to find them if he didn't want to lose them too.

Sora: Okay, please find Ben and bring him here.

Ben (Mole Mustache): Don't worry I'm a hero after all and that's what heroes do.

Sora: Are you waiting for a hero? But what is happening today? (Confused)

Ben (Mole Mustache): I'll explain later, now think about finding your friend.

Sora did as he was asked leaving everything in the hands of those who had just called themselves a hero hoping that he will be able to find Ben.

In time on the other side of the door ...

The enemies were starting to arrive at Ben in larger groups and everyone's target seemed to be the door behind him, the enemies began the assault but unfortunately some were hit by the whip of mustache that Ben had created to strike more targets at the same time, forcing them to retreat a few steps.

Ben (Mole Mustache): Is that all you know how to do? And to think that I had some difficulties before, now I understand how it works, if the quality is poor then focus on quantity, you want to know something? I know how to do this too and now you will understand the ...

He was interrupted by a familiar blinking sound and green light that when they finished there was a light that when he went out brought Ben back to his human form.

Ben: Why did you dump yourself? I still need you. (Looking at the omnitrix)

Then I look at the enemies as he headed for the door:

Ben: Eh..eh… hey guys, can we talk about it?

The creatures after what they had seen were still as if they had seen a ghost, taking advantage of the opportunity Ben, opened the door and in a flash closed it, when he entered he began to run up to the depth and when he arrived, he saw both Sora and Kairi, luckily they were fine but there was no trace of Riku.

Sora: Kairi!

When Kairi turned they noticed that she was sad

Kairi: Sora ... Ben ...

After calling them the door behind her opened letting in a strong wind and black smoke, then Kairi was carried by the wind towards Sora, when she noticed him she tried to catch her but she couldn't because I pass through her like a ghost then to a Once the wind from the door became strong enough to blow Sora and Ben away. When they recovered their senses they noticed that they were outside but they found themselves on a piece of the island that was under that huge black sphere and suddenly they heard a huge stench from behind them and when they turned to understand what it was , they could not believe what they saw. Behind them was the giant monster with tentacles around its face and they both realized they had to fight if they were to survive.

Sora: Do you know where that beaver monster who rescued you went? Because I'm not sure I can do it.

Ben: You mean Mole Mustache? I do not know.

Sora: Does it even have a name now?

But they both did not realize that the monster in front of them had begun to attack them with black spheres coming from the heart-shaped hole of his belly, when they noticed Sora sliding in front of the creature because he remembered that he had to attack them. hands to beat him as he had done the first, while Ben hid behind some debris and thanks to Sora who kept the monster busy Ben activated the omnitrix by scrolling the playlist until he found the hologram that needed them.

Ben: Ok omnitrix, I hope you're generous this time, because I need a big favor, a waybig favor.

Sora was starting to be tired because the energy balls did not give him a breather, not having time to parry the last balls that the monster had launched he thought that the end had come, when the balls hit the point where he was Sora creating a huge pile of smoke, the monster thinking he had won got back on his feet but for some reason he could not, looking for the cause of the problem he noticed with what seemed like extreme horror that his wrists and feet had been blocked by those that looked like teal-colored crystals, not understanding how and where they came from, tried with every effort to get rid of them but could not, then from the huge pile of smoke came other splintered crystals that hit the monster's chest capturing his attention looking at the point where he had defeated the owner of the Keyblade, when the smoke dissolved it revealed a huge dome made of crystal from which emerged a creature made of that material that held Sora, he was very tall in black and green clothes, with two very long crystal shards protruding from the back of his shoulders, green eyes and the omnitrix symbol on his belt.

?: Hey squid face hasn't anyone ever told you that you shouldn't raise your hands on kids?

Sora when he opened his eyes and realized he had survived not knowing how, when he looked ahead he found himself a huge crystal being, facing the monster.

?: You're okay boy, thank goodness I made it in time otherwise you wouldn't have saved yourself from becoming a pile of dust.

Sora: Thanks! (Smiling) But who are you and where is Ben?

?: Rest assured I'm a hero and your friend is safe. I see you have a little bit of difficulty. Do you want a hand?

Sora: Yes please… what's your name?

?: You can call me Diamondhead!

Alien Bio ...

Name: Diamondhead

Breed: Petrosapien

Description: Diamondhead is a Petrosapien alien from the planet Petropia. Petropia was a crystal-covered world and its inhabitants are silicon-based life forms. The planet was destroyed by Vilgax with the help of Tetrax, who unknowingly helped him create the weapon that destroyed his home world. Created from an extremely durable crystal, Diamond is nearly invulnerable. Additionally, its sharp crystal body discourages physical contact, as sharp crystals can grow almost instantly from any point of contact and be retracted just as quickly. Diamondhead can also alter his own physiology, allowing him to regrow lost limbs as needed. Light-based weapons are also useless against Diamondhead, as his crystal body can act as a prism, refract light and beam-based weapons, and send them back to the sender. He can also scatter diamonds on objects to protect them. In attack Diamondhead can shape weapons with his body, and he can also shoot diamond crystals as projectiles. He can also grow diamonds on other objects. Diamondhead is also much stronger than a normal human being, which, combined with his self-modeled weapons, allows him to slice through any object with ease. The only drawback of the Diamond crystal shape is the crystal itself, which could shatter if exposed to sufficiently strong sonic vibrations such as Eco-Eco's sonic waves or if thrown against a hard object. While Petrosapien can regenerate lost limbs, there is a limit to how much damage they can take.

Seeing the owner of the Keyblade still alive in the monster was unleashed a destructive force such as to destroy the crystals that blocked his limbs getting back on their feet.

Ben (Diamondhead): He looks very angry, have you beaten this monster yet?

Sora: Yes, but before it was much weaker but now it seems stronger.

Ben (Diamondhead): And tell me how you defeated him?

Sora: When he attacks he always gets on his knees, first I attack his arms because he can also call out the little creatures that look like shadows and then I attack the head which seems to be the weak point.

Ben (Diamondhead): Good! I know how to act but I need you to trust me, okay?

Sora: Okay I'm there!

Just then the monster created a small sphere in his hand that hit the ground creating a black patch from which the small creatures that looked like shadows came out and began to attack Sora and Diamante.

Ben (Diamondhead): I'll take the little ones while you take care of the squid face.

Sora: Ok! .. Wait face from what?

Diamondhead started shooting small crystal fragments from his hands that hit all targets, getting many complements from Sora for the move that must hit the arms of the giant monster and when the right moment came the shots both, then the monster was about to hit Sora when From the subsoil some slabs sprouted that blocked the arm giving Sora the possibility to climb on it and hit the head (before however giving a fantastic and star eyes to Diamondhead for the move). When the chosen one gave the final blow the giant monster began to be sucked by the huge black sphere in the sky disappearing inside, but the sphere began to suck the whole island into itself, including Sora and Diamondhead who was testing. their grip which they lost completely and ended up being swallowed up.
