In the Shinobi World, Naruto gathered up the remaining Ash's team with Denki's team in the Hokage Room to give them a mission

Naruto: Thank you all for coming today, I got a mission for you all.

Denki: What is this mission about, Lord Seventh?

Naruto: Okay, first up is Pikachu, one of Ash's team member got taken by one of Orochimaru's experiment rat.

Sai: We recieve he was last saw near the Hidden Cloud Village, we can find them there.

Naruto: And also, the Eight-Tailed Jinchuriki, Octopops has gone missing.

Iwabe : The Eight Tails Jinchuriki, Killer Bee ?!

Naruto: Yes, I can guess this case got something to do with what happened to Pikachu.

Metal: This is interesting.

Naruto: And last, we got a report that the experiment rat is stealing a really dangerous experiment that has too many risk that can kill us all.

Ash: ....

Denki: So this mission is basically...

Naruto: Exactly, this is a rescue mission. You all need to rescue Pikachu and Octopops and take back the experiment. Understand?

All: Understand!

Naruto: Alright, and for Denki's team, Udon isn't in his well condition so he'll be replaced by someone else.

Metal: Someone else? Who could that be?

Suddenly someone burst into the door, it was Rock Lee while carrying his backpack with him.

Lee: Let the spirit of youth be with us!

Metal: Papa!

Naruto: *Groans* Yeah, Udon will be replaced by Lee. Although he did begged me...

Iwabe: Talk about bad timing...

Naruto: Alright, everyone understand the mission, right? So move out!!

In the Pokémon World, Sasuke lands down in the middle of a forest while panting heavily.

(Akami: Sasuke?! Are you alright?!)

Sasuke: My chakra...

(Akami: Huh?!)

(Seyaki: He's running out of chakra, he needs some time before he can be fully healed)

(Akami: What about the others?!)

Sasuke: We need to... rely on them... they'll find me soon... I just know it...

Meanwhile at the area where Chairo and Shiro is, the two shook themselve out of their pokéballs then looks around.

Shiro: Wh-Where are we?!

Chairo: I guess we're back in the forest again, but Father and the others aren't here anywhere!

Shiro: What should we do now?!

Chairo: I guess we need to find him somehiw, we have to try locating his chakra.

Shiro: I can try that.

Shiro made a hand sign while closing her eyes to locate Sasuke's chakra, but she didn't got any result.

Shiro: Sigh, nothing...

Chairo: What do you mean?!

Shiro: I guess Master Sasuke is too far out to be detected, I guess we just have to walk around to find him.

Chairo: That will take long actually, but I guess we got no choice huh?

Shiro: Alright then, let's go find him then.

Chairo: Yeah!

Meanwhile at the area where Kiro and Aoi is, the two shook themselve out of their pokéballs then looks around.

Aoi: H-Huh?! Where is everyone?

Kiro: It looks like we're lost in the middle of nowhere.

Aoi: What should we do?! We can't let ourselve lost!

Kiro: The only way to do that is to detect their chakra around here somehow, can you do that Sylveon?

Aoi: Of course I can, give me a minute.

Aoi made a hand sign while closing her eyes to locate other's chakra, but she didn't got anything.

Kiro: Well? Anything?

Aoi: No, I guess they are too far out to be reached by my detection.

Kiro: I guess we need to walk around this forest to find him somehow.

Aoi: You're right, let's go then.

Meanwhile at the area where Rai and Mizu is, the two shook themselve out of their pokéballs then looks around.

Rai: Wo-oh

Mizu: What just happened?! Where are we?!

Rai: I guess we got seperated from the others.

Mizu: How's that possible?

Rai: Maybe someone took our pokéballs and dragged us somewhere else.

Mizu: Oh no...

Rai: Don't worry, remember when Master Sasuke taugh you about chakra detection? Can you detect them somehow?

Mizu: Well... I hope it does...

Mizu made a hand sign while closing her eyes to locate everyone's chakra, but she didn't find them.

Rai: So?

Mizu: I-I can't find them!

Rai: Great, then I guess we need to wander around to find wherever they could be.

Mizu: Do you think that's possible?

Rai: Well we got no choice, right?

Mizu: *Sigh* Alright, let's go.

In the Shinobi World, Ash was running forward ahead of everyone followed by Lee, Metal, Sylveon, and the others.

Lee: Good Ash, you're speeding up! Show them the power of youth!

Metal: Let's go youth!

Denki: H-Hey guys? Can we slow down for a bit? I'm too tired...

Ash: *Frowns* Grrh...

Sylveon: *Frowns*

Sai: Ash, we can't force ourselve to run too fast like this. We're going to lose our energy to fight later.

Ash: I... I...

Lee: Ash, I have to be honest. But Sai is right, even know you got a lot of spirit of youth, we can't used it all up too much or our enemy will never taste our youth!

Ash suddenly stops that made the others do so, then turned around while looking at them with the saddest frown he can ever make.

Ash: YOU GUYS DON'T UNDERSTAND!!

Metal: Huh?

Ash: I have to find Pikachu! He's my very best friend in the whole wide world! He's like my very first friend!

Denki: Ash...

Ash: If I don't find them before it's too late, then he... he...

Lee walks towards Ash and put his hand on his shoulder.

Lee: Look Ash, I appreciate your spirit of youth ane how energetic you are on taking Pikachu back.

Ash: Yeah...

Lee: But I'm going to give you an advice, and that is...

Ash: Yes?

Lee: 1000 PUSH-UPS EVERYDAY!!!

Ash: Wait what?

Metal: YEAH!!

Everyone behind them started facepalming by the suggestion that Lee gives him.

Sai: I believe what Lee is trying to say is that you must have hope on Pikachu that he's going to be okay. I know you worried so much about him, but don't let that be the only reason you lost your energy just for him.

Ash: Okay... I'll remember that...

Lee: Thank you Sai, now let's go everyone! *Points forward* We got the youth waiting for us!

Metal: Yeah!

Everyone facepalms again while sighs heavily then everyone started continuing their run again.

Meanwhile inside a rocky room inside the ground, Pikachu woke up and found himself was tied up on a throne with chains around him.

Pikachu: H-Huh? Where am I?

Pikachu look around and saw Killer Bee's chakra was getting sucked by a mask while he was tied up against a chair.

Pikachu: Who? Who is he?

???: So you finally woke up huh?

Pikachu saw someone came out of the darkness, it was the mutant man that caught him before.

Pikachu: What the?! It's you!

???: Yes, I brought you here to bring the real master back into this world once again.

Pikachu: R-Real master?!

The mutant guy grabbed the mask that was sucking Killer Bee's chakra then he walks towards Pikachu.

???: This is a present for you...

Pikachu: What the?! What are you doing?!

???: Hold still, I'm going to put this on you and he'll be back.

Pikachu: No!! Get away!!

Pikachu tries to shock him away using thunderbolts, but there wasn't any attack that was effective since he wad electrical proof.

???: You'll help me restore him.

Pikachu : NO PLEASE !! NOOOO !!

He put on the mask on Pikachu's face that silence him then his head lowered unconsious.

???: Master... you better keep my promise...

In the Pokémon World, Sasuke was sitting on the grass uncalmly while refilling his chakra.

(Akami: It looks like you can't focus huh?)

(Sasuke: I know, I'm just worried about them. I don't know what will happened to them...)

(Seyaki: Have fate in them Sasuke, I'm sure they are going to be okay)

???: So you are Sasuke Uchiha?

Sasuke looked at the source of the voice and saw Giovanni was acrossed him with a giant metal box besides him.

Sasuke: Who are you? What do you want from me?

Giovanni: Let me introduce myself. I'm Giovanni, the leader of Team Rocket.

Sasuke: The leader of those 3 dorks? They are really hopeless if you asked me.

Giovanni: I... have to agree on you on that for once, but that's not what I after.

Sasuke: Then what do you want from me?

Giovanni: You've embarrased The Team Rocket, so I won't forgive you even for a bit. So I'll have to take you down right here, right now.

Sasuke: Oh yeah? What invention that you have this time?

The metal box besides Giovanni slowly opens by itself, revealing a robot of Sasuke himself.

Giovanni: Behold, Mecha Sasuke.

Sasuke: Huh?! Is that... me?

Giovanni: Exactly, if our inventions can't even take you down, then I guess fighting your own self would be enough.

Sasuke: I doubt that thing has the same ability as I am.

Giovanni: Oh really now?

Giovanni brings out a remote out of his pocket and turn out Mecha Sasuke, in a flash it appeared in front of Sasuke and kicks him away.

Sasuke: Graah!!

Giovanni: I upgraded Mecha Sasuke to be the strongest, deadliest invention in the whole world. And it will finally erase the mistake that you created.

Mecha Sasuke: You will end here, Sasuke Uchiha.

Sasuke: This... this can't be happening...

Chairo: This place... seems familiar...

Shiro: Huh? You know this area, Chairo?

Chairo: Yeah, it's... huh?

Chairo found a really big skeleton with a wound on it's head like it was axed by someone.

Shiro: Oh my goodness, who could've done such a mess like this?

Chairo: T-This...

Shiro: Huh?

She looked at his expression that turned into scared, like he saw a tragedy among the skeleton he just saw.

Chairo: This... this can't be him...

Shiro: Who? Who are you talking about Chairo?

Chairo heard someone pulling out am axe from a skeleton and they was running towards them.

Chairo: Shiro! Look out!

He kicked her away then jumps on the other side, finding someone almost axed them. They land down safely and looked at who was it.

Shiro: What the?!

Chairo: You...

A really tragic memory came into Chairo's head when he notice the one who almost killed them was the military man that killed his Father.

???: Well well well, seems like the little Chespin has finally grow up to be a real man.

Chairo: Y-You can't be alive!! You should've be dead!!

???: Zip it little one, when I'm done with you two, I'll keep on killing more and more pokemon until nothing is left.

Meanwhile with Kiro and Aoi, they were stopping near the river while washing their faces.

Kiro: Hey, Aoi?

Aoi: Yeah, Kiro? What's wrong?

Kiro: Have I ever told you about my past before?

Aoi: Hmm... I guess not. In fact, you never did tell us about your past.

Kiro: Well, until now, I'm holding a grudge on that thing.

Aoi: What thing?

Kiro: The dark spirit that possessed my brother. Because of that, he killed my parents and I was the only one left to help him, but I couldn't. I instead killed him by myself.

Aoi: Oh my goodness! That terrible!

Kiro: I...

Aoi noticed that Kiro's expression turned into total anger and sadness with tears and frowns following them.

Kiro: I'll never forgive it!! NEVER!!

He then started clawing the water from the river in anger and sadness while she is trying to calm him diwn.

Aoi: H-Hey Kiro, calm down. I hate seeing you like thi...

Aoi can feel a strange energy that cut her off while she is looking around at what she just felt. When she look back at Kiro, her eyes widen when she felt a really bad energy is consuming him.

Aoi: Huh? Kiro?

Kiro: I will never...

Aoi: Y-You okay Kiro? What's wrong?

Kiro: I wIlL nEVeR FOrgIVe yOu!!

Aoi: Huh?!

Kiro got up and wrapped his tail with the dark energy followed by iron tail, he swing it towards Aoi but she manage to dodge it.

Aoi: H-Hey Kiro! Calm down!

Kiro: YoU WILl dIe hERe RigHT NoW!!

Aoi: Wh-What happened to him?!

Kiro activates his curse mark to half state then he strikes his chidori towards Aoi.

Kiro: Chidori!!

Aoi: Kiro!!

But suddenly, a Shiny Lucario brought her away before Kiro can even strike his attack towards her.

???: That was close.

Aoi: Huh?! Wh-Who are you?!

???: My name is Edmund, and I see your friend is possessed by Dark Matter.

Aoi: D-Dark Matter?! What is that?

Edmund: It's like a dark spirit...

Edmund got cut out when he and Aoi avoided Kiro's thunderbolt.

Edmund: That possess someone through bad emotions like sadness, anger, and anything like that.

Aoi: So that's the dark spirit that Kiro was talking about...

Edmund: Look out!!

Edmund brought Aoi away before they got hit by Kiro's thunder.

Meanwhile with Rai and Mizu, they come across the dark part of the forest.

Mizu: This place seems familiar...

Rai: You're telling me, this place is not safe alright.

Mizu: Do you think it's possible for us to find the others?

Rai: We have to believe in them, and we have to believe ourselves.

Mizu: You're right

Rai: Good, now let's go before it's dark.

But then they could hear so many noises of robots around them that made them kinda afraid.

Mizu: D-Did you hear that?

Rai: Yeah, I think something sorrounded us...

Then they could see around them is so many of Team Rocket's failed inventions around them.

Mizu: What the?! Aren't they the inventions that Master Sasuke has defeated?

Rai: Whatever it is, I guess they won't leave us alone.

One of the robot that was using hydro pump hopped forward towards Mizu, she then uses her ice power to stop it.

Rai: I guess they won't show mercy.

Mizu: Yeah! Let's take them out!

Edmund: The only to free him is to purify him!

Pikachu: How dare you interupt my slumber!
