I don't own Dragon Ball, Kimetsu No Yaiba and Doctor who. Dragon ball is owned by Akira Toriyama and Kimetsu No Yaiba is owned by Koyoharu Gotouge.
Last time Goku has been surrounded by Daleks and Upper moon demon one has entered the village.
Chapter 5: Wipeout and more invasions:
Exterminate! Exterminate! Exterminate! All Daleks including the Special Weapons Dalek all shoot at Goku. Goku shielded himself with a Ki Barrier. The Daleks go the Doctor has been detected. Seek, Locate, exterminate. The 11th, 10th and 13th Doctors all go not good! Goku blasts and destroys the Special Weapons Dalek.
Upper moon Demon one sees Goku and engages. Goku off course notices and engages. Upper Moon one is about to go moon breathing but is shot in the back by a Dalek. Goku blasts the Dalek destroying it and turns to the other Daleks. Goku dodges a sword strike and goes oh so your still alive. Well I soon fix that. Goku grabs upper moon one throwing him in the air and blasting him with a Kamehama which leaves no cells left. At the Infinite Fortress muzan is shocked at the lose of upper moon demon one. Muzan now believes that he can't do anything about Goku. Goku is staying on guard against the Daleks at all times.
Back at the Demon Slayer Corps:
11th Doctor says well I see that Goku has this under control. Both 10th and 13th Doctors says agreed! 13th Doctor says well we better take Goku back home after this is over with. Shinobu asks what do you mean back home? Oh wait I just remembered you earlier said he's from a different dimension. Everyone else asks how did Goku easily kill Upper Moon Demon one with no effort? The 13th Doctor says it's because Goku has enough power to destroy like two and a half to three solar systems. Nezuko asks well this is way different from my dreams.
Back on the Battlefield:
Goku thinks he has destroyed all of the Daleks but some have escaped by using emergency temporal shift. Goku doesn't return to the Demon Slayer Corps. Instead Goku uses Instant transmission to go straight at Muzan. Muzan is shocked my Goku's arrival. But Goku doesn't know about Muzan's seven hearts and five brains and insane regeneration speeds. But that doesn't matter because of one technique the solar flare. But Goku wants to battle fair. Goku thinks that it's still one sided in his favour but if Muzan scratches Goku, Goku would become a Demon. Goku dodges Muzan's attacks with ease and lands punches and kicks at Muzan's gut, shoulders, legs and head. Goku is surprised at how quick Muzan heals. Goku did fly away from Muzan and kill the rest of the Demon Moons with ease. He goes back to Muzan.
A portal has opened and it goes back to the same Dragon Ball Universe that Goku came from. Muzan falls through the portal and it closes. Goku goes dammit that was my way back home and I missed it. And even worse Muzan fell through the portal and to make matters worse I see it has night time at home. Muzan goes where am I what is this place. Is this the future because everything is advanced? Well I better hid my energy.
Goku returns to the Doctors using Instant transmission. Goku informs the Doctors and the Demon Slayer Corps what a happened. The 11th Doctor says well that aren't good he might start causing cause on your Earth! Goku says I am pretty sure that Vegeta can handle it.
Vegeta senses something. Bulma goes what's wrong Vegeta? Vegeta says I think I sensed some negative energy it doesn't seem like much of a threat but I better go and check it out incase. And after all Goku is still dead in the afterlife. Vegeta goes okay what ever it is it's hiding it's ki.
Kimetsu No Yaiba universe:
Someone comes up to Tanjiro and Nezuko and she says that her name is Emily and something isn't right and she also says aren't you Nezuko meant to be a Demon? Nezuko says I have memories of being a demon! Tanjiro says wait Emily your scent tells me that you're a demon! Emily says you are right but my cells work against Muzan Kibutsuji's cells. I can even turn a newly turned demon back into a human if they have been a demon for less than three days. But I have memories from other timelines and Son Goku is involved in a lot of them. But I know that the Doctors are only involved in two. Emily also says because of the change of events in the timeline has somehow allowed her to be in the sun. Emily is shocked to hear that Muzan somehow has gotten trapped in Goku's universe.
Emily says I know that this timeline is all wrong. The 10th Doctor appears and says time doesn't travel in a straight line it's like a big ball of timey wimey stuff. Emily goes who are you? 10th Doctor says I am the Doctor and what's your name? Also I know that you are a demon! She says my name is Emily and how can you tell that I am a demon? 10th Doctor says I can feel it and I scanned you with the sonic screwdriver. Emily says my cells work against Muzan's cells and I know that Muzan is trapped in Goku's universe some how. Goku appears by using instant transmission shocking Emily. Emily says I have been involved in events from another timeline. But my time is running out. The 10th Doctor says I may be able to help you live a bit longer. Goku says you can accurately do that? 10th Doctor says well of course I can I am so smart!
13th Doctor is in the Tardis trying to track down Muzan and finds him in Goku's Universe but is unable to lock on. 10th Doctor arrives at the Tardis with Emily. 10th Doctor says any luck finding Muzan yet? 13th we Doctor replies by saying yes but I can't lock on to him! 13th Doctor says hey Emily I see you met my other self. Emily goes oh so our both the two Doctors. Tanjiro and Nezuko are both in the Tardis walking around shocked. Emily bumps into Tanjiro and Nezuko. They start talking again.
Dragon Ball Universe:
It's night time so Muzan has decided to go out for a walk. Vegeta lands and says hey you you're new here and you also look lost. Muzan says well I am new here I only arrived here yesterday! Vegeta says you seem stronger than all of the humans! I want to test your strength! Muzan agrees to this. Muzan thinks (this should be easy). Vegeta thinks (I know this guy isn't human. Actually I don't know what he is! But he doesn't stand a chance unless he can regenerate.). Vegeta goes in for the first punch which connects. Muzan tries to hit Vegeta back but can't land a single hit. Vegeta goes a bit to far my landing punches that would even kill Tien or Krillin. Vegeta is surprised that Muzan has survived the attacks and has quickly healed from then.
Night is coming to an end and Muzan stops the match. Vegeta says why are we stopping? Muzan says I am sorry but I am allergic to the Sun. A puzzled Vegeta goes wait your allergic to the Sun? Muzan says yeah sorry about that. But another Wormhole appears and Muzan falls through it and ends up back home in the infinity fortress but Vegeta also falls through the wormhole. The wormhole closes and Vegeta managed to get out of the fortress before he got trapped. Vegeta goes wait I sense Kakarot's ki. Vegeta flies into Goku's direction. Goku is shocked to see Vegeta. Vegeta asks who are these people? Tanjiro and Nezuko both introduce themselves to Vegeta. Vegeta says well at least your both friendly. Now where is that guy I met? Goku asks who? Vegeta says he had red eyes, curly hair, smart close, fangs and sharp nails! We ended up here through a wormhole! Goku asks did he say his name? Vegeta says of course he did Kakarot he said it was Muzan Kibutsuji!
Goku says Vegeta that guy is an enemy demon that we are trying to kill! Vegeta says how was I meant to know that! I just learnt that now you clown! Tanjiro and Nezuko both ask who is Kakarot? Goku says fine my birth name is Kakarot but my Earth name is Son Goku and I only allow Saiyan friends to call me Kakarot everyone else calls me Goku!
Nobody knows that in the Dragon Ball Universe at someone managed to find new Namek and use the Dragon balls to bring back sell so he can do the dirty work of getting rid of Gohan and Vegeta. He also wishes Cell to Vegeta's location but doesn't know that Vegeta is currently in another Dimension.
Goku decides to teach Vegeta the fusion dance incase they ever need to fuse Goku did convince Vegeta by showing how the fusion works along with the power boost. He does this by having Tanjiro and Nezuko both fuse with the dance. But Tanjiro and Nezuko both get an extra compatible boost making the fusion more powerful. Goku and Vegeta fused would have a rival boost which isn't has big has the compatible boost.
Quick explanation between the different of the compatible boost and rival boost. Compatible boost on Tanjiro and Nezuko is times an extra ten has the rival boost between Goku and Vegeta is an extra times five. Plus with no God Ki potara Fusion is ten times more powerful than the dance.
Tanjiro and Nezuko fusion says I am called Neziro. Goku says also Vegeta please remember that the fusion dance long last half an hour. Vegeta says well all that matters is that it isn't permanent and I would only do it in a big emergency when needed but has long has no sees us doing the dance understood Kakarot! Goku says I understand! Goku and Vegeta are now both worried since they both now sense Cell.
Vegeta goes dammit someone revived Cell and sent him after me! Goku says well I have a new transformation. Vegeta goes what Super Saiyan two you mean Kakarot! Goku says wait you also have the form too! Vegeta goes of course I did you clown and I part trained with your son a bit to obtain it. Goku says this is bad it feels like Cell has gotten ten times stronger! Vegeta painfully goes well we might have to work together against him! Goku says yeah no messing around! We might have to fuse Vegeta! Vegeta painfully goes dammit we might have to.
Tanjiro's and Nezuko's fusion says call me Neziro and how long does this fusion thing last? Goku says it only lasts for thirty minutes but you can shorten it with Kaio-ken if you want! Tanjiro's and Nezuko's fusion ended lasting the full thirty minutes. Tanjiro and Nezuko both say that was weird sharing the same body! Tanjiro says I also saw those dreams you were talking about Nezuko and I am part freaked out by it. Goku goes Vegeta! Our fusion wouldn't last the thirty minutes in Super Saiyan and Super Saiyan Two.
Emily appears and says I want to try that fusion myself if I can! Goku says but both people fusing have to have their power levels at the same level. But I do think that after that the fusion could power up to both uneven levels times each over with what ever the extra bonus is if there is one!
Cell appears and goes oh it looks like I have to kill you again Goku and Vegeta too. Vegeta powers up to Super Saiyan Two charging at Cell. Goku also goes Super Saiyan Two charging at Cell. Cell easily dodges and blocks Goku and Vegeta's attacks. Cell punches Vegeta so hard knocking Super Saiyan Two out of him. Goku tries something dangerous. He goes Super Saiyan Two Suppressed Kaio-ken (times 1.5). But Cell easily beats Goku and says well Goku has improved the most but not has much has me! Goku goes Vegeta! Cell goes well time to destroy the planet. The Doctor appears in the Tardis and uses the Tardis shielding to protect the area. Cell is annoyed that a blue police box randomly appeared and shielded his shots.
Vegeta goes I can't believe I am going to fuse with you! Goku says it's the only way to beat Cell! Tanjiro and Nezuko both have gotten into the Tardis. Goku and Vegeta both go fusion ah. They managed to get the dance done properly in one go. Hmm I guess that Goku and Vegeta make Gogeta. Cell goes you think fusion is going to help you both don't make me laugh. Gogeta powers up to Super Saiyan. Cell goes very well and goes full power. Gogeta is easily dodging and blocking Cells attacks and is landing damaging blows to Cell. Cell goes right I have had enough of this and goes full power and also goes Kaio-ken times twenty. After Cell has gone Kaio-ken times twenty him and Super Gogeta are going toe to toe until Gogeta goes Super Saiyan Two.
Cell goes from times twenty to times twenty five. Gogeta throws the soul punisher and Cell is trying to hold it back. Gogeta says it ends near right now Cell! Big band Kamehama. Cell breaks free from the small attack and fires a super Kamehama and goes Kaio-ken times hundred. Gogeta goes dammit and also goes Kaio-ken times two on top of Super Saiyan Two. Gogeta pushes too Super Saiyan Two Kaio-ken times ten and over powers Cell. Cell is engulfed and destroyed with no chance of regenerating. Gogeta has defused. Goku says well Kaio-ken shouldn't be possible with any Super Saiyan transformation unless on Perfected Super Saiyan and Super Saiyan Two in a fusion I guess. Vegeta says thank god that's over with and I never want to fuse with you ever again Kakarot.
Muzan has spies and he was freaked out that he saw to people fuse and defuse. He also wonders what the bug looking creature was. Goku takes Vegeta to the Demon Slayer Corps with instant transmission. Shinobu says who is this Goku? Goku says oh it's just my friend but mostly rival Vegeta. Vegeta says well at least the humans here aren't weak. Shinobu goes what do you mean by humans? Vegeta says like Kakarot here I am a Saiyan but I am prince of all Saiyans well what's left of them. Mostly Kakarot, his sons, my son and my younger brother if he's still alive. Goku says wait Vegeta you have a younger brother? Vegeta of course you clown he saw sent away from planet Vegeta because he doesn't like fighting. Actually now that I think about my Father did exile a Saiyan called Broly but I don't know where he was sent to or if he is still alive.
Goku says another Saiyan called Broly? But we don't know if he's dead or alive. But we need to get back on task the of killing Muzan. Goku says I won't use the solar flare technique since I want to fight him with him at full power.
The 10th and 13th Doctors use the 11th Doctor's Tardis to charge theirs. They finally separated their Tardises . All three Tardises pick up dimensional time anomalies between multiple dimensions. All the three doctors start closing most of the anomalies before anything happens. But they didn't close one in time. The 13th Doctor goes dam we failed to close one in time! 10th and 11th Doctors go oh we have. 13th Doctor says that anomaly opened in space within another version of this universe and Goku's universe. This aren't good it was a Saiyan pod that when through the anomaly and landed in that other timeline of this dimension the pod landed in 1900 where not that far from where I found Goku and Tanjiro's home. Well we can't do anything to fix that sadly. We might has well help out this dimension. Wait more time anomalies have opened here and something has come through. All three Doctors at once go this is really, really bad Cybermen now.
Goku and Vegeta are both getting ready to engage Muzan. But a crow comes up to Goku and says emergency, emergency. Another village is under attack by different unknown beings. Other Hashiras and Slayers have arrived there already. Goku goes Vegeta let's go. Vegeta goes fine has long as we fight this Muzan guy afterwards. Goku uses instant transmission to go to Tanjiro and Nezuko who also been informed by their crows. Goku uses instant transmission teleporting himself, Vegeta, Tanjiro and Nezuko to the village where the Hashiras are. Goku, Tanjiro and Nezuko say right where here.
The Doctors appear in their Tardises. 13th Doctor says they are Cybermen and they are people but in a metal shell that you see. Vegeta says let's get this over with. Vegeta moves out and says hey Cyberdorks over here! Goku moves in. The Cybermen aim there weapons at Goku and Vegeta and fire with no affect. Goku and Vegeta start destroying Cybermen left, right and center with ease. Until the Cybermen go upgraded. Goku and Vegeta's attacks are no longer working. The 11th Doctor says they have adapted to Goku and Vegeta's attacks. They might be in trouble now.
Goku and Vegeta have managed to get the Cybermen all together in one place to be wided out with one attack. Goku goes Super Kamehama and Vegeta goes Final Flash. The both fire and combine their attacks together. After a big explosion there's only one Cyberman left. The Cyberman teleports away escaping like the Dalek. 10th Doctor says oh come on! Now one Cyberman has escaped.
Goku and Vegeta disappear by Goku using instant transmission and they find themselves in the infinity fortress. Muzan is surprised to see them. Goku and Vegeta get ready to fight. They hear the sound of a musical instrument and Goku and Vegeta have been separated. Muzan says to Goku so you want to kill me is that why you're here? Goku says yes. Muzan says okay then let's begin.
TBC
(A/N)
Okay so the Cybermen have attacked and thanks to Goku and Vegeta that was short lived. But has said with dimensional time anomalies the doctors fail to close one in time. Yes a Saiyan pod has landed not that far away from Tanjiro's home in 1900. So that's going to be a separate story crossover. Kakarot arrives on the Kimetsu No Yaiba year 1900 and is found and adopted by the Kamado family. Also part Kimetsu No Yaiba AU with more than just one change.
Oh boy what am I doing with myself making a third and fourth story. The third one the five way crossover and this other story I have mentioned. So expect some delays since I am working on four stories part at a time.
