Dragon Ball Super, Dragon Ball Heroes and Kimetsu No yaiba Crossover
I don't own Dragon Ball and Kimetsu No Yaiba, Dragon ball is owned by Akira Toriyama and Kimetsu No Yaiba is owned by Koyoharu Gotouge.
Author Notes:
So in this story Son Goku is nerfed in the Kimetsu No Yaiba World but he is still way above all of the demons. He is weaken so he is easier for his old enemies cannon and non-canon to try and kill him.
Chapter 1
After the defeat of Zamasu and Goku Black the heroes started to rest and party but a wormhole with negative energy opens up and Son Goku is sucked through it. When Goku wakes up he started to wonder what happened and why he feels weak and can't sense any of his friends energy.
Goku senses 2 chi energies close by and 1 coming closer from a long distance but 1 of the energies is part faith and changing. Goku sees a house and wants to find out where he is and he's sees a boy panicking and then the boy runs off with a girl on this back. The boy is called Tanjiro Kamado and the Girl is called Nezuko Kamado.
Goku senses a change happening with the girl and starts to run after them but has he catches up with them he sees a guy with a sword trying to kill the girl. Goku sees the boy throw stones and a hatchet at the man and also sees the man knockout the boy and the demon girl breaks free and starts defending the boy and is also knocked out.
The man sees Goku and asks him to go with the boy and girl and says he will info him more after the boy wakes up.
After the boy wakes up the man introduces himself has Giyu Tomioka and he tells Tanjiro and Goku to go a see a man called Sakonji Urokodaki who lives at the foot of Mount Sagiri and to keep Nezuko out of the sun.
Meanwhile the two evil beings that created the wormhole want Goku dead so he doesn't stand in the way of their plans. Both evil beings have killed so many Super Saiyan 4 Goku's from other timelines.
End of Chapter 1
Author notes:
Additional information about Son Goku's nerf so in this the Wormhole has turned Goku back into a 16 year old and he's transformations are also disabled along with his ability to fly and use instant transmission. Plus the Super Saiyan god power Goku absorbed into his base form is also removed along with having no more access to god ki. Also his base form stats are also divided by super Saiyan 3 and halved. Don't worry goku still has access to the Kaioken but he can't use it for long.
Goku still has the potara earrings that he used against Merged Zamasu on him.
The next chapter is part going back to the Dragon Ball Universe with everyone going to try and use the dragon balls. Plus the start of Tanjiro's and Goku's training.
Plus I am also new to doing Fanfictions and feedback is necessary.
