Saitama is evil

Due to constant betrayal and human greed saitama heart became hollow and he started to doubt his existence

so when people start killing each other continuously so saitama became angry and he could not believe it so he thought maybe gaoru was right and this so called hero concept does not work anymore so he became rogue and started killing people who use people for their benefit

but soon he totally loses his sanity and start killing innocent people so god of that dimension became worried so he decided to sent Saitama to another dimension without informing other gods because he can't defeat saitama

GOD- I think I should send him to that dimension where chakra and ninjas reside

then he made preparation and open a portal and send saitama to another dimension

now saitama was very angry he cannot keep calm he wanted to erase humanity but now his entire consciousness went into some strange dimension

Saitama - I wil not let you get away with this and soon punched his way into the cosmos and entire cosmos shattered and he came into a forest

saitama - where am I what is this strange place

and by this he was transferred to naruto universe
