Multiverse war ( Deku x crossover harem)

Yeah, I know this is the third time I'm doing something like this, but hey I like the idea that I came up with I think I might've ruined it when I added in so much about the spider-verse because I was kind of excited about beyond the spider-verse and when it got pushed back affected my writing so I think for this new one I'm just gonna avoid the spider verse as much as I can I will probably include some Spider-Man shows but they won't be as big as an impact as they were in the first one

When society collapsed and the hero community is in shambles izuku Midoriya a.k.a.deku goes on a rogue vigilante mission to stop all one also known as the Demon lord from destroying his world

But to do so he separates himself from everyone his friends, and his mentor and goes off rogue desperately trying to save society without thinking of himself unfortunately because of his self-isolation he did not realise that he fell right into the Demon Lord's trap

when he awoke, he found himself chained to a machine and the Demon Lord explained to him that he was going to use the ferocious power of one for all and all for one to create a black hole that would open to the Multiverse so that all for one could conquer it as his lust for power had continued to grow

The hero tries to escape, but when the machine is activated, both the hero and the villain dragged into the black hole....

and so the Multiverse war begins
