Spider man into the fandom verse (on Hiatus)

In hopes of saving his mentor, Tony Stark, Peter Parker decided to build a machine that could open up different realities. Of course he would have to be careful, after what happened with Miles Morales in his universe. But mimicking that plan worked out flawlessly, and he managed to see other universes as he pleased!

On the downside the machine exploded, opening a rip in the multiverse and taking Peter inside.

Now Peter is stuck in 7 different universes, and his only hope of getting out is from the help of others inside. But those people... or Some demons... aren't exactly what he'd expected.

Crossover between:
Miraculous Ladybug
Stranger Things
Harry Potter
Percy Jackson
How to train your dragon
Hazbin Hotel
Marvel

You obviously won't know all of these so I will explain all of what you need to know when needed!

WARNING: This started in 2019 and is still ongoing... I call this my sick fic. Every time I get bedridden and sick I continue to write this fic because there's something about a fever that makes me become an insane creative monster. I wrote a 30 page comic in 20 hours once while having a fever.
This being said, the writing is really bad but newer updates will probably get better.
REALLY SLOW UPDATES. Like... SOMETIMES OVER A YEAR BETWEEN UPDATES.
