Just here thinking about Steve getting isekai'ed. Like. One of my favorite things is reading generic isekai mangas/manhwas with overpowered protagonists and convenient situations at the point i don't even remeber wich ones i've read.
So imagine one Steve harrington getting summoned into an isekai, him being the basic hero who needs to defeat the demon King, going on a journey, making comrades, learning magic and using a sword, etc, etc.
But also, him having already lived the upside down. Steve being summon shortly after the events of the fourth season (just without eddie dying), with the experience of fighting monsters, the survival mode still in his system, with the fear that the monsters of this other world could came to his own through glowing magic circles just like he did.
Because of that, after the princess and the saint had promised him that he could go back to his own world, to his home, his friends (his family), at the shortest time possible after he got summon, didn't matter how much time he spend in this other world. He decides— like the self-sacrifice idiot with a hero complex that he is— that he would help.
Clue Steve living a whole isekai for almost a decade just to come back after a week had passed in his original world.
Of course The Party would have noticed Steve's missing, the Gates are still open, the whole town split apart, monsters hadn't started to appear but is only time until they do, so of course they are high alert and notice when one of them just go radio silent.
Nobody knows where he is, what happened to him, if he's still alive. And since the whole town is a mess they can't exactly do a search for a misssing person.
And just like he disappeared, he reappears one week later, Hopper founding him drinking beer in the only still open bar of town with more scars than before, carrying a sword in his waist and with all the powers and cofidence he gained in the magical world intact.
Now if Vecna decides to make his come back, he would stand no chance against the rage of a superpowered teenage girl, a rag tag group of teenagers, four tired adults and a returned hero with almost a decade of experience fighting beings more powerful than he.
