I mean the character inspired an entire genre if I'm not mistaken that's beyond impressive beyond his cameo in the Spiderverse events it's sad he has not made any major appearances. This is why I think it'd be cool to get a Spiderman event where the two team up like Peter learns of a new Spiderman in Japan claiming to be the original and goes over to investigate. Then has to team up all the while Japanese Spiderman acts as the bad cop to his good cop for the twist maybe it comes out the spiderverse events or something else merged their two time lines causing them to exist in the same world.
I also like the idea of the Iron Cross Army getting revamped as a serious threat and Professor Monster being revamped as a Mr. Sinister style villain. Also it'd be cool if he kidnapped some of Peter's rogues and modified them making them more dangerous and sending them out as his own Sinister Six. Lke maybe modifying Shocker so he no longer needs his suit and is made into a more serious threat. There are just so many things that could be done and I love the kind of interactions the two heroes could have.
