Hoo-wah! Lil’ bit of a late reply here, but man, it takes me a while to get back to these questions. Kinda get buried.
You’re in so much luck, sweet’ums! Because there’s not only one, but two series coming this fall with Deadpool and Spider-man working together! Of course, I don’t really count them because it’s ridiculous billionaire Spider-mobile driving Peter Parker (aka Batman), rather than the Peter Parker we know and love, but it’s still promised to be an absolute heap of spideypool trash. We’ve got the new Uncanny Avengers series coming soon, where they’re both on the roster, and also a Spider-man and Deadpool team-up series, as of yet unnamed. Not sure if it’ll be ongoing or not.
As for what we’ve already got, which actually isn’t very much, here’s a few of my favourites, and the ones that you just can’t miss. I’ll try to keep it as brief as I can, but I do like to be thorough.
