As the patron saint of tongue-in-cheek humour and playing with comic tropes, it was practically written in the stars that Deadpool would end up having some saucy selves in alternate universes.
He's the one character who could justifiably do or be just about anything, and so long as his wit was sharp and his references were pop, you'd still recognise him as the Merc With a Mouth from a mile away.
This has only been helped with the Deadpool Kills Deadpool series, which saw light shed on the multiverse of Pools and their respective appearances and personalities. Although this does mean we have a grim awareness of many of their fates - as a ton die in said series - it's still well worth it to see just how creative and how weird the writers and artists were allowed to get.
The multiverse has never been so perfectly used as when it's letting us witness things like a Hello Kitty version of Deadpool, as the meta nature of Wade Wilson works perfectly into a cast of weird, wild, and wonderful characters - and some zombies.
