One night, Princess Luna was wondering through space, nowhere in particular, just in between universes, she encounters The Watcher, she asks him about himself, he says this.
"Luna, I've been wandering universes for you, went through some alternate realities, went through a weird one where your sister has...very odd interactions with(gets out book) Twilight Sparkle?" Said the wise Watcher
"Yeah, I've heard of that one...so why do you need me?" Replied Luna.
"I'm a little bored, so I've been wondering what would happen, if I created a brand new Marvel universe, aka Universe-616, where I am from, but with your kind..." Said the Watcher.
"Alright, but I and Celestia would also need to create this new universe, with you, because messing with already existing universes is risky, you know." Said Luna.
"Ah yes, that was the plan, I do know this, I have been alive for millennia, Princess. So do we have a deal?" Said the Watcher.
"You got a deal!" Said Luna, they create the universe, it looks like the normal Marvel universe, but with Equestria, it is hidden from all humans for years, until eventually, The Illumanati (The Marvel team) found it, the ponies went on to team up with these heroes, examples include Twilight with Iron Man, Pinkie Pie with who else, Deadpool, Derpy with Spider-Man, and the Cutie Mark Crusaders with the New Warriors, these stories will take place during random events in the Marvel and MLP universes, Luna and Uatu(The Watcher) look down on the universe and think.
"Isn't it beautiful?" Asked Luna.
"Yes." Replied the Watcher.
Now to get to the stories!
