Avengers: Age of Ultron crossover.

Ultron’s plan had come to perfect fruition. There would be no more war, no more chaos, because the ones who caused it all would be gone. In just a short moment, the world would be saved from its true demon. Humans.

It would have all been so much simpler…if it wasn’t for them.

The Avengers.

As it is said, as it always will be, true peace can only be granted through countless innocent lives. In hindsight, the ponies were never that different from humans. Ultron’s plan is not yet over, and soon his strings will be severed…for the last time.

Big shoutout to Shrekzilla for his amazing job on the artwork!
Sequel: This War of Ours

It is recommended you read this story in one of the Dark formats in order to better distinguish the colored text of the 'other voices'.

Hey folks! Name's Deadpool!
I thought that was all of us?
It is. He's just introducing us as a single entity.
Will you two idiots be quiet? I'm trying to talk to the readers! Anyway, I know you've all been waiting with bated breath for this story ever since it was announced, and here it is! And it's going to have everything you'd expect of such a story!

Awkward hilarity.
Not to mention me, Deadpool, the merc with-

That's my girl! Hey, wanna read the story with me?

We should thank Sanyo21 for the image.

Yup!
Oh, and for those who don't know yet, this story is part of the PWNY-verse. It's not all about us - even if it should be - but you'll probably enjoy it to-Oh, stop making me a shill already!

Oh, by the way, it's recommended you read this story in Dark or Ultra Dark. Some of the colored text doesn't show up clearly otherwise. Not necessary, but just a suggestion.

Rainbow Dash has a freak accident while performing a Sonic Rainboom, and awakens to find herself in a strange new world, with strange new abilities.

Loki stands on the verge of conquest. His enemies are scattered; their greatest weapons are powerless to stop him. Very soon the Tesseract will open the doorway to an alien army bent on overrunning the planet. Everything has fallen perfectly into place for Loki to bring humanity to its knees.

But when a twist of fate radically alters the events which unite the Avengers, the impending battle for Earth is cast into a little world, an equine world. Now a group of remarkable yet dysfunctional individuals must learn from six colorful ponies that the greatest of teams are forged by the power of their friendships.
