In Equestria, everypony views heroes as stories for fillies and not to be taken seriously. However, in another reality, heroes do exist. When a dimensional transport portal goes awry, a certain vigilante finds himself in a colorful land full of ponies. And he isn't happy. Will Batman have to fight his way out of Equestria? Or can even the most dark hearts find peace?

Batman will be based off the arkham city batman universe with a few villians thrown in.
other heroes will be mentioned or have a minor role.

I OWN NOTHING.

Please comment and/or critque

An undead Emperor in need of a new body. A Spartan lost in space. A ragtag team on a suicide mission. What do they all have in common? They all wind up on the magical world of Equestria, where war has been forgotten. That, however, is soon about to change.
When each of them is about to be retrieved, ancient evils arise to unleash hell upon the unsuspecting world. When the forces of three galaxies clash around them, can our favorite ponies hold out against the onslaught?
This is a crossover involving Warhammer 40k, Halo, Mass Effect and MLP, and is also my first fanfic. Comments and reviews are welcome.
Rated T for language, violence, and general adult situations.
Now on Tv Tropes!

While pursuing a splinter of Hive Fleet Behemoth, Captain Sicarius and the Ultramarines 2nd company are caught in a warp storm that carries them and their prey to an unknown planet. Meanwhile, Princess Luna notices something strange in space that could spell danger for all of Equestria. Swept up in a war between the terrifying Tyranid swarm and the vengeful Ultramarines, the ponies must fight for their lives in a war that spans a galaxy.

Thanks to thirdstring_overlord and GiftedMonster for proofreading my newer chapters. thirdstring_overlord also writes an excellent 40k crossover that needs some fans. Go check it out!

After the War of the Ring and the return of peace to Middle-earth, Gandalf the White departs for Equestria to visit two old friends of his; specifically, a certain pair of alicorn sisters.

Yet he does not foresee that Equestria, like ponykind, has changed with the years since his previous visit, and so he is quite unprepared for what lies ahead. Can the Wizard endure the trials that this new journey will bring? Surely, but only if he makes a few more friends along the way.

Six more, to be exact.
