Twilight Sparkle never thought she'd see the day: the day that her mentor, Princess Celestia, would fall to the dark side...but now it's here. Now, she must call upon allies both from her reality and that of another to fight under the banner of the only pony who up until now had been able to challenge her: Princess Luna herself. It's about the only way she'd be able to help her now...

Takes place before Season 7; inspired by "Injustice: Gods Among Us"

The Green Goliath has, against all odds, found his way to a strange land of ponies: will he become their best friend, or their greatest enemy?

*previously called "Crisis on Two Equestrias"* inspired by "Justice League: Crisis on Two Earths" They have defeated the greatest of foes, overcome countless obstacles, but now the Mane 6 face their greatest test to date: can the Elements of Harmony help dispel a darkness when they ARE the darkness? *currently being reworked*

They are their respective world's greatest heroes, but when brought together against common enemies, will they be able to save the day?

Takes place during Arkham Origins (warning: possible spoilers) When "Black Mask" hired the assassins, it seems that he had a little assistance in contacting them, among other things; can 6 ponies from a magical land help the Dark Knight face this new threat to Gotham?
