When Twilight tries a mass teleportation spell with her friends they get stuck in another universe. What's worse is that their landing point was a magical spring that curses it's victims to transform into whatever drowned there. They are now cursed to turn into human girls whenever splashed with cold water, but hot water changes them back.

They weren't the only ones to fall in that day. They meet Ranma a male traveling martial artist who fell into the same spring (meaning he turns in a girl), his father Genma who becomes a Panda. Twilight agrees to cure them when she figures out a cure while they give her and her friends a place to stay.

Due to a series of events, they wind up in Japan where they must pose as normal high school girls. Where they must deal with a stupid swordsman who falls in love with them, martial arts based on running, rhythmic gymnastics and figure skating, rivals from those sports. And that's barely scratching the surface of the insanity that lies for them...

During the battle with the changelings, a trapped Discord manages an undirected spell that reaches across universes to bring an agent of chaos to Equestria. What's brought back more than qualifies.

Steam! Gears! SCIENCE! A very confused Spark! And, eventually, really good coffee.

Here comes Agatha Heterodyne--MARE GENIUS!

Chrysalis is dying, and with her, the last of the Changeling race... but there might be a way to avoid extinction.

It's been three years since Princess Luna, the Nightwatcher has been returned to her throne and three years since Twilight Sparkle and the virtuous six have parted ways and gone back to their separate lives. But after a few years of peace, there are reports of a series of murders and break ins on the outskirts of the major cities of Mystika. As Twilight Sparkle investigates, she uncovers rumors that the Shadow Blade cult who did the bidding of The Nightmare back during the Dark Times, are back in force. And they have a plan.

Brought to you by Loyal2Luna, this new Downloadable Content for Mass Effect 2 brings the fight to Equestria.

Just about ready to embark on their mission to stop the Collectors from further abducting human colonies, Commander Shepard and the crew of the Normandy SR-2 are given a new priority, when the Illusive Man tasks them with investigating the mysterious disappearance of a Cerberus science team.

Soon, what begins as a simple search-and-rescue unveils a mystery millions of years in the making, and the Commander finds himself thrust into a situation he couldn't possibly have prepared himself for.

Join the Hero of the Citadel as he uncovers the secrets, combats the demons, and ultimately decides the fate of the impossible world known as "Equestria."

(Post-Mass Effect 3)(FemShep)
When the Reapers were defeated, the galaxy believed that Shepard and Anderson were both lost in the final battle. However, the two long-time friends were also known for not letting death stand in their way.

Waking up, in the middle of a desert, on an uncharted planet they both embark on their strangest mission yet. Attempting to find their way back to the Human Alliance, a place called Canterlot may hold the answers they seek. But first, they had to get there while trying not to draw too much attention to themselves.

Too bad for Anderson since massive explosions and collateral damage followed Shepard wherever she went, without fail.

Crossover of My Little Pony and Mass Effect.
