A long time ago, a whole manor, and everypony inside it, mysteriously disappeared without leaving any trace.

But it reappeared at the edge of the Everfree Forest, and Twilight decided to go investigate followed by her friends, only to not come back. Worried, and not wanting to miss an occasion to get their Cutie Masks, the Cutie Mark Crusaders entered the manor at the start of the night, only for two of them to be foalnapped by ghosts, and for the third to barely escape with the help of an old stallion.

Now armed with the Poltergust, a powerful tool to capture ghosts, Apple Bloom returns in the manor, ready to save everypony, even if she has to fight every ghosts in this manor.

A long night of terror starts for her.

Happens between season 2 and season 3. Also possesses some Dark and Drama

The saga now has a TV Tropes page (spoiler for the whole saga).

After a good day passed crusading, Scootaloo is napping before returning to her home when a rift suddenly opens before her. Out of the rift comes a strange ruby followed by a bipedal mustachioed being. Scootaloo quickly discovers that the ruby possesses great powers but before she knows it, she accidentally merges with it.

Now, she has to learn to control her new phenomenal powers, fight the mustachioed being who reveals to be a mad scientist who wants to use the power of the ruby to return home (and conquer Equestria on the way), and deal with the spirit of a sicko trapped in the ruby calling himself Infinite.

Perfect setting for the rising of a new, awesome super hero: Zero.

Crossover with Sonic the Hedgehog. Starts during season 4 of My Little Pony and after the events of Sonic Mania Plus.

Almost one year passed since this famous night where Apple Bloom had to face a whole manor full of ghosts to save her sister and her friends. Now a professional ghost hunter, helped by her mentor professor Smart Spirit, she regularly hunts bad ghosts all over Equestria.

But one day, she learns from Diamond Cup, who went with Smart Spirit to do some research in a mysterious haunted valley named the Evershade Valley, that the ghosts of the valley, usually pacific, have suddenly turned hostile and captured the prof!

It's now up to Apple Bloom to find the origin of this hostility and to save Smart Spirit, and the valley, but she has no idea who she's up against this time.

Several months passed since Sweetie Belle fought Kirby and became the Alicorn of the Void. The filly is thirsty for new adventures, discovering new universes, making new friends, fighting new bad guys. Feeling that she is ready, she opens a portal, and starts her new life.

Not knowing that many universes will rapidly be threatened by a mysterious army, and that she will have to fight Light and Darkness to save everything she cares.

This is a rewrite of the A Mega Blast from the Past series.

Twilight Sparkle, now the new high Princess of Equestria, has been having a meeting of the Council of Friendship. But since then, things haven't been quite alright. Since Twilight has moved into Canterlot Castle, Nyx (from Past Sins) and Joshua (from New Life in Equestria) have been having a tough time since they transferred from the Ponyville Schoolhouse to a school in Canterlot. But things have been getting a bit complicated when an unknown magical force surrounded all of Equestria and beyond it's border, sending all of the creatures there so an entirely different place, transforming all of them (Except for Joshua) into humanoid versions of their original bodies.

Things might get a bit complicated when one of that world's governments attempt to take over Equestria as part of their own custody, but the only way for them is to get the help of the creatures similar to what they have become, some of which in a group called the Freedom Fighters, being led by the legendary hedgehog, Sonic the Hedgehog.

The battle against evil. A never ending cause that spans across infinite universe. Despite how different each and every reality may be, there is one constant. Good vs Evil.

But what happens when the evil forces of two separate worlds come together? Can one world's heroes handle another world's villains? The Elements of Harmony can handle any magical foe, but what will they do when their foe sends legions of mechanical monsters against them? And while the Freedom Fighters can smash through any machine, can they stand against the darkest of spells and darkest of souls? Can the heroes, who have such different tactics and stories, overcome their differences to take on the task at hand?

But above all else...is there enough room in this crossover to fit both Rainbow Dash and Sonic's egos? I hope so.
