At her brother shining armor wedding Twilight is turned into a changeling by Chrysalis.

A brony from earth is thrust into Equestria, but as a changeling.

The world created by Rust and expanded by Blackwing, but with a more feline view.

Went to a Comicon dressed as Basco from Gokaiger, mixed in a few other things like a suitcase full of my Bakugan collection, met the rumored Merchant and wound up in a mix of Equestria Girls, and Anthro Equestria.

Twilight, Fluttershy, and Pinkie pie are teleported to the north when they are cast out of the wedding.
