While lounging around Twilight's castle and airing some friendship-related grievances, Discord stumbles across a magic book containing letters from an inter-dimensional pen pal. As it just so happens, this pen pal also had sinister designs for Equestria, but was quashed by the Elements of Harmony. What's more, she's made amends since that day, and she's now Twilight's friendship student. Eager to bond with someone who can relate to him on a personal level and grow into a better draconequus, Discord packs his bags and heads off to the human world with Twilight's semi-blessing. His mission: Befriend Sunset Shimmer.

However, his plan has a bit of a snag. See, Sunset hasn't been keeping up with Equestrian events, and she never got the memo about Discord turning over a new leaf. As such, she believes that his sudden appearance doesn't bode well for Equestria, Canterlot High, or herself. Not only this, but the Sirens are privy to Discord's return as well, and they see this as a golden opportunity to bounce back from their own recent defeat. Well, Adagio does, anyway. Sonata doesn't want to live in a world that makes no sense, and Aria would rather maintain what little dignity she has left by not getting involved (or so she claims).

So while Discord is trying to earn Sunset's trust and show her what a good friend he is now, Adagio is trying to get in on an evil scheme that doesn't exist. And while that is going on, Sonata is appealing to the Rainbooms behind Adagio's back, hoping that they'll make Discord go away. With so much miscommunication thrown into the mix, you just know that hijinks are inevitable. Good thing Aria made popcorn.

(for any G-fans, Xenilla is the kaiju you may know as Spacegodzilla. I changed the name because I got quirked about typing it repeatedly and am writing the story so it can at least be understood by just an MLP or just a G-fan; and thought it get very confusing that one character's name was just another character's name with an adjective. Also... don't pretend it's the most imaginative name Toho has every made)

This story is a sequel to Oskar Osäker: True Omnivore

Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

Not all of Alex Mercer's "Evolved" were loyal psychopaths. Some were simply desperate people who Alex thought he could easilly control once he infected them with the "Mercer Virus". However Alex was never one for fool proof plans as he quickly finds out when only a handful of his Evolved army show up at that fateful final battle between him and Heller. Oskar was one of the many of dozens of Evolved that stood by and watched as Alex was consumed and now he finds himself in a strange cutesy land filled with talking ponies. Can this viral being find peace in Equestria or will his need to be secure get in the way?
