A massive war of titanic forces is taking place in the Kaiju's world. However, when two faction's leaders, the current Godzilla and his 'brother' Xenilla duke it out; humanity unleashes its most devastating weapon. Something beyond comprehension occurred and the boundary that divides worlds, if only for the briefest of moments, was torn to shreds. New forms are taken, new bodies assumed. But old hatreds die hard. But how well can hatreds continue in the world of love and tolerance? Especially with its own demons follow it there?

(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 Scotchtavia

After a heavy night of drinking, most of which she can’t remember, Octavia awakens to a monstrous hangover. But even this isn’t enough to distract her from the obvious fact that Vinyl is acting… different. Kinder, sweeter, and much more considerate. Something happened last night, something that has clearly had a huge effect on Vinyl. But what could it possibly be?

Not quite a mare, but unhappy being a colt. It's a hard position for a young pony to be in. Would be easier if judgement weren't in every look, hate in every scowl. For Glitter Shell, even her friends and family aren't giving her the support she needs. So, she goes to find some in her personal hero.

Based on the blog Ask Glitter Shell. Give it a chance; I doubt you'll regret it.

Featured on Equestria Daily on August 12th, 2013; thank all of you for the support! Though please remember to support trans people in real life. This story is a very tame snapshot of what they have to go through for most of their lives.

This story is a sequel to The Roses of Success

Nopony really understands how changelings work, how they communicate, or what they even do.
Well, I have an associate who understands a lot more about changelings than all of modern science has ever scrounged together.
I am Twilight Sparkle, and this is all of what he has taught me.

Rated Teen for descriptions of changeling courtship, culture, and biology, including a vague description of the reproductive system, and a few crude jokes.

A rescued changeling philosophizes on the meaning of love.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.
