When a visitor comes to Ponyville, Fluttershy finds herself attached to him. And of course, the visitor, Silver Storm, likes her back. But there's just one thing about him...

A unfinished experiment has escaped from a lab, and is on the loose. Everypony is supposed to be on the lookout. They have been warned that this experiment is dangerous and highly toxic.

Meanwhile, a filly finds herself in Ponyville, and is suffering from amnesia. The only thing that could be a key to her past is a black toxic symbol on her hoof, and she doesn't even know what it means!

Soon, the filly finds herself under the care of Pinkie Pie and her friends, and named Sugar Fluff, at least, until they find her parents. But who is this filly, and where did she come from?

When Princess Celestia tries to realase Twilight Sparkle's magic calmly, she messes up. Instead, she unleashes more than she wished for, turning Twilight into a alicorn with one goal: to rule Equestria as a queen.

Now her friends must try to stop her evil self. Will the friends be able to stop Twilight? Or will Twilight rule Equestria as a queen forever?

(I was inspired to make this fanfic by this http://esuka.deviantart.com/art/A-Mentor-s-Helping-Hand-256281760 , but with a different storyline.)

Discord has escaped once again, and Twilight goes to confront him. But when she does, Discord sends Twilight back in time, to when she learned of Nightmare Moon's return. Now, Twilight must try to stop Nightmare Moon once again and stop Discord. But it seems impossible when Equestria is already in chaos.
