Friendship is Failure idea (The Invisible Pony)

It's an idea I've been wanting to try for a while, it may be a long movie like some of my FIFs

THE INVISIBLE PONY (Not like the Invisible man)

Concept is simple...

Many years ago there lived a great pony wizard and his apprentice (An orphaned pony) Then, one day, while mixing special potions, the wizard's place caught fire and burned to the ground, and worse the unstable potion poured onto the apprentice which rendered him totally invisible.

The apprentice only reappears in the light of the full moon, but once the sun rises again, he vanishes once more, and it's far worse.

Each and every year, he fades more and more into the air around him. His voice becomes fainter and his footsteps get light. Unless he can undo this curse, he himself will eventually disappear into complete and total nothingness, never to appear again (A fate worse than death... Non-existence)

Unfortunately, he doesn't know what kind of magic this curse is, as it was created by accident.

His master is dead, and the place is burned down with all the notes, research and resources, it's all gone.

He has no answers whatsoever.

He does, however know of ONE thing for sure that will cure him.

His master once had a secret laboratory far from his home, where he once created a special potion that can cause instant healing to even the most fatal of injuries and curses.

...But he has no idea where it is (His master never told him) and with no notes or maps-- all the secrets dead with the master and the home.

He went on a world wide journey over all of Equestria for years and years hoping to find this lab, get the potion, and cure himself before his disappears forever.

Due to his invisibility, he can sneak around pretty well, and often uses it to his advantage to make jerks and scoundrels suffer.

-Pours a bucket of water over someone's head
-Trips them up with his limb while they are running (and they never see it)
-He overhears nasty plans and writes letters to the would-be-victims warning them in advance.


Twilight and friends eventually discover him, and try to help, but unfortunately even Twilight's best knowledge, and greatest spells have no affect.

The hidden potion is the only hope.

Eventually, they stumble upon the wizard's old lair and discover there is a magical potion... with just enough power to cure ONE, and only ONE. (A potion this powerful and extremely complicated to conjure is not kept in good stock)

Twilight's is unable to analyze the ingredients as she has never seen such things, and even if she can, they are extremely rare, and or extinct, and even if by some miracle the ingredients are found, this potions takes a long, long time to effectively make (Much like how the Harry Potter Polyjuice potion needs a month to set) So mixing up a new potion at this point is completely impossible.

They are ambushed by enemies (Still have to work that out) but they also seek the potion hoping to sell it and get rich off of it, (Or maybe something else) and a big fight ensues.

In the end, I want it so that in the midst of it all, Shining Armor is mortally wounded, poisoned or something along there, and is dying. His only hope is the potion.

The apprentice can't bear it.

"Here, Shining Armor... you need this far more than I do.

...this is the way it's got to be."

So Shining Armor is cured...

the Sun rises and the pony vanishes again... REALLY gone (Body, soul... everything. He's never even in any spirit world. He's GONE!) as any clothes he had on to appear visible just flop to the ground.

Friendship just didn't cut it this time because they are not able to save him.

I think it could work out.
