"It is time."
"Time for what, M. A. Larson?"
"You shall see soon, my child."
"What do you mean?"
"Here, take this pair of wings and horn. Now, where's that button?"
"What butto--"
A single beam of golden light descended from above, unceremoniously horking out a large, gelatinous blob of slime. And no, it is not the Smooze.
Inside this blob, was an Alicorn.
Though, not just any Alicorn, for this Alicorn was the Alicorn of Alicorns. (And repetition, because why else would Alicorn be used four times in the previous sentence?"
Why did this Alicorn exist? Why, to ascend everypony, Alicorns included, into Alicorns, of course! Why else would M. A. Larson do such a thing?
Celestia? Alicorn.
Apple Bloom? Alicorn.
Big Mac? Certainly an Alicorn.
Trixie? Nah. Let her ascend herself. Let's make Starlight Glimmer an Alicorn instead!
Discord and the Twilicane are Alicorns, as well!
Even Boulder is an Alicorn!
Fluttershy worriedly stared at the Alicorn Angel Bunny.
