An Important Delivery

"Fearow, it is absolutely vital you deliver this package, okay? I'm counting on you!"

Fearow saluted, determines to make its Trainer proud.

The trip was long and arduous, taking many days, but Fearow would not give up.

It braved storms of lightning and snow, pressing forward despite singed feathers and chattering beak.

It flew over the ocean, rarely stealing rest on passing ships.

It flew over the jungle, where it fought off Wild Pokémon that tried to steal its cargo.

It flew higher than it thought possible, straining its wings to fly over a mountain.

A red mailbox sat innocuously at the top. Exhausted and bruised, Fearow dragged itself to the box, reaching for the little door with its beak.

It had been through Hell and still needed to go back, but finally it had achieved its goal. Finally it would make its Trainer proud! Finally it could go back home–

Fearow squawked and flapped backwards in fright as a cloud of glitter exploded from the open mailbox, covering it in pink and green. A small note fluttered gently to the ground.

[HAHA! GOT YOU, FEAROW :D]

Fearow tore into the package. It was empty. Its journey had been for nothing. Its struggles had been for nothing. Merely a cheap laugh for its Trainer.

On that day, Fearow became embittered, exhaustion and pain and betrayal clogging its mind, sealing off its heart. It never returned home, instead taking over the mountain, viciously attacking any human that dared enter its new territory.

Other Pokémon that had been betrayed or abused heard of its fearsome reputation, flocking to it for protection and solidarity. Their influence grew, until the island the mountain sat in became entirely unsafe for humankind.

On that day, Fearow finally had its revenge.

Let this be a lesson to us all. Pranks can be fun, but they must never be taken too far. Some things just aren't funny.
