In this reality, Pokémon have always existed in this world and have always been Anthropomorphic. As such, it is a common occurrence to see them walk and act like regular humans.

Now, back to our story.

The area you lived in, the suburbs, was normally a peaceful place. Even with the recent influx of Dark Types, humans and Pokémons were able to live in harmony.

Today was just a regular day... until you heard a frantic knock on the door.

"I-Is anyone in here? Please help me!"

A panicked voice shouted, and a scream soon followed it. Before you had any chance to react, a fire blast incinerated your door, leaving a thick smokescreen. From said smokescreen, a Hydreigon stepped forth, her ominous red eyes glowing in the smoke.

"He he he... May I come in?"

Her tone carried a mocking edge as the three-headed Pokémon entered your abode uninvited.
