Author's Note: "Assassins & Pokémon" is a crossover story of "Assassination Classroom x Pokémon" in which it features everything from all eight generations. This is the first crossover fanfiction for "Pokémon's 25th Anniversary," with "Assassination Classroom" touch.

I don't own any of the stuff in this story. This is the first crossover story of both universes "Assassination Classroom" and "Pokémon." Summary will be introduced on the next two stories after this. Thank you.


"Assassins & Pokémon"

Chapter 01: Introduction (narrated by Koro-sensei)

Welcome to the crossover story of "Pokémon x Assassination Classroom." My name is Koro-sensei, and I'm a Pokémon Researcher.

For as long as humans and Pokémon have lived on this planet, there has been the presence of these creatures. Some believe that their existence predates even that of humans. Perhaps it was the Pokémon themselves who created the world we live in today. Together, humans and Pokémon have lived, almost as if one cannot exist without the other.

Some humans use Pokémon in many different ways. Some simply keep them as pets or for entertainment. Some use them to protect other humans and Pokémon against those who choose Pokémon to cause chaos around the world. Some learn about the secret of "Mega Evolution," a new technique in which remains hidden in mystery. Others use a variety of techniques like Z-Moves and so much more to be revealed.

The most popular use for Pokémon is training them for battle. Adults and children alike around the world go on to become the strongest of trainers and compete in professional battles. Those who prove to be the strongest go on to become champions of various regions around the world. Those who do may participate in activities like contests with such splendor and a lot of talent.

You came at a most interesting time. As we speak, word is spreading quickly of the Kunu region looking for its next Pokémon Champion.

Welcome to the world of Pokémon.


Author's Note: Since Koro-sensei's death in episode 46 of Assassination Classroom, I'll make this crossover story an AU of these two series merged into one story. Koro-sensei became the narrative voice of this entire story. Up next will be a main character for their next story, so stay tuned. I'll rate this fanfiction "K+" for mild cartoon violence, mild humor, and even mild language to keep it PG and family-friendly.
