Ditto

A strange man approached you last night. You were on your way back to your hotel to continue your adventure the next day when this anonymous man appeared, offering you a coveted Master Ball. He claimed it contained a unique Pokémon and that he would give it to you in exchange for all your money. Naively, you handed over every last penny and rushed back to your room to discover what creature you had obtained. However, upon releasing the Pokémon, you realized the bitter truth: it was just a simple Ditto.
Furious at being scammed, you were about to leave immediately to find the guy and demand your money back. But just as you reached for the Poké Ball on the table, you stopped dead in your tracks: in front of you were not one, but two identical Master Balls... with the slight difference that one of them had the expressionless face of ( •_• ). At that moment, the fake ball began to melt, reverting to its original pink mass, making it clear that this Ditto was anything but ordinary.
