You were an amazing Pokémon trainer. You were second best, and were about to go into the gym to fight the last person, and officially become the best trainer. However, while you were travelling through some tall grass, you ran into a Pokémon. When you looked to see what it was, you saw it was a Shiny Sylveon. It looks up at you curiously, it's head tilted. You fed it a big berry to make it trust you more, than managed to catch it using a master ball. You looked at the stats, it was a male, quite tall, and quite light in weight, it had a lot of health, attack damage, defense, et cetera. You took him out to train him, and to raise his stats, and he seemed to gladly take out the other Pokémon, and came back to you, with a smile on his face.
