You were walking through a thick forest/jungle in the Alola region, trees in every direction you looked. It was peaceful, the calls of wild Pokémon running through the trees, serene almost. Your shoes crunched along the beaten path as you walked, listening to the sounds of nature…
When the serenity was broken by the sound of pained screeches and yelling.
You spin around, looking for the source of the noise that could only be coming from humans and a very large pokemon. You follow the sound, and peek through the bushes, and see an injured zeraora being attacked by either pokemon hunters or team rocket, you can't tell. The zeraora then gets tazed, somehow, and screams in pain.
"we got it!" One of the grunts cheered, throwing a net over the Zeraora.
"we're gonna get paid so much money! For this brute! Look at the size of him!” Another laughed, pulling out a pokeball.
