Anime

So you have chosen to be from the anime timeline. This will be interesting. This eliminates some of your autonomy as some events NEED to occur to keep that timeline running smoothly. In short it only changes what YOU would do in these situations, not if they would happen or not.

Regardless you are still given the choice to be a human or pokemon in this timeline. Perhaps  you take the place of Ash or Misty, or their gender swapped versions. Or perhaps you take the place of a pokemon, be it the iconic pikachu, the charmander that was left on a tock, the Chimchar rescued from the asshole Paul, or even the newest asset added Riolu.
