Everyone has their own way of deciding when a Pokémon evolves in their story. I haven't used evolution much in anything I've posted anywhere, but that's why I'm asking around! In a side story I'm writing for Pokémon Resonance, the Shinx belonging to Jack Powers had been in bad shape, thanks to a Mega Pidgeot used by Fawkner. I had the Shinx in question, Atlas, evolved while battling a wild Growlithe because he was Jack's only Pokémon and the fact that he was still recovering from the beating he got from the Mega Pidgeot he faced before, so naturally I had him close to evolving. How does everyone else decide when a Pokémon in their story evolves?
