In this kind of fanfiction, it would be a really interesting twist. Ash usually starts with Pikachu, but having Gengar as a starter would change a lot of the story dynamics. Gengar is a Ghost/Poison type, which is much different from Pikachu's Electric type. This could lead to different battle strategies and interactions with other trainers. For example, Gengar's ability to phase through walls and its spooky nature could add a whole new element to Ash's journey. Maybe he would face more challenges against trainers who are used to dealing with the typical starter Pokémon types like Fire, Water, and Grass.
