I own nothing of Pokémon and hopefully never will
Now keep in mind my spelling sucks and sentences suck and I haven't watched Pokémon in a while so if I spell anything wrong blame me and my terrible memory
This is basically a story about a weak charmander (hopefully I said/spelled it correctly) that's body is so weak it can't fight and having its trainer fight it's battles for it and the charmander has a timer and when they timer runs out it dies now the trainer being very attached to the charmander tried to make every minute count by having fun with it relaxing with it and just taking care of it now what the trainer didn't know was that this wasn't any regular charmander was the daughter of a very very powerful charmander and the charmander body is so weak that it can't use the power from its father/mother at all without making its body worse
now when the charmander died the trainer in determination decided to quit being a trainer and decided to take care of charmanders at the pokecenters now when the trainer died due to (made up disease here) he and the charmander went back in time except the charmander can turn human now it being the opposite of the trainer taking care of the Pokémon it's the Pokémon taking care of the trainer due to there relationship in the past they ending up dating
(This is as far as I got into this idea I'm sweating my AC doesn't work in this room have a great day ;-;)
