Imagine William loves Pokemon and insists on taking the kids for walks frequently so they can play Pokemon Go together, there is a gym just down the road from their house and they almost always have control of it.
William mostly uses steel type Pokemon and his shiny Aggron is his strongest Pokemon, he knows it’s not much use DPS wise but he loves it none the less.
Michael likes a variety of Pokemon, his strongest and most used is his Gyrados, Gengar is his favourite Pokemon.
Elizabeth loves the cute fairy/baby pokemon, her favourite and most powerful is her Celfairy which she named Ballora.
CC loves collecting Teddiursa and any Teddiursa the others catch they trade to him, he has a few baby Pokemon he loves too but has over 200 Teddiursas with about 30 Ursaring.
