OC/SI as a Trainer's Pokemon fics?

Anyone knows fics of an OC or SI as a trainer's pokemon? I've read a few from a Zubat that runs into and sticks with Paul, or a Tyrunt with Dawn, and a Magikarp with one of Misty's sisters, but it's hard to find more than that. Doesn't help that I stick to Ao3 mostly, so I don't know if there's more that I haven't seen on other sites.
