The only have one OCxCanon ship with Mamiko and Koko (Tarzan boy from the Zarude movie).
In my version of his story he goes through the events of his movie but he actually stays with the Zarude until he's in his teens and then joins up with pokemon rangers. Mamiko was working with her uncle for a similar organization and during a joint operation they met.
They didn't start dating right away but there was definitely chemistry from the start.
