The main character of my Wolf's Series on AGNPH (check my journal for the link), Wolf O'kai is a pokemon trainer in his early twenties from Fortree City in Hoenn who fell in love with his first pokemon Lucky the Lucario soon after she confessed her own feelings for him.

Wolf is a laidback person, content to deal with events as they unfold around him. He started his trainer career at the age of seventeen after several strange occurrences (alarm settings, Mightyena being attracted by raw meat in his backpack and the unexplainable presence of a Magnemite that caused all of his alarms to malfunction, etc) prevented him from getting his first pokemon for seven years until he met Lucky and her parents.

Wolf and Lucky began their relationship in the fourth year of their partnership, Lucky telling him that she was in love with him one night in Eterna City. Soon after Wolf found that while Lucky was his girlfriend, she was willing to allow him to be open about it with other girls. He has even been able to have a child with both Lucky and Serenity the Gardevoir, the latter only occuring due to Lucky's expressed permission because he respects her feelings in the matter of less casual sex.
