If for some reason Yoshi P decides to follow the FF6 route of ninja, I guess it could be a pet class? Though Interceptor only came out every once in a while, and it didn't really have to do with his job at all, more of a story thing, seeing that if you didn't get Shadow back, Relm would have control over him..... But if Yoshi P did follow the FF6 guide to ninja, it would mean we would be allowed to chuck a bunch of weapons at monsters and do massive amounts of damage... which would be awesome! (but 99% sure that isn't going to happen)
