We have a horse at home. Not that it's name is Epona....
But the original name sucks (we got her when she was already grown up), so I call the horse Epona anyway.
Well, sometimes. Usually I call her 'horse'. Just like our cats have no name, so I call them cat, or name them by color.
I only have the games and I'm fine with that. I like the ones I have in gold colored plastic, though.
Perhaps I would take a look at the manga comics, which could be fun. Alas, they don't sell them anywhere near (I think, I haven't actually looked for them).
