I've heard of Gargoyles, which I believe was on early mornings back in my day (wow I sounded like a grandpa there!), which explains why I never saw it. Jackie Chan Adventures and Shaolin Showdown are shows I saw when I was young, and still remember them being good, so these are good choices.

I was honestly under the impression we were talking about western animated series, but I guess Anime is another option. Which unfortunately, I can't think of any that fit the Fantasy bill you're looking for.
