How about Koschei the Deathless ? He seems sort of neat. He sort of reminds me of Zouken, what with the whole "Shriveled up old man who is hard to kill" thing. Apparently he has a legendary horse of some sort, so I suppose he could be a rider, though my initial opinion would be that he fits more as a caster.
