Yaaaaaaas. Need to think of character concepts but some Personas that immediately come to mind could be Gilgamesh, Koschei the Deathless, Nicolas Flamel, Count of St. Germain, Cartaphilus, Galahad, Merlin, Sun Wukong, etc. Some of those are admittedly better than others because a couple of them didn't really [i]seek [/i]their immortality quite as purposefully as others, but they're all ideas.
