Ce Acatl was a Native American Human who was a direct ancestor of Starfleet officer and Maquis leader Chakotay.

While on a vision quest in 2372, Chakotay spoke to his deceased father Kolopak for advice about his supposed child with Seska, who had evidently impregnated herself with Chakotay's DNA. Kolopak spoke to Chakotay about one of his ancestors, Ce Acatl, who was the child of an Indian and one of the "white conquerors" who raped Native Americans on Earth centuries before.
