T'Kuvma
A messiah was a title for an individual who had, or was believed to have, the power to save a people, group, or members of a religion from some calamity.
In 2256, Michael Burnham compared T'Kuvma's role in the Klingon war to that of a messiah. (DIS: "Battle at the Binary Stars")
In 2373, Q proposed that he and Kathryn Janeway have a child together, saying the Q Continuum needed a new messiah. (VOY: "The Q and the Grey")
In 2377, after learning that his daughter could be the prophesied kuvah'magh, Tom Paris remarked to B'Elanna Torres, "I was hoping our daughter would be special, but I never dreamed she'd turn out to be the Klingon messiah." Torres didn't appreciate his comments, fearing the child's life might be in danger. (VOY: "Prophecy")
In the final revised draft of the script for "The Conscience of the King", Kodos (according to Kirk) appointed himself as a Messiah before flipping the switch that killed the four thousand Tarsus IV colonists.
In a deleted scene from the Star Trek: The Next Generation sixth season episode "Rightful Heir", Geordi La Forge describes the clone of Kahless as a Messiah. [1]
