Tom Cavanagh. First appearing the sixth season of The Flash, Nash Wells is a multiversal traveler whose objective is to find and kill Mar Novu / The Monitor, believing him to be a false god. During his travels, Nash travels to Earth-1, in which he finds a gate beneath Central City. After accidentally opening it, he frees Novu's evil counterpart, the Anti-Monitor, from his confinement. During the events of the crossover "Crisis on Infinite Earths", Nash became a "Pariah" for releasing the Anti-Monitor and is forced to bear witness to the destruction of the multiverse. As the Anti-Monitor destroys Earth-1, Nash sends the recruited Paragons to the Vanishing Point under Novu's orders. Following the Anti-Monitor's defeat, Nash is restored to his original self and temporarily lacked his memories as Pariah until the Martian Manhunter restored them to remind him of what he did.
