(Note: In “Crisis on Earth X (Part 1)”, the Tommy Merlyn here is technically a “new” character but is played by the same actor as the previous Tommy Merlyn. In addition, when he wears the Prometheus costume he is voiced by Michael Dorn who voices Prometheus in Arrow’s regular timeline. What I am is saying is that “legally” he is a Supergil character but I am deciding to count the crossover origin of all multiversal variants as whatever show their prime versions came from.
The appearance of Kate Kane in “Elseworlds (Part 3)” chronologically takes place during Batwoman season one despite the fact that the show had not premiered yet. At this point, her character premiered in The Flash portion of the Crisis on Earth-X crossover event. Outside of this unique circumstance, if a character only appears in a backdoor pilot or one episode, I am counting their “main” show as the only origin point. If they were previously recurring characters I will note both shows as origin points.)
The appearances of The Ray, Jason Todd, and Hawk during “Crisis on Infinite Earths (Part 1)” are stock footage.)

(Note: Supergirl appears via archive footage as a vision in the multiverse in the Flash episode “Welcome to Earth-2”.
In the Flash episode “Duet”, the character being portrayed is not technically Winn Schott but a musical fantasy character named Grady based on memories of Winn Schott. “Duet” is the second part of an story that began in the Supergirl episode “Star-Crossed”.
The versions of Winn Schott and John Corben appearing during “Crisis on Earth-X” are from an alternate universe.
Though technically introduced onscreen in the Flash episode “Elseworlds (Part 1)”, I will choose to define her as a Supergirl character because she was already mentioned several times throughout the course of the show.
Mar Novu appears via archive footage in the Arrow episode “Fadeout”)

(Note: There is a character in Freedom Fighters: The Ray who appears to be nearly identical to Dark Arrow called Black Arrow and was even said to be the same character by producer Mark Guggenheim, however because of convoluted timeline and continuity problems, they may be two different people.
The first onscreen character appearance of Elizabeth Tulloch as Lois Lane was technically on The Flash.
Superman & Lois initially took place in the same universe as Supergirl and the other Arrowverse shows. After planned crossovers with Supergirl and Batwoman fell through due to COVID-19, the producers decided to retcon it as it’s own separate universe.)
