arrow (season 5)
in may 2018, pedowitz and "arrow" lead stephen amell announced at the cw's upfront presentation that batwoman, fighting alongside the other arrowverse heroes, would be introduced in the upcoming crossover. the fictional gotham city would also appear. despite the inclusion of the character and city, the crossover would not include the television series "gotham" that airs on fox. that july, the cw was planning a potential standalone batwoman series after her appearance in the crossover; caroline dries, who was creating and writing the potential batwoman series, was expected to consult on the crossover. it was confirmed that "legends of tomorrow" would not feature in the crossover. "legends of tomorrow" co-showrunner phil klemmer said because the crossover was being used to launch the batwoman-led series, "it just became over capacity", and that because "legends of tomorrow" would have a 16-episode season, the crossover would have been "a tonal speed-bump, or a departure, and we just don't have time to step away from our story this year". despite not being part of the official crossover, "legends of tomorrow" co-showrunner keto shimizu revealed "legends of to-meow-meow", the show's episode airing the week of the crossover, would be "crossing over with ourselves" through the use of alternate time periods, and adam tsekhman guest stars as gary green in the "supergirl" episode.
