Legends of Tomorrow showrunner Phil Klemmer says he's happy to sit out this year's big Arrowverse crossover, since the show's fourth season only has 16 episodes to work with. This year's crossover event is titled Elseworlds, and will take place across three episodes - one each from Arrow, The Flash, and Supergirl.

The biggest selling point for Elseworlds, aside from seeing The CW's various DC superheroes working together again, is the introduction of Batwoman. Played by Ruby Rose, the character will make her debut in Elseworlds before going on to star in her own show in 2019.

While all that is happening, however, the Legends will be doing their own thing. Speaking to The Hollywood Reporter, Klemmer confessed, "I was happy to have sit this year out just because we only have 16 and our run of episodes was so tight and integrated. It's always a blast but it is a departure. I'm glad we got to do a straight run this year." He also revealed that 2019's crossover is already in development and there's a "loose shape for it." Whether or not the Legends will be a part of next year's crossover is currently unknown, but Klemmer says, "We're on standby."

rossover Doesn't Include Legends

Season 4 of Legends of Tomorrow will have a new lineup of superheroes, with Rip Hunter and Kid Flash exiting the show and Matt Ryan's John Constantine joining as a series regular. However, the supernatural detective won't be a part of the team right away. Klemmer explains that the writers wanted to build up some mystery around the character first: "That's something for the audience to have to unravel: What happened to Constantine during the offseason and why has he changed?"

The next season of Legends of Tomorrow will stick to a monster-of-the-week format, with the Legends investigating various magical creatures and discovering that the legends about them aren't quite accurate. Moreover, the team's attempts to figure out to do with these creatures will raise some thorny ethical issues, which Klemmer says made the show "much darker":

"With magical creatures, you're asking big questions like do they belong in our world? Is this really our world to police? We spent a ridiculous amount of time debating morality for a show that's a time-traveling action comedy. Is it fair to put a Minotaur in a cage at the Time Bureau? None of these things exist, but we're asking if a Minotaur has a soul and conscience."

While the Arrowverse crossovers can be a lot of fun, they also require getting all of the various DC superheroes together in one place, and can arguably be a distraction from the main series arc. From the sounds of it, the Legends have quite a lot on their plate already. Including a Minotaur.
