The Flash is coming to Gotham City for the season finale of The Batman! Consider this a reminder that part one of "The Joining" airs this Saturday morning at 10:30am on the CW. The Martian Manhunter will be teaming with the Dark Knight, but the story will conclude on May 5th in an episode that will reportedly feature a cameo for the fastest man alive, among others. When the Comics Continuum asked Executive Producer Alan Burnett if the crimson comet would be putting in an appearance he coyly replied, "Flash? Maybe. You just might see him." TV Guide has a preview of the episode and of The Batman's upcoming fifth season, in which the Justice League will be frequent guest stars. Newsarama notes that the April 30th issue of TV Guide includes a peek at how the Flash will appear in The Batman's animated universe.
As the fourth season of The Batman (Saturdays at 10:30 am/ET, on the CW) winds down, the Caped Crusader is starting to make some superfriends. In the two-part season finale, which begins this Saturday and concludes on May 5, Batman joins forces with Martian Manhunter to stop an alien invasion in Gotham City. And that's just the beginning: When the show returns this fall for Season 5, a parade of superheroes will guest-star. "Martian Manhunter is starting the Justice League," executive producer Alan Burnett says, "and he would like nothing better than to have Batman on the team." Also on the guest list: the Flash, Green Lantern, Green Arrow, Hawkman and Superman.
