Batman: The Brave and the Bold

Batman: The Brave and the Bold is an American cartoon/comic series created by Warner Bros. Animation and DC Entertainment.

Synopsis
Each episode of Batman: The Brave and the Bold features the main character (Batman) teaming up with other minor characters from the DC Universe to thwart minor villains or to solve crimes. Most episodes have a cold open with an escapade not related to the remainder of the episode. In the first season, the villain was Equinox, who later returned in "Time Out for Vengeance!"; and in the second season, the villain was the alien Starro. During production, the show's creator said that if a character's cold open appearance was deemed successful, then it may warrant exploring the character further in a future episode's main adventure.
