Just watched Justice League Unlimited S1:E3 and was thinking it would cool to have a Justice League series that had the characters at the pre-teen age like in the episode. Keep that style of cartooning and the same style of writing for it. Just thinking out load.
Justice League Action also has an episode where they are turned into kids called Trick or Threat. I like that spin too. I believe there’s more too. For sure there’s one in YJ where the kids disappear & the adults also. Misplaced is the episode name. They both exist on separate planes with Shazam being the only one who can pass between both due to his powers allowing him to be both.
That’s one of my favorite Unlimited episodes. The fact that the League themselves even behaved like children made it all the more entertaining.
