I do know DC Lego sets exist but i never found out about a Lego set based on the Arrowverse. And NO i don't mean a Lego videogame. I mean a Lego set with real Lego pieces
Probably not going to happen. Closest we'll get is if that CW Flash cameo in the Flashpoint film is significant when those get sets. Though due to DC believing they are super dark, they aren't exactly rolling in kid friendly merch.
