Arrowverse

@sahara Well technically yes as He had a cameo in the crossover event as they traveld to earth 666. So basically earth 666 is one of the earth in the multiverse set in Arrowverse, but I think that basally it, don't think that they will do more than that, same goes to Titans and other show. I think that I just wanted to establish that they exist in the same multiverse. (but you never know)
