For the Earth 3 bros on here, solicitations have unveiled the doppelganger world's heroic faction to rival the Crime Syndicate. I know this is just a mini, but I'm having fun with it enough that I hope it gets extended.
>"The Crime Syndicate crosses the line for the last time…and Alexander Luthor demands justice! Earth-3's Luthor, Savanna, Venus, Power Tower, Red Hood, Lonar, and Thaal Sinestro band together to form the Legion of Justice and defend their world at all costs. Will the looming threat of the Legion stand in the way of Owlman, Superwoman, and Ultraman's quest for global takeover? It all builds to a cliffhanger that will leave you on the edge of your seat!"
"Lonar" confuses me, as does the guy on the horse. Is the cat hero supposed to be a flip on Cheetah or Catwoman?
