The Justice League begins as industrial saboteurs. Impulse, Green Arrow, Superman (not code-named yet), Aquaman and Cyborg are walking away from a burning Luthorcorp facility. Chloe assists and is code-named "Watchtower." Lex aims to raise a super-powered army to fight these "terrorists." Lionel covers for Clark with Lex.
GA will lead the team against Lex in Corto Maltese while Clark continues to hunt Zoners. Ollie and Lois are finished. We knew that that had to happen. We did not expect the JLA to start before CK had donned the costume but this is a different version of the story.
