Or if not that a new series continuing on, like JLU did too the JL. I've recently been rewatching it, so many good memories haha. It would be very good, if they kept the same voice actors etc. They could also include The Spectre, Presence, Anti Monitor and the other monitors etc.
Make a list of your favourite exclusive characters battling off (3 characters pre battle and there must be one ninentdo, sony and microsoft character). For exaple Kratos (PlayStation) vs. Mario (Nintendo) vs. Master Chief (Microsoft). And then tell me who wins and why. There are many possibilites so you should try.
