Heroes POV
You enter the portal, Metal is down for now, you're all tired and mourning Twister.  We have to get going, luckily we're in a world that seems to be a utopia, maybe another version of Mobius? It's advanced, maybe it's the future. You can only guess.
This AU's Heroes
There's not much after Chuck has taken over Knothole, you decide to go for a walk. You notice a group of people, tired and worn out, one holds a robot that seems badly beaten.

Villain POV
There's not many of you left after the takeover, there hasn't been much conflict. Everyone seems happy and cheery, you notice a group of people, maybe you could do something?

Heroes Goal: Find the next portal.
Villains Goal: Find out what these guys are up to.

You can play as this universe's version of your characters.
