Future Gumball is the brother who's in command. He controls everything and handles the problems he and his brother, Future Darwin, get caught-up in. But he's still not very smart.
Future Darwin is the brother who stays in the shadows. He doesn't talk much except when he feels threatened, and usually stays-out of Future Gumball's way. He isn't very smart as well.
