The place: A nexus in space-time, ripping individuals from their respective dimensions and timelines, to work as an interdimensional police force. Individuals chosen are selected for flexibility of mind and ability to get the job done or at least that’s the criteria the sentient AI in charge of the Rift claims to use. Assisted by Intercept, a mutant from Earth-1723, the AI monitors a slew of dimensions for dimensional destabilization and dispatches teams to deal with it. The Rift, as the group’s base is called, exists outside time and space and provides room, board, and recreation for the teams. Somehow it still gets decent television reception, though flipping through the channels is not for the faint of heart.
The people: Any potential variation of a character from whatever world you can come up with
The pitch: If you’re familiar with the Exiles, this concept rides closely to that, though with decidedly less Quantum Leap random jumping. The concept is for teams (large or small) to cross into a dimension to stabilize it and apprehend some villain trying to take advantage of the dimension’s structure or setting to do “bad things.”
