Parallel universes are universes in a different timeline to Dredd's own, where events have turned out differently. The theory was that a slight change in probability or human action - i.e. you go left instead of right - will spawn a new one, but Mega-City One scientists have lamented that they instead keep finding universes fundamentally different to their own, where "all life is a crime or men dressed as bats are deputised".
Alternate universes include:
- Macro Zone Alpha, where everyone is inherently nice and peaceful.
- The timeline of Johnny Alpha from the series Strontium Dog.
