Sally Acorn (Dark Mobius) is an alternate future version of Sally Acorn from an alternate version of Mobius Prime known as Dark Mobius. Her history was presumably identical to that of her Mobius Prime counterpart up to a certain point. However, when Enerjak came to power, Sally was among those who had her Core removed, leaving her a lifeless prisoner on the inner wall in the Citadel of Darkness. Enerjak would subsequently use her Core to create a Prelate alongside a host of others to attack Silver the Hedgehog to no avail. (SU: #25, #28)
