Sally Acorn (Dark Mobius) (Pre-SGW)

Past
Sally's early history was most likely largely the same as her Mobius Prime counterpart's. The point of divergence was when Knuckles became corrupted by his chaos powers and decided to conquer Mobius. In response to this, Sally would make alliances to combat Knuckles' growing forces and search for the Sword of Acorns to use against him, among other things. Also, despite warning Sonic of the risks of using the Chaos Emeralds to stop Knuckles head-on, Sally later received a letter from Sonic saying he was still going through with this plan (which ended in catastrophe). Eventually, Sally joined the countless heroes and villains alike that fell to Knuckles, now having assumed the mantle of Enerjak, and had her Core removed.

Legacy
After the loss of her Core, Sally's body was hung on the inner walls of Enerjak's Citadel like a trophy. During Enerjak’s final battle against Silver the Hedgehog, Sally's Prelate was summoned among a horde in order to overwhelm the young time-traveler, but to no avail.
