Sally Acorn

Sally Acorn is a character in Sonic the Hedgehog and Sonic Universe. She is princess of the House of Acorn and member of the Freedom Fighters.

Pre-Worlds Collide
Sally was the daughter of Max and Alicia Acorn and sister Elias Acorn. She was the founder, along side Sonic, of the freedom fighters and continued to lead for time.

Later on, when attempting to stop Doctor Eggman's roboticizer after the first Genesis Wave, Sally stops in by inverting the beam resulting in her roboticization into Mecha Sally. Without her free will, she would often aid Eggman in fighting against her former friends, including Sonic. (Sonic the Hedgehog #230)

Mecha Sally and several Egg Swats were sent to stop both Team Freedom and the Arctic Freedom Fighters when they made it into the base in the Northern Tundra. She was disabled psychically by Silver the Hedgehog. Shortly after this, Eggman the second Genesis Wave changes the world. (Sonic the Hedgehog #247/FCBD 2013)

Worlds Collide and Aftermath
During Worlds Collide, Mecha Sally appears briefly in a flashback in Mega Man #26 and in Eggman's fantasy in Sonic the Hedgehog #251. With the history of the world altered after the crossover, Sally is no longer roboticized. (Sonic the Hedgehog #252)

Abilities
Sally is a skilled tactician and a formidable combatant, with her fighting abilities enhanced by her signature Ring-Blades following the changes to reality.
