Princess Sally Alicia Acorn is the daughter of the King Maxmillian Acorn and sister to Prince Elias Acorn. She was sent to the sanctuary of Knothole Village by her father when the Great War was going badly for the Mobians, and led the Knothole Freedom Fighters against Dr Ivo Robotnik when he took power shortly after the Great War's end. Following the death of Dr. Ivo Robotnik, Sally temporarily assumed the role of leader during her father's health crisis. After he healed and resumed his role as king, Sally once again led the Knothole Freedom Fighters for a time, until the group was disbanded. For months her ability to work with the Freedom Fighters was limited, as she her royal obligations kept her occupied. This continued for over a year, until her brother took up the role as king. Sally returned to field operations, battling along side her long-time friends. But when Regina Ferrum, the Iron Queen, took over the Eggman Empire, King Elias ran with his wife and his son to keep them from harm. Sally temporarily took over the duty of monarchism and led the war against Regina, until her mother and father reclaimed the throne in order to allow Sally to fight alongside Sonic. The war against the Iron Queen ended when Sonic, after being told by Sally, had a one-on-one battle with Regina, which ended in Sonic's victory and Regina going into hiding.
The daughter of King Maxmillian and Queen Alicia Acorn, Sally was born during the Great War. In the first few years of her life, Sally lived carefree, unaware of the conflicts surrounding her. She would often accompany her father to Angel Island, where she first met Knuckles the Echidna. While King Max and Knuckles' father Locke would go off to discuss matters, Sally and Knuckles would keep each other company, forging a close friendship. However, after Sally's final visit the two would not see one another again for many years.
Back in Mobotropolis, Sally befriended the brash blue hedgehog called Sonic. The two would often play together in the royal palace and cause mischief. As the Great War escalated and Mobotropolis came under siege, Sally, Sonic and most of the other children in the city were evacuated to the safe haven of Knothole Village. During her stay there, Sally's mother and brother Elias, whom Sally had no memory of, were sent to Angel Island to hide during the remainder of the war. Their air craft was shot down however and the two were presumed dead for over a decade.
Following the end of the Great War, Sally and the other evacuated families returned to Mobotropolis. However, not long after this, the Warlord at the time, Julian Kintobor, unleashed in long-planned schemes of betrayal. Changing his name to Dr. Ivo Robotnik, he launched a full scale coup d'état, capturing Sally's father and rounding up millions to be roboticized. Present in the castle at the time of the coup, the five-year-old Sally was quickly taken to Knothole along with many other children by Rosie and Julayla where she would meet up again with Sonic and other childhood friends, including Antoine D’Coolette and Rotor Walrus. There they would remain in safe hiding and live free from Robotnik's tyranny.
Sally and Sonic were deeply inspired by the Original Freedom Fighters and their resistance of Dr. Robotnik. Following the defeat and disappearance of the Original Freedom Fighters, Sally forged a pact with Sonic and her friends to continue the fight in their stead. As early as age ten, Sally began leading the Knothole Freedom Fighters in their struggle against Robotnik.
After living in Knothole for some time, Sally's mentor and teacher Julayla grew ill. Sally had a deep respect for Julayla, and was deeply saddened when she died of old age. Before she died, Julayla gave Sally the Acorn Royal Signet and told her she was ready to lead the Freedom Fighters. Julayla also left for Sally a blue vest which she continued to wear for years. Immediately afterward, Sally was sent a "friend" in the form of NICOLE, a sentient compact super computer that originates from an alternative future where Sally is Queen. Feeling that her past self would seriously need a friend, Sally had Rotor design NICOLE and sent her back in time.
Leader of the Knothole Freedom Fighters
The ultimate goal of the Freedom Fighters was to oust the oppressive tyrant Dr. Robotnik and restore the Kingdom of Acorn. Hidden deep within the Great Forest in their rebel headquarters of Knothole, the Freedom Fighters carried out guerrilla attacks on Robotnik's operations. Seeing the Princess as a threat to his control, Robotnik made her capture a top priority. A scheme to replace Sally with a malevolent robotic double nearly worked, with a secondary plan of creating a whole line of robots modelled off of each of the Freedom Fighters lined up. The real Sally uncovered this plot, unmasked the fake Sally, and destroyed the rest of Robotnik's duplicates.
Robotnik later managed to infiltrate Knothole with a duplicate of Sally's father, King Max. The traitorous Freedom Fighter named Drago arranged for Sally's assassination, pinning the blame on Sonic in an elaborate frame-up: he had Hershey disguise herself as Sonic (though her mask was built with sensors to make everyone appear as Snively), and she came across Sally and cut her rope, and she fell and was apparently killed by the fall. Robotnik then appeared unexpectedly in Knothole after the fake King Max leaked its location. After arriving at the Freedom Fighters' doorstep and holding them all hostage, Robotnik announced his plan to use the rebel headquarters as a testing ground for his super-weapon, with which he intends to eradicate all non-robotic life on the planet. His "Endgame" scheme is nevertheless foiled by the rebellion, and Robotnik is vaporized during the weapon's backfiring. It is then revealed that the fall had actually rendered Sally comatose, and Sonic managed to revive her.
Rebuilding the Kingdom
In the wake of Robotnik's defeat, Sally worked hard to re-establish the old kingdom. The desolate wasteland of Robotropolis was difficult to rebuild, and discrimination against Robians threatened to spark a civil war. A new Robotnik arrived from an alternate reality and quickly retook Mobotropolis. He was destroyed in battle, but through the digital transfer of his mind into a new robotic body, he was able to live on as "Dr. Eggman". For a time, Sally presided over the newly-established Kingdom of Knothole, a haven from Eggman until he too, like Robotnik, learned of its location.
Return to the Frontlines
After Robotnik was killed, Sally was put in charge of reconstruction of Mobotropolis. With Sally busy behind the scenes, other Freedom Fighters took on the role of field commander, with Sonic himself occasionally filling that role. With the return of her parents, Sally could not properly rule either. Sally became frustrated with a lack of control over her life, which culminated in an arranged marriage with Antoine. After arguing that she alone has the right to choose her consort, she was threatened to lose her title by her own father. The marriage was made official years later when King Max was forced to step down due to a sudden illness. However, the day afterwards, the wedding was quickly annulled when her groom turned out to be Patch, an evil version of Antoine from a parallel universe. After her brother Elias took the throne and her father fell into a coma, Sally returned to taking a more active role in overseeing the Freedom Fighters, even joining them in combat.
Sally agreed to be the maid of honour at Bunnie and Antoine's wedding, with Sonic serving as best man. Not long after the ceremony, Sally became Eggman's prisoner during the aerial bombardment of Knothole, but was promptly freed by a rescue mission mounted by the few who weren't taken prisoner: Sonic, Tails, Knuckles, Amy, and NICOLE. With Knothole completely crushed, Dr. Eggman turned his sights on New Mobotropolis. Sally once more led the charge against the enemy forces herself, resulting in the Freedom Fighters and Chaotix defeating Eggman's Egg Beater battle suit. Just prior to this, her shoulder-length hair was restored to its original length and style by Bunnie, symbolizing that she was her old self again.
Not long after, she interrupted a duel between her brother Elias and Tails' father Amadeus Prower, both of whom were leading separate factions in a schism that threatened to plunge New Mobotropolis into civil war. Reminding them of her own ruling experience, she managed to bring the battle to an end and worked with them to establish a new system of government. Though the new ruling body called for seven council members-including Elias-Sally declined running, apparently quite fine with leaving politics behind for a while. Sadly, her relief at the averted crisis was short-lived, as Dimitri the Echidna arrived with horrifying news: Enerjak had returned.
After the Enerjak rampage and Mogul's escape, the latter then took over Robotnik's old Casino Night Zone and changed it to his own image. Meanwhile, Sally spent some time alone with Sonic in the ruins of Knothole talking about their past and feelings for one another. Their conversation was interrupted by Bean, Bark and the Destructix. Eventually, Sonic was knocked out by a shot from Nack the Weasel, who then gave Sally ten seconds to run for help while Sonic was dragged off by the Destructix. She soon liberated him with the help of Amy Rose and Geoffrey St. John. When the heroes confronted Mogul, however, he denied all claims of wrong-doing as his accusers lacked any incontrovertible evidence. Sally and her friends were then sent away publicly humiliated.
Following this, the Suppression Squad came to Mobius Prime through the Star Posts and began attacking Freedom HQ. Sonic arrived back at Freedom HQ just as Scourge emerged. Unfortunately, the Freedom Fighters found themselves matched blow-for-blow with the Suppression Squad, and the battle was taking its toll on the base so Sally convinced Sonic and the rest to retreat.
Later, Sally told Sonic he was being sent on a mission to invade Anti Mobius with Amy Rose. While they were gone, Miles from the Suppression Squad was sent to bomb New Mobotropolis. Sally and the Freedom Fighters arrived on the scene, only to find that Miles was actually willing to propose an alliance against Scourge. After Miles explained how Scourge took over their world, Sally agreed to help him.
However, the Freedom Fighters and Suppression Squad were no match for Scourge. After Sonic returned to take on Scourge, they were both blasted by Boomer and thrown back into Moebius by Miles. Afterwards, Boomer shut down the star posts; therefore, Sonic and Scourge were unable to return to Mobius.
Sally and Alicia ended up arguing about stranding Sonic and Amy in Moebius, but the two were interrupted when Rob O’ the Hedge and Silver the Hedgehog arrived. Sally proceeded to explain to them what had happened to Sonic and Amy and how they were stranded in Moebius. Silver then used the warp ring to go there with Rob O' the Hedge. Sally then told Tails to start fixing up the Star Posts.
Shortly after Tails had repaired the Star Posts and they went through them to Moebius, the Suppression Squad and Freedom Fighters where ambushed by Super Scourge and he tried to injure the cowardly Miles, but Silver used his psychokinesis to grab and hold Scourge before he could, but he managed to break free nonetheless. Sally then ordered Silver to try this again so the others could pile on top of Super Scourge long enough for him to lose his super form, but Silver's power failed him yet again and Scourge threw the others off of him. Scourge was later defeated thanks to the quick thinking of Sonic, as the Anarchy Beryl drained Scourge of his strength when he powered down. Sally then walked back with the others to Dr. Stickman's tower to go back to Mobius via the Globe Posts.
Tried for Treason
After returning from Moebius, Sally was brought before the Council of Acorn to a hearing to see if they should arrest her for going against their orders of not retaliating against the Suppression Squad and not attacking Dr. Eggman, with her former student Hamlin Pigg as the prosecutor. Some even thinking her actions could be some part of a royal conspiracy. The council almost arrested Sally as the case against her was too strong, but Sally said that she would always wait for the orders of the council, even during a battle, to not make the same mistake twice, and would neglect to go to the Chaotix for any future help. Or that the council could trust her with the duty she's had all her life and drop the charges. Everyone but Hamlin then voted for the charges against Sally to be dropped. She later spoke with Hamlin who revealed that he only tried to arrest her because if he could not make sure the battles were fought properly on the field himself, as he was the substitute that never went into battle and was always forgotten, then he would see to it that the Freedom Fighters did.
Battle to Bring Down Eggman
The next day, Sally led the attack against the Egg Dome, commanding both the Knothole Freedom Fighters and the Chaotix. Using her tactics, both teams managed to defeat the Dark Egg Legion and force it into retreat. Before they could get the group to surrender, the Egg Phoenix showed up and began attacking. Sally came up with the plan to have Sonic distract Eggman while Ray, Charmy and Saffron planted Tails' Neutralizing Mines. After the Egg Phoenix was destroyed, Sally ordered the groups to set up camp for the night, as they were all battle-weary (except Sonic). The next day, Sally assisted Rotor in setting up her plan to have the citizens back home view the final battle stating to Sonic that the people had a right to know. After making their way inside she helped command the Freedom Fighters and the Chaotix in their attack. However, they found they could go no further because of a barricade Espio stated was meant for Sonic to spin dash through. Sonic decided to take the invitation with the rest coming in later to back him up, though Sally was against it, however Sonic reminded her that this was how they usually fought. Sally reluctantly agreed giving Sonic a hug and telling him to be careful before he left.
After Bunnie and Mighty finally managed to pull the doors apart she ran ahead to see if Sonic needed any help only to find Eggman in a state of insanity. After Snively told them that Sonic "broke" Eggman and that they had won, the Freedom Fighters were delighted. However, Sally noticed that Sonic was feeling uneasy about his victory, having not won in the way he was expecting. Wondering what he should do next, Sally, hoping to comfort him, told him that moving on was the best thing he could do. They then joined the two teams as they returned home, unaware of the new threat that had just arrived at the Eggdome.
During the celebration of Eggman's defeat, Sally attempted to get Sonic to enjoy himself, while he mulled over Eggman’s descent into insanity. However, before the Forget Me Knots could start playing, Monkey Khan violently interrupted, chastising the heroes for celebrating while other parts of the world were in turmoil. Sally was surprised by Khan's appearance, but Sonic simply attempted to attack the cyborg. Fortunately, Sally intervened before physical contact could be made. Sally attempted to explain to Khan that Eggman had been defeated, but Khan stated that a mere change in management had taken place, and the Iron Dominion was now in control of the Eggman Empire. While Sonic and Khan decide to attack head-on, Sally tries to warn them of the dangers they might face, but her warnings fall on deaf ears, with the two fighters leaving to fight, while Sally stays, worried.
When Sally catches up with Sonic and Khan and learns more about the Iron Dominion, she suggests that they team up with resistance groups in the Dominion’s former region, but Khan says that they have all surrendered. As the two prepare to leave, Sally begs Sonic not to go, as she considered the Iron Queen extremely dangerous. But Sonic reassured her that he would be fine, and left an extremely worried Sally.
While Sonic and Khan approach Mobotropolis, Sally stayed in Castle Acorn with Elias, Knuckles and the High Council, discussing why Espio would be involved in a ninja clan. Soon, a beaten up Sonic and Khan arrive. Sally comforted Khan, who was upset with his failure at not defeating The Iron King.
