Mecha Sally

Mecha Sally is the roboticized version of Sally Acorn which been assumed two times. The first was during the First Robotnik War in a failed attempt to sabotage Dr. Ivo Robotnik. The second time was as an act of sacrifice during Dr. Eggman's attempt to roboticize all of Mobius. Dr. Eggman took advantage of this situation and heavily modified Mecha Sally to become one of his premier weapons, knowing it would be very difficult for Sonic and the Freedom Fighters to stand against one of their dearest friends.

Becoming the Enemy
After Sonic and Dulcy found a portable De-Roboticizer, Sally volunteered to be roboticized so they could sabotage Robotnik's headquarters right under his nose, and then be reverted back to normal later. Sally allowed herself to be captured while equipped with a Neuro-Overrider, but did not realize the device fell off of her, and was completely subjected to the roboticization sequence, losing her free will just like all the other Robians. Now dubbed "Robot Number Three-Three-Nine-Zero" by Robotnik, Sally revealed the secret exit to Robotropolis where she was to meet the Freedom Fighters, and held them at gunpoint while waiting for Sonic. Upon arriving, Sonic saw his friends captured by Robotnik, Snively and the robot Sally. After the Freedom Fighters refused to tell them where the De-Roboticizer was, Robotnik ordered them all to be roboticized at the hands of Sally herself. Fortunately, Dulcy came in the nick of time with the De-Roboticizer, and turned Sally back to normal with it just as she was about to roboticize her own allies. (StH: #29)

Sally's Sacrifice
Years later, Dr. Eggman initiated Operation: Clean Sweep- a diabolical plan that involved using the Death Egg Mark 2 to roboticize the entire planet, which would result in the destruction of entire communities and cause the deaths of countless lives. Sally went to stop the roboticizer as Sonic fought Dr. Eggman and his Sonic robots, but when she hooked Nicole into the system, found there no time to find a way to block the weapon's command signal or otherwise prevent its firing. Nicole believed the only option available would be to invert the beam, and Sally without hesitation ordered her to do so, setting up a manual executable before ensuring Nicole's core programs would be safe back in New Mobotropolis. Nicole protested as Sally would not be immune, but she told her friend that this was their only opportunity to save everyone with it and she needed Nicole's help to do so. (StH: #230)

Once Nicole had finished her download, Sally held back her tears, steeled herself and executed the program just as Eggman ordered the World Roboticizer to fire. The roboticizer fired, but rebounded into it's own chamber, causing a large explosion and destroying much of the machinery. Sonic and Eggman survived, struggling out of the rubble as the hedgehog mocked the doctor for once again having a plan thwarted by the heroes. However, Sally suddenly emerged from beneath the rubble, roboticized completely subservient to Robotnik's will. The shock of this development had Sonic struck with horror and Eggman cackling in delight as Mecha Sally reached for the stunned hero, coldly saying, "Hedgehog. Priority one." (StH: #230)

Mecha Sally then seized Sonic by the throat, as he pleaded with her to resist Eggman's control, begging her not to make them fight. Eggman, delighted over the turn of events, wanted to enjoy this though he knew it would be sensible to have her march them both into an incinerator, and had Mecha Sally throw Sonic out of a waste disposal hatch. She then accompanied Eggman (who commented about finding a better name for her than 'Mecha Sally') to the bridge of the Death Egg where they were met by Snively. When Snively objected to Eggman's order to launch an assault on New Mobotropolis, stating that the Death Egg was too heavily damaged, Eggman had Mecha Sally grab him by the collar of his uniform and demand that he follow her master's commands. (StH: #231)

Upgraded Enforcer
Hoping to fully take advantage of the situation, Eggman opted to upgrade Mecha Sally and spent an excessive amount of time on the process while leaving the Death Egg's repairs to the Egg Mites, much to Snively's frustration. His modifications included weaponizing her and adding armor plating to make her more streamlined, along with a rocket-powered flight system and a Power Ring as a special power source, noting that it would not risk restoring her free will. (StH: #232, #233)

Once complete, Dr. Eggman deployed Mecha Sally along with Metal Sonic v3.5 to intercept former king Elias Acorn and his wife & step-daughter while relocating from New Mobotropolis to Feral Forest. Mecha Sally and Metal Sonic began their assault in an attempt to eliminate the former king, but the Acorns were being protected by the remaining Knothole Freedom Fighters, and her appearance brought a mix of anguished reactions from her former friends. Sally proceeded to remove enemy air support by targeting Amy and Tails on the Tornado as children did not belong on the battlefield, and then took Bunnie out of the fight with ease, noting she was no threat without her cybernetics. Once Dr. Eggman changed their objectives, she attacked Sonic as he attempted to stop Metal Sonic from destroying the Mobo-Cruiser, and Sonic's efforts to reach the Sally he loved were to no avail. She proved to be a superior opponent for the hedgehog as she was able to keep him occupied, forcing Antoine to save her brother's family and take the blast from Metal Sonic's self-destruct. As Sonic looked on in horror while being held by his throat yet again, Mecha Sally coldly stated the Sonic would "join him soon." She then retreated from the battle after her master recalled her back to the Death Egg, leaving the grieving Freedom Fighters to deal with their loss. (StH: #234)

Not long after this, Eggman later unveiled Mecha Sally to his assembled Grandmasters, presenting her alongside other Metal Series robots as enforcers to "help" ensure the Dark Egg Legion chapters were performing effectively. Upon dismissing the Grandmasters, Eggman then had Mecha Sally accompany him aboard the Egg 'Stache Flyer to pursue Snively as he fled. (SU: #37)

While searching for his nephew in Central City, Eggman unleashed Mecha Sally and Metal Sonic v3.6 to provide support for his forces. After Omega began to overpower the Egg Paladins, Mecha Sally swooped in from behind to attack and knocked the robot down. Seeing the roboticized Sally now serving Eggman shocked even the E-100 Series robot, who wanted to rescue her. When his former master informed him that it was impossible, though, Omega contemplated that destroying her might be more merciful in order to spare the former princess. However, Mecha Sally and Metal Sonic were able to take Omega by surprise and attacked him using their laser cannons. As Snively attempted to escape, again, Mecha Sally and Metal Sonic effortlessly destroyed the G.U.N. fighters sent out to bring down Snively's craft before returning to the Flyer and continuing the chase. (SU: #38)

Arriving with Eggman in the Dragon Kingdom, she was sent out to confront Monkey Khan. She started to have difficulty fighting him since her Power Ring was practically all used up. Khan selflessly gave up his Power Ring crown in order to save her life after Eggman explained to him that she would die without one. After being restored, she grabbed Khan's throat. She then got crushed under some trees along with Khan when Snively arrived with the Iron Oni. (SU: #39)

Abilities
Sally's strength is greater now than it ever was in her normal form. Eggman modified the current Mecha Sally with new abilities, including prevention of restoring her free will, rocket-powered flight via boot jets, and sword-like blades mounted in her forearms which retract when not in use. She also has a powerful laser hidden inside one of her locks of hair. She primaraly uses the laser as part of a combo attack with Metal Sonic. Mecha Sally also has the ability to project a powerful force field around herself, shielding her from enemy attacks. In addition, Mecha Sally still remembers and possesses her formidable martial arts skills as she was able to back flip kicked Omega to the ground, a move she once used on Knuckles long ago before being roboticized a second time. It is possible that like Metal Sonic, she is capable of using her claw-like fingers to slash opponents. (StH: #232, #233 #234, SU: 38, SMM)

Personality
Cold and efficient, Mecha Sally is completely loyal to Dr. Robotnik and follows his orders without question or hesitation, even going as far as betraying the ones she had considered her friends. She also engages her opponents psychologically; delivering cold, merciless ridicule of their weaknesses while attacking them.

Appearance
In her first appearance, she appeared as a robot version of herself.

Her second appearance is similar to her first appearance, except for the fact that when first roboticized, her eyes became red on black, while currently, they're blue on black, as well as being more detailed and mechanical-looking.

After Dr. Eggman upgraded, modified, and weaponized her, Mecha Sally still has her metallic blue vest, but her hands are now silver, her midsection is silver with a black and red crystal or panel underneath her vest, black boots, black shoulder guards in place of the round brown shoulder guards, and blue legs. In addition, her cheeks now have silver disks instead of her original brown disks. Her tail is still brown.
