Sally is a new character introduced in Metal Slug Attack.
A young assassin, Sally was hired by the Ptolemaic Army to protect Lord Ptolemaios from those who would harm him behind the scenes. Mira rewarded her talents by subjecting her to an empowering ritual, which she took. As a result of the experiment, she has an insatiable appetite for blood, superhuman strength and speed and her eyes have become blood-red.
Her clothes are gothic-themed and she puts an amaryllis motif ornament on her hair when going out on missions. The scythe she uses is her most favorite and regularly used weapon, with the blood of slain enemies soaking its blade red. It also has a skull motif.
Sally makes her first appearance in "Killer Scythe", where she is called in for a mission to hunt the Red Goblin. She is slightly upset that she has to bring the Ptolemaic knights as her support, and gets into several humorous accidents while preparing.
Eventually, she arrives at the town with Maria, her partner for the mission. They soon find one red-haired man, who Sally believes to be the Red Goblin, though Maria knows it isn't who they're looking for. Roberto's partners, Eri and Tarma, arrive to defend him. Sally avoids all of Eri's attacks while Maria battles Tarma. During the battle, Maria notices another red-haired man with a woman, prompting her to leave and pursue them.
Sally soon notices that Maria is gone and wondered where she went. Tarma tells her that she saw someone else and chased after them. Sally decides to withdraw so she can catch up with Maria, though she warns them they were lucky to be alive.
- She bears a resemblance to Kurumi Tokisaki from Date A Live and Nico Yazawa from Love Live!.
