Vita is a new character introduced in Metal Slug Attack.
Vita is a Rebel Army cyborg. Parts of her have been replaced with mechanical componets, and she wears an eyepatch over her left eye. She has a mix of pink and yellow hair.
A member of the Rebel Army, Vita was badly injured in an unknown mission. Navy, a Rebel scientist, (the Professor was the chief during that time), successfully converted her into a cyborg. Initially, she was confused to why she was brought back to life and wanted to die, but Navy managed to persuade her to live with her actions.
Vita first appears in the Extra Ops "Signal Red", where she is sent by Morden to stop the Professor and the Martian Brain Robot. When she arrives, she battles and destroys the Brain Robot. The Professor attempts to attack Vita, but she quickly avoids his attack and knocks him out of his mecha. She is about to kill him when a Red Ring Laser Mecha appears, and after some communication, she spares the Professor and leaves.
She later reappears in the Extra Ops "Next One", where she controls a Nova clone to stop the Regular Army's new machine, the Slug Gigant MK II.
In the Extra Ops "Supply Lines", Vita is being outfitted with the ability to fly by Navy. She wondered what the button was for, and Navy told her not to use it. As she flew around the base, Rapid spotted her and asked her for assistance in disrupting the Regular Army's supply lines, which she accepted. Upon destroying the new attack helicopter, she rode on Rapid's train back to base.
Vita appears in the Regular Army story "The Sand Kingdom and the Golden Hero", where she is sent by Abigail to oversee Assy Nero, which Abul Abbas has borrowed from them. When Assy Nero gets critically damaged, Abigail orders her to retrieve the engine core before leaving.
She later appears in the story "Cross/You", where she assists Navy in destroying Anima. Her past and relationship with Navy are also revealed in this story.
In "Cleopatra's Pleasure Tour", she arrives when Nova appears and runs off. She persuades her to stop fighting and they talk about their pasts. Nova offers her the Union as a gift, which she accepts. When Cleopatra investigates the new source of energy (Nova and the Union) in the hopes of awakening her master, Vita and her soldiers try to stop her but are defeated.
