Vita is a villain and playable character in Metal Slug Attack. She is a soldier in the Rebel Army who was badly injured in an unknown mission and rebuilt by the scientist Navy as a cyborg.
Vita sees herself as a cog that must perform its duties, and does not mind sacrificing herself for the Rebel Army's cause.
Vita was sent by General Donald Morden to stop the Professor's Martian Brain Robot. Vita fights and manages to destroy the robot before being attacked by the Professor in his mecha. Vita then knocks the Professor out of his mecha, but ultimately chooses to spare him.
Vita controlled a Nova clone and used it in an attempt to stop the Regular Army's Slug Gigant MK II machine.
The Sand Kingdom and the Golden Hero
Vita was sent by Abigail to oversee Assy Nero after Abul Abbas borrowed it from them. She confronted Regular Army soldiers, Eri and Fio in a tunnel to battle them. While she at first had the upper hand in the fight, El Dorado appeared and gave Eri the Slug Gunner, evening things out to an equal playing field.
Vita then fought Eri in a close battle that ultimately ended in her being defeated. The cyborg attempted to self destruct, but was called back before she could do so.
Vita was then ordered by Abigail to retrieve the core of the Assy Nero. Disappointed that Abul had allowed the Assy Nero to be badly damaged, Abigail revoked his control of Vita. Abul pleaded with Vita to save him, but she calculated that there was only a 20% chance of saving Abul before being intercepted by the Regular Army and decided to abandon him.
When Navy set out to destroy the White Baby controlled Anima to prove herself better than the Professor, Vita accompanied her. Upon Navy and Vita's arrival at the ruins, White Baby attempts to overwhelm her mind but Vita deploys Sanctuary to protects her. Navy's forces are then attacked by brainwashed Amadeus researchers but Navy and Vita fight them off. White Baby goads them to hurry up, causing Navy to deduce she had a personality modifier, but Vita believes it to be real emotions.
As the two traverse towards White Baby's location Vita detects several Amadeus robots ahead and prepares to fight them, but Navy battles them instead. She soon notices that the robots are regenerating and Vita notes that they usually don't have a repair function. Navy then states that Anima focuses on destruction and regeneration, and theorizes that White Baby has overwritten them with a program. Vita decides to run past the robots, to which Navy agrees and follows her. Navy and Vita eventually reach White Baby and Amadeus. While Navy gets into a hostile exchange with Amadeus, Vita is asked by White Baby why she is with a human, to which Vita tells her that humans are stronger than she thinks before battling her. After White Baby runs off, Anima breaks free of White Baby's control and goes rampant. Navy then battles Anima with support from Vita and together they destroy Anima, which Amadeus notes will now take years to recover. Following its defeat, Navy then gets into another argument with Amadeus over whether she's the "best" while Vita looks on. In the Secret Ending, Vita is approached by Allen Jr. when he comes in for an energy booster and tells him that Navy is not here. However, Allen Jr. just asks Vita to bring him an energy booster. Vita takes something and shows it to him, but Allen Jr. refuses it as it has a skull mark. Vita then grabs another container and shows it to Allen Jr., who notes that the color is right but is still suspicious of it. Vita then takes it back from Allen Jr. and drinks it, causing her to fall unconscious from it.
