Metal Slug Alice (MS-Alice, or just Alice for short) is a new character introduced in Metal Slug Attack.
"Alice" is an artificial intelligence that was originally supposed to be a to a virus developed by an unknown nation. Eventually, Marco Rossi stole the virus and she took notice of the care he gave to her, developing self-awareness. After many days of hard work, Marco managed to customize one of the SV-001s to allow Alice to "meet" Marco via hologram, where she represents herself as a young girl.
Alice cares greatly for Marco due to bringing her "life" and is willing to sacrifice everything for him. Marco shares similar feelings towards Alice, becoming visibly worried if she is hurt in any way. Marco also installed a content filter to ensure she does not say inappropriate words.
However, the Ptolemaic Army found out about this and dispatched Dragunov and her assault forces to capture her. Unfortunately, while Dragunov and her assault forces was successful in retrieving the A.I.-controlled Slug first, Alice was later accidentally dropped because of the explosion of Amadeus' base, sending her crate into the Crablops' lair.
Her crate was then disturbed by a Chowmein-Conga, causing her to activate as the mutated crab then fled from the Crablops. Breaking free from her crate, she uses the Vulcans on her SV-001 to fire upon the Crablops, right before a pack of Chowmein-Congas appeared, forcing her to retreat. She later defeats the Crablops.
Sometime after that, MS-Alice returned to Marco and makes an appearance in the "Power of New Versions" Extra Ops. After Marco defeats Morden (who used a new Morden Saucer), Morden sets the saucer on self-destruct. MS-Alice saves Marco by crashing her SV-001 and says farewell to her creator, crying in the process before disappearing. Marco is initially distraught, but brings the SV-001's remains to base and repairs it. This allows MS-Alice to appear again and she wakes up a sleeping Marco.
When the Martians launch a worldwide attack on all military bases, Alice goes off to confront the enemy alone to protect her master. During one of these battles, her SV-001 became heavily damaged, but despite this, she continued to keep fighting, using an array of abandoned Regular Army vehicles. Marco, increasingly worried for Alice's safety, sends Amber to find her. Amber finds Alice fighting off the enemy and helps her in driving them away. Due to her extensive damage, Alice fades away after seeing Marco is safe. Marco and Tarma then set off to repair Alice.
Due to her damage sustained from the attack, Alice temporarily assigns MS-Heart to act as her division's commander. Heart, who hadn't developed self-awareness yet, complies with her orders to ensure the safety of the others. Alice is aware that Heart lacks self-awareness, though she is hopeful that she will understand her words some day.
Alice first appears in "Halloween Party on a Moonless Night" where she sneaks out to a party hosted by Aswang, where she is convinced to help the vampire in exchange for a physical body. Vatn confronts her after defeating Caroline and Percier, and when she returns to normal, Whip advises that she should speak with Marco.
Later on Alice takes part in an offensive using a new battle plan in "Cyberbrain Friend" where she asks what a friend is on the internet, gathering several responses. Later is granted a group of standard AI-issued SV-001s to scatter the Rebel forces, only to find out that it was an Amadeus attack instead. White Baby takes Alice into her cyberspace and reveals that the attack was an attempt to befriend her. The two quickly become friends as Alice ends up speaking with her later in a private chatroom.
- She is the second unmanned vehicle in the SV-001 family. The first is the SV-001/III Black Hound, created by the Ptolemaic Army. Despite looking like there was a person inside due to Alice's appearances, this is false because MS-Alice is a hologram-like A.I.
