Mech-Hisui

is a character from the Melty Blood games.
==Profile==
===Background===
Mech-Hisui was created by Kohaku as the ultimate weapon in her "" in the "G." and "Oh my sister!" routes of Melty Blood. Though normally portrayed as a schemer, it was only after becoming TATARI during the Hologram Summer that Kohaku gained the capability to create robots in the "" under her "Magical Amber" persona. Mech-Hisui was completed during the single night along with Kohaku's various inventions due to Miyako Arima viewing Kohaku in such a way.
===Personality===
Mech-Hisui has little personality at first, only voicing brief orders and programs to execute. She gains more of a personality in subsequent games, jesting against opponents and acting out against her creator. She refers to Kohaku as "Doctor."
===Appearance===
Mech-Hisui has short violet hair, wears a white lace veil on her head, cinnamon long-sleeved dress with a crimson bow on it, white apron, black tights and black mary jane shoes.
==Role==
===Melty Blood===
After Shiki Tohno, Akiha Tohno, and Sion Eltnam Atlasia escape from the Tohno Mansion basement during Kohaku's "Tohno House Subjugation Plan", they are confronted by Mech-Hisui and Kohaku. Kohaku command her to inflict the most non-fatal pain possible, but she is ultimately defeated. She instantly initiates her self-destruct program and targets Akiha, which is little more than a flash grenade to allow for Kohaku to inject her.Melty Blood - Block J: 4/Fight On, Our ○○○○ Hisui - M X M X M X M
===Melty Blood Re-ACT===
Mech-Hisui's arcade mode begins with her beginning a patrol of the town after finishing charging. Kohaku tells her to patrol thoroughly while checking on suspicious people, which she interprets as "seek and destroy all enemies." She encounters Neco-Arc, identifying her as a "Maximum Priority Target" to destroy. She encounters Neco-Arc again, who refers to her as a rival. She cannot compute Neco-Arc's nonsensical rambling and requests a logical explanation from Kohaku. She rejects her analysis of Neco-Arc after detecting that her mass is increasing, identifying her as an absurdity.
Appearing before White Len, she mistakes her for Len and requests that she return to the mansion. White Len is baffled by her appearance, but simply decides that she is an enemy. She finds Shiki and Len lying unconscious near Aoko Aozaki, who is also baffled by the robot. Mech-Hisui activates her protection program despite Aoko's protests, identifying her as an enemy of unknown affiliation. Her ending parodies a super-robot show, with an announcer declaring that Misaki's peace has been protected. He then notes hundreds of Mech-Hisui descending on the town and Kohaku riding a giant version, giving the townspeople sympathy.
===Melty Blood Act Cadenza===

Mech-Hisui's arcade mode begins with another patrol of the town. She encounters Neco-Arc once again, who claims that she won't be beaten again. She analyzes that Neco-Arc's defensive strength is down by half from the previous fight, and promptly denies any possibility of winning. She returns to Kohaku afterward, and Kohaku notes that the data will help make a third-generation model. Mech-Hisui then rebels after claiming future models will be unneeded. Her current line plans to confine their creator and rule the world in her place. They defeat her, quickly rushing to gain air and ground supremacy with their numbers. They begin in their plan to subjugate the human race, while Kohaku laments her fate.
==Abilities==
Mech-Hisui is a built by Kohaku. She was completed by the mad doctor Magical Amber after she became one with TATARI just in case her and Hisui couldn't defeat Shiki Tohno and Akiha Tohno. It should be noted that by this point Hisui and Kohaku were powerful enough to receive attacks that could stop Ciel or Nrvnqsr Chaos in their tracks without taking damage.Melty Blood - Block F: 3/What Is This - dead end love song!

Mech-Hisui is equipped with an Attack program. In Melty Blood, she is ordered by Magical Amber to fight serious Akiha, Shiki Tohno, and Sion Eltnam Atlasia simultaneously inflicting an amount of pain that will not be fatal. While she is defeated, Shiki states that it was a very taxing battle, both physically and mentally.
After being defeated, Mech-Hisui's System shutdowns and she executes her Kamizake function. While she locks a target when she self-destructs, in truth, it isn't lethal, as it just consists of a .Melty Blood - Block O: 5/The Strongest Enemy - G.
==Forms and Alternate Versions==
Originally a one-of-a-kind weapon, Kohaku eventually enters the mass production phase of building them. As they receive version upgrades with every new iteration of Melty Blood, there is likely a new model being made in the factory.
===Giant Mecha-Hisui===
The enormous Mecha Hisui that appears in her ending is a model. Described as a Mobile Armor. There shouldn't have been more than one built in Melty Blood Re-ACT, but for some reason it seems that in Melty Blood Act Cadenza there's already a mass-production infrastructure in place.
==Development==
There were originally two versions of Mech-Hisui during the development of Melty Blood Re-ACT, called "Real Type" and "Super Type." The Super Type would have had an ability like a rocket punch, a super radio wave tornado, and an erupting god finger. Nasu would have liked to use it and hopes for the chance in another version. The giant version and the ending in Re-ACT are a parody of .
