mecha hisui
Mech-Hisui (メカヒスイ) is a character from Melty Blood, a spinoff of Tsukihime. She is voiced by Miyu Matsuki.
Mech-Hisui is a robotic clone of Hisui, create by Kohaku under the influence of the TATARI phenomenon. All mass-produced Mech-Hisui are designed to show complete subordination towards "Doctor" Kohaku.
As a robot, Mech-Hisui is designed with stereotypical anime robot qualities, including eye beams, weapons hidden in her hands, being equipped with a jetpack, and having attacks which reference famous robots from classic anime, such as God Gumdam's Bakunetsu God Finger.
A second Mech-Hisui, who is shown to be in the possession of Nekoarc, was introduced in Melty Blood: Actress Again. This Mech-Hisui has assumed control of it's personality, which results in showing highly rude interactions towards Nekoarc.
