Cibo is a main character in the manga BLAME! by Tsutomu Nihei. She is the head scientist of the Electronic Corporation in the Capitol and joins Killy on his quest for the Net Terminal Gene. Killy's first encounter with Cibo is in the lower levels of the Corporation in The Capitol, where she has been imprisoned for attempting to access the Net Sphere with an artificially created version of Net Terminal Genes. Her failed attempt to access the Net Sphere led to the appearance of the Safeguard, which destroyed the entire lab facility in which Cibo was conducting the experiment. The death and destruction resulting from Cibo's failed experiment led the governing body of the Corporation to convict and imprison her. Cibo's first form is the decaying upper torso of a woman kept alive by machinery inserted into her body. She convinces Killy to take her with him by stating that he needs her hacking skills to access the files he is looking for. Afterwards, she acquires a human form and destroys The Corporation's President with Killy's help. After the President's destruction, Cibo leaves the Corporation to travel with Killy because he is also exploring the City and is equipped with a GBE, the only weapon that can breach the Megastructure.
