Casi, known in Japan and some US & UK games as Charu (チャル), is a computer program that takes the form of a human girl. She appears to help out whenever she can or assists the Professor.
Casi is a pale-fair skinned girl originally with big violet eyes that became green over time, and long flowing green hair usually worn straight down or in a ponytail.
In Ape Escape and Ape Escape: On the Loose, Casi wore a black spandex outfit with white cuffs below her shoulder and around her neck, and the Professor's insignia on her chest. She also wore white socks with red, white, and black shoes, two red bracelets, and a pair of red and white circled ear pieces.
In Ape Escape: Pumped & Primed, she wears the same outfit, but now has a spider motif.
In Ape Escape: Million Monkeys, she wears a sleeveless white shirt with blue short shorts.
Casi is a helpful girl who appears to be formal with others. She is a nice, but quiet girl. She is a loyal assistant to the Professor and is also not quite as pushy as Natalie.
