Cow is one of the two main characters in Cow and Chicken. She is voiced by Charlie Adler.
Cow is Chicken's 9 year young sister, with a weight stated as 600 pounds. Cow looks up to Chicken, who she refers to as "Big Brother". She is often viewed by Chicken as infantile and stupid, and is quickly prone to emotional outbursts. She is the only character to appear in every episode of the show. Cow has employed Blackmail to get Chicken to do what she wants and often attempts to get the other characters to do the right thing. She also enjoys drinking her own milk and holding her teets. Her frequent quote is "Fairy Princess!" whenever she sings in excitement. Cow's alter ego is "Supercow", a superhero with the ability to fly. Supercow's powers lie in a green blanket and her outfit is purple with a logo on the chest which resembles that of Superman. Her alter ego Supercow speaks Spanish, and in several episodes exclaims: "¡Supercow al rescate!" ("Supercow to the rescue!") (in the Spanish edition of the show, she speaks the catch phrase in English). Cow first became Supercow in the Pilot, "No Smoking."
Cow is a yellow cow with brown spots. She has dark grey hoofs, light salmon colored udder/butt/snout and has two tiny brown horns.
A superheroine with superhuman strength, near-invulnerability, and the ability to fly.
Supercow's powers lie in a green blanket that she wears as a cape, and her costume is purple with a logo on the chest which slightly resembles that of Superman, but with a C instead of a S.
Inexplicably, she speaks Spanish. Her catchphrase is "¡Supercow al rescate!" ("Supercow to the rescue!") (in the Spanish edition of the show, she speaks the catch phrase in English).
Cow first became Supercow in the Pilot, "No Smoking", where she had to rescue Chicken from Red Guy and Cerebus.
SuperCow also happens to don a tricycle in some episodes, i.e Field Trip to Folsom Prison, where she replaces Chicken with the real red.
