Nurse Ratched – The ward superintendent and ultimate authority.
A handsome woman in her late forties/early fifties with an odd perfection about
her -- a face smooth, calculated, and precision-made, like an expensive baby
doll.
Chief Bromden - A large, bull-muscled Native American with
schizophrenia. While he is a powerful man of six and a half feet, he thinks of
himself as small. Through most of the action he pretends to be deaf and dumb.

adolescent still under his mother’s control. Billy has an extreme speech
impediment (stutter).
Dale Harding – Age: 40 – 50, The most educated of the patients and their unofficial leader
before McMurphy's arrival; a handsome, nervous effete man.

an "Acute" patient, now a "Chronic" in a vegetative state,
the result of electroshock therapy.

cavalry soldier who cannot move without a wheelchair. He is given to lifting
the skirts of passing nurses or teaching history out of the text of his left
hand.
Jim Sefelt –
Age: 40, An
epileptic patient. He refuses to take his anti-seizure medication because he is
afraid that his hair and teeth will fall out.

no great force.

to be capable of performing Nurse Ratched's bidding with precision
