Catch-22

Main Characters and Their Development

• John Yossarian - a U.S. bombardier lieutenant who becomes paranoid and obsessively seeks to survive, attempting to avoid flight missions under the pretext of his own madness.
• Chaplain Tappman - an army chaplain who transforms throughout the novel from an insecure and shy man into a determined supporter of Yossarian.
• Milo Minderbinder - an entrepreneur and unscrupulous trader, head of the M&M Syndicate, who values profit over the lives of pilots and even does business with the enemy.
• Doc Daneeka - a squadron doctor initially indifferent to Yossarian and other soldiers, whose attitude changes as the plot develops, confronting the absurdity of military bureaucracy.
