Charlie is a nonchalant and laid-back critter with a rational and calm, albeit slightly pessimistic, outlook on life. He typically speaks in a monotone voice, only raising it in moments of fear, panic, surprise, or pain. Often acting as the straight man, he encourages others to calm down in an indifferent manner. Despite his usually composed demeanor, Charlie sees himself as an 'alpha male' and sometimes escalates situations by attempting to take control, as seen when he tries to wrestle a gun.
