Guy Montag, our main character, is a thirty-year-old fireman who takes pride and pleasure in what he does. He is married, people fear and respect him, and he thinks himself happy. However, after acquiring a friendship with the new neighbor Clarisse McClellan, Montag realizes he is not happy at all. He begins to question everything he was once so sure of. He realizes that there is nothing wrong with books. The problem lies in not reading the books, because all the citizens are ignorant without opinions or feelings of thier own. Three character traits of his that come into play is his courageousness, inquisitiveness, and rebelliousness. With these three traits, Guy Montag starts a journey that will lead him away from his corrupted to society, and on to true happiness.
Mildred Montag is the wife of our main character Guy Montag. Her personality is the shallow complacent personality that Guy Montag comes to loathe. She, like the rest of this modernized society, surrounds herself with new-age technology in attempt to escape from reality. Always following the crowd, never protesting, never objecting to what society has become, Mildred becomes that which her husband is protesting: mindless. All Mildred wants is to be happy, and she has let herself become content spending all her days viewing and agreeing with television. She doesn't want chaos and conflict to ruin her life, but she ruins it anyway by letting herself become trapped in a false happiness, and it is this false happiness along with her personality that drove her to leave her husband and her home, leading her to her doom.
Clarisse McClellan is a seventeen-year-old girl that Guy Montag has taken a liking to. She is very curious and aware of the world around her. While many other children her age are watching "the family" in the parlor, or going to races and Fun Parks, Clarisse does none of this. Therefore, she has time to 'stop and smell the roses'. She questions things others would disregard, and it is this trait that draws the attention of Guy Montag. Her awareness and way of thinking brings many things to the attention of Guy. It is her who starts him on his path to self-discovery and an attempt at world transformation.
Beatty is the Captain of the fireman. He has read books and knows what they are about, yet he continues his job and burns all books. I do not believe that Beatty agreed with books being illegal, but he did not have a strong enough personality to object to it. Everything was just so much easier if you followed the rules and never objected, never opposed what was said unto you. It was so much simpler for Beatty to just follow orders like an obedient dog. When the government told him to sit, he sat. When they said burn, he burned. Burning books was, for him, a straightforward taks that kept people happy by ridding the world of controversy. He knew this was wrong, but he did not have the will nor the courage to take a stand, which is why when he saw that Guy was willing to do something about it, he felt shame that he did nothing, and resolved to stop Guy instead of help him. Beatty made a lot of wrong decisions, and he knew this, which is why he wanted to die. He let himself do so at the hands of Guy Montag.
One of the few people left who still believe in books, Faber is a retired English Professor. It is he who Guy turns to when he realizes that he wants to make a change. Faber knows what is right and wrong, what should and shouldn't be. However, too afraid of death and losing what little books he has left, Faber does nothing. The majority of the world does nothing, but in Faber's case, its different. Others don't know its wrong, but Faber does yet he does not act. Faber will never forgive himself for his cowardice, but when he has a chance to set things right, he does all he can to help and encourage Guy. Faber in this story is a "good guy", but, like Beatty, lacks the strong, defiant personality that is necessary to revolutionize the world.
Not human, but not lifeless, the Mechanical Hound is a unique character in this story. The Mechanical Hound is just that: a mechanical hound. It is not real, but somehow it has been given life. The creators give it a tiny amount of "personality," but its main purpose is to attack. It is given a target and will not rest until the target has been extinguished. The Mechanical Hound proved itself worthy when, towards the end of the book, the entire city was hunting Guy Montag. The Hound made a spectacular appearance at the moment he found who everyone assumed to be Guy Montag. It used every attacking move he was programmed to use down to the very moment of his victim's death.
