Dark and Troubled Past: Chauntecleer was a thief and criminal, scheming to murder his land's leaders after his mother was killed by a wolf. An encounter with God allowed for a pre-story Heel-Face Turn.
Driven to Suicide: He does this to destroy the parasitic, evil worms which entered his body and maddened him.
The Determinator: During his fight with Cockatrice. This trait resurfaces in The Book of Sorrows', but plays a darker role.
Due to the Dead: If one of his animals dies, Chauntecleer will do anything in his power to ensure a proper burial, especially for Mundo Cani and Lord Russel.
Dying as Yourself: Because he killed the worms inside him along with himself, Chauntecleer is able to spend a few last moments with Pertelote.
Good Is Not Nice: Although well-meaning, Chauntecleer is haughty, quick to insult others, and can occasionally be quite selfish.
My Greatest Failure: His abandonment of Mundo Cani just before the dog defeated Wyrm and saved the animals. This leads to the main conflict of the sequel, in which Chauntecleer becomes dangerously obsessed with setting things right.
Sanity Slippage: In The Book of Sorrows, Chauntcleer's quest to raise Mundo Cani and the effects of the worms feeding on Wyrm's corpse damage his mind and alienate him from his animals, even driving him to try and kill his loyal ally John Wesley Weasel.
Taking You with Me: Chauntecleer slashes himself open with Gaff and the Slasher to kill the evil worms inside him.
Vitriolic Best Buds: Type I with Mundo Cani, who he constantly abuses verbally (but who he secretly cares deeply for).
Well-Intentioned Extremist: After the war, Chauntecleer decides to resurrect Mundo Cani and kill Wyrm by finding a way into the earth. In the process, Ferric the coyote's wife and child are killed in a stampede.
Chauntecleer's Number Two, a dog who came to the Coop and was allowed in by Chauntecleer. He is very depressed and is often seen crying, but his loyalty is proven when he sacrifices himself to stop Wyrm.
Apologises a Lot: Berates himself for failing to save a Wild Turkey, when he successfully rescued the others. Also apologises for his nose, being in the way, and existing.
Heroic Self-Deprecation: See Apologises a Lot. Mundo Cani constantly insults himself and does not even mind being used as a doormat by Chauntecleer. Given that he is easily the most heroic character in the book, his low self-esteem is likely to cause a few Tear Jerker moments.
Chauntecleer's favorite hen and a refugee from Cockatrice's land. She is capable and intelligent, and cares deeply for him.
Broken Bird: A literal example. Pertelote endured sexual abuse from Cockatrice alongside all of her fellow hens, who eventually were killed. For a while she is worried about Chauntecleer, who looks almost exactly like her tormentor. She goes berserk when she first sees him, which is understandable given what she went through.
Closer to Earth: She tends to be more terse and practical than Chauntecleer.
Dark and Troubled Past: Pertelote once lived across the river, and was one of Senex's hens who was raped by Cockatrice. However, she kept her spirit by using a stone to break the Basilisk eggs in her body, and was one of the only hens to escape.
Music for Courage: Pertelote sings to calm down the animals who are terrified of Cockatrice and the basilisks.
Plucky Girl: After being raped by Cockatrice, Pertelote uses a stone to break the Basilisk eggs in her body before they hatch. She can also hold her own in a fight, too, although Chauntecleer wasn't trying to harm her.
Women Are Wiser: Pertelote plays an important role in keeping the excitable Chauntecleer calm when he needs it.
John Wesley Weasel
A weasel and former thief who befriends the Wee Widow Mouse. He becomes one of Chauntecleer's best warriors, and has a special advantage against Basilisks.
Anti-Hero: Type III. He is significantly more ruthless when fighting than most of the other animals and is quick to call for the execution of Ebenezer Rat, but is without question on the heroes' side and is very protective of anyone he cares about.
One-Man Army: During the fight with the Basilisks, John Wesley's courage and badassery give the animals the strength to successfully drive the surviving Basilisks into the river, not to mention the several hundred that he kills himself.
Roaring Rampage of Revenge: John Wesley Weasel viciously attacks the Basilisks to avenge the Widow's death. He kills so many that Cockatrice intervenes directly to stop him from completely wiping them out.
Undying Loyalty: When the animals are afraid that Chauntecleer abandoned them to save himself, John Wesley Weasel is the only one who refuses to believe this. This carries over to the sequel, when Chauntecleer goes insane and tries to kill him.
Unstoppable Rage: After the Wee Widow Mouse's death, John Wesley Weasel becomes an unquestioned Badass, killing a slew of Basilisks on his own. Despite injuries. With one ear missing.
Wicked Weasel: Averted with him. Despite his ambiguous nature early in the book, John Wesley Weasel proves to be one of the good guys, and is disgusted by cowardice.
The Wee Widow Mouse (and family)
Another refugee of Cockatrice's kingdom, whose husband was killed by the Basilisks. She moves into Ebenezer Rat's hole with her children and befriends John Wesley Weasel. She is killed by a Basilisk which got into the Coop.
A group of turkeys who are the stupidest animals in the Coop. They are well-meaning but pouty and very dim-witted, and all of them die before the final battle.
Big Eater: Ocellata eats a stripe of Mundo Cani's hair and some pebbles.
The Ditz: The turkeys as a group are this. For example, they throw a pout en masse in protest of Mundo Cani saving their lives. Their stupidity is to the extent that they aren't aware if one of their own dies.
The Load: Ocellata and the other turkeys pout during war preparations, and do not help at all.
Shoo Out the Clowns: The mass death of the Wild Turkeys shifts the mood of the book to very, very dark.
Stupid Good: The turkeys are friendly enough, but are too stupid to be aware of danger.
Too Dumb to Live: All of them, but special mention goes to Thuringer, who died while giving a Basilisk a friendly greeting.
Ungrateful Bastard: A mild example in Ocelatta, who is too stupid to realize that Mundo Cani saved him from certain death.
Chauntecleer and Pertelote's three sons. All of them are killed by the Basilisks.
A fox who is a good friend of Chauntecleer. He is extremely chatty, making him seem cleverer than he really is. He helps look after the Pins, and is indirectly responsible for their deaths. He later dies of illness in The Book of Sorrows.
Came Back Wrong: After his death of infection, Wyrm's evil essence briefly reanimates Russel as a zombie.
Carnivore Confusion: Despite the fact that Lord Russel is a fox, Chauntecleer is willing to leave his children alone with him. This has fatal results, although the killer is a Basilisk, not Russel.
Chekhov's Gun: Lord Russel discovers that rue means protection from Basilisks before the other characters do.
Cunning Like a Fox: Played with. While he isn't stupid, Lord Russel isn't as clever as he or the Pins think he is.
Due to the Dead: After Russel's death, Chauntecleer goes out of his way to ensure that the fox gets a proper burial, resorting to a Burial at Sea at Wyrmsmere when the corpse reanimates and has to be re-killed.
Sealed Evil in a Can: Wyrm was sealed inside the Earth by God to prevent him from destroying everything. He is held in by the natural goodness of the animals.
The Dragon and Wyrm's agent on Earth. Cockatrice was born when Wyrm tricked an old rooster named Senex into fathering its son. He murders his father before forcing the hens to produce an army of basilisks for him.
How the Mighty Have Fallen: During his Glory Days, Senex wasn't a bad ruler to his animals. Now that he is very old, he is balding and very miserable-looking. Even his hens make fun of him behind his back.
Unwitting Pawn: Wyrm takes advantage of Senex's despair and desire to preserve his name to trick him. Senex, for his part, is not really evil, more desperate and pathetic than anything else, and is unaware of Wyrm's true nature.
Kick the Dog: While sympathetic to the hens at first, Toad exposes Pertelote as breaking her eggs, and physically attacks her.
Punch Clock Villain: Toad is this at first, and his introduction to Cockatrice (as an egg) by Senex was involuntary. During his job, at least early on, he genuinely feels sorry for the hens and talks to them.
Walking Wasteland: The Basilisks wilt plants simply by touching them, and their bite is fatal almost instantly.
A coyote who lives in a canyon with his wife, Rachel, and his children, Benoni, Hopsacking and Twill. He knows about the existence of a hole which leads into the earth, which Chauntecleer believes will allow him to save Mundo Cani.
Forgiveness: He is able to forgive Chauntecleer for the deaths of his family.
The Messiah: It's Ferric's love that eventually helps to snap Chauntecleer out of his delirium and realize what his actions have done.
Unwitting Instigator of Doom: His arrival leads to Chauntecleer's paranoia intensifying and eventually the deaths of his wife and children when the rooster starts a stampede during an attempt to kill John Wesley Weasel.
Walking the Earth: Temporarily, to find food for his family. This is how he finds Chauntecleer's Coop.
The Bird With No Tongue
A bird who is only able to speak gibberish. A long time ago, she was tricked by Wyrm into drinking his essence, causing her to lose her voice and twisting her body.
