History
Edit
Mrs. O'Leary was originally Quintus' hellhound pet. Quintus tamed her and they became very close. She is faithful to Quintus, then to Percy. According to Quintus, the story of how he got her involves "many close calls with death and quite a few giant squeaky toys."
Percy Jackson and the OlympiansEdit
The Battle of the LabyrinthEdit
Mrs. O'Leary comes to Camp Half-Blood with her owner Quintus. When Percy first sees her, he attacks her but is stopped by Quintus who wouldn't let anything happen to his pet. Mrs. O'Leary turns out not to be violent, but a very sweet and friendly, making friends with Percy and Tyson, and often playing with a shield as a Frisbee and a combat dummy to play fetch. When Percy is about to journey into the labyrinth, Quintus gives him a 
Added by Nafisa.t13In Antaeus' Arena, Percy used the whistle to call Mrs. O'Leary for help to save himself, Annabeth Chase, Rachel Elizabeth Dare and Ethan Nakamura, but she disappeared after they fled from Luke Castellan's minions. Mrs. O'Leary found her way back to Quintus, who was revealed to be Daedalus who had originally built the labyrinth. When they were attacked by Luke's monsters, Percy and his friends fled, but Quintus wouldn't leave his pet. They made it out and joined the Battle of the Labyrinth at camp. With the help of Nico di Angelo, son of Hades, Daedalus passed on and left Mrs. O'Leary in Percy's care.
When Percy left camp, he left Mrs. O'Leary in the care of Charles Beckendorf who forged her a collar, a toy and other useful items.
The Demigod FilesEdit
The Sword of HadesEdit
Mrs. O'Leary arrives in the middle of Percy's English exams and the mist makes everyone believe she was a poodle, which impressed Percy due to her size. He follows her into the park where he comes across Thalia Grace and Nico who, along with Percy, were all taken to the Underworld. Mrs. O'Leary tries to warn him, but she was too late.
The Last OlympianEdit
Percy is ambushed by a gleeful Mrs. O'Leary who is happy to see him at camp. Percy becomes sad as he remembers how Beckendorf (who died a few hours ago on the Princess Andromeda) would take care of her when Percy would be away for a quest or vacations. Beckendorf had also welded Mrs. O'Leary's favorite bronze chewing bone, and her collar. Pushing the sad thought away, Percy follows her until he found Nico with Juniper and Leneus. Nico takes the hellhound for a walk while the others talk because Juniper and Leneus were both afraid of dogs. Nico gets Percy to leave with him afterwards to Luke's mother's house. Percy rides on Mrs. O'Leary who uses shadow travel which tires her. After the meeting, they met Hestia who gives Mrs. O'Leary a large dog treat. Due to shadow traveling, the huge hellhound yawns and takes a nap.
Added by Fan'o'stuffWith the help of Grover, they are able to get to the Underworld where Mrs. O'Leary makes friends with Cerberus. Percy calls her off when the Furies came to collect them. After Percy and Nico escape, she transports them to the River Styx where Percy baths to receive the Curse of Achilles.
Mrs. O'Leary takes part in the Second Olympian War, but got injured fighting the Drakon. She gets a message from Percy to Nico for reinforcements and takes an injured Chiron back to camp.
During the war, Percy had to face a hellhound, but hesitated to kill it. He reminded himself: "This is not Mrs. O'Leary. This is an untamed monster. It will kill me and all my friends."
The Heroes of OlympusEdit
The Son of NeptuneEdit
In one of his dreams, Percy sees Tyson riding her as they look for him. Percy then whistles for her when he and his friends are right near Camp Jupiter and she helps them haul tons of Imperial Gold and fights in the battle, and attacks a Gorgon. Once the battle is over, Percy watches her play with Hannibal and says how she has finally found a play mate who she can rough-house with.
The Mark of AthenaEdit
Mrs. O' Leary is first seen among the mob in New Rome, carrying Tyson into the city. She later enters the Forum, while Ella rests on her back. After Ella's sudden outburst, Percy tells Tyson to take Mrs. O' Leary and Ella someplace else and they leave by shadow traveling away. Percy later informs his companions that he told Tyson to take Ella to Camp Half-Blood. Chiron then informs the group that Ella, Tyson, and Mrs. O' Leary had arrived safely.
AppearanceEdit
Mrs. O'Leary is very large, very scary and described as a mastiff. Percy describes her as "bigger than a tank and barks slightly louder than an artillery gun". Mortals, on at least one occasion, see her as a large standard poodle, rather than an impossibly big dog. That fact truly shows how powerful the Mist is.
AbilitiesEdit
- Shadow Travel - Like all hellhounds, Mrs. O'Leary can shadow travel, though this is shown to tire her.
- Immortality - Like all monsters, Mrs. O'Leary cannot die. She will just be reborn from Tartarus, like any other monster, unless killed by Stygian Iron. Whether her personality and friendliness would be affected by this is unknown.
TriviaEdit
- Mrs. O'Leary is the only known hellhound to be friendly.
- When Daedalus is asked how he got a hellhound for a pet, he told Percy it was a long story that involved a lot of close calls with death and quite a few giant squeaky toys. When Hazel Levesque questioned Percy about having a hellhound for a pet, Percy told her it was a long story just like Daedalus told him. Percy's story also involved a lot of close calls with death and a few giant chew toys.
