Meg McCaffrey

Margaret "Meg" McCaffrey is a twelve-year-old demigod daughter of Demeter, living on her own in Hell's Kitchen, Manhattan. After Apollo had been forced to live as a mortal, Meg saves him from being mugged. When she learns that he needs to be a servant to somebody, in order to return to Olympus, she claims him.

Early Life
Not much is currently known about Meg's early life, only that she was born to the goddess Demeter and an unknown mortal man, and that the god-emperor Nero killed her mortal father when she was still very young, and proceeded to take in and raise Meg as his own daughter. Through his sophisticated manipulation over the years, Nero was able to manipulate Meg into believing that he and the fearsome malevolent Beast were two separate people.

The Hidden Oracle
Meg threw trash at two muggers while they were mugging the former god Apollo. The former god feels that they are being watched and takes her to Percy Jackson's apartment. Sally Jackson gives her spare clothes. Percy decides to drive them to Camp Half-Blood.

Nosoi follow them, forcing Percy to crash his car in an orchard. The trio tries to fight the nosoi. Meg unintentionally summons a peach karpoi to fight off the nosoi, who bit a nosos head off then proceeded on finishing the remaining nosoi, even if they tried to retreat. Meg named the karpoi "Peaches". Using the western border, which is said to be wilder than the eastern border because of the heavily enchanted hills and woods, Meg, Peaches and Apollo made their way to Camp Half-Blood. She swings from tree branches and cartwheels through the mud. Apollo starts to hear voices when they reached the woods, causing for him to collapse. Meg tried her best to reach Camp Half-Blood while bearing most of Apollo's weight and unknowingly talking to the trees to tell them to get out of the way. As soon as they reached the camp, Apollo passed out.

Will Solace mentioned that while Apollo is asleep, Meg poked Connor Stoll in the eyes and kicked Sherman Yang in the crotch.

Appearance
Meg was described by Apollo as "small and pudgy", with dark hair chopped in a "pageboy" style and black cat-eye glasses with rhinestones in the corners. When Apollo first met her, she was wearing red sneakers, yellow tights, and a green tank dress. He thought she was dressed like a traffic light. She wears a green tank dress, black leggings, and a pair of red sneakers, to which she's apparently attached. Her voice was described as nasal and bossy. She also wears two gold rings, which she can transform into two Imperial Gold siccae blades.

After being cleaned up and dressed in more appropriate clothes by Sally Jackson, Apollo realised that Meg was a shockingly pretty young girl, with her dark pageboy hair shining glossy from being brushed, her face round, and she had an elfish springtime aura that reminded him very much of dryads.

Abilities

 * Chlorokinesis: As a daughter of Demeter, Meg has absolute control over plants, manipulating them to a multitude of effects.
 * Plant Telekinesis: Meg is able to telekinetically manipulate fruits and vegetables, thus saving Apollo from two thugs.
 * Plant Sensitivity: Meg can sense the location of various plants with superhuman precision, as she was able to quickly detect the odor of a golden apple in the Labyrinth. She later claims to have the ability to "hear" trees growing.

Trivia

 * Much like Luke Castellan, Meg is revealed to be a double agent of the series' main antagonist (Kronos and Nero respectively) near the end of the first book in one of the Camp Half-Blood series (The Lightning Thief and The Hidden Oracle respectively), though it should be noted that unlike Luke, Meg was shown to be quite apologetic and hesitant when it came to her true allegiance.
 * Meg is the second demigod known to wear glasses, the first being Jason Grace.
