Perseus Iroas

Perseus Alexander Iroas (who goes by "Percy" at most times) is a sixteen-year-old Rhesus Macaque monkey who attends Newshore High School with "Cookie's Monsters" protagonist, Cookie Souris. He is the son of Judas Iroas, and works in his occult magic store, Jude's Occult, part-time in Beach City, where he also lives. He is one of the first few characters introduced in the series, and is largely considered to be Cookie's sidekick.

He is, among other things, a notorious flirt. He is often, if not always seen flirting with female characters, and even Cookie to some extent despite her intermixed gender. Despite this, and his generally carefree attitude, he is more often than not a helpful ally in Cookie's magic-related endeavours.

Background
Perseus moved to Beach City with his father, Judas Iroas, in the summer before the first "Cookie's Monsters" story.

Boo Hag
Perseus was first introduced in "Cookie's Monsters - Boo Hag" where he happened upon Cookie Souris after a Third Eye vision episode ended with her in the school nurse's office. Perseus was simply there faking illness so he could spend more time with the nurse, who he thought was attractive for an older woman. Despite coming off as initially undesirable as an acquaintance, he helps Cookie along in uncovering the mystery of the Boo Hag.

With Perseus' help (both direct and indirect), Cookie survives when the Boo Hags lead her out to an old cabin in an attempt on her life. After this, Perseus seems insistent on spending more time with her and learning more about the monsters and her magical capabilities. He is present when Cookie finally dispatches the Boo Hags once and for all, playing a minimal role in doing so.

Ghost Boyfriend
When it became apparent that Simon Oliver had been possessed by the ghost of Anthony Peter Shultz, Percy jumped into action to protect Cookie from him, and then to catch and restrain the runaway Simon. Once Simon was safe in Cookie's care, Percy began looking through the old books in his father's occult shop for any details about ghosts and exorcisms.

While he wasn't able to learn anything helpful that Sidney hadn't already shared, Percy did learn how to make Ghost Dust, and did so for Cookie's final confrontation with Anthony. He joined her in the task, physically restraining the supernaturally-strong Simon long enough for Cookie to perform an exorcism and banish the ghost of Anthony back to the Nevernever.

Appearance
Percy is consistently described in the stories as being tall and lanky, with long arms and legs. He has dark hair with a slightly blue tint and hazel eyes. His fur is a light tan, almost golden colour, and the exposed skin of his face, hands, feet and chest is tanned. Cookie often comments in narrative that his eyebrows are rather thick, and his facial hair is trimmed into thick sideburns connected by a thinner beard.

Being an athlete, Percy's body reflects his active lifestyle. He has a toned musculature for his slender physique.
