Percy is good looking, with red hair and pale skin from the many hours he spends inside reading. He is gangly and awkward, and wears spectacles. Inexplicably, he is attractive to debutantes.
Quesnel Lefoux calls him "Pompous Percy." Percy hates that he is inexplicably attractive to debutants, so he hides indoors and his only interest is in books. He is a good strategist and technician, good at coming up with redundancies and backup plans.
As soon as Percy came of age, he moved out of his mother's hive and accepted a post as an Oxford don. His time at Oxford didn't last; he was dismissed for radical theories on the transcendental sprout-shaped nature of the aetherosphere. Afterwards, he moved into a home behind the British Museum, off Russell Square.
In the booksEdit
In Timeless, Percy travels with his family to Egypt, along with the Maccons. His sister Primrose is mistaken for Prudence and kidnapped by the Alexandria Hive. She is later rescued by the adults of both families, and escapes unharmed, though their mother is fatally wounded in the attempt and is metamorphosed into a vampire queen while there.
At the beginning of Imprudence, Rue, Primrose and Virgil are worried because Percy had taken off in a huff. They discover him in the library aboard the Spotted Custard in a near-rage over a paper Quesnel had done, but refusing to talk about it. Quesnel had published a story in the Royal Society with Mrs. Featherstonehaugh about the weremonkies before Percy, which is why Percy was so upset. In retaliation he published his own paper on the werecats. When this fact is discovered while the crew is in Egypt, it leads Rue to believe the attacks on the ship have been an effort to capture Tasherit. Percy becomes very contrite and does his best to make up for his bad behavior.

- “The Rakshasa,' said Percy pedantically, 'are a different breed altogether from our vampires. Much in the same way that poodles and dachshunds are different breeds of dog. Rakshasas are reviled in India. Their position as tax collectors is an attempt by the crown to integrate them in a more progressive and mundane manner. Rue said, 'Oh, how logical. Because we all know ordaining someone as a tax collector is the surest way to get them accepted by society.” (Prudence, Chapter Nine)
