Pi

Perry "Pi" McDonald is Harvey Kinkle's best friend and the resident wacky inventor/conspiracy theorist.

History

He is very smart and quite unusual in his own special way. His eyes are never seen because his pork pie hat obscures them. He has been described by Sabrina as "totally out of it and really smart at the same time."

Pi is visibly petite compared to the other preteens and has long hair. This, coupled with his high, though raspy, voice gives him a very feminine demeanor. He dresses in a vintage spy style outfit complete with a fedora that covers his eyes. He is stated to be Chinese.

Pi is obsessed with the paranormal and will chase it to the ends of the earth, he is also a genius and is capable of building interesting gadgets such as a snow machine and a cold fusion reactor (with Harvey's help)

He is the least liked in the group and Sabrina and Chloe often brush him off as an annoyance

He has been more involved in the plot than his usual role as a minor character in the episodes, Strange New World, Paranormal Pi (during which he was the focus) and Hexcalibur (playing the part of Merlin). During his time in the spotlight it's hinted that he may suffer from a superiority complex, low self esteem and abandonment issues, as is evident with his tendency to become very upset and sad when things don't work out and everyone's willingness to abandon him.

Of all the characters, Harvey and Pi are the closest and Harvey will often show protective tendencies towards his friend most prominent in Paranormal Pi and when he shielded him from the tornado in Witchitis. Pi, in return, is very attached to Harvey and becomes distressed if their friendship if threatened or Harvey refuses to believe him.
