Barnabus Sidebottom

"Glowering at me behind the world's most horrendous hairpiece. It looked like a raccoon had died on his head. And then been run over by a truck."

- Benjamin Ripley describing the principal's toupee in Spy Ski School

Barnabus Sidebottom is the principal of the CIA Academy of Espionage, although, for being an employee of an intelligence agency, he doesn't often display much intelligence. Sidebottom also holds a large grudge against Ben. Ben inadvertently blew up his office in Evil Spy School, and even though it wasn't Ben's fault, the principal still held him responsible and was happy to expel him. In Spy Ski School, he seemed almost pleased with the possibility of Ben dying in a mission.

Backstory
Sidebottom had been in the field before, but he was a very bad spy: foiled every single mission and was caught on several occasions. He was even tortured once on a mission. As a result, he was given the job of being the principal of the CIA Academy, since nobody else wanted to do the tedious paperwork.

Appearance & Personality
The principal is a large, stocky, middle-aged man. He is bald but wears a wig, which isn't always the best looking. When he was first described in Spy School, he had food stains on his suit. He is quite irascible where Ben is concerned, and his face almost changes colors when he gets furious. He also has a tic which is a twitch in his left eye.

Skills & Inabilities
The principal has been shown to be very incompetent on several occasions. In Spy Ski School, he attempts to use the PA system to call Ben to his office, but has a hard time figuring out how to turn it on and use it. During a relatively important trial in Spy School Secret Service, the principal keeps playing a mobile game called Flapjack Frenzy. He is not good at remembering codes. The password to the principal's office was once "12345678."

Trivia

 * Zoe's nickname for him is "The Idiot."
 * One of his toupees got shot off by Murray Hill (with a dummy bullet) during his final combat simulation.
 * Another of his toupees got fried when his office got blown up by a mortar in Evil Spy School.
 * After his office got destroyed, the principal had to transfer into a closet. The sign on the closet says "Pirncipal," indicating that it was written by the principal himself.
