Professor Parenthesis

Professor Parenthesis is the main antagonist of the Phineas and Ferb television episode "O.W.C.A. Files". He's an evil flea scientist bent on taking over O.W.C.A. with his own army of Mecha-Fleas to take control of all of O.W.C.A.'s agents to do his bidding for him. Unlike most evil-doers who are dealt with by the agents, he is clearly a more intelligent and dangerous villain, always putting on a few tricks up his sleeve.
He has a habit of mispronouncing words by putting emphasis on the wrong syllables.
==Physical appearance==
In his usual human appearance, Parenthesis has tan skin, blue eyes, and light yellow hair pointing upon his forehead. His head resembles that of a round bracket, hence his name. He wears a white lab coat with two light-green shoulder pads, green shorts, and pink slippers.
However, this appearance was nothing more than an android to conceal his true appearance: that of a tiny blue four-armed flea wearing a white shirt and pink slippers. Parenthesis' android is also capable of procuring four mechanical tentacles as back-up weapons and a giant LCD screen to show his true face to his enemies.
==Role in the episode==
He first appeared as a hologram and reveal he went to school with Francis Monogram but was unnoticed by him. After Monogram tries to recall him, Parenthesis explains he spent years planning his revenge. He sent a box of flea collars to O.W.C.A. headquarters secretly filled with robot fleas that would give him full control over all the animal agents. With the building on lockdown, Monogram sends a message to Perry the Platypus and his team of new recruits, including Doofenshmirtz, and they soon discover the box for the flea collars and the return address was the bottom of the Grand Canyon.
After arriving at the canyon, Parenthesis learns they were coming and has his robots fleas attack them. The group, minus Doof who is asked to stay behind by Perry, then infiltrates Parenthesis' hideout but are easily captured. He then informs them that soon his robots fleas will make his control over the O.W.C.A. agents permanent and leaves for the HQ with several of his robots. Doof soon arrives and frees the group, but the base is destroyed in the process. Parenthesis and his robots arrive at O.W.C.A. HQ and reveals he plans to sick the agents on the world. At that moment, Perry arrives, after seemingly abandoning the others at the Grand Canyon, and kicks off Parenthesis' head, revealing himself to be a robot. Shortly afterwards, robotic tentacles emerge from the robot and reveal that Parenthesis is actually a flea himself. He then subdues Monogram and Carl and chases after Perry with his robots through an obstacle course. After arriving at a carnival caper simulation, Perry team shows up, revealing Perry left a message for them into a training book to meet him there, but Parenthesis captures them. However, Karen the cat destroys his robots and frees the others. Parenthesis is still confident as his control over the agents was almost permanent, but a fan, that was being used by Napoleon, Wendall, and Floyd, falls on him and drops the remote, breaking it and freeing the agents. Parenthesis is then captured and Perry's team become official agents.
