Phil Ken Sebben was the president of the law firm Sebben & Sebben in Harvey Birdman: Attorney at Law, taking the role of Harvey's boss. Although the character in the original series was a Inter-Nation Security agent, in Harvey Birdman, he is portrayed as an unscrupulous businessman who likes to stalk his employees and enslave ancient civilizations like the cavemen.
He was voiced by Stephen Colbert in Harvey Birdman and Stephen Stanton in the videogame.
History
Harvey Birdman, Attorney at Law
Sometimes he's helpful and sometimes he's not. Other times he appears to be a traitor and was once charged for driving dangerously and running over pedestrians day after day. However, later he is declared innocent but only because of Harvey's skills at the tribunal and the fact that judge Mentok the Mindtaker apparently didn't really care about the case.
In another episode he shows signs of insanity and paranoia and abuses his employees by installing cameras on every corner of the building (even the restrooms) and constantly spying on them and reading their e-mails. Phil once gave Harvey's title to Blue Falcon and Dyno-Mutt. He once tried to marry his own daughter's secret alter-ego Birdgirl; although to be fair to him he was unaware of her real identity and too gullible to accept it even when Harvey told him that (he assumed Harvey was lying).
Harvey Birdman: Attorney General
At some point, Phil became the 46.5th president of the United States.
Birdgirl
After Phil's death, his daughter Judy/Birdgirl, became new president of Sebben & Sebben.
