You clown! He's here to take over our minds! Even yours.
~ Kipple to Grawl.
Professor Kipple is the secondary/true main antagonist of the 2009 3D computer-animated film, Planet 51, and unlike the misguided General Grawl, Professor Kipple did not redeem himself by the end of the film.


Although he passed himself off as a scientist in reality Professor Kipple was a fake and loved to experiment on others via literally removing their brains - this was not fatal but did cause his victims to become quite mad: he became quite obsessed himself with getting his hands on the brain of the "alien" that had arrived on the planet (who was in reality an astronaut from Earth).


  • He is voiced by John Cleese.
