Quincy Membrane

"That's Quincy Membrane. He's a prof. A professor. Now he's approving that Dib and Zim are now forgiven. I also appprove this too. That's damn straight."

--Su Ji-Hoon, Forgiveness

Professor Quincy Membrane is the father of Dib and Gaz, but he has very little time for his offspring, being one of the most famous and important people on Earth. Professor Quincy, as he is often called, is rarely at home, so he supervises his kids in the form of a floating monitor, which often spews out pre-recorded reminders that are often way out-of-date. Expectedly, Dib and Gaz refer to him as Dad.
