Professor Membrane

"NOT SCIENTIFICALLY POSSIBLE!"

The Professor, 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supervises his kids in the form of a floating monitor, which often spews out pre-recorded reminders that are often way out-of-date.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, his kids Dib and Gaz refer to him as Dad.

Membrane is somewhat embarrassed of his son's belief in the paranormal, refusing to call it a "proper" branch of science. However, he believes Dib's obsession is just a phase (or as he speaks of it, "temporary insanity"), that Dib will eventually grow out of, and allows his son to do as he pleases to an extent.

He even understands that letting go of such of notions isn't easy, comparing it to how he once believed sharks and humans could be friends (which cost him both his arms). On occasion, Membrane is so preoccupied with work that he fails to recognize his own kids.

Professor Membrane has also had a grudge against Santa Claus ever since he was a child, on Christmas day, instead of giving him twelve cases of Uranium-238 as he'd asked, Santa gave him a present overflowing with socks.

Although his lack of parenting skills seem to be missing in action, he really does love his kids, taking time at least once a year for dinner together—and always remembering to activate the food monitor.

Professor Membrane's appearance has not developed much since he was a child, other than his increased height. He wears a white lab coat, purple gloves, and big black boots. His eyes are never clearly seen due to him wearing goggles. His son Dib looks a lot like his father, both sharing black hair styled in similar scythe-like shapes. But the Professor has been slightly redesigned, with more hair on the top of his head in addition to the scythe, as well as a thicker coat that makes him look thicker than he did. Also his gloves and boots are now larger, the gloves acting to cover the fact he now has cybernetic arms (with it being heavily implied that they were lost in a vicious shark attack when he was a child).
