Dib

"My heads not big!"

- Dib

Dib Membrane is an eccentric young boy who is obsessed with the paranormal. He is the brother of Gaz and

the son of Professor Membrane, as well as Zim's greatest nemesis. He attends schoolwith Zim, and is determined to stop him from conquering Earth and expose him as an alien, though almost nobody believes him. He is highly unpopular at school and at home for said obsession with the paranormal, and is often dismissed as "crazy" or "insane."

In Issue #0 of the Invader Zim comic "TruthShrieker", it is confirmed that Dib's (and Gaz's) last name is "Membrane". He is the author of an article about Zim's mysterious dissapearance and the article is by "Dib Membrane".

Dib is 11-13 Earth years

old (during seasons 1-3) and resembles his father [Membrane|Professor Membrane]. Both have black, scythe-like hair; in Dib's Wonderful Life of Doom Dib's got more jagged and bigger with age. Many people claim that Dib's head is big, a running gag in the show; but it's not visibly bigger. The redesign process [Save the Dib|God Save the Dib], however, actually gave him a bigger head.

His hair spike seems to be solid, and retains its shape even when getting wet. It took a water balloon of ridiculous proportions dropped from Earth's orbit and a second normal water balloon in order to get it to bend, as seen in [Wettening|The Wettening]. Dib seems to be able to zip-line with his hair spike (using the spike as the runners), as seen in [Drivers From Beyond the Stars|Backseat Drivers From Beyond the Stars]. Likewise, it seems solid enough to punch through a brick wall like any part of his body if Dib is flung hard enough, as seen in [der Soulstealer|Mortos der Soulstealer].

He wears a pair of round glasses and a trademark black trench coat along with a blue shirt with an unsmiling grey face on it, pulled directly from Squee!, in which the main character, Todd, also known as Squee, wears exactly the same shirt.
