Dib Membrane

Dibert "Dib" Membrane (known as Fred in the French version) is the main antagonist of the animated sci-fi dark comedy television series Invader Zim, and the main protagonist of the 2019 Netflix film Enter the Florpus. Dib is a young, eccentric boy who possesses a fascination with unexplained paranormal phenomena, such as ghost hunting, Ufology, and cryptology, as well as with the supernatural and occult.
He intercepted the words spoken at the Great Assigning on planet Conventia in the first episode with his laptop. Six months later, he noticed a strange, green foreign exchange student enter his classroom. Dib tried his best to convince the world that it is in danger, but nobody believed him, due to previous erroneous claims of supernatural beings. Since then, he has made it his mission to protect his oblivious home from Zim's schemes against all odds.
He is voiced by .
==Appearance==
Dib is a 12 year old boy who resembles his father, Professor Membrane. Both have black hair. He wears a black trench coat, a blue shirt with a logo of a grey face and glasses. 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 God Save the Dib, however, actually gave him a bigger head.
==Personality==
As being separated by his peers, Dib spends seeking out the paranormal, with his exceptional intelligence and determination. He considers himself Earth's sole defender against Zim's evil plans to enslave humanity and knows that Zim is completely an alien from the Irken Empire. 
When Zim came to Earth, disguised as a normal boy, Dib was initially shown to be more antagonistic, obsessed, and desperate, making it his one and only primary goal to expose Zim as an alien by any means necessary. Every time Dib tries to reveal Zim's alien appearance to his peers it becomes a waste of his oblivious and they would think he's insane or crazy. 
After that, Dib would lose his obsessive, desperate edge and become a more humorous and depressive. Dib's hatred of Zim is completely real as Zim would take every opportunity to make his existence even more miserable than it is even when unprovoked, making Dib's efforts to beat Zim all the more personal than ever.
Dib is often hyperactive, and when Zim's blatant alien nature continues to be unnoticed by everyone from his classmates to his own father, he can fly into hysterics, either ranting or merely screaming incomprehensibly.
Interestingly, Dib built a solid rapport with Tak, due to intellects and shared hatred of Zim; albeit since Tak was another Irken in an actually convincing disguise, their friendship was essentially annulled, and may have been a deception from Tak - which emphasises her talents at subterfuge, since Dib is usually perceptive. This lead to a case of the few times when Dib is willing to cooperate with Zim, which achieves surprising effectiveness and better than either could normally do alone; despite their mutual disdain, they are compatible forces.
While Dib is usually earnest in his attempts to educate people, he can often drift into arrogance, with his intelligence making him feel entitled to condescend to his peers and passersby; an element of his condescension is also partly, if not sometimes wholly, due to frustration at the seeming willful ignorance of the general public about supernatural and alien hazards. Dib's pride also leads him to ignore input from others, such as his sister Gaz, whose smarts match - if not far exceed - his own; granted, part of his overlooking of Gaz is due to her typically aggressive indifference.
Dib is desperate for Professor Membrance, his father's, approval as a fellow man of science, however, since the Professor doesn't believe in the supernatural nor aliens, he sympathetically yet ignorantly dismisses his son's claims as symptoms of insanity, which drives Dib to sadness, anger, or mostly a sense of defeat.
==Role In The Series==
While he is technically the show's hero, he has shown to be a very antagonistic character, often doing mean things to other characters to reach his own personal goals (the most notable being that he once gave his own little sister a curse that made everything she ate taste like pork so he could see what it did to humans, although - not to detract from its unethics - he didn't know that's what the curse did) as well as doing crazy and often life threatening things just to stop Zim. He is also almost always stalking him. He has a sister named Gaz.
==Trivia==
*While Zim and Dib hate each other, they actually need each other. It is revealed in the cancelled episode, Mopiness of Doom, without Dib, Zim would lose interest in his mission and without Zim, Dib would get bored and cannot prove to the world that Zim is an alien.
*Dib is Jhonen Vasquez's favorite character in the show.
*Dib was a member of the Evil Syndicate (the main antagonists of Nicktoons: Unite, & Glob of Doom). This was only because Zim joined the heroes' team, as Zim is the protagonist of his show, though not its hero.
**On top of that, Dib was left floating in space at the end, even though he wasn't seen conspiring with the rest of the Syndicate.
*In the French version he is renamed Fred.
