dib

Dib is separated from the rest of his peers by his exceptional intelligence and determination. Also, Dib continues to seek out the paranormal despite the considerable ridicule he receives from both peers and family.

He considers himself to be the sole defender of Earth against Zim's plans of conquest, and rightly so; he's in fact the only one who knows (or cares) that Zim is an Irken Invader bent on world destruction.

When Zim first landed on Earth, Dib was initially shown to be more antagonistic, obsessed, and desperate, making it his sole goal in life to expose Zim as an alien by any means necessary.

However, he eventually realized that any efforts to reveal Zim would be wasted on his oblivious and mean spirited peers, and Dib eventually lost his obsessive, desperate edge, becoming a more humorous, depressive and more sympathetic character overall. His hatred of Zim eventually becomes real as the Irken takes every opportunity to make his existence even more miserable than it already it is even when unprovoked, making Dib's efforts to beat Zim all the more personal.

Dib shares his father's scientific and technological prowess, with skills that far exceed the average human being. He has been known to created advanced technology entirely from scratch (for example, an advanced water balloon-launching apparatus).

These skills aren't limited to just Earth-based technology, either. Dib has on multiple occasions proven a keen understanding of Irken technology as well, whether it be hacking into Zim's base, reverse-engineering a rogue Invader's crashed vessel, or remotely flying the Irken flagship itself.
