Zim

"I am ZIM!!"

- Zim on many different occasions

Invader Zim is the titular protagonist and anti-hero of the series by the same name.

Zim is a member of the alien Irken race, and a former Irken Invader; however, since his actions usually lead to disaster (having nearly destroyed the Irken homeworld during Operation Impending Doom I) his leaders, the Almighty Tallest, banished him to Foodcourtia. While there, however, Zim heard of Operation Impending Doom II, and - obviously not understanding the purpose of his previous exile - "quit being banished" and ventured to Conventia in the hope of getting an assignment. Chagrined, the Almighty Tallest sent him on a "secret mission" to Earth, in order to keep him occupied and away from the real Operation Impending Doom II. After arriving on Earth, Zim enrolled in the nearest elementary skool to begin his infiltration and gather information about the indigenous race. There, he became quick rivals with Dib, an avid preteen paranormal investigator.

Zim's primary desire is to conquer Earth, mostly to prove his superiority and impress his leaders. However, as mentioned by Gaz in Bloaty's Pizza Hog, "He's so bad at it."

Although he is the protagonist, Zim is morally, and ethically a villain, being overall a fairly unsympathetic character, though he occasionally shows some kindness towards certain characters, (such as GIR in Walk of Doom), and is usually only causing chaos and destruction for either himself, his own race, or Earth. As well, almost everyone else he comes into contact with at any time. His unawareness of his destructive actions is most likely the result of him being a "defect", as revealed in the cancelled episode The Trial.

Zim's appearance, like that of most of the Irken race, seems to be based off the typical "little green men from outer space" stereotype. Many Irkens are about the size of a preteen schoolchild, but Zim is exceptionally short. In The Nightmare Begins, Zim was shown to be even shorter than the notoriously diminutive Skoodge.

Zim also has ruby-colored eyes; a very common trait in Irkens. It was also mentioned inWalk of Doom that Zim's eyes contain ocular implants. Since the eyes he was born with are not visibly different from subsequent appearances, it can be assumed that these implants are subcutaneous. As he considers himself to still be an Invader, he continues to wear the standard uniform: a red tunic-like garment with a pink collar and sleeves, as well as black boots and gloves.

He also possesses a pair of antennae; their exact function is unknown, but they seem to function like human eyebrows; rising and lowering to convey emotion. It is possible that they also function as an organ in place of ears, as they picked up vibrations in Battle of the Planets.

While most Irkens are expected to be ruthlessly loyal to the Empire, Zim is considered overzealous even by their standards: Brash, arrogant and overconfident, Zim's tendency to cause wanton destruction makes him a danger to himself and his own people, yet he still considers himself a mighty Irken warrior. In addition, he is acutely narcissistic and megalomaniacal, congratulating himself on even the smallest of successes; these, however, are rare.
