Victory! Victory for Zim!
~ Zim

Invader Zim is the titular main protagonist (more of a protagonist villain) of the franchise of the same name. He is an Irken serving the Irken Empire as an Invader. Because of his incompetence, Zim was banished to Earth by the Almighty Tallests under the guise of being sent to conquer it.

Although he is the main character, Zim is morally (and ethically) a villain, being overall a fairly tendentious, argumentative, confrontational and unsympathetic character, though he occasionally shows some kindness towards certain characters. Nevertheless, he is prone to causing chaos and destruction for either himself, his own race, or Earth. However, in the pilot and first episode of the show, the main antagonist was Dib.

He was voiced by Richard Steven Horvitz, who also played Kaos in the Skylanders franchise, Zhencha in Disney's Mulan, and Lugosi in Bunnicula.


His skin is green, pink/red clothes, black gloves, pants, and shoes, a PAK on his back, and red eyes with two white pupils on each eye. The big pupil on an Irken eye was the main and the smallet pupil was connected to the main pupil.

Zim also has ruby-colored eyes; a very common trait in Irkens. It was also mentioned in Walk 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.



Zim is an Irken fellow born from Irk. When he was on O.I.D 1, he was assigning to Blorch, but accidentally used Irk as a target and ended up banned to Foodcourtia. After days passed, he later escaped and goes on O.I.D 2, where the Tallest fooled him that there was a secret planet that is mysterious, and never known what it was. Accompanying him on his exile mission was his robot assistant GIR.

Zim was sent into exile by the Almighty Tallests due to Zim accidentally almost destroying Irk with a massive robot assault walker destroying entire buildings and military vehicles in his path and possibly killing dozens of other Irkens and ruining Operation Impending Doom (OID 1 for short) for not knowing that he was attacking the wrong planet. As punishment, Zim was sent into exile and was sent to Food Courtia as punishment for almost toppling the Irken Empire. During the Great Assigning for Operation Impending Doom ll, Zim escaped and made it to Irk where he expected to be given an assigned planet but instead was given a sandwich and was told to leave. In response to his refusal to leave, Zim was sent to Earth unaware that the Tallests thought it was fake and was given GIR, a SIR unit (Self Information Retrieval Unti) made from garbage and other junk that was defected from the others.
