Invader Slacks is an Irken Invader, assigned to the planet Boodie Nen, home of the large nostril people. He wears a terrible disguise, which may be even worse than Zim's.

Invader Yoogli is one of the many Irken Invaders. However, seeing as he never had the chance to appear in a finished episode, this is the only thing that is currently known about him. He wears pink leggings instead of the normal black. His PAK has no spots on it, and his uniform is missing stripes. Yoogli was assigned to unknown planet.

Also known as Big Zim. His history is presumably similar to Zim's, including how he tracked an Irken distress signal to Pandora's Quadrangle, and got through a portal to end up in the Zimvoid. However, in a major difference, this Zim is a huge, heavily muscled brute. According to him, this is due to him focusing on increasing his strength over everything else. As number 100, he is a member of Zim Number 1's elite, able to reside in the Zimvoid's main tower and help to rule. (Overconfident)

Alternate universe copy of Zim. Brash, arrogant.

A SIR Unit is an Irken-built android, designed to function as a servant. Typically, SIR units are silver with red eyes, shoulders, and chestplates, with no visible mouth.

Your little loyal robot companion. [Invader Zim]

Invader Sneakyonfoota is an Irken Invader. Not much is known about him. Interestingly, his name is "Sneaky on foot" which might indicate that he is stealthy. He also has a single spot on his PAK, which is unusual, and has no stripes on his uniform. He also has a somewhat large sloped forehead. He is very tall. Sneakyonfoota was assigned to an unknown planet.

Invader Stink is one of the many Irken Invaders who were assigned to the task of infiltrating enemy planets during Operation Impending Doom II. The tips of his antennae point forwards instead of backwards like most male Irkens, and he is one of multiple invaders without stripes on his uniform. Stink was assigned to unknown spotted planet with one moon.

The Alien Bees are human-sized flying insects that appeared in Invader Zim: Enter the Florpus.

This alien species resemble honey bees on Earth, except they don't have five eyes and instead have two Irken-like ones. They seem to live in hives in a moon-sized planet and are able to fly like all other bees seen in the show, with the exception that they only have two wings instead of four. (Art by furrik524)

Meet alien bees! [Invader Zim: Enter the Florpus]

Invader Skoo is an Irken Invader. His name is very similar to the name Skoodge, another Invader, and the name Spoo, one of Zim's classmates.

Skoo made only two appearances in the series, both cameos. He was first seen waiting for his turn during "The Great Assigning" in "The Nightmare Begins", and in "Battle of the Planets" he was seen clapping unenthusiastically after hearing that Skoodge was the Invader responsible for conquering Blorch.

Invader Kim is an Irken Invader. He made his debut in "The Nightmare Begins". He is also one of the few Invaders without any spots on their PAK, and one of the many without stripes on their uniform. Kim was assigned to unknown planet.

Invader Nen is an Irken Invader who was assigned to an unknown enemy planet. He is short with a fairly large head, and two small, circular eyes. There are no stripes on his uniform, or spots on his PAK. His most notable features are his crooked antennae, which seem to be a trait unique to him.

He also wears pink tights instead of the normal black ones, and boots that are a bit large for his feet. Nen was assigned to an unknown planet.

Blob creature that was created by Zim to crush the humanity and conquer the Earth for Zim, but after long time changed its mind about conquest; it restores human civilization and flied off into space to find other people to help. Kind, brave, friendly, empathic, cute. It looks like red blob in height of 5-7 meters with yellow eyes. Friendly, but alone.

Chill at irken lounge zone with other irkens!

Very little is known about this character aside from his minor appearance in "Walk for Your Lives", in which he proved to be well prepared for Probing Day. His tights are pink instead of the standard black, he has a stripeless shirt and spotless PAK.

Foodcourtia is one of many planets under the control of the Irken Empire. It's likely that Foodcourtia is the name given to this planet by the Irkens rather than the original title.

In the tradition of Irken efficiency, the planet was assigned a very specific purpose; in this case, to serve as an intergalactic food court.

Have a meal on food-court planet! [Invader Zim]

Planet Dirt is a garbage dump planet. Very little is known about it, but, unsurprisingly from the one scene in which it is shown in "Tak: The Hideous New Girl", its surface is littered with filth and garbage, hence the name.

Become a member of janitorial squad. [Invader Zim]

Invader Sklud is an Irken Invader who has assigned to an unknown enemy planet. His antennae bend forward of the usual backward, which seems to be very rare in Irkens.

Not to be confused with Captain Lard Nar, a Vortian who leads The Resisty.

Invader Lardnar was seen arriving on Conventia right before the beginning of The Great Assigning. His head is a somewhat unusual shape for an Irken. He has spots on his PAK, but no stripes on his uniform. Lardnar was assigned to unknown planet.

Invader Alexovich is an Irken invader named after character designer Aaron Alexovich. He appears to stand at a slight angle, and his eyes are more squat in shape than the standard Irken's. The color as well is somewhat different than most Invaders, almost coral pink.
Alexovich wears a standard Invader inform, minus the stripes. He has no visible ports on his PAK. 

He was assigned to an unknown planet. It is also unknown if he already conquered that planet or not.

Invader Krunk is an Irken Invader assigned to an unknown planet. He is squat and somewhat pudgy, with a thick neck and a very prominent lower jaw. These features imply that he has a case of underbite, which seems to be very common in Irkens.

Presumably due to a coloring error, Krunk is one of the few Invaders to have no spots on his PAK, and is missing stripes on his uniform.

Invader Chin is one of the tallest Irken Invaders in the Irken Empire. He is presumably named after the body part called a "chin".Chin is formidably tall and thin and wears the standard Invader uniform, excluding the stripes. His PAK appears very large, and has no spots on it at all, unlike most Irkens' PAKs. This is a recurring trait in many concept sketches. He is very tall and lean, unlike most other Irkens. Chin was assigned to an unknown planet. He's 5'10" something.

Devastis is a planet conquered by Irken Empire. Irken soldiers are tested here; should they pass, they become a member of the Irken Elite.

Pass the test and become invader! [Invader Zim]

A species of grub-like creatures, the Plim live on the planet of the same name, in a city by the same name. They were once an apparently very violent race, but all their advanced weaponry was sealed away in a massive vault, and a field was set up around their planet which makes it look barren and uninhabited from outside, while also disabling the electronics of any ship which tries to pass through it, thus leaving the Plim stranded.

Meet cute baby-like race. [Invader Zim comics]

Invader Dooky is an Irken invader, presumably named after dookie, a slang word for feces, which is commonly used throughout the series. Dooky is probably called this as he has round hazel eyes, an eye color rarely seen in Irkens. He has a short pair of antennae, and spots on his PAK, although no stripes on his shirt. Dooky is quite plump, much like Invaders Skoodge and Krunk. Dooky was assigned to an unknown planet.

Invader Flobee is an Irken Invader assigned to an unnamed planet which was inhabited by stupid looking creatures made from rock. Flobee, like most Invaders, had a rather silly disguise which consisted of rocks strapped to his body. When Zim spied on Flobee through his telescope, Flobee was taking a rest along with his SIR Unit, being hailed as the leader of the rock people.Flobee is one of multiple invaders without stripes on his uniform.

Invader Koot is an Irken Invader. He is rather short and squat, most likely around Skoodge's and Zim's height. He has unusually squashed red eyes and typical short antennae that flip backward. Like a multitude of other Invaders, his PAK has no spots, and his uniform has no stripes.

He was a blob-like "infinite energy-absorbing thingy" created by Zim while he was a scientist working on Planet Vort. Unfortunately, he ended up eating Tallest Miyuki, and later Tallest Spork when he came back to retrieve his collar.
(Also known as Infinite Energy Absorbing Blob)

Abandoned character from Invader Zim. Made by Zim.

Invader Yuli is one of the numerous Irken Invaders. She appeared briefly as a background character in the episode "Hobo 13", where she can be seen drinking soda and watching Zim's unexpected progress on the screen of the canteen she and her fellow invaders are gathered in. Yuli was assigned to an unknown planet.

The Slaughtering Rat People of Blorch are, as their name implies, a rat-like race that inhabited the planet Blorch. Their planet was conquered by Invader Skoodge.

This species makes their first appearance in "The Nightmare Begins" as a holographic image, depicting Rat People attacking Invader Larb (then Invader Skoodge). These rat-like aliens later made their only actual appearance when the Irken Armada attacked their home world in "Battle of the Planets".

Meet the hostile rat-like race. [Invader Zim]

Invader El is one of the few female Irken Invaders, and it is unknown what planet she was assigned to or if she already completed her mission.

She is one of the few Invaders without spots on her PAK, but one of the many without stripes on her uniform, although these may be coloring errors.

Invader Gooch is an Irken who was seen waiting in line on Devastis, presumably to take the test to become an Irken Elite. He apparently passed, as he is now an Invader. Gooch is hunched over, and has a long neck, extremely short legs, and ruby eyes the shape of a squashed oval; whether that is the norm for him is unknown. His PAK is much larger than that of the average Irken and is probably the cause of his hunched back, much like Invader Slant. He apparently passed, as he is now an Invader.

Invader Skutch is an Irken Invader who was assigned to an unnamed striped planet with two moons. He was seen in the episode "Planet Jackers".

Just white 12" vinyl. It can be played with vinyl player, or you can re-record your pieces of music on it. Mostly, white vinyls are promos or test pressings (but also can be blank vinyl without songs), and text on it can be written by pen on it's white disk center (or other many variations, like white sticker with tracklist etc.). Can be warped, or cleaned with good quality, or cracky with many crackles (depends on how carefully you save the record). Mostly LP (long play - about 45 minutes).

Just white 12" vinyl.

Invader Tim is one of the few Irkens to have a human name. At the Almighty Tallest's gathering to watch Zim train on Hobo 13, Tim bet two thousand monies that Zim would be chopped in half. He is one of the few PAKless Irkens, although this could just be an error made by the drawing crew. Tim has a very prominent forehead, making his features distinct from most other Irkens. Tim was assigned to an unknown planet.

Invader Slant is an Irken Invader. He appears to have a hunched stance, giving him a slightly averted upside down L-shaped figure, which is exaggerated by his unusually square head.

Invader Pesto is an Irken Invader. He is one of the many Irkens who doesn't have stripes on his uniform, and has unusually short antennae.

He is one of numerous Invaders who don't have any ports on their PAK, although this is likely a coloring error.

Invader Sploodge is an Invader with off-pink eyes, off-green skin, similar to Invader Pesto. He has a stripeless shirt and a spotless PAK; he was assigned to an unknown planet.

Invader Sploodge is an Irken Invader, and one of the few Irkens who have pink eyes, rather than the more common red.
