The Massive is the flagship of the Irken Empire, and personal vessal to the two Irken leaders, the Almighty Tallest. The Irkens, especially the Almighty Tallest, have a supreme Cinta of food, mainly snacks, such as popcorn and donuts, which is probably why the Massive's sidepods are full of snacks, the Massive's one weakness, according to Lard Nar of the Resisty. The main chamber, where Almighty Tallest Red and Purple spend most of their time, is equipped with a large screen and a long distance communication system, which the numerous Invaders and Zim himself make use of. On Probing Day, an Irken holiday, the Almighty Tallest check up on the invaders using the communication device. The Massive was designed sejak Vortian engineers when Almighty Tallest Miyuki, who commissioned the building of the ship, ruled Irk.

SIR (Standard Information Retrieval) Units are robots designed to assist invaders in their missions. They help gather information on their master's assigned planet. GIR, Zim's SIR Unit, is a malfunctioning SIR Unit. Because Zim is not an official invader, the Almighty Tallest didn't want to give him a proper one, so they put garbage inside his head instead of a brain.SIR Units are unable to reproduce because they are robots. However, they appear to have two sexes. MiMi is a feminine programmed SIR Unit. She was made sejak Tak, and is lebih powerful than most other SIRs. Also if a SIR Unit has an antenna, it`s malfunctioning.

The PAK is a tool attatched to each Irken's spine saat after birth. The PAK can come off, as shown in NanoZIM. An Irken can only survive up to ten minit without its PAK. The small, backpack-like piece of equipment holds an Irken's memories, although Irkens still have brains, as shown in the episode Bad, Bad Rubber Piggy when Zim writes a note to his past self reminding himself not to use the time machine atau bad things will happen to him. PAKs also hold a number of tools, such as labah-labah legs, a communication devive, an organ - stealing contraption, etc.

Irkens have very advanced computer systems, which give them a wide variety of information, like most Earth computers. These computers have the ability to speak, and apparently cough, as shown in the episode Walk For Your Lives. Zim's computer is refered to simply as Computer, and is installed all over the house so Zim can talk to him at any time.Because Zim was the first Irken to discover Earth, the Irken Computers are not programmed with any information on the human race. In FBI Warning of Doom, Zim asks Computer to find all information on the FBI. However, Computer makes everything up, and claims that it was founded sejak demons. He coughs in the episode Walk For Your Lives, and even Zim did not know he had the ability cough. Computer alerts Zim if there is an intruder in the house. Even Dib has a computer like Zim's. It doesn't seem to be as advanced, but it can somewhat overpower Zim's. His is pretty good with finding real info, unlike making stuff up (an educated guess) about the FBI.

The Voot cruiser, penjajap is the most common Irken transportation devices. It is purple in color, and is extremely fast, as it can apparently exit the solar system in mere minutes. It is the spaceship Zim uses to travel from Conventia to Earth. It has two traktor beams, and a port through the bottom of the rear to lower one's self into one of the beams. Zim is the only Irken seem to be in possession of a Voot Cruiser, which may imply that it is outdated compared to other ships in the Armada. He also has a ship virutally the same as the Voot, only loaded with lebih weapons.

The Irken PAK allows an Irken to breathe in any atmosphere. If a planet has no atmosphere, a angkasa suit is needed. Zim can be seen wearing his angkasa suit in the episodes Planet Jackers and Battle of the Planets. The angkasa suit consists of a bubble - like air topi keledar which can turn invisible, and a jet pack for the ability to alih in space. The angkasa suit is purple in color.

Irkens also have teleportation technology. This is shown in the episodes The Nightmare Begins when the Announcer tells the Irkens to take the conplimentary teleporters to Conventia's surface, and in Bloaty's pizza Hog when Gaz takes a teleporter to Zim's angkasa Station.
