|Known Residents|| Zim|
|First Appearance||The Nightmare Begins|
Zim's Base, or Zim's House, is the home of Zim and GIR, and later on, Minimoose. When Zim and GIR reached Earth, they found an area between two apartment buildings, and, using an Irken device, created a base founded on what Zim thought was normal Earth housing (since GIR was of minimal help). It is a tall, green house of great disproportion. It has a satellite dish on the top, two puffer fish, and a sign that says "I Love Earth". It also has several Lawn Gnomes out the front, which are part of the house's defense system. Though they can easily destroy humans, it is seen in many episodes that passersby can infiltrate with ease.
The walls of the house appear to be capable of changing shape on command; in episode Plague of Babies, Zim is able to ask the house to make a window in the attic, which the house can do without removing a piece of wall in any conventional means.
Zim's base has a main floor, an attic, and a series of underground floors which lead to the actual base. The main floor has two large rooms, about equal in size. The first room is a hallway/living room/television room. It consists of the front door, two closets (where the RoboParents are stored), a large red couch, a small chair,a very large television set (an equivalent to a wall-mounted plasma TV), a picture of a green monkey that doubles as a two-way video communication screen with the Tallest, and an entryway to the kitchen. There is a small picture of a squid by the doorway. The front door has a very interesting feature; instead of a peephole, Zim presses a handprint-scanning device that appears on the door, causing the door to vanish and revealing anyone that knocks on the door or rings the doorbell, as reveal in Tak: The Hideous New Girl.
The second room is the kitchen: It contains the typical furnishings found in any ordinary kitchen: a table with two or more seats, kitchen supplies, cabinets, a refrigerator, and a toilet by the far wall that functions as an elevator to the lower levels of the base. Above the toilet is a poster that says "I eat food" (taken directly from Johnny the Homicidal Maniac, as one of Johnny's constantly changing shirts) and on another wall is a poster that says "Earth Food Rocks!". On the other wall, facing the living room and next to the table Zim and GIR eat on, are posters that say (from right to left) "Biohazard (with logo)" and "Meat is Best!", as revealed in Battle of the Planets. The first floor's ceiling seems to be made of an arrangement of claw-like pipes.
The layout and overall floor plan of the subterranean base itself is not entirely known, but there is an armory, a repair bay, a large circular room containing the house's brain, several labs, a holodeck, a storage room, an observatory, a large room with a control panel and a huge viewscreen, a teleporter bay (used to access Zim's space station) and various other rooms and hallways, though when zooming in through the dirt it seems to be composed of spherical chambers connected by pipes. The observatory appears to be the largest and deepest part of the underground place. The color scheme of the underground floors consists mostly of shades of red, magenta and purple.
The attic is where the Voot Cruiser is located. It is also known as the "Launch Hangar" in Battle of the Planets. The attic is also located in the roof, which can open up for access to the Voot Cruiser's flight capacity. The attic has also been seen receiving long-range space probes that were sent out into space.
Facts of Doom Edit
- The house is capable of separating from its base and moving on its own via its robotic dog form. This occurred when GIR's mind was accidentally inserted into the house's brain in Invasion of the Idiot Dog Brain. How GIR knew or activated this is unknown.
- It is shown in The Nightmare Begins that Zim's base requires an incredible amount of power, as shown by the massive power cable going into two nextdoor homes. The residents, even though plagued by power loss, don't seem to either notice or care.
- Above the toilet in the kitchen is a poster, saying 'I Eat Food'. This is referencing one of Jhonen's earlier comics, Johnny the Homicidal Maniac. In one comic, his ever changing shirt bears the same message.
- It is shown in Backseat Drivers From Beyond the Stars that Zim's base is located somewhere around Pennsylvania in the American Midwest when the the Massive locks on to Zim's signal, displaying Zim's location.
- In the intro Zim's base is purple and pink but during the episodes Zim's base is green.
- In The Nighmare Begins, Zim draws his base on a tablet first. If you watch closely, this shows that Zim is left-handed.
- Zim's base currently is sold online, called the "house set", containing a Duty Mode GIR figure, and all the episodes that have currently aired.
- In the series Ben 10 Omniverse, the titular character enters an underground facility by flushing a toilet, in a similar manner to how Zim enters his laboratory.
