Intro: have you ever felt so alone and all of your ideas that you had no one to talk to and you ever just thought I really need a sidekick or a Lackey not in a mean way of course just you know that person who always goes along with everything crazy and everyone has someone like that in their life or at least most of the time you're one of those few people such as myself who do not you're lacking one thing that is epically needed in your life his name is GIR!!!
Type: Mini Muse
Species: SIR unit
Gender: Nonbinary but appears Male invoice
Age: 1 earth year
Offerings: the smell of sweet things
Personality: is the insane, hyperactive robotic assistant of Zim and the closest thing the incompetent Irken has to a friend, having been constructed from scrap parts by the Almighty Tallest just before it was handed to Zim, instead of a regular SIR (Standard-issue Information Retrieval Unit).
Communication: dreams, Morse code, many languages and telepathy
GIR is happy-go-lucky, enthusiastic, energetic, excitable, and extremely hyperactive, and will eat just about anything, regardless of whether it is edible or not. Most of the time he spouts nonsense, but does have a few, short moments of clarity: for instance, in "Walk for Your Lives" he actually contemplated whether making the explosion go faster would make things worse ("But if the big 'splody goes fast, won't it get all bad?"), and in "Bad, Bad Rubber Piggy" he questioned the wisdom of sending a machine into the past to destroy Dib.
GIR usually fools around when Zim gives an order, and always goes right back to what he was doing before once he has completed the order (which is only done occasionally) or, more often, when Zim leaves. Zim has described GIR's intelligence as "bad"; indeed, the little robot is often one of the many reasons why Zim's plans frequently fail. GIR has also been known to disobey orders whenever it conflicts with getting something he wants, such as rubber piggies or food.
GIR drinking tea and eating cupcakes.Zim has taken advantage of GIR's poor intelligence in the past, having once attached GIR to a power amplifier in "Plague of Babies" to incapacitate Sergeant Shnooky and his underlings with an amplified wave of the little robot's stupidity. However, despite his stupidity, GIR also has shown an occasional manipulative side, having used his antics in the past to bend others to his will.
Unlike Zim, GIR does not mind getting involved with typical Earth culture; on several occasions he has even admitted to loving Earth. GIR also has a strong love of Earth snacks, such as tacos, taquitos, candy, chocolate, bubblegum, waffles, cupcakes, tuna, biscuits, chicken with mayonnaise, pizza, Suck Munkeys, numerous Poop products, mashed potatoes, muffins and corn. He can eat and enjoy them, even though he is a robot, and was even shown somehow becoming fat in the "Halloween Spectacular of Spooky Doom" after stealing and devouring all of the Halloween candy from trick-or-treaters.
Despite his sub-par disguises, GIR is actually quite good at blending in with the humans, due to his behavior and intelligence being similar to theirs. In "Attack of the Saucer Morons", he even befriended multiple teenage human females. Similarly in Issue 26 of the comics, GIR disguised himself as a human boy to able to go to skool with his master, in the process he befriended several skoolchildren, easily blending in and becoming one of the "popular kids" on his first day, even when the kids saw him in his dog costume, they still loved him.
GIR watching his favorite show, The Scary Monkey Show.His favorite assignment from Zim is "monitoring Earth broadcasts" (in other words, watching TV); when doing so, he usually watches The Scary Monkey Show, which he has declared to be his "favorite show".
His favorite movie is Intestines of War, which he has seen over one hundred times ("FBI Warning of Doom"). GIR is also very loyal to Zim, despite disobeying him often and mainly being a hindrance to his plans.
There have been times where Dib has "tricked" him into doing things, like putting a camera in Zim's Base in "Zim Eats Waffles", and even inviting him into the base during "The Frycook What Came from All That Space".
This is probably because Dib doesn't seem to bother GIR as much as he does Zim, saying in "Planet Jackers" that "he seems nice". By the time of "Mysterious Mysteries" however, GIR seemed to be aware of Dib's antipathy toward his master, and flat-out defended him, though this was probably because Zim told GIR exactly what to say.
GIR also seems to possess the uncanny ability of bending others to his will as he was able to make Zim dance in the elevator of the base during "Invasion of the Idiot Dog Brain" and more surprisingly, Gaz in "Tak: The Hideous New Girl".
GIR does not hate or dislike anyone, which contrasts very sharply with Zim, Dib and especially Gaz. He instead approaches everything in the world, living or not, with boundless affection and enthusiasm.
GIR in the rare Duty Mode.
Every so often, GIR will display brief instances of complete functionality. Usually triggered by Zim giving an order, this "Duty Mode" is made manifest by the teal parts of GIR's body and eyes flashing red, his voice changing from high-pitched to harsh, deep and rough, and GIR himself snapping to attention, alert and utterly obedient. He concludes it with a salute and response of "Yes, sir!". These random bouts never last for long, though, and after a few seconds, GIR is right back to his gleeful, hyperactive self.
GIR's personality changes drastically after an intelligence boost.
As it turns out, however, this brevity is probably a good thing for Zim: As he learned the hard way when he tried to lock GIR into Duty Mode via a Behavioral Modulator, if GIR was fully lucid all the time, he would quickly realize that his own master was a threat to their mission to conquer Earth, and would quickly eliminate him.
