These random bouts never last for long, though, and after a few seconds, GIR is right back to his gleeful, hyperactive self. He concludes it with a salute and response of 'Yes, sir!'. 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. However he does have a few brief 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.Д®very so often, GIR will display brief instances of complete functionality. Most of the time he spouts nonsense and usually just fools around whenever Zim gives an order. GIR will eat just about anything, regardless of whether it is edible or not. He is happy-go-lucky, extremely hyperactive, and the closest thing Zim has to a real friend. GIR is the robotic assistant of Zim in Invader Zim.
