Once the Almighty Tallest[that's us] got rid of him they began on Impending Doom II... once Zim heard of it he quit his banishment and rushed over to the Almighty Tallest to be asigned to a planet, well seeing as how they wanted to succeed this time they sent Zim to 'The Mystery Planet'[Earth]. After the asigning of planets Zim and his G.I.R.(G...I'll get back on you with that one) but gir was really just made from a bunch of scrap metal and screws and I think a sandwich, to make Zim think he was getting his very own 'speaciel' S.I.R.(I forgot what it stands for...
