Invader Zim is created by Jhonen Vasquez. Zim is an outcast of the Irken race. He was banished
to a planet called 'Foodcourtia' because he almost destroyed his home planet after Operation
Impending Doom 1. He 'quit' his banishment after he heard about Operation Impending Doom 2.
Zim shows up at the great assigning. He begs them to let him become an Invader once again, but
the Tallest give him a sandwich to try to get him to go away. After being fed up with him, they
send him to conquer a planet that they don't know exist. That planet is Earth. The Tallest
start to assign everyone their SIR units. To further make fun of Zim, they make a unit for
him out of spare SIR parts. Of course, this robot is very stupid and they tell him it's
'advanced'. They call it a GIR unit, and when Zim asks what the 'G' stands for, GIR starts up
and says it doesn't know and then starts bounching around all over the place. They then set off
for their mission.
Of course, there has to be something stopping Zim from taking over the world. This someone
is Dib. No one believes him when he says that Zim is an alien. They instead call him crazy
and insane. Dib trys to spoil all of Zim's plans, but never gets to expose him as the alien
he is. His younger sister is Gaz, who is obsessed with video games and pizza.
To summarize this whole show, it's really amazing and if you don't like it, you're crazy...
