"The reason Zim repeats himself a lot, and yells so much is because his antenna are damaged from a lab accident, and he can't hear very well. He doesn't do it just to be annoying"

. . .
I didn't know he was deaf, did you?
I thought he was just being annoying or dumb because of his size XD
And what about this "lab accident"? Was that time Zim created the goo monster and Tallest Miyuki was killed by it (read the script "The Trial") ?
Finally after years something from Invader Zim that I didn't know, lol
People, I know that's a headcanon
(the person who posted that image calls "ZIM HEADCANON", doh XP), but I have to say it was really well thinking, right?
That explains lots of episodes XP
Also, for be just a headcanon I can add that it could not be an accident what made him deaf. Maybe that's the defection Zim has. I mean, antennae functions are everything for the Irkens, for hearing, for smelling, for wheater, for guideness and stuff.
Anyway... wanna read other headcanons that I really liked?"Invader Zim takes place 11 years after the events of JTHM, in the same city. It's far more advanced technology-wise and less violent and
inappropriate, because 11 years ago when Dib and later Gaz were born Professor Membrane started to spread his influence around since he wanted a better world for his children. Nny is still living, and in fact he traumatized Dib when he was a baby, which is why he appears as a demon in the halloween episode where we went into Dib's imaginary nightmare world.""In Backseat Drivers, when Red is locating Zim on Earth, he zooms into SouthernCanada or Northern USA. IDib and Gaz are Canadian!"
This last one actually I already knew it, the whole episode shows they are from Canada XD
