after re-watching all the episodes of invader zim, i came up with what is most likely a shit theory, but a theory none the less. you see, my theory involves two things,

1.) professor membrane is an irken

2.)  Dib is a hybrid clone

lets start with my reasoning for number 1

here’s the facts:

the humans of the earth universe are very….. not smart. the professor however is a very extremely skilled scientist.

his interactions with his offspring are limited, and almost seem as though he doesnt know what it means to be part of a family.

he wears a suit 24/7 that covers his whole face below his eyes, almost like the irken technicians

his goggles look almost like irken eyes

and other scientists from the show dont have this quality.

why would an irken be on earth though? and why would they clone two children to raise?

another possible theory is that the mother was an irken, who possibly fell in love with a human? one thing remains for sure, an irken knew about earth before zim was sent there, otherwise who would put this here?

now onto theory number two~

heres the facts;

 dib seems to be smarter the average human, like their father.

dib’s mother has never been shown.

taks brainwashing doesn’t work on dib.

in the un-aired episode “ten minutes to doom” zim says that his pak is un-compatible with human biology and would’ve killed dib, but it seemed to perfectly integrate into him.

dib has been shown to be skilled in fighting, and has even pinned down zim a few times, the guy who flipped that chick from the saucer morons.

dibs shirt has this face on it

look familiar?

when a smeet is ready to be born the neutral face smiles. does this mean the irken in dib isn’t ready yet? is possible that in the un-aired “invader dib” episode was not dib disguising as an irken, but turning into one?

thats all i have so far, feel free to add your opinions or arguments!
