They say Dib has a big head but Gaz has a big ass forehead
He's very tired
Semi-realism of someone that doesn't exist, I usually never do realism
What if Zim got tired of how stupid humans are thinking he's humans when his disguise his obviously flawed and you goes to school without his disguise and everyone is like "I like your alien costume Zim!"
Dib and Zim both then have a fucking mental breakdown
Headcanon:
Purple has a natural high pitched kinda feminine sounding voice, which is technically canon cause of his voice actor, but he's able to slightly deepen his voice but he will only do it as a prank to mess with Red or other Irkens sometimes, it catches everyone off guard whenever he does it and Purple gets a good laugh from it every time
Sorry I didn't post today y'all, my power went out so I drew one of the Tallest!
They're so fucking stupid
Being Irkenkin is literally just having no family in your life/having no family in general, no great grandparents, no grandparents, no aunts, no uncles, no cousins, no siblings, no biological dad or whatever
Zim says Hi!
No other Irken in the Irken empire can ever be like Zim, nobody can even come close to the shit Zim can do, no one has the balls or the guts to do what Zim does, not even the Almighty Tallest. Irkens are literally known for being like crazy and cruel most of the time but nobody competes with Zim and most of the time the crazy stuff Zim does is on accident!
He literally swallowed human children organs just to blend in, and he dropped a giant water balloon from space on Dib just because Zim was feeling petty that day
Zim essentially sees everything as a game almost, he thinks everything is in good fun most of the time due to his delusions, he's not afraid to do crazy things so imagine what would happen if he did crazy stuff on PURPOSE
This might be a stretch but hear me out:
I've noticed whenever Zim isn't interacting with anyone, like when he's in his own base he won't be his "usual self", he'll be more calm and serious but whenever he's around others like Dib, Gaz, other Irkens, literally anyone else besides GIR, he acts stupid and crazy. Zim is also very smart and I think he's more self aware than he pretends not to be
In that episode where the Control Brains sent Zim to foodcourtia for the first time Zim literally said he doesn't need a vacation, he saw working on foodcourtia was a VACATION but as soon as he realized that it wasn't he wanted to escape so when he heard that the Almighty Tallest were giving out invader missions to the elites he knew he had to get himself one so why he doesn't have to be on foodcourtia working for Sizz-Lor so he flew his ass over to Red and Purple and begged for a mission but they told him no until Red got the idea to send him to earth, if Red never got that idea Zim would be god knows where, either back on foodcourtia or in prison. And when Zim first went to Red and Purple for the invader mission he said he "quit" being banished. And when Red and Purple gave him GIR, Zim literally said "Is it supposed to be stupid?", he knows that GIR isn't a normal SIR Unit. There's a small chance that Zim knows that everything is fake but he uses it to his advantage cause if he started to "notice", he wouldn't be on earth anymore, so Zim sees his mission as a vacation because Zim knows he's the only one who can get away with anything so he got his mission so why he didn't have to deal with consequences so he pretends, mostly, to be stupid and unaware of everything and he messes with everyone, Red and Purple fully believe it cause it's canon (I think) that Zim, Red, and Purple have known each other since childhood so Zim could've just played everyone, including the Control Brains
He just wants to do whatever he wants without consequences and everyone let's that happen most of the time because everyone is convinced that Zim is plain out dumb but he's not cause he has been in the scientific field, just like Professor Membrane, years before he came to earth, whenever Zim's alone he's suddenly "smart" kinda
I know I sound crazy but y'all just need to hear me out
