zim and zim. also, dib and dib and gaz and gaz it all started out as a purely crack thing. i was developing "my" versions of them, and came to contact *lady-nephero about her own versions of the boys (and girl) i was intrigued by her stoyline and her "bara" versions (as she has a much more refined and masculine style than me) so. we started making fun about how the "bishi vs. bara" meetings would go and... from crack came seriousness and two storylines suddenly fit so well together, that they became canon for us.
the explanation is like this (and i'll give my best to keep it somewhat short) my zim was made. he wasn't just a regular irken clone like all others, but he was altered. he alone posesses a rare few female genes that make him queen (in a way) due to that, his PAK was messed with by former irken tallest miyuki (as to not have zim endanger his position (another headcanon of ours. all irkens are male, even tak and tenn and miyuki, they're simply taking a more female gender role, aaaaall will be explained later on in more details)) bla.
during the happenings of an unaired episode ("the trial") zim gets called back to irk for an existence evaluation trial thingie. i took that and made it happen. BUT. we added a thing. when zim's connected to the control brains, he causes them to short-circuit (he does it in the script) BUT.. the very moment this happens, another irken drone with an unknown name was hooked to the main computer as well, which results in zim's entire PAK being copied over to that drone.
so, unnamed drone basically BECOMES zim, a 98% identical copy of him, with the loss of his original data.
he discovers this much later and is understandably devastated, because he has lost his own identity. he stops calling himself zim and HIS dib and he decide that he'll be Raz from there on.
so, zim & zim = zim & raz.
now, about the dibs. i think I've hinted on it before in my arts, but the dibs are clones. 100% identical copies of membrane, created at different points (thus they're not the same age) and each set into a different social setting. her dib has had much parental support from his "father" and has become a paranormal investigator for the swollen eye network. my dib has been intentionally placed into a hostile environment, with no parental support, abusive sister (more on gaz later) and horrible peer group.
each dib has a name file. my dib's full name is Dibri - determining Impact of aBuse Relative to Individuality her dib's full name is: Dibeid - Determinging importance of biological and environmental influences on development
so... basically.. everything bad that has happened to my dib was fully intentional. that's also why he'll finally loses all faith in mankind and fully sides with zim.
my dib also will never meet any of his siblings, Dibeid aside. there are 14 living dibs, scattered all over the globe, and there were 72 tries to create clones. (72 tries, 14 turned out well enough to live)
erm... so, each zim has one dib and for each dib there's one gaz.
the gaz' are also experiments. also artificially made, but no direct clones. they are experiments with esp powers, psychic abilities and such (the in-series' gaz has some pretty freaky moments) my gaz has only very mild powers her gaz has a lot more powerful abilities. they share a mental link they're not really aware of, until much later, that's why her gaz recognizes "zim (raz)" even though she has never actually met him in person.
again, this'll be explained during the story in much more detail
sooooooo,... long thing short: there's zim, the semi-hermaphrodite irken queen with the babymaking faible... and there's raz (who basically is a copy of zim), who was, and later is again, a soldier and loyal as fuck to the empire and his queen (they become buddies XD ) my dib likes raz... but he has NO love at all for his clone brother. no love there's not even a word for how much NOT LOVE he has for him.
