When making an Irken, you must remanber, that they are half cyborg, whom can not love. Their body is in fact a puppit.
When making a bio, of your Irken traits inside, also remanber, Irkens only have Four organs. Brain, Heart, an one other small organ, below and the most known, Squeedly-Spooch.And they have square cells, much like a plant's.
Tongues, look like EarthWorms.
The three fingers, are really only two, an thumb.
The Pak, is much like the brain, in fact, the Irken can live without its brain, if he/ she has a Pak.
Irken eyes, are glossy, they have sensitive to irritants. The Eyes may be belived to just be put there, when being born, so some Irkens may have one eye. Also thining of the way Irkens heal, you must remanber, their eyes are made of a skin like cells.
The, eyes are only 3 colors, Red, being,the most that should be used, purple being very rare, and green in the middle. Only one Irken has a different colored eyes, who is Invader Dookie.
Irkens can not give brith, they are only made by cloneing, the irkens do not have a sexually way to reproduce also.
Male Irkens, are always, have the same antenntas, the females, have the curled antenntas seen from Tak, some may be a little longer, or shorter, but, not very long! Most female Irkens have a little lighter red color then males, mostliky the some thing with the other 2 colors.
Irkens, don't always have perfect disguise, they mostly look alot like Zim and Gir's, Tak is the only one who got her's ok.
Most Irken Weakness, should already be known, to you.
Irkens do have their own language, which is the known, writing you see, and the names, plus the way Zim and Gir were speaking in "Mysterious Mysteries". No, it was not just some random geberish.
When trying to write Irken you must remanber,it is only A-T.
When making the Irkens name, spell it in Irken first, so if it has letters Irks do not use, it is said different in Irken, so when spelled in English, you may say, it is spelled with other letters, just like in using, I, and not Y, like in a name like Mai, can be used, or May it would be spelled in Earth english.
Names must be picked carefuly
When wanting to make your Irken OC, made at the Tallest, always think, what made them hate them, mostly because, the Tallest, do not make major changes, the, Contorl Brains, do.
Their are only a few ranks for an Irken: servant, food service drones, invaders, diplomats, those who aide the Tallest, and the Tallest themselves. So they can not be some kind, of hunter, or back-up leader!
The outfit changes are, ok, but, then again, there is nothing about them having some out of place.
Remanber these things when Making an Irken OC!
