Yeah, been watching a lot of Invader Zim again, and this idea just popped right into my head. I won't keep you much longer. Enjoy the story.

*I don't own Ben 10 or Invader Zim. If I did, Gir would be ruling the moon and Ben would have married someone other than Kai in canon.*

Prologue - Hatching of a Young Irken

"How's your son doing, Topaz?" asked a woman's voice.

"He's been dreaming sweet dreams, Sapphire. In fact, he's almost ready to hatch." said another female voice.

Walking down the corridors of the Irken Hatchery on the planet Irk, two females of a certain alien species are conversing with each other. But these are no ordinary members of their species. These are two of four leaders of their entire race. The Almighty Tallest of the Irken Armada.

These two are the females of the small council of leaders who help govern Irken society. Unlike their male counterparts, these two look drastically different from the rest of their people.

For one thing, the two male members of the Almighty Tallest are indeed the tallest males of their species. They're about as tall as a full grown human male of average build, however they have some disadvantages to being so tall. Their legs are so thin and spindly that they can no longer support their weight. Not without collapsing in on themselves at least. To counter this physical weakness, male Irkens who become the Tallest normally develop Telepathic powers such as levitation to help them move about safely. But until they develop this power and learn to control it without even trying, they use a specially designed hover belt to hover from place to place. They also are regarded as technological geniuses, rivaling even the likes of the Galvan and the Cerebrocrustaceans.

Then there are the female members of the Almighty Tallest, and they developed quite differently. The two female members, while retaining some features that are common amongst the Irken race, they actually evolved over time to look more like human women. In terms of their figure, they have a body type similar to that of Transmetal 2 Blackarachnia from the Transformers Beast Wars series, having that hourglass figure that many women work very hard for. And since their legs aren't so thin and spindly they can support their own weight easily. They still have green skin like all the other Irkens, and they do have a pair of antennae on their heads that stick out of their long black hair, however they lack the large pink compound eyes that most Irkens possess.

As a matter of fact, all Irkens from these two particular Almighty Tallest's branch of the species look more human than Irken. There's more to these two Tallest, but we'll get to that later.

These two Female Irkens are called Topaz and Sapphire. They may share the same looks physically, but you can tell the differences between the two by a few factors. Topaz has yellow eyes, yellow markings on her PAK, has a small scar on her left cheek from an earlier battle, and her clothes have a lot of yellow in them.

Sapphire has stunning blue eyes and markings on her PAK, no scar, and wears a flowing blue dress due to spending much of her time operating from Planet Irk. Her voice is also slightly more mature than Topaz's.

Right now the two are on their way to the Irken Hatchery to oversee the birth of the latest batch of diplomats and Invaders. And since Topaz has a hatchling on the way, she's there to make sure he stays healthy until the time comes for him to be born. Yes, her child is in that stage of development where you can tell the gender.

"Your child is due to hatch any day now, Topaz. You and your mate really should start picking names." Sapphire advised.

"We've already decided on Zim." Topaz replied with a grin. "My husband and I just know that, whether he's an Invader or a diplomat, he'll do us both proud."

She giggled as she remembered something about Irken biology.

"The best part about us Irkens developing our young in artificial wombs: no labor pains."

The two female Irkens had a good laugh about that, knowing that all species of life that give birth to live young, sapient or nonsapient, have to deal with serious pains from giving birth to their children. But that's what makes those females so strong. A male would have died from such pain.

Topaz and Sapphire arrived at the hatchery within minutes and saw what they know is normal for their species. Hundreds upon thousands of incubation chambers where infant Irkens float in embryotic fluids, waiting for the day they'll be born. Suddenly, one of the pods started flashing green which signaled the child inside was ready to be born. Topaz smiled with glee and ran inside. It's time for her son to be born.

The pod was grasped by two robot arms that carried it towards Topaz and quickly broke open the thin glass shell so the Irken baby, which is the size of a human baby, could fall forward into his mother's awaiting arms. One of the robot arms quickly applied the PAK to the infant so he won't die soon after being birthed, and the other applied a jolt of electricity to jumpstart the child and his PAK. Once this was done, the child's eyes opened up to reveal that they're pink just like those of his father.

"Welcome to life, my little Zim." Topaz said with proud tears in her eyes. "I'm your Momma. And I'll always be here for you."

She held her little one close while Sapphire went to summon her fellow Tallest's mate. He needs to meet his child as quickly as he can.

*To Be Continued…*

Yeah, just a little prologue as a way to show this universe's Zim's origins. It'll go more in depth with the next chapter. But for now, I hope you all enjoyed this chapter. See you all next time.
