I hope you guys are enjoying this because I am! Invader Zim belonged to Jhonen Vasquez and Richard Steven, but all of the OCs involved belongs to me.

In a dark, foggy place where there are purple puddles nearly everywhere, dead trees, many platforms where everything is distorted and a bunch of black, gooey creatures with glowing purple eyes and disgusting veins that looks like it's pulsing despite its artificial looks.

Hana, covers in scars and torn up armour, pierces through those monsters as if there were nothing to her. Then again, she was lucky she has the Alter arrows, one of the Deadly Weapons that are effective against the Shadow Dragon itself many years ago. And those monsters are the remnants of it and change their appearance due to the environment.

"That's... the last of them..." Hana muttered as she is covered in black blood and puts away her arrows. "I... I have to find a way out! I... I need to find Zim!"

The artificial human desperately drags her own body as she's looking for the exit. It's been three months since she fell into the underworld and finally escaped from her creator, but at what cost? She's forced to survive through those abominations and the hellspawns; one of the residents of the underworld who are ferocious and kills any intruders at sight, including her.

She went up to an edge where she jumps to another platform. She looks up and sees a waterfall of blood upside down, which she jumps in to head to another platform. Once she did, she spits out the blood, which tastes a bit like the fog; rotten foods, but also metallic.

"Ugh..." Hana groaned. "I... I just want to go home! I just want to see Zim! Is that too much to ask!?"

Suddenly, she hears growling noises, but those growls aren't from those hellspawns nor the remnants. She slowly turns around and turns pale once she sees a bunch of wendigoes surrounding her; monsters that were once human until they committed cannibalism, in which case, they were cursed to become wendigoes once they die and the majority of them are in the underworld, where they would starve to death due to the fact humans can't go to the human realm, so they were rare as most of them starved to death.

Naturally, its' desiccated skin pulled tightly over its bones. With its bones pushing out against its skin, its complexion the ash-gray of death, and its eyes pushed back deep into their sockets, those Wendigoes look like gaunt skeletons recently disinterred from the grave, with its bloody lips and long tongue; readying to devour her.

But, even though she's mostly artificial, she does have a few natural organs like her head, her private parts, heart, and skeleton. Don't ask how Ate obtain those things; the truth is weirder than fiction, after all.

All of those monsters jump on her as they desperately try to eat her, but Hana quickly hovers away from them, causing a collapse between them. The wendigoes start growling at each other and desperately killing each other in an attempt to win the competition; the reward is eating Hana.

She hovers away while looking back. She floats to another platform as she desperately clings to her life; not wanting to die. Not yet!

"Please! I can't die now!" Hana thought while panicking, "I-I want to see Zim and my sisters first before I die!"

The wendigoes notice her escape, which they stop fighting and chase her down like a bunch of hungry foxes hunting the last surviving rabbit. She stops hovering as she collapses to the floor out of tiresome. She turns around as she sees a bunch of wendigoes jumps as they are ready to kill her. She closes her eyes and thinks, "So... this is it... sorry Zim... sisters... I never even get the chance to properly tell Zim... how much I love him..."

Suddenly, she hears a powerful thunder noise and splattering. She slowly open her eyes and notices she's still alive, which she gasps and quickly looks up; she sees an unusually tall irken who is around the Tallests' height, well built, a blue PAK and wielding an electrical bastard sword. He wears an blue coat with some black armour.

The irken is completely covered in blood and in front of him is a bunch of corpses.

"You okay?" The irken asked him.

"Y... Yes..." Hana replied as she slowly gets up and asks, "Who... who are you?"

"My name... is Vasilios, the guardian of Pandora's box," The irken introduced himself. "What are you exactly? You're definitely not human, considering humans can't enter the Underworld without severe consequences."

He is right; because of the fog which is extremely poisonous to everyone, including gods and irkens. The only ones who can survive are spirits, Hades and the Alter units that are built-in with poison immunity. Hana takes a deep breath and answers, "I'm... an Alter unit; created for the sole purpose of surviving the Underworld... and to retrieve the Pandora's box..."

"... You don't seem like you want to retrieve the box," Vasilios commented, which Hana nods.

"I... I don't understand why my creator gave us free will, but quite honestly... I don't give a rat ass about that stupid box!" Hana said, "I just want to get out of here and see Zim!"

"Z-Zim!?" Vasilios gasped.

"Do... do you know him?" Hana asked him.

"... No, I don't." Vasilios lied to her.

"I don't believe you." Hana admitted.

"Well... I... I don't like talking about my secret to strangers." Vasilios told her.

"Fair enough." Hana replied.

Vasilios turns around and walks ahead of Hana as he says, "Follow me. I know the underworld from the back of my head, so I can get you out of here."

"Really?!" Hana asked excitedly.

"Yes," The guardian replied. "Let's go."

"So... how long have you been aware of my existence?"

"I detected you for three days now," Vasilios replied, "The only reason I never gone after you is because I thought you're going after the box and you're pretty far away, so I didn't bother. Then I noticed you're not after the box..."

"You literally waited three days to save my life," Hana groaned and thinks, "Wow... he has the same intelligence as Zim... never thought he's that dumb..."

"Hey! Shut up!" Vasilios shouted.

Hana just rolls her eyes and the duo continue on their walk. After a few hours in the underworld where time is much slower here than on the surface. A minute on the surface is an hour while three days equates to three months on the surface, as the underworld doesn't know the concept of time, so its time is much looser than on the surface.

Finally, they arrive at a dark portal with skulls surrounding it. Vasilios opens up the gate and says, "Also, you are aware time here is much slower than the surface, right?"

"Y... yes... only little though," Hana replied, "My creator did mention time here is different, but not sure how."

"Since I'm the only one other than Hades who is aware of time," Vasilios explained, "Even though you been gone for three days here, it's actually been three months for the surface world."

"T-Three months?!" Hana gasped in shock. She couldn't believe it... she's been gone for three months.

"Yes, I and Hades are the only ones who can open the portal from this side," Vasilios told her, "But we can't control where you be teleported. It will be purely random, so keep that in mind."

"... I will," Hana replied. "Thank you."

"It's no big deal," Vasilios replied. "Be careful, with Ate going around."

"You know about Ate?!" Hana asked in shock.
"Unfortunately, yes, but that isn't important right now," Vasilios told her. "You should get going before the portal closes up. It can only be open once per day, which would be another month."

"Right!" Hana shouted.

Hana rushes into the portal and the portal closes off. The irken takes a deep sigh and walks away from the portal as he thinks,
"... Just what's happening in the surface world, sis...?"

(Meanwhile)

Hana jumps out of the portal, where she scans her surroundings. As she looks around, she sees the famous Red Square, which she quickly realises where she is.

"Belortau..." Hana muttered.

Belortau, formerly known as Moscow back in the modern era, just like the Imperial city was known as DC Washington and Aromore was known as London. A lot of capital cities was renamed to befit the new era, though the other cities kept their old name for an unknown reason.

But, Hana quickly shakes her head; this isn't the time for a history lesson! This is where she has to search for Zim and her sisters!

"Zim... Drei... Lily... I'm coming!" Hana thought as she flies off to look for her family and friends.
