I do not own Invader Zim. Just my OCs Ally, Chloe, and Mr. Wilkers.

It was a bright sunny morning at the city as a young girl left her home to go to "skool".

"Another day, another good opprotunity to learn!" She said in a happy yet sarcastic tone. "And to be creeped out by that old bat Ms. Bitters....."

The girl had long yet sort of messy brown hair while wearing a red cap backwards, she has emerald green eyes while wearing baggy clothes. As she walked down the path, she heard yelling ahead, so she went to investigate it. She passed a couple of trees and found the source of the yelling: Dib and Zim. Once again they're having their usual squabbles.

"Dammit Zim, just what are you up to this time?" Dib accused the angry green skinned "child".

"That's for me to know and for you to never find out Dib beast! Now get out of the way of ZIM!" Zim snarled.

"Not until you tell me what you're up to!"

The cheerful girl walked up to the two and broke up the fight. "Ok you two that's enough! We're gonna be late and Ms. Bitters isn't gonna be a happy woman when she finds out!"

"What're you talking about, Ally? Ms. Bitters is NEVER happy about anything!" Dib said.

Zim frowned at Dib. "For once I agree with Dib stink! That old human's angrier then his sister!"

"Let's not forget that she moves like a shadow." The girl called Ally said.

Zim started to think about the wicked Ms. Bitters. "Now that you mention it......she DOES act pretty evil to even behave like a normal human being.....just what is she really?"

Ally got closer to Zim and wiggled her fingers in a spooky way. "Nobody knows......."

Zim's eye twitched from his friend's sudden spookiness while Dib stifle a giggle. Ally quickly took Zim and Dib's hands then raced to the skool with them running behind her back.

(Inside the skool)

Ally, Dib, and Zim made it inside Ms. Bitter's classroom just in time. Dib and Zim sat in their usual seats while Ally sat next to Tak. (Yes she's in this story and she is also attending the school)

"Hey Ally." Tak greeted.

"Hey Tak, what's going on?" Ally asked.

"Nothing special, just uhhhhh.....figuring new ways to torment Zim." Tak said a bit hesitatingly as if she was hiding something.

Ally smiled. She knew what was really going on in her friend's life. Like Dib and Gaz she knew that Zim and Tak are both Irkens from the planet Irk. She knows because secretly.......she's an Irken herself in human disguise. The bell rung for the beginning of class as Ms. Bitters rose from her desk.

"Alright you horrible little dirtballs that I despise so much. Take out your books and turn it to page 397 then we will begin our lesson or you will be doomed!"

Ally sighed as she took out her book from her backpack and opened it as the students did the same time. Then the bitter old teacher started speaking.

"Today we're gonna start learning about the medieval era........"

As Ms. Bitters started teaching, all the kids started listening, except for Ally. She already know this stuff since she's been to this skool after she exiled herself from Irk, 2 years ago. Now you're probably wondering why she did a thing like that? And without letting the other Irkens and her Tallests knowing? Well let's take a look into the past.......

(2 years ago when Ally used to be a ruthless invader)

Ally laughed evily as her ship sailed throughout the cosmos. She and her team of Irken soldiers had accomplished the mission of taking over the planet Iceidia. She puts the ship on auto pilot and went to the deck to congratulate her teammates. Her teammates were sitting drinking soda and eating nachos as their team leader arrived with a smile of triumph on her face.

"Good job team! The Tallests are going to be so pleased when they hear that we took over Iceidia!" Ally praised.

Everybody cheered.

"Im glad we left though....Iceidia's a very cold planet! I didn't think we'd survive there!" One of the irkens spoke as he rubbed his arms.

"Me neither!" A female irkan spoke.

Ally chuckled a bit. "Well the important thing is that we're ok and the job is finished. We only got three days until we reach the Massive, so just go ahead and relax!"

The teammates whooped with glee as Ally left the room.

(A couple of days later)

Ally wasn't feeling so good. She was lying in her bed feeling really sick. Her skin felt like it was on fire, she coughs from time to time, and she was feeling the shivers. Isa, one of her teammates came to check on her on the first day of their voyage back to the Massive, but she hasn't returned since. Ally's cabin room door opened and one of her teammates called out to her.

"Ally! Isa's dead!"

Ally managed to get up from bed. She stared at the male irken with horror. "What? What do you mean she's dead?"

"She hasn't been feeling well for the past two days! Then I came to check on her in her bedroom and she was lying dead on her bed!"

With a little bit of her strength, Ally rushed out of her bedroom and went to Isa's bedroom, she started shaking Isa's limp body. "Isa?" Ally called gently.

The irken that informed Ally of Isa's death stood outside of Isa's room while a few more came to see what was going on. After shaking Isa gently a few times, Ally finally came to the conclusion that Isa had died from catching the illness. She shook with sadness and began to cry. Her teammates were about to come in to comfort their team leader until she stop them.

"Don't come in......Im still infected with the illness....and the illness is still inside Isa's body......you must take the escape pods and head over to the Massive, tell the Tallests what happened."

"But Ally! What about you? We can help you!" One of the irkens protested.

"My illness is too dangerous for everyone else! It killed Isa! It could harm not only the others but our Tallests! Is that what you want?" Ally shouted as the tears rushed down her cheeks.

They shook their heads.

"Alright then.....now get out of here, hurry!"

Ally's teammates took off to escape the ship then Ally rushed to the ship's controls. The escape pods took off as soon as the spaceship turned around, drifting off into space never to return to the Massive or planet Irk.

(6 months later)

Ally's sickness was already broken from the third week of traveling into space but she still felt sad about losing her friend to the illness. The guilt tugged at her squiddly spooch so much that it felt so unbearable. She already buried Isa at the beautiful planet of Floren and gave Isa a final farewell. After traveling in space for six months she finally found another planet that was filled with life. It was a beautiful planet.......it will help her get a fresh new life with no worries, no responsibilities and also trying to find herself, hoping to one day forgive herself for not being strong enough to help Isa.

"This is place is perfect.....it will be my new home from now on...." Ally said to herself.

(A few hours later of landing on the earth and choosing the disguise of a human girl)

Ally used the electric pad to make her house and placed it on the ground. She quickly backed away as soon as the gadget drilled itself into the earth, then suddenly the house started to take shape. It became a medium sized blue house with a sattelite dish on top of the roof, a clean cut lawn with pretty flowers attached. After the electronic cables attaches itself to the other houses in between, Ally quietly comes inside her new home. Then she went downstairs to the basement and typed on the computer. Suddenly she heard a yawn. Ally turned her human disguised head and saw a S.I.R. robot coming downstairs.

"Master?.......Sir?" The robot called.

"Lou? Your finally up?" Ally asked as she smiled with relief.

"Yes sir! I apologize that my sleep mode lasted for six months."

Ally looked at the computer screen and kept on typing. "Its alright Lou, I understand."

Lou walked down the stairs and walked closely to his master. "Master? I notice that the planet that we're on is not Irk or the Massive. Are we going back?"

Ally shook her head. "No Lou, we're not going back. I did something bad."

"What did you do, master?"

"I'll explain everything in a minute, in the meantime would you please delete my invader personality from my PAK?"

Lou saluted to her. "Yes sir!"

Then he started to adjust the PAK as Ally started to tell Lou what happened.

(End of flashback)

Ally stared into space of her memories. As she blinked a few times she heard Ms. Bitters voice as she chanted "Doomed.....doomed......doooooooooomed."

Ally silently sighed to herself. Once again she had to listen to the creepy teacher's doomed theories. The medieval era wasn't doomed, it just had to move on to the modern era! Then the bell rang.

"Lesson over for now, go eat your lunch class." Ms. Bitters said spitefully.

(At the lunchroom)

Dib, Zim, Gaz, Tak, and Ally sat together eating lunch while talking about their mornings and today's lesson, while Ally on the other hand just complained about one thing as usual: Ms. Bitters.

"Just what is it with Ms. Bitters? She treats us like dirt!" Ally complained.

"She ALWAYS treats us like dirt! She's a spiteful old woman who hates children!" Dib said as he ate one of his tater tots.

"If she doesn't like us so much then why did she choose to be a teacher?" Gaz wondered as she played her Gameslave.

"Dunno, don't care." Tak said as drank her chocolate milk. "The only thing Im going to worry about is who Im going to take to the Halloween dance."

"Well everybody in school seems to have a date, except for us." Dib stated.

Ally just kept eating her food. "Well I know Im not going. I got to do my job after school or else I won't get paid!"

Zim, Tak, Dib, and even Gaz looked at her with suprise. "You got a job?"

"Y-Yeah, didnt I tell you?"

Gaz raised an eyebrow. "No you never tell us anything about your personal life."

Dib agreed with his sister with a nod. "Gaz is right! In fact you never take us to your house! Why is that?"

Ally shifted her eyes for a few seconds then smiled at her friends. "Oh well, my house is a very boring place. You wouldn't like it at all."

"Oh...."

(After school)

Zim and Dib already left the school walking home while arguing AGAIN as Ally, Tak, and Gaz were walking together for a while.

"Its still hard to believe that you have a job." Tak said lazily.

"Yeah well I wanted to make some money to get myself some tasty snacks and video games too." Ally smiled.

"Does your parents know that you got a job?" said Gaz

"Yeah."

"Where do you work anyway?" Tak asked.

Ally laughed. "Sorry but that will have to be kept a secret."

Gaz and Tak gave looks of disappointment. "Why?"

"Because if you know the answer it will really shock you!"

Ally checked her wristwatch and gasped. "Oh dear, I got to go! Bye girls! Oh and Gaz, I think you should go with Zim to the dance!"

"WHAT?" Gaz shouted with suprise.

"Uh huh! And Tak should go with Dib! Later!"

Tak didnt say or do anything.....she just stood there shocked.
