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.

A/N - Maybe I should make a special note: All of the chapters are connected and is in order. Just in case you think the chapters are separate, but they're not. There are all connected and it's in order, just in case you need to know.

Everything was pitch-black and pure emptiness... until a bright light appeared as Zim slowly opened his eyes and stared at the roof, until a white-haired girl comes up to his face, catching him off guard.

"Ahhhhhhhh!" Zim screamed as he falls out of his bed carelessly and onto the floor.

The girl simply tilts her head innocently as she gets up from her chair, walking towards the irken and kneels down as she stares down at Zim. He growls as he looks up with an annoyed face until his eyes widen in surprise.

The girl has short, wavy and white hair with full bangs, closed eyes and pale skin. Her facial features are exactly like Hana's and Lily's and wear the same cape as Hana had, except it's black.

"..." Zim stayed silent as he still keeps an annoyed face, "More Gaz's lookalikes! Seriously! First, Hana-unit, then Lily-stink and finally her! Come on Earth! Stop being so cruel to Zim for fuck's sake and it's bad enough I killed off seven other Alter units who looks like fucking Gaz!" "Umm...who are you?"

The girl didn't respond, instead, she stares at Zim with her closed eyes, making Zim rolls his eyes.

"She can't speak yet, dumbass," Tori told him where she is sitting in a wooden chair, "You know damn well Alter units couldn't speak due to how they were created until they formed a close bond with a certain someone, right?"

"...She's an Alter unit too huh?" Zim muttered, and then he remembered something, "Wait! Hana-unit! Is she-"

"Sorry bro, but she's gone into the underworld like 'bye bye bitches'," Tori answered him, making him looks away, "Relax, she's an Alter unit, she can easily survive being in the underworld, since her body is simply created to survive the underworld, especially the fog."

"...What about her?" Zim asked about the white-haired girl.

"Oh shit, I forgot to introduce her, sorry," Tori apologised to both her adopted brother and the Alter unit, "This is Alter Unit number two-Drei. Do you want to wave your hand to your new friend, Zim?"

Then the girl named Drei waved her hand as she then picks up some notebook and starts writing, making Zim sit up and stare at the white-haired Alter unit. She finished writing and gives the note to him, where it says; 'I hope we can be friends'

"...Bah!" Zim shrugged off as he crunches the paper and throws it away, "Zim doesn't need friends! Keep that in mind Zim is only interested in revenge, nothing more, nothing less, got it?"

"..." Drei looks down in sadness and nods, making Tori grabs a newspaper with an angry expression, rolls the paper up, went up to Zim and hits his head with it.

"Hey! How dare you hit the almighty Zim!?" Zim snapped at his adoptive younger sister, until she does it again, "Oi!"

"That's for being an asshole, Zim!" Tori told him off, "And you're such a liar! If you really don't care about having friends, then fucking tell me why you give a shit about Hana, why do you put up with Harumi, Gir and everyone else, and why did you save Lily from getting killed!"

"...How did you-"

"Aezira told me when I got to the clinic," Tori answered his question, "Now answer MY damn question!"

Zim looks away again, not knowing how to answer her question, except "I...I don't know..."

"...Wha?"

"...Ever since I was taken in by your human mother...my...my body isn't the only thing that's going through changes..." Zim responded unsurely, "...I...I don't know how to say it, but I felt like something is overwriting my personality...something...I...I can't explain it properly..."

"...That is quite odd," Tori agreed with him. "Hey Drei, you okay?"

Drei nodded, making the scientist sighed of relief, "Good...oh yeah, Zim I need your opinion on a theory I came up,"

"And that theory is?"

"Well, so you know the last words of the Alter units you killed before?"

"...'Zim' if I remember correctly," He answered her.

"And do you remember what's Hana's first word?"

"...Zim..."

"In that case, if Drei's first word happens to be 'Zim' as well, then it proves my theory," Tori said, "It would prove that the Alter units...are all strongly connected to Gaz Membrane, Dib's long-lost younger sister."

"What the fuck!" Zim shouted as he quickly gets up and grabs her by the collar, "You better be fucking joking or I swear I will fucking wreck this place!"

"It's the fucking truth!" Tori shouted back, "I mean, the fact their first words is your name and the fact they look like Gaz in one way or another where they are strongly connected to her is the only explanation. After all, you mentioned you were close with Gaz during the second and third year of your time on Earth, right?"

Zim calms down as he lets go of Tori and sighs, "Yes...that is correct...I...there was that one moment that sticks out...when I waited for her at midnight and she sneaks out of the house to meet up with me..."
