I've been doing a lot of Invader Zim fanfictions lately and decided to do something new. So, here's a Secret Saturday's fanfiction! This is placed after Zak Monday lost his powers. I know there wasn't any time gap between that and the season finale, but I decided to put it up anyway. Hope you enjoy!

*Zak* Yeah, let's get going already. -has popcorn-
*me* oh brother...

Zack gasped as his evil counterpart, Zack Monday, tumbled into the airship's hold. His mom and dad had gone missing and made the airship stay in place, so Zack was stuck in midair with Fiskerton and Komodo. Although, they were on the bridge while Zack found himself stuck with the Monday boy in the hold. Zack hummed in thought. Reality wasn't bending out of control, he guessed it was because now that this Zack wasn't Kur anymore and they weren't exactly the same anymore that they weren't able to bend reality. Zack took out his claw and gave a warning look as Zack Monday stood up. His legs shook and he gave Zack a look of someone who could barely stand.

He nearly fell over and Zack found himself at his counter-part's side helping him up. Zack laid Monday's arm over his shoulders and helped him out of the hold and into the airship where the air pressure was normal. The door shut behind them without a sound as they walked into the hallway. Zak allowed Monday to lean up against the wall. Without his claw, and being as weak as he was, the Monday boy wasn't a threat at the moment. But Zak was still on guard just in case. His claw hung from his belt as he looked Monday over. He blinked. Monday turned a bit pale and groaned.

"I don't feel, so good," he said. In an instant Zak had helped his counter-part over to a trashcan, where he proceeded to throw up. Zak couldn't watch, if he did he'd throw up too and that wouldn't be good. Once the noise stopped Zak looked over. Zak sighed and put Monday's arm over his shoulder's again. Monday allowed Zak to hold up the weight he could not carry and forced his legs to hold up some, not wanting to crush Zak.

"Come on," Zak said and led him down the hall. Neither one spoke as they walked down the hallways of the airship to Zak's room. Even though he didn't like who he was helping and really didn't want to help him in the first place, Zak decided that he at least deserved a chance. He seemed pretty shaken from the whole Argost-took-the-Kur-powers thing. Monday sat on the bed and rubbed his head with a groan. "You should get some rest, I'll let Fisk and Komodo know you're here. Oh, and if you cause any trouble while you're here, I will rip you to shreds." Monday smiled a bit and nodded.

"Of course I wont cause any trouble, I dont have the strength to anyway," Monday said. Zak muttered something to himself and headed to the bridge. He didn't like the idea of having his anti-self hanging around with him. But he couldn't just throw him off the airship. Zak stopped. How did he get on there anyway? Zak started to walk again, but was now more tense. If Monday tried anything, he would skin him alive!

...

Zak sat in the captain's chair and heard the door hiss open. He didn't look over. He could tell my Komodo's warning hiss and Firskerton's light growl that it was the Monday boy. He had been since noon and Zak was getting more and more uncomfortable with this. Monday leaned up against the back of the chair and Zak had to use all his will power to look up at him. He was unsurprised to see that he was not looking back. But instead out the window at the clouds. He hummed in thought and looked down at Zak, as if he felt his eyes peering at him. Both boys merely stared at each other, as if a silence conversation was going on between the two. Fiskerton gave a confused mutter. Monday pushed off from the back of the chair and smirked.

"So, are we just going to sit here or are we going to have some fun?" he asked. Zak stood up and turned to Monday, arms crossed and a serious look spread across his face.

"Depends on what you think fun is," Zak asked. Monday chuckled in a kind way. Zak personally would've preferred he did it the creepy way. Him being nice was sending shivers down his spine, and he didn't like it one bit.

"Well, it's your airship. So, what do you want to do?" Monday asked with a shrug. Zak shrugged back and walked out of the bridge with Monday right behind. Neither one spoke as they thought of something to do. In truth, Zak wanted to go crazy but didn't want to have his parents come back from being missing and suddenly be mad at him. He really didn't need that right now. Not with the whole Argost-is-now-Kur thing. Zak sighed inside his head. He didn't know what to do, he needed to find something to take his mind off of all this, but what? Without knowing he was doing it Zak's head hung a bit and his shoulder's slumped. Monday put a hand on his shoulder and turned him to face him with a friendly smile. "Come on, you look like you need to forget the world for awhile."

...

Zak laughed as water splashed all over Monday. Monday smirked and shoved Zak into the river. Zak yelped in surprise and glared up at his counter-part, who was grinning down at him. Zak grabbed his arm with both hands and pulled him the water next to him. Both looked at each other and laughed again. Luckily Monday was able to figure out how to drive the airship, and finding the river was easy. Monday stood up and helped Zak to his feet. Zak kicked the water, sending a spray of water onto Monday. The look of surprise on his face sent Zak into laughter. Monday smirked.

"So, you wanna play hardball, huh?" Monday said sending an even bigger spray of water onto Zak. Zak gasped in surprise and gave Monday a glare.

"Why you little!" Monday let out a scream as Zak chased after him. The scream turned into laughter as he afaided him with ease. Zak let out a yell of surprise as he tripped and fell onto Monday. Both started laughing within seconds and Zak helped him up off the ground. They hadn't stopped laughing. Fisk and Komodo walked out and Fisk tilted his head at them. Monday shoved Zak in a friendly way and Zak shoved back. "You're insane!"

"I am you're counter-part!" Monday teased. Zak smiled and shoved him again. Monday grabbed Zak in a headlock and rubbed his fist roughly against his hair. Zak tried to pull out of his grasp and Monday merely laughed in amusment.

"Ah! No, stop! Stop it! Lemme go! Leggo! Leggo!" Zak shouted. Monday finally let go and Zak shoved Monday so hard he stumbled backward, tripped over a tree root, and bumped his head on the tree behind him. Both went silent a moment, but then continued laughing. Fisk made a noise and they both looked over. "Oh, hey Fisk. What's up?" Fisk and Komodo looked at each other in puzzlement. Monday smirked.

"Race ya to the bridge Zak!" Monday shouted running into the airship.

"Hey, no fair!" Zak yelled running after him as he laughed back at his counter-part. Fisk and Komodo followed them and closed the hatch. Monday ran onto the bridge and turned to gloat only to find himself tackled by Zak. Both laughed and Fisk merely scratched his head. Why these two were getting along puzzled him more than ever. They stood up and shoved each other playfully as they laughed at each other. Fisk looked back down at Komodo, who simply walked over to Monday and let out a funny growl. Both boys smiled down at him. Fisk smiled a bit. Zak did need to hang out with someone his age.

...

Zak screamed as the roof of the building he stood on caved out from under him. Drew screamed out his name and Doyle held her back so that she didn't get crushed by the falling building. Drew protested and pulled on her brother's grasp as he held her back. Doyle watched in horror as Zak fell down with the rubble and disappeared behind all the bone crushing rocks. Drew stopped pulling as the building stopped collapsing and there was silence as they stared at where the building had once stood. Doc walked over to Doyle's side and nodded for him to release his wife. Doyle let his grip go and Drew ran over to the pile of stone.

"Zak!" Drew called and ran towards the rubble that had once been a rundown building. She stood in the midst of the rubble and looked all around, calling out his name and moving over rocks. But Zak was not to be found. She fell to her knees and put her hands over her eyes as tears spilled out. Doc walked over and put a hand on her shoulder. Drew looked up at him. She stood up and held tight to him as she shed tears for her lost son. Doyle stood a few paces away from them and looked all around him without saying a word or even giving expression. This couldn't be happening, Zak couldn't be dead, but there was no way he survived that.

"Mom! Dad! Uncle Doyle!" All three looked over to see Zak standing on top of a large rock waving at them. Doc and Drew ran over to him.

"Zak!" Drew yelled as they both wrapped him up in their arms. Doyle smiled. He knew that Zak was going to be fine, there was no way he was no way he was going to let a bunch of rocks get the better of him. Drew looked at Zak in question. "But, how where you not crushed by the rocks?" Zak looked at them, confused.

"What are you talking about? I was nowhere near here, I was - oh no," Zak ran away from them and his breathing quickened. They watched in confusion at Zak. "No, he did not just - M.D? M.D!" There was on response. Zak's shoulder's slumped and he shook his head. "This isn't happening, no! M.D! M.D!"

"What!" Zak looked over as Monday pushed himself out from between two rocks and wiped himself off. "I'm right here, geez. Whoa." Zak tackled his friend to the ground and smiled.

"Don't do that again, ok?" Monday smirked and shoved Zak off of him, he muttered an agreement and both boys stood up. Zak grabbed Monday's arm and dragged him out to meet the others. They all backed away and gave Zak a questioning look. "You guys all know M.D. You know my mom and dad, and that's my uncle Doyle." Monday nodded.

"M.D?" Doyle asked with a raised eyebrow. Zak smirked.

"Yeah, for Monday," Zak told him. Monday rolled his eyes. "What? It would be weird if I called you Zak." Monday shrugged a bit and shoved Zak. Zak shoved back and ran. "Race you to the airship!" Monday smirked and ran after Zak. Doc, Drew, and Doyle followed behind. They had to keep up because they had no clue where they airship was. Both boys were yelling something at each other and Zak tripped over onto Monday. Both lay on the ground laughing afterwards. Doc and Drew gave each other a smirk. It seemed they had an addition to the family.

There will be one more short chapter after this, but that's it. Why? Because my sister told me I had too.

*Zak* um, why are you doing what you're sister says?
*me* because she's my little sister and I love her. Anyway, please review!
