The Friendship Contract

Destructive Homework

It was late at night and Mandark piloted his mecha towards Dexter's house. No one stirred in the sleepy neighborhood while he ventured over to the other's place. It was an odd but fortunate fact that no one noticed when things out of the norm happened in their neighborhood. Things that were caused by Mandark, Dexter or Dee. Those three however always recognized strange happenings.

"Why am I conducting my scheme so late at night? Why? Of course! Because everyone is asleep during this time so I can strike!" Mandark explained to no one in particular while nosily making his way to his rival's place.

Once there, Mandark controlled one of the robotic arms of his mecha to turn into a giant fist and he struck said fist into the window of Dexter's bedroom, shattering the glass. "I know you're in there, Dexter. You want to know how I know? Because it is nighttime and the weak sleep at night!" he blurted out through an intercom microphone in his mecha.

While Mandark had been making his destructive way to Dexter's house, Dexter had been hauled up in his laboratory doing a strange habit of his. That habit was unscrewing and screwing a bolt into a chunk of metal with a giant wrench. Was it meant to calm him down in some way? No one really knew why he always did that.

He quirked a brow and placed his wrench down gently after he heard a large crash occur inside of his bedroom. "That infernal Dee Dee. Destroying my bedroom just so she can enter my laboratory. Why she is up this late at night escapes my great mind," he muttered and hopped off from his swivel chair and marched out from his secret lab.

Once outside of his lab, Dexter noticed a familiar pincered claw lodged inside of his bedroom window...well, broken bedroom window. In an overly dramatic way, Dexter held up a pointer finger towards the direction of Mandark's mecha. "Mandark! Don't you have a curfew or something? Why are you here this late at night?" he shouted at the other genius.

While Dexter had been preoccupied in his lab, Mandark wondered why he did not get an instant reaction from him. "Are my speakers not functioning correctly?" he pondered and checked his intercom system. While he was doing so, he heard a familiar voice shouting hysterically at him. "Ah, so you are awake!" he noticed after glancing downwards and seeing a rather harried looking Dexter.

"Of course I am awake, who could sleep through that noise?" Dexter barked and shivered gently when a bitter gust of wind blew inside of his bedroom through the demolished window.

"Let me think about that one. The entire neighborhood, duh."

A scowl adorned Dexter's face and he motioned to himself, "Well, I am not the entire neighborhood."

Mandark blinked and chuckled. "You need to work on your witty retorts, Dexter."

"You are here...because?" the other replied in an exasperated voice and massaged at his forehead to keep his approaching headache away.

The brunette deployed a ramp from the midsection of his mecha and descended it...well, attempted to. The wind blowing dramatically behind him decided to mess around with his cloak. It got caught underneath a foot and so he ended up falling down the rest of the ramp. He landed face first in front of the other genius.

"That fashion statement of yours is a hazard to your health," Dexter said while Mandark struggled to stand up.

"Oh, I am fine. Thanks for asking," Mandark seethed and dusted himself off.

Dexter rummaged through one of his lab coat pockets and brandished the chunk of metal with the screw in it and tossed it towards Mandark. "Sorry I have not created something worth stealing yet, Mandark. Just take this."

"Hey! I caught it!" the other cheered with a beaming face.

"Yeah, congrats. Now please leave."

"I did not come here for this piece of junk. Just like you are, Dexter. A piece of junk!" Mandark hissed and with a random surge of strength, he managed to toss the chunk of metal carelessly behind him.

"Ouch, that comment really hurts me," Dexter replied with obvious sarcasm.

Before Mandark had a chance to brandish a retort, he heard his mecha starting up on its own. He would have pondered this strange new development but he was not given the chance to because the ramp that was still deployed from the mecha went swooshing dangerously close to him after it had raised up.

"Argh, no! I need my head!" he screamed while the ramp inched nearer.

"You idiot! You managed to turn on the autopilot!" Dexter replied and pounced onto Mandark since his reaction time was not as lame as the brunette's.

They both watched as the mecha destroyed more of Dexter's house with the swinging ramp. It turned around and ventured down the neighborhood. Both remained in shock for a few moments until they decided that nothing could be solved by just being in questionable positions.

"I guess when I threw that worthless piece of junk, it somehow managed to lower the lever for the autopilot," Mandark mused while shoving Dexter violently off of him.

"Well I hope you know that this is your fault. I want nothing. I repeat, nothing! To do with this," Dexter replied and stood up with a barely visible blush on his face.

Mandark retired from the floor and straightened his clothing and glasses. After that he turned towards the demolished wall of Dexter's bedroom. "Ah, no. It is your fault," he corrected in a matter of fact tone while watching the fading image of his mecha.

Dexter's blue eyes narrowed dangerously and he silently brought one of Mandark's arms behind his back in a painful way. "Oh hey, I got an idea. You admit that this is your fault and I will help you to get your mecha back. Hm, or I will push you out of my bedroom," he whispered to him and ushered him towards the edge of his bedroom.

"Okay, fine! It's my fault now stop creeping me out!" Mandark cried while trying to not look down.

"I am just not someone to mess with once in awhile," Dexter explained and released Mandark.

"Well, how do you propose we go about retrieving my mecha?" he asked while rubbing violently at his arm that had previously been in the red head's possession.

"Well, do you have some sort of tracker?"

"Yes, I do. However, it is not currently with me," Mandark answered in an embarrassed whisper.

Dexter kept his cool and calm composure. Not allowing the other's sentence to be the wrecking ball against the building. Not a crack. Not a scratch. "Okay. No problem. Follow me to my lab," he replied calmly and withdrew from Mandark's side.

Mandark did just that. Not the least bit in the mood to get himself into another wrestling move with a pissy Dexter. He followed the other genius near a huge lit up space that had Dexter's own mecha stationed there but also...his?

"A replica, that is all. The outside is a perfect identical twin of your original, Mandark. However, I am sure the inside workings and such are different. I only know the design of the outside of your mecha anyways. Anyhow, I hope the differences inside of it will not hinder you too much," Dexter explained and entered his own mecha. Easier to cover more ground with two mechas.

"I know it's a replica. Pah, I hope it won't hinder you too much," Mandark grumbled in a childish manner to no one in particular and entered the replica.

"Hopefully we will not be looking for it the rest of the night and all early morning. I do sleep," the red head said while a huge section of the roof of his lab slid back to allow an exit for the two mechas to take.

Dexter could imagine Mandark rolling his eyes. "Please, it is near out of fuel and is running on the emergency backup supply. It will not be flying around or causing destruction anymore so shut your mouth," the brunette snapped and made an angry departure through the momentary exit.

"Well, someone has issues," Dexter muttered under his breath with a blush of slight irritation across his face. He soon departed after the other into the star marked night sky.

The two came across the pilot-less mecha a few ways after their neighborhood and into the local shopping areas. It was surrounded by mass amounts of rubble and debris.

"There it is!" Mandark announced and landed near it.

"Really? I thought it was a worm hole," Dexter replied sarcastically and manned his mecha to land a few ways off from the other two mechas.

Mandark withdrew from the replica mecha and returned to his own. There was enough of the EBS to take him back home. "Uh, Dexter. I actually had...well, do have a reason for why I disturbed you today...tonight, I mean," he started sheepishly.

"Einstein's ghost, Mandark! You do not need to correct yourself. I know what you mean."

"Well, it seems that my German homework is not finished. I think I might need help with it...from you," the other replied and brandished the worksheet with a mecha hand in front of the other's mecha so he would be able to see it.

"It's completely blank. Aside from your name," Dexter noticed with a slight tone of surprise.

"I know. I thought learning the language would be simple considering that it is somewhat like the English language. It just seems that perhaps I let my pride get the best of me...considering I never really pay attention to our teacher nor have I ever brought my textbook with me from school," Mandark explained in the same sheepish fashion.

Dexter smiled gently. "Sure, I will help you. Next time though, you could just call me or something."

Mandark laughed bitterly. "Yeah, like that will ever happen."

"A guy can dream, can't he?"

Author's Notes:

This probably would have been up sooner if I were not playing video games and watching random things on "The History Channel". HEHE!

So yeah...first chapter at my attempt at making a fan-fic with chapters.

This is inspired from an actual RP I had going on with one of my friends.

I changed quite a lot of things to add more humor and yada, yada.

Like with my one shots, the characters are much older. High school and so forth.

OH! I have some of my Mandark crossplay finished! Yeah, well...I am going to crossplay as the guy for a future anime convention. Apparently I picked an awesome character to crossplay as. Haha, my friends think I look sexy as him. I only have a few more things left to buy for it to be finished.

ANYWAYS! Let me know if anything in this chapter seems off for whatever reason. I am not meant to be an editor. Lawl.
