Re-activating the heart

(A/N Hello everyone, I'm mrthunderkid and I'm a guy who loves to write harem fics and such. But today, I wanted to write the first ever Robot boy X Mlaatr fic. Believe me, I'm sure that not a lot of people have an interest for this and I can't blame them since they're both really old cartoons. But I loved watching them every Saturday. Hopefully this can appeal to everyone and people can go back and watch both of these series if they like this story. Anyways, please enjoy this little preview of my upcoming work and I hope you enjoy.)

"Oh man, of all the time for the Clusters to attack. But now I can finally get home and get ready for school!" Said Jenny as she was flying towards her house. She was busy all morning since the Clusters were attacking the Earth. The Clusters were the enemy robot race that Jenny had to take on but she always came out on top. As she was flying, her scanners began alerting her. She looked down at the forest to see something blinking.

"What the?" said Jenny as she flew down to see what it was. She carried on walking until she noticed the source of the light. In front of her was a doll sized robot whose eyes were glowing blue and red. The tiny doll also had a little orange watch which was also blinking.

"Hello, what are you? Whatever you are, you sure look cute." said Jenny as she went over and picked up the tiny robot. She then quickly started scanning it to see if it had any damages but other than a few scratches on the outside, it was perfectly fine. But she was surprised that it was so well made and built.

"Whoa, odd to find such a thing here of all places. Maybe mom can fix you up." Said Jenny as she picked up the tiny robot and flew towards her house.

Jenny's home

She then flew down in front of her house and quickly wiped away all the dirt on her clothes. She then took out the little robot and quickly wiped away all the dirt on it. She then opened the door and walked in to see her mother reading the newspaper and while enjoying her morning coffee.

"Mom!" said Jenny as she flew over to her creator and hugged her. Her actual creator, her name was Dr. Noreen Nora Wakeman. She was an elderly robotics scientist and the one who built XJ-9 (Jenny). She considered Jenny her actual daughter and would do her best to take care of her. She'll often butt into Jenny's personal life and call during the most awkward moments. She was that stereotypical embarrassing parent.

"Good morning, XJ-9. Was your mission successful?" asked Nora as she put down her coffee and turned to her daughter.

"Yep, the I made sure to teach those Clusters a lesson to make sure that they never mess with our planet ever again! But it's really getting annoying since this is the third time they attacked." said Jenny with pride.

"That's good but I'm sure that you can take care of them again if they arrive. Now hurry up and get ready or else you will be late for school." Said Nora as she turned to her paper again.

"Uh mom, I was wondering if you can have a look at something for me." Said Jenny as she took out the tiny robot doll. Nora then turned back to her daughter and saw the doll that she was holding.

"XJ-9, what is that?" asked Nora as she went over to her daughter to inspect the doll. He saw the tiny doll which looked as if it was 30 cm and with blue hands and legs.

"I'm not entirely sure. I found it on my way back. I noticed that it was blinking but other than that, it did nothing else. I did a scan on it and it's really well built." Said Jenny as she gave her mother the tiny doll. Nora then started inspecting the doll and saw its design. Normally she wouldn't be interest in such things but this immediately caught her eye.

"Well this is definitely extraordinary, I have never seen such a thing before. Quite well crafted as well." Said Nora as she took the tiny doll and started shaking its hand. She then took a closer look at the watch that was stuck on its arm.

"Well, do you think that you can fix it?" asked Jenny as she grabbed her bag.

"Well of course, I will begin immediately. But you should get ready for school!" said Nora as she was still inspecting the doll.

"Sure mom, I'll see ya later." Said Jenny as she got out her rocket skates and rode off to school.

"Now then, to see what you are made of." Said Nora as she went down to her lab with the tiny doll.

A few hours later

"Man, that test was bogus. How was I supposed to study when aliens were threatening the planet?" asked Brad. Brad is Jenny's human friend with apricot-coloured skin, spikey red hair and dark-coloured eyes. He wore a white dress shirt with a blank vest over it, khaki pants, and black dress shoes. He was feeling sour over his C minus.

"Aw come on Brad, the test wasn't that bad. Well if you studied." Replied Jenny as she was holding her paper with an +A.

"Easy for you to say, your head is pretty much the internet. You could've answered those questions with ease." Said Brad.

"Well, those are the pros of being a super robot." Said Jenny with pride.

"Yeah, but that's not fair Jenny. I wish that I was a super cool robot that could cheat on her test." Said Tucker who was playing on his yoyo. Tucker was Brad's younger brother. He would occasionally tag with Brad and Jenny to go on adventures with them but his aptitude for adventure was significantly less than Brad's. He had black hair while wearing a red shirt with a black stripe in the middle. He also wore blue pants with tiny blank shoes.

The three were walking home but then Jenny's pony tails started moving by themselves. This was her alert signal to let her know that danger was approaching.

"What is it?" asked Brad. Jenny then brought out her screen from her stomach to see that the same aliens had begun to attack again.

"Aw come on, I defeated them this morning. And this time they brought their leader." Said Jenny with annoyance. She then quickly unlocked her jet packs and got ready to take off.

"Listen Brad, can you do me a favour and let my mom know that I'll be a bit late today?" Requested Jenny.

"You got it! Come on Tuck!" said Brad as he started rushing towards Jenny's house.

"Wait for me, Brad!" said Tucker as he started running after his brother.

Jenny then flew at top speed towards space to take on the Clusters. Jenny had no issues taking on her enemies since she was always fighting things even stronger than them. But little did she know that this time was going to be different.

"(Just get to space and defeat the aliens. It will be easy.)" thought Jenny as she carried on flying but just as she arrived, she looked over to what she was about to face. And their numbers were over 9000! (Sorry had to). Kidding, it was only 200 ships.

Inside the command ship

"Have you found her?" asked a female robot through a screen.

"Indeed my queen, she has appeared in front of our sensors. Should we begin the assault?" asked a robot who was wearing a Navy outfit. He had a few medal on his chest and wore a captain hat.

"No! I want her alive! She will be a helpful tool in our conquest for the galaxy. So do not destroy her!" said the Queen.

"Understood, my queen." Said The General as he shut off the transmission. He then turned over to his console and press a button which activated the ship's weapon system and alerted all the other ships.

"Get the weapons ready. We must make sure that she is brought to the queen!" said the general.

Outside the ship

All of the ships then took out their weapons such as their rockets, lasers and the tractor beams. Jenny just watched as all of the ships then pointed their weapons towards her.

"Or not. I'm gonna be here for a while." Said Jenny as she was overwhelmed by the number of space ships in front of her.

Jenny's home

Brad and Tucker then quickly reached Nora's house and started knocking like crazy to get her attention but Nora wasn't opening the door at all. He then noticed that the door was actually open and went inside.

"Um, Misses Wakeman?" asked Brad as he was trying to look around but then he noticed that no one was around. They looked around but the place was empty and barely had any light in it.

"Is it just me or does this place feel haunted?" asked Tucker as he was shivering. Brad just rolled his eyes after listening to his stupid idea.

"Tuck, there is no way that this place is haunted. But where is Misses Wakema…" said Brad until he started hearing a noise. They looked over to the basement and heard a noise from it.

The two then went inside to see if they could find her but with no luck until he started hearing some noises.

"Uh….. Misses Wakeman?" asked Brad as he carried on walking down stairs. The room was so dark but they were able to notice that Nora was working hard on the tiny doll that Jenny brought in.

"Absolutely amazing, I have never seen such a fascinating design before. The only person I know that can create such a robot is… Brad, Tuck?" asked Nora as she looked over to the door to see Jenny's friend.

"Misses Wakeman, hi there." Said Brad as he walked in to greet Nora. He then looked down to see the tiny doll on the work desk.

"Wow, are you creating a baby brother for Jenny?" asked Tucker as he saw the tiny robot doll.

"No Tucker, I am not. I was trying to fix this robot that Jenny brought me this morning." Said Nora as she was working on her computer. Brad looked over to the computer screen to see the tiny doll but then it started transforming into different forms. There was the deactivated form, activated form and the Super activated form.

"I have to say, I have never seen such a well-designed robot. The weapons and technology is absolutely fascinating! This robot is definitely capable of taking on XJ-9, it even has a superior modelled program. Capable of super strength, durability, speed and even flight. To think that it was crafted with Vibranium, absolutely fascinating! The only problem was the limited power supply. I mean really, who would power up a super robot with AA batteries? Luckily I was able to install a new power source which is self-charging and long lasting. Which reminds me, why are you two here?" asked Nora.

"Oh yeah, we came here to tell you that Jenny's gonna be a bit late. She's off to fight the Clusters that are coming to invade the earth in outer space." Said Brad.

"I see, well if that is all you have to say then I would suggest that you two leave immediately!" said Nora as she was about to get back to work.

"This thing is so cool!" said Tucker as he started moving the tiny Robot doll like an action figure.

"TUCKER! PUT THAT DOWN! I have worked all morning to fix that robot and I will not have you mess it up!" scolded Nora as she was about to get Tucker but then, all the computers started going crazy as the alert was on high.

"What's going on?" asked Brad as he was surprised at the alert signal.

"It is the emergency XJ-9 alert, this only triggers when XJ-9 is in critical condition. She's in danger!" said Nora as she started working on the computer. She then used her computer to hack into the satellite to see the footage of what was happening. She then saw the Cluster ships gathered together as they were firing at a damaged Jenny.

Jenny was doing her best to dodge all the aliens as they were firing towards her. She had already taken heavy damage but she was still trying to fight back. She quickly got out her rockets and started firing towards the alien ships but then they quickly brought out their reflector shield to block her attacks.

"This isn't working! I can't dodge and attack at the same time." Said Jenny as she was doing her best to dodge all the Cluster weapons. The general's ships then finally used their tractor beam and stopped Jenny causing her to freeze in place.

"Oh crud! I'm trapped!" said Jenny as she couldn't move.

Inside the ship

"Good news captain! We successfully captured the robot!" said one of the soldiers.

"Good, Queen Vexus will be most pleased. But a little project will not be a problem, fire the lasers!" Said the General.

"B-but Queen Vexus said she wanted her alive!" said the Soldier but then the General turned to the soldier with an angry glare. The soldier quickly backed off and nodded as he went over to the console and started firing the laser at Jenny.

"AAAHHHH!" screamed Jenny as she could feel herself burning.

Jenny's home

"No! Jenny's in trouble!" said Tucker.

"Can't we do anything?" asked Brad in a panic.

"I-I don't know! There is no way that we can reach her in time! Even if I activate the other XJ models, they cannot reach her in time!" said Nora in a panic.

"NO! JENNY!" screamed Brad as he saw his friend getting burned by the lasers.

Tucker shivering as he was watching the screen but then hand accidently landed on the watch that was on the robot. Tucker then felt the tiny robot move and quickly dropped it. He then turned over to see the tiny robot grow bigger. The robot itself grew into 45 cm and the blue circles on its head, extended itself to become its ears.

"B-Brad….." said Tucker as he was trying to get his brothers attention.

"Not now Tuck!" said Brad.

The tiny blue robot then started blinking as its eyes were glowing blue. He then started looking around and started scanning its surroundings. He had no idea where he was or what was going on. He then carried on looking around until the screen grabbed his attention. He saw the footage of Jenny getting zapped by the Cluster ships and her screaming in pain.

"Can't we do anything Misses Wakeman?" asked Brad.

"I'm afraid….there is nothing we can do." Said Nora as she turned away. Brad then fell to his knees and started crying as he realised that he was about to lose his best friend.

"Brad!" said Tucker as he was still trying to get his attention.

"Not now Tucker! Can't you see I'm feeling bad about losing my best friend?!" asked Brad as he carried on crying.

The blue robot then turned to the humans and saw the humans who were feeling bad. He then turned over to the screen again and started calculating their location. One glance and he was able to tell where Jenny was.

"Robot boy! Will help!" said Robotboy as he activated his thrusters and flew straight through the roof. Nora, Brad and Tucker all felt the impact from Robot boy crashing through the roof.

"T-Tucker…. what was that?" asked Brad.

"And where is that tiny robot that you were playing with?" asked Nora.

"That was the tiny robot!" Said Tucker as he pointed at the holes through the roof.

They then turned over to the screen and saw that Robot boy had reached space in a split second.

"What the?! How did he get there so fast?" asked Tucker.

"Impossible! To reach space in such a short amount of time, he must've flew 299792458 miles per second!" said Nora. Brad and Tucker then turned over to Nora with confused looks as they had no idea what she meant. Nora simply sighed and responded.

"That is basically the speed of light." Said Nora.

"Oh!" said Tucker and Brad as they were nodding at what she said. They then turned over to the screen and saw Robot boy flying towards the alien army.

"But even so, what could that tiny robot do?" asked Brad.

Robot boy then saw the number of ships and calculated that there were exactly 200 ships. But the ships that were firing at Jenny were lined up together. Robot boy then flew even faster and punched one of the ships which caused the other ships to hit each other like a dominos. The ships then stopped firing and lost balance.

"What was that?!" questioned the General.

"We were attacked by an enemy robot sir!" said the soldier.

"What?! There were more robots?" asked the General. He then ran over to the screen and saw that it was Robot boy which punched the ships.

"What?! How could that tiny little robot do such a thing?!" asked the commander.

"We don't know! But it was definitely that robot!" said the soldier.

"Well then what are you waiting for?! FIRE AT THAT ROBOT!" yelled the General.

"Yes sir!" said the soldier as the other ships then pointed their weapons at Robot Boy.

"He's doomed!" screamed Tucker as they saw the aliens getting ready to fire at Robot Boy.

The aliens then started firing at Robot boy but then Robot boy simply back handed the lasers towards another ship. The General, soldiers, Brad, Tucker and Nora couldn't believe what they were seeing. The lasers that badly damaged Jenny was simply brushed off by Robot boy.

"H-how did he…." Said the soldier.

"RAPID FIRE!" screamed the General. The ships then started firing lasers at a rapid speed towards Robot boy but he simply deflected them with ease. Before he knew it, all the lasers were being sent back towards the enemy ships. Destroying them one by one! In a split second, their numbers decreased to 173.

"Sir, what do we do?! Our weapons have no effect!" said the Soldier.

"We don't have time for this! We must get the female robot to Queen Vexus! Tell every other ship to open fire at that tiny robot! I want it destroyed!" said the General.

"Yes sir!" said the Soldier as he went over to the console and started commanding the other ships to fire at Robot boy.

Robot Boy then turned over to see that Jenny was beginning to get pulled into the ship and quickly flew over to her. Robot boy then quickly blasted his hand towards Jenny and grabbed her foot. Once her foot was caught, he immediately started reeling her in to protect her.

"Sir! That tiny robot has stolen the female robot!" said the soldier.

"WHAT?! TELL THE OTHER SHIPS TO BEGIN FIRING! WE MUST GET HER BACK OR ELSE IT'S YOUR HEADS!" screamed the General.

The soldier then quickly gave the orders to the other ships and demanded that they started. Robot boy on the other hand then picked her up bridal style with his tiny hands and started scanning her body ( ͡° ͜ʖ ͡°). Turns out she was still functioning but her circuits were fried and needed immediate attention. Robot boy was getting ready to fly back with Jenny but then he turned to see that all the enemy ships were targeting both of them.

"FIRE!" screamed the General. The Clusters didn't even hold back. They used all the weapons that they had. Lasers and missiles were being fired at a rapid speed.

"NOOO! JENNY!" screamed Nora as she looked over to the screen. After the attacks were finished, all that was left was a smoke cloud and nothing was visible to them.

"Are they destroyed?" asked the General.

As the smoke finally began to fade away, they were finally able to see the two. But what they saw next completely shocked them. Robot boy was still protecting Jenny with his own reflector shield. Nora, Brad and Tucker couldn't believe what they were looking at. A tiny robot that had the power to deflect all of those attacks.

"Oh man…. that robot is awesome!" cheered Tucker.

"But even so, what can it do against an army of Clusters?" asked Nora.

"Guys look!" said Brad as he pointed at the screen.

Robot boy then simply let Jenny float for a second as he quickly turned over to the Clusters as his blue eyes started glowing red.

"My turn!" said Robot boy as he slammed his fists together. Just then, his body began extending as his parts started getting bigger. His ears got larger, his fists were bigger and his legs were fully armoured. His appearance had changed into a medium silver and darker hands, feet and taller blue ears. His face almost had a mask, with red outlining, and instead of eyes being blue, they were dark red.

"Time to finish this!" said Robot boy as he got his weapons ready.
