It was just another day at the Autobot base. No Decepticon activity had been pick up for awhile and Bumblebee and his team had come to visit from the scrap yard.

Sideswipe's twin brother Sunstreaker had come to Earth and the two of them had been pranking everyone none stop.

First they had put fake scraplets in the the main room and caused a panic. Then they put fake rust on Knock Out while the Austin Martin had been in recharge.

Sunstreaker and him had been arguing over who had the better paint job and this was the yellow sports car's way of getting one over on red medic.

But Sunstreaker and Sideswipe had both gotten a few dents over that one.

When they told Knock Out it had been a prank and the red sports car had promptly walked over to Ratchet's work staion and grab one of his wrenchs.

"Don't mess with my finish!" Knock Out yelled as he tossed the wrench and it hit Sunstreaker right in the helm and bounced off it and hit Sideswipe's then landed on the floor with a clang.

And Knock Out rubbed his servos together as if dusting them off.

"Knock Out!" Ratchet said as he walked over and picked his wrench up off the floor.

"Someone gonna get it." Sunstreaker whispered to his brother.

"How did you do that?" Ratchet asked actually sounding impressed.

"It's all in the wrist my friend." Knock Out explained. "Just toss it like a boomerang."

"If anything ever happens to me I pass the wrench throwing torch to you." Ratchet told Knock Out.

The twins snuck out of the room afraid that if Ratchet asked Knock Out to give him pointers they might use them for target practice.

Meanwhile Bumblebee was in the main room talking to the rest of the team. Everyone had had just about enough of being pranked by the Terror Twins.

"This morning Sideswipe and Sunstreaker filled my closet with paper snakes." Agent Fowler told him.

"And I woke up this morning only to discover my bed had been moved to the hanger while I was sleeping in it." DeAnn explained. "Starscream woke me up asking why I was there."

"Do you know how humiliating it is to have your guardian and a whole unit of NEST soldiers see you in a pink nighty and your bed head hair?" She added.

"And it probably didn't help when Pixel brought you some bunny slippers." Said Starscream.

"Well he thought he was helping." DeAnn replied as she petted the little red minicon on the helm.

"Well just look at what they did to me." Said Shayna who walk in wearing a pink and black bathing suit.

"I get up and take a shower then start to get dressed only to find all my clothes are gone except my swimsuit." She told them not sounding a bit happy. "I've been getting whistled at all day and I still don't know where they hid my normal clothes."

"Well don't ask me how they did it but they some how put Bulkhead in my bedroom while he was in recharge." Miko chimed in.

"Ratchet help me get him out by using the ground bridge." She added "But he kind of fell on Steeljaw when he came out the other side because he tripped trying not to break anything." "It was really funny."

"From your point of view." Steeljaw told her. "But I'm definitely going to feel that later."

"Their pranks are really getting out of hand." Strogarm added.

"I'll talk to them about it later." Said Bumblebee knowing that the team had to scout an energon mine and would be busy for the rest of the day.

Later after everyone had gone to the energon mine except for the Twins, Starscream and Knock Out.

Sideswipe and Sunstreaker were both bored and decided to try to think of a prank to pull on the two former Decepticons.

Then Sunstreaker got the idea to tamper with Knock Out's and Starscream's signals to make them show up as Decepticon signals again instead of Autobot signals which wouldn't show up on the scanner because it was only programed to pick up on Decepticon signals for safety reasons. To warn the team if one was near by.

Then they went to watch the security cameras that the team had set up around the base. Thinking it would be hilarious to watch Starscream and Knock Out both freak out and run in circles thinking there were Cons in the base when they were actually chasing and hiding from each other.

Meanwhile Knock Out was working in the medbay when he saw a Decepticon signal pop up.

"A Decepticon here?" He thought as he put a digit to his com-link. "This is Knock Out I think there's a Decepticon in here." He said before releasing his com-link wasn't working.

"I forgot the com-link are down under maintenance today." He reminded himself. "I'll have to go get someone to help me deal with the Con."

Then he went to the hallway. While at the sametime Starscream had spotted the signal and went to deal with the Decepticon as well.

But the signal seemed to be going in circles and Knock Out and Starscream both followed the signal and kept missing each other. Both completely unaware of the other's presence.

Then Knock Out got scared and ran to the basement to hide. And Starscream saw the signal traveling to the basement and went after it.

The twins continued to watch from the cameras thinking it was funny. Until they saw Knock Out activate his saw while crouching behind some energon crates.

And on another camera they saw Starscream ready his claws. They hadn't counted on the possibility that Starscream and Knock Out might actually attack each other they were supposed to just run scared.

But now both mechs were ready to fight the Decepticon who they didn't know was actually their best friend. And were in the basement where it was dark and they might not recognize each other until it was too late.

Both Sideswipe and Sunstreaker rushed out of the room hoping to make it to the basement before Starscream made it down the stairs. And stop their friends from hurting each other.

This wasn't how the prank was supposed to go out all. How had this suddenly gone so wrong?

Upon reaching the top of the stairs that lead to the basement they heard screams then. "CRAAASH!!!

They both rushed down the stairs now seriously worried.

The quickly flipped on the light switch upon entering the basement. Only to be greeted with the sight of both mechs on the floor.

Knock Out was on top of Starscream apparently Knock Out thought the Con was closing in on him and jumped the seeker in self-defense not knowing it was Starscream.

And Starscream had only known something tackled him and the two had fallen to the floor.

Sideswipe and Sunstreaker quickly ran over to help them up. And were horrified to see spilled energon on the floor below the two mechs.

And they saw that Starscream had a gash across his shoulder where Knock Out's saw hit him and part of his wing had been cut and was now hanging by only a few wires.

"Knock Out?!" The seeker whimpered in surprise looking at the cherry medic who was on top of him.

Knock Out just staired at the seeker with wide optics. "Star...sscream?!" The medic choked out then went silent as his optics rolled shut.

Then Starscream looked down with an expression of horror as he saw he had stabbed his best friend through the midsection with his claws and his servos were now covered in the red medic's energon.

"No!" Starscream cried seeing Knock Out's blood was laterally on his hands. Starscream stood there in shock trying to process what just happened.

Sideswipe ran off to get Ratchet luckily the rest of the team had just gotten back. While Sunstreaker just stood there in shock that prank had been his idea and he hadn't expected this to happen.

Starscream and Knock Out were both hurt. Knock Out possibly dying and he could tell Starscream had been traumatized. If they weren't ok he never forgive himself.

They rushed both mechs to the medbay where Ratchet got to work Starscream had told him to treat Knock Out first which he didn't argue with because Knock Out's injury was more life threatening Starscream had hit his main fuel line and the Austin Martin was bleeding out.

And Starscream's wing had been seriously damaged. But right now he was more worried about his friend.

The seeker just staired with a saddened expression on his face what if his best friend was dying by his hand. He just look down at his servo that was still stained with Knock Out's energon and cried coolant tears.

Sunstreaker just set there in shock looking just as devastated as Starscream did. And Sideswipe went over to his brother.

"What did we do?" Sunstreaker said sadly.

To Be Continued.
