I really enjoyed the series Young Justice so I figured, why not do a story about it. This is a Connor/Cassie/Megan pairing, it may seem weird but I think I've tied it together nicely. There is a bit of everything, action, humor, and a bit of romance for those of you who enjoy that.

Disclaimer: All characters are owned by DC, the only thing i own it the plot and my OC's

Enjoy guys!:)


Chapter 1

New and Improved

June 20th, 2017 (One Year After Endgame)

Location: Mount Justice (Rebuilt)

7:00 p.m.

"Have you heard from Connor?" Artemis asked giving her little girl a bottle. Jade was born eight months after Wally died. Artemis had been pregnant for a month before they were in Paris that night. The little girl had orange hair and green eyes like Wally. Her face though, looked exactly like Artemis and she had slightly tanned skin.

"No I haven't" M'gann said sighing.

"Cassie and Connor have been getting really close lately. I know we aren't seeing each other, but it makes me mad just to see that. Robin has been upset too seeing as Cassie broke up with him" M'gann said. Artemis nodded and sighed.

"What's it been, like a month or something since he's been gone?" Artemis asked. M'gann nodded and allowed Jade to grab her finger. She smiled at the baby and they were interrupted when Nightwing came onto the communicator.

"Miss Martian and Artemis report to the briefing room" he said. They both sighed and made their way to the room. When they walked in everyone was sitting at the table. Nightwing was at the head of the table. Robin, Batgirl, Aqualad, Wonder Girl, Rocket, Blue Beetle, Lagoon Boy, Beast Boy, Static, Bumblebee, Guardian, and Impulse (Kid Flash now, but I'm just gonna call him Impulse) were seated at the rectangular table as well. The table sat 20 people even though they only had 16 members on the team. The two girls sat down and looked at Nightwing and he was typing something into the computer pad in front of him. At every seat there was a small computer pad built in and a hologram projector in the middle of it.

"So we're all here now" Kaldur said. Nightwing nodded and let out a long breath. A picture of Superboy popped up on the screen and everyone gave him a questioning look.

"One month ago Superboy found out about Star Labs being rebuilt" he said as a picture of the new building and Lex Luthor came onto the screen.

"Lex Luthor was overseeing a project there and Superboy went to investigate" he said showing an image of the facility blueprints. He made it a 3-D hologram and zoomed in to the basement. A dot appeared near an elevator door.

"This is the last place he was seen" he said sighing.

"Why are we just hearing about this now?" M'gann asked raising her voice. Nightwing hit a few buttons and a video recording came up. Nightwing pressed the pause button on the video and sighed.

"This was sent to me by Superboy a week after he went into Star Labs" he said playing it.

"Nightwing I'm not sure what the project is yet. I do know that it's something bad; I'm going to disable all comm links until I find out what's going on. Don't worry about me I'll be fine I just need to do this" he said before the video shut off.

"I don't like the sound of that" Beast Boy said.

"We have to go and get him" Artemis said.

"Not all of us can go, so we'll have to put together a team" Kaldur said.

"I'm already on that. Miss Martian, Aqualad, Beast Boy, Artemis, Wonder Girl, Lagoon Boy, Impulse, and I will go to Star Labs and get Superboy back, meet in the hangar in five" Nightwing said standing up, he turned and walked out of the room. Five minutes later everyone who was going was gathered in the hangar; they loaded up in the bio ship and took off.

"So what's the plan when we get down there?" Beast Boy asked.

"It's simple; Miss Martian will turn invisible and look around the building for him. When she finds him she gives us her location and we bust in and save him" Nightwing said. They put the bio ship in camouflage mode and hovered above the roof.

"Okay Miss Martian you're up" Nightwing said. She nodded and turned invisible and flew into the building.

"I'm the basement now" Miss Martian said through the mind link.

'Be careful Miss Martian' Nightwing said. She looked around until she found an elevator door. She went through it and down the shaft until she got to the ground floor. On the door it said B-105 in lard red letters. She went through the wall and put a hand over her mouth holding back a gasp. There was a boy being experimented on in a tube, machines were everywhere, doctors were all over the place, and there were other people being experimented on. She could hear screams of pain from the people.

"Are you guys seeing this?" she asked sending them mental images of everything.

"Yeah, it looks like we're going to have to save these people too" Nightwing said.

"Send Garfield down here, he can free the prisoners and I'll look for Connor" Megan said flying off to another part of the large room.

"Rodger that Miss M, sending Beast Boy now" Nightwing said. Miss Martian flew off and checked every room but couldn't find Superboy.

"Miss M, Beast Boy has secured the prisoners. We're just waiting on you" Nightwing said.

"I've searched everywhere and he's not here" Miss Martian said. She looked around one more time just in case, but still couldn't find him.

"Miss M, get back to the ship. We're going to pay Lex Luthor a little visit" Nightwing said. She smirked and flew back up to the roof. She got into the ship and they headed to Luthor Corp., when they got there they flew up to the top floor. When they got there they were not expecting to see Superman standing in the room with his arms crossed over his chest. The window was broken, obviously how he got in.

"Why did you want me here Luthor?" Superman asked in an annoyed voice.

"I was curious about my son" Lex said smirking. Superman closed his eyes and clenched his fists.

"So where is he?" Lex asked leaning back in his chair.

"He's somewhere where you can't touch him Luthor. You will never be able to hurt him like you did a month ago" Superman said.

"I never hurt him, all I did was give him a little boost" Lex said.

"You strapped him down and performed experiments on him!" Superman yelled smashing the table.

"Oh yes that, but in my defense I did help him out a lot. After all he now has all of his Kryptonian powers" Lex said smirking. The Teams eyes widened and they looked at each other. Superman didn't say anything he just hovered over Lex.

"Stay away from Kon-El or I will be back, and next time the window and the desk won't be the only thing broken" Superman said flying out of the room. He flew towards the bottom of the ship and it opened up and he flew in with his arms crossed over his chest and his eyes closed.

"I take it you came here to find Kon-El" he said. They all said yes and he sighed.

"Don't worry he's safe. I have him at the fortress, he's going through training right now" Superman said.

"What kind of training?" Nightwing asked.

"The same kind Jor-El put me through. He will return soon enough" Superman said.

Superman left and M'gann sighed, she turned her head and noticed a girl who looked to be about 19, and a boy who looked to be about 17. They were both wearing a tight white suit like the one they first found Superboy in. It clung to the girl's curves and busty chest tightly.

The girl had straight silky black hair that went just past her shoulders. She had light skin, but you could see that there was a slight tan. The boy had the same skin tone as her and his hair was exactly the same color. His hair was short and it looked just like Connor's. She recognized the boy as the one that was being experimented on in the lab.

"There were more people" she said looking at Beast Boy.

"I could only take two, and when I went back for more the guards were starting to surround me. I had to get out of there" he said. She nodded and ruffled his hair.

"You did well" Nightwing said. He nodded and sat down in his seat. They got back to Mount Justice and plopped down on the couch.

"Did you guys find him?" Robin asked.

"Well he's been with Superman this whole time doing training" Nightwing said typing on a computer.

"Well I'm leaving" La'gaan said heading for the zeta tube.

Recognized Superboy B04

Superboy stepped through the zeta tube and came face to face with La'gaan. Superboy had on a new outfit, but he still had on that same emotionless look. His new suit looked exactly like Superman's except it was black. The S symbol was exactly the same even the yellow behind the S. His cape and his boots were red, and he had on red fingerless gloves. They stared at each other for a few seconds and La'gaan clenched his fists and started walking away. Superboy smirked and walked past him. Ever since M'gann broke up with La'gaan he has hated Superboy even more. They heard the zeta tube go off and La'gaan was gone.

"Hey welcome back" Nightwing said still typing on the computer. After a few minutes of hugging and talking, Superboy walked over to Nightwing.

"Good to be back" Superboy said.

"Nightwing we have a mission for you" Batman said appearing on screen.

"What is it Batman?" Nightwing asked. The rest of the team surrounded the screen and a picture of Metropolis, Gotham, Star City, and Central City came up and there were a few red dots on them.

"Boom tubes have been activating all over Metropolis. The Justice League is handling them in other cities, but we need the team to go to Metropolis" Batman said.

"Alright we'll get right on it" Nightwing said before shutting off the video. Superboy looked around the room for a second and saw two new people he had never seen before.

"Who are they?" he asked.

"We found them at Star Labs. I think that at least two of us should stay here and watch them" Nightwing said.

"I agree" Kaldur said.

"Alright then who should stay?" Wonder Girl asked.

"I'll stay" Beast Boy said.

"Me too" Mal said. Everyone nodded and Nightwing pulled up a satellite photo of Metropolis. Four pictures came up and everyone's eyes widened. Bane was on one camera, a ton of Darkseid's soldiers were on another, Parasite and Mammoth were on another, and Deathstroke and Black Manta and his goons were on another.

"Okay Batgirl, Robin, and I will take care of Bane, we'll be Alpha squad. Superboy and Wonder Girl will take Mammoth and Parasite, you'll be Beta squad. Aqualad, and Blue Beetle will take on Deathstroke, Black Manta, and Manta's goons, you'll be Gamma squad. Miss Martian, Artemis, Impulse, Rocket, Bumblebee, and Static you will take care of the soldiers and try to save civilians, you'll be Zeta squad. Be safe everyone, and Superboy it's glad to have you back" Nightwing said. Everyone left and Superboy and Miss Martian started walking towards the zeta tubes.

"Connor" M'gann called out to him. He turned his head towards her.

"Please be careful, and I would like to talk after we get back" she said.

"I guess we can talk, and you be careful too M'gann" he said stepping through the zeta tube. She followed behind him and they ended up on a street in Metropolis. Buildings were smoking and people were screaming. The whole team was standing there and Nightwing turned around.

"You know what to do, save as many people as you can and beat the crap out of them. Miss Martian, link us up" he said before running off. All of the teams went off to their locations, Superboy was flying next to Wonder Girl and she looked worried.

"What's wrong?" he asked.

"I guess I'm just a little nervous. I've never faced anyone like Parasite before" she said.

"Don't worry I'll handle him. You take care of Mammoth" he said.

"Connor" she said in a low voice. He turned to look at her and she looked at him.

"I want to talk to you when this is all over" she said. He raised an eyebrow at her and nodded.

"Nightwing we have a visual on Parasite and Mammoth. We are engaging now" Superboy said through the mind link.

"Be careful" Nightwing said.

"Superbrat, so nice of you to join us" Parasite said smirking. They both stopped flying and landed on the ground.

"I see you brought your girlfriend, how sweet. Now what can you do?" Parasite asked looking at Wonder Girl. Superboy stepped in front of her and his eyes started glowing red. He used his heat vision and hit Parasite in the chest sending him into a building.

"Don't worry about her, you're fighting me" he said flying towards him. He grabbed Parasite by the throat as he emerged from the building. He flew him up into the air and threw him to the ground below. He looked to his left to check on Wonder Girl. She was holding off Mammoth pretty well, he turned back to see Parasite getting up.

"Wonder Girl, are you okay?" he asked.

"Yeah I'm fine, this guy is easy" she said. He smirked and flew towards the ground.

"Well it seems you've developed some new powers" Parasite said smirking. Superboy just kept his arms crossed over his chest.

"I'm going to enjoy taking your powers" Parasite said charging at him. Superboy took a deep breath and blew his cold breath on Parasite who began freezing. After a few seconds Parasite was a big chunk of ice. He turned his head and saw Mammoth toss Wonder Girl onto the floor. He sped over to them and punched him in the jaw as hard as he could and he flew into a building.

"Are you alright?" he asked helping her up. She nodded and wiped some blood off her mouth.

"Wonder girl, Zeta squad needs your help. Can you leave?" Artemis asked. Superboy nodded at her.

"I'm on my way now" she said.

"Connor" she said in a low voice. He raised an eyebrow at her and she leaned up and kissed his lips.

"Be careful" she said.

"You too Cassie" he said kissing her cheek. She blushed and flew off to help the others.

"Well isn't that sweet" he heard a voice say from behind him. He turned around and his eyes widened before a car hit him.

Alpha Squad

"Batgirl, are you okay?" Robin asked running to her side. She nodded and he helped her up while Nightwing was fighting off Bane. They had been fighting for about ten minutes now and it was a back and forth battle.

"I'm fine Robin, NIGHTWING!" she yelled as Bane punched him into a car. He fell to the floor and his eyes were closed. Robin shot up and tossed two bombs at Bane. They exploded and he staggered back a few feet. Batgirl threw a batarang with a rope on it, it wrapped around Bane's legs and she pulled causing him to fall on his back. Robin jumped on top of him and knocked out the tubes giving him his venom. He began to shrink instantly and then he passed out.

"Nightwing wake up" Batgirl said shaking him. He groaned and his eyes slowly opened.

"Oh thank god, are you okay?" she asked. He nodded and stood up. He saw Bane on the floor and nodded at the other two.

"Bane is down, does anyone need help?" Nightwing asked.

"Gamma squad is fine, Black Manta and Deathstroke got away though. We're looking for survivors now" Aqualad said.

"Zeta squad could use at least one more person. More soldiers keep coming" Miss Martian said.

"Batgirl, go help Aqualad and Blue, Robin and I will head out to help the others" Nightwing said.

"Superboy do you need help?" Nightwing asked. They didn't get an answer so he tried again.

"Superboy can you hear me?" he asked.

"Miss M is he still linked up?" he asked as he got to Zeta squads location.

"He should be" she said.

"Sorry, I had to deal with someone" Superboy said.

Superboy

The car flew at him and smashed him into a building. He threw it off of him and cracked his knuckles. He looked over at Parasite and saw he was still frozen. He used his X-ray vision and saw Mammoth was still unconscious in the building. Then he turned his head to his new attacker. Honestly somewhere deep down he knew this would happen one day, he two of them fighting it out like they've always wanted too.

"You're gonna have to do better than that…La'gaan" Superboy said standing up.

"You don't seem that surprised" La'gaan said bulking himself up with magic.

"Well you've always been a little shady. I guess I know why now. I just want to know how long this has been going on" Superboy said hovering in the air. La'gaan shrugged and scratched his head.

"Two months I think I'm just glad they let me fight you" he said jumping at him. Superboy sidestepped and grabbed his arm. He spun him around and flung him into a wall.

"I can't say that I'm going to miss you around the cave" Superboy said picking him up and smashing his head into the floor. He tossed him like a rag doll into a van.

"Still weak as ever" Superboy said. La'gaan ran at him and threw a punch, Superboy caught it and head butt him. He heard a crack and smashed La'gaan into the floor causing a crater to form.

"Superboy do you need help?" Nightwing asked. Superboy ignored it and tossed La'gaan into the air and flew up after him.

"Superboy can you hear me?" Nightwing asked. Superboy punched La'gaan down to the floor causing another crater to form.

"Is getting the crap kicked out of you all you can do?" Superboy asked as he landed on the ground La'gaan was struggling to get up and he spit out blood.

"Miss M is he still linked up?" Nightwing asked. Superboy rolled his eyes as La'gaan jumped at him and punched him in the face. He staggered back a few feet and Superboy used his heat vision and burned La'gaan's chest. La'gaan screamed in pain as Superboy burnt the word traitor into his skin in Kryptonian. When he finished he punched him in the face and he passed out.

"He should be" Miss Martian said. Superboy flew over to Mammoth and brought him over to Parasite in a flash. He used his cold breath and froze him right next to him. He picked up La'gaan and started flying towards the others.

"Sorry, I had to deal with someone" Superboy said. He arrived in a few seconds and he saw everyone gathered around a pile of rubble just sitting around.

"What happened to La'gaan?" Miss Martian asked in an alarmed voice. Superboy rolled his eyes and slammed him into the floor.

"Fish boy here betrayed us. He attacked me, so I did this" Superboy said turning him over and revealing the burns. Everyone gasped and Nightwing looked up at him.

"What is it?" he asked.

"It says 'Traitor' in Kryptonian. I figured it suits the little bastard" Superboy said crossing his arms over his chest.

"Don't look at me like that, he deserved it" Superboy said to Miss Martian.

"I don't think it's right to do this to anyone. You're abusing your po…" she trailed off and turned her head away from him.

"Abusing my powers really M'gann. You're going to talk to me about abusing powers after what you did" Superboy said lifting into the air. They waited for the League to come and take away all the villains. The team took La'gaan with them and when they got to the cave they locked him up and put an inhibitor collar on him. Connor was waiting outside the interrogation room while Nightwing was in there with the traitor trying to get information out of him.

"Hey Connor" M'gann said walking over to him. Artemis was next to her carrying her baby. He just grunted acknowledging they were there and Nightwing stormed out of the room and slammed the door behind him.

"Plan B" he said and he walked off to the computers. Connor smirked and walked into the room. The door shut behind him and he heard La'gaan gulp.

"So you're being stubborn, what a surprise there" Connor said sarcastically.

"So why did you betray us?" he asked standing behind La'gaan.

"Wouldn't you like to know" he snarled. Connor sighed and grabbed the back of his head and smashed his face against the table. He cried in pain and he was bleeding from his nose.

"Why did you do it?" Connor asked again.

"I'm still not talking" La'gaan said. Connor sighed and smashed his hand against the table and broke it. He cried in pain and Connor lifted him into the air by his throat.

"Why did you do it?!" he yelled pinning him up against the wall. Connor punched him in the face and he broke through the wall and landed near couch. Connor stepped through the hole and walked over to La'gaan and lifted him into the air by his throat.

"Connor put him down!" M'gann shouted. Dick put a hand on her shoulder and looked at Connor.

"Has he said anything?" he asked. Connor shook his head and Dick sighed.

"Continue" Dick said. Connor slammed him onto the floor and kicked him repeatedly in the ribs and face.

"Okay…Okay…I'll talk" La'gaan said. Connor smiled and pinned him up against the wall and waited for him to talk.

"He promised me power, enough power to kick your ass" La'gaan snarled.

"That's why you did it, so you can beat me" Connor said chuckling.

"Who promised you power?" Dick asked walking over to them.

"Darkseid" La'gaan said. Everyone's eyes widened and Connor was about to punch him when Dick stopped him.

"Let the League deal with this traitor" he said. Connor smirked and punched him anyway knocking him out. Dick rolled his eyes and Connor just shrugged. They put him back in the cell and walked out to see the two people they brought in were still passed out.

"When they wake up come and get me" Connor said walking to his room.

One Hour Later

The League had come and picked up La'gaan. He's being held prisoner in Atlantis right now. Aquaman was beyond pissed and almost killed La'gaan before they left. Connor was lying on his bed in his room wearing his usual black Superman shirt, jeans, and white socks. He heard a knock on the door and he sighed, he looked at his clock and sighed again, it was almost 10. He stood up and walked over to the door and opened it.

"Hey" Cassie said smiling at him. He let her in and she hopped on his bed and laid down. She was wearing a black t-shirt, blue shorts, and no socks or shoes. He rolled his eyes as she started tossing the football he had up in the air and catching it.

"So what's up?" he asked sitting down at the foot of the bed. She stopped throwing the ball and tossed it on the floor. She sat up and scooted next to him.

"Just wanted to talk, I missed you" she said blushing slightly. He smirked slightly and nodded his head.

"I missed you too" he said.

"Really?" she asked. He nodded and she kissed his cheek. He looked at her and raised an eyebrow.

"What was that for? Also why did you kiss me earlier?" he asked.

"Well…you know…I was just…you know…" she trailed off and looked away from him. She took a deep breath and looked towards him

"I wanted to know if you would go out with me" she said extremely fast. His eyes widened and she turned away from him.

"Cassie" he said in a low voice. She turned her head to face him and he crashed his lips to hers. She was taken back slightly but eased into the kiss. She wrapped her arms around his neck and he put his arms around her waist. They fell back on the bed so she was straddling him. They never broke from the kiss until they heard a knock on the door. They pulled away and stared at each other. Both of them were breathing heavily and blushing.

"Is that a yes?" Cassie asked.

"Yeah" Connor said smiling. There was another knock and they both got up and went to the door.

"They're awake, we talked to them for about five minutes and they asked for you" Dick said gesturing to Connor. He raised an eyebrow at him and they followed him out to the main room. When Connor walked into the room the two new people standing there, the girl flashed a big smile and ran over to him while the boy just stood there. She wrapped him in a hug and he looked confused.

"Connor it's so good to finally meet you, brother!" the girl yelled. Everyone's eyes widened and Connor just stood there in shock.
