Chapter 1:

At Mount Justice

The sun was shining. The clouds were gone from the sky. Early June had brought the promises of an amazing summer and the Young Justice squad wasted no time realizing that their headquarters came with a private beach! M'gann had wasted no time shapeshifting herself and her outfit into a yellow polk-dot bikini she was so excited about after hearing the song, and grabbing a basket of snacks she had made for everyone. Wally and Robin change into their own bathing suites, Wally in a pair of red trucks with the lightening bolt symbol printed on, and Robin with a pair of black and red trucks. Superboy unfortunately did not own a bathing suit, so decided to stick with a pair of shorts he had in his room. Aqualad decided on a pair of briefs that had a red and blue pattern. He has a ton of swimwear to choose from but this was by far the most casual. Artemis had decided on a black one piece with slashed cut into the sides to wear for the occasion and had wasted no time calling Zatanna to join them as well. She had to beg her father to let her join, but he finally broke down. She came over donning a purple bikini with a frilly top to it.

"This is the life!" Kid Flash hollered as he ran towards the water at normal speed and taking a dive into the water. "Come on everyone! What are you waiting for?"

"Well sorry we don't all live at 100 miles per hour..." Artemis responded. She grabbed a towel and laid it out on the sand. "I'm just gonna lay out for a bit. No need to get my hair all wet yet.."

"So this is what it's like to be at the beach!" M'gann was extremely excited for her first actual trip to a beach. Though the sun's rays and the heat were a little uncomfortable to her, she was enjoying a day off with her new family. Especially since Connor was also sharing this first time experience with her as well. "Conner! Let's get in the water!" she screamed she she grabbed his hand, shocking him by her touch. He couldn't believe that this wonderful, excited creature took him as her boyfriend.

"Finally jumped in babe?" KidFlash chuckled.

"The water is amazing! I've never been to the beach before."

"First time for everything!" Wally exclaimed and splashed water at M'Gann and Superboy. The water hit Superboy directly in the face, some going into his mouth and making him choke.

"Hey!" Superboy yelled angrily. "What the hell is your problem?"

"Whoa! Dude! That's what you do in the water. Y'know..? Splash each other. It's a game to see who gives up first." Wally explained.

"Oh.. Like this?" Super smirked as he put all his superstrength into creating a wave. Kid flash screamed as he started to swim with his superpower speed to outswim it, but it caught him and started dragging him into the beach causing him to land on Artemis..

"Wally!" Artemis yelled pushing him off of her. "I was trying not to get wet!"

"Sorry! I cant help Superboy decided to make a Superwave!"

"UGH!" Artemis stood and kicked sand at Wally. "Get away from me!" She grabbed her towel and walked away.

Wally groaned and rolled over. Why couldnt he just get one decent move in on M'Gann without anyone getting in the way...

"Hey! What's that?" Robin yelled as he pointed in the distance. He looked a little closer. "It's Superman!"

"Great..." Superboy groaned. Everything was always so awkwards between the 2 of them.. As if Superman wanted nothing to do with him. But as he noticed Superman getting closer, he noticed that someone else was with him. Another flying superhero. And when they landed, he couldn't believe his eyes. He could not believe that there was a young girl with an S as her emblem as well, no older than he, with Superman.. What. The. Hell.

"Everyone! Enjoying the sun today?" Superman asked the Young Justice squad as they all started to gather around.

"Hey Superman. Who have you brought with you?" Kaldur asked as he approached the Man of Steel. The young girl standing next to him was petite, but still toned with a similar frame as the other girls. Her blonde hair was shoulder length with a black ribbon in it. Her costume was similar to Supermans, but she had a white t-shirt and a blue mini-skirt with her short red cape. Her outfit finished off with a pair of red boots. Her arms were crossed and she did not look very happy to be there.

"This is my cousin, Supergirl. She found her way here from Argo City, a small piece of Krypton that survived the explosion. I thought some time with the team would be good for her since she is more in your age range." Superman answered.

"In otherwords, Superman is busy and doesn't have time to spend with his dear cousin while, so I get dumped here..." Supergirl huffed.

"Damn, we're not that bad... Are we?" Wally exclaimed, a little insulted by Supergirl's comment.

"I just have some League business this week Kara.. You'll be fine until I'm done." Superman put his hand on her shoulder. "Get to know the team and hang out here. I'll be back when I'm done." He said before flying off.

"You owe me!" Superegirl yelled as Superman flew away. She turned her attention back to the Young Justice squad. "So... Beach day?"

"Just having a fun day off. You're more than welcome to join." Robin replied.

"Sure! Give me on second to change." And just like that she disappeared and reappeared in a flash, almost as fast as KidFlash. "Ready!" She exclaimed, not changed into a red strong bikini. "So who is everyone again?"

"I'm Robin." Robin stepped forward... "This is AquaLad, KidFlash, Artemis, MartianGirl, Zatanna, and Superboy. Pleasure to meet you Sup-"

"SuperBOY?" Supergirl responded. "And what part of Krypton are you from? I thought Argo City was all that was left."

"I'm not." Superboy answered curtly.

"Then how-"

"No more questions. I don't have time for this." Connor stomped off, furious that Superman had time for this girl but none for him.

"Connor! Wait!" M'Gann yelled as she chased after him.

"What's his problem..?" Supergirl asked.

"There's a possibility that Superboy may be a little jealous that you actually have a relationship with Superman, while he does not.." Kaldur explained.

"I had no idea.." Supergirl responded. "I always figure if I ever happen to meet someone with Kryptonia traits they are also from Krypton."

"As you should. However, Superboy was cloned in a lab with DNA from Superman. Not born on Krypton like you and Superman."

"That makes sense. Maybe I should go talk to him?"

"I would let him cool down first. He'll get over it and warm up to you in no time." Wally chuckled. "I'm Wally by the way."

"You can call me Kara." Supergirl smiled. "So what are we waiting for? Beach day!" Supergirl exclaimed.

AN- Okay! A nice long chapter to hold you over til I can update again. Hope you enjoyed!
