CHAPTER 1: Enter: Karlena Astra Luthor Danvers

National City 2039

National City. The home of its greatest hero: Supergirl, the cousin of Metropolis' greatest hero: Superman. Everything seems to flow normally (or as normal it can get) there. Few crimes here and there, but nothing the city can't handle and it's been quite peaceful. However, there's one person in the city that threatens to disturb the peace.

On top of the L-Corp building, there stands a girl in her teens with a hoverboard tuck underneath her left arm. She has long wavy blond hair and piercing green eyes. She's wearing a shirt that has one sleeve rolled up while the other is rolled down, saying the words "Be A Hero" in Yellow, Blue, and Red writing accompany with some jeans while a flannel tied around her waist. Her shoes are red and blue. One is red and the other being blue. Around her neck, she's wearing an "L" necklace and lastly, on her right arm, she wears a Supergirl watch that was given to her as a child and she kept ever since. The teen girl lets out a breath as she says "Okay". She then puts down the hoverboard on to the ground and looks outward of the city.

"Alright National City, Karlena Astra Luthor Danvers is gonna do the biggest stunt in her young life!"

Just as she was about to push off on the hoverboard, a hologram suddenly pops up in front in her, yelling "KARLENA!" Karlena stumbles a bit by that sudden interaction, making her slip out of the straps. She then looks up and sees a teen girl with medium length red hair, staring back at her with brown eyes and clear anger on her face. Seeing who it is, Karlena smile shyly. "H-Hey Cuz"

Karlena's cousin wasn't having it. "Karlena.." She says sternly "Did you happen to take my mom's hoverboard by chance?" Even though she already knew the answer, she wanted to see if Karlena will come clean about it. Karlena looked at her in disbelief as she sputters out "Wha-um no! Me taking Aunt Alex's hoverboard? Pssh what?! Seriously Elizabeth?"

Elizabeth gives her a 'come on' look. "Karlena. You can stop lying"

Karlena went to open her mouth to say something, but settle with a groan. "Is it obvious?"

Elizabeth cracks a smirk on her face as she jokingly says. "Let's just say that those Luthor genes didn't kick in yet"

"Hardy har har" Karlena says back with a smile as she begins to strap herself on to the hoverboard again. Elizabeth sees this and quickly her tone changes.

"But seriously Karlena. This is too dangerous. You need to stop before you hurt yourself"

"No way Liz, I'm doing this"

"This is crazy you know"

"I know! But I'm gonna be fine. They'll see"

Elizabeth falls silently as she observes her younger cousin with a sadden look.

"Karlena..Whose attention are you really trying to get?" She asks.

That seems to strike a nerve.

"What? *krr!* I *krr!* can't *krrr!* hear *kkkkrrrrrr!* Gotta go! *KKKKRRRRR!*" Karlena says as she quickly starts up the hoverboard.

Really Kar-" Elizabeth was about to say but just as Karlena kickstarted the hoverboard, her watch beep. She looks down briefly before looking back with wide eyes! "Karlena wait!"

But it was already too late, Karlena took off on the hoverboard and jump off the building, screaming "WOOOHOOO!" She then leans forward like she's a skier going down a snowy slope as she rode down the side of the building! With some force, she then pushes herself off the wall and begins to go at full speed through the air. Zipping pass buildings and into between them. "Ha HA! This is awesome!"

She then does a loop before breaking into a nosedive down to the ground as she spins pass humans and aliens, while they all take cover or jump away from her. Causing many angry grunts and comments along the way, but Karlena is so caught up in the exhilarating moment to notice. After believing she has enough time on the ground, she decided to go straight upward with a big smile on her face. As she rides upward, the sound of the engine roaring starts to sound very faint. Feeling the nice breeze on her face and having complete control,

she closes her eyes as she takes it all in. As if she belongs in the sky. She then opens her eyes again as she said with a smirk "Seriously. I really don't know why Elizabeth was worrying. I'm totally fine!"

Suddenly, the engine cut out. She then looks down and saw how high up she was, which was very high. She then facepalms herself.

"Oh. That's why" She says matter of factly.

With that said, she instantly falls down!

Karlena screams as she plummets down at an alarming rate! 'Oh Rao! This isn't good!' Karlena thinks to herself frantically as the wind violently whips her hair into her face while grasping out to nothing. Not wanting to see her death, she closes her eyes tight.

'It can't end like this!'

Suddenly, she felt herself come to sudden jolt! Almost instinctively, Karlena opens her eyes and sees that she still in the air. In complete disbelief, she looks down and to her surprise, she finds herself..floating with the hoverboard still attach to her feet! That can't be right. The engine died so there's no way that's holding her up and obviously, Karlena can't fly!

"Karlena" Said a stern voice. She closes her eyes. 'Oh no. I have done it now'. Mustering up the courage, she then opens her eyes and slowly looks up as she comes face to face with none other than Supergirl, herself, as she holds her arm that has the Supergirl watch. She's clearly giving Karlena a concerned look while Karlena gives her one of her big "victory smiles"

"Haha…hey there, Supergirl. How's it hanging?"

Alright guys that's the first chapter! What do you guys think of it so far? The next part will be up hopefully tomorrow or Wednesday. CC OUT! :D
