🌹you are 12.
🌹your sorta like Slender man. You have tentacles, they are (f/c). You don't kill people. You have wight skin and (h/c) hair. You have (e/c) eyes and a mouth.
🌹the league meets you in the forest.
"Why are we here in a dark, creepy, cold forest again?" Asked Flash looking around.
"We got some reports that there's a creature around here that only comes out at night," Batman told them "it hasn't attached anything yet, it lowers people in with its singing, apparently is known to look like a child".
"Are you kidding me, if this is some prank I'm gonna-" Green Lantern(Hal) was cut of by some singing. They started to follow it.

[There should be a GIF or video here. Update the app now to see it.]

They finally made it to a lake to see a child, but it looked different from other children. Extremely different. You had skin as wight as snow. You figure was small but well built. But what really got there attention was the tentacles coming out your back and drooping on the hard cold ground. You looked saddened and depressed.
"It that the creature?" Asked Green Arrow.
"That cant be it, it is only a child" Whispered Wonder Woman.
Someone (Flash) decided it was a good idea to run up behind you.
"Hi there" he said.
"AHH!" One of the tentacles knocked him back into a tree.
"Flash!" Yelled Superman as he flew to help him.
You saw and stated to run away.
"Kid wait!" Yelled Green Arrow.
You used one of the tentacles to grab and swing from tree to tree. They lost sight of you.
🌹you help people in need.
You kept swinging till you you saw a cliff. You started to  swing faster till you launched yourself across. You made it to the other side and saw a man staring at you. Of course you just thought he was trying to hurt you. You started walking away, but then there was a gasp. You saw the man falling down the cliff.  You jumped down and grabbed him before he could hit the ground.
"Wow, thanks " he said. You just tilted. He didn't look normal. He was wearing weird clothes and a mask.
And he was dressed all in black. You tilted your head.
"Are you ok?" He asked you.
You started to climb out, your tentacles grabbed onto rocks that were sticking out the cliffs side. When you made it out you put the man down and started walking away.
🌹 you didn't have the best childhood.
"Wait, I just want to talk" the man said.
"Who are you?" You asked this strange person.
"I'm Batman," he told you (hehe, I regret nothing) "if you don't mind I would like to know your name" he told you crouching down to your level.
"My names (y/n)" you said looking at the ground.
"That's a nice name, I was wondering why you were out here alone, where is your family?" He asked.
"People kept calling me a monster and demon, one day someone came into my home and hurt my dad, mom told me to run into the forest and wait for her," you said tearing up "then the bad person went after her, she said she'll come get me, why isn't she coming back for me?".
He was taken back by this, you weren't a monster, but only a scared child waiting for your parents that will never return.
🌹you are very curious about things.
"If you want you could come with me and some other people who are like you" Batman told you.
"Ok" you whispered.
Batman spoke into his ear peace saying he found you. He then grabbed your hand and started leading you somewhere. You retracted your tentacles back into your back. You then noticed he was wearing a mask.
"Why are you wearing a mask?" You asked.
"To protect my identity" he told you.
"Why?"
"So people I know don't get hurt"
"Why?"
"Because I want to protect them"
"Ok".
Then there was silence.
"Are your friends nice?" You asked.
"Yes" he said.
"Are they going to hurt me?"
"No"
"Are they going to leave me?," you stopped "are you going to leave me?".
"Never".
Your pace started to become slower and slower at each step. Sleep slowly consuming you. Batman then picked you up. You placed your head on his shoulder and fell into the land of dreams.
🌹The League was surprised about your past.
Batman walked up to the waiting league.
"So this is the kid?" Asked Flash.
"Yes, there name is (y/n)" replied Batman.
They all boarded the jet and flew away from the forest you called home.
"So got any information about why the (y/n) was in the forest?" Asked Superman.
"They were waiting" Batman told him.
"For who?" Asked Wonder Woman.
"There parents"
"So your telling me (y/n) parents left them in the forest to fend for themselves?" Aquaman said angrily.
"No, there parents were murdered," he told them "from what I heard there parents were attacked by someone who saw them as a threat, there mother told them to hide in the woods and wait for her there but she was eventually killed as well, leaving (y/n) waiting for who knows how long to wait for them to come back".
The League looked at you, they didn't know what to say or do. You had stayed faithful and waited for your parent to return but little do you know they never would.
"poor kid" said Flash.
"So were taking them in?" 
"Definitely" replied the League.
🌹You have a hamster.
When you arrived at the watch tower you grabbed Batmans hand and walked out the jet with him. The league noticed movement in a little pouch you carried.
"Um what's in the pouch?" Asked Flash.
"Toby"
"Who's Toby?" Asked Martian Man Hunter.
A gray teddy bear hamster then popped out of the pouch. It looked like it was wearing a miniature pare of yellow goggles.

(Imagine the goggles on it)
"This is Tic Tac Toby" you said as Toby  climbed to the top of your head to look around. He then squeaked when he noticed that this area was safe for you.
🌹All the female heroes adore you.
You were currently in the Watch Tower sitting in the cafeteria eating lunch. All the female superhero were crowding around you cooing about how cute you were and how they thought you were adorable.
"Hey shorty" Flash said.
"I'm not short, I'm just missing the other half of me" you yelled at him.
This caused the woman to aww.
🌹Time for the costume.

Female

Male
🌹You are a beast when you get angry.
You were currently in your room playing with Toby when you heard screaming in the hallway. You instantly grabbed Toby and placing him the pouch. You ran out your room and saw Green Lantern (John) laying on the ground holding his abdomen. You saw the rest of the Justice League fighting a man with yellow and red. atrocitus and Sinestro. Superman was the last one standing, he then saw you about to be shot at by Sinestro. Everything went in slow motion. He threw him self in the way blocking the shot but taking the damage. You just stared at this. You then spoke.
"You hurt them," you whispered "you hurt my friends".
"Well of course we did, if we want to take over we have to destroy them" said
Sinestro.
"I don't like that,"your tentacles burst out your back "you hurt my friends".
Your teeth then got sharper and your once (e/c) eyes had become a crimson red. Your once sweet soul replaced with a blood thirsty demon.
"YOuLl pAY" you said readying your synth. You launched yourself forward ready to attack. atrocitus tried to hit you but you flipped over him and hit him with your synth. You then moved one of your tentacles to grab him. You grabbed him by the throat. You then went after Sinestro. He tried to summon a creature that should have scared you but you just chuckled.
"You think that scares ME!" You yelled sending a tentacle to grab his throat as well. Once you got them both the league has woken up. You were struggling to hold them so you cried out "A LITTLE BIT OF HELP OVER HERE!".
Once they got them retained and being sent to Green Lantern corp your eyes turned back to there normal, your tentacles retracted back into your back.
"Hey (y/n) are you ok?" Asked Hawkwoman.
You then proceed to fall on the floor and pass out from exhaustion. Let's just say you needed a well deserved nap.
🌹Your first appearance in public was one to remember.
You and the league just took down Killer Croc, Bane, Captain Cold, and Joker. The Justice League was talking talking to commissioner Gordon and taking care of the situation while you just stood there and waited for them to finish. News crews were taking pictures and doing reports when suddenly Bane broke out of his restraints and chucked a car at the crowd. It was about to hit a young boy and his mother when you jumped in front of them, entangling the car in your tentacles.
"You ok there?" You asked them.
"Yes, thank you" said the woman running away.
"You know," you said appearing in front of him "that wasn't a smart move". You then punched him in the face nocking him out.
You then fixed your glasses in that cool anime style.

The crowd went wild.
A news reporter came up to you and asked you "who are you?".
It took awhile but you figured out the perfect name.
"I'm moissonneuse (Reaper in French)".

🌹you leave the league to find some explanations.
You need to know.
Why do you look like this?.
Why do you have these abilities?.
Why are you, you?.
You were packing your bag readying to leave. You know the league wouldn't be happy but this was for the best.
You decided to write a letter saying why you left.
Dear Justice League
I have decided to look for answers of why I'm like this. I know there must be some explanation for why I was born into this world with these gift. For the time being I will be away looking for whoever or whatever cause this to me.
I will come back in the future once I find out.
Thank you for everything, I will never forget you all and I hope you never forget me.
Yours truly, (y/n).
PS- Don't let Flash, Green Lantern, and Green Arrow touch my things.

  🌹The Justice League were surrounded by some of Poison Ivy's plant when suddenly there was a tall figure destroyed her the plants. The person was wearing a cloak that covered there face. Before they new it Poison Ivy was stopped and the figure help them out of the trapped.
The person then removed there cloak to reveal a certain somebody.
"Hey guys, guess who's back?" You said with a smile on your face rubbing the back of your neck.
The league was in shock, well except Flash.
"Yourbackyoubackyourback" you yelled rushing up to you and giving you a hug.
"Yes, I'm back," you told him as your face started to turn blue "Need.Air. Now".
He then let you go. Then a certain team of sidekicks appeared.
"Who are you?" Asked Robin.
"Even better question, how did you do those tricks?" Asked a excited Kid Flash.
"Wow, never expected you guys to get partners," you said looking at the team, but then looked back at the league "well thinking about it was bound to happen sooner or later".
"Well who are you?" Robin asked again.
Green Lantern was about to say something but you cut him off.
"Well some people call me (y/n)," you then pulled out your synth "but you may know me as moissonneuse".
"Your moissonneuse, uncle J'0nn talked about you once, saying that you left but promise to come back" Megan told you.
"Well of course, I promise I would come back eventually".

Hope you enjoyed.
