My impulse -EDIT-

Rogue

I sit in the dark room chained to the wall whimpering. The door opens revealing a man in a white coat with a clipboard and another person who is also in a white coat with glasses. "This is project Rogue, it's a project I have been working on to destroy the justice league." I stare at them carefully making sure they don't get too close. "Why is this child chained up? Where's her parents?" The man laughs "Dr. Stewart I assure you it's not human, it's not even alive, it's nothing but a weapon that was created from a bottle to look human. It was never born or conceived like a human or animal so why should it be treated as such?" The man looks at me carefully "does she have a beating heart?" The other man looks at him taken back by what he said. "Well of course it does that's the whole point to make her..." dr. Stewart cuts him off "and she has a gender, she's human enough to me. It doesn't matter how she was brought here she's still a living being. As long as she looks, breath, eat and live like us she's still a human child." I can feel his emotions it's pure unlike the other man who had his people torture me saying that it's supposed to help me get stronger. "Don't get too attached" dr. Stewart studies me a bit after the man left. He walks closer to me crouching down to my level, I back away from him still not sure. "It's ok" he pulls something out his pocket "here take it" it's round, I quickly take it and I sniff it. It smells sweet and it feels soft "it's a cookie" I take a bite and I smile eating the whole thing. I put my hand out for another one and he smiles taking my hand. "I promise I will have more and I promise that I will get you out of here. I know the perfect person to take you in." He pats my head and leaves, leaving me in the dark alone.
"Wake up it's time for your training" my tail tuck between my legs knowing what's coming. They put me in a room with a machine that has the abilities of every superhero. This training happens all day everyday including combat training. Guards would come in to shoot at me some times and sometimes they electrocute me. "Tomorrow you will be fighting against superman robot in front of a few scientists including Lex Luthor we have to show him that you are ready." My ears go back, I look at Dr. Stewart and he just looks away. I scream in pain feeling bolts of electricity course through my body. "You need to be stronger, guards!" The guards come in with guns to shoot. "What are you doing?! Stop this!" I form a force field for myself crying "she needs to stop feeling those feelings and give me more of the killer she really is!" They continue to abuse me until I actually snap. I turn into a wolf growling my eyes red, the men stop and try to run, but I didn't give them a chance. I ripped their limbs off including their head. All the anger coursing through my body I couldn't hold back anymore.
"ROGUE!" My eyes slowly turn back to normal and I start crying as I shift back. The man smiled "good that's what I need for tomorrow" he frowns "stop crying you don't have feelings." He pulls me by the leash dragging me to a different room. "Dr. Stewart will be checking for any changes" then he leaves.
"Here I brought another cookie this time a bigger one" I smile eating the cookie. I feel a hand on my back and I instantly snap at the hand "hey it's ok I'm just checking for any problems anything new." He continues to look and write down a few notes. It looks like today was nothing but torture surprisingly. I guess it's because of tomorrow "tomorrow after the event when everyone has finally left for the day I'm taking you somewhere safe, but you will have to be sleep for it. It's for your own safety." I hold out my hand wanting another one and he smiles "tomorrow I will have more cookies for you."
I sit in a room staring at the people watching me."Thank you for coming, today I like to show you a new experiment called project Rogue. She can easily take down the league starting with superman" the robot comes in with red eyes, my eyes turn red as well ready to use heat vision. Our heat vision clash together, my eyes starting to hurt so I quickly close them which was a terrible move. The laser burns me on my chest luckily it healed but it still hurts. The bot starts moving fast hitting me in all kinds of directions. I start to panic then I see the man getting angry with me, I quickly think before the next punch comes in then it hit me! Kryptonite! My tail and the top of my ears turn green giving off the same minerals the rock has. "Impressive, but this is a robot it's not actually superman, which means it's temporary." the bot drags me across the floor pulling on my tail, I teleport and use ice breath freezing the robot shattering the bot to pieces. "Hm, I want her in my office tomorrow morning on a leash of course. I don't want her running around trying to kill me" I growl. "Of course!"
I'm back in the darkness again alone, the door opens revealing Dr. Lawrence "cookie!" He looks at me surprised "you can talk?!" I nod as he smiles patting my head. "Here's another cookie" I eat on the cookie enjoying the flavor, but it's off, the taste is off. I look at him my vision becoming fuzzy "I'm sorry, I told you that you will have to be sleep for this to happen." Then everything is black.
