Supergirl will be in her Superman: The Animated Series form.
Supergirl. Pfft. What a joke. Everyone knows she's not as strong as Superman. With a little Kryptonite you can easily beat her. Maybe you'll make her your sex slave before you kill her. Oh, about you? Well for starters you're a genius, you mostly specialize in robotics. Lexcorp has nothing on you. Why kill Supergirl you ask? Because you're evil and you can. Now, to formulate a plan... Disguise yourself as a civilian needing help and then spring the trap. Ha ha, brilliant.
12:00 PM, Metropolis Grand Station
You sort of regret doing this now. You tied yourself to the train tracks. You can see the train coming ever closer. Uh, someone help me! Right as the train is about to crush you, you are whisked off of the tracks faster than a bullet, and in the arms of Supergirl. How'd you manage to get tied to train tracks? A villain obssessed with old Westerns did it to me. Hmm... Cant say I know him. So where do you live, I'll drop you off. You tell Supergirl where you live and a few minutes later you arrive at your house.
12:05 PM, Your Evil Lair, Metropolis Outskirts
I guess I'll be off then. Wait! What is it? I have to thank you, I have something for you. It's not necessary. Oh no, I insist. You pull a small box out of a drawer and open it in front of her, revealing a large chunk of Kryptonite. Supergirl looks like she's getting weaker and falls to the ground. You go over to check on her and then gets back up at lightning speed and pins you to a wall. What! How? Nice try. But I'm not from Krypton. All the powers, but none of the weaknesses, perks of being from Argo. Damn, you knew she had super strength, but she's crushing all the nano-robotics under your clothes. You were gonna hurt me, that means I'm gonna have to hurt you. Wait, heroes dont do that kind of thing! Let's just say I haven't had the "sensitivity" training Superman has had. Her eyes glow red as she readies her heat vision. Holy! Jeez lady! Is what I did really that bad?! Her eyes stop glowing and turn back to their normal pretty blue color. You have pretty eyes. Dont try and flatter me weasel! I'm sorry. Stop doing that! Doing what Supergirl? That! You're trying to get me to let you go by talking your way out of it. I'll have you know that I have a will of steel! Ok then. Would you let me go to allow me to do one thing? Depends on what it is. Well, I only want to worship you like the goddess that you are. I'm intrigued now. She lets go of your arms but keeps her eyes on you like a hawk. You get down on your knees and start kissing the tops of her red boots. (This is easy considering some of the supervillains you've worked for, you certainly do not have a foot fetish or anything) I like you. Ever considered being my servant? Depends on what I have to do, you say giving her a smirk. Well, you know. You'd come back to my apartment with me and basically do whatever I say. Then I'd... reward you... only cause you're kinda cute. She winks at you. Alright, I'll do it. Wait, how many beds have you broken? Hmm... I'd say... one... hundred... in the past two years. Yikes... Be gentle? Just for you. But wait, wouldn't you get all sorts of... Super immune system, I cant get diseases or anything like that. Oh, and um... Sometimes I lose control of my powers when I get turned on... you know, I've had them leave with burns, frostbite, broken bones... Dont worry, I live close to a hospital for a reason. How old are you? Twenty. Why? Just curious is all- whaa! She pulls you up and gives you a hug... which kinda hurts. She releases her vice grip on you. Ok, to become my servant, all you have to do is kiss my hand. I can do that. She extends her hand, shiny red nails glistening in the sunlight. You proceed to kiss her hand. Good boy. Just for fun why dont you kiss the ends of my fingers? Why? Because I'll give you a special reward. Oh fine. You oblige and kiss the ends of her fingers. For some reason that shade of red is so familiar to you. You've... worked with it before. It then dawns on you. Hey Supergirl? You can call me Kara sweetie. Ok. Kara? Yes? Where'd you get the nail polish? I made it. From what? Oh, you know... stuff... She says as she twirls her hair around her finger. Like? You know um... Red Kryptonite... What! You mean I just... It's in my system now... The effects are random I dont know what'll happen to me now... I might turn into a fish or something! No you wont. I know exactly what'll happen to you. My last servant couldn't take it... What? I'm scared now... I'll show you. She grabs your arm and whisks you off with her. A few minutes later, you arrive at her apartment.
12:15 PM, Supergirl's Apartment, Downtown Metropolis
She lets go of you and whooshes around her room. About 15 seconds later she steps out wearing civilian clothes. I still know that you're Supergirl. How does changing your clothes and hair, and then putting on glasses keep your identity safe? Most people aren't as observant as you, as far as 99.99% of the world's population is concerned, I'm just a girl from Smallville who moved to Metropolis. So uh. What was this thing you wanted to show me. Right! Follow me. She grabs your arm and whisks you into her room. Now... She pushes you onto her bed and crawls toward you like some kind of animal. Then, she does something strange. She plops her butt down onto your chest and then puts her bare feet on either side of your head. All of the sudden you smell something, you cant quite put your finger on it, but whatever it is, it's really turning you on. Kara, what kind of perfume do you have on? It's making me really turned on right now. I'm not wearing perfume, this smell is all natural. I thought that was Poison Ivy's schtick? Want me to tell you what's going on now? Please. Ok, you asked for it. She moves her legs and rests both of her soft bare feet on your face, which you oddly have no objections to... You even get the urge to start licking her delightful soles. After about 5 minutes, she pulls her feet away. Ok, that was your treat. But now your training begins. Training? You know, like learning to give me good foot massages and pedicures. What do you say sidekick? Pardon? Cmon, I know that you can build some kind of super exosuit for yourself and help me out. Didn't you get the memo? I'm a supervillain Kara. Tisk tisk. Too bad. I guess I'll just have to deny you access to my feet. You cant do that to me! I can and I will. You're lucky that I dont put you in a pink outfit that has footboy plastered all over the front. Fine. You mumble bitch under your breath. Her eyes glow red and she glares at you. I have super hearing... Remember that. Her eyes turn back to normal. Fine, I'll help you. Goodie! I'm gonna let you know now. If I catch you doing ANYTHING evil. Automatic no feet for a week. Am I clear? Yes Kara, you say obediently. Good, you've learned your place... She pats you on the head.
