AN: So this is my first M rated fic. Rated for adult themes. This is going to be a long fic, but I think you will all enjoy it, so without further ado, here's the story!

Prologue

Buttercup's POV

It was our first day of summer break after graduating high school, and we were all surprisingly bored… and hungry.

"Where's the professor at? He said he'd be home at 5:30 with dinner and it's 8 now! What could he possibly be doing for three hours?!" I had been waiting for the Professor to come home to eat anything and frankly, I was starving… and pissed.

"Calm down Buttercup, he probably got caught up in some new breakthrough, you know how passionate he is about his job." Blossom rolled her eyes at my impatience. The professor had recently been offered a job in the military as a chemist to design new weapons for the military, and he loved his job.

I was about to start up on another complaint when the phone started ringing obnoxiously loud. I quickly picked up the phone and screamed irritably into the speaker. "WHAT?!" I was expecting the person to hang up immediately, but I felt all the blood drain from my face as I heard an eerily familiar voice come through the line.

"Why hellooo there dear Buttercup. You don't sound very happy, why is that?" It was HIM, the echoing falsetto was unmistakeable and I wasn't in the mood for dealing with his crap.

"Cut the crap, what are you calling for?" I hissed in a whisper, not wanting to alarm my sisters if there was no reason to.

"Always so impatient my dear! I have decided upon a proposition for you." I almost choked at his implications, there was no way in hell I would ever make a deal with the devil.

"No way! I know not to make deals with you, that'd just be stupid on my part!" I made sure my words were forceful, but not too loud. I could almost feel the smirk drop off his face at my response.

"Well. You might want to reconsider," his oh so pleasant voice changed into one more true to his nature, "if you ever want to see your precious Professor alive again!" My blood turned to ice and I swear I died for a split second.

"Ok. I'm listening…" I pictured his shit eating grin crawl slowly back onto his face and tried not to scream.

"Good, gooood. Now listen well dear, this is important for you to understand. In order for me to spare the Professor, you or one of your sisters must take on my challenge. It consists of fifty challenges you must completed within the day unless the time frame is changed in the challenge. If you fail to complete any challenge within the time limit, you must choose whether the professor will die of you will take his place. If you don't accept this challenge…" his voice once again dropped to a demonic growl, "the professor is as good as dead!" If possible, more color drained from my face and I had to swallow the giant lump in my throat before responding.

"I'll do it."

"I figured you would my dear. Be at my lair no later than 9 AM, we will go over some ground rules. Come alone and your sisters can't know about this. Tell them he's on a mandatory surprise business trip." Without even waiting for my answer, HIM hung up the phone.

"What did the person on the phone say, Buttercup?" Of course Bubbles would be the one to be curious.

"It was dad, he said he was going on a mandatory surprise business trip and won't be back for a long while. Guess we have the house to ourselves for the summer…" She looked very upset and I felt guilty that I couldn't comfort her as I stormed into the kitchen to make myself dinner.

I poured a big bowl of my favorite cereal, too mentally drained to put up the effort and make a real dinner. I stuffed myself with the frosted flakes and mini marshmallows until I couldn't eat anymore. Without a word to my sisters, I decided to retire for the night, setting my alarm for 8, if there was something in life I wasn't going to be late for, it was this.

••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••

I woke up the next morning to a blaring beeping sound from my alarm clock that I rarely used. Memories from yesterday rushed back to me and I jumped out of bed and started getting ready. I ran to my closet and after short consideration, I picked out a lime green cut off t-shirt that showed just above my belly button, low rise ripped denim jeans that reached my upper thigh, and topped it off with a pair of neon green sk8-HI vans. I looked in the mirror and started to brush my bow waist length hair until it settled into neat waves and straightened my new sideswept bangs, pushing them out of my face slightly. I didn't use nearly as much makeup as Bubbles and Blossom did, I only used black eyeliner and mascara to make my eyes pop. I never wore foundation since I didn't want to cover my light freckles, something that set me apart from my sisters. I put in my normal three crystal earrings in each ear and flew out of my window towards HIM's lair.

It was 8:45 when I arrived in front of HIM's door. I always thought it was weird that he lived in a regular house considering he literally came from hell, but whatever works. I knocked on the door and he immediately opened it, ushering me inside where I see the Professor tied to a chair and I couldn't tell whether he looked scared, relieved, or worried, I was never good at reading people.

"Now to go over some ground rules for this challenge dear Buttercup… You may not use your powers whatsoever during ANY of the challenges. To make sure you won't, I will take your powers for the time being and leave them in the care of the Professor." My eyes went wide at the revelation that I couldn't use my powers that I had relied on all my life. "That's not all, nobody, not even your sisters can know about the challenge or why you are doing the things you are. If anyone asks, your answer must be 'because I can and I want to.'. Also, the professor will know all of your challenges ahead of time and he will be able to sit here and watch your progress through media, videos, and news reports. Now… are you still up to the challenge?" I definitely felt apprehensive about the situation now, but this was for the Professor.

"Buttercup, don't do it! I've lived long enough, just go on and live your own life, you're 18 now, you don't need me anymore!" I knew he hoped that by saying that he would keep me from accepting the challenge, but him saying that just reminded me why I would do anything to keep the Professor safe.

"I accept your challenge." I looked over at the Professor, "Sorry dad, but I can't let you go." I walked over and hugged him and placed a soft kiss on his cheek. I whispered in his ear, "It'll be ok dad, I love you." He repeated my words back to me with tears in his eyes.

It wasn't long before HIM interrupted our father daughter moment. "You should get going dear, your first challenge will be on your dresser first thing in the morning with whatever you will need to complete the challenge." His voice once again flipped into a malicious snarl. "Have fun Buttercup!" With that, he pushed me out the door and I walked back home, having had my powers drained by HIM, what did I just get myself into?

AN: so here's the prologue, stay tuned for Buttercup's first challenge and hopefully the other 49 if she makes it until then, dun dun dunnnn. Please review and tell me if you like it so far!
