Power Master Story Writer: Phew! I didn't want to make it a depressing chapter, just sad. It might be the finale... It might not... Who knows?

Exotoast135: Coming right up! Right after this one!

There it is... Now or never... Time to prove your strength...

Marco took a deep and easy breath, raising his hands to his chest and lowering them as he released the oxygen from his lungs. In front of him sat a slab of concrete, about 3 inches thick, propped up on two cinder blocks on each side of it, exposing the centre.

Marco stretched out an arm and brought his hand to the exposed part of the slab, lining it up so he wouldn't fumble and strike the cinder by accident... Again... Sweat began to form just over his brow, gliding down his forehead to be absorbed by his gi. He rotated his hand so that is palm was pointed towards the left wall, he turned his head and looked at the poster on his wall, the shirtless man giving him confidence as he focused once more on the concrete.

With the afternoon sun shining bright through his curtains to help his vision, he raised his hand into the air, sucking in a sharp breath and quickly swinging it downward, with the words "HIYAH!" escaping his lips. His hand went through the concrete like butter, his expression not ever changing as he struck the slab. Chunks of rubble fell to the floor, nearly falling on top of Marcos feet as he reared his fist back and brought it to his side, from there he looked at the rubble with an emotionless face as he closed his eyes and bowed respectfully at his, once whole opponent.

A sound of applause emanated from behind Marco, slow but genuine and he slowly turned in curiosity to see who had witnessed his accomplishment. Her hair was a golden blonde, reaching just below the back of her knees and shimmering slightly in the light with a red, devil horn headband just behind her bangs. Her eyes were an electric blue that sent shivers down his spine whenever he gazed into them, She wore a sea foam dress with a bright pink squid design in the centre and hand a bright yellow, star shaped handbag slung over her shoulder. She smiled brightly, her heart imprinted cheeks glowing with joy and excitement, causing Marco to smile right back at her.

"Nice work Marco! I didn't know you were so strong!" Her voice was like a feather, light and elegant but always beaming with enthusiasm. Marco's face began to heat up at her compliment, but didn't let it bother him in the slightest.

Marco slipped his thumb just underneath his brown-belt and gave Star an appreciative look, "Thanks Star, I've been training for a while but I never thought I would get this good!" he exclaimed, using his free hand to gesture to the small pile of rock that was once a solid block of concrete. Star's smile widened as she walked over and slipped an arm behind his shoulder.

"Well that's what happens," she started, using her other arm to poke Marco in his stomach rather hard, causing him to arch over slightly, "When you train for six days straight!" Marco smiled and gave her a soft nudge with his shoulder.

"Come on, enough fooling around. I still have to train for my black-belt ceremony, I'm going up against Jeremy and I don't want to lose this time." Star just snickered and roughly patted Marco on the back, she rolled her eyes and sighed happily, feeling content with her pestering, she walked towards the door.

"Just make sure you don't hurt yourself! I don't want my bestie to get any boo-boos!" She smugly yelled, causing Marcos cheeks to flush heavily with embarrassment. Once Star was gone he shut the door and walked over to his bed with a tired sigh, he was exhausted from all the training and he still wasn't sure if he could face Jeremy in a duel, Mono-on-Mono. Marco lay back on his bed, letting the warmth of the blankets sooth him as they seemed to envelope him in a warm hug... And slowly, Marco drifted into a light nap.

"You know... You could always use me to beat Jeremy..." a dark voice spoke, having a small growl in his voice. Marco shot up from his bed, looking left and right for the source of the mysterious voice, but there appeared to be no-one else in the room with him. Marco swung his feet over the side of his bed and raised himself into a standing position and taking a defensive stance.

"Who's there?" he asked, swiftly spinning on his feet so he was not taken down by surprise. "Do not fear... I am not going to hurt you, but I must say... It stings that you don't remember me..." the voice seemed to come from all directions and echoed throughout Marcos eardrums, yet something in his mind seemed to... Connect with the voice, as if he did know who it once was. "Why are you here? What do you want from me?"

The voice chuckled softly, and Marco recognized the sinister tone in it, it was impossible to forget. "I'm here to help you Marco... We may not have started off on the best of terms, but I just wanted to help..." Marco let out a scoff and dropped his stance.

"I'm sure you did, right after you over-ruled humanity and ate their bowels... You sicko..." The voice cleared it's throat nervously and Marco imagined it tugging on its collar. "I... I was just caught up in the moment Marco... Did you ever really think I wanted to hurt anyone?" Once again, Marco let out a scoff and rolled his eyes. "You beat Jeremy half to death and while it was appreciated, you tried to kill me afterwards!"

The voice groaned loudly, impatience seeming to overpower his tone, "I'm sorry Marco... I really am... But I do want to help you... I wish to undo all my wrongs and re-enter society as a noble and helping citizen... Sorta... I'll still be a 'Monster Arm' as you called me, but I will never commit any form of sinister deed..."

Now Marco was deep in thought, he rubbed his chin with the back of his index finger and tapped his foot softly against the hardwood floor. He could really use the extra oomph that Monster Arm gave him, and if he really did want to redeem himself, it would be wrong to keep him trapped inside Marcos head...

"I... I guess... It would be okay... But if you double cross me, I will NOT hesitate to turn you into sushi!" Marco warned, pointing to the roof of his room in an authoritive way. Monster Arm laughed darkly and whispered, "Don't worry... I would never think of it..."

Time Skip Quote: "SPACE UNICORN! SOARING THROUGH THE STARS!"

Marco slowly creaked open Stars bedroom door, peaking his head through the narrow gap he made and using his peripheral vision to spot anyone who might cause the failure of his mission. After spotting no-one, he assumed the coast was clear and began to slip through the crevice between the door and its frame, he had changed out of his Karate Gi and into something more fitting to the situation: He wore a black hoodie with a dark grey undershirt and camouflage trousers, with simple black Nikes for foot wear. On his head was a camouflage beanie and a small Bluetooth com-set in his ear, it wasn't connected to anything but it did look pretty badass.

"Was all this get up really necessary? We're only getting Star's wand, not breaking into the Pentagon..." Monster Arm complained, Marco shushed him and continued to sneakily make his way over to Stars drawers, where she left her wand when she was showering. Marco could hear Stars sweet singing from behind the bathroom door in her room, along with the sound of water striking the ceramic bottom of the shower floor. Her voice was so in tune and had a perfect key pitch as she recited the words,

"I think earth is a pretty great place!"

"That's saying something! Since I've been through outer-space!"

Marco couldn't help but blush at the sound of her singing, but he quickly shook it off, as if it were nothing. "I'm gonna quickly grab the wand, then I bring you back and we get the heck outta here! Understand?" Marco asked, peeking around the corner of Stars bed to confirm that the wand was still there. "Understood... Let's ROLL OUT!"

Marco dashed over from behind Stars bed frame, heading straight for the wand. He slid over to the drawers, straightening his posture, he reached his hand out towards the wand and wiggled his fingers in excitement, surprised at how easy the job turned out to be. But just as Marco was able to wrap his fingers around the handle of the wand, the water in the shower stopped.

Marco froze in place as he heard the showers glass door open and close again, soft humming making his cheeks flush a dark red tint. "Threat discovered! Abort mission! ABORT MISSION!" Monster Arm screamed, Marco winced slightly and sprinted to Stars bed with the wand in his hand. Panic set in as Marco dove underneath the bed, trying his hardest to slow his breathing but ultimately failing, he gripped the carpet below him, his nails scraping across it as they made a soft brushing noise. The bathroom door swung open and Marcos eyes widen as Star stepped into the room with wet hair and a towel firmly wrapped around her, covering all the necessary places, but Marco couldn't help but flush at the sight. His cheeks were hot and his left eye began to twitch as he continued to stare at the girl in front of him.

"Marco! We need to get out of here!" Monster Arm screamed, snapping Marco out of his thoughts and back into reality, "R-right... L-lets just wait for her to leave..." he whispered, still incredibly flustered by what he just witnessed, Star walked over to her dresser and grabbed a few clothes before skipping over to her bed and... dropping her towel...

Marco was screaming in horror on the inside as his cheeks flamed, he was in complete shock as Star proceeded to dress right in front of him. Sure, he could only see her legs but that was enough to make him want to give up and get out! Marco shut his eyes as tight as he could and turned his head so that he wouldn't be facing the horrible events of a girl getting changed... But it didn't stop him from thinking about what he might see...

"Ewww... Marco that's disgusting! This is your best friend, how dare you imagine her naked!" Marco opened his eyes in surprise, "Wait... You can read my thoughts?" he whispered, both impressed and angered that Monster Arm could do such a thing, Monster Arm scoffed, "Of course I can! I'm in you're head after all... And you think I'm the sicko..." he replied, Marco looked upward with his eyes in annoyance and ignored Star for a moment, proceeding to question the voice in his head.

"Well... Can you, like... See my memories too?"

"Yep... By the way, who wears a helmet in a gym shower?" Marco ignored his comments and continued his querying. "What else can you do?" Monster arm sighed Marco imagined him counting on his fingers. "I can read your thoughts and memories, enhance your strength at will, read you emotions, cover you in scales... Heck, I could even give you-"

"Wait, wait, wait..." Marco whispered, shaking his hands and head in a gesture for him to stop talking for a moment. "You can read my emotions?". Monster Arm huffed at his rudeness and decided that he would answer his question anyway. "Yes... I can read all natural substances from your body, even manipulate them if I wanted too, but I prefer to leave that power alone."

Marco looked down at his hands and pressed his fingertips together nervously, "Ummm... Well... Can you tell me something?" he asked, his cheeks burning red from what he was about to ask and hopefully get an answer to...

"Sure... What do you wanna know?" Monster Arm replied, a little sceptical but also very curious. Marco swallowed hard, taking a moment to calm himself and regain his composure, "How do I feel about Star?" he confidently asked, fully expecting a direct and to-the-point answer. The question had been sitting in the back of his mind for a long time, nibbling away at him whenever she gave him a hug or just struck a conversation with him. He used to be so sure that he wanted to be with Jackie but ever since the Blood Moon, when the duo danced beneath the red beam of the night, he wasn't so sure who he loved anymore...

Monster Arm sighed in defeat, hesitating for a moment before answering, "Alright... But what I'm about to tell you could change the way you see Star forever... In fact... You l-" Stars cough stopped Monster Arm from finishing his answer, Marco turned and looked at her through the small space between the floor and her bed frame. Marco coughed awkwardly and averted his eyes so he didn't have to make any eye contact. At least she was dressed...

"Marco? Why are you under my bed?"

Hah! You just gotta love that cliffhanger! Anyway, I will continue this so don't worry I just didn't want to make it too long. Sorry MaFx98 but I gotta keep these under 3000 words. See you later Brochachos and Brochachas!
