"Hmmm.. hmmmm.. hmmm.." Yuki-onna hummed to herself as she walked through the forest, a massive blizzard whirling around her like an insane cyclone..  multiple Class 1-B students lying in the snow.. too cold to even move more than a few inches.

"D..Dang... it.. it's... too.. " Muttered Velma.. her body covered in frost as she lay in on her stomach.. shivering. "What the hell.. I feel.. sleepy.."

"Oh don't you worry little ones.. all of you just sleep now.. yes yes.. sleep and never wake up.." said Yuki-Onna with a twinkling laugh. "Oh.. you adorable ones... how adorable you all are..."

"DIMENSION CANNON!!!"

Yuki-onna's eyes widened as she turned into a flurry of snow and whirled away, barely dodging a powerful energy blast..

"Oh..? What was..?"

Bella charged in,  her eyes glowing as her battle programs analyzed her opponent at immense speed, formulating multiple battle plans in her head.

"So.. you are a yokai as well.." said Bella as Momo and Ochaco followed her out of the frozen woods.

"Ohh...." Yuki-onna reformed into her solid form, smirking. "An Android right.. artificial beings capable of so much..  to think humans can actually progress so far without using magic.."

"Preparing Combat mode.. Bella Unit fighting parameters active.." said Bella as her arms both morphed into plasma cannons. "Battle time speculating to take around... 3 seconds.."

"3 seconds!?" said Yuki-onna, her eyes flaring with anger. "You really believe it will be THAT easy to defeat me?"

Bella's plasma cannons began to glow as modifications were made.. and large red heated lights burned from their barrels... the snow around Yuki-onna started to melt as she fell to her knees gasping.. barely able to move.

"Wh.. WHAT ARE YOU DOING!?" Yuki-onna stammered.

"I analyzed your biology.. you are dependent on Cold for survival.. as such.. immense heat  can weaken you considerably." said Bella in a calm analytical voice.  "I modified my cannons to become microwave emitters which throw out targeted heat..  as such.. you were already defeated the moment these heat emitters hit their mark.."

"D..damn.. you.." Yuki-Onna groaned as she fell to the ground.. going unconscious..

"She was easy." Momo stammered.

"No.. actually we were just lucky that I happened to have the perfect weapons system to counter her type of abilities." said Bella. "If somebody else other than me had been here, I don't think we'd be so lucky.  The heat I used had to be at a radioactive level to work, so Shoto-kun's flames wouldn't have worked...  and I had to be careful to contain the radiation so I wouldn't give the other students radiation sickness."

"Bella... you're so carefree a lot of times.. but.." Ochaco stammered. "You're.. actually very good in a fight.."

Bella winked and held up a piece sign. "Well of course! I am the number one Bella-chan! Android helper to Shock Therapy!! It takes a lot more than demons to take me down!"

"We should gather up these students and get them back to camp.. " said Momo. "Bella.. how many can you carry?"

"All of them at once if you roll them all up in a big ball!" said Bella cheerily.

"In a big ball?" Momo stammered.

Moments later back at camp, Tiger was still in the middle of fighting the multi armed oni... multiple other yokai knocked out around them..

"PREPARE TO-!" The oni began.. right before a giant snowball filled with Class 1B students exploded down on top of him.

"GAAAAAHHH!!" the oni stammered as he staggered out of the snow and was suddenly kicked straight in the face by Bella, who flew in like a kung fu wizard.

"WHAAACHAAAAAAAAAAAAA!!!" Bella roared, taking up a kung fu pose. "Crouching android.. Hidden robo Dragon!! hiiiiyaaaaaaaaahhh!!'

"Uhhh... hey." said Tiger.

"HELLLOOOOO!!" said Bella as Ochaco and Momo came out of the woods and the 1B students groaned on the ground in a pile of snow. "I brought the kiddies!"

"Grrroooaaa.. nice!" said Tiger. "It's good you're here at least, where is Violet?!"

"She's dealing with one of the weird yokai that turned up.. I also dealt with one of them." said Bella. "Where are the others?"

"As far as we know, they are still back at the main building!" said Mandalay. "I've been using my Quirk of one way telepathy to contact all of them... however there's a problem.. we're missing Midoriya.. he's gone to get my nephew who's missing.."

"M.. Missing!?" stammered Bella. "EEE! If I lose a single student, Narina won't give me head pats!! ACTIVATING TRACKING SYSTEM!!!!"

Bella froze stiff, and her eyes glowed green. "locating GPS tracker on Midoriya-kun..."

"GPS tracker...? WAIT A MINUTE WHEN!?" stammered Ochaco.

"I fed it to you ALL during dinner!" said Bella cheerily.  "Don't worry, it'll last 12 hours before digested.."

"Did... you tell Narina you were doing that?" muttered Mezo.

"NOPE!" said Bella cheerfully. "But I'm sure she wouldn't mind!"

"Of course not.." stammered Momo as a sweat drop trickled down her forehead.

"Alright.. located... try not to wait up!!! Bella super chasing tracking mode... OOOOOOONNNNNNN!!!!!" Bella dashed into the forest with explosive speed, leaving a massive dust cloud behind her.

"She is really adorable and terrifying at the same time.." muttered Mandalay.

A ways away.. on a cliff overlooking the forest, Kota looked over the forest.. unaware of everything going on.. staring with his usual grumpy look as he seemed to consider the world around him..

"Stupid super human society.." muttered Kota. "Everyone just wanting to get famous for money and a gravestone over their heads.."

Kota continued to stare outwards for a moment... but as he did.. a shadow walked out from behind him.

"Heheheheheh" A voice chuckled as a large man made his way out of the shadows. "What? I wanna go wild and all I find is one measely kid? What a joke."

Kota blinked and turned around, his eyes started to widen.. as fear etched onto his face..

it.. couldn't be..

The man.. wore a muscle shirt.. he was tall, hulking and had sandy hair.. and one of his eyes was gone.. scarred with but one false eye imbedded there..  He grinned and stared down at Kota.

It was a villain.. and not just any villain..

He remembered that face..  the face of the one that killed his parents..

"y.. you.. it's you.." stammered Kota, tears trickling from his eyes. "M.. Mama.. Papa... no.."

"Hehehehe.. AHAHAHA! I remember you!!" roared the man, the villain known as Muscular. "You're that kid... whose parents decided to take my eye before I smacked em down ta hell!! HAHAHAHAHAHAHAHAH

Muscular raised a hand. "Good bye kid.. nice to know I got a little snack in before the real main course..."

"KOOOOTAAAA!! RUUUUNNNN!!"!

Izuku exploded out of the forest in Full Cowling form.. hurling a fist directly at Muscular. "SMAAAAASHHHHHHHHHHHH!!!"

"WHAM!!" Izuku's fist was met with barely any damage at all as Muscular shrugged off the hit immediately, glaring at Izuku. "EHH!? Ya interuppting.. PUNY BRAT!?"

"Y.. You!?" stammered Kota. "M.. Midoriya!?"

"KOTA!! GO!! I'LL HOLD HIM OFF!!!" Izuku stammered.

"HOLD ME OFFF!?" roared Muscular with laughter as he raised an arm, and suddenly strings of muscle fiber grew from his arms.. his legs.. his chest.. and covered his entire body.. until ginormous skinless bulging muscles were wrapped around his body.. turning him into a hulking giant.

"h.. he can control his muscles!?" stammered Izuku as Muscular loomed over him.

"TAKE THAT!!!" Muscular roared, hurling a fist down at Izuku and Kota.

Izuku grabbed Kota and leaped out of the way as an entire segment of cliff was destroyed by that single punch.

"H.. He's powerful!" stammered Izuku. "Damn.. if we merely try to run.. he'll catch up... which means.."

Izuku landed on the ground with Kota. "KOTA!! JUST GO!!!!! I'll fight him myself!! Just get help!!!"

"GRRRRRAAAAHHHHHHHH!!!" Muscular emerged from the dust, grinning like a madman, clenching his ginormous arms, prepared to absolutely kill. "Heheheheheheh.. you're pretty quick little hero in training... all the more pleasure I'll have in ripping you limb from limb.."

"Why... why? He's going to lose.. he's going to die?" stammered Kota tearfully. "What does he get from helping me..?"

"RRRRRRROOOOOOOOAAAARRRRR!!" Muscular leaped forward hurling forth a powerful blow..

"I.. don't have a choice... i have to use... it at 100 percent!" stammered Izuku... "SMAAAAAAAAAAASSSSSHHHHHHHHH!!!"

Izuku met Muscular's punch with his very own.. managing to hurl past the monstrous villain's fist and smash his own fist right into the villain's chest..

But the shockwave of the attack was immediately swallowed up.. somehow, the multitude of muscles was able to  contain the brunt of the force..

Izuku stared in shock as he fell to the ground.. his entire arm limp, his bones shattered . "H.. How.. ? Th. that was a blow equal to All Might's... that.."

"Interesting kid!!" said Muscular with a grin as he stood mercilessly over Izuku. "But ya nearly killed yourself pulling that off!! HAHAHAHA!  But if that's all you've got.. then you're toast..  why risk your life again.. ? Why not just step aside.. ?"

"I won't... " Izuku gasped, staggering to his feet.

Kota stared with horror as he noticed Izuku's limp arm. "N.. no... don't... don't kill him... no.."

Someday Kota... someday you'll find that somebody who'll do anything to save your life.. with no wish for anything in return... someday.. you'll meet him.. your hero..

Kota's eyes welled up with more tears as he shut them. "S.. Save me.. Midoriya-kun.. BUT PLEASE DON'T DIE!!!!"

"I won't.. let them get you... KOTA!!" Izuku said, breaking out into a determined smile.. as Muscular raised a fist in preparation to pulverize him...

"DIEEEEEEE!!!" Muscular roared hurling down a devastating punch.

"DIMENSION... CAAAAANNNOOOOONNNNNNNNNN!!!!!!!"

https://youtu.be/NaVT22gcrMI

"BOOOOOOMMMMMMMMMMM!!!" A powerful plasma blast exploded against muscular, obscuring him in smoke.

Bella landed in front of Izuku and Kota..

"B.. BELLA CHAN!" stammered Izuku.

Bella glared at the cloud of smoke in fury as Muscular emerged unharmed, her eyes glowing green with tremendous fury.  "You.. dare hurt Master's students so cruelly... I... I... I WON'T FORGIVE YOU!!!! I WILL DISMANTLE YOU!!!!"

"Who the hell are you!?" growled Muscular. "OUT OF THE WAY!!!!!"

Muscular hurled a hand down at Bella with the intent of smacking her out of the way.

Bella dissapeared in a blur of speed and appeared above Muscular.

"STARLIGHT KICK!!!!!" Bella's leg glowed with bright bluish energy and she sent down a kick so fast, it looked like a shooting star straight into Muscular's jaw.

"KAAAAPPOOOOOOOOWWWWWWWWWW!!!" Muscular was sent skidding back and smashing into the wall of the mountain...

But when the dust cleared and Bella landed on her feet, Muscular emerged from the dust, grinning and popping his neck. "That all ya got!?"

"I see.." said Bella, her irises narrowing and analyzing Muscular with multiple processors. "You're durable.. not on Narina's level.. but.."

"Bella-chan! He's strong enough to take a blow from All Might! Be careful!" stammered Izuku.

Bella smiled back at Izuku. "Don't worry.. Midoriya-kun! Take Kota-chan and leave please!! Leave this one to me!!!"

Bella glared back at the approaching Muscular. "If I had access to the special Combat Armaments in orbit at my world.. I'd be able to destroy him in only 2 seconds.. like how I was powerful enough to fight Zenthis-san.. however.. in this world those armaments aren't present.. so.. I have no choice but to use my other special components.."

"Special Components!?" stammered Izuku.

Bella's eyes flashed and glowed silver now instead of green..  and her hair turned white and wild looking..

"Special Combat Mode: STARLIGHT BREAKER!!" Bella exclaimed.  "I am a special Bella Unit.. manufactured at special request orders from Narina's grandma..  compared to other androids... I am exceptional!!"

"Nice look!!" said Muscular with a laugh. "You might just... NOT BE BORING AFTER ALL!!!!!!"

Muscular hurled a long punch, sending it into a low travelling uppercut that ripped the earth apart as it made it's way towards Bella, a shockwave exploding past the fist from the force alone..

Bella turned into a tremendous burst of speed. "STARLIGHT BARRAGE!!!"

Bella's fists glowed with the same blue energy from before and she let out a tremendous barrage of punches that looked like multiple shooting stars exploding into Muscular's face at once.

Muscular was sent hurtling back, but caught himself.. a few bruises on his face.

"OI! That actually stung a little.. "Growled Muscular.

"SHOOOTING... STAAAAAAAAAAARRRRRRRR!!" Bella screamed as she suddenly blitzed forward, hurling a jumping energy kick so fast, she turned into a meteor of blue light that blasted straight into Muscular's gut. 

"GGGGGGGGGAAAAAAAHHHHHH!!" Muscular roared as blood spat out of his mouth.

"A Special Energy that doesn't rely on being able to pierce through durability.. or solid armor.." Bella whispered  as she leaped back from the the staggering villain. "That is what happens when I utilize the energy from my power core.."

Muscular grinned and wiped the blood from his chin. "What are you talking about girl..? I'm... STILL STANDING!!!"

Bella narrowed her eyes.. then turned into multiple blitzing blurs of speed.. afterimages appearing all around before she closed in at Muscular's shoulder.

"STARLIGHT PUNCH!!!" Bella hurled a glowing fist at Muscular.

But Muscular was ready now.. he whirled around in just the nick of time and rammed a fist straight into Bella's face. "TOOO LATE!!!"

"PPOOOOOOOOOOOWWWWW" Bella was sent smashing into the earth with a tremendous explosion of dust..

Bella rose from the crater, panting.. a few bloody scars visible on her torn clothes..

"BELLA CHAN!!" screamed Izuku.

"What are you waiting for?" panted Bella. "I TOLD YOU TO RUN!!!"

"HAHAHAHA! They're too worried about you to bother!! Don't worry.. I'll take good care of em once you're dead!!" said Muscular. "And... oh?"

Muscular grinned as he saw several sparking metallic parts visible near the dried blood. "So.. you're the robo-girl I heard about.. that android who assists Shock Therapy.. HAHAHAH you're well built.. for somebody whose not real.."

At the words 'not real' Bella gritted her teeth, her eyes flaring up. "Sh... Shut up... SHUUUUUT UPPPPPPP!!!"

Bella exploded forth in a burst of speed.. but despite her tremendous speed, in an instant, Muscular caught her torso in one hand.

"Wh.. WHAT!?" Bella stammered.

"I'm gonna take a guess... that all your combat capabilities are preprogrammed right!?" said Muscular. "HAHAHA! You may be faster than me.. but the fact you're not even human... MAKES YOU SO GODDAMN PREDICTABLE!!!"

Muscular slammed Bella against the cliff side with tremendous boom.

Bella screamed in pain.. coughing up a combination of blood and glowing blue energy fluid.

Muscular grinned and looked at Izuku and Kota. "THIS is your savior? What is even the point? A hero is supposed to feel empathy for others right? To save people for the sake of saving others.. SHE doesn't do that... This THING only simulates empathy.. it only 'wants' to save you because it's programmed to save you.. IT'S A FAKE!!!"

"Sh.. shut up.. I'm.. not a fake.. I'm.." Bella stammered, tears welling up in her eyes.

"WORTHLESS GARBAGE.. THAT'S EVEN BEEN PROGRAMMED TO CRY!! HAHAHAHA!!" Muscular grabbed Bella's arm.. and ripped it straight off..

Bella screamed as Izuku and Kota looked on with absolute horror..

"Worthless hunk of garbage!!" Muscular growled, throwing Bella and her sparking arm to the ground.  "And you two.. even more worthless..  relying on a pointless machine to protect you.."

"How... dare you.." Kota whispered.

"Eh?" said Muscular.

"Bella-chan.. isn't worthless.." Kota said, glaring up at Muscular. "She.. She cares more.. than anybody!! SHe came... and risked herself to save Midoriya-kun and me.. so what if her body's different.. SHE'S NO LESS ALIVE.... MIDORIYA-KUN AND BELLA-NEE-SAN!!!... ARE BOTH MY HEROES!!!"

Kota shakily held up his hands, and fired a spray of harmless water which splashed uselessly on Muscular. "LEAVE THEM ALONE!!"

"K.. Kota!" stammered Izuku.

"Th.. That's right.. " Bella rasped.. staggering to her feet.. her body sparking from her immense damage, and glaring up at Muscular.. "Don't.. despair.. I. will... protect you..."

"Bella-chan.." sobbed Izuku..clenching his uninjured fist.

"Ehhh?" said Muscular, looking back at Bella. "Still coming back for more? Well.. perhaps you'd be able to beat me.. idiot.. if you weren't a machine... Machines.. are worthless simulations.. they only simulate.. they cannot be... only those that be can surpass their limits. Only humans can surpass worthless instruments like yourself.."

https://youtu.be/XnypjQJV4E4

"Surpass.. my limits..? you think... I can't?" Bella gasped, gritting her teeth as her entire remaining arm suddenly glowed with tremendous burn light.  "Well.. it's a good thing.. I AIN'T JUST A WORTHLESS MACHINE!!!!!!"

Bella exploded with energy.. and the entire forest began to quake as the ground cracked around Bella's feet.

"Wh.. What!?" stammered Muscular as he felt a tremendous pressure explode down upon him.

"You think.. you can just walk around.. and say that I'm garbage.. without bothering to look into my soul? WORM!?" Bella growled as she began to step forward, her power core glowing with immense heat from where it was now visible on her lower back where her clothes were immensely torn.

"HA! Say that once you've learned to improve yourself and surpass your limits! That is what humans do with quirks.. with powers.. with anything worthwhile.. with things that prove you are actually alive!!!"

Bella gritted her teeth. "surpassing my limits.. is not just limited to those.. who were born naturally!! I... I may have been manufactured... mass produced even.. but... I... I SURPASS MY LIMITS EVERY DAY!!! LEARNING... LEARNING ALL I CAN FROM PEOPLE... FROM NARINA-CHAN.. FROM IZUKU.. FROM VIOLET.. NUE.. SORA.. ALL MY FRIENDS!!!!!" 

As Bella spoke.. her power core began to crack.. as energy began to overload past it's own original limits... and Izuku noticed that power seemed to be glittering and flowing INTO it..

"Is.. she absorbing electrical energy from the atmosphere..and friction in the air!?" stammered Izuku. "Wait... BELLA STOP.. YOU'RE GOING TO OVERLOAD!!!"

"SHUT UP IZUKU!!!.." Bella screamed. "I swear... I AM GOING TO SAVE YOU!!!"

"A WORTHLESS MACHINE CAN'T SAVE ANYBODY!!" roared Muscular.

"I AM NOT A WORTHLESS MACHINE!!!" Bella screamed, tears streaming from her eyes and turning to steam as she lunged forward. "I am... A HERRROOOOOOOOO!!!!!!!!!!!!!!!!!!!"

Bella hurled forth a massive energy punch right into Muscular's abdomen in the form of a tremendous uppercut..

"STARLIGHT BREAKER: GALACTICA PUUUUUUUUUUUUNNNNNNNCCCCHHHHHHHH!!!" Bella screamed as something akin to a miniature nuclear explosion occurred..

"AAAARRRRRRRRRRRRAAAAAHHHHHHH!!" Muscular screamed in sheer agony as all his muslcles unravelled unable to take the force or cushion it.. his eyes bulging... as Bella's fist ripped straight into his body.. and shattered his spine to dust.. 

Muscular's body turned into a flopping ragdoll as it whirled into the sky higher and higher.. till finally, it crashed into a mountain top.. and lay uselessly in a crater.. all his limbs twisted in odd angles.. his body permanently disabled for life..

"I... I... did well.. r.. right?" murmured Bella as she staggered back.. her hair returning to normal, as well as her eyes.

"B... Bella...chan.." Izuku sobbed. "BELLA YOUR ARM!!!"

Bella's remaining arm was a tangled mess of wires..artificial flesh and blood.. and sparking metal ligaments.. her fingers twitching as sparks ran down it.. she had exceeded what her body was designed to take.. and it had cost her...

"Eheh.. oops.. "Bella said tiredly as she began to wobble. "I.. guess.. I overdid.. it.."

Bella fell over.. only for Izuku to catch her with his uninjured arm..

"Did.. I save you..?" Bella asked as her right eye's green iris began to flicker with dim light.

Izuku nodded as Kota began to cry.  "Yeah... you are.... A HERO!!"
