Sonic and his friends were running through eggman's base

the mad doctor had stolen the chaos emerald tails had and now they were trying to get it back

however, the moment they broke in the alarm went off and a horde of badniks showed up and tried to to stop them

"What the heck is egghead planning this time?" Sonic asked as he smashed a buzz bomber

"I'm not sure sonic all I know is that he has all 7 chaos emeralds!" Tails said as he looked at his chaos emerald tracker

"well then we better hurry!" Sonic said

suddenly a swat bot tried to attack him but was quickly dispatched by amy with her hammer

"amy! Good to see you!" Sonic said

"hey sonic!" Amy said "after this you want to go out on a date?"

"sorry ames I'm busy!" Sonic said

"okay maybe some other time then." Amy said slightly disappointed

"get down!" Knuckles yelled as he pushed amy out of the way of a giant motobug

"thanks knuckles!" Amy said

"hey knuckles didn't expect to see you here!" Sonic said

"eggman has the chaos emeralds of course I'll be here!" Knuckles said as he crushed a badnik with his bare hands "let's keep moving!"

they continued to run through the base

"why do you even try?" Tails asked amy as she slammed another badnik

"what fo you mean?" Amy asked

"i mean why do try asking out sonic he says no every time." Tails said

"because me and him a destined to be togethe!" Amy said "my tarot cards said so! It's the whole reason i went to little planet!"

"didn't you get kidnapped by metal sonic there?" Knuckles asked

"sonic told you about that?!" Amy asked

"he told me when we first encountered metal sonic." Knuckles said

"same here!" Tails said

"well it doesn't matter he saved me!" Amy said

"imagine this plot twist: your tarot cards were talking about metal sonic." Knuckles said

"why would i be with him!?" Amy asked "besides the fact he looks like sonic!"

"well he never harms you." Knuckles said as he threw a badnik into a wall

"he kidnapped me!" Amy said

"but you were unharmed." Tails said "and I don't think he was sentient back then."

suddenly they heard a voice

"TARGET AQUIRED!" A robotic voice said

suddenly sonic was tackled by...

"Metal sonic?!?" Sonic said "wait...NEO METAL SONIC?!?"

"HAHAHAHAHA!!!" A familiar voice laughed

standing in front of a strange device was doctor eggman

"Eggman!" Somic said while trying to fight off metal sonic

"I've upgraded metal with the ability to turn into his neo metal form at will!" Eggman said "now you can't win!"

"what do you plan to do with the chaos emeralds?!" Knuckles asked

"nothing that involves you rodents! So buzz off!" Eggman said "metal sonic attack!"

neo metal sonic threw sonic at tails before slamming knuckles into the ground

eggman began to activate the control panel

"boss aren't we forgetting something?" Cubot asked

"yes usually something we forgot about comes back and ruins our plans." Orbot said

"nonsense!" Eggman said "nothing can go wrong!"

Suddenly amy jumped onto the platform eggman was on and slammed the control panel with her hammer

"you idiot!!!" Eggman said as he jumped off the platform

then a massive portal opened up and sucked all of the chaos emeralds in to it sending them to the unknown

"the emeralds!" Sonic yelled

the pull of the portal began to pull amy in

amy grabbed on to something but her grip was slipping

"AMY!" The heroes yelled

suddenly metal sonic grabbed her and began to try and get her out of there his jet boosters going on full blast

"metal what are you doing?!?" Eggman asked

however the pull of the portal was too strong and it pulled them in, sending then to an unknown location

"METAL SONIC!!!"

"AMY!!!"

the portal closed behind them

Sonic was pissed

he walked over to the cowering eggman

"Alright egghead what were you planning!?" Sonic yelled grabbing the doctor by the collar "where does that portal go?!?"

"I don't know!" Eggman said "I originally made it to find new energy sources for my machines! I upgraded metal to deal with anything there but then you rodents showed up and ruined everything!"

"well make another machine then!" Sonic said

"I can't! I need the chaos emeralds in order to power it and they went into the portal! Unless you are willing to give me the master emerald instead." Eggman said Giving knuckles a grin

"like hell we're doing that!" Knuckles said

"knuckles please it's our only chance to get amy back!" Tails said

knuckles was silent for a moment before sighing

"fine! But any funny business and I'll crack your skull open!" Knuckles said

"deal." Eggman said

"I'll make sure he doesn't try anything." Tails said

"first things first we need to make a sanitizing pod we don't know what diseases miss rose could get sick with while she's there." Eggman said

sonic was about to punch him but was stopped by tails

"no he has a point." Tails said "we don't know where they went there could be diseases there that we have no defence against."

"fine." Sonic said

"alright let's get to work." Tails said

while tails was looking at the blue prints eggman made as eggman was explaining it knuckles stayed with sonic

"she'll be okay." Knuckles said

"if she isn't i'm killing him." Sonic said

"you finally realized you like her?" Knuckles asked

"no she's just a friend ." Sonic said

"you sure?" Knuckles asked

"don't talk to me about romance with the weird romantic tension you have with rouge." Sonic said

"...shut up." Knuckles said

"anyway I should probably tell cream that amy won't be able to attend her tea parties anytime soon." Sonic said

"you do that i need to get back to angel island before rouge steals the master emerald before we are able to use it." Knuckles said before leaving

(amy please be okay.) sonic thought to himself before leaving


When amy awoke she was under some rubble

"where am i?" Amy asked herself before hearing a beep

she turned around and saw metal sonic in his normal form

"you saved me...why?" Amy asked

metal sonic's eyes had text appear on them which said:

"i still remember that day in the snow."

Amy was confused for a moment before remembering what he meant

"well thanks." Amy said "i do too by the way."

she began to move the rubble around her before finding the chaos emeralds

"okay let's put you in here for safe keeping." Amy said as she put the chaos emeralds in her purse

soon they got out of the rubble and saw a odd sight

a blonde man im a super hero costume and an old man were fighting a man with a giant arm with a group of people in hero costumes nearby

the man with the giant arm noticed her

he prepared an attack

"quickly dodge and counter!" The old man yelled

"not everyone's so fast!" The giant armed man yelled as he lunged for amy

amy simply caught the punch with one hand

everyone was stunned

"you know it's rude to attack people who aren't fighting." Amy said before lifting him up and slamming him on the ground

"do you have any idea who i am?" The man asked angrily as he got up

"I know you're a jerk." Amy said as she pulled out her hammer

"ma'am please leave! it's too dangerous!" The blonde man said

"I am all for one, the demon king!" All for one said

amy simply laughed

"if i had a nickel every time i heard something like that." Amy said

suddenly metal sonic lunged at all for one and tackled him into some rubble

"you dare?!" All for one yelled as he tried to punch metal sonic

metal sonic activated his black shield negating the damage

"A shield!!?" All for one said

metal sonic retaliated with a knuckles slam cratering the ground under him

he then began to charge up a chaos blast

amy quickly recognized the attack and yelled:

"everyone run!"

sensing the danger the blonde man the old man and the group of people nearby fled as amy got away too

the attack was released and a huge wave of energy made the crater even deep then it was

all that was left of all for one was his head

(This is impossible!) all for one thought as metal sonic put his foot on his head

amy walked over

"you done?" Amy asked

metal sonic grabbed amy's hammer and slammed it on all for one's head

All for one's last thought was:

(if Shigaraki and I combined bodies would it be enough? ...No this is far beyond that level of strength)

"you didn't have to kill him." Amy said

"FREEZE!!!" A male voice said

they turned and saw a red haired man

"you are under arrest for vigilantism." The red haired man said "come quietly."

"what?!" Amy questioned "we were just trying to help!"

"doesn't matter you and your robot friend used your quirks illegally." The red haired man said

metal sonic then activated his speaker and played an audio clip

"You'll never catch me, krabs! Not when I shift into MAXIMUM OVERDRIVE!"

in an instant metal sonic grabbed amy and flew off

"what the hell just happened?" The old man asked

"I have no clue." The blonde man said

"What the heck were those guys talking about?" Amy asked "quirks? vigilantism? I don't get it!"

metal let out a beep in response

soon they landed in a forest

"where the heck are we?" Amy asked

metal sonic's eyes showed some more text

"we are in a different world."

"a different world?!?" Amy asked "like blaze's dimension?!"

"correct. The doctor was using the emeralds to open a portal to find new power sources for his machines."

"That jerk!" Amy said

"I propose we work together in order to survive."

Amy thought about it for a moment

"...fine." Amy said "let's just find something to eat."

Izuku Midoriya was absolutely stunned and horrified

granted itbhad been a stunning and horrifying day

he had seen all might fight one of the strongest villains in the world: all for one

and when all for one tried to attack a civilian that was in some rubble said civilian grabbed his arm with one hand and slammed him into the ground like his was a sack of potatoes

then a robot that would make mei hatsume swoon jumped out of the rubble and tackled all for one to the ground before destroying most of his body followed up by killing the villain

"what...the...fuck just happened?" Midoriya asked

his fellow classmates turned to him shocked at what he just said

"you know it's bad when Midoriya swears." Kirishima said

Overhaul was watching the news

All for one had been killed

"chronostasis. Get Eri ready we are going to put the yakuza back on top." Overhaul said

"what about the two who beat all for one?" Chronostasis asked

"they will meet the same fate as anyone who tries to stop us." Overhaul said "dead."


Shigiraki was furious

some pink quilled bitch stopped his sensei's punch with just one hand and then a blue gum ball son of a bitch killed him

"what do we do now!?" Toga asked

"We lay low for a while." Shigiraki said "and when get the Chance we kill that girl and destroy that robot!"


Later at HPSC headquarters

"as I'm sure you all heard all might is retiring." The president said "and now the public knows about his weaker form."

"i have an idea." A higher up said "that girl and the robot."

"the one that killed all for one?" Another higher up asked "no way they're vigilantes!"

"that may be true but the girl caught all for one's fist with ease and that robot was able to completely neutralize his healing quirks." The previous higher up said "at the very least we should use the robot as a new blueprint for a new symbol of peace robot."

"it is a good idea." The president said "have the police force search harder."

little did they know this was the beginning of the end for the current world of heroes and villains

everything was about to change


About a week later classes were back in session at UA

"so anything about that robot and that girl?" Kirishima asked

"no nothing." Denki said

"Why do you care about that shitty hair I'm way stronger than them!" Bakugo said

"press x to doubt." Denki said

"WHAT WAS THAT PIKACHU?!?" Bakugo yelled

"what? it's true dude I mean they killed somebody who was giving all might a hard time!" Denki said

"it doesn't change the fact they killed someone!" Iida said doing a hand chop motion

"i say it's a good thing!" Aoyama said

"are you insane!?" Iida asked

"All for one probably had a plan to escape prison should he have gotten captured!" Aoyama said

then aizawa walked in

"alright class nezu told me to tell you all if you see the two who killed all for one to bring them here rather than the police if you are alone." Aizawa said

"why?" Yaoyorozu asked

"nezu wants to talk to them without government interference." Aizawa said "so make sure you bring them here."

"Right!" The class said

i'm honestly baffled at the fact that there are no sonic x my hero academia fics with metal sonic as one of the main characters

Sprinkle in some metamy some eri adoption some all for one murdering and some good old fashion "overhaul gets his ass whooped by an overpowered character" and we got ourselves a potential disaster on our hands

that's it for now see you next time
