"I have made my decision." Mecha sonic said
"wonderful." Z said "what is it?"
"I choose for us to stay." Mecha sonic said "Eri is more familiar in this environment and the doctor is very dangerous."
"understandable." Z said "I'll get your stuff and build you a house."
in an instant there was a house with Mecha sonic's sunflower in the garden and a garage with a bunch of decent condition badnik parts
"it's amazing!" Mecha knuckles said "thanks!"
"you're welcome." Z said "also Eri has a room with proper clothes in there so make sure she's wearing something other than that dirty cloth people call a dress. Feel free to give me a call just say "Z I need help" and I'll be listening."
And with that Z stopped talking
"what kind of name is Z?" Metal Mach 3.0 asked
"don't be rude." Silver sonic said before they entered the house
they had just about everything they could need
"it's really nice." Eri said "but do I really deserve this?"
"of course you do." Metal Mach 3.0 said
"but I'm a curse." Eri said
"who told you that?" Mecha sonic asked
Eri was silent
"overhaul told you that didn't he?" Mecha sonic asked
Eri nodded
"I should have slowed that spin dash so he could feel all of that pain." Mecha sonic said "your power isn't a curse it's a blessing."
"really?" Eri asked unsure of the truth of that statement
"of course it is. think of all the good you could do with such a power." Mecha sonic said "heal the injured, restore limbs maybe even revive the dead."
"really?" Eri said "I can be a hero?"
"of course you can." Mecha sonic said " if that's what you want."
"I'm not sure... I mean those heroes probably got hurt trying to save me..." Eri said
"if they got hurt trying to save you that means you were worth saving." Mecha sonic said "never forget that and don't let anyone tell you otherwise."
"okay..." Eri said
"now then let's go get you dressed up." Mecha sonic said
later
"HOW THE HEL-CK DID YOU BURN WATER!?" Silver sonic asked as he watched Mecha knuckles try and fail at making Eri a hot chocolate
"I don't know it just caught on fire!" Mecha knuckles said as he put out the fire
Eri despite her being haunted by overhaul's words couldn't stop herself from laughing
these guys were really silly!
"it's nice to hear you laugh miss Eri." Sigma said while grabbing some more screws to rebuild a another Scrapnik "would you like to help me?"
"sure!" Eri said as she followed sigma
the two went to the garage
Eri saw a bunch of parts lying around and decided to try and build her own Scrapnik
that's when she saw a nearly mint condition shell for a Mecha chao
"mister sigma what's this?" Eri asked
"that was a prototype for a Mecha chao." Sigma said "the doctor realized that organic chao would know this one would be a fake so he got rid of it."
he began to work on putting an Ai in the chao
"the doctor?" Eri eventually asked
the E100 unit was silent for a moment
"our creator." Sigma said "every single Scrapnik was originally made by him and was made to do horrible things. But then when we served our purpose we were cast aside and left to rot. I decided that wasn't the way to go so I began to repair and grant freedom to my fellow Scrapniks."
"so you're a hero?" Eri asked
"I'm too humble to think of myself like that." Sigma said "Mecha sonic though is a hero. Even if that wasn't always the case."
"what do you mean?" Eri asked
"Mecha sonic as the name suggests is a robotic version of sonic the hedgehog: the fastest thing alive. however, he was defeated by both sonic and Mecha knuckles's organic counterpart knuckles the echidna." Sigma explained "And then he washed up on Scrapnik island and he became the island's guardian after I repaired him."
"then what?" Eri asked
"and then sonic and his friend crashed on Scrapnik island." Sigma said "and while trying to help them Mecha knuckles and Mecha sonic fell back on the original programming however, sonic helped Mecha sonic from being melted in a furnace, and young miles helped repair Mecha knuckles and helped fully remove the original programming from the both of them."
"wow..." eri said
"wow" indeed. could you pass me that screwdriver?" Sigma asked "I need it to put in the new circuitry."
Eri handed him the screwdriver
"and with a little of that... there it's done." Sigma said "they should act like a chao."
he activated them and they immediately turned to fire Eri
and they immediately gave her a hug
"it seems to be successful." Sigma said
"I'm gonna call you deku." Eri said
later that evening
Mecha sonic had just put Eri to sleep was pondering something
"hey Z I need some help." Mecha sonic said
"what is it bud?" Z asked
"what villains could pose a threat to the world?" Mecha sonic asked
"let's see here... the league of villains... all for one...maybe Yotsubashi Rikiya aka re-destro." Z said "why do you ask?"
"can you give me the locations of them?" Mecha sonic asked
"...fine but be stealthy about Re-destro. he has a good public image." Z said catching on immediately
"gotcha ya." Mecha sonic said
later
Mecha sonic had destroyed the league of villains and anyone connected to them
flashback
"toga, twice what happened?" Shigaraki asked
"we were attacked by-" toga began before mecha sonic's hands went clean through her and twice's stomachs before they dropped dead to the ground
"Alright you got some serious balls!" Dabi said before throwing a massive fire ball
Mecha sonic deflected it and fired a point blank energy blast a Dabi's face taking his head off
then Mecha sonic turned to face shigaraki
"who are you." Shigaraki stated
it wasn't a question it was a demand
"your executioner." Mecha sonic said
"BULLSHIT!" Spinner said before trying to attack Mecha sonic from behind
"Die." Mecha sonic said before unleashing a chaos blast, evaporating the building and everyone else inside
Mecha sonic fled before the heroes could arrive
at that time all for one felt his successor die.
flashback end
and then he leaked a video of re-destro torturing a man before destroying the nomu factory
and now he was on his way to all for one
...his last target
and then everyone can rest a bit easier
he teleported into his cell
"who are you?" All for one asked
"I am Mecha sonic." Mecha sonic said "and I'm here to eliminate you."
"that's hilarious." All for one said "too bad it's nothing but a bluff."
"ask your successor if I'm bluffing." Mecha sonic said
all for one frowned
"so you're the one who did it." All for one said
"correct." Mecha sonic said
"how?" All for one asked "he should've decayed you on contact."
"who said he had the chance?" Mecha sonic asked "now then time to die."
Mecha sonic stepped forward and put crabmeat claw through the top of all for one's head
"Z make sure he can't regenerate." Mecha sonic said
"on it." Z said
and then Mecha sonic teleported back home
back at the house
sigma was working on a Scrapnik when Mecha sonic teleported in
"mecha... why is your claw covered in blood?" Sigma asked
"I... "dealt" with some threats." Mecha sonic said
"are you going to tell Eri about this?" Sigma asked
"...are you?" Mecha sonic asked
"what she doesn't know can't hurt her." Sigma said "you should clean that blood off though."
Mecha sonic cleaned of the blood (which took like 20 minutes) before turning on the tv
it was a news report of the murder he had committed
"this just in the villain known as all for one has been found dead in his cell." The news reporter said "the villain was all might's last opponent before the hero's retirement and was quite formidable. Despite this he was killed by an unknown assailant. We have the security footage of his cell at the time of the murder."
(they work fast.) Mecha sonic thought to himself
the footage showed a cloaked Mecha sonic shoving his claw hand through the top of all for one's head
"so that's where you've been." Mecha knuckles said "murdering super villains."
"tell Eri and I will tear off both of your arms." Mecha sonic said before turning off the tv
"not planning on it dude." Mecha knuckles said before walking off
the next day
Eri woke up and got dressed before going downstairs and seeing the Scrapniks attempting to make pancakes
"hello Eri." Mecha sonic said "we did our best to try and make you pancakes."
Mecha sonic handed her a plate with a pancake that was extra crispy without being burnt
"thanks dad." Eri said sleepily
Mecha sonic almost crashed right then and there
meanwhile
principal nezu was watching the video of all for one's death on repeat trying to see anything useful
but he couldn't the only thing of note was the crab claw arm that killed him
and then he remembered something
Eri was taken by a group of robots or at least a group of people with quirks that made them into robots
if any of those robots had anything to do with this they might be able to do a full scale search and save Eri
so he decided to call Izuku Midoriya, Mirio Togata and Tamaki Amajiki
later
"so you think one of the people who took Eri killed all for one?" Midoriya asked
"yes." Nezu said "and they might not be people with quirks but actual robots."
"with how much emotion they showed I doubt it." Mirio said
"now does this crab claw look familiar?" Nezu asked
"yeah some of them had them for arms." Midoriya said "but none of them had that body type they were all too small."
"actually one of the metal hedgehogs had it." Tamaki said "the tallest one."
"really?" Midoriya asked "I knew he had a buzzsaw for a foot maybe he can change his parts at will-"
Midoriya began to mumble
"if he can then we have our man." Nezu said "I'll have Mei hatsume build something to track them down."
as if on cue Mei hatsume barged in
"so sorry for interrupting but I've been getting odd energy readings." Mei said before showing them a location in a forest "with energy like this you could power an entire city for a year!"
"I think we found them." Nezu said
later
after a good 20 minutes of explaining to Eri that it was okay for her to call Mecha sonic dad things were finally starting to settle down
"uh Mecha sonic?" Mecha knuckles said
"yes?" Mecha sonic answered
"why is there a group of heroes outside?" Mecha knuckles asked
Mecha sonic looked outside and there was in fact a group of heroes outside
"sigma get Eri upstairs." Mecha sonic said "this might take a while to explain."
"assuming they are willing to talk to you." Sigma said
"Mecha knuckles, metal, silver Sonic, you're with me." Mecha said "hey Z I need some help."
"what's up boss?" Z asked
"I need something in case things go south." Mecha sonic said
"I'll whip something up." Z said
"what's going on dad?" Eri asked
"there are heroes outside who probably think I'm doing terrible things to you." Mecha sonic said
"but you've been nothing but nice to me!" Eri said
"they don't seem to think that." Mecha sonic said "I need you to go upstairs with sigma and the others."
he turned to Boris
"and Boris... protect her with your life."
Boris did a little salute before going upstairs
Mecha sonic and the others went outside
"wow so I guess you ain't a bunch of bitches." A blonde boy with grenade gauntlets on his arms
"we'll cut straight to the chase where is Eri?" The man with red glowing eyes identified as eraser head asked
"she's upstairs after having a breakfast of pancakes." Mecha sonic said
"that's...manly?" A red head boy said clearly not expecting that response
in fact none of the heroes were
"why do you want her?" Eraserhead asked
"to shower her with love and affection because clearly no one has." Mecha sonic said
the heroes were clearly not expecting any of these responses
"why did you kill all for one?" Eraserhead asked
"because he's a supervillain. it's not that complex." Mecha sonic said "if anyone of you had the balls to do you would."
"those are fighting words!" The blonde said his palms exploded
"bakugo cease this behaviour!" A teen in armour said
"idia I don't think he's gonna stop." Deku said
"so are we going to fight them or not?" Bakugo asked Eraserhead
"they seemed to care about Eri a lot but she needs to monitored." Nezu said before Eraserhead could say anything
"we are the only ones immune to Eri's power." Mecha sonic said "therefore we are the best suited to this task."
just then a eggrobo threw a drone with a ton of bullet holes in it out the window
"my baby!" Mei hatsume said picking up the drone
"really?" Mecha sonic asked "you sent a spy drone."
"well you shot it." Nezu said
then Eri peered out the window and shot the drone again
"Sigma did you give Eri your gun!?" Mecha sonic asked
"SHE USED PUPPY DOG EYES IM SORRY!" Sigma yelled "she already dumped a whole clip of ammo into the drone she just wanted to get one more shot in!"
"oh my god I need to have words with her later." Mecha sonic said "now where was I-"
then Mecha sonic got cut off by bakugo punching him in the face
"a shame." Mecha sonic said "I'm gonna have to make you regret that."
"hey boss I got the boosts! You're gonna love this!" Z said
suddenly 2 chaos emeralds appeared in silver sonic's and metal Mach 3.0's hands while Mecha knuckles got two sol emeralds
Mecha sonic got 3 chaos emeralds
"If you're so eager to throw away your safety..." silver sonic said
"THEN SO BE IT!" Metal Mach 3.0 yelled before they shared the power to achieve a semi super (and a semi burning) form
"this power!" Deku said trying to hold himself in place
(this heat is on par with endeavour.) Eraserhead thought to himself
"WE'LL CRUSH YOU!!!" Mecha sonic yelled before slamming into Eraserhead sending him flying back
once Eraserhead came to a stop he then realized that Mecha sonic didn't have a quirk
"they don't have quirks they're robots!" Eraserhead yelled
"no shit Sherlock!" Metal Mach 3.0 yelled before slamming into bakugo with a V. Maximum overdrive causing the hero to cough up some blood
"kachan!" Deku yelled
"you call him "kachan"? That's hilarious." Mecha knuckles said
a red and white haired boy tried shooting ice at him only for the ice to melt around him
"buddy what made you think that was going to work?" Mecha knuckles asked
"...I got nothing." The boy said
"fair enough." Mecha knuckles said before knocking him down with a punch
"please stop!" Eri yelled from the window "they're really nice to me and I don't want them to get in trouble for hurting you!"
"don't you mean you don't want us to hurt them?" Bakugo asked
"did that last hit give you brain damage?" Eri asked to which metal Mach 3.0 laughed at
he stopped as soon as Mecha sonic gave him a glare
"Eri you don't really understand what's happening here." Nezu said
"what I understand is that a bunch of "heroes" are trying to take me away from my new family!" Eri said
"alright who gave Eri sass lessons?" Mecha sonic asked to which Mecha knuckles and metal Mach 3.0 raised their hands
"you two are doing the dishes for the next week."
"Worth it." The two said
"so please leave!" Eri yelled before shutting the window
Z teleported the emeralds out of them causing them to power down to the normal forms
"you heard her! Get off our lawn!" Metal Mach 3.0 said
Eraserhead walked forward towards Mecha Sonic
"I'm going to try to get half custody of her." Eraserhead said "that's a promise."
"key word try." Mecha sonic said
and with that the heroes left
then Eri ran outside
"is it over?" Eri asked
"for now." Mecha sonic said
"yay!" Eri exclaimed hugging her adopted father
and no one was going to separate them
some aftermath and some explanation stuff
Mecha sonic somehow remained in full custody of Eri because the night before he read up on every in date law book and managed to win
Eri still visits U.A however and was pretty impressed by the festival
Z overloaded all for one's healing quirks with chaos energy preventing them from working
Aoyama thanked Mecha sonic for killing all for one in secret when they were at the festival
Eri eventually became a hero and the mechanical chao she had became a weapons storage
Z altered the Scrapnik's code which allowed them to kill in the first place
and that's it for now. I would love to see your own twists on this maybe have Eri be saved at the beginning of the series instead of the raid
see ya!
