Mechanised Hero

Much like the fanfic A quirk of Tanks that takes a similar concept but applies it to fictional mecha and robotic walkers, could be anything from the Power Loader from Aliens (not to be confused with Powerloader the hero) to a Gundam and that's before OfA gets involved in this mess of a quirk.

Just like the A Quirk of Tanks fic the updates will be sporadic and I will try to include various mechs and walkers from shows upon request just nothing insane like putting a Emperator class titan against Bakugo and Iida during the heroes vs villains training session. While it would be funny AF, a 500M tall titan is not going to fit inside the training building.

So to kick things off I will be starting things with:

Chapter 1: did you seriously enhance it?

It was an ordinary day for Mustafu Japan, people went about their days as normal and everything was peaceful, well it was until the resident hero hopefuls got going that was. The sounds of explosions and thudding footsteps filled the air of the local trash heap of a beach known as Dogoba Beach. The entire shoreline was littered with mountains of trash and two boys had made it their mission to clean the area with their quirks.

Now you may be wondering why the police hadn't stepped in yet due to blatant quirk use in public the answer was simple, in both cases the two had medical reasons for their quirk usage.

Katsuki Bakugo, a 17 year old blonde kid with red eyes and more pride than all the lions in Africa, had the quirk called Explosion that worked by letting him sweat nitroglycerin which he could then detonate. The problems arose however with the fact that he had to keep his adrenaline levels up or the explosive substance which permitted even his blood would build up and become lethal to him. Thankfully it seemed to stop being produced around the time he started getting tired allowing him to atleast get some sleep. As a result of this his parents had to constantly try and keep the house high energy and loud to stop any issues arising with their son.

As for the other, they were Izuku Midoriya, a green haired and eyed teen boy the same age as Bakugo with a diamond pattern of freckles on his face. Izuku Ever since the age of 4 had been summoning various SciFi mechs and walkers on a daily basis. If he tried to go a few days without summoning a mech not only would his quirk forcefully summon something massive and energy draining but also leave him in a coma for a day or two. The last time this had happened he summoned his largest creation yet, a 8M tall Gundam, the robot was stripped down and recycled for safety reasons since as he was out cold Izuku couldn't set it to self destruct. Last he heard of it the core was being used to supliment a power plant on I-island and he was getting monthly checks for it that went into a spare account for later in life.

As per the last few weeks Bakugo was detonating the larger chunks of trash free of any smaller ones while Izuku was using his current Mech of the day to move the larger junk away. Today's mech might you be asking? A Hyperion HC-Engineer ARBS-34 also known as the engineer power suit from the borderlands series. Izuku had merely shrugged upon getting it through his quirk. It could be rather arbitrary with what was considered ok to summon and what wasn't at times.

"DIE SHITTY ASS FUCKER TRASH!" Bakugo screamed as he exploded a pile of garbage bags covered in seaweed that surrounded a old rusted pickup truck.

"Gross Kaachan." Izuku sweat dropped as garbage went everywhere.

"SHUT UP MIDORI YOU ROBO BASTARD!" Katsuki shot back, letting off several small explosions from his palms as he did so.

"I still say we should grab you some new quirk suppression cuffs." Izuku deadpanned as he used the small technically a mech gear he was using to drag the rusted pickup out of the rubbish pile.

"AND REPEAT THE SLIME FUCKER?! NO FUCKING THANKYOU!" Katsuki snarled in anger.

A few weeks ago on their way back home they had been attacked by a sludge villain who appeared falling from the sky in a glass bottle of all things. Bakugo at the time had been trying to use quirk suppression cuffs that had just been released by Yaoyorozu Inc the month before for public use. The class had naturally been freaked out about Bakugo being calm for once, one girl even theorising that Bakugo had become so mad that he reached a cold fury where he only looked calm. Due to the cuffs which were hidden up his uniform's sleeve he wasn't able to defend himself and Izuku had already used his one summoned a day on a 3M tall construction mech, needless to say that one along with a user manual was quickly sold to a local construction company called Uraraka Construction for the cost of the manual which they got from a book store for ¥1370. ($12.90 or about that).

Without his usual summon of the day Izuku had a hard time keeping up with the sludge villain as it fled down the street with Bakugo held hostage. Eventually the villain had gotten cornered by a hero patrol and broke the cuffs on Bakugo to start using his quirk against the heroes and gathered crowd. It was at this that things got out of hand with Mt Lady being too large to use her quirk in the streets, Kamiya Woods being useless against Bakugo's explosions and Hydrosis was busy putting out the fires resulting from the explosions and keeping the civilians back.

By the time Izuku had caught up half the street was destroyed and Bakugo was running out of air and almost ready to pass out. Without a single thought for his own safety Izuku charged through the crowd and passed the heroes, running full hilt towards Bakugo who's eyes went wide upon seeing Izuku charge at them. In a swift motion Izuku pulled a heavy maths book from his bag, ditching it at the sludge villain, nailing it in the eye which dislodged not only the eye but a large enough chunk of sludge that Bakugo was able to take a breath.

"THE FUCK YOU DOING DUMBASS?!" Bakugo snarled as he tried to claw his way out of the sludge.

"Saving you!" Izuku shot back as he grabbed Bakugo's arm and started to pull as hard as he could.

Of course things didn't go to plan at all. Before he could even get half of Bakugo free the sludge villain swatted down with enough force to break concrete and send Izuku Flying back several feet.

"I really am pathetic." A new voice huffed in self loathing as the sludge villain froze in fear. "Letting a pair of kids deal with my mistakes. DETROIT SMASH!"

From that day onwards Izuku and Katsuki had been training harder than ever to not only get into UA but for one of Izuku to inherit a quirk passed down in secret for generations, a quirk called One for All. Now they only had two weeks to get the last tonne and a half off the beach before the entrance exams but with Izuku's quirk things were mostly going quickly, there was a slight incident involving a Urban Mech which kept spinning in circles a few days back that slowed them down a bit but they were back on track and Izuku inadvertently earnt himself some internet fame for accidentally recreating a centuries old meme.

"Greetings young zygotes!" Yagi Yoshinori, the skeletal blonde form of All Might called as he walked over, a beach umbrella in one hand and a picnic basket in the other. "Glad to see you two are almost done and uh...you uh got a little something there."

"Gross." Izuku gagged as he used the mech's larger hands to swipe a banana peal out of his hair in disgust.

"QUIT YA YAPPING BASTARD!" Bakugo snapped impatiently as he exploded another large item free, this one a old rusted fridge done in retro 2030s style. Basically it was a big brick and a small as hell folding handle that form fitted to the door until you pushed it in. The fridges had been invented by Elon Musk and quickly fell out of use after people kept having troubles with the door handle.

"If I didn't know you had notice choice but to act like that..." Yagi trailed off in amusement

"COMPARE ME TO FIRE TURD AGAIN AND DIE SHITTY SKELETON!" Bakugo snapped in irritation. It had been a comparison made by Yagi twice already and the explosive bomber hated the comparison with a passion, to him all Endeavour was was a flaming pile of garbage with an ego larger than the sun but the combat smarts of a chipmunk and people skills of a skunk.

"Well... I bought drinks?" Yagi coughed up a bit of blood but quickly wiped it away, disturbingly he was long used to such occurrences happening to him.

"Better not be that Boba shit again." Bakugo scoffed in disgust at the notion of Boba tea. The last time he had some left him feeling sick, he didn't care what the old hag said it had to be poison!

"Uh... Midoriya, do you want Boba?" Yagi coughed nervously as he tried to swap the drinks around.

"What's the worst that could happen?" Izuku shrugged as he made to grab the drink and completely forgot he was still inside the mech harness, the end result? The cup was crushed and Izuku got to feel what wearing Boba tea was like. "That...that happened." He sighed in resignation.

"BWAHAHAHA DAMN NERD!" Bakugo laughed uproarious as he tried not to fall over.

"Just for that Midoriya gets your ice coffee." Yagi deadpanned.

"Ice what?"Bakugo asked in disgust. "YOU SERIOUSLY TRYING TO GIVE ME COFFEE?! YOU DUMBASS THAT MUCH CAFFEINE WILL KILL ME!"

"Uh. He isn't lying." Izuku shuddered, he remembered the one and only time Bakugo tried coffee, the blonde was hospitalized and kept under watch for two weeks when his quirk went into overdrive from the coffee. Poor Mitsuki was blaming herself for months afterwords for almost accidentally killing her son, they were lucky Bakugo only had a few mouthfuls before his body decided to pass out.

"I see." Yagi uttered nervously. "Is it on his medical records?"

"Yeah it is shitty skeleton!" Bakugo snarked.

"Well then if you get into UA it will be easier for Recovery girl to help monitor the situation." Yagi sighed with relief.

"WHAT THE FUCK YOU MEAN 'IF'?!" Bakugo shouted making Izuku sweatdrop. "I AM GONNA BE THE ONE WHO KICKS YOUR SORRY ASS FROM FIRST PLACE!"

"Kaachan please don't." Izuku muttered in embarrassment.

"BY GOSH THAT'S THE SPIRIT!" Yagi shouted as he assumed his All Might transformation with a joyous laugh.

"Hey it's all might!" Somebody called. The trio cringed as a crowd quickly gathered at the edge of the beach.

"CHEESE IT!" Yagi screamed causing the trio to bolt as the crowd of fans descended into the beach like a pack of overexcited puppies.

[Later in the week]

Izuku panted as he stood atop the last of the trash, all neatly packed into a lorry Yagi had hired, at the bottom of the pile Bakugo laid against the lorry panting in exhaustion as he tried to keep small explosions popping across his hands to keep his quirk cycling and preventing a build up of nitroglycerin in his blood which would literally make his heart explode.

"YEAHH!" Izuku cried out, finally glad to of finished the beach after ten months of effort with Bakugo.

"HOLY STINKING SUPER CRAP!" Yagi called when he arrived and saw the beach. "YOU TWO DID PLUS ULTRA!"

"SHUT IT!" Bakugo snapped. "I have been up since 6 fucking AM thanks to Deku here just to help finish the beach so just shut up. My fucking head is killing me."

"Still you have both done a good job." Yagi laughed as Izuku stumbled down the pile of trash, landing with a slight stumble at the bottom. "Which is why I have to say you are truely ready!"

"Finally." Izuku sighed with relief.

"So young Midoriya all I have to say is...EAT THIS!"

"THE FUCK?!"

"SAY WHAT?!"

END CHAPTER.

Thoughts?

Ideas?

Pairings you want to see?

Which Mech or Walker should he summon during the exams, go crazy with this if you like.

Also yes Bakugo isn't a total asshole by choice in this fic. Guy has to keep angry or he kicks the bucket, also yes Coffee is a weakness from a crack fic I read ages ago but instead of making Bakugo explode his own hair repeatedly I made it a "drinks too much and say hello coma" deal.
