I'm gonna subscribe to the idea that Class A becomes the ultimate hero team once they graduate so I'm curious about any other headcanons you have for that
Yep, I’m all here for that. I personally headcanon that Class 1-A will continue to work together once they graduate and become real heroes.
From what I’ve gathered, only a few heroes work in groups, or only when it’s necessary because the situation is not manageable alone (such as when the heroes went to save Bakugou). But Class 1-A has experienced so much together and become such a good team, knowing their strengths and weaknesses by heart, it just makes sense for them to keep working together. Due to that, they kind of start a new era for heroes – where heroes work together instead of alone.
I came up with a few ideas for that:
There are some of them who start their own hero-company or hero-office, such as Bakugou – who wants to become the best without help – and probably people like Todoroki and Tokoyami, since they’re just used to being alone. Despite that, they still show up together with their former classmates at the job. Bakugou claims it’s a coincidence, but Kirishima reminds him happily that Blasty rushed over as soon as he called him for help. (Bakugou tries to explodo-kill him for that, but Kirishima’s quirk prevents any harm.
Some of the children start hero-companies together, though, and specialize in different fields. For example, Sero, Mina and Satou become famous for capturing villains without much of a fight (though Satou with his strength can easily engage in a fist-combat if needed) and Jirou, Kaminari, Shouj and Tooru are pros when it comes to wiretapping and shadowing suspects.
Still, even though they may specialize in one field doesn’t mean they’re not able or ready to take on different jobs. Especially if they know that their other friends will be there, too.
Some of them, like Todoroki and Tokoyami, still hesitate when it comes to working together, since they fear that they will accidentally hurt their friends with their quirks should they lose control. So to “heal” them from that, the rest of Class 1-A comes up with a plan – for Todoroki, they have their hero-outfits made fireproof and have an alloy put onto their shoes so that their feet can’t be frozen to the ground. For Tokoyami, they start carrying signal rockets around, assuring him that they would use it to weaken his shadow should he go on a rampage.
They all know that this would not be enough to protect them completely from harm, but it’s the thought that counts and puts Todoroki’s and Tokoyami’s mind at ease, and the two are grateful for that.
Whenever the children group up and do work together, Bakugou and Izuku somehow become the unspoken leaders of the whole thing. They are the ones to figure out their battle strategy, as well as the most powerful fighters next to Todoroki (but Todoroki is more than happy to give them the leader role, since he is not comfortable with leading). They are also the most determined and spirited ones, and their fire is what propels the rest of the class forwards to go beyond their limits.
Their strategies are on-point and close to never fail, and even if they do, there is always a Plan B or even Plan C, which surprises and catches more than one top villain off-guard.
Their hero-outfits is a very important part of how they work and how they work together, so the outfits are constantly changing as they try to accommodate them to their needs. To ensure that they don’t forget anything important, Class 1-A work close together, discussing possibilities and getting suggestions from their friends.
It’s Mei Hatsume who designs and produces the outfits they want for them. Her company is booming because of their orders and the publicity she gets due to the newest top heroes wearing outfits she made for them.
The sign-language (look here for that) becomes a thing between the children, making the teamwork even easier because they can communicate without being understood by their opponents. Since the signing only work when they can see each other, though, they ask Mei to design them some sort of headsets, little things that sit in their ears invisible for the opponents, and can’t be wiretapped.
Sometimes the children simultaneously mute their headsets for a moment when Bakugou starts swearing very loudly, or when Kaminari is using his electricity and makes the whole line buzz with static.
Believe it or not, but their jobs go over without much collateral damage, even though one would think that when there are quirks like Bakugou’s, Izuku’s or Todoroki’s involved. Experience, training and (Aizawa’s) education has taught them to minimize the damage.
Sometimes, though, some villain makes a grievous mistake. Like seriously hurting one of them, or insulting one of their teachers and friends. Then it can happen that there is some serious collateral damage and a very damaged villain (who regrets some life-choices) involved.
Some quotes are very often used and, at one point, get highly associated with the former Class 1-A. For example “Don’t worry, we are here” (Izuku’s catchphrase when he is alone is “Don’t worry, it’s going to be alright) or “It’s a logical ruse”. Also very common among them is “Go beyond – Plus Ultra!”
Even though they graduated, Class 1-A stays in very close contact with U.A and, especially, with Toshinori and Aizawa. Visiting them is a common and weekly event – of course, Izuku visits Toshinori almost daily – and they even call their former teachers as often as they can when they are not able to visit them in person. Toshinori is delighted by all of that, loves to have the children so close. Aizawa is just as happy, even though he is not that good at showing it. But the children know how to read his moods a long time ago.
The children even go as far as make the homes of their teachers burglar-proof, installing alarms that inform them should some idiot of a villain try to get near either of them.
Aizawa and Toshinori know about it, but just (fondly) shake their heads and say nothing about it.
That’s all I got for the moment, and I came up with this in the spur of the moment. I hope there are some ideas in there that you will like. =D
