Powerstack

Quirk

Quirk Name: Powerstack

Quirk Type: Emitter

Quirk Overview:  Powerstack is a quirk that allows the user to stack or stockpile stored power multiplicivally. The user can do so in the form of single attacks, or in spreading it throughout their whole body to empower themselves(a multiplicative factor of “everything”, such as Durability, etc.), raising their destructive, defensive, and speed capabilities. This can result in them at several times their normal capabilities, if not more through mastery. The quirk manifests visually in the form of a reddish, almost fiery aura or glow.

Quirk Limits/Drawbacks, strengths, and weaknesses:  The quirk is one that requires mastery over time and sometimes, patience. It relies on the user’s base physical strength as a foundation for what it increases by and how it increases. As the person uses Powerstack, they will notice that their body will begin to encounter strain and pain on an exponential level similar to the increase in strength, feeling like their body is being burned away in exchange for power. It also requires focus as if the user is pressured too much, strains too much, or is attacked and cannot maintain, they will lose the built up power or may fall out of the empowered state.

Quirk overuse/cooldowns:  Overuse can induce bleeding, muscle strain and damage, as well as broken bones. While the quirk can help the user to push through pain and manage through say, having a broken arm,when the dust settles, that arm is still broken and the user will succumb to the strain of the quirk.

Quirk Stats(Used as a general metric and scale of power and is not fine-tuned accurate nor absolute fact):  out of 10, 5/10 being average.

Future Development: Currently Jouta can barely use it, in fact he isn’t even fully sure if he has a quirk or not despite the medical diagnosis confirming he has a quirk factor. Over time he will likely develop and grow, but in order to gain all of the capabilities his quirk can get, that potential will be realized through tribulation, training, and suffering in order to reach those points. By the time he graduates he could utilize x10 if not x15, and only part of the way into being a pro hero will he push to the absolute pinnacle that is x20.

As of the Sports Festival(11/7/25) he mastered Times Two, able to seamlessly use it without major strain or injury until it’s used for a long time(an hour.)

‘Times One’(really times 1.5) is something he can use for hours on hours at a time until the strain and downsides set in.

---

As of the Hero Internships third day(2/3/26) Jouta has Mastered Times Three, able to seamlessly use it for 30 minutes until major strain or injury sets in.

---

As of over the irp summer(summer 2026) Jouta is proficient with Times Four and able to use it for 5 minutes, strain starting to set in at 2.5 minutes. He can use Times Five but only for a minute and a half, strain setting in at  60 seconds, meaning he’s only got the basics of Times Five.

Pre sports fest: Jouta has become better with x5, and managed to unlock x6 during his pre-sports fest training. Strain sets in at a minute still, but he can use times 5 for five minutes before thing it breaks him down. Times six sets in strain at 30 seconds, and can be used for a minute's time. Times Seven, he can use for only a brief moment and can put himself out of commission if he uses too hard of an attack with it.

Post sports fest: Jouta has spent the last month locking himself within the gym's backroom for six hours a day, working to overhaul how he fights and uses his quirk, creating not only a split in his fighting style, but the creation of that whole new side: the High Caliber style. He's also now able to briefly focus Powerstack more in one or several distinct areas of his body than in others, with the disadvantage that it puts more strain on that part briefly and lessens the extent that Powerstack empowers the rest of him comparable to how much he's focusing into the given part.

Jouta spent the last month of December training within the gym’s backroom for 12 hours a day. He’s managed to get a good grasp on how to focus Powerstack in the form of ‘pressure’ into different areas of his body. He’s also fully formed the High Caliber and Low Caliber styles, though the High Caliber style could still be refined with further training, and practical fights using it. He’s also proficient in using Times Six, and can just barely use Times Seven. Jouta’s  awakened his quirk after two months of intense and determined training, using  his quirk in new ways he hadn’t thought of before, and pushing his limits in every way he could with the deep need to be more than just a similar fighter to Platinum, stuck in his shadow, striving to be seen as himself.. And not a weaker.. Somewhat different Platinum.

QUIRK AWAKENING:

After near two months straight of extreme and in depth training that pushed the limits of not only how hard he could use his quirk, but in what ways he could use his quirk, what new ways he could use what he already had with it(like the pressure spreading) and through the fleshing out of low caliber style, and the creation and refining of high caliber style, Jouta has awakened his quirk. He gains the following two awakening abilities:

POWERSTACK DIVISION: This allows Jouta to enter Powerstack, using a higher level but dividing it down. The result is a weaker level of Powerstack, but it has less strain factor than if he were to enter that level normally.

The formula for it is:    num 1 / num 2 = num 3 power

strain = num 3 power - lowest between num 1  and num 2

This in practice means he could power into Times Six, for example, divide it down to Times Three by a factor of two, but the strain of it would be that of Times “One”(1.5x) as with the formula, 6/2 = 3 - 2 = 1, thus the strain of it is that of times one. You might wonder why someone would bother with this because it seems like it makes them weaker, but the real advantage of it is  stability, consistency, and attrition. With it, Jouta could use levels he’s already good with even better and last longer with them, meaning sustained fights would be less of a problem for him to deal with, as well as the fact that he’s being injured less by his quirk, meaning successful attacks from a foe wouldn’t worsen it as much as it would normally.

POWERSTACK MULTIPLICATION: This allows Jouta to enter Powerstack, using a lower level but multiplying it up. The result is a stronger level of powerstack, but at much higher strain than if he were able to enter it normally.

The formula for it is:   num 1 X num 2 = num 3 power

strain = num 3 power + the lowest between num 1  and num 2

This in practice means he could power into Times Four, multiply it up by to Times Eight by a factor of 2, but the strain of it would be that of Times Ten. You might wonder why someone would bother with it as it seems like the extra boost it gives isn’t worth all of the extra strain, but the real advantage of it is shock-exposing him to higher levels so that the first time real use doesn’t put him down for the count, and works for brief, single attacks. With it, Jouta could massively empower a single punch or super move, but he’d have to make that count as it would no doubt end up being his last attack in a fight in most cases.
