Summary
My Hero Academia’spower system is quite complex, with quirks divided into multiple categories based on their workings. The primary categories that define quirks are Emitter type, Mutant type, and Transformation type. However, a few other subsets of quirk categories also exist that are populated by quirks that blur the line betweenthe three primary quirk categories. Accumulation type quirks are one such quirk category that fails to fit into conventional quirk categories.
With less than ten quirks in the entirety ofMy Hero Academia, accumulation type quirks are some of the most rare powers in the series. Despite their rarity, these quirks have been deemed to be some of the strongest in the series. Consequently, these powers are quite complex and have intricate systems that define the overall power. With One For All also being an accumulation type power, it’s safe to say that these quirks hold considerable significance inMy Hero Academia.
What are Accumulation Type Quirks?
Quirks Relying On Stockpiled Energy
As a subset of the three primary quirk categories, Accumulation-type quirks are few and far between inMy Hero Academia. While these quirks can fit into any of the three primary quirk categories — Emitter-type, Transformation-type,and Mutant-type quirks— their effect still remains the same. These quirks are defined by their stockpiling effect, meaning these powers require the user to store energy first in order to be able to make use of the quirk. This energy could be in the form of physical mass, kinetic energy, or even stress, all of which are expended by the user when the quirk is activated.
However, even within the Accumulation-type quirk category, each quirk has a slightly different working. For instance, Stress relies on the buildup of the user’s negative emotions, which are then utilized in the form of physical enhancements. On the other hand,Fa Jin relies on a user’s physical movementsand stores up the kinetic energy that is derived from those actions. This diversity of powers makes Accumulation-type quirks quite vast, though the primary stockpiling effect remains the same.
Variations of Accumulation Type Quirks
Accumulation Type Quirks Utilize Different Forms of Energy
Similar to its counterparts, Accumulation-type quirks come in all shapes and forms. This has led to a few different types of Accumulation-type quirks coming about, with each one working on a slightly different principle.Deku’s One For Allis one of the most widely recognized Accumulation type quirks, yet it also works on the most novel principles out of the bunch. Instead of relying on the action’s users to generate energy, One For All accumulates power over time while remaining within the user.
Moreover, this isn’t the only method of accumulating power for One For All, as each time the quirk is passed on to a new user, One for All strengthens in power considerably. As more quirks are added within One for All, its stockpile increases, and the quirk becomes all the more powerful. One for All’s accumulation has reached such a limit that a new user cannot withstand its power unless their body is physically strong enough.
An unprepared body cannot inherit One For All fully.
Different Iterations of Accumulation
While One For All’s method of accumulation might be rather extreme, there are other less intense examples, such asFat Gum’s Fat Absorption quirk. The quirk relies on external energy that is converted into body fat, and once enough energy is absorbed into Fat Gum’s body, he can then use this accumulated power to strengthen his own attacks or boost his own defense. Stress and shame are two more Accumulation type quirks that work on a slightly different principle from their counterparts. Instead of building energy over time or relying on an external source, these two quirks are fueled by negative emotions of a person.
In the case of stress, negative emotions such as stress, anger, or anxiety can power the quirk. Shame, on the other hand, relies on embarrassment to fuel the quirk’s power. These two powers also differ in the sense that the quirks do not consume the energy accumulated over time, which is the case for bothEri’s Rewind qurikand Fat Gums Fat Absorption. This showcases that even within the subset of Accumulation type quirks, each quirk differs considerably in its functions and workings.
Drawbacks of Accumulation Type Quirks
These Quirks Are Limited By Their Need for Stored Energy
Compared to the other quirk categories, Accumulation type quirks are laced with drawbacks and limitations, some that can even be lethal for heroes in the line of fire. One For all might be an exception to this, as the user has continuous access to the quirk’s power. However, other Accumulation type quirks are vulnerable to their energy depleting during battle. Fat Gum’s Fat Absorption is a prime example, asFat Gum would be left vulnerableif his fat reserves are depleted entirely.
If it’s a quirk where you accumulate something and change it into energy, I can’t copy what needs to be accumulated.
Eri’s Quirk is also limited due to its energy requirements, as her horn goes back to normal right after every usage, meaning her Quirk can only be used once before all of its energy is depleted. This was also witnessed during the timeMonoma copied Eri’s quirk. While he was able to acquire the signature horn of Eri’s Rewind Quirk on his head, he was unable to use its power since it required a buildup of energy over time. The same was witnessed when Monoma tried to copy Midoriya’s One for All, as he failed to use the power since there was no buildup or stockpiling effect in his version of One for All.
Fa Jin is also rather limited without any previous kinetic energy stored, as each usage of the quirk requires the user to generate kinetic energy beforehand. Without ample preparation, Fa Jin can be rather weak in combat. These weaknesses indicate that Accumulation type Quirks are rather weak compared to their counterparts, albeit One for All is an exception. Still, it’s worth considering that during the time One For All was in the hands of its original user, the quirk had little to no power. It was only after it was passed down through generations and acquired several other Quirks thatOne For All became a powerthat could rival All for One.
Strongest Accumulation Type Quirks in My Hero Academia
One For All Stands As the Strongest Accumulation Type Power
The Accumulation type quirks witnessed inMy Hero Academiahave been arguably thestrongest powers in the entirety of the series, whether it’s their utility or outright brute strength. Each Accumulation type quirk has its own unique strengths that are clearly leagues above the rest. However, in terms of the strongest Accumulation type quirk, One for All clearly takes the cake, as no other quirk can rival its unmatched prowess. With seven different quirks accumulated within it and power stockpiled over seven generations, One for All is an unbeatable quirk that none could ever hope to rival.
In terms of utility, however, Eri’s Rewind is a close second, as this quirk has the ability to rewind almost anything, whether it’s bringing back a person in their youthful form, or deleting an enemy from existence altogether. However,Eri’s Rewind quirk is severely limitedby its energy requirements, as it takes a considerable time for her to build up the energy required to use the quirk. Fa Jin in the hands of Deku also proved to be a powerhouse, as he was able to use the quirk in conjunction with his other quirks to bring out the best of his power. Still, it pales in comparison to the utility and strength offered by other Accumulation type quirks.
