Though anime covers a breadth of genres, many of the most popular series are action-packed and include some of the most creative, and recognizable, power systems in fiction. Power systems are not unique to anime, but few mediums host such a diverse range of abilities and skills. Whether complex or simple, they all do one thing in common; create high-octane action.
But what makes a power system good? The best systems are clearly defined and have limits - even if those limits are eventually broken. Additionally, the powers must serve and enhance the narrative and characters of the anime, otherwise, it becomes just a spectacle with no meaning. So, what are the best power systems in anime?
Ki: 'Dragon Ball'
In the West, the Dragon Ball series is one of the most beloved anime series of all time. It also has some of the most recognizable names in anime - and not just character names. The Kamehame Wave is, undoubtedly, one of the most iconic attacks in the medium, and there isn't a fan out there who hasn't tried to unleash this ability.
The Kamehama, like many other abilities in the series, is powered by a warrior's internal Ki energy. Ki is a finite resource, but those that have mastered it are capable of incredible feats of destructive power; not to mention other abilities, like flight. Engaging in its simplicity and accessibility, Ki is among the best.
Chakra: 'Naruto'
Like Ki, Naruto's Chakra system is based on one's limited internal energy. However, Chakra adds levels of complexity, while remaining accessible, which creates a more dynamic system. Shinobi train to unlock and wield their internal energy to fuel Jutsu (skills), which can take on many forms; especially when elemental affinities are taken into account.
Even though Chakra can be used in so many ways, the feats of characters make sense; even when the action begins reaching into over-the-top territory (looking at you, Kaguya). Chakra is iconic and one of the best power systems in anime. Believe it!
Breathing Styles: Demon Slayer Kimetsu no Yaiba
Demon Slayer may be one of the newest kids on the block, but it has made waves in the fandom. Excellent character work, stunning animation, thrilling sound design, and an engaging narrative have all aided in the success of this series. The titular Demon Slayers employ various Breathing Styles to empower their swordsmanship, allowing mere humans to stand toe-to-toe against powerful demons.
While all the Styles began with Sun Breathing, they diversified over the life of the Demon Slayer Corp. Each Style has unique advantages and disadvantages - whether it is extreme speed, power, or adaptability. However, they all share the ability to enhance the user's durability, stamina, and reflexes. To be the best, one must master their breathing.
Magic Grimoires: 'Black Clover'
Black Clover is a mixed bag in terms of storytelling and quality which, unfortunately, often overshadows its power system. There are a lot of anime that use magic spells, but Black Clover puts a few unique twists on it. First, the use of Grimoires (spellbooks) provides a clear indicator of the progress through the acquisition of new spells but also creates a limitation in the number of spells a person can attain. Also, the fact that different social classes are based on how much mana a person has is an excellent worldbuilding feature.
While everyone in the world has magic, they are attuned to a certain element. However, through training and determination, individuals can create personalized subcategories, making every powerful friend and foe unique wizards. Pushing past its limits, Black Clover's magic system is more than it seems.
Haki: One Piece
Dormant in all living things, Haki is a spiritual power that, theoretically, can be achieved by any creature in One Piece. There are three varieties of Haki; Color of Arms, Color of Observation, and Color of the Supreme King. Color of Arms allows the user to coat themselves in a layer of protective spiritual energy which boosts both their defensive and offensive capabilities. The Color of Observation enhances the perception and even lets skilled users look into the near future. Lastly, there are a few, special individuals who can use the Color of the Supreme King to overwhelm the willpower of people around them.
After the formal introduction of Haki, One Piece entered a new era. Haki is powerful and, when combined with Devil Fruits, has created many interesting fights. It may not be supreme, but Haki is a king among power systems.
Quirks: My Hero Academia
While most of the abilities seen in My Hero Academia hardly meet the dictionary definition of 'quirk,' the power system has quickly become iconic within the anime fandom. From the superhuman to the supernatural, the Quirk system is filled with clever and unique abilities. These powers have combined to create some of the most impressive fight scenes in recent years.
Like many anime power systems, there is a focus on growth and breaking characters' perceived limits. This is exemplified in the main character Deku's ability One For All. It is only as powerful as it is because it was passed down through generations of users, each adding to its overall potential. My Hero Academia's Quirks are truly Plus Ultra.
Alchemy: Fullmetal Alchemist: Brotherhood
To gain something, something else of equal value must be lost. This is Fullmetal Alchemist's Law of Equivalent Exchange, and it is one of the primary driving forces behind the entire series and its power system; alchemy. At first glance, alchemy looks like another simple magic system. However, it is based on science and an understanding of the fundamentals of reality. It is also limited by the need for transmutation circles to enact the alchemical process.
Power is unlocked through education and study; there are no shortcuts in alchemy. Even those that have seen the Truth, removing their need for a circle, are still bound by their knowledge. It doesn't take a genius, though, to acknowledge the greatness of alchemy.
Devil Fruits: One Piece
Iconic. Powerful. Silly. The Devil Fruits of One Piece are one of the most creative power systems out there. Unlike most power systems, Devil Fruits are extrinsic and are not tied to a person's personality, spirituality, or any other internal motivations. All that is needed to gain power is to eat a weird-looking fruit.
The wide range of abilities Devil Fruits bestow allow for some truly unique action and fights. With enough creativity and training, any fruit can be useful. The major drawback, though, is that Devil Fruit Eaters lose the ability to swim, which, in a world of islands and oceans, is a bit of a problem. One Piece's Devil Fruits drown the competition.
Stands: Jojo's Bizarre Adventure
After the original power system (Hamon) of Jojo's Bizarre Adventure outlived its relevance to the narrative - though, not before creating some truly memorable fights - the Stand system was born. A manifestation of an individual's spirit, Stands are as unique as those who wield them. Thanks to the incredible variety of abilities that Stands have, every fight is unique and memorable. Brute strength isn't enough - it takes wits to overcome an enemy Stand.
Despite the diversity, Stands still have rules. Each one has a limited range, damage sustained by the Stand is sustained by the Stand User, and non-Stand Users cannot see Stands (though they can still be affected by them). Jojo's power system Stands above the rest.
Nen: Hunter x Hunter
Another spiritual power system, Nen from Hunter x Hunter is one of the most well-developed systems in fiction. It is robust and complicated, but developing an understanding of Nen alongside the characters is a rewarding experience. After its introduction, Nen becomes a staple of the series, and the creative uses of the power are engaging and fun to try and dissect. Each new encounter is like a puzzle for the viewer.
Because it is so well-developed, every increase in power or new ability makes complete sense within the rules of the world. Nen is unsurpassed in its creativity and detail, as well as its impact on both the characters and narrative of Hunter x Hunter.
