Major spoiler warning: This article discusses deaths, defeats, and late-story outcomes from many manga and anime, including Jujutsu Kaisen, BLEACH, Demon Slayer, My Hero Academia, Hunter × Hunter, Toriko, Fullmetal Alchemist, and CLAYMORE.
“Strongest in the setting.” “On the hero’s side.” “Teacher.”
Put those three lines on one character sheet and you get someone with SSS combat power and apparently uninsurable life expectancy.
The original joke was simple: “Don’t like 90% of strongest characters die?” But that question mixes together two groups that distort the result. Strongest protagonists often survive because their overwhelming strength is the product. Strongest villains are often killed or sealed because defeating them is literally the victory condition.
The more interesting group is narrower:
non-protagonist, allied strongest or strongest-tier characters.
They do not always die. What happens instead is that stories tend to break the condition in which they can remain the strongest, stay beside the protagonist, and freely solve every crisis.
Death is only one collection method. There is also sealing, permanent injury, retirement, power loss, a humiliating defeat, being surpassed by the protagonist, being sent far away, or adopting a rule that prevents constant intervention.
For fun, this article calls that pressure the “Why Not Just Send Gojo?” tax. In more serious terms, it is pressure to dismantle the strongest-character position.
1. The real target is not the strongest character’s life; it is their function as a safety net
A friendly strongest character is difficult to write not merely because they are powerful, but because the audience can carry around a universal answer:
“Why not just call that person?”
An enemy appears. The protagonists struggle. The reader remembers there is a walking strategic nuke on the same side.
From that point on, the writer inherits an extra task every arc: explain why the strongest character cannot simply show up and fix the problem.
So stories attack access to the solution.
They can:
- kill the character,
- seal them,
- take away their powers,
- injure or retire them,
- let the protagonist surpass them,
- give them one decisive loss so they no longer feel invincible,
- station them in another region or battlefield,
- or give them a mentor’s rule such as “I will not fight my student’s battles for them.”
The rare condition is not “a strongest character who lives.”
The rare condition is:
a non-protagonist ally who stays alive, undefeated, fully powered, active, nearby, willing to intervene, and still unquestionably the strongest until the end.
2. Why does one overpowered ally create so much writing pressure?
They reduce uncertainty
Suspense research has long found that suspense weakens when success or failure feels completely certain.[1]
If the strongest ally can always arrive, the audience may know the answer before the conflict has developed.
The official Jujutsu Kaisen anime site describes Satoru Gojo as a teacher and a sorcerer acknowledged by himself and others as the strongest.[5] That is an excellent character hook. It is also, from the villains’ perspective, a giant sign saying: “Your first strategic objective is to remove this man from the board.”
They can consume the protagonist’s growth
Mentors are useful because they help a hero change. Research on heroic transformation discusses mentors as agents of growth and emphasizes movement from dependence toward autonomy, with transformed heroes later becoming mentors themselves.[3]
Translated into battle manga:
Teacher: “I’ll handle everything.”
cannot remain the final arrangement forever.
Eventually the story needs:
Teacher: “Now you handle it.”
Beating them is an instant advertisement for a new threat
Ten pages of a new villain saying “I am terrifying” is weaker than one panel of a known powerhouse failing.
Fans often call this the Worf Effect: a strong established character is defeated to demonstrate the level of a new threat. It is a fan/criticism term, not an academic one, but it describes the device well.
Gildarts being horribly overmatched by Acnologia, for example, tells the audience something extremely efficient: there are beings for whom “the guild’s strongest guy” is not an answer.
Death is an absurdly efficient multi-tool
Research on fictional character deaths finds that deaths of liked, moral characters are especially associated with meaningful, emotionally mixed responses rather than simple pleasure.[2] A study of 60 popular films also found death frequently linked to endings, growth, unity, and salvation.[4]
Kill a beloved powerhouse mentor and one event can:
- raise the villain’s threat level,
- remove the protagonist’s safety net,
- force independence,
- trigger generational succession,
- create grief and memory,
- transfer techniques, ideals, or unfinished goals.
From a plotting perspective, that is alarmingly cost-effective.
3. They do not have to die. You can kill only “being the strongest”
This is the key correction.
1) Physical removal: death or sealing
The cleanest answer. No more “why didn’t they come?”
2) Combat removal: power loss, injury, retirement
All Might is the textbook case. The official My Hero Academia site states that he exhausted his power fighting All For One and retired as a hero.[6]
The person remains. The emergency button does not.
Writer: “I didn’t kill him.”
Audience: “Great.”
Writer: “I did repossess the superpowers.”
3) Relative removal: let the protagonist surpass them
This is the peaceful solution.
Master Roshi can remain a revered teacher after Goku and Krillin become stronger than him. An official Dragon Ball article explicitly discusses the fact that they surpass Roshi while continuing to respect him as their master.[7]
Now the question “Why not call Roshi?” answers itself.
Keep the person. Transfer the job title “strongest” to the protagonist.
4) Reputation removal: give them a real loss
One clean loss can destroy the idea that this character is a guaranteed win condition.
A normal character can lose, train, and retry.
When “the strongest” loses, the ceiling of the entire setting moves.
Sometimes the loss comes bundled with a death certificate because the author wants to spend that rare black mark at maximum value.
5) Board removal: keep them strong but inaccessible
Hiko Seijuro is the elegant version: absurdly strong, but not a permanent party member.
Reborn uses another method: a mentor can be immensely capable while refusing to solve every battle for the student.
You do not need to destroy the power if you destroy access to the power.
4. The count only makes sense after excluding protagonists and villains
Counting “all strongest characters” creates two huge biases.
First, strongest protagonists such as Saitama or Mash are built around being overwhelmingly powerful. Their continued existence is part of the premise.
Second, strongest villains are often final bosses. Their death or sealing may tell us more about being the antagonist than about being the strongest.
So this 30-character audit uses a narrower operational definition:
- not the main protagonist,
- not a pure villain/final boss,
- allied with the protagonist,
- capable of functioning as a major safety net at that stage of the story,
- includes not only a single uncontested number one, but also organization-level strongest, mentor-level strongest, and obvious top-tier allies.
This is not a random sample of all manga. It is an exploratory audit of 30 famous battle-series examples selected because the “strongest ally” function is visible.
The percentages below describe these 30 examples, not the entire medium.
5. All 30 characters: what tax did they pay?
Legend:
- Loss = clear defeat, domination, or incapacitation
- Death = ultimately dies
- Nerf = permanent major weakening, retirement, or disability
- Away = strength preserved but intervention structurally limited
- Succession = strongest role/responsibility shifts to the next generation
- Escape = unusually clean survival
| # | Character | Series | Audit result | How the “strongest tax” was paid |
|---|---|---|---|---|
| 1 | Satoru Gojo | Jujutsu Kaisen | Loss / Death | Sealed, later defeated and killed in the battle of the strongest |
| 2 | Genryusai Yamamoto | BLEACH | Loss / Death | Bankai taken, defeated by Yhwach, dies; official site calls him the summit of all Soul Reapers[8] |
| 3 | Gyomei Himejima | Demon Slayer | Death / Succession | Fights as the strongest Hashira-tier pillar of the final battle and dies afterward |
| 4 | All Might | My Hero Academia | Nerf / Succession | Exhausts his power, retires, remains as a teacher[6] |
| 5 | Might Guy | Naruto | Loss / Nerf | Opens the final Gate, cannot finish Madara, survives with severe aftereffects |
| 6 | Isaac Netero | Hunter × Hunter | Loss / Death | Cannot defeat Meruem conventionally and turns his own death into part of the win condition |
| 7 | Ichiryu | Toriko | Loss / Death | Old-generation top power loses and dies, leaving the future to successors |
| 8 | Escanor | The Seven Deadly Sins | Death | Burns through his ultimate power and dies after the decisive fighting |
| 9 | Van Hohenheim | Fullmetal Alchemist | Death / Succession | Supports the final victory, then reaches the end of his remaining life |
| 10 | Lord Death | Soul Eater | Death / Succession | The old guardian’s era ends as Kid completes the new order |
| 11 | Teresa | CLAYMORE | Loss / Death | Official Shueisha material calls her the strongest warrior; she is killed by Priscilla[9] |
| 12 | Jiraiya | Naruto | Loss / Death / Succession | Dies against Pain after leaving critical knowledge to the next generation |
| 13 | Hiko Seijuro | Rurouni Kenshin | Away | Remains top-tier and alive, but is not a permanent emergency button in the hero’s party |
| 14 | Hayato Furinji | History’s Strongest Disciple Kenichi | Away | Keeps his “invincible superman” aura but is not allowed to solve the final conflict for everyone |
| 15 | Gildarts | FAIRY TAIL | Loss | Lives, but Acnologia brutally demonstrates that even this powerhouse can be overwhelmed |
| 16 | Benimaru Shinmon | Fire Force | Nerf / Succession | Officially “the strongest fire soldier”[10]; the ending changes the world’s entire power system |
| 17 | Wahlberg Baigan | MASHLE | Loss / Nerf | Loses to Innocent Zero; the strongest headmaster cannot remain the final solution |
| 18 | Reborn | Katekyo Hitman REBORN! | Away / Succession | Extremely strong mentor who does not simply fight all of his student’s battles |
| 19 | Arima Tsuchimikado | Twin Star Exorcists | Loss / Death | The strongest exorcist safety net is removed, passing the fight forward |
| 20 | Gen Narumi | Kaiju No. 8 | Relativized | Officially “Japan’s strongest anti-Kaiju combatant”[11]; survives, but the climax becomes a shared war rather than his solo answer |
| 21 | Matsuri Yagumo | PSYREN | Away | Powerful mentor whose ability to keep entering PSYREN is structurally limited |
| 22 | Zenjuro Saotome | Beelzebub | Escape | One of the cleanest cases in this set: top-tier ally, alive, without a giant permanent nerf |
| 23 | Genkai | Yu Yu Hakusho | Loss / Death→Return / Succession | Killed by Younger Toguro, later returns, but the combat throne has moved to the younger generation |
| 24 | Captain Bravo | Buso Renkin | Loss / Nerf | Defeated in conflict with the protagonist and later suffers serious damage |
| 25 | Shiro Fujimoto | Blue Exorcist | Death / Succession | A highest-rank exorcist dies protecting the protagonist and launches the story’s main conflict |
| 26 | Toki | Fist of the North Star | Loss / Death | Loses to Raoh and later dies, leaving the path to Kenshiro |
| 27 | Avan | Dragon Quest: The Adventure of Dai | Loss / Fake death / Succession | Sacrifices himself against Hadlar, is believed dead, later returns, while the role of ultimate hero has already moved to Dai |
| 28 | Bulat | Akame ga Kill! | Death / Succession | Wins his immediate battle but dies from lethal poison, leaving his weapon and role to a junior |
| 29 | Sieghart | RAVE | Death | Powerful ally exits through self-sacrifice |
| 30 | Bang | One-Punch Man | Loss / Nerf / Succession | His conflict with Garou destroys the idea of him as an automatic answer; he later retires as a hero |
In this particular set, 15 of 30 ultimately die: exactly 50%.
But the more revealing number is not the death count.
Among the survivors are people who lose powers, retire, suffer permanent injury, take a decisive defeat, become structurally unavailable, or hand the combat throne to the next generation.
Under a broad definition of “no longer able to stay the strongest and freely solve the protagonist’s problems,” roughly 28–29 of these 30 show some kind of dismantling, depending on borderline classifications.
That is not a claim that “96% of all manga strongest allies get dismantled.” This sample was selected specifically for visible strongest-character roles.
The useful observation is the pattern: survival frequently comes with removal, relativization, or restriction.
6. Strong characters who survive tend to use the same escape routes
Get surpassed by the protagonist
The Master Roshi route.
The mentor keeps dignity and narrative value, while losing the ability to invalidate every future fight.
Stay powerful but stay away
The Hiko Seijuro route.
“World-class monster, currently on a mountain” is surprisingly good narrative fireproofing.
Refuse to fight the student’s battles
The Reborn route.
The limiter is not physical; it is educational policy.
Lose once, properly
The Gildarts route.
Once the audience has seen “even he can lose,” the author no longer needs to kill him to create uncertainty.
Retire
The All Might/Bang route.
Keep the character. Remove the name from the answer sheet for combat problems.
The common logic is simple: the story wants to cancel the strongest character’s monopoly on problem solving.
7. Why does the strongest character’s first real loss so often look terminal?
Being undefeated is part of the brand.
That makes ordinary losses hard to spend casually.
If an author finally gives “the strongest” a black mark, the temptation is to make that one loss do everything:
- certify the new villain,
- raise the setting’s ceiling,
- remove the hero’s safety net,
- start a new era,
- force succession.
So we get a recurring career path:
win → win → win → first truly serious loss → death.
A normal character loses and gets a training arc.
The strongest character loses and gets paperwork from the afterlife.
Because the loss is rare, it is often written as a maximal-impact event.
8. If you reincarnate as the strongest allied teacher, how do you survive?
Now we can build an isekai survival manual.
You open your new character profile:
“Strongest in the world.”
“Teacher of the protagonist.”
“Deeply cares for students.”
“In the final battle, willing to sacrifice—”
Stop reading. Run.
But there is a smarter strategy than international escape.
Move 1: Lose early — to the protagonist
Pick the protagonist.
Do not deliberately lose to the new final boss.
If the writer is currently looking for someone impressive to murder so the new villain looks terrifying, you have just volunteered as a demonstration model.
Move 2: Publicly surrender the throne
Say: “You have surpassed me.”
You just delivered protagonist growth and generational succession in one scene.
Move 3: If necessary, pay the dignity tax too
A dramatic bow or apology can help destroy the untouchable aura, but humiliation alone is not enough.
If you bow today and one-shot every villain tomorrow, the audience will immediately ask why you are not solving everything again.
The true objective is to surrender the problem-solving monopoly.
Move 4: Retire into an adviser role
Move from combat department to education department.
You can remain popular, useful, and alive without having to die just to pass on your will.
Move 5: Put “I don’t fight my students’ battles” in your employment contract
Now the writer does not need a new overseas business trip every arc.
Reincarnated me: “Apparently I’m the strongest. I would like a sparring match with the protagonist immediately.”
Protagonist: “Teacher, why?”
Me: “Come at me seriously.”
Thirty minutes later:
Me: “Guh… magnificent. From today on, you are the strongest.”
Writer:
“THANK YOU FOR PROCESSING THE PAPERWORK EARLY.”
Pay the strongest tax voluntarily in chapter 3, and maybe you can avoid the scheduled death event in chapter 72.
9. The real death flag is not “strongest.” It is “active, allied, nearby, and willing to intervene”
Being strongest alone is survivable.
The danger comes from stacking conditions:
- not the protagonist,
- allied with the protagonist,
- overwhelmingly stronger than the protagonist,
- still active,
- physically close enough to help,
- emotionally willing to help,
- recognized by the enemy as the greatest obstacle,
- not yet surpassed by the next generation.
Every additional condition increases the writer’s obligation to explain why this character does not solve the current arc.
So a more interesting metric than survival rate is the untouched-throne retention rate:
alive,
undefeated,
fully powered,
not retired,
not isolated,
not surpassed,
still nearby and free to intervene.
A non-protagonist ally who satisfies all of those until the end is genuinely rare.
The story does not need to kill them.
It only needs to kill their status as the answer to everything.
10. Conclusion: the strongest character’s real enemy was the script
The question began as “Do 90% of strongest characters die?”
No. In this exploratory 30-character set, final deaths are 15/30 — half.
But after changing the question, the pattern becomes much stronger:
non-protagonist allied powerhouses often survive only after losing a battle, powers, active status, accessibility, or the throne itself.
The reason is brutally simple.
Protagonist: “This enemy is too strong!”
Reader: “Why not call the teacher?”
Writer: “That is exactly the problem.”
The strongest character’s ultimate weakness is not elemental affinity or a cursed technique.
It is that their mere existence can create a script bug called:
“Why not just send this person?”
So if you reincarnate as the strongest teacher, do not look for the final boss first.
Find the protagonist.
Lose once.
Return the throne.
Bow if necessary.
Then announce:
“I am an adviser now.”
Strongest-character tax: paid in full.
