Most fans can name All Might in a heartbeat, yet the details behind his power are easy to mix up. Start with the anchor fact: All Might is the eighth holder of One For All, according to Wikipedia (encyclopedia character list), and the rest of the profile splits into what the series confirms and what still needs checking against the chapters.

What is All Might’s real name?
All Might’s real name is Toshinori Yagi, and that identity sits under the hero persona that made him famous.
Real name and hero identity
- Real name: Toshinori Yagi, per Anime Characters Database (character profile site)
- The kanji in the name reportedly mean “eight” and “tree”, according to Heroes Wiki (fan-run wiki)
Eighth holder of One For All
- All Might is the eighth holder of One For All, per Wikipedia (encyclopedia character list)
- One For All accumulates power and transfers it across generations, according to Anime Characters Database (character profile site)
Title as Symbol of Peace
- He was the No. 1 Pro Hero and is known as the Symbol of Peace, per Anime Characters Database (character profile site)
- English voice actor Christopher Sabat and Japanese anime voice actor Kenta Miyake are both credited, per Wikipedia (encyclopedia character list)
The implication: The name question is settled, so the harder questions sit in the plot, not on the identity card.
Is Deku’s dad All Might?
No. All Might is Izuku Midoriya’s mentor and official successor, and the two are not blood relatives, according to AniCodex (anime character guide).
Izuku Midoriya’s biological father
- Izuku is All Might’s official successor and not related to him by blood, per Anime Characters Database (character profile site)
- No supplied source names Izuku’s biological father
Mentor relationship between All Might and Izuku Midoriya
- After his rematch, All Might dedicated himself to training Izuku and became a teacher at U.A. High School, per Wikipedia (encyclopedia character list)
- Nighteye disapproved of Izuku being chosen and had trained Mirio Togata as an alternative candidate, per Wikipedia (encyclopedia character list)
Was Deku’s dad ever revealed?
- The supplied evidence does not identify Izuku’s biological father
- Check the chapter text before publishing any claim about his appearance
Fans search for a family link because the mentor bond looks like one. The sources show no blood tie, so the weight of the relationship rests on training and trust, as AniCodex (anime character guide) frames it.
The catch: Readers hunting for a father figure will find a mentor, and no supplied source supports anything beyond that.
Did Deku get All Might power?
Yes. All Might passed One For All to Izuku Midoriya after picking him when Izuku ran in to save Katsuki Bakugo from a villain, according to Anime News Network (anime news outlet).
Passing of One For All to Izuku Midoriya
- All Might transferred the power by giving Izuku a strand of his hair to eat, according to My Hero Academia Wiki (fan-run wiki)
- Izuku is described as the ninth and final wielder, per the same wiki, which also notes that successor numbering varies across sources
- One For All can move willingly through DNA or be taken by force, with a telepathic link between holders, per My Hero Academia Wiki (fan-run wiki)
Two holders, one Quirk, and one pattern: the lineage is well-sourced, while Izuku’s control level rests on a single low-confidence outlet.
| Trait | All Might | Izuku Midoriya |
|---|---|---|
| Holder order | Eighth (Wikipedia (encyclopedia character list)) | Ninth (My Hero Academia Wiki (fan-run wiki)) |
| Starting state | Born Quirkless, per Heroes Wiki (fan-run wiki) | Quirkless at start, per My Hero Academia Wiki (fan-run wiki) |
| Control of the power | Stockpiled strength, wielded for approximately 40 years, according to Heroes Wiki (fan-run wiki) | Rudimentary at first and damaging to his body, reportedly closing on All Might’s level by series end, per GameRant (gaming and anime news site) |
Nana Shimura as the previous holder before All Might
- Nana Shimura was the seventh holder, and she passed the Quirk to Toshinori before All For One killed her, per Anime News Network (anime news outlet)
- She appointed All Might as her successor, according to CBR (pop culture news site)
The implication: The power transfer is the best-supported part of the story, but the ordinal labels still need a footnote before anyone repeats them.
Readers who see “ninth holder” in one place and “successor” in another are looking at the same chain, so the chain itself should come first.
Who finally kills all for one?
All Might is the name the sources give, though they describe him defeating All For One rather than a verified final blow. According to CBR (pop culture news site), he won the final battle using the last of One For All.
All Might vs All for One
- All Might was severely injured in his first fight with All For One, which limited his use of One For All, per Wikipedia (encyclopedia character list)
- After winning the rematch, he lost the ability to use One For All, per Wikipedia (encyclopedia character list)
Final confrontation with All for One
- The technique named in the final battle is “United States of Smash,” per CBR (pop culture news site)
- All Might retired as a pro hero after exhausting One For All, per Anime Characters Database (character profile site)
- Whether he lands the final blow, or another character does, is not settled in the supplied evidence
Defeat and kill are different claims. The sources support the defeat, so any headline saying someone “killed” All For One needs chapter-level proof, as CBR (pop culture news site) does not provide.
The catch: The answer hinges on one word, defeated versus killed, and the sources only settle the first.
How big is All Might?
Size is the weakest-sourced part of the profile, and the numbers that circulate come from outlets with thin editorial backing.
Build before and after injury
- His injury in the first fight with All For One left him unable to use One For All for long, per Wikipedia (encyclopedia character list)
- His limited usage time is a key limitation, and he could use the power only for short periods after the injury, according to Wotpack (character data site)
- No supplied source confirms the name “Skinny form” for his thinner post-injury appearance
All Might height and age
- Height is reported at 220 cm, according to BritainDaily.uk (UK blog)
- Birthday is June 10 and age is approximately 54 to 56, according to Wotpack (character data site), a low-confidence figure
The 220 cm figure comes from one UK blog, and no official profile in the supplied evidence confirms it, as BritainDaily.uk (UK blog) is the only source for it. Anyone quoting a height should label it provisional until an official profile backs it.
All Might death in the story
- The supplied sources do not confirm whether his death is depicted in the story
- Readers should check the final chapters before repeating any claim about it
The implication: Physical details are the least certain part of the profile, so treat any number as a working estimate.
Timeline of One For All
- Before All Might’s career (no exact date): Nana Shimura holds One For All and passes it to All Might, according to Anime News Network (anime news outlet)
- Date not given: All Might is injured in his first fight with All For One, per Wikipedia (encyclopedia character list)
- Start of the series: All Might selects Izuku after he runs in to save Katsuki Bakugo, per Anime News Network (anime news outlet)
- After selecting Izuku: All Might becomes a U.A. High School teacher to train his successor, per My Hero Academia Wiki (fan-run wiki)
- Late series: All Might defeats All For One with the last of One For All and retires, according to CBR (pop culture news site)
The implication: The order of events holds up, but the sources give no exact dates, so keep the timeline in sequence rather than adding calendar years.
Confirmed facts vs. what’s unclear
Confirmed facts
- Real name is Toshinori Yagi (Anime Characters Database (character profile site))
- Eighth holder of One For All (Wikipedia (encyclopedia character list))
- Nana Shimura passed the Quirk to All Might before All For One killed her (Anime News Network (anime news outlet))
What’s unclear
- Which character delivers the final blow to All For One; the CBR account names All Might, but chapter text is not cited (CBR (pop culture news site))
- Whether All Might’s death is shown in the story
- Whether All Might has a romantic partner; no source was supplied
- Exact height and age; the figures rest on BritainDaily.uk (UK blog) and a low-confidence age range from Wotpack (character data site)
- Reportedly not Izuku Midoriya’s blood relative, per AniCodex (anime character guide)
- GameRant’s claim that Deku’s real name is “Zen Shigaraki” conflicts with every other supplied source (GameRant (gaming and anime news site))
The implication: The open list is longer than the confirmed list, which is the honest state of this evidence base.
In All Might’s own words
One line from All Might carries the symbol-of-peace idea that runs through the series.
“I wanna make a world where everyone smiles and lives together happily. For that to happen, people need a symbol… A symbol of peace!”
All Might, quoted by Anime News Network (anime news outlet)
The same feature records his farewell to the Quirk in a single line, a goodbye to One For All, as quoted by Anime News Network (anime news outlet).
The supplied evidence contains lines from one character only, and no creator or publisher statement with a verifiable source. This section will not add a second speaker until one is documented.
The implication: The lines frame the symbol-of-peace idea, but they do not settle any of the open questions above.
Where the answers stand
Most of the heated debate sits in the open questions, not in the lineage, so the unresolved points deserve the most scrutiny. Fans who repost an unchecked claim spread its error, so they should confirm it against the chapter text or label it unverified.
