One Piece — Luffy's Family
Luffy's blood, foster, and sworn-brother family across three generations of people the World Government really wishes didn't exist.
Luffy’s bloodline spans three generations of people the World Government really wishes didn’t exist. His mother has never been named or shown, which is conspicuous in a world where Oda usually answers these questions eventually.
The full tree
Across blood, foster, and sworn-brother ties:
| Relation | Name | Affiliation |
|---|---|---|
| Grandfather | Monkey D. Garp | Marine Vice Admiral — the “Hero of the Marines” |
| Father | Monkey D. Dragon | Leader of the Revolutionary Army |
| Mother | Unknown | Never shown or named in canon |
| Sworn brother (older) | Portgas D. Ace | Son of Gol D. Roger; 2nd Div. Commander, Whitebeard Pirates. Died at Marineford |
| Sworn brother (older) | Sabo | Chief of Staff, Revolutionary Army |
| Foster guardian | Curly Dadan | Mountain-bandit boss Garp entrusted the boys to |
The sworn-brother relationship isn’t casual — it’s a sake-cup ritual the three did as kids on Mt. Colubo. In-universe it carries the same weight as a blood tie, which is why Sabo’s reveal in Dressrosa lands so hard.
