Did Luffy Really Say “Forgetting Is Like a Wound”?

No. Monkey D. Luffy does not say "forgetting is like a wound. The wound may heal, but it has already left a scar" anywhere in One Piece: not in the manga, not in the anime, not in a film, and not in either English dub.

The verdict

Fabricated. The tell is uniformity: every post carrying the line carries it without a chapter, an episode or an arc, and on the question-and-answer pages where people ask when he said it, nobody answers. A search of all of Wikiquote for the phrase returns zero results, across the One Piece page and every season page beneath it. Screen Rant's ranking of Luffy's best lines, which reaches as far as chapter 590 for material, does not include it. That is what absence looks like for a line that is supposed to be famous.

Where it probably came from

We could not find an author, and this page will not invent one. The thought underneath it is not foreign to One Piece. Dr. Hiriluk, in the Drum Island arc, says that a man dies when people forget him, a line that is real, sourced and on his page. The fabricated sentence reads like that idea, restated as a greetings card and moved into the mouth of the character people search for. That is a pattern this site has seen before: a real theme drifts onto the most famous face in the series.

Why it stuck

Because it is sad in a general way, and Luffy after Marineford is the saddest most viewers have ever seen him. The line gets pasted over images of him grieving Ace, and the picture supplies the context the words lack. But the real Luffy of that arc does not talk like this. His response to loss is not a reflection about scars; it is a collapse, a two-year training pact, and a hidden message sent to his crew. The sentence is the kind of thing a fan would say about Luffy, not the kind of thing Luffy says.

What he actually says

The lines that are his are shorter and louder. In the first episode he tells Coby he is going to be King of the Pirates, and that line is on our Luffy page with its source. If you want a Luffy line that is real and is about the future rather than memory, "if you don't take risks, you can't create a future" is genuine, from the second film, and has its own page.

How we checked

The verification process requires a primary or editorial source before a line is treated as real; this one has neither. We searched Wikiquote in full and read the editorial rankings, and found it in neither. It joins the fact-check database as fabricated, and if a reader can point at the chapter, the address is on the contact page and the verdict will change the same day.
