Why does Ace's right arm have "ASCE" written with the "S" crossed over?


5 Answers 5


Sabo's Jolly Roger

It's Sabo's Jolly Roger.

Ace had another tattoo on his upper left bicep that spells "ASCE" vertically. The "S" crossed out is a tribute to Sabo as that's his jolly roger.

    It could also be a reference to the letter Ace and Luffy got from Sabo when he sailed out. Sabo himself signed it with "Sabo" and then a cross over a capital S, saying he is out of the "ASL"-crew. While we can all agree that it is tribute to Sabo, I don't see why Ace would specifically refer to Sabo's jolly roger as he never actually saw that flag. So he wouldn't have been able to know what Sabo's flagged had looked like. i.stack.imgur.com/Dhl6e.jpg Jan 21, 2015 at 23:32

I'm answering this because, while the other answers are compelling, I don't see any sources being used here definitively connecting the tattoo with the answer. My answer is basically the same as the others: The crossed out S is a reference to Sabo.

Ace has a conversation with Thatch that confirms the S is a reference to Sabo. From the second volume of the light novel Ace's Story, chapter 5, page 155:

"By the way, Ace... what's with that joke of a tattoo you've got?"


"The X through the S is the symbol of my late brother. That's all."

This seems to indicate that there is an X through the S because it is Sabo's symbol, rather than because Sabo died. Though the reason Ace has the symbol is because Sabo died, as a little homage (Rowan and Kenneth's answers showcase where the symbol is used in a couple of places, and their answers are correct, so check them out). This seems to be confirmed on the what-if cover image of Chapter 596, where Sabo is still alive and Ace does not have the S (as Qiri mentions in their answer, and as is mentioned on the wiki). See below:

Ace without S


The S is a tribute to Sabo. For a cover, once Oda drew Ace, Sabo, and Luffy in their late teens, if the ship incident had never happened, and Ace's tattoo read ACE.

  • The "A" stands for "Ace"
  • The "S (with a cross over it)" stands for "Sabo"
  • The "C" stands for "Crybaby" A.K.A Luffy
  • The "E" stands for "Edward Newgate" A.K.A. "Whitebeard"

Dressrosa Arc spoiler:

The reason for the cross over the "S" is because "Sabo" was thought to be dead by everyone.

    I haven't heard of this being an acronym before. AFAIK it's just his name with Sabo's jolly roger added.

    "C stands for crybaby?" I'm curious, where did you read that?

  • This cannot possibly be true because Ace had the tattoo before he met boarded Whitebeard's ship, as seen in the anime, episode 461 Jul 13, 2018 at 17:41

Ace has the S crossed out because it is a tribute to Sabo.
