The Straw Hats show Vivi their ‘X‘ marks as a silent farewell and a sign of camaraderie to her. The X Mark is something the first six Straw Hats (Luffy through Chopper), as well as Nefertari Vivi and Carue, had on their left forearms.
Regarding this, will Luffy get a tattoo?
No Luffy doesn’t have any tattoo on his body. As you’ve mentioned Marineford arc so maybe you’re talking about the scar he got from Akainu on the chest.
Correspondingly, what is Ace’s tattoo? He had a tattoo on his back of the Whitebeard symbol—purple bones formed in a cross behind a purple skull with a white mustache—that he described as his pride and joy. Ace had another tattoo on his upper left bicep that spells “A S CE” vertically. The “S” crossed out is a tribute to Sabo as that’s his jolly roger.
