I do not own One Piece !
Here's a theory about;
Subject: Tattoes
Source/Inspiration: One Piece, the manga
Theory: Sorry for the long abscence, I've been fooling around with A-chan or writing on 'These Familiar Streets' or having a writer's block 8D
But here I am with a new theory! And that is, Trafalgar Law and Portgas D. Ace went to the same tattoo-artist. Cue, Ace's tattoo on his left upper arm is spelled with ASCE with a X over the S while Law's knuckle-tattoos; D, E, T and H misses an A to be understandable. Maybe Ace's hunt for Blackbeard took him to the North Blue where he visited the studio and walked out with a misspelled tattoo?
PS: I took too much credit last time, it was A-chan who found the the info and put it together with Shanks. But I did come up with that about Buggy!
