These probably have a deeper meaning...OBVIOUSLY! But for the non-punk-rockers out there, the checkers like on his wrist and fingers (like on the Vans shoes) means Unity. That's why people wear the vans, it means unity (hence the black and white or whatever else color) but that must mean there is a deep meaning to why of course, he exhists and maybe that helps us out a bit. He's wearing somethign that symbolizes unity and if he is the other side of sora's heart, BAM, there ya go!!! I hope this is good information, i'm sure something like this won't be mentioned in the game but I mean, I think it's a good clue so I hope this helps people out with their theories!!!
