Shadi

A very mysterious character from the anime/manga Yu-Gi-Oh! (the original one, NOT 5D or GX). He is considered a minor character, but he plays a very major role in the storyline. Often showing up at the most critical moment in the show to do something extraordinary. There's a long standing argument over who Shadi was when he was alive/in the past in Ancient Egypt. Some think he is the ghost of the High Priest Shada, some think he is simply the ghost of a character never shown, some think him to be Hasan (will not spoil this character). However, some think him to be none of those things and others all three. Kazuki Takahashi left this open to everyone's imagination. It's not worth fighting over, so those who argue should just accept each others' views. He is NOT Muslim, though. He makes it clear that he is not very quickly in the series, though there's nothing wrong with portraying him as partially Muslim.
