The Eye of Wdjat in its two forms; with and without the teardrop and tail
The Eye of Wdjat, also called the Eye of Anubis by Upper Deck Entertainment, is an ancient Egyptian symbol, appearing various times throughout Yu-Gi-Oh! media. In Egyptian mythology, Wdjat was the protector of Lower Egypt, and the eye symbol used by her was slightly altered to create the Eye of Horus and later the Eye of Ra.
The symbol has two forms; one featuring an eye, teardrop and tail and one featuring just an eye.

In the Toei anime, the Eye of Wdjat appeared on Dark Yugi's shadow, after Yugi Mutou complete the Millennium Puzzle.
During Joey Wheeler's Duel against Johnson, he played a card which involves flipping a coin, and one of the sides had the Eye on it.
The "Dark Magician Girl" Summoned by Mana and featured in Yu-Gi-Oh! GX has an Eye of Anubis replacing her hexagram jewel (red jewel in the dub), distinguishing her from the card.
Cards from Series 2 onward have an Eye of Anubis Hologram in the lower right-hand corner, featuring the incomplete Eye of Wdjat.
