Crest of the Gerudo

The Gerudo symbol is an emblem which first appears in Majora's Mask, and has been a recurring element is many other games in the Zelda series. It is frequently seen in connection with the Gerudo tribe. Whether the items with symbols belonged to the forces of evil or not, it is a cameo through the Zelda games. In Ocarina of Time, a precurser to the symbol was used as a marking on various puzzle objects, the Mirror Shield, and it represents the Gerudo. It appeared almost identical to a horizontally mirrored version of the symbol commonly used to represent the Islam faith, but was replaced with the new Gerudo Symbol in GameCube and Virtual Constole versions, likely to prevent offending Muslims.

Master Quest
The symbol appears most frequently in Master Quest. It replaces all instances of the crescent-moon symbol from Ocarina of Time, appearing on the Mirror Shield, as well as on all of the game's floor-switches and blocks. It also features on the Gerudo flag.

Majora's Mask
In Majora's Mask, the Gerudo Symbol first appears within the Pirates' Fortress. After Link has forced Aveil to flee her chamber, a framed picture can be found within the chamber displaying the symbol.

Oracle Series
Both Veran from Oracle of Ages and Onox from Oracle of Seasons display the symbol on their armor. Onox has the symbol emblazoned across his chest plate, whereas Veran displays the symbol wrapped around both of her shoulder pads.

The Wind Waker
In The Wind Waker, the symbol can be found within the Master Sword chamber in Hyrule Castle, beneath the Great Sea. The chamber has seven magnificent stained glass windows, each representing one of the Seven Sages. A slightly modified version of the Gerudo Symbol appears within the window representing Nabooru.

Twilight Princess
The most recent instance of the symbol is in Twilight Princess, where a stylized version features on the red tabard section of Zant's outfit. Also, a slightly altered and simplified version of the symbol can be seen on Ganondorf's cloak.
