Gaddison is a character from The Legend of Zelda: Breath of the Wild. She is a female Zora who lives in the Zora's Domain in the Lanayru Great Spring region of Hyrule. She was a member of the Big Bad Bazz Brigade one hundred years ago before the Great Calamity and later went on to become a Zora Knight alongside her old friends Bazz and Rivan.
Gaddison is a pale violet Zora that is notably the same size as most adult female Zora, but she differs in that of her color palette. She is the only Zora in all of the domain with this color. She can be found wearing the same armor that all knights in her species wear, and carries a weapon with her in case of an attack.
Gaddison is a female Zora who speaks in a slightly-masculine tone. As a child, she was a member of the Big Bad Bazz Brigade with Bazz, Rivan, and the Hylian Champion Link who used to play with her and her friends. One century after the Great Calamity, she is shown to have joined the Zora Knights along with Bazz and Rivan. She patrols the bridge that lead to the East Reservoir Lake keeping watch over the Reservoir to raise the alarm if the Reservoir is in danger of overflowing.
Rivan refers to her as "The Heroine", which was presumably a nickname she used as a member of the Bazz Brigade. Like her fellow Bazz Brigade members, she does not hold any ill will towards Link for Princess Mipha's death and treats him like a respected older friend.
During the quest "From the Ground Up", Link can ask Gaddison to come to Tarrey Town due to her name, but she will decline, saying she is a "blood-stained soldier, not a priest" and will suggest Link to go see Kapson.
