Big Sturg Ganna was a male alien gangster who operated in Canto Bight. He sought after the masseuse Lexo Sooger, hoping to acquire him as an asset. At some point Ganna kidnapped Sooger's daughter Lula. He was an amphibious being with a ticklish tail. His body was covered in a layer of blubber that keeps him warm in his native environment, and he liked to spend time in cold water tanks.
