Shark is an evil power-hungry sorceress from the Northern Islands and is the main antagonist of the Sofia the First and Elena of Avalor crossover, Elena and the Secret of Avalor. One faithful day, she invaded Avalor, killed Elena and Isabel's parents and trapped in Elena in the Amulet of Avalor (Sofia's amulet) when she tried to strike her down. She uses a wand, which she can use to zap anyone to their immediate death. She was defeated when Elena broke her wand in half and she aged into an old woman (therefore she also uses her wand to keep herself young) and fell of the balcony of the palace falling to the water. In Elena of Avalor: Realm of the Jaquins, it is revealed that Victor and Carla Delgado stole a gem from Vallestrella to give to Shuriki to regain her youth and also to help her regain her powers and take her revenge of Elena and reconquer Avalor.
