~ Fiero casting his spell to transform people into stone.
Fiero is an evil wizard who appears in the Disney Channel animated series Elena of Avalor, serving as the main antagonist of the episode Spellbound. He was later freed in the Season 2 episode Rise of The Sorceress, and served as Shuriki's second-in-command until he was turned to stone again in Song of The Sirenas.
He was voiced by Héctor Elizondo.
He was the rival of Alacazar, as they both competed to be the next Royal Wizard for the royal family of Avalor. When Alacazar was chosen, Fiero swore revenge on him and the Royal Family and became a malvago (a wizard fallen to the dark side).
Several days following the defeat of Queen Shuriki, Fiero returns as he plots to steal the Maru Codex, a magic book that contain one of the most ancient yet powerful spells throughout the land, as it happens to be in the possession of Alacazar and that he's passing it over to his grandson Mateo as the new Royal Wizard. After tricking Gabe into letting him in by putting his name onto the visitor list, Fiero searched Avalor Castle for the Codex while turning a guard into stone. However, Mateo catches up to Fiero's presence, but Fiero turns everyone in the castle into stone, except for Elena and her friends (thanks a dome spell that Mateo casted).
As Mateo tells Elena and the gang about Fiero's past, they read through Alacazar's notebook to find clues about the location of the Codex, so that they can use it to reverse Fiero's spell. Following the instructions, Mateo and the other manage to locate the Codex hidden at the Avalor Bay. However, Fiero reveals to have been following the gang the entire time, as he knew that they would figure out the location in order to reverse his spell.
Fiero threatens to turn Elena and the others into stone unless Mateo hands over the Codex, promising that he would leave. Mateo reluctantly does so, but Fiero reneges on his word by stealing the potion that was needed to reverse the spell. However, Mateo manages to reclaim the potion and gives it to Elena before engaging into a fight with Fiero. At first, Fiero seems to get the upper hand, but as he is about to turn Mateo into stone, Mateo uses his wand to rebound the spell back at Fiero, permanently turning him into stone and ending his plot of terror for good. The kids later use the potion to reverse Fiero's spell to turn everyone in the castle back to normal.
However, Mateo ended up discovering a Maruvian spellbreaker, which Carla stole and gave to Shuriki to use on him. Once he was turned back from stone, he was hesitant to thank Shuriki, as she banished him years ago during her reign over Avalor. Shuriki later assured him that his power will be invaluable in her plot to retake Avalor, and he agreed to help her get the tiara's jewel if he's allowed to obtain something from the Codex Maru. After Shuriki stole the jewel, they went to Mateo's workshop and Fiero later ambushed Mateo while he grabs the Codex Maru. Once Mateo regained consciousness, he took back the codex, but not before Fiero absconded with a set of blank pages.
Fiero joined Shuriki and the Delgados while Elena and Naomi were caught off-guard. As Elena was able to retrieve the Scepter of Light, Fiero launches an offensive attack, which gets blocked by Mateo, only to be dispeled by Shuriki. Once Elena was able to destroy Shuriki's new wand with her scepter, Fiero recommended to Shuriki that they leave as the Scepter was too powerful, so he covers their escape. As they were being persued by Elena and her group, Fiero revealed that the pages he retrieved weren't blank and contained a means to match the Scepter of Light. Fiero tells Shuriki he will share the knowledge, if she makes him the Royal Malvago once they take over Avalor. Shuriki agrees, effectively promoting him to be her second-in-command.
The pages contained information about the Scepter of Night, the Scepter of Light's counterpart that Alacazar hid as it was dangerous if it fell into the wrong hands. Shuriki's party ended up in the abandoned city of Tepet Muul, where the first piece was. As they kept looking, Fiero would search with Shuriki, while the Delgados would check another area. After the Delgados found the correct pyramid, Fiero and the rest went there, only to encounter Elena's group. Fiero attacked them and a fight ensued. Fiero decided that Shuriki and the others go back to their carriage, while he confuses Elena and gets the scepter piece. Once Mateo entered the pyramid, Fiero hid somewhere. Unbeknownst to Fiero, Victor was upset over the fact that Fiero outranked him and went against his instruction to go to the carriage. Fiero, annoyed, tells him to stay out of his way. Once Mateo found the first scepter piece, Fiero and Victor waited to overhear the riddle before ambushing them. Once Fiero grabbed the staff with his magic, Victor stepped in and attempted to deliver the piece himself to Shuriki in order to claim the credit. Outside the temple, a fight ensued between Fiero with Victor and Elena's group and the Jaquins. Although they lost the staff, Fiero and Victor teleported back to the carriage to report back to Shuriki. Fiero then informed Shuriki that Alacazar split the scepter into three pieces.
In Race For The Realm, Fiero then figured out from the riddle that the next scepter piece is in Vallestrella, the valley of the stars. Carla then suggests that Fiero makes her and her father Victor malvagos to be prepared for when they enter Vallestrella. Fiero then tells the Delgados that they can't handle the power. After insults between Fiero and the Delgados were traded, Shuriki asks Fiero how they will enter Vallestrella. Fiero tells them that only Jaquins can open the gateway, but the problem lay in finding a Jaquin willing to take them. Victor then tells him and Shuriki that he know of an outlaw who can provide them the means to do so. The information intrigued Shuriki, much to his chagrin. As Victor directs him and Shuriki to where the outlaw Troyo lives, Mateo and Gabe were spotted with the scepter staff on jaquins. Fiero suspects that if Elena is not with them, then she must be on her way to Vallestrella. After Shuriki tells Victor and Carla to go after the boys, they tell her that unless Fiero makes them malvagos, they can't catch up to them. Shuriki then tells Fiero to make them malvagos, to which he protests that they can't possibly handle the transformation. Shuriki tells him they will find out soon enough, and orders him once more. Fiero then uses his tamborita to transform Victor and Carla into malvagos, to which Victor tells him he will not regret this. Once Carla casts a speed spell on the horses, Fiero replies he regrets this already, and reorients the carriage in the direction Gabe and Mateo are flying. As Shuriki and Fiero head to where Troyo lives, no den was spotted, and Fiero believes Victor might have lied to them, only for Troyo himself to appear in front of them. Troyo then leads him and Shuriki to two rogue jaquins Cruz and Vestia after Shuriki agreed to make the coyote king of the Jungle. With these new evil jaquins, Shuriki and Fiero could now gain entry to Vallestrella.
