Fiero is an evil wizard, a Malvago, who appears in the animated series, Elena of Avalor.
In Spellbound he shows up at Mateo's royal wizard coronation, having gained access by magically adding his name to the guest list when Gabe was distracted and claiming to be a friend of Mateo's grandfather Alacazar. In truth, the two were sworn enemies, and Fiero seeks to gain a book called the Codex Maru in order to become the most powerful wizard in the world. Luckily, Alacazar hid the Codex Maru deep in the palace, leaving behind a series of riddles.
He turns the guests (excluding Mateo, Gabe, Princess Elena and Naomi Turner) to stone, and the group needed to find the Codex Maru and brew a potion to reverse the process, as the spell would be permanent by sunrise. Fiero followed the group from behind to avoid solving the riddles. Eventually he cornered them once they found the book and brewed the potion, and promised to leave if they gave it to him. They surrendered the book, and he turns Gabe and Naomi into stone, losing the potion to them.
Naomi and Gabe are restored, and Mateo confronted Fiero in the royal garden. Luckily, Mateo was faster and cast the same spell as him, turning the wizard to stone. Mateo manages to turn everyone in the castle back to normal, while Fiero is possibly stuck as a statue forever due to the spell's effects being permanent after sunrise.
Fiero remained in his petrified state until the Season 2 episode, "Rise of the Sorceress", where a Reversal Potion that Mateo was creating is stolen by Carla Delgado in disguise as "Rita Perez", which Shuriki uses to revive Fiero. Though he is still upset at Shuriki for banishing him from Avalor some years ago, he agrees to help her break into the Royal Treasury to steal the jewel from Queen Lucia's Carnaval Tiara in return for getting Shuriki's aid with stealing the Codex Maru back from Mateo. They succeed with getting the jewel, which Shuriki uses to forge a new wand for herself, but an attempt to steal the Codex Maru results in Mateo saving it, while Fiero escapes with a few blank pages. As they take their leave, Fiero, Shuriki, and the Delgados are confronted by Elena, horrified to see her sworn arch-enemy still alive, and being reminded of the fateful day when Shuriki murdered King Raul and Queen Lucia. Mateo is able to pass Elena the Scepter of Light, allowing her to fight Shuriki on even ground, resulting in where she manages to destroy Shuriki's new wand. Realizing the Scepter is too powerful, Fiero suggests they retreat, knocking down the chandelier he froze earlier to provide a distraction to allow the villains to escape. Once in the woods, he reveals the hidden writing on the pages he stole from the Codex, revealing a way to defeat Elena, but only provides Shuriki the details under the agreement that when she takes over Avalor again, Fiero will be her Royal Malvago, which she agrees on, before they make good their escape in Shuriki's carriage before Elena and the others can find them.
It is revealed in the following episode, "Shapeshifters", that the pages that Fiero stole were clues leading to the dark counterpart to the Scepter of Light, the Scepter of Night, which Alacazar broke up and left riddles to finding in the Codex Maru, along with concealing the information with a spell that hid the information to begin with, hence the pages being blank before Fiero reverses the spell with his Malvago dark magic. Using the clues and riddles, Fiero intends to find the pieces so Shuriki can use the Scepter of Night against Elena and the Scepter of Light.
In the next episode, "The Scepter of Night", using the information in the pages he stole, Fiero leads Shuriki's group to the abandoned capital of Tepet Muul, location of the first piece of the Scepter of Night. However, there is unrest in the group as Victor and Carla are still upset over how Fiero will be of a higher rank than them when Shuriki takes over Avalor again. When Carla and Victor locate the pyramid matching the riddle, Shuriki's group run into Elena and her group at the summit, including Gabe, Mateo, Naomi, Skylar, Luna, Migs, and Dulce. Fiero makes a plan to acquire the first piece, and has Carla and Shuriki retreat to their carriage to act as a decoy, hoping to force Elena into going after them rather than the scepter piece when she sees them flee. However, while they do that, Fiero slips inside, hoping to be led right to the piece by Mateo. However, he is frustrated when he finds Victor came with him, still hoping to get one up on Fiero and gain better favor with Shuriki. When Mateo and Elena find the piece, Fiero and Victor attempt to escape with it, leading to a fight outside over possession of it with Gabe, Naomi, and the Jaquins. Despite Victor and Fiero's best attempts to get the piece, Elena gets hold of it, but as she dives at them to attack, Fiero casts a spell to create a smokescreen so he and Victor can escape. Returning to Shuriki's carriage, they report on failing to get the first piece, but know the riddle leading to the second one. After Carla then adds on that they can always get the first piece back from Elena when she comes for the second one, Fiero and Victor struggle into the carriage as they continue to quarrel, before Carla drives it away once everyone is on-board. They are unaware that Elena and her friends are already preparing to go after them as well once they decipher Alacazar's next riddle to the second piece's location.
Long ago Fiero was supposed to be the next royal wizard. However, the king appointed Alacazar instead, making Fiero angry. Fiero became an evil wizard looking for revenge.
