- “Don't worry, I have a few tricks up my sleeves.”
- ―Mateo to Naomi
Mateo de Alva is a major character from the Disney Channel animated series, Elena of Avalor. He is a wizard-in-training, who is later promoted to the Royal Wizard of Avalor, and one of Elena's closest friends.
As the grandson of Alacazar and a wizard-in-training, Mateo is very interested in all things magical, be they spells, creatures or items. He is constantly seen trying to perfect his spells, yet sometimes his self-doubt and overly cautious nature can keep him from doing so. Yet if Elena and/or friends need him to, he will put all his fears aside and protect them, sometimes whether they want him to or not, with his magic. He can be clumsy and fumble up his spells from time to time as well. However after his friends help him reclaim the Codex Maru, and Elena shows her belief in his abilities, he gains a greater sense of self-worth and proves to be a powerful Royal Wizard, defeating Fiero in a duel.
Mateo has a slim figure with tan skin, brown hair, and hazel eyes. He typically wears a teal vest with a white undershirt, khaki pants, brown boots, and a red neckerchief. In his wizard robes, he wears a long maroon red robe with a hoodie.
Magical Aura: His innate mystical aura and magic energy is colored a light orange that appear around the things he magically moves telekinetically, from objects to people.
Spell-Casting: Having inherited his inherent magical ability and prowess from his grandfather, he has a strong natural affinity with magic and mysticism. He is therefore capable of casting a variety of both basic/low-level and middle-level spells of nearly all types of good/light magics. Upon stumbling on the secret workshop underneath the royal sorcerer's chamber, he begins to further develop and strengthen his magic in order to cast topmost spells of supreme magics, which the spirit of his grandfather Alacazar refers to as being on the "master wizard" level.
Elemental Magic: Like all wizards, witches, sorcerers and sorceresses of good or evil qualities, Mateo is capable of magically generating and controlling the classical elements- Water, Fire, Earth, Air, Light, and Aether/Quintessence.
However, he never wished to stoop low enough to utilizing the elements of Nether and Shadow/Darkness/Dark, which is mainly associated with those who dabble in the most evil of magical arts (namely Shuriki, Fiero, Chatana and Ash Delgado).
Mateo first appears when Princess Sofia of Enchancia arrives at his house. He overhears Sofia talking to his mother Rafa about summoning Alacazar's chanul. Mateo walks up to her and questions her about her magical knowledge. Sofia revealed that Alacazar sent her. Hearing this, Mateo deduces that the necklace Sofia's wearing is the Amulet of Avalor and takes Sofia down to his workshop. Once there, Mateo reveals that he's been training himself to become a wizard in secret using Alacazar's old things because Shuriki outlawed magic when she took over. He then summons Alacazar's chanul: Zuzo. Zuzo tells them that, in order to free Elena, Sofia has to wrap the Amulet around Shuriki's wand and put both on the Crown of Aziluna. When Sofia decides to get Shuriki's wand by dancing with Shuriki, Mateo is doubtful the plan will work since Shuriki outlawed dancing when she took over but goes with her back to Avalor Palace. When Sofia comes back with the wand, Mateo is impressed. Together, they fly to the Temple of Aziluna where Sofia does as Zuzo instructed and frees Elena. Mateo introduces himself to Elena and together they fly back to Avalor Palace. After Elena fails to defeat Shuriki on her own, they go back to Mateo's house where Rafa gives them the spell that will free Elena's family. After Mateo frees Elena's family, he then helps her defeat Shuriki and free Avalor.
Mateo first appears in "First Day of Rule". He first appears when Elena shows up at his house with his friend Naomi Turner. They tell him that Elena's sister was abducted by ship thieves and, thanks to one of the books of his grandfather, Alacazar, he identifies the thieves as Noblins. They succeed in rescuing Isabel and later Mateo watches Elena select Naomi to join the Grand Council of Avalor.
In "Spellbound", Elena selects Mateo to fill his grandfather's robes as Avalor's new Royal Wizard. At first, Mateo doesn't believe he's up to the task, mostly because most people don't believe in him but after he obtains the Codex Maru and defeats Alacazar's old enemy, Fiero he proves especially to himself that he was a good hire.
In "The Scepter of Light", he attended the solar eclipse with the Kingdom of Avalor, but Orizaba the Moth Fairy returns to bring eternal night to Avalor using the Eye of Midnight. Mateo goes off to pursue her with Elena not far behind. When she uses her scepter it drains her energy away. Worried, Mateo carried Elena back to the palace to discover that using it repeatedly drains the user's energy and is one of the downsides of the scepter. After Orizaba has been defeated, Elena asks him for help on learning how to use it without passing out.
In "Wizard-in-Training", it has shown that Mateo has grown in his confidence as a wizard and gains an apprentice named Olivia. At first, he has a little trouble teaching but soon learns that he has to guide her every step of the way and admits to himself that he still has a lot to learn.
Mateo continues to aid Elena as Royal Wizard after learning of Victor and Carla Delgado having returned to seek revenge for their earlier defeat. When he learns that they are heading to the abandoned capital of Tepet Muul to retrieve the Jewel of Maru, he and Elena, despite it being Dia de Los Muertos, set off in pursuit of them. He finds the Delgados, but is overpowered and loses his tamberitia to Victor. He later retrieves it with Elena's help and returns to the capital, realizing they missed the celebration, but Elena knows she'll see her parents again next year.
Later, he works on a Reversal Potion that he intends to use to restore Fiero to flesh and blood. However, he is unaware that the person he explains this to, Rita Perez, is really Carla Delgado in disguise, who passes this information back to Shuriki, who makes plans to acquire the potion for herself to revive Fiero and recruit him to her cause to get revenge on Elena and conquer Avalor again.
Shuriki gets her hands on the potion once Carla is able to swipe the key from Mateo's lab right off his neck. It is only later when Mateo discovers his lab ransacked from Carla's earlier search for the Reversal Potion that he is shocked when Fiero, fully revived, appears and attacks him to try and take the Codex Maru. Mateo manages to save the book, leaving Fiero to escape with only a few blank pages. Mateo later arrives in time to save Elena from Shuriki by passing her the Scepter of Light to counter Shuriki's wand and protect her from Fiero. After Elena shatters Shuriki's new wand and Fiero provides a distraction to allow the villains to escape, Mateo gives pursuit on horseback with Gabe, Elena, and Naomi, but lose sight of Shuriki, Fiero, and the Delgados. However, Elena has Gabe summon the Royal Guard to hunt Shuriki and her crew down as they return to Avalor City and the palace.
In the episode that follows, as Elena is told to stay in the palace for her own protection, Mateo has managed to complete his Shape-shifting Potion to turn himself into a Jaquin. After running into Gabe and revealing the potion to him, Gabe joins Mateo and Elena as they head to attend Luna's birthday party with many other Jaquins, including Chief Zephyr. When Elena notices Zephyr leave with Cruz, she and Mateo pursue him to Commander's Rock. Finding nothing of interest there, Elena and Mateo return to the others, only for Cruz to arrive afterward and frame Elena, Gabe, and Mateo for Zephyr's disappearance. Believing him due to their friendship with him, Migs, Luna, and Skylar lock them up, but Elena manages to convince Mingo, Zoom, and Estrella to let them out. After traveling to Commander's Rock and letting Zephyr out, Mateo and Elena pursue Cruz, but Mateo gets snagged in some vines. He later catches up as Elena and Zephyr have captured Cruz, and Gabe, Migs, Luna, and Skylar see to his imprisonment. Back at the castle, Elena asks Mateo about the missing pages from the back of the Codex Maru that Fiero stole, and using the Scepter of Light, they learn of its dark counterpart, the Scepter of Night, and the riddles left behind by Mateo's grandfather Alacazar, that lead to the pieces.
Following the riddles, and joined by Naomi, they travel to the abandoned capital of Tepet Muul to find the first piece. However, Mateo is blinded by pride, thinking that if they get the scepter first, he could become as powerful as his grandfather, maybe even surpass him. However, he ends up in the wrong pyramid at first, and then his pride leads to where he leads Fiero and Victor Delgado to the first piece, leaving him demoralized at his mistake. A pep talk from Elena manages to cheer him up, and he is able to help stop Fiero and Victor from escaping with the piece by saving Naomi, while Elena gets the piece and forces the villains to retreat without it. After Mateo apologizes to Naomi, Gabe, and the Jaquins for his screw-up, they regroup to decipher Alacazar's riddle that leads to the second piece, knowing that Shuriki and her team are heading for it as well.
However, once at the second piece's location in Vallaestrella, the decision is made to have Mateo and Gabe return to Avalor on Migs and Dulce with the first piece while Elena and Naomi get the second and third pieces. However, en route back, Mateo and Gabe are ambushed by the Delgados, now full-fledged Malvagos on Shuriki's order to Fiero, and lose the Scepter of Night's Staff to Victor and Carla. When they return to tell Elena and Naomi, they learn that Shuriki and Fiero got the Mount and Jewel due to Elena's own fault, letting her lust for revenge for Raul and Lucia cloud her judgement so Shuriki has all three pieces now. Luckily, Quita Moz arrives to take Elena to train to unlock the full power of her Scepter of Light, and Mateo sees her off with Gabe, Naomi, and the Jaquins as Elena departs with Quita Moz.
By season three, Mateo and Elena decide that it might be time for Mateo to reunite with his grandfather, so they contact Princess Sofia in Enchancia, asking that she send The Lost Princess of Avalor back home to Avalor. Sofia agrees, and once the book is returned to them, Mateo reunites with Alacazar, only to learn that the spell that Alacazar cast to turn him into the book is wearing off. When the book disintegrates, he'll die and go to the Spirit World. Not wanting that to happen, Mateo works with his grandfather to concoct a potion that saves Alacazar, but tragically, he sacrifices himself to protect Mateo from Ash Delgado and a now fully evil Esteban, though his sacrifice allows Mateo and Elena to get the stolen Scepter of Light back from them.
Mateo is then asked by Elena to train the best of her Royal Guards to use magic to fight Ash and Esteban when they return, and though he has Elena and Naomi take Doña Paloma with them to find what he needs to make more tamberitias, he soon has problems of his own when Gabe loses patience with the training, and a protege wizard makes a mess of Avalor Palace that Gabe and his guards can't fix with their inadequate magic training. Mateo is able to set things right before Elena and Naomi return with what he needed and noticed anything.
In Sweetheart's Day, Flo and Armando go to Mateo's workshop and whip up a potion to make Armando's singing better. Unfortunately, all it does is make everyone but him sing nonstop. Mateo manages to make a reversal potion with an ingredient from Dona Paloma's shop. However, for it to work, Armando needs to sing from his heart. Armando does so and breaks the spell.
In the Lightning Warrior, Mateo alongside Naomi encourages Elena to give Victor and Carla Delgado a chance to help her free Ixlan the Lightning Warrior. Mateo uses a reversal potion to revive Victor from a solid stone statue. Later, when Elena, Naomi, Victor and Carla return with Ixlan, Mateo reverses the spell that made Victor and Carla Malvagos and they become good wizards.
In To Queen or Not to Queen, Mateo is seen as a jester in the alternate reality. After Elena convinces Gabe and Mateo to take part in the King's Challenge, King Esteban declares that Gabe must fight against Captain Higgins and Mateo against the royal wizard, The Great Bronzino. Bronzino deflects Mateo's attack spells but when Gabe defeats Higgins, Bronzino gets distracted, allowing Mateo to defeat him. Despite this, the king chooses the other contestants over Gabe and Mateo because they paid him money. When Elena confronts the king about this, he has her thrown in the dungeon. Mateo, Gabe and Naomi feel sorry for Elena because she was only trying to help them. Mateo and Gabe manage to break Elena out of jail, and they all rally against the king.
By the series finale Coronation Day, Mateo has learned several master-level spells. He was able to cast a spell that could get past Ash's cloaking spell to reveal their location. A battle occurs in Coronado, and Mateo freezes Pili to ice. Elena's group easily overpowers Ash's group, and all, except Ash and Esteban, are taken prisoner. However, Ash manages to release the Four Shades of Awesome, forcing Mateo and the others to retreat, while Elena and Ash went to the Spirit World. Mateo assists Isabel with defending Avalor from the Four Shades of Awesome when they attack with Esteban. Mateo distracts Hetz, enabling Isabel to place a metal rod on his head, causing Hetz to electrocute himself. However, when Cahu enters the palace and tries to strike Mateo, he flees with Gabe, Naomi and Isabel to his basement. When Elena returns with reinforcements from Vallaestrella, Mateo enchants Gabe's sword enabling it to paralyse two of The Shades, Vuli and Yolo, with one touch. Mateo then send Vuli and Yolo back to the Spirit World , but as he and Gabe exchange a high-five, they are turned into a stone tablet by the most powerful and dangerous member of the Four Shades, Cahu the Time Shade.
Thankfully, Elena is able to revive them after Esteban sacrifices himself to take a shot Cahu made at Elena to turn her into a stone tablet and takes the hit himself, and when she forgives him, it awakens her emotional magic, allowing her to undo all of the Four Shades' damage to Avalor. Once Elena and Esteban defeat Cahu and banish her back to the Spirit World to join the other Shades, Mateo attends Elena's coronation with everyone else, including the Royal Family of Enchancia. After her crowning, Elena names Mateo the Master Wizard of Avalor, and he joins in the celebratory dance afterwards.
- Mateo's tamborita is inspired by the drums used by the Mapuche "Machi" (shaman) in Chile. His spells have Mayan glyphs integrated into them.
