"I am no longer a Master. I doffed that mantle."

—Yen Sid to Terra.

Yen Sid is a powerful sorcerer introduced inKingdom Hearts II, and originally taken from the "The Sorcerer's Apprentice" short in the Disney filmFantasia. He is a retiredKeyblade Master, renowned for his wisdom and command over the arts of magic. Although he is no longer an active Keyblade Master, he still keeps a close watch on the balance betweenlight anddarkness. He was onceMickey Mouse's master, and taught him everything he knows of magic and the Keyblade.

Story[edit]

BeforeKingdom Hearts Birth by Sleep[edit]

Yen Sid was once a Keyblade Master alongsideEraqus andXehanort.^[2] He chose to retire to theMysterious Tower and lay down his Keyblade Master mantle, but remained a powerful sorcerer and continued to observe the balance between light and darkness. He also hoped Xehanort would let go of his fascination with theKeyblade War and theχ-blade.Kingdom Hearts Birth by Sleep

Yen Sid took on the boatmanMickey Mouse as his apprentice, teaching him everything he knows about magic and the Keyblade. At one point, he sent Mickey on a mission to theCountry of the Musketeers.Kingdom Hearts 3D: Dream Drop Distance However, Yen Sid was unable to give Mickey aMark of Mastery exam. After savingPrincess Minnie, Mickey had decided to end his training and instead focus on being king ofDisney Castle.Kingdom Hearts Birth by Sleep

Kingdom Hearts Birth by Sleep[edit]

Yen Sid had become aware of the presence of theUnversed threatening the worlds, just as his former apprentice Mickey had. Mickey returned to Yen Sid to complete his training as aKeyblade Master. BelievingEraqus andXehanort could use the help of another Master, Yen Sid resumed completing Mickey's training. However, after Mickey failed his first test, Yen Sid told him of feelings of dread he had; something terrible would occur soon. The next day, Yen Sid contacted theLand of Departure to warn Eraqus of the threat and to send his pupils out to quell the chaos. Mickey decided to assist without permission and stole aStar Shard to travel the worlds; because Mickey did not fully understand how it worked, Yen Sid remained unable to track him as the shard randomly sent Mickey around the worlds.

Yen Sid converses with Terra about the whereabouts of Xehanort.

WhenTerra visitsYen Sid's tower, he asks him for guidance aboutMaster Xehanort,Vanitas, and the Unversed; Yen Sid advises Terra to treat all three as the same problem. After Terra leaves, Yen Sid muses on his disappointment in Xehanort's continuing folly. Later,Ventus shows up at his tower with aStar Shard, and Master Yen Sid uses divination magic to locate Mickey. However, unforeseen interference prevented Ventus from returning with Mickey.Aqua later returns Mickey to his tower, and Master Yen Sid tells her of Master Eraqus's destruction and that the murder was committed by Terra and Master Xehanort. Sometime after Aqua leaves for theKeyblade Graveyard, Mickey departs to assist her and her friends.

Following Vanitas's defeat, Mickey returns with Aqua and a comatose Ventus. Master Yen Sid finds himself unable to sense Ventus's heart and encourages Aqua to believe in their friendship, which serves as the key to bring him home one day. Some time later, Mickey sorrowfully hands in the Star Shard andhis Keyblade, thinking he has failed his Mark of Mastery exam and disgraced his master, and prepares to depart. However, Master Yen Sid gives him back theKeyblade, showing that Mickey, in fact, passed and became a Master.

Kingdom Hearts II[edit]

Yen Sid prepares Sora for his next adventure.

Yen Sid serves asSora's tutor to what lies ahead of him in his journey. When Sora and company (Donald Duck andGoofy) arrive, he tells them of the enemies that they will face in the near future (Heartless,Nobodies, andOrganization XIII). He also returns theirGummi Ship to them, which he had been safekeeping, and sends them toHollow Bastion.

When Diablo bringsMaleficent's cloak to Flora, Fauna, and Merryweather, causing her to be revived, the fairies rush off to tell Yen Sid. However, by the time Sora and his friends can return to the tower, Yen Sid and the fairies are nowhere to be found.

Kingdom Hearts coded[edit]

Yen Sid warns Mickey of Master Xehanort's impending revival.

After discovering that Sora has the power to save all the lost hearts connected to him, Mickey meets with Yen Sid to discuss their ongoing search for Terra, Ventus, and Aqua. However, Yen Sid shocks Mickey by revealing that the destruction ofAnsem andXemnas has led to the return ofXehanort, and not just a "single one" of him, and which will eventually lead to the return of Master Xehanort. Yen Sid had known that this disaster might come about while he was mentoring Sora, but chose not to disclose it to anyone because leaving Xemnas alive was not an option.[citation needed] As Mickey, the sole surviving Keyblade Master, will not be enough to counter Xehanort's new threat, Yen Sid orders Mickey to summon Sora and Riku to him to undertake theMark of Mastery exam.

Kingdom Hearts 3D: Dream Drop Distance[edit]

Yen Sid prepares Sora and Riku for their Mark of Mastery exam.

Yen Sid explains the full history of Master Xehanort to Sora and Riku and puts them through the Mark of Mastery exam by assigning them to awaken several worlds which remained in theSleeping Worlds following Ansem's destruction to obtain the power of waking, and explains numerous facts such as the nature of theDream Eaters and residents of the sleeping worlds. However, soon after the exam begins, Yen Sid starts to feel that something is going awry.

Later on, when Mickey, Donald and Goofy depart for Disney Castle to confront Maleficent, Yen Sid surmises that the growing darkness in the worlds due to Master Xehanort's coming return may be the reason Maleficent has become strong enough to resist theCornerstone of Light. The trio soon return with the revivedLea, who requests to become a Keyblade wielder. Yen Sid, taken aback, warns Lea of the dangerous path ahead, and has him undergo a magically compressed training session underMerlin andFlora, Fauna, and Merryweather. Eventually, when Sora and Riku do not return from the Sleeping Worlds as planned, Yen Sid realizes that Xehanort devised a means to confront the two in the Sleeping Worlds and sprung a trap on them. He allows Mickey to make his way toThe World That Never Was to save their friends, sending Lea, Donald and Goofy after Mickey as back-up.

Mickey and the others eventually bring Sora's comatose body back to the study, where Yen Sid realizes that Master Xehanort was on to them the entire time. When Riku awakens Sora from his slumber, Yen Sid delivers a sincere apology to the both of them for failing to realize the magnitude of Master Xehanort's plans. Though he commends them both for performing admirably, Yen Sid only declares Riku as a Keyblade Master, since he managed to unlock two Keyholes of Sleep, while Sora failed to resist the darkness and ended up in a magical sleep induced byYoung Xehanort. Yen Sid, however, is visibly stunned when Lea finally manages to summon his own KeybladeBond of the Blaze.

Having realized Master Xehanort's plan to recreate the χ-blade by pitting hisnew Organization XIII against the seven Princesses of Heart, Yen Sid devises a plan to counter Xehanort by gathering seven Keyblade wielders of Light to protect the Princesses, and orders Riku to bringKairi to him to undergo training with the Keyblade she received from Aqua.

Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage-[edit]

Shortly after Kairi's arrival, Yen Sid informs her, Riku, and Mickey of their objective to rescue Terra, Ventus, and Aqua from their fates. He has Mickey inform Riku and Kairi of what happened to Aqua following her fall into the Realm of Darkness. After Mickey explains Aqua's current whereabouts, Yen Sid explains that the real reason why Mickey kept the news a secret was to prevent anyone from entering the Realm of Darkness before it was safe to do so. He grants Riku and Mickey new garments from the three good fairies to shield them from the darkness and assigns Kairi to train with Lea under Merlin's tutelage in the ways of the Keyblade.

Soon after, Sora returns from the Sleeping Worlds, and is instructed by Yen Sid to find a way to restore lost hearts. Yen Sid reminds Sora that the boy has lost his abilities once more and directs him toOlympus Coliseum to train withHercules.

Kingdom Hearts III[edit]

After Sora and the King fail with their initial attempts, Yen Sid advises them on how to continue; Sora travel around the worlds to build up his strength and Mickey to search worlds Aqua went to for a lead. Yen Sid encourages them to find Aqua and continually tells Sora that he cannot help until he regains thepower of waking.

After Aqua and Ven are retrieved and Lea and Kairi finish their training, Yen Sid tells them, Sora, Donald, Goofy, Mickey and Riku to spend the night resting; the following day, theGuardians of Light would face theOrganization at the Keyblade Graveyard to put an end to Master Xehanort's plans.

Yen Sid uses his magical powers to open a pathway for the guardians.

Yen Sid later arrives in the Keyblade Graveyard after a third wave of Heartless,Nobodies andUnversed were called to wear down the guardians for the Organization. Using his magic, Yen Sid repels the creatures with a wall of light, allowing the seven guardians to head into battle, while Donald and Goofy stay behind to back him up.

Following Xehanort's defeat, Yen Sid journeys toDisney Castle with the King, Donald, Goofy andJiminy. They are greeted byMinnie,Daisy, Chip, Dale andPluto as fireworks erupt above to celebrate their victory.

One year after Xehanort's defeat, Yen Sid, Merlin, andFairy Godmother have been discussing Sora's disappearance and conclude that the answer to finding him should be in the dreams of Riku and "the other two".Kingdom Hearts III Re Mind

Kingdom Hearts Melody of Memory[edit]

After Kairi awakens, Yen Sid is informed that Riku had gone toQuadratum to find Sora and halts a flustered Mickey from following him, aware that they were going into "uncharted waters" Knowing that Xehanort's clue came from during his time as a researcher, Yen Sid recalls hearing stories of the ancient Keyblade Masters crossing over into another world and believes Xehanort might have studied it.

He sends Donald and Goofy traveling to the Land of Departure, Twilight Town, and Radiant Garden to inform their friends about what they discovered; approves of Kairi's idea of continuing her training under Aqua, and tasks Mickey with discovering the connection between the ancient Masters and the new world, suggesting to begin his search in Scala ad Caelum.

Design[edit]

Master Yen Sid is a rather severe-looking old man with long, grey hair, bushy eyebrows, and a long, grey beard that parts down the middle. He wears the famous, conical sorcerer's hat on his head. The hat is blue and decorated with several yellow stars and a yellow crescent moon.Fantasia shows that the top of Yen Sid's head is bald under the hat, though he never removes it in theKingdom Hearts series. He wears long, billowing blue robes with sky blue lining, with the insides of his robes being dark red. The whites of his eyes are quite large in comparison to his small pupils, something that is further highlighted by the fact that his eyes are often wide open. InKingdom Hearts Birth by Sleep, there are very small changes to the sorcerer's robes, such as the sky blue lining becoming thicker and the robes themselves being a bit wider.

Yen Sid is seen to wear black shoes in hisBirth by Sleep character model. InKingdom Hearts III, full black boots can be seen for a brief moment when his robe billows from Yen Sid releasing the wall of light magic.

Personality[edit]

While little is known about his life as a Keyblade master, the elderly sorcerer is shown to be a rather stern man. In almost every instance, he is shown to be frowning. But beneath his harsh exterior belies a man who strongly believes in his apprentices no matter how much mischief they may get up to, demonstrated by when he expresses annoyance at Mickey for running off with the Star Shard and recklessly getting lost with it, but then forgives Mickey and awards him the title of Master with an encouraging smile. Despite his outwardly gruff nature, he has displayed a sense of humor, shown when he cracks a smile and points out in a friendly manner how small Sora's clothes have gotten.

Given his past status as a Keyblade master, he is shown to have great knowledge about the properties of the Heart, the Heartless, the Nobodies, the Unversed, and the Dream Eaters. It is he who explains the nature of the Unversed to Master Eraqus, and that of the Nobodies and the Dream Eaters to Sora, Donald and Goofy, and also tells them that as long as darkness exists in one heart, the Heartless will never cease to exist. So powerful and wise is he, that even Terra, Aqua, and Ventus speak to him with utmost respect, despite him not being their master. However, Mickey and Riku merely refer to him as "Yen Sid" without calling him "Master", possibly because they, like Master Eraqus, are also Keyblade Masters (though this is only in the English versions; in the Japanese versions, they still call him "Master Yen Sid" as a sign of respect).

Abilities[edit]

Master Yen Sid is a master of the magical arts, able to perform powerful magic spells comparable toMerlin's. He has shown the ability to teleport, even between worlds, create illusions while training Mickey, and create cosmic smoke to locate a person. He seeks counsel with the stars to predict the conditions of the present and the future, which allows him to gather information about the worlds' condition and to pass it on to his allies.

He has also shown the ability to manipulate and utilize the power of light to an extraordinary extent, as demonstrated at the Keyblade Graveyard, being able to part an immense army of Heartless with a mere gesture of his hands and hold them off long enough to allow the guardians of light to advance through them without any exertion.

He has also shown the ability to manipulate time to an extent, at least as it pertains to the Realm of Sleep, were the laws of time travel, as he is able to revert Sora and Riku back to younger versions of themselves and send them back to a point in time before Destiny Islands was destroyed in that realm for their Mark of Mastery exam.

As a retired Keyblade Master, he presumably still retains the power to use the Keyblade, but does not appear to use it.

Origin[edit]

The great sorcerer first appeared in theFantasia shortThe Sorcerer's Apprentice as Mickey Mouse's master. He was the owner of a magical hat that is apparently the source of his power. In the movie's most acclaimed sequence, Mickey steals the hat and begins to play with its magic. However, as he was warned by Yen Sid, the power of the magic cannot be controlled by Mickey and wreaks havoc. Yen Sid arrives and manages to stop the magical chaos with his own powers.

His name is "Disney" spelled backwards, as a tribute toWalt Disney himself.
