Editing Mickey Mouse

Originally a ship's hand working with Captain [[Pete]] at [[Timeless River]], Mickey became a student of the [[Keyblade Master]] [[Yen Sid]]. After completing his training and becoming a Keyblade Master himself, Mickey travels to other worlds to battle the forces of [[darkness]]. Once believing that darkness had to be eliminated, he eventually realized that light and darkness are interdependent and cannot exist without the other due to his encounters with [[Riku]], whom he forms a strong bond with throughout the series.

Mickey is an important figure in the conflict with [[Master Xehanort]], and was later one of the first to notice the threat of the [[Heartless]], inventing the first [[Gummi Ship]] to travel to other worlds to fight against the monsters.

While using the [[Star Shard]] to search for [[Donald Duck]] and [[Goofy]], Mickey, [[Chip and Dale|Chip]], and [[Chip and Dale|Dale]] are unknowingly brought to the past by unknown means,<!--Mickey is wearing KH2 clothes and wielding Starseeker--> and land in [[Daybreak Town]]'s [[Market]] just in time to save the [[Player]] from a swarm of [[Wizard]]s. Learning that Player is trying to help Donald and Goofy rebuild their [[Gummi Ship]] to return home, the King sends Chip and Dale to help finish the ship. Mickey speculates that a force other than his [[Star Shard]] led him there, remaining unaware that [[Invi|Foreteller Invi]] is watching him from a nearby rooftop.{{storylink|Quest 60: The Warehouse Pt. 6}}

When he was young, Mickey worked as a deckhand with his captain, Pete. He and Pete sailed the steamboat Willie throughout Timeless River. This past association causes Pete to refer to Mickey as "the Boat-Boy King."

When [[Sora]] comes from the future using a door in the Hall of the Cornerstone, he, along with the future versions of Donald and Goofy, mistakes Mickey for being himself from the future. Four times, Mickey appears in scenes of trouble, either in peril (or appearing to be so), saving the day, or both. On one such occasion, his house is attacked by hordes of Heartless and a mini black hole that sucks up all his furniture. After each time Sora helps him out, Mickey shakes his hand and leads him to another scene of peril.

At another point in time, he finds his way to the [[Mysterious Tower]], where Master Yen Sid takes him in as an apprentice. One day, Master Yen Sid leaves his sorcerer's hat out and Mickey places it on his head, casting spells of all types. By enchanting the brooms, he has them do his chores and eventually decides to take a nap, only to awaken and find that the spell has gone wrong and chaos is running rampant, with the entire tower flooded.

Despite his mistakes, Yen Sid keeps him on as his apprentice and Mickey is eventually able to wield the Keyblade.

Upon regaining consciousness, Mickey returns to the Keyblade Graveyard, where he helps Aqua battle Ventus, who is possessed by Vanitas and eventually guides them to the Mysterious Tower, where they discover that Ventus's heart has left his body. Later, after Aqua leaves with Ventus to find him a safe place, Mickey sorrowfully hands in the Star Shard and his Star Seeker Keyblade, thinking he has failed to reach his goal and disappointed his master, and begins to leave. Before he departs, however, Master Yen Sid hands him back the Keyblade with a smile, showing him that he is indeed worthy of the title of Keyblade Master. Mickey then happily accepts it.

At one point, Mickey visited Ansem to discuss the growing threat the [[Heartless]] posed to the stability of the worlds. Their meeting is interrupted by [[Terra-Xehanort|Xehanort]], who seemingly disturbs the King due to his resemblance to [[Terra]] and having the same name as the Keyblade Master that caused [[Eraqus]]' pupils to vanish. Because of his feelings towards the man and his persistent interest in certain experiments, coupled with the growing threat of Darkness, Mickey advises Ansem to review the research in his lab's computer in case Xehanort continues the research behind his back.

Sometime during these years, [[Scrooge]] and Mickey traveled together to create a transit system. {{storylink|Kingdom Hearts II}} At some point, the [[Villains]] became aware of the King and his allies.<ref>'''''Kingdom Hearts''''', '''[[Captain Hook]]:''' "The brat's friends are the King's lackeys!"</ref><ref>'''''Kingdom Hearts''''', '''[[Maleficent]]''': "The King's fools are here."</ref>

Ten years after the loss of his fellow Keyblade wielders, Mickey takes notice that the stars in the sky are blinking out one after another. Knowing that each star was the light of a world's heart, Mickey realizes that the [[Heartless]] were devouring the worlds. Hoping to stop them, Mickey plans to enter the [[Realm of Darkness]] and find its [[Kingdom Key D|Keyblade]] in order to seal the [[Door to Darkness]]. However, as this task would require at least two Keyblades, Mickey leaves a letter instructing Donald and Goofy to head to Traverse Town to ask [[Leon]] for help to "find [[Keyblade|the Key]]". Mickey called out to Sora in his dreams telling him he would be the one to open the door.<ref>'''''[[Kingdom Hearts Ultimania#Kingdom Hearts Ultimania|Kingdom Hearts Ultimania]]''''', '''The King's Guidance''': "The one calling out to Sora in this scene was King Mickey. The king was searching for one of two keys - the Keyblade of the Realm of Darkness - that was needed to lock a Keyhole in order to prevent darkness from invading through the door to Kingdom Hearts. While he was doing so he anticipated Sora's departure through his dream and gave him advice."</ref> Mickey arrives in [[Traverse Town]] at the same time as Sora.<ref>'''''[[Kingdom Hearts Ultimania#Kingdom Hearts Ultimania|Kingdom Hearts Ultimania]]''''', '''Interviewer''': "In the end of the ending, Pluto has the King's letter. Is that implying that the King returned through the Door of Light?" / '''Tetsuya Nomura''': "Actually, between when he <nowiki>[Pluto]</nowiki> first disappears and then appears again in the ending, he met with the King. The reason why Pluto perked up in Traverse Town was because he felt the King's presence." [https://kh-ultimania.livejournal.com/3508.html Translation via Rasenth].</ref> Keeping himself out of sight, he locates a [[Corridor of Darkness]] after the battle with [[Guard Armor]] and passes through it to the Dark Realm. He is followed by his dog, [[Pluto]], who ends up lost along the way.{{storylink|Kingdom Hearts Re:coded}}

When Ansem attempts to possess Riku after his fight with [[Lexaeus]] in the B4F Exit Hall, Mickey sends his light to drive him off. After Riku emerges from the third basement, Ansem takes advantage of Riku's acceptance of his own darkness to attempt to possess him once again. Mickey's light drives Ansem off once more, and Mickey arrives in person, explaining to Riku that a [[World Card]], leading to [[Twilight Town]], had appeared before him and showed him a path from the Realm of Darkness to where Riku was. After Mickey took the World Card, he went through a Corridor of Darkness constructed by Organization XIII to get to Castle Oblivion.{{storylink|Secret Ansem Report 11}} Mickey meets Riku at the B2F Exit Hall, happy to see Riku chose not to be put to sleep by [[Naminé]], and they speak with [[DiZ]], who seems familiar to Mickey.

King Mickey reunites with Riku in [[The Woods|the Twilight Town woods]], who has taken on the form of Ansem, Seeker of Darkness. Initially perceiving him as an enemy, Mickey readies his Keyblade to attack until Riku calmly ties his blindfold into place, shocking Mickey as he reverts to his true self. Riku assures Mickey that he has gained some control over the darkness, but explains that [[Naminé]] cannot finish restoring Sora's memories because his most important ones, which are of [[Kairi]], are missing. Mickey is left confused, but Riku further explains that the Organization used the memories they stole from Sora at Castle Oblivion to create a [[Xion|copy of Sora]] to do their bidding; if Sora does not get his memories of Kairi back, he will remain asleep. Mickey urges Riku to let him help, but the latter declines. Revealing his plans to face [[Roxas|a member of the Organization]] soon and his insecurity about surviving the fight, Riku makes Mickey promise to guide and protect Sora and their friends once they awaken.

As Sora, Donald, and Goofy have been asleep for a year and remain unaware of recent events, Mickey pays a visit to [[Yen Sid]] to ask him to brief the trio on the threat of the [[Nobodies]]. To help them get to the [[Mysterious Tower]], Mickey rides a train provided by his teacher back to [[Twilight Town]]. Arriving at the train station, Mickey is met by Riku, who gives him the [[Munny Pouch]] that he had stolen from [[Roxas]] in [[The Other Twilight Town]]. Not wanting Sora and Kairi to know about his condition, Riku pleads with Mickey not to reveal his whereabouts or his condition to Sora, and Mickey reluctantly agrees.

At [[Hollow Bastion]], Mickey reveals the truth about "Ansem", but is reluctant to reveal any information on Riku. He then aids the group in fending off the Heartless that [[Maleficent]] has summoned to destroy Radiant Garden. Initially, he orders Sora, Donald, and Goofy to leave Hollow Bastion and leave the Heartless to them, but Donald and Goofy go against his orders when they realize how desperate Sora is to help Leon. He later confronts them after they defeat [[Demyx]], at first appearing angry, but soon simply decides to allow them to help.

When Goofy apparently dies after taking a nasty blow to the head while saving Mickey from the same fate, Mickey swears that the Heartless would pay and permanently discards his Organization XIII disguise. They are later relieved to discover that Goofy was only unconscious. When he and Sora confront [[Xemnas]], he jumps after Xemnas into a corridor of darkness before it closes, thus preventing Sora, Donald, and Goofy from going after him, but since he appears later in Twilight Town, it is apparent that he could not follow Xemnas all the way back to the Organization's base.

Sora and the others meet him in Twilight Town, where they find a way into [[The World That Never Was]] through The Other Twilight Town DiZ had created. When they enter the world, Mickey goes ahead of Sora to look for Ansem the Wise. He eventually finds him and rescues him from a group of Nobodies. Ansem then attempts to use the [[Kingdom Hearts Encoder]] to convert Kingdom Hearts into data, but is unsuccessful and vanishes when the machine explodes.

Mickey then confronts Xemnas with Sora, Riku, Kairi, Donald, and Goofy, and watches as Xemnas opens Kingdom Hearts. Xemnas then blocks out King Mickey and Kairi from participating in the final fight, first by launching a building at him and Kairi, closing the door to Kingdom Hearts, and later closing the dark portal to the Destiny Islands, preventing Mickey, Kairi, Donald, and Goofy from returning to aid Sora and Riku.

After Sora and Riku end the Organization's plot, Mickey waits with Donald, Goofy, and Kairi on Destiny Islands for their return. Once they do, he runs to Riku and congratulates them both for defeating Organization XIII. During the end credits, King Mickey is seen returning with Donald, Goofy, [[Scrooge McDuck]], [[Huey, Dewey, and Louie]], Pluto, and [[Jiminy]] to Disney Castle, where he shares a kiss with Queen Minnie.

Following the digital Sora's time in Traverse Town, he is attacked by Heartless. After disposing of them with the Star Seeker, he tries to leave the library to check the castle, but finds himself locked in, along with Jiminy, Donald, and Goofy. Somehow, they have been transported into the digital journal itself. While in the journal, he joins forces with Data-Sora and the journal itself (in the form of Riku) to dispatch the Heartless and debug the digital world. After defeating [[Sora's Heartless]], who was corrupting the journal, Mickey and his friends are returned to the real world when the debugging is completed, but a message claiming that a door to a new world has opened appears on the screen. Preparing for another adventure, Mickey requests to be taken into the digital world again to solve this new mystery.

Inside, he escorts Data-Sora throughout Castle Oblivion until they encounter the data version of Naminé, who tells them about Terra, Ventus, Aqua, and the reason behind the [[Bug Blox]] corruption, which was caused by the real Naminé when she removed Sora's memories and later restored them.

After everything in the journal is restored, Mickey returns to the real world to write the letter to Sora to tell him about those who need him to heal their sadness, and a new journey is about to begin.

Later on, when Sora and Riku do not return from the Sleeping Worlds at the expected time, Mickey enters and finds Riku in Where Nothing Gathers, using a Stopza spell to freeze [[Young Xehanort]] and help him save the comatose Sora, but Xehanort remains unaffected by the spell and knocks Mickey aside in order to battle Riku. Following the fight, Mickey and Riku meet the revived Master Xehanort, who explains to them the details of his past endeavors and his continuing plans to recreate the χ-blade and restart the Keyblade War. Mickey openly accuses Master Xehanort of ruining the lives of Terra, Aqua, Ven, and Master Eraqus, but Xehanort merely quips that it was their destiny. As Master Xehanort prepares to turn Sora into a vessel for a piece of his heart, Xemnas physically restrains Mickey from rescuing him. Lea arrives in time to protect Sora, and Ansem responds by releasing his Guardian, who grabs Mickey and Riku, but is knocked out by Donald and Goofy. The [[real Organization XIII]] are then forced to retreat to their own time periods, but Xehanort ensures they will all clash again in the future.

The seven guardians of light along with Donald and Goofy arrive at the Keyblade Graveyard where they are greeted by Master Xehanort, Xemnas, Ansem, Vanitas, and Young Xehanort, who taunt the seven guardians of their impending failure. The seekers of darkness then unleash a massive swarm of Heartless, Nobodies and Unversed for the guardians to fight.

After dealing with the swarm, the guardians are soon approached by Terra-Xehanort who proceeds to take out the team. Donald destroys Terra-Xehanort with Zettaflare but collapses due to magic overuse, and the guardians, including Mickey, lose their hearts to a massive Demon Tide. Luckily, Sora is able to save everyone and bring them back to the point before their initial defeat at the hands of Terra-Xehanort.  

The guardians confront Terra-Xehanort again, however, this time Lingering Will fights off Terra-Xehanort. After a massive Heartless swarm appears and is defeated by Sora's usage of the light of the past, yet another horde of Heartless surrounds the guardians. Mickey almost casts Stopza against the horde, however, Yen Sid appears and holds off the Heartless with Donald and Goofy to allow the guardians to proceed to the final fight.

While sealing Kingdom Hearts, Mickey and the guardians are confronted by the [[Replica Xehanort]]s, which Master Xehanort had summoned to prevent the guardians from stopping him. The guardians team up to defeat the Replica Xehanorts, but the replicas send most of the guardians into keyholes. Battered and weakened, Mickey defeats the replicas with the help of future Sora, giving Sora the final piece to save Kairi and saving the guardians. The replicas return as Armored Xehanort, but after Sora and Kairi defeat Armored Xehanort, Mickey joins the other guardians in destroying the replicas for good.{{storylink|Kingdom Hearts III Re Mind}}

Mickey, Donald, and Goofy spend the next year searching for clues to Sora's whereabouts in the worlds Sora has visited with no success.{{storylink|Kingdom Hearts III Re Mind}}

After Kairi awakens, Mickey is informed that Riku has gone to [[Quadratum]] to find Sora. Fearing for Riku's safety, Mickey tries to go after him before being stopped by Yen Sid, aware that they were going into "uncharted waters". Knowing that Xehanort's clue came from during his time as a researcher, he and the group hear Yen Sid recall stories of the ancient Keyblade Masters crossing over into another world and believe Xehanort might have studied it.  

As king of Disney Castle, Mickey is much more responsible and dutiful. He commands the respect and loyalty of his subjects, especially Donald and Goofy. Mickey is very friendly and loyal, always thinking positively while trying to lift the spirits of others. He is always ready to help his friends and tries to protect them at any cost, showing a determination that none could dampen. Mickey always tries to keep the promises he makes to his friends, even when he doesn't always agree with said promises, showing a great deal of loyalty to those who earned his friendship. When he sees his friends get hurt, he becomes surprisingly serious and angry, such as when Goofy appears to be mortally wounded after saving him during the [[Battle of the 1000 Heartless]]. In addition, Mickey has shown a good deal of guilt over the fates Aqua, Ventus, and Terra had faced, believing he was partially responsible, especially with Aqua who was stranded in the Realm of Darkness for years. Despite this, Mickey resolved to save them.

Mickey's valiant nature often pits him against villains who try to hurt his friends and allies or conquer worlds. He is especially antagonistic towards Maleficent, with whom he has clashed multiple times, and towards [[Master Xehanort]], whose actions have caused a great deal of pain and destruction throughout the worlds, including the ruining of the lives of Terra, Aqua, and Ventus.  

Originally, Mickey possessed a biased view of Light and Darkness. He believed Light was always a force of good while Darkness was always evil, never giving the chance to understand them both. However, after journeying with Riku he realized the naivety of his views, seeing that Light and Darkness are interdependent of each other, with all worlds being made of both. Mickey came to accept that Darkness is half of everything and that people are merely scared of the darkness, rather it actually being a force of evil.

While only a few feet tall, King Mickey is an incredibly powerful Keyblade wielder as shown when he defeats three [[Darkside]] Heartless in a single blow, even in the Realm of Darkness where all Heartless are exponentially stronger. Extremely skilled with the weapon, he uses his size and agility to maximize his advantages and wear down his foes, flipping and spinning constantly to attack from all sides and heights, and finishing with wide, powerful strokes of his blade. Mickey's skill in battle is great enough to be able to momentarily hold off a simultaneous assault from Xemnas, [[Marluxia]], [[Larxene]], and [[Luxord]] during the battle at the Keyblade Graveyard.

Mickey is also adept with magic. ''Kingdom Hearts II'' demonstrates Mickey's ability to use the "Pearl" and "Holy" light-based spells. In ''Kingdom Hearts Birth by Sleep'', he is shown to heal Ventus with [[Cure]] after Vanitas nearly kills him. In ''Kingdom Hearts 3D: Dream Drop Distance'', Mickey is shown casting [[Stop]]za, freezing everyone in [[Where Nothing Gathers]] in time. However, according to Riku, using time magic uses a great deal of Mickey's stamina, to the point where it would inhibit his ability to fight normally. In ''Kingdom Hearts III'', Mickey demonstrated that he is able to use the spell "Ultima", however was unable to finish casting due to the intervention of Master Xehanort's Stopza.

During his time as a Keyblade wielder, Mickey has used two Keyblades: Star Seeker and the [[Kingdom Key D]], a Keyblade of the Realm of Darkness. The Kingdom Key D grants him the ability to open doorways between the realms of light and darkness, and he has spent large amounts of time in the Dark Realm. Yet, as a testament to his strong heart, Mickey has never once fought with his inner darkness and can travel through [[Corridors of Darkness]] completely unaffected.

He has rather low HP, average strength, and attack speed but excels in the Magic and Critical areas. He uses his small size to his maximum advantage, swiftly evading enemy attacks while exploiting enemy openings likewise with wide, fast strokes of his Keyblade. His Limit Break is the [[Holy]] technique that he uses in ''Kingdom Hearts II''.
