'''Mickey Mouse''', formally referred to as '''The King''', '''Your Majesty''', or '''King Mickey''', is the king of [[Disney Castle]] and a recurring character in the ''{{c|Kingdom Hearts|series}}'' series. He acts equally to Queen [[Minnie Mouse]], and is close friends with [[Donald Duck]] and [[Goofy]], who act as his close assistants.

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.

[[File:Another Keyblade Wielder 01 KHBBS.png|thumb|Mickey faces Vanitas along with Ventus.]]

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.

[[File:The King's Memory 04 KHII.png|thumb|Mickey consults Ansem the Wise and discusses the worlds' safety.]]

After the barriers between the worlds shatter, causing meteors to fall from the sky, Mickey realizes the threat that the Darkness presents. Mickey seeks help for his concerns and the danger he expects. Inspecting the meteors, Mickey found they had a similar property to the [[Star Shard]]. Gathering up enough of the raw material, Mickey built his first [[Gummi Ship]], using it to travel in search of any world that was in danger of the Darkness. This eventually brought him back to [[Radiant Garden]], where he befriended its ruler [[Ansem the Wise]]. They would discuss many topics.   

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}}

[[File:The World of Darkness 02 KHRECOM.png|thumb|Mickey's light reaches Riku's heart and protects him from Ansem's darkness.]]

 

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.

[[File:Mickey and Riku-Ansem 01 KHD.png|thumb|Mickey promises Riku not to tell what has happened to him.]]

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.

|If Sora falls in battle against certain enemies, the King will arrive to stall the enemy and restore Sora's health.

[[File:The Truth About Ansem 01 KHII.png|thumb|Mickey reveals to Sora, Donald, and Goofy the true identity of Ansem, Seeker of Darkness.]]

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.

[[File:Under Mouse Arrest 01 KHREC.png|thumb|As Heartless suddenly appear inside Disney Castle, Mickey summons his Keyblade to fight them off.]]

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.

[[File:The Mark of Mastery Exam 01 KH3D.png|thumb|Mickey, Donald and Goofy watch Yen Sid prepare Sora and Riku for their Mark of Mastery Exam.]]

 

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.

At the Mysterious Tower, Yen Sid suggests that Mickey and Riku find clues in the worlds Aqua had previously visited, as well as to visit Merlin for new Keyblades. In Radiant Garden, Mickey and Riku realize that Ansem's apprentice, Xehanort, was actually a possessed Terra. They then discuss the replica project with [[Ienzo]].

 

Without any new leads to her location, Mickey and Riku travel back to the Dark Margin to pick up Aqua's trail. When Mickey is attacked and trapped within the Demon Tower, [[Anti-Aqua]] reveals herself and claims Mickey's Keyblade, planning to use it to return to the Realm of Light while leaving the two guardians trapped in the Realm of Darkness. Mickey and Riku are saved by Sora, who defeats Anti-Aqua and frees her from the darkness.

After Ventus is awoken by Aqua and Sora, Mickey meets with the now-complete seven guardians of light at the Mysterious Tower, where Yen Sid instructs everyone to rest for the day and prepare for the final battle the next day.

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.

In the Skein of Severance, Mickey faces off against Xemnas, Luxord, Larxene, and Marluxia. When Sora joins the battle, Xemnas powers up Luxord and leaves. Luxord traps Mickey in a card and battles Sora for Mickey's freedom, but Sora frees Mickey by defeating Luxord. Mickey helps Sora defeat Marluxia and Larxene and chases after Xemnas, telling Sora to assist the others.

Mickey and Riku are joined by Sora at the Tower of Endings, where they defeat Young Xehanort, Ansem, and Xemnas. Master Xehanort then slays Kairi, forcing Sora to attack him. In anger, Mickey attempts to cast Ultima, but Xehanort counters with Stopza and uses the clash against him to forge the χ-blade. Despite being frozen in time, Mickey is able to contact a future version of Sora, explaining that Xehanort had merely scattered the fragments of Kairi's heart and telling Sora to collect the fragments to save her.{{storylink|Kingdom Hearts III Re Mind}} After the time freeze wears off, Mickey explains his plan to use Xehanort's ability to move through time against him and trap and defeat him. Mickey attempts to enlist Aqua and Riku to help him do the job, but Sora, Donald, and Goofy intervene and convince Mickey to let them finish off Xehanort while he and the other guardians close Kingdom Hearts.

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}}

After Master Xehanort's defeat, Mickey and the other guardians follow their hearts to Sora, Donald, and Goofy. After Xehanort hands Sora the χ-blade and admits defeat, the other guardians completely close Kingdom Hearts and return to the Keyblade Graveyard. Sora announces his desire to save Kairi using the Power of Waking. Mickey tries to warn Sora not to as he might lose his heart in the process, but Riku convinces him to believe in Sora. Mickey then wishes Sora a safe journey.

After Sora's departure, Mickey, Donald, and Goofy return to Disney Castle with Yen Sid. Mickey reunites with Queen Minnie and Pluto, where he then watches fireworks in celebration of Xehanort's defeat. Mickey then travels to Destiny Islands and soon witnesses Sora fading away as a result of misusing the power of waking.

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.  

While Donald and Goofy travel to the Land of Departure, Twilight Town, and Radiant Garden to inform their friends about what they discovered and Kairi continues her training under Aqua, Mickey is tasked with discovering the connection between the ancient Masters and the new world, suggesting to begin his search in Scala ad Caelum.

[[File:Mickey Mouse (KH) DI3.png|thumb|Mickey wearing his ''Kingdom Hearts'' outfit in ''Disney Infinity 3.0''.]]

As king of Disney Castle, Mickey is much more responsible and dutiful. He commends 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.

The King appears in ''Kingdom Hearts Chain of Memories'' as a [[friend card]] in ''Reverse/Rebirth''. His card has 12.5% chance of appearing during battle if available. When used, King Mickey performs [[MM Miracle]], which heals Riku, stuns and deals damage to all enemies, and reloads Riku's deck. Stocking multiple King Mickey cards enhances the effect of MM Miracle, increasing the amount of health restored and damage done to enemies. Amongst using enemy cards with healing effects, such as [[Oogie Boogie]], Mickey's friend card is one of the few methods in which Riku can heal. In ''Kingdom Hearts Re:Chain of Memories'', Riku has two new sleights. He can perform the Holy Burst and Inverse Burst Sleights with King Mickey, in normal and Dark Mode respectively, in which Mickey hovers and shoots orbs of light from his Keyblade.

In certain boss battles, if Sora is defeated, an alternate menu option will appear. Instead of the normal "Continue" and "Load Game," Sora is then given the options "I won't give up!" and "It's all over..". If the former is chosen, the player will be able to temporarily play as Mickey. This can happen a number of times in one battle.

In battle, Mickey can perform a combo [[attack]] with {{button|x}} and cast [[Pearl]], a magical attack that damages the opponent with a homing ball of light, with {{button|square}}. He can also jump with {{Button|c}}, and can use {{Button|t}} to perform the [[D-Charge]] Reaction Command, which slowly charges his Drive Gauge; the process is sped up during [[MP Charge]]. Once the Drive Gauge is full, Mickey can activate [[Healing Light]], which will fully recover Sora's HP, [[MP]], and Drive Gauge as well as switch the player back to Sora. If Mickey is defeated before using Healing Light, Mickey will instead use a Hi-Potion to heal Sora so that he regains half of his HP, although his MP and Drive Gauge will remain the way it was before he was defeated.

While Mickey can deal damage, he lacks a finishing move, meaning he cannot land the finishing blow required to defeat a boss. However, Mickey is very powerful and one could use him to damage the boss to the point where Sora need only land a finishing blow to finish the battle after reviving him.

Mickey can be playable during the following battles:

Mickey joins Aqua as a party member, although he does not visit prior areas where Aqua was alone. He has the ability to use a team attack with Aqua called {{c|Wayfinder|Style Change}}.

Mickey serves as a party member to Riku in their first visit to the Realm of Darkness. He mostly behaves identically to how he does in ''0.2''. Riku can use the [[Double Duel]] Situation Command to team up with Mickey and perform spinning attacks of light and darkness.

Mickey Mouse was created by Walt Disney and Ub Iwerks in 1928. Although it is commonly thought that ''Steamboat Willie'' was his first cartoon, it was actually ''Plane Crazy'' where he made his debut six months before, albeit in a test screening. The reason why ''Steamboat Willie'' premiered was because it was the first cartoon in history which had synchronized sound. Since then, Mickey Mouse has become one of the most recognizable symbols in the world, existing for over 95 years as the mascot of The Walt Disney Company.

 

On May 18, 2009, Mickey's first voice actor for ''Kingdom Hearts'', Wayne Allwine, passed away from complications due to diabetes. ''Kingdom Hearts 358/2 Days'' became Allwine's final performance as Mickey, and the English versions of the game were dedicated in his memory. Mickey's current voice actor, {{w|Bret Iwan}}, gave his first full performance as Mickey in ''Kingdom Hearts Birth by Sleep'', and has since reprised the role in later ''Kingdom Hearts'' games.

While Mickey's personality has varied greatly over time, his codifying character traits are a cheerful, gung-ho personality and a love for a good time, to the extent of being naive and easy to manipulate at times. Mickey also tends to be the voice of reason among his friend group, trying to corral and focus the antics they cause. However, Mickey himself is not above causing commotion, and often has a rebellious nature in the face of adversity, always coming up with a scheme to get everyone out of a mess. Despite the problems he may cause, Mickey truly cares for his friends and sees to their safety and happiness at any cost, even at the expense of his own health and sanity.
