Heart

A heart is a recurring element in Disney media and anime media. There are two games that use this concept.

Kingdom Hearts series
A Heart is one of the three parts which comprise a being in the Kingdom Hearts universe, the other two being body and soul. Hearts are one of the key points in the game's mythology, and the antagonists often seek to use them for their own gain.

Construction
What actually makes up a heart is a mystery in the Kingdom Hearts universe. Much research has been done to try and unravel the mystery, most notably by Ansem the Wise and his apprentices. However, this research only served to lower the barriers between worlds, set up the events for Kingdom Hearts, Kingdom Hearts: Chain of Memories, and Kingdom Hearts II, and cause many worlds to be plunged into darkness. It is known, however, that the heart is primarily made up of light and darkness, the latter of which formed due to people's greed. The exception to this are the Princesses of Heart, maidens whose hearts are free of darkness.

The heart appears to be responsible for the composure of memories, will, goals, and ambitions, as is the case in the transfer of Master Xehanort's heart into Terra and the internal struggle of wills inside Terra-Xehanort.

The heart is also responsible for emotions, as beings lacking one, such as the Nobodies, cannot feel emotions.

Tie-in to the Worlds
According to legend, the worlds were one and united through the light in people's hearts. Once these hearts became filled with darkness, however, chaos resulted, and the worlds were separated. It was the light that remained only in the hearts of children that would keep the worlds in existence before they were shrouded in darkness completely.

Ansem's Research
Scholar Ansem the Wise was struck by a great curiosity of the heart and its true nature. He began research on the topic so he could better protect his world from the forces of darkness, together with his six apprentices, and started to write his reports. However when Ansem reliazed that his experiments could bring disaster to the world he stopped all his research.

However Xehanort decided to continue the experiments and realized that when hearts were seduced by darkness, a creature he dubbed a "Pureblood Heartless" was born. He made note of how Heartless acted on instinct, and wished to try creating his own Heartless. To tell them apart from the Purebloods, he dubbed them "Emblems" and christened them with what would later become the Heartless insignia. He made note of how they behaved relatively the same way, continuing to experiment in other areas with which the heart was concerned. He had no idea that he had caused chaos to brew. However when Ansem became aware of Xehanort's activities, he ordered that his research be stopped at once. This strict request would lead to the birth of Ansem and Xemnas, as well as the rebellion of Ansem's other apprentices. Xehanort and the other apprentices' Nobodies would later grow to form Organization XIII, a group that had the sole purpose of unlocking the secrets of the heart.

While Ansem was cast out into the Realm of Nothingness, Xehanort wrote the Ansem Reports. After he put his research and his findings to paper, these reports scattered across the worlds, and were able to help the residents of Traverse Town and Sora in his first journey when it came to learning about and fighting the Heartless. Ansem's experiments on the heart would continue to haunt him even after his escape from the Realm of Nothingness, throughout the story of Kingdom Hearts II, as his reports continued to spawn as the Heartless he had created returned. He was forced to recall his past mistakes and even failed to succeed in avenging his dignity, realizing all his experimentations had gotten him nowhere. Upon his supposed death, which instead erased the majority of his memory and sent him to the Dark Meridian, one of the last things he would hear would be Xemnas's accusations that he was the source of all Heartless, and that the chaos and turmoil that had resulted over the past years were all his fault.

The Seven of Pure Light
Supposedly, seven maidens existed with hearts of pure light, whose hearts when joined as one could unlock Kingdom Hearts. It was for this reason that the maidens, called Princesses of Heart, were sought by beings of the darkness who wished to rule the Heart of all Worlds, particularly Maleficent and Xehanort's Heartless. Kingdom Hearts could only be accessed by the completion of a Keyhole in Hollow Bastion, which required all seven pure hearts to be joined as one in the Keyblade of Peoples' Hearts. These hearts were released, however, due to Sora keeping Kingdom Hearts out of the villains' reach.

Powers and Abilities
A cherished element throughout the Kingdom Hearts series, hearts possess many unique powers and abilities. It is for this reason that antagonists seek them. Hearts are able to produce emotion, something that members of Organization XIII crave. Strong hearts are also able to feel the emotions of those connected with them, demonstrated many times by Sora, who has unconsciously felt the sadness of Roxas, Ventus, and Xion, as well as Vanitas, who was able to feel some of what Ventus felt. As shown with Kairi and Ventus, if one's body remains intact when the heart is lost, and is not turned into a Nobody, the person will enter a state similar to catatonia until the heart is restored. Ventus, in particular, has been in this state for over a decade, without a change in his health, despite there being no one to look after him. It is unclear if he has aged.

Hearts are also able to merge with others or be split, as seen when both Xehanort and Eraqus join hearts with Terra, and when Ventus's heart merges with Sora's. A much later instance of this would be Kairi's heart merging with Sora's during his first journey. They can be split to produce an embodiment of either the light or the darkness, as seen when Master Xehanort produces Vanitas by unlocking the darkness of Ventus's heart. Hearts can also be merged to create unique Keyblades, major examples being the χ-blade and the Keyblade of People's Hearts. These Keyblades ultimately grant access to the grandest of hearts: Kingdom Hearts.

The heart also has a heavy influence on all that lives, having the power to produce Heartless and potentially Nobodies at its loss or corruption by darkness. As the heart grants emotion, negative emotions formed when Vanitas and Ventus were split caused the Unversed to spawn, hence their connection to the heart.

Hearts removed from their bodies, but not transformed into heartless, lose some of the limitations of a physical form. In addition to being able to enter other peoples' bodies, they can move through time itself, as long as a version of themselves is there to greet them, as revealed in Kingdom Hearts Dream Drop Distance. In the original Kingdom Hearts, some disembodied hearts manage to escape the destruction of their worlds, becoming Summon Gems. Through the magic of the Fairy Godmother, Sora is able to use them as summons--temporarily giving them form, so that they may fight by his side. They do this through their own will and are fully conscious of themselves, as revealed when Simba and Mushu remember their adventures with Sora in Kingdom Hearts II. Finally, Ventus's and Terra's Keyblades, presumably directed by their hearts, rescued Aqua at one point in the Realm of Darkness, while Ventus's heart eventually resurfaced inside of Sora's to protect him from being corrupted by a Nightmare Dream Eater.

Magic is able to enhance the powers of a heart. In addition to the Fairy Godmother's ability to empower Summon Gems, Aqua created the Wayfinders, which allowed the user to temporarily gain power and abilities from the hearts connected with them. She also cast a similar spell on Kairi, which would lead her to someone who could protect her if she was ever in danger.

Newly born hearts have even stranger, more unique abilities. Sora's was able to seek out and unite with the broken fragments of Ventus's simply because Ventus was brought to Sora's homeworld. As a result of this, Vanitas took on an appearance similar to Sora's, and Sora's Nobody would later take on Ventus' appearance. The merge stabilized Ventus's heart, allowing him to eventually recover. Xemnas and Xigbar also revealed that a new heart could be "nurtured," even to the point where it became an exact replica of another person's heart, although they implied that they needed the power of Kingdom Hearts in order to do so.

When Hearts are Broken
Naturally, when such an important object is damaged, the effects are catastrophic. The most obvious example is when the heart gives in to darkness, becoming a Heartless. Hearts either become trapped in monstrous shells, as in the case of Emblem Heartless, or physically shattered and rearranged to create those monsters, as with Pureblood Heartless. In both cases, the transformation is usually so extreme that the victim loses his or her sense of self, and if they are restored, they have no memory of their Heartless state.

Even after Sora was restored as a complete being, his corruption continued to plague him. The darkness in his heart would sometimes take over his Drive forms, causing him to transform into the feral anti-form. Although he showed no signs of the usual heartless behavior in this state, it was still a danger, because he couldn't heal or wield the Keyblade while in this form, and could not willingly change back. His Heartless remained alive inside of his memories, corrupting the journal that recorded his journey, growing exponentially more powerful, and attempting to reclaim his body.

A disembodied heart that is not turned into a heartless may sink into a semiconscious state, as with Kairi, who was unable to interact with the world, except to appear as visions to Sora.

When Master Xehanort divided Ventus's heart, Ventus was left catatonic. The last remnants of his heart fading away, he would have died, had Sora not combined hearts with him. Even after this, it took an unspecified but lengthy amount of time for Ventus to return to a sense of normalcy. During this time, if one attempted to interact with Ventus for more than just basic greetings or instructions, he would scream in pain and collapse. Ventus did not regain his memory of what happened to him until Master Xehanort explained it to him. In the novelization of Birth By Sleep, Vanitas also suffers extensively from feelings of incompleteness and inadequacy. After Ventus defeated Vanitas, Vanitas seemingly returned to Ventus's heart, his consciousness vanishing without a trace, while Ventus sank back into catatonia.

Even Master Xehanort suffered some ill effects from messing with his heart. He was not able to completely control Terra's body, and the aftermath of their clash of wills gave him amnesia. Ultimately, he had to give into darkness and become a Heartless in order to get his plans back on track. This heartless was incorporeal, being forced to manipulate events from behind the scenes, and could not use a Keyblade unless controlling the body of another Keyblade wielder. His Nobody inherited his amnesia, and was also unable to wield a Keyblade, for reasons not fully understood. It took Master Xehanort over a decade to regain himself fully.

Kingdom Hearts
Kingdom Hearts is the largest and grandest heart of all. The heart of all worlds, it is a source of fantastic power and wisdom, and as such is sought out by many villains for different reasons. The artificial Kingdom Hearts of Kingdom Hearts II takes on the shape of a heart shaped moon, which further reinforces the fact it is the heart of all worlds. Upon a heart's release after the defeat of an Emblem Heartless, these hearts travel to Kingdom Hearts, empowering it, and in the case of the Kingdom Hearts II storyline, benefiting the Nobodies. However, when you defeat a Pureblood Heartless no heart appears.

Heartless
When a being, be they good or evil, gives in to the darkness in their heart, their heart is consumed by it and becomes a Heartless. This new entity separates from the body and soul, which fade into darkness, and begins to act on a primal instinct to gather other hearts and corrupt them. This instinct results in Heartless attacking other beings to increase their numbers, and attacking the heart of a world by means of the Keyhole, causing it to be completely overwhelmed by darkness. Of course, as dictated by their instinct, the Heartless seek out the biggest heart of all: Kingdom Hearts.

Emblem Heartless defeated by the Keyblade give up the stolen heart, which causes it to return to the owner's original body. However, in Kingdom Hearts II, the hearts went to Organization XIII, which may mean there is a way to change the flow of hearts. Hearts will also not return to their owner if a Nobody was formed.The amount of darkness in the heart, as well as the strength of the heart, seems to dictate the strength of the Heartless formed (as the Princesses of Heart contained no darkness in their hearts, they could not create Heartless. Likewise, Sora's heart contained so little darkness, his became a small Shadow, though his heart was immensely strong. This let him keep his emotions and memories instead of fading to the darkness.) The Heartless are arranged in a hierarchical society, with the most powerful Heartless directing the others' actions. This theory was proven by Xehanort whose Heartless went on to control all others.

Nobodies
When a particularly strong heart is turned into a Heartless, the body it leaves behind begins to act of its own accord due to the strong will it possesses, becoming a Nobody. The body of a Nobody may be warped to a degree from its original form, depending on the strength of its heart. Members of Organization XIII all possessed remarkably strong hearts, allowing their Nobodies to retain their human appearance with only minor changes. Due to a lack of a heart, a Nobody cannot truly feel emotions; many members of Organization XIII often pretend that they can, following their memories of their human selves.

Although Nobodies are born as empty shells, they are capable of developing hearts of their own over time. Additionally, the shells can be implanted with the heart of another, becoming a vessel for that heart.

Heart Collection
In Kingdom Hearts 358/2 Days, Organization XIII's heart collection process was greatly elaborated. While on several missions to various worlds, Nobodies of the Organization would seek out as many Emblem Heartless as possible, obtaining a captive heart from those they defeated. The captive hearts would then be absorbed by Kingdom Hearts, more specifically, Xemnas's synthetic incarnation of the world, immediately afterwards. Organization XIII completely ignored Pureblood Heartless, as they lacked the hearts they sought. The heart collection field was strictly where Xemnas found a use for Roxas, Sora's Nobody being the only one amongst their ranks able to actually release hearts, as he wielded the Keyblade (any other Organization member simply caused a Heartless to fade back into darkness when it was defeated, without the released heart side-effect). Xion also possessed this power, as she was Sora, and to a lesser extent, Roxas's replica. While Xemnas planned on having Xion absorb Roxas so he could have the full power of Sora's Keyblade in the end, he desperately wished to reclaim Roxas after Xion was defeated when Sora's Nobody fled the Organization. He did not count on Roxas being captured by Riku in the Nobody's attempt to free Kingdom Hearts so he could revitalize Xion. This forced Xemnas to use Sora himself as an alternative.

In Kingdom Hearts II, Organization XIII switched tactics and used Sora for heart collection, because no surviving member was able to collect hearts after Roxas was absorbed by Sora. Sora remained unaware of his role in Xemnas's plan, sending captive hearts to Kingdom Hearts as he saved each world from the Heartless threat. When Saïx revealed this role to the Keyblade wielder, however, Sora became wary of defeating Heartless, as he did not wish to aid his enemies, the Organization. He had no choice, however, eventually reaching The World That Never Was, Organization XIII's stronghold. When King Mickey met up with Ansem the Wise, the elderly scholar attempted to encode Kingdom Hearts as data with a special device, the Kingdom Hearts Encoder. He realized, upon the machine's self-destruction, that hearts couldn't be encoded as data, destroying Xemnas's synthetic Kingdom Hearts and releasing every heart it held inside before not only his death, but the final battle in Kingdom Hearts itself between Sora, Riku and the Organization's Superior.

It is unknown what became of hearts released in Kingdom Hearts. While Organization XIII did exist, they did not collect hearts until Roxas's birth, after the events of Hollow Bastion, and after he trained with the Organization members featured in Kingdom Hearts: Chain of Memories. It is most logical that these hearts went back to their bodies and returned to their original form.

Although the Emblem Heartless in Castle Oblivion release hearts, they are merely creations of Sora and Riku's memories. Nearly all of the Heartless that appear within are even copies of Heartless the two had seen in their earlier journey.

Unversed
Unlike other enemies seen throughout the Kingdom Hearts series, the Unversed lack a direct connection to the heart. Instead, they are the embodiment of negative emotions, produced when Ventus's heart was split in half by Master Xehanort to create Vanitas.

Keyblade
Currently, the only known requirements to wield a Keyblade are having a memory of wielding a Keyblade and possessing a strong heart, whether it be a heart of darkness or light. This connection is expected to be further expanded on in the series. A type of Keyblade made from hearts also exists. The only known Keyblades of this type are the χ-blade, which is made from a heart of pure darkness and a heart of pure light, and the Keyblade of People's Hearts, which is made from the hearts of the seven Princesses of Heart.

Body
The body (肉体 nikutai) is a recurring factor and philosophy in the Kingdom Hearts series; along with the heart and soul, it is a part vital to the complete existence of any living thing. The body gives the heart and soul a vessel, granting a person a physical appearance and a form. The body is a medium for a person's heart and feelings to be expressed in the physical world.

The Heart controls the body, much like the brain in the real world, so when someone becomes a Heartless, and their heart is released, they leave behind their body and soul, which is an empty shell and usually withers away. However, if that person's heart was strong enough, the soul will take control of the body and the shell will start to act on its own. A body being controlled by a soul with no heart is a Nobody. While the Heart is the deciding factor as to if a person can wield the Keyblade, the body can be used in a loophole for acquiring the Keyblade, as seen with Ansem, Seeker of Darkness and Riku in Kingdom Hearts. Ansem possessed Riku's body, thereby controlling the heart and giving him access to Riku's Keyblade-wielding powers.

Soul
The soul (魂 tamashii), along with the body and heart, is a part vital to the complete existence of any living thing. The soul literally gives the body life, and is the difference between being alive or dead. It is the force that wills the body to live, and drives it to survive.

When someone becomes a Heartless, their heart, which controls the body, is released and the body and soul is left behind. Usually, the body and soul, having no guidance, wither away. However, if that person's will was strong enough, the soul will take command of the body and will it on as a Nobody. Exceptionally strong Nobodies, such as the members of Organization XIII, retain their human form. Therefore, it is clear that will is related and is an essential part of the soul.

Unlike the heart, which controls the body, telling it what to do and giving it feelings and emotion, the soul is the energy and life the body uses to carry out the heart's commands. Essentially, the soul is life. Therefore, it is assumed that the soul is the spirit or ghost that leaves the body upon death. If the soul leaves the body, it has no energy or drive to carry out the heart's orders, which ultimately causes the being to die.

When the will is exceptionally strong, the soul can live without both the heart and body, as was the case of Terra's Lingering Will; a suit of Keyblade Armor made animate by Terra's disembodied soul.

Epic Mickey series
A Heart is a major plot point in Epic Mickey. Any cartoon character who is loved by many has a heart of their own. All cartoon characters who have a heart reside in the Toon World. Otherwise, once forgotten or retired, they are sent to The Wasteland and their heart disappears. The game's novelization states that people who lack Hearts feel hollow, abandoned and empty (similar to the Nobodies of Kingdom Hearts). Mickey Mouse has the most powerful heart of all, and the villains of Wasteland (by far mostly the Shadow Blot) want to use it to escape their imprisonment.

In the first game, The Mad Doctor attempts to extract Mickey's heart at the beginning of the game to help the fake Shadow Blot escape Wasteland, but fails.

Near the end of the game, after Mickey has redeemed or defeated the fake Shadow Blot, the real Shadow Blot is accidentally unleashed from the Jug on Mickeyjunk Mountain, who then holds Gremlin Gus and Oswald hostage, and will release them if Mickey gives up his own heart. The deed is done, unfortunately, and now the trio must defeat the Shadow Blot from the inside.

Once Mickey destroys all the Bloticles inside the Blot, his heart is released, only for Oswald to grab it. After realizing that Mickey deserves it more than him, Oswald allows it to go back inside of Mickey's body, before unleashing a barrage of fireworks to destroy the Blot once and for all.

In Epic Mickey 2: The Power of Two, the Mad Doctor plans to become famous again by creating an artificial heart through the toons. Utilizing a television transmitter similar to the one Gus constructs in the opening of the game, the Mad Doctor broadcasts his own television show to the Cartoon World, "The Wonderful World of Evil", and is hoping the ratings there will give him a heart again. To become a Toon once more, he pumps the Guardians from the ground beneath Wasteland in an effort to try and harness their power and get revenge on Wasteland by leaving it in an inert state (his machines were the cause of the surge in quake activity). And with the Brush, he would move to the top of the Disney Villain hierarchy. However, he defeated by the efforts of Mickey and Oswald.

Once Upon a Time
"Now, it belongs to me. You see, when you take a heart, it becomes enchanted. Stronger than a normal heart. You're not hurting the beast. You're controlling it.''""

- Rumplestiltskin to Regina

A heart, or an Enchanted Heart, is a magical item featured on ABC's Once Upon a Time. It first appears in the seventh episode of the first season.

Before the Curse
Rumplestiltskin, a powerful magic user, has a debt to settle with the pirate Killian Jones after the latter "stole" his wife Milah many years ago. However, Rumplestiltskin remains unaware Milah willingly ran away with the pirate until he tracks down Jones again. On board Killian Jones' pirate ship, Rumplestiltskin confronts Milah about leaving their son Baelfire. She admits she is the coward, and that she let her misery cloud her judgment. He asks why she was so miserable and she states, “I never loved you!" In his anger, he rips out her heart and crushes it, killing her instantly.

After Cora, the daughter of a miller, rises to power, she asks Rumplestiltskin to teach her how to rip out the King's heart, as a sort of revenge. When she meets with him, King Xavier teaches her "love is weakness". This prompts Cora to rip out her own heart instead, so she can avoid the heart break of leaving Rumplestiltskin for her future husband, the prince.

Many years later, Cora's daughter, Regina, falls deeply in love with a stable boy, Daniel. One night, they plan to run away together, but her mother catches them just as they are leaving. After a small struggle, Cora seems to understand the love Regina has for him. Cora and Regina reconcile, and make up with a hug. Cora embraces Daniel afterwards and speaks a few words of her own wisdom concerning how a parent always wants what is best for their child. Seconds after these words, she rips out his heart and crushes it; killing him. Regina is devastated and is forced into an arranged marriage to King Leopold.

Shortly following Regina's marriage to King Leopold, Rumplestiltskin teaches her how to rip a living creature's heart; with the victim being a black unicorn. Seeing it as a terrible reminder of how her mother ripped out Daniel's heart, she refuses to follow through with his methods, so Rumplestiltskin tears out the unicorn's heart himself. After the failed resurrection of Daniel by a scientist, Regina comes back to Rumplestiltskin a changed woman. She interrupts Rumplestiltskin and his new apprentice and rips out her heart to prove she deserves to be taught the dark arts.

After the death of her husband, the Evil Queen's guards capture the Huntsman. The Evil Queen wishes him to help her kill Snow White, the deceased King Leopold's daughter. She promises him large rewards in exchange. The Huntsman cares for naught except the protection of the wolves, which the Evil Queen promises, and so he accepts the job.

The Huntsman disguises himself as a guard to gain Snow White's trust, but she sees through his facade. Snow White manages to get away from him, but only for enough time to write a last letter to her stepmother. She gives it to the Huntsman, who is overcome with emotion upon reading it. He decides to let her go instead and takes the heart of a deer as a replacement for the Queen.

The Huntsman delivers the deer heart to the Queen. In the chamber of hearts, she holds the heart up, but none of the containers open. The Queen realizes it is not Snow White's heart she holds in her hands. Furious, the Queen turns on the Huntsman and takes his heart as payment. She declares he is hers now, and if he ever crosses her again, all she has to do is squeeze.

As the Evil Queen needed the heart of the thing she loved most for the dark curse to work, she ripped her father's heart out as the sacrifice.

During the Curse
After the successful activation of the curse, the Evil Queen's counterpart, Regina, rules the town of Storybrooke and its inhabitants. After two outsiders, Kurt and Owen, wander in, she befriends them and warms up to the idea of them staying permanently. When Kurt rejects the idea, Regina becomes desperate to stall their leaving. Still having the Huntsman's heart in her possession, she orders his counterpart, Sheriff Graham, to prevent them from leaving town by arresting Kurt for the charges of drunk driving. However, Kurt accidentally witnesses this and attempts to make a speedy escape with his son. He is apprehended at the town border and willingly allows himself to be taken so Owen can flee.

Emma, the daughter of Snow White and Prince Charming, has come to Storybrooke after 28 years. Not knowing the magic she possesses, it is triggered when Sheriff Graham kisses her and he has flashbacks of his life in the Enchanted Forest. Graham becomes convinced he lost his heart, and begs Emma to help him look for it. Regina gains insight that Graham is beginning to regain some memories of his life as the Huntsman in the Enchanted Forest. After he turns against Regina, and she, having no further use for him now that he is not loyal to her anymore, takes his heart and squeezes it to dust. The result is Graham dies of a "sudden heart attack".

After the Curse
While Emma, Mary Margaret, Aurora and Mulan are away searching for a way to Storybrooke from the Enchanted Forest, Cora attacks the safe haven survivors and takes their hearts. She uses the hearts to command the corpses to rise. Several of the dead bodies head off into the forest to ambush the foursome.

In the midst of the corpse ambush, Aurora is kidnapped and taken as Cora's prisoner. Unwilling to give up information to Cora, she is knocked out. While she is unconscious, Cora's accomplice, Hook, sneaks in and takes out Aurora's heart without her knowledge. She awakens to see him standing over her. Though her guard is up, Hook informs her that he is helping her escape to foil Cora's plans. Aurora does not believe him at first, but Hook sticks to his story and asks her to pass the message along to Emma that she should have trusted him. Aurora thanks him and runs from the dungeon. Later, she meets up with her companions in the woods just as Mary Margaret is about to slice Mulan's throat open. Aurora orders her to stop, and helps Mulan up. Aurora tells them how she escaped, what Hook said, and asks what they will be doing next. Unbeknownst to the group, everything she is saying is via Cora's manipulation now that Aurora's heart is in her hands.

Emma, Mary Margaret, Aurora, and Mulan journey to Rumplestiltskin's old cell to look for the ink they need to defeat Cora. They find the jar of ink empty. Suddenly, compelled by Cora's grasp, Aurora throws a rock at a lever, trapping herself, Mary Margaret, Mulan, and Emma inside Rumplestiltskin's cell. When they find the parchment with the ink written on it and use it to escape, Aurora feels Cora's power over her is too dangerous, so she asks to be tied up and left behind.

In the middle of the battle at Lake Nostos, a satchel containing Aurora's heart nearly falls into the portal but is saved by Hook. With Cora and Hook being defeated, and Emma and Mary Margaret making their return to Storybrooke, Mulan takes the heart back to the dungeon and places it back into Aurora's chest.

When David and Mary Margaret discover that the Dark One's Dagger is hidden on the minute hand of the clock tower, they race to grab it first before it falls into Cora's clutches. Just as the two prepare to leave with the dagger, Cora and Regina teleport into the clock tower with Mary Margaret's beloved servant from the Enchanted Forest, Johanna. To compel Mary Margaret in handing over the dagger, Regina takes out Johanna's heart and begins to squeeze it and the life out of Johanna. Unable to watch an innocent life be vanquished in front of her, Mary Margaret surrenders the dagger. Satisfied, Regina places the heart back into Johanna's chest. Relieved, Johanna begins to run towards Mary Margaret's waiting embrace, but Cora cuts off the reunion by flinging Johanna out the clock tower's face and killing her.

In Neverland, Mr. Gold confronts Tamara, who apologizes for shooting Neal. However, Mr. Gold does not forgive her and instead rips out her heart before crushing it to dust.

To settle a long-standing grudge, Tinker Bell kidnaps Regina and threatens to poison her with Dreamshade. Regina offers up her own heart and lets Tinker Bell decide what to do with it. Instead, Tinker Bell explodes in anger over their past history and demands answers, to which Regina finally admits the truth. She tries to deter Tinker Bell from the path of vengeance and choose light over darkness. Eventually, Tinker Bell listens and hands back the heart to Regina.

Pan, who is losing his immorality, tricks Henry into believing Neverland's weakening magic will have a direct impact on everyone else. To "save" magic, Henry must give up his own heart, which will result in death. In actuality, Pan needs Henry's heart to regain his immortality by absorbing all the magic in Neverland. Despite Emma, Neal and Regina's attempts to prove that Pan is lying to him, Henry goes through with the sacrifice and dies.

Effects

Yu-Gi-Oh! series
A Heart is a source of the spirits in Yu-Gi-Oh! Because the same as Kingdom Hearts, if one's body remains intact when the heart is lost, the person will enter a state similar to catatonia until the heart is restored. Hearts are also able to merge with others or be split, as seen when Yami Yugi's heart merges with Yugi's. A much later instance of this would be Marik's heart merging with Téa's, since Yami Marik took over his body, and he controls her.

In the Virtual World arc, the hearts are a keys to the soul room and bodies are a locks: If the statue is destroyed and not repaired, the victim will die due to severing of body parts, his/her heart was released. Tristan's heart was released after Danny broke him while he was turned into a statue. Doing the same on everyone, Chris sacrifices Yugi's friends with Shining Nova effect of "Blue-Eyes Shining Dragon" to release their hearts. Chuck recreates everyone with his People Recreation Program and Chris allows the hearts to return inside of his friends' bodies, regaining their conscious.

Sonic X series
A Heart also appears in Sonic X. Dr. Eggman researched that Yugi's friends have the pure hearts.

All seven hearts together have same colors as the Rainbow Crystals from Sailor Moon.
 * Red Heart: Duke Devlin
 * Orange Heart: Tristan Taylor
 * Yellow Heart: Serenity Wheeler
 * Green Heart: Joey Wheeler
 * Blue Heart: Téa Gardner
 * Indigo Heart: Ryo Bakura
 * Purple Heart: Mai Valentine

Dragon Ball series
A Heart appears in three Dragon Ball series.

Sailor Moon series
A Heart is a major plot point in Sailor Moon. This heart appears same as Epic Mickey. In the wrong hands, a heart can be a deadly weapon as well as very dangerous and life threatening. It is revealed that Queen Serenity passed away when her heart disappears. According to the moon cat Luna, Sailor Moon has the most powerful heart of all and Hexxus, the ancient evil spirit of destruction, wants to use it to destroy all of FernGully.

In FernGully: The Last Rainforest, Professor Norton Nimnul attempts to extract Sailor Moon's heart for the world domination, but foiled by the Rescue Rangers. Hexxus has been released from the tree by the leveler, who then holds Sailor Mercury, Sailor Mars, Sailor Jupiter and Sailor Venus hostage, and will release them if Sailor Moon gives up her own heart. The deed is done, unfortunately, and now Sailor Moon, Tuxedo Mask, the Rescue Rangers and the Sailor Senshi must defeat Hexxus from the inside.

Once Sailor Moon destroys the black vessels with her Moon Tiara Action inside Hexxus, her heart is released, only for Sailor Mars to catch it. After realizing that Sailor Moon deserves it more than her, Sailor Mars hands it to Sailor Venus, who allows it to go back inside of Sailor Moon's body.

Titan A.E.
A Heart of the Drej Queen, the leader of the Drej, described by Admiral Winfield as "The source of all Drej will" and the main antagonist of Titan A.E.
