Heartbeat

**Heartbeat** is the General of Affection and the first Jinchuriki of Nine-Tails. She is considered to be the most powerful of the Generals of the Light Kingdom, as well the most unstable. She was released from her stone sleeping when Twilight born and it was her appearance that made Celestia and Luna realize the Light Kingdom were starting to wake up.

## Personality

Heartbeat’s personality, just like her powers, is very unstable. She appears to have multiple personalities that take control over her depending of her mood. During the time she didn't have her star seed, this caracteristic was even more evident, as she was unable to control her own emotions.

If Heartbeat is calm and happy, then she’s childish and innocent, acting like the little filly she appears to be. Not only that, but her own joy can actually spread to others, what, because of her empathy, makes her even happier.

Despite appearing to remain joyful most of the time, she is very quick to anger or sadness, throwing temper tantrums whenever something she doesn't like happens. This temper tantrums of her is the reason why she inspire great fear on some villains or ex-villains, like Discord. When she is angry, Heartbeat is cruel and terrible.This explosive and dark personality is what Heartbeat hid in her at all cost and the reason why most ponies try their best to not upset her.

Underneath all this multiple personalities caused by her explosive emotions, there's what appears to be her real personality that is of somepony very intelligent, tactical and mischievous. In fact, she can be very manipulative, using subversive methods to do that, even taking advantage of others' fear of her explosive emotions, what sometimes can make ponies to get mad at her. She can also be quite rebellious as she tends to ignore Golden Paladin's orders whenever that is of convinience to her, like crossing to sealed realms using her swift nature.

## Skills

Due her position as the General of Affection, Heartbeat is able to sense and control emotions. By doing this, she can control in some way ponies actions, as the actions are moved by emotions and feelings. She can also turn emotions in power or energy that she can use to whatever she wants. This is what makes her very unstable, as she can't only use others' emotions, but she can also use hers. Her empathy also allows her to turn anypony good or evil. Her emphaty can also sense when somepony evil is around, but this can be avoided if the pony use his or her inner light as a layer to cover his or her bad intensions.

Also, because of her empathy, she can also induce powerful illusions using the victims' own emotions and feelings to prevent them from getting out. Their illusions are so powerful that can even affect powerful beings like alicorns and are pratically impossible to get out from unless she allows it or if the pony in question is able to overcome their own emotions.

Because she was Nine-Tails’ Jinchuriki, Heartbeat received an affinity for wind based magic.

One of her most famous powers, aside her empathy, is her extreme speed. With it, she can travel to wherever she wants in a matter of seconds. It’s later revealed that this speed is related to the fact she can combine the wind and light natures to create the swift nature.

She once was the Jinchuriki of Nine-Tails and she should have had the powers that his Jinchuriki has. After getting Kurama's power's other half, she became a jinchuriki again. Unlike most tailed beasts, the Nine-Tails' self in her offered no resistance to cooperating with Heartbeat, granting her immediate access to Nine-Tails Energy Mode, which impressed all spectators. Heartbeat's form was slightly darker with different markings than Star's but otherwise identical in appearance and abilities; she could use energy arms, enter Tailed Beast Mode, create Tailed Beast Bombs, and perform stronger versions of her usual attacks.

She is capable of using healing magic, but only to apply first aids.

Heartbeat is also very skillful in sealing magic. She was able to use a sealing spell to contain the Curse of the Poisoned Heart and, according to her (and confirmed by Golden Paladin), her sealing spells, despite not as effective as Golden's, can last longer.

## Relantionships

### Family

#### The Generals of Order

She loves her brothers and sisters and would do anything for them. However, she seems to be closer with Golden Paladin and Melody. She is the only pony who calls Golden Paladin as "Goldy" and is her confidant and he is the only General that has some control over her, despite she normally is the one to be able to win over any argument they get into. Melody is able to calm her down by singing to her.

Heartbeat sometimes have some little disagreements with Mirror Coat, as they are opposites, with Heartbeat defending emotion and Mirror Coat defending reason. However, they are the ones to share deep secrets that no other General is aware of, like the fact Princess Aurora gave birth to a child she conceived with Sombra.

She also possess some sort of bond with Bright Night as they both worked together to seal and contain the Bermikun Triangle.

It's revealed that she had sensed Star overhearing the conversation and incentivates him to try unsolve the all truth.

In "Reunion", Heartbeat is called by Twilight, Blue and Star Knight who confront her about allowing Kurama to escape Mirror Coat's seal. She confirms it and says she only did that because she knew Twilight and Blue would keep Dusk's existence a secret for as long as she could, despite the fact it was inevitable their secret would last. She claimed that she took a calculated risk that, by the time their secret would come to surface, Star and Kurama would already be friends, what would allow Star to use Golden Paladin's seal to seal the curse.

In "Epilogue - A Brand New Begins?", it's revealed Golden Paladin had grounded Heartbeat after hiding that she had added Kurama's energy to Mirror Coat's seal and also for the prank she pulled on Purple Smoke. Even so, Heartbeat appeared on Dusk's birthday party to give him a birthday party: a necklace with the Eye of Beru. That causes suspition on Star, who knows about Heartbeat's ability in giving gifts. Later, when she returns to the Light Castle, she is confronted by Golden Paladin, who has the same suspitions as Star.

### Adventures in the Bermikun Triangle

In "Prologue", Bright Night visits Heartbeat to confront her about the fact she gave the Eye of Beru to Dusk Storm.

In "Dusk's Choice", Heartbeat and Bright Night appear to Twilight and reassure her that Dusk will be able to save the Bermikun Triangle.

In "A Vortex Away From Home", before Golden Bones can pass the vortex, he is captured by Heartbeat who places him in Tartarus through the prison-book. She then reveals herself to Dusk and the others, much to Calabrass' annoyance. It's revealed that she was the one that created the Chaos, along with Bright Night, being the one responsible to give him life and the ability to produce his antibodies. She then explains that she gave the Eye of Beru to Dusk because she knew he was up to the challenge of opening the Waypoints, that he was the one that could save all the ones imprisoned in the Bermikun Triangle. Heartbeat also reveals being the creator of five of the Waypoint Guardians, including Anpu and Skullivar. After Clover and Mallet return home and Opal and Steam decide to remain in the Bermikun Triangle, Heartbeat, at the others' demands, undoes the curse she placed on Calabrass, despite being unable to undo it completly. When Chaos shows an interest in remaining with Dusk, Heartbeat let the latter keep the former. She then sees as Dusk, Star and Chaos cross the vortex to go home.

### The Elements of Virtue

In "The Element of Bravery, Part III - An Act of True Bravery", Heartbeat is sent by Mirror Coat to take Gunter, Hawthorn and Bramble, and also Flash Magnus, out of the territory of the Mountain Dragons.

In "The Element of Sorcery, Part VII - The Return of the Sorcery", Heartbeat gets into the Mirrored Library, where she justifies to Golden Paladin her absence by saying that Mirror Coat asked her to help Gunter, Bramble and Hawthorn.

In "Breaking the Stone", after the Mane 6 are freed from their stone prison, Heartbeat arrives and reunites with Pinkie Pie, only to reveal that her relief is just to hide her intent to prank her with a buzzer.

### The Cursed Kingdom

In "A Mystery and a Secret", when Heartbeat tries to do an intervention on Golden Paladin when he starts acting out, she ends up slipping about a secret that she and Mirror Coat share together. Intrigued by that, Golden starts pressing Heartbeat about the secret, causing her to run away to the Mirrored Library. There, she has a talk with Mirror Coat about their secret, but they are being eavesdropped by Golden Paladin who is discovered by them before he can know more about it. Confronting the two Generals about their secret, Golden Paladin demands to know about it is, but Mirror Coat responds by saying that each General is entitled to have secrets as they come with their respective jobs, exemplifying by saying Golden himself had secrets. Realizing how he has been acting, Golden Paladin knows he needs to calm down. They then watch as the Tree of Crisis calls upon Star Knight and Bramble for a mission.

In "The Cursed Kingdom", Heartbeat observes as the place where Star and Bramble will be sent by the Tree of Crisis is revealed, with that being Falancia. Once she gets to know it's Falancia, she hastly gets out of the place. Once Star, Bramble and Golden Paladin get out, she is revealed to have not left the library and she and Mirror Coat talk about their secret that may be about to be revealed.
