Sapphire/Apprentice to Error

## Backstory

Sapphire is the fifth ~~forgotten~~ human who has fallen after Chara as she is originally from WiseTale. Sapphire during her time in the Underground battles many monsters only injuring them as a last resort however, she soon stumbles upon her family's graveyard seeing their corpses which horrifies Sapphire changing her personality. Sapphire eventually encounters and battles the Mountain King as she becomes cruel and malicious, but in the end she died by his hand and in her final moments she curses the Mountain King before she passed away.

Sapphire is then reincarnated in the universe UNDERFELL now a fully grown adult with different colour clothing. Sapphire is in the Barrier remembering everything in her time in the Underground and this results in her having a thirst for vengeance wanting to inflict pain to monsterkind for what they have done to her family. Sapphire leaves the Barrier heading back to the Ruins where it all started for her.

Sapphire encounters a talking flower begging for his life and at first she comforts the flower before ripping out his petals and stomping on the flower which the flower crumbles to dust. Sapphire travels along the Ruins brutalising every single monster in the Ruins however, she stumbles upon a ghost that tried to kill her. Sapphire tried to kill the ghost as well however, neither are successful as the ghost escaped never to be seen again.

After Sapphire annihilated all the monsters in the Ruins (excluding Toriel/UNDERFELL) she once again stumbles upon Toriel's house, but she quickly leaves looking for other monsters that she can kill. Sapphire journeys around the Underground not finding another monster however, she meets her sister Aqua in Waterfall. Aqua has also been reincarnated as she tells her story to Sapphire meeting skeletons and soon realises that the Mountain King killed their sisters Emerald and Amber as well as their brother Garnet. Aqua then reveals that she died by the hand of the Mountain as Sapphire also tells her story to Aqua battling the Mountain King before she died to him as well.

Aqua and Sapphire walk back to the throne room discussing if their last sibling Violet has survived, but soon they see the Mountain King sleeping on his throne and they hear voices behind them not knowing who they are. Both Sapphire and Aqua hide behind one of the pillars waiting for whoever is coming through that door soon seeing both Garnet and Violet as then they hear more voices behind them as well, so they hid in one of the pillars as well. Amber and Emerald also appears as well as they as well hear voices behind them hiding in one of the pillars and lastly their brother Krotos along with another human arrive as the Mountain King wakes up from his slumber.

Sapphire is happy to see her brother again, but dark thoughts clouds her mind becoming jealous as well as malicious. The Mountain King reveals his whole life story in the Underground which angers Krotos brutally killing him in the process. Sapphire and the rest of the family come out of their hiding spots as Krotos is shocked to see his family again, but Sapphire remembers that their father gives Krotos all of his attention and not hers and she hates them for that. Sapphire could not explain the reason why she feels that way, yet unknown to her Sapphire's Soul is influencing her darkest desires eventually fighting her own brother and then shortly after dying once again, but this by her brother's hand.

## Profile

### **Appearance**

Sapphire wears a lime tutu along with black shoes as well the rest of clothing is lime as well. Sapphire's reincarnation makes her taller having a slim physique however, she keep her black hair and dark blue eyes even after her reincarnation. Sapphire appearance becomes messy after the senseless slaughter in the Ruins as her clothes are covered in dust.

### **Personality**

Sapphire becomes sadistic and malicious after being reincarnated as her savagery spread across the Ruins hurting every monster in her path without empathy. When Sapphire meets Aqua she is then displaying empathy and understanding which ironically makes them better siblings understanding each other's pain however, this would not last as her darkest emotions rise again taking it out on her brother showing no empathy towards him and neither her sister Emerald.

## Soul

Sapphire inherits the Soul of Cruelty a Nightmare Soul created by Nightmare!Sans by corrupting the Kindness Soul into Cruelty. The Soul affects Sapphire making her become more savage and unforgiving giving out cruel punishment to the innocent as well as the sinners alike. This condition would only get worse every second she breathes as the Soul corrupts her and soon no longer caring about her family only wanting to hurt her brother as her father never gave her the attention like he did with Krotos.

## Abilities

**Increased Stamina:** Sapphire has a lot of Stamina since she has been practicing ballet that even surpasses Krotos's and Amber's. Sapphire can battle or practice for an extended period of time which helps her in a lot of situations that she encounters. Sapphire although not as strong as Krotos or Amber uses her stamina to her advantage so she can tire out her opponent.

**Kickboxing:** Sapphire teaches herself kickboxing and at first she was a novice however, Amber helps her out improving her techniques. Amber and Sapphire occasionally spar to help each other in the heat of combat. Sapphire apricates Amber for helping her improve and is no longer a novice on the martial art. Sapphire although not as powerful as Amber is a much better fighter than Garnet something that she is extremely proud of.

**Savagery:** After inheriting the Soul of Cruelty Sapphire becomes more deceptive and sadistic mocking and torturing her opponents in vile manners. Sapphire has been successful in mentally breaking down her opponent using their worst fears against them however, this ability can only work against monsters or humans with uncorrupted Souls.

## Weaknesses

**Obsessive:** Sapphire's Soul makes her obsessed into killing whoever is put in her way however, this could potentially lead to her downfall going against opponents that clearly outmatch her, but her stubbornness will not let her give up. Sapphire's obsession ruins her mentally becoming a husk of what she once was before she abandoned her morals.

**Stubborn:** Sapphire is quite stubborn believing that she can do everything by herself although some tasks are out of her depth. Sapphire hates to admit asking for help, but she will express gratitude towards others regardless.

**The Soul of Cruelty:** Although Sapphire uses savagery to her advantage it is also a double edged sword as it corrupts her own mind feeding off her darkest desires to inflict pain towards others leaving a lasting affect. Sapphire enjoys inflicting pain onto others no longer caring who she hurts, but if she is up against another Nightmare Soul this would actually diminish her chances of survival. If her opponent has a Nightmare Soul she cannot harm them to the extent that she could do to others and in some cases could even boost their own Nightmare Soul's power which could result in devastating consequences.

## Relationships

### **Flowey the Flower/UNDERFELL (Enemies)**

Flowey or formerly known as Asriel Dreemurr is a talking flower scared for it's life against the savage monsters in the Ruins. Flowey is scared of one particular monster though which is Toriel however, one day he meets a female human wearing a lime tutu. Sapphire looks down upon the flower with insidious intent as Flowey is begging for his life. Sapphire smiles and places a hand on one of his petals then ripping it out then stomps on Flowey resulting in him turning to dust. Sapphire smiles devilishly as she walked away happy that she could inflict pain, but the only thing she didn't know is that she is being watched.

### **Napstablook/UNDERFELL (Enemies)**

Napstablook a talking ghost is woken up by a human adult and is annoyed by them, so he decides to start battle with them. Sapphire tries to harm the ghost however, she phases right through him while not inflicting any damage towards him. Napstablook tried to take advantage of the situation, but Sapphire is extremely agile resulting her in fleeing the fight. Napstablook annoyed that he did not get to kill the human decided to nap somewhere else where nobody would find him.

### **Aqua/Apprentice to Error (Sisters)**

Aqua surprisingly finds Sapphire in Waterfall dicussing their pasts in the Underground and what has happened to their family. Although Aqua and Sapphire did not get along back in the past due to their difference, but now they become closer then they ever were before since they know each other's pain. In the throne room where everyone hide in the pillars and after witnessing the death of both the Mounatin King and Emerald both Aqua as well as Sapphire become unempathetic. They no longer shared concern for each other and wanted their brother dead, but to their ignorance their Nightmare Souls extremly influenced by their darker leaving common sense behind.

### **Krotos/Apprentice to Error (Brother)**

Krotos at first is delighted to see Sapphire alive and well including Sapphire herself however, when Emerald dies by Garnet's hand everything changes. Sapphire becomes taunting and being spiteful towards Krotos as he looks back with disbelief holding Emerald in his arms. Krotos is angered by Sapphire's comments, but is soon attacked by his sister. Sapphire tried to injury Krotos however, instead Krotos grabs and breaks her leg leaving Sapphire helpless on the floor. Sapphire and Krotos no longer love each other as they see each other as enemies and nothing more.
