Undertale x Male Isaac Reader:

Reader Info:
You once had a normal life, you were once a happy child.

You lived happily with your mother and father atop a hill.

You adored your father very much and he taught you to embrace imagination, he taught you how to narrate and tell stories.

This helped a lot as you were quite the social outcast among your peers.

In school you were often teased and bullied due to how strange you looked.

You had no hair, big black eyes and looked closer to an alien than a human.

but you were fine so long as you and your father could spend time together.

However, things all came crashing down when your mother got into religion.

She became a Christian and took her beliefs to an extreme, to a point where your father couldn't take it.

Her religious fanaticism was too much for your father to take and he left you and your mother.

Without your father your mother sunk further into her religion and it began taking over almost every aspect of your life.

With your father gone and you still being bullied in school you went further and further into your imagination to cope.

You isolated yourself in your room even more and this resulted in you spending less and less time with your mother and this combined with her religious nature and insecurities caused her to become abusive.

She began calling you impure, sinful and even a Demon child.

It hurt hearing your mother say that and occasionally she'd even get physically abusive.

With each passing day it got worse, the toys you and your father used to play with were taken away, the drawings you were proud of were torn down and your mother even took the clothes off your back and locked you inside your room.

She claimed that this was all in order to purify you of sin, like God had told her.

As this went on, you began believing her horrible words.

You saw yourself as impure scum that needed to be cleansed and would spend most of your time crying in the chest in your room.

One day, your mother burst into your room brandishing a knife and yelling about how God had told her to kill you to show her devotion.

You pleaded to her that you'd do your best to change, that you'd be better, but it fell on deaf ears.

Before she could stab you however, a Bible from your room's bookshelf fell on her head knocking her out.

Seizing your chance you jumped out of the window in your room and ran away.

You had enough, it was too much, this world wouldn't accept you.

Your father left, your mother wanted to kill you and you looked too strange for anyone to love.

Back in school, you heard about the hole atop Mt Ebott and apparently there were rumors of it leading to Hell.

So, if you were a Demon in the eyes of God, you figured it'd be best to join the Demons in Hell where you belonged.

Either that or you'd just end up dead once you hit the bottom.

Either of those 2 were better than the Hell you were living right now.

Besides your mother would most likely launch an investigation and if you were found the authorities would return you to her.

Once you reached the top you jumped in without hesitation.

You expected to be met with the cold sensation of death.

Instead you simply fell unconscious upon hitting the bottom in a patch of golden flowers.

Upon waking up you found yourself in a soft bed, the last place you expected to wake up.

You feared you were back in your own home and your mother would burst in and kill you any second.

However, that wasn't the case, this room looked nothing like your own and just as you realized that the door opened and a Goat woman with a freshly baked pie stepped through.

Toriel:

Upon seeing her you immediately screamed, curled up into the corner and cried your eyes out.

You were sure this was a Demon as Goats were associated with the Devil in the Bible and you believed your soul would be taken.

Instead, this goat monster hugged you and whispered gently in your ear to calm you down.

You had no idea how to respond and soon a few other individuals entered.

2 were other Goat Monsters.

Asgore:

Asirel:

The 3rd though...was another human, munching on a chocolate bar.

Chara:

After you calmed down and realized no one was going to hurt you, Toriel explained that both Asriel and Chara found you unconscious and naked.

So they brought you back, though Chara was against it, Asriel managed to persuade her.

That's when you remembered you were naked and got embarrassed.

Toriel then Pointed to a pair of clothes they got so you could cover yourself up.

Toriel left the pie on the table in the room and everyone left so you could get dressed.

Chara did shoot you a glare before she left which intimidated you.

You were confused.

Why were they so kind to you, a complete stranger?

It did feel nice though, a far cry from your mother.

With hesitation you got dressed and stared at the pie Toriel made you and your stomach growled.

You were starving and so you hesitantly took a bite out of it and...you began crying once more.

This time, tears of joy as this was the tastiest thing you ate in a long while.

Your mother would often starve you for days as punishment as "God" had instructed her to do so.

Eventually the family returned and found you crying and Toriel immediately hugged you and you hugger her back.

Toriel asked what was wrong but you simply kept crying.

After you calmed down, you told them how you ended up here and safe to say they were shocked and disgusted by what happened to you.

Even Chara who's look of distrust and disdain immediately shifted to one of sympathetic understanding.

After your explanation Toriel decided then and there to adopt you just like she and her family did with Chara.

This shocked you further and you accepted, and for the first time in a long while you felt truly happy.

So for the rest of that day you got to know everyone in the Dreemurr family.

Toriel was the mother you had always wanted, though she was scary when angry like most women.

Asgore was just a big goofball who did his best to be kind to everyone, a far cry from his strong and intimidating appearance.

Asriel was a nice kid, you and he had a lot in common.

Then there was Chara.

Apparently, you and her had a lot in common too.

She didn't have a good life on the surface either and tried to take her own life by jumping down the hole in Mt Ebott, she was found by Asriel and adopted by the Dreemurr family.

You then understood why Chara was so hostile towards you at first, she disliked humans for how she was treated...something you could understand completely.

As the day went by and you were in your room drawing, something you missed doing under your horrendous mother, Chara entered with 2 chocolate bars and offered you one.

You accepted and then you both talked for the rest of the day growling closer until it was bedtime.

As you went to sleep however, you found yourself in a horrible nightmare reliving all your past trauma.

The kids in school bullying you, the beatings you got from your mom and everything.

You heard nothing but insults and mockery and it became too much and you dropped to your knees crying once more.

Suddenly, it all stopped and a deep Demonic laugh entered your ears.

You opened your eyes and came face to face with this.

A Demon of some kind who seemed to be taking great pleasure in your suffering.

You asked him who he was and why he was doing this.

He simply chuckled and while he didn't give you his name, he did give a reason as to why he was tormenting you.

His reason in his own words were:

"You don't deserve happiness."

Aftet that you were jolted awake by Chara who was extremely worried for you.

It was still night.

She heard screaming and rushed into your room and found you crying.

You immediately hugged her and begged her not to leave.

She nodded and got into bed with you, you didn't have a nightmare for the rest of the night.

From there the Nightmares only happened occasionally, but all it took to calm you down was a hug from Chara and the other Dreemurrs.

You got used to the underground pretty fast and you were finally a happy child again.

You made new friends, had a family and even found love.

You and Chara fell in love and eventually the Nightmares stopped completely since you and she now slept in the same bed every night.

(A/N: Us and Chara are still children so don't even go there.)

It was the life you had always dreamed of.

And for a few years it was perfect.

So of course it had to come crashing down when Chara got sick and died.

As Asriel decided to fulfill her final wish by taking her body to the village she was from and laying it in the golden flowers she loved you fell into a deep depression.

It only got worse when you saw Asriel die and turn to dust upon his return.

This of course caused Asgore to start a war against humanity and Toriel took you and left for the Ruins where you stay to this day.

Unfortunately without Chara Azazel was free to torment you and eventually you sunk deeper and deeper into depression.

You talked less and became more introverted making Toriel worry.

You never even came out to meet the other humans that fell down.

All except one...a girl named Frisk.

Frisk:

This girl reminded you so much of Chara and that drew you to her.

What will happen with her arrival.

Love Interests:

Chara: (our first love interest but she's dead now)

Frisk: (Our current love interest)
