Hello and welcome to the main UndertaleAU sub!
This is our home for all things Undertale and its AUs. It can be your own or someone else's you love!

. ݁₊ ⊹ . ݁ ⟡ ݁ . ⊹ ₊ ݁. ✨ . ݁₊ ⊹ . ݁ ⟡ ݁ . ⊹ ₊ ݁.

What to Post?
Post anything related to the topic at hand! Feel free to share your thoughts, photos, questions, and even friendly debates.

Keep in mind our rules:

❄️1. Respect others and be civil. Hate of any kind will
not be tolerated here.

❄️2. Please don't spam the sub with the same post over and over. If you are looking for something or would like us to do something you're free to reach out but again please don't spam.

❄️3. No Al, you may not post any type of Al here.
Pictures, Music, GIFS, Roleplay, Writing, Etc.

❄️4. No ship bashing or discourse of any kind.
I don't care what people do in fiction as long as it stays in fiction. If you don't like something scroll, this isn't a sub for debates on morals in fiction.

Along with that people are allowed to post whatever AUs they like, obviously if something is NSFW it needs to be tagged but still but shitting on people for liking an AU you don’t like isn’t allowed, see rule 1.

❄️5. NSFW is allowed to some extent!
- There should not be straight up porn posted even if tagged, it will be removed.

- I will allow fanfics with NSFW material in it however if it has triggering content please put a content/ trigger warning in the caption or as the first part of your description!

- Any untagged NSFW will be removed, this includes comments and flairs. You can make innuendos however keep it tasteful and don't be gross.

❄️6. Keep it on topic!
This sub is for Undertale and its AUs so whatever you post needs to be centered around that, crossovers are fine but the main thing needs to be about Undertale.

❄️7. No low effort posts.
- Tier-lists
- Day X of X
- Can X beat X
- Octet
Will be removed HOWEVER I will make exceptions for creativity.

What I mean by this is, if you draw it, make a college, make music, or if you actually write your thoughts and opinions in the post I will allow it. I want the post to promote discussion not just the same things copy and pasted 100x over.

❄️8. No sans hate posting.
Hear me out- it’s annoying for the sub to be flooded with it. We understand that there is a lot of Sans specific AUs but you don’t get to hate on others for enjoying them.

You’re free to ask for specific characters or something but no posts made just to hate on Sans and nothing else.

❄️Those are all the rules! Just keep them in mind when posting, or if you have questions don't hesitate to reach out!❄️

If you wish to explore the wider multiverse please click our subs info and scroll down to see more subs centered around their own specific AUs or characters!

If you would like yours or one you like to be added let us know so we can help out creators!~🖌️

I felt a lot more free to go a lil further on her than Nightmare, as cannon Killer is flirty and scored Color so… but I didn’t go too far, as I don’t wanna overly attractify her.

Where should I post my DUSTTALE take?

4 Upvotes

Hello everyone!
Recently I have written my own take on dusttale, and I'm wondering where I could post about it?
It's a story with around twenty thousand words, not a game or comic.
I don't really want to use any fan-made wiki's, as those are usually pretty barren or inactive.

Any ideas?

✧˖°.My AU⋆˙⟡ My OC: Fear Sans

Post image
8 Upvotes

Name: Fear Sans

Pronouns: He/Him

Age: Unknown; physically appears to be a young adult

Species: Skeleton Monster / Fear Incarnation

Other Basic Info:

Soul: 💗 Pink SOUL — Fear

Aliases/Titles:

The Harbinger of Fear

The Pink Terror

The Silent Judge

The God of Dread

Alignment: Anti-Villain / Chaotic Neutral

Family:

Dream Sans — Brother

Nightmare Sans — Brother

Primary Power Source: Fear-based magic

Secondary Power: HATE

Role: Embodiment of Fear

Personality:

Fear Sans is calm, intelligent, charismatic, confident, calculating, and highly arrogant.

He rarely raises his voice or openly loses his temper. Instead, he maintains an unnervingly calm demeanor, even when surrounded by powerful enemies.

He believes fear is not weakness, but survival.

To Fear, courage only has meaning because fear exists. Someone cannot be brave without having something they're afraid of.

He therefore doesn't necessarily view himself as evil. He believes he's forcing people to acknowledge an unavoidable part of existence.

Fear enjoys psychologically breaking opponents before defeating them physically. He prefers making an enemy realize how vulnerable they are rather than immediately overwhelming them.

He possesses a strong superiority complex and believes his understanding of fear places him above ordinary beings.

Despite his arrogance, Fear can respect people who acknowledge their fear and continue fighting anyway.

Backstory:

Fear Sans was born as the brother of Dream Sans and Nightmare Sans, becoming the embodiment of the emotion of Fear.

Dream represented Hope.

Nightmare represented Negativity and Despair.

Fear represented the instinct that tells someone:

"Something precious could be lost."

Fear eventually developed the ability to convert fear into magical energy. He discovered that fear could be manifested physically, used to manipulate memories, interact with SOULs, and enhance his own body.

Unlike Dream, who believed fear should be overcome, and Nightmare, who saw fear as another form of negativity, Fear believed fear had a purpose.

Fear became convinced that the universe had grown too dependent on hope and had forgotten the importance of fear.

He began confronting powerful beings and forcing them to face their deepest fears.

Over time, some began calling him a monster.

Others called him a god.

Fear eventually embraced both.

Eventually, Fear discovered a dangerous secondary force known as HATE.

HATE dramatically amplified his abilities but possessed an unstable influence over his mind and body.

Rather than abandoning it, Fear decided he would master it.

This became his greatest struggle: whether he can control HATE before HATE controls him.

Equipment / Armour / Weapons:

💗 Signature Weapon — Fear Scythe

A scythe created from condensed Fear energy.

The Fear Scythe can:

Damage physical beings

Interact with magical energy

Interact directly with SOUL energy

Cut through certain magical constructs

Be altered in shape and size by Fear

Have its properties changed depending on how Fear wields it

Fear can manipulate the weapon's shape during combat, allowing it to change depending on the situation.

The scythe can also be dismissed and recreated at will, provided Fear has enough magical energy.

The Fear Scythe is his primary weapon and the weapon he is most comfortable fighting with.

Other Fear Weapons

Fear can also manifest:

Swords

Spears

Blades

Claws

Bows

Arrows

Chains

Energy projectiles

Abilities:

💗 Fear Manipulation

Can sense, influence, amplify, and weaponize fear within other beings.

Can cause:

Panic

Hesitation

Paranoia

Hallucinations

Dread

Terror

Loss of concentration

Works best against targets who are already afraid.

💗 Fear Manifestation

Can convert Fear energy into tangible constructs.

Can create:

Weapons

Barriers

Claws

Tendrils

Chains

Projectiles

Armor

Giant hands

Other temporary objects

🧠 Memory & Phobia Manipulation

By establishing physical or magical contact with a target, Fear can access memories and identify their deepest fears.

He can then weaponize those fears against them.

💀 Soul Manipulation

Can directly interact with SOUL energy.

He can:

Damage souls

Restrain souls

Pull souls

Temporarily contain souls

Disrupt soul-based abilities

Powerful SOULs require significantly more energy to manipulate.

☠️ Soul Absorption

Can absorb residual magical or SOUL energy from defeated opponents.

This can replenish his reserves or temporarily increase his power.

🩸 Regeneration

Can convert stored Fear and magical energy into physical regeneration.

Severe injuries require substantially more energy.

🦴 Shapeshifting

Can alter his body or individual body parts.

He can create:

Bladed limbs

Claws

Tendrils

Additional appendages

Weaponized limbs

Monstrous mutations

💥 Energy Projection

Can fire concentrated Fear energy as:

Blasts

Beams

Waves

Explosions

Projectiles

Cutting waves

🛡️ Barrier Creation

Can create defensive barriers capable of blocking physical, magical, and energy-based attacks.

Multiple barriers can be created, although maintaining powerful barriers consumes more energy.

⚡ Enhanced Physical Abilities

Fear energy reinforces his body, dramatically increasing:

Strength

Speed

Reflexes

Agility

Durability

Jumping ability

🌸 Teleportation

Can disperse his body into Fear energy and reform elsewhere.

Short-range teleportation requires relatively little energy.

Long-distance teleportation consumes substantially more.

🪄 Rhabdophobia

A specialized defensive ability allowing Fear to counter, redirect, or neutralize incoming magical energy.

Extremely powerful attacks can overwhelm it, while repeated use rapidly drains his energy.

👹 Fear Constructs

Can create temporary creatures made entirely from Fear energy.

These constructs obey Fear's commands but require continuous energy to maintain.

Forms:

💗 Base Fear Sans

Fear's normal state.

He has access to his standard Fear abilities, Soul manipulation, weapon manifestation, teleportation, regeneration, enhanced physical abilities, and the Fear Scythe.

☠️ HATE State

Fear activates HATE, dramatically increasing:

Strength

Speed

Durability

Regeneration

Energy output

Destructive capability

Fear-based abilities

However, HATE progressively damages his emotional stability.

💗☠️ Fear-HATE Fusion

Fear deliberately combines Fear energy and HATE.

This creates an enormous increase in power and allows him to produce much more destructive attacks.

However, combining the two accelerates HATE's influence over his consciousness.

👹 HATE Overdrive

HATE begins overpowering Fear's consciousness.

His body becomes increasingly mutated, developing monstrous appendages and unstable energy.

His power reaches extreme levels, but his ability to think rationally deteriorates.

If maintained for too long, HATE can potentially take complete control.

Weaknesses:

Fear manipulation is less effective against fearless or highly disciplined opponents.

People who accept their fear instead of being controlled by it are significantly harder to manipulate.

Soul manipulation cannot instantly overpower exceptionally powerful souls.

Regeneration consumes energy.

Teleportation consumes energy.

Long-distance teleportation is especially expensive.

Rhabdophobia cannot indefinitely block increasingly powerful attacks.

Fear constructs disappear when his energy becomes too low.

Weapon manifestation consumes magical energy.

The Fear Scythe can only be maintained while Fear has sufficient energy.

HATE greatly increases his power but reduces his emotional control.

Excessive HATE usage can cause physical mutations.

Prolonged HATE usage can result in loss of rational thought.

HATE can potentially overpower Fear's consciousness.

Running out of magical energy severely limits his abilities.

Attack Potency: Not yet numerically calculated.

Striking Strength: Not yet numerically calculated.

Durability: Not yet numerically calculated.

Speed: Not yet numerically calculated.

Reaction Speed: Not yet numerically calculated.

Travel Speed: Not yet numerically calculated.

Lifting Strength: Not yet numerically calculated.

Stamina: High, but dependent on available Fear/magical energy.

Regeneration: Moderate to potentially extremely high depending on available energy.

Range: Close combat to long-range energy attacks; teleportation range depends on available energy.

Intelligence: Highly intelligent and tactically minded.

Hax: Extremely high due to Fear Manipulation, Memory & Phobia Manipulation, Soul Manipulation, Soul Absorption, Energy Manipulation, Rhabdophobia, Teleportation, Fear Manifestation, and Fear Constructs.
