Yall I’ve gone down an undertale rabbit hole and my like twenty different AU concepts, here are the ones I expanded on and claimed. I needed major help from an ai because I didn’t know what I wanted at first. I later used a lot more of mine and my friends ideas.
The Underground exists in a spectrum of sound frequencies. Monsters are beings of pure sonic energy, and human souls emit unique tonal signatures.
- Protagonist uses a device that converts sound into visible waves
- Each area has its own musical frequency that affects reality
- Combat involves manipulating sound waves
- Monsters can shift between sound and physical form
- **SANS:** The Low Frequency
- Speaks in bass tones that can tear reality
- Can hear across all frequencies
- **PAPYRUS:** The High Frequency
- Voice can create solid light constructs
- Puzzles require perfect pitch to solve
- Battle music literally affects combat
- Sound-based save points that record "sound memories"
- Areas change based on dominant frequencies
- Healing done through harmony
- Different endings based on final symphony created
UNDERTALE: Frequency - Expanded
## The Fallen Humans of Frequency
- Soul Color: Red with sound wave patterns
- Ability: Perfect Pitch - can manipulate fundamental frequencies
- Weapon: Tuning Fork that can shatter or reform reality
- Story: Tried to use sound to break the barrier, became one with the Underground's resonance
### ARIA (Current Protagonist)
- Soul Color: Blue-Green (Sound Harmony)
- Ability: Sound Synthesis - can combine different frequencies
- Weapon: Sonic Amplifier (looks like headphones)
- Special Power: Can "tune" into monster souls
- Each human soul emits a unique frequency
- PATIENCE: Low, steady hum (432 Hz)
- BRAVERY: Sharp, bright tone (528 Hz)
- INTEGRITY: Deep resonance (396 Hz)
- PERSEVERANCE: Complex harmonics (417 Hz)
- KINDNESS: Soft, healing tones (639 Hz)
- JUSTICE: Clear, piercing note (741 Hz)
- Can create "dead zones" of absolute silence
- Gaster Blasters emit sonic booms
- Bones vibrate at skeleton-shattering frequencies
- Special Attack: "The Drop" - complete sonic nullification
- Creates "sound puzzles" requiring perfect pitch
- Bones emit musical notes when dodged correctly
- Special Attack: "Symphony of Bones" - creates a deadly musical score
- Can amplify others' sound powers
- Spears create sonic shockwaves
- Can "tune" into opponent's soul frequency
- Special Attack: "Warrior's Chorus" - multiple frequency spears
- Armor resonates with determination
- Built the Underground's sound manipulation technology
- Studies "lost frequencies" from the surface
- Created the CORE's frequency stabilizers
- Experiments with sound-based determination extraction
1. Each attack has a specific frequency
2. Players must match or counter frequencies
3. Dodging requires understanding sound patterns
4. Healing done through harmonic resonance
- Different areas have different base frequencies
- Waterfall's rushing water creates natural white noise
- Hotland's magma produces low frequency rumbles
- Snowdin's snow dampens all sound
- Frequency Shift: Change attack patterns
- Harmonic Resonance: Combine powers
- Sound Barrier: Block specific frequencies
- Echo Location: Find hidden paths
I did have to explain to my “very” concerned brother that Frequency Sans isn’t as over powered as he thinks he is, his main question was if Sam’s voice is so low that he can ter reality and shadow bones why hasn’t he broken the barrier and my response to that was it’s because that could literally kill him because in order to do that he needs to not only use his voice, but use his voice to at least two gaster blasters for a good 40 to 50 minutes in order to break the barrier because he only has one HP he’ll die at least 15 minutes in.
The Underground is a living story, constantly rewriting itself. Monsters are characters trying to find their "true tale."
- Reality shifts between different genres

UNDERTALE: Anthology - Expanded
## The Story Weavers (Fallen Humans)

### READER (Current Protagonist)

Fights occur in "Story Spaces" where:
1. Combatants take turns writing the narrative
2. Reality shifts based on genre
3. Power comes from story strength
4. Victory achieved through better storytelling
- Write attacks into existence

- Heal through positive character development
- Can break the fourth wall
- Creates plot holes as attacks
- Special Move: "Bad Time" rewrites the entire fight

- Writes heroic epic battles
- Creates dramatic tension
- Transforms through character development
- Special Move: "Heroine's Journey"
- Studies story mechanics
- Experiments with genre fusion
- Created the CORE plot device
- Special Move: "Meta Commentary"
Each area has a dominant genre:
- SNOWDIN: Winter Fantasy
- HOTLAND: Science Fiction
- NEW HOME: Historical Drama
- Rapid narrative changes
- Short, powerful story bursts
- Complex plot development
- Long-term narrative changes
- Reality bends to spoken word
- Requires perfect delivery
- Stories must maintain internal logic
- Genre rules must be followed
- Character development must make sense
- Plot holes weaken reality

- Genre Shift: Complete reality change
- Reality Write: Complete story control
- Plot Twist: Unexpected narrative change
- True Ending: Forces story conclusion
- Character Arc: Complete transformation
- Meta-Narrative: Transcends story bounds
Most of this at points I made to expanded on and repeated back to me I also went into a lot more detail for Undertale Anthology
- It's a fascinating twist that Sans is secretly the true Editor while everyone assumes it's Asriel
- The requirement of collecting fallen human hearts adds a dark undertone to the role
- The heart storage system in books is unique, especially how destroying the books destroys the hearts unless saved in the Editor book
- The first human's transition from pacifist to genocide for unknown reasons adds mystery
- The confrontation with Papyrus trying to use 'The Great Papyrus Chapter' shows how powerful the Editor role can be
- Sans' immediate response to rewrite reality and kill Author demonstrates the stakes

1. Genre Powers Inheritance:
- Each fallen human specialized in different story types
- Their powers combined created the current Underground's genre system
- Reader can access all their abilities through the rainbow soul
- Personal books act as both power source and soul container
- Books can be read to gain temporary access to that human's powers
- Destroying a book releases the soul but risks losing its power forever
- Sans gained different abilities from each human he defeated
- Keeps half the power even after Reader gains their share
- Can rewrite reality but needs the correct "genre" power
If you made it to the props to you! Any feed back is welcomed and thanks for taking the time to read this overly long post
