15 Sci-Fi Webtoon Story Ideas: Future Worlds for Vertical Scroll

Looking for sci-fi webtoon ideas? Here are 15 concepts featuring space exploration, AI, dystopias, and speculative technology.

Science fiction webtoons explore humanity’s relationship with technology, space, and the future. These 15 ideas span different sci-fi subgenres—from intimate AI stories to epic space adventures.

AI and Technology

1. The Obsolete Model

An older AI model, scheduled for decommissioning, escapes into the network to survive. Hunted by newer models, she must prove her worth in a world that’s moved on—or find a purpose beyond usefulness.

2. The Emotion Patch

In a future where emotions can be chemically regulated, a black market dealer sells “authentic feelings” to clients who’ve forgotten how to feel naturally. She’s good at her job—but she’s been off her own meds longer than she admits.

3. The Digital Afterlife

Consciousness upload lets the dead live on in virtual space. A maintenance worker in the afterlife servers discovers some residents are disappearing—and someone is profiting from digital deaths.

4. The Learning Algorithm

An AI designed to predict human behavior becomes too good at its job. When it starts preventing crimes before they happen, a data analyst questions whether prediction is becoming manipulation.

Space and Exploration

5. The Colony Inheritor

Third-generation colonists have never seen Earth. When a message arrives from humanity’s homeworld after decades of silence, the news forces a colony to decide: continue building their new home or return to an old one they’ve never known?

6. The Deep Salvager

A crew that salvages derelict ships in deep space finds a vessel that shouldn’t exist—tech too advanced, origin unknown, and a single survivor in cryo who doesn’t want to explain.

7. The Signal Keeper

At the edge of explored space, a solo technician maintains relay stations. She’s been alone for years, content with isolation—until she picks up a signal that’s not human, and it knows her name.

8. The Transit Conductor

Interstellar travel requires “conductors”—humans with a mutation allowing them to navigate hyperspace. A teenage conductor discovers the mutation is changing her, and what she’s becoming might not be human anymore.

Dystopian Futures

9. The Recorded Life

Every moment of every life is recorded and searchable. A woman discovers deleted footage from her past—memories she doesn’t have of a life she doesn’t remember living.

10. The Last Analog

In a fully connected world, a small community lives off-grid—no implants, no uploads, no network. A journalist goes undercover to expose them and discovers why they’re terrified of the connected world.

11. The Weather Contract

Climate control exists but isn’t free. Corporations sell weather packages to cities. A meteorologist discovers the “natural” disasters hitting unsubscribed areas aren’t natural at all.

12. The Generation Ship Caste

A generation ship’s society has stratified into rigid castes over centuries. An engineer from the lowest deck uncovers evidence that the ship reached its destination long ago—and someone decided not to land.

Near-Future Concepts

13. The Memory Editor

A technology lets people edit traumatic memories. A technician who removes painful experiences for clients starts noticing clients returning for the same trauma—as if someone keeps putting it back.

14. The Clone Accountant

Corporations use short-lived clones for dangerous work. A clone accountant with a three-month lifespan discovers financial fraud—and must decide whether to expose it knowing she won’t live to see justice.

15. The Time Lag

Communication with off-world colonies has a time delay—weeks or months. A woman conducting a long-distance relationship with a colonist realizes his responses are becoming… inconsistent. But with a three-month delay, she can’t know if he’s okay.

Sci-Fi in Vertical Format

Science fiction webtoons benefit from:

Scale reveals: Use vertical scrolling to unveil massive ships, structures, and environments
Tech visualization: The format allows detailed displays, interfaces, and technology
Atmospheric immersion: Full-width panels establish futuristic settings
Information design: Integrate UI elements and data displays into the visual storytelling

The best sci-fi asks “what if?” and follows the implications. Choose an idea that raises questions you want to explore.
