For centuries, two kingdoms have ruled humanity.

Near each capital stands an ancient tree.

One shines like living light.

The other is rotten from within.

Both trees speak.

And now two young men carry relics that should have never awakened beneath the roots.

I’ve been working on a Kryptonian OC named Migalex — not related to Superman, just an average kid who actually grew up on Krypton before its destruction.

In this version of Krypton, society is hyper-efficient but emotionally distant. Children are judged by usefulness, military/scientific authority dominates everything, and the government slowly hides Krypton’s instability behind patriotic messaging.

After Krypton dies, Migalex reaches Earth and begins developing powers under a yellow sun:

sensory overload from super hearing,

accidental destruction from super strength,

unstable flight,

heat vision,

and the horrifying realization that Kryptonians were basically “biological gods.”

What disturbs him most is this:

If Krypton was an interplanetary civilization… statistically they should’ve discovered yellow suns long ago.

So why was it hidden?

Unlike Superman, Migalex values stability and control over freedom because he watched Krypton collapse in silence.

Would a Kryptonian like this feel believable in Superman lore?

What if the human heart evolved into a living plasma reactor?

The GG Mutation is a rare hereditary anomaly where a mutated organ inside the heart converts matter into plasma energy, enhancing the human body beyond normal limits. Every carrier manifests the mutation differently depending on their biology and psychology: heat vision, explosive energy release, extreme speed, flight, regeneration, and more.

But the system has limits.

The plasma is not infinite, not perfectly efficient, and prolonged use causes physical stress, pain, exhaustion, and cellular overload. Users must constantly consume energy through food, and pushing beyond their limits can seriously damage the body.

So if each generation becomes stronger and more unstable…

what happens when a human being is born with more energy than their humanity can control?

Hello!

I’m looking for 1–2 beta readers for a short story. Each chapter takes about 5 minutes to read.

Quick summary:

My Hero Academia fanfic

A 10-year-old boy with too much power trying not to hurt anyone

I’m mainly looking for quick impressions:

– Did it feel engaging?

– Does the character feel believable? https://docs.google.com/document/d/1gAWoq8QP5cHUJb8KgOAmzLlg7aa91Sd7W1AtTYUD9TI/edit?usp=drivesdk

I’ve been thinking about a version of humans that evolved a much more efficient metabolism—basically able to use energy from food faster than we do now.

Not infinite energy or anything like that, just quicker access to it.

In theory, this could allow short bursts of higher output (strength, speed, endurance), but it would probably come with some serious biological downsides.

My guess is that something would start to fail pretty quickly if this gets pushed too far. Overheating seems like an obvious issue, and oxygen delivery might become a limiting factor as well. I could also see long-term cellular damage building up from the increased metabolic rate.

I’m also wondering what kind of physical or anatomical changes would even be necessary to support something like this in the first place.

I’m trying to keep the idea grounded in biology rather than going full sci-fi, so I’m mostly interested in what the realistic limits and trade-offs would look like.

In this setting, certain humans possess an abnormal metabolism that converts food into usable energy far more efficiently than normal.

They can access that energy almost instantly, allowing short bursts of enhanced output—strength, speed, and heat—but only for brief periods.

However, this comes with clear biological limits:

heavy dependence on food intake

rapid depletion of internal reserves

buildup of heat and metabolic stress

internal damage if overused (pain, overheating, collapse)

no sustained high output

These individuals are not invulnerable—just able to access energy much faster than usual.

If one of them repeatedly pushes this ability in a short period of time, what system fails first?

Hi, I had a sci-fi idea and wanted to know what people think.

What if a human body could convert food into extremely efficient energy — almost like a biological battery?

Not infinite power, but enough to:

enhance strength and speed

recover faster

release short bursts of energy

With limits like:

needing constant food

risk of internal damage if overloaded

Would this feel like good sci-fi… or too unrealistic?

Gael didn’t hesitate… at first.

His mother’s scream cut through everything.

But then he saw the girl, on the ground, struggling to break free.

Two directions.

One body.

One second.

He ran.

The silence afterward was worse than any scream.

In that moment, Gael understood something:

he didn’t choose between right and wrong…

he chose which pain he was willing to carry.

And you…

if there is no right choice,

who do you save… and what guilt can you live with? 👀
