Healing factor

It can never heal something they did not feel first.

Source: A secret programme that lost their file
How it shows: They heal a paper cut by the time they reach the kitchen.
Limit: Can be switched off by one particular person, who is not them.
Cost: It takes a day of rest to recover after a big use.
How it could grow: A gentler cousin of the power could wake: calm instead of command.

Power from a name (optional)

The same name always gives the same power. A name stays on this page: links, copies and images never include it.

Keys: R rolls a new power, C copies it.

How it works

Choose a setting (Superhero, Fantasy or Sci-fi), a strength from Useless to Overpowered, and whether the power belongs to a hero or a villain.
Press New power, or R. The tool rolls a power and the five things around it: where it came from, how it shows in a scene, a limit, a cost and a way it could grow.
Lock the parts you like and roll again to change the rest, or reroll one part on its own. Switching between hero and villain keeps the power and changes only how it is used and what it costs.
Or type a name in the box. The same name gives the same power every time, and the name stays on the page: copies, images and links never include it.
Copy the power with C, copy a link that brings back this exact roll, or save it as an image. Powers you rolled earlier on this visit are listed under the tool.

Six parts, one power

The power names the idea and what it can never do. Its source says where it came from, a scene shows it at work, and a limit, a cost and a way to grow turn the trick into a character. Every limit and every way to grow is written for the power’s own family, so none of them is a rule for some other kind of gift.

What makes a power interesting

A power on its own is a list item. “Controls fire” tells you what the character can do and nothing about what the story will do with it. The interesting part is the edge of the power: where it stops, what it takes and who gets hurt when it goes wrong. A reader will forgive almost any gift if the rules around it are clear and the character keeps paying for it.

That is why every roll here has six parts rather than one. The power is the idea. The source says where it came from, which hints at who might want it back. The scene shows it at work, in a moment you could write. The limit, the cost and the way it could grow are what turn a trick into a character.

Limits are where the scenes come from

A limit is a rule the power obeys, and a good one makes the plot for you. Take a teleporter who can only go where they have been before. Suddenly the unvisited city is a problem, a map is treasure and a friend who has travelled a lot is worth more than a sword. Take a mind reader who cannot touch a mind that is expecting it, and every careful, suspicious character becomes a door they cannot open.

Each power here carries a line on what it can never do, so you know the far wall. The limit is the nearer wall, the one the character bumps into every week. Limits are drawn from the power's own family, so a luck power gets a limit about luck and a power over stone gets one about stone, never a rule that belongs to a different kind of gift.

A cost turns a gift into a choice

If a power is free, the character should use it every time, and a story where someone solves everything the same way goes flat by the second chapter. A cost makes each use a decision. A tired body, a lost memory, a favour owed or a friend who drifts away all ask the same question: is this worth it today?

Costs scale with strength in this tool. A useless power costs hiccups or a pair of pink ears. A balanced one costs a day of rest or a happy memory. An overpowered one costs something permanent, because a gift that big with no price is a cheat. Raise the strength and the price rises with it.

Useless powers are not wasted

Few generators offer a proper useless end of the scale, and it may be the most fun to write. A character who can only warm a cup to the temperature of a cup of tea is funny in the first scene and sympathetic by the third. Everyone around them has an exciting gift, and they have a small, reliable one they cannot get rid of.

Writers use these powers in three ways. A comedy needs a hero who is always slightly out of their depth. A drama can use one as a quiet insult, the thing a rival teases. And a twist can hide a useful trick inside the absurd one, the day somebody finally needs a pigeon charmer. Every useless power here is real and reliable, which is exactly what makes it hard to ignore.

Hero or villain: the same gift, a different use

A power does not come with a side. Fire shaping warms a cold street in one story and burns a rival's lawn in another. The light switch changes the scene and the cost and leaves the power alone, so you can try both on the same gift and see which story you would rather tell.

The villain lines stay small and human on purpose. They are petty, controlling or proud rather than cruel, which suits a story for teenage readers and makes better writing. A villain who uses a gift to win an argument is more believable than one who ends the world, and often more frightening to the hero who has to live next door.

Growth, and keeping an overpowered character fair

A power that never changes is a scene you have already read. The last line of each roll suggests a way it could grow: reaching further, lasting longer, finding a second use or waking an opposite in a faraway city. These are seeds for later chapters rather than rules, and they are written for the family of the power, so they always make sense.

If you pick Overpowered, give the limit as much room as the power. A character who can do almost anything needs a rule that sometimes says no, and a cost that never lets up. Players at a table feel this too: the strongest character is the one with the heaviest bill, and the game stays fair because everyone can see it.

Questions

Is the Superpower Generator free, and does it use AI?: Yes to free, and no to AI. A power is put together on your device from lists a person wrote, so there is no account to make and nothing you roll or type is sent anywhere.
How does the name box work?: The name is cleaned (capitals, extra spaces and emoji are ignored) and used as the seed for the roll, so the same name always gives the same power at the same strength. The name stays on this page. Links, copied text and saved images hold the power and nothing you typed.
What do the strengths mean?: Useless powers are real but almost no help, such as a talent for sorting socks. Everyday powers are small and practical. Balanced powers matter in a fight and obey clear rules. Overpowered powers are enormous, with limits that bite harder and costs that never let up.
What changes when I switch between hero and villain?: Only how the power is used in the scene and the line about its cost. The power, its source, its limit and its way to grow stay as they were. Villain lines are petty, proud or controlling rather than violent, so they suit teenage writers.
Can I use the powers in my own stories and games?: Yes. Anything you roll is yours to use, change and publish, in a novel, a webcomic, a campaign or a role-play server. You do not need to credit us. The powers are original and use no names from published superhero or fantasy worlds.
Can I keep a power I like?: Press C to copy it as text, use the link button for an address that brings back this exact roll, or save it as an image. Earlier powers from this visit stay in the list under the tool until you leave the page.
