About this tool
Generate unique fictional superpowers with descriptions, weaknesses, and rarity rankings. Find your ultimate superpower for stories, games, and fun.
Random Superpower Generator draws one ability at random from a hand-written deck of 30 powers, each with a description, a named weakness, a category, a rarity tier and a power level from 3 to 10. Rarity runs Common, Uncommon, Rare, Legendary and Mythic — only two of the thirty are Mythic, so Freeze Time or micro black holes come up roughly one roll in fifteen. Writers, game masters and players get a power that already has a built-in limitation, which is the part that makes it usable in a story.

Press Generate Superpower to draw one of the 30 hand-written powers at random.
Review the card: category and rarity badges from Common to Mythic, the 10-dot Power Level meter and the named Weakness.
Press Copy Power to put the name, description, power level, rarity and weakness on your clipboard as one block.
The limitation is written into the entry, so you get a story problem rather than an unbeatable character.
Each result carries a tier from Common to Mythic and a numeric level from 3 to 10, which makes powers comparable for game balance.
One click puts the name, description, power level, rarity and weakness on your clipboard, ready to paste into a character sheet.
Thirty, each written by hand across 15 categories including Elemental, Psychic, Temporal, Cosmic, Spatial and Morphic. Every roll is an independent uniform pick, so the same power can come up twice in a row.
There are five tiers: Common, Uncommon, Rare, Legendary and Mythic. Only 2 of the 30 powers are Mythic — Freeze Time and Create Mini Black Holes — so you have about a 6.7% chance, roughly one roll in fifteen.
It is a 1-to-10 strength rating, though the actual entries range from 3 (Elemental Wind, Animal Communication) to 10 (Freeze Time, Create Mini Black Holes). It tracks rarity closely and is there so you can balance powers against each other in a game.
Yes — the descriptions are original writing for exactly that purpose, and generic abilities like flight or telekinesis are not ownable ideas. Just avoid attaching them to a named character from an existing franchise if you are publishing commercially.
