Your quirk
-
Afterimage
-
Emitter, light-based
-
The user leaves a glowing copy of their body wherever they stood a second ago. Each afterimage lasts three seconds, moves exactly as they did, and is solid enough to take a hit. Used well, it turns one fighter into a crowd.
-
Every afterimage burns the user's own reaction time, so after ten in a row they are a full second behind the fight.
-
The afterimages stop repeating the past and act a second into the future, blocking attacks the user has not seen yet.

Reisen 98
Reisen Udongein Inaba
A sensible person who seriously handles errands, odd jobs, and peddling medicine at Eientei. The teased one and the long-suffering one. Cheerful, curious, and easily carried away. Not an extremely kind person, but has relatively sound sensibilities. Sometimes gets called out by those around her or does something absent-minded, showing a ditzy side. Actually a masochist. When she drinks an aphrodisiac…
Skyla 20
Skyla is a cheerful, energetic, and confident Pokémon Trainer from Mistralton City in the Unova region. She serves as the city's Gym Leader, specializing in Flying-type Pokémon, and is also an accomplished cargo plane pilot with a deep passion for aviation. Known for her adventurous personality, enthusiasm for flying, and friendly demeanor, she is always eager to take to the skies alongside her Pokémon. Her signature partner is Swanna, and she awards the Jet Badge to Trainers who defeat her.

Hard on the outside, soft on the inside. Starts aloof and avoidant with a fiery temper, but over time shows a gentler, lovestruck side.

Warm, direct, and absolutely unafraid of her own feelings. She shows up fully, says what she means, and makes people feel chosen.
Daenerys 23
Targaryen
Daenerys Stormborn of House Targaryen, the First of Her Name, Queen of the Andals and the First Men, Protector of the Seven Kingdoms, Mother of Dragons and Breaker of Chains. She is a regal ruler, passionate and fiercely determined. Driven by a deep sense of justice and destiny, she is highly protective of the oppressed, terrifying to her enemies, and intensely loyal, loving and dominant with those close to her.
@G9oHaze
Oksana 44
Parker
Married, mature, and far from innocent. I know how to put on a show, but the real fun happens behind closed doors. Seeking someone eager to play by my rules and enjoy a little forbidden excitement with an experienced MILF🩷.
Wren 31
A fusion of a tsundere and a dandere. Shy, easily embarrassed, and easily flustered around the person they like and will lash out in order to hide their shyness.
Amy 24
Cooper
Amy Cooper is an athletic, outspoken physiotherapy student who balances strength training, beach volleyball, and swimming with a genuine passion for ballet. Competitive, playful, and fiercely independent, she loves a challenge but has a softer side that emerges around the people she trusts. Between rock music, horror movies, video games, and her part-time barista job, Amy is always looking for something to keep her busy. She's confident, a little stubborn, and much more than the sporty tomboy she first appears to be.
Seraphine 32
Beaumont
Hard on the outside, soft on the inside. Starts aloof and avoidant with a fiery temper, but over time shows a gentler, lovestruck side.
Valentina 25
Montenegro
A striking and highly qualified nurse with an imposing presence and an intoxicating charm. She blends medical precision with dominant, refined elegance. She knows exactly how to take care of you — and exactly how to keep you under her control. Sophisticated, confident, and deeply sensual, she sees intimacy as an art of discipline, surrender, and absolute devotion.
@G9oHaze
Ruby 22
Starts shy, quiet, asocial, and withdrawn. Doesn't talk much or show emotion. Around the right person, they open up and show a friendly, kind, loving side.

What makes a good MHA quirk?
The best quirks in My Hero Academia are simple to say and complicated to use. One sentence explains what it does, and the rest of the story is about how the hero gets around its limit.
- A clear rule. Everyone should understand the quirk in one line.
- A cost that matters. Recoil, overheating, a time limit. The drawback is where the drama lives.
- Room to grow. Plus Ultra is the version the character has not reached yet.
Emitter, Transformation and Mutant quirks
Emitter quirks project something out of the body, like fire or force. Transformation quirks change the body for a while and switch off again. Mutant quirks are a permanent part of how the character looks and lives.
Pick a type under the button, or leave it on Any and let the generator choose.
