Midoriya Izuku
The protagonist of the series. Unlike his canon counterpart, a Villain's attack destroyed Izuku's arm and one of his eyes and damaged his spine, leaving him legally a cripple. But he refuses to let his dream of becoming a Hero die, using his incredible intelligence to develop any number of amazing inventions to pave his path towards becoming the world's greatest hero.- Adaptational Intelligence: Izuku was hardly dumb before, but this fic pushes him into absurd super-genius levels to make up for his disabilities and lack of a Quirk.
- Child Prodigy: Izuku's this in spades, considering he's an Omnidisciplinary Scientist Omniglot.
- Cyborg: Is slowly turning into one, with a cybernetic arm, spine, and eye. He has several different arms and eyes.
- Disabled in the Adaptation: In canon, Izuku has no health issues aside from his own Quirklessness. Here he's Quirkless and legally disabled due to his missing arm and damaged spine, but he's working on remedying the latter.
- Electronic Eye: Izuku replaces his missing left eye with a cybernetic one of his own design that glows a vibrant blue. In addition to restoring his depth perception, it's equipped with telescopic and thermal vision and is a miniature supercomputer that allows him to connect to the internet. He hopes to eventually be able to use it to directly interface with other pieces of technology to remotely control them. It's also removable, allowing Izuku to use CT scans without a hitch and monitor his nerves to prevent damage. He also has a camera function installed so that he can record what he sees, uploading it to a computer via a USB drive in his prosthetic arm.
- Embarrassing Nickname: Katsuki calls him Deku like in canon, while his friend Mashi calls him "ZuZu".
- Kind Hearted Cat Lover: Is fond of the strays that Aizawa cares for, particularly Pumpkin, who has practically become Izuku's pet in all but name.
- Omnidisciplinary Scientist: Izuku is only in middle school, yet his feats in the fields of mechanical engineering, pharmacology, computer programming, neuroscience, and genetics would leave most real-world scientists stumped.
- Omniglot: Izuku is fluent in Japanese, English, German, and Spanish.
- Workaholic: When invested in an idea, Izuku has a bad habit of losing track of time and forgetting to sleep.
Haganehato "Mashi" Mottai
Izuku's best friend. She's Quirkless but fearless and ready to fight in necessary.
- Bully Hunter: Mashi does not take bullies lightly.
- Do Not Call Me "Paul": She tells everyone she's introduced to to call her "Mashi", because it's better.
- Fiery Redhead: She is Hot-Blooded with the hair to match.
- The Lad-ette
- Malaproper: Tends to do this when talking.
- No Indoor Voice: She's very loud (though not to the extent of Hizashi).
- Sir Swears-a-Lot: Mashi can basically match Bakugou in foul language.
Midoriya Inko
Izuku's hardworking and loving mother.
- Glamorous Single Mother: Subverted. Unlike in canon, Inko had to take a job due to Izuku's medical bills and Hisashi's absence from their lives.
- Team Mom: To the Ragtag Bunch of Misfits that she and Izuku have basically adopted into their family, which includes Mashi, Nemuri, Aizawa, and Hizashi.
