Fem Mastemon Deku is a non-profit fan-made chat-based web series in an alternate version of the My Hero Academia universe. All the episodes are made by RimuruTexts.
Fem Mastemon Deku provides examples of:
- Casting a Shadow: One of the eight elemental energies, used by both Azazel (on the left side) and Tokoyami.
- Gender Flip: One of the central premises of the series. Due to Izuku’s dormant quirk rewriting his DNA (or something along those lines), he ends up being changed into a girl, now going by the name Azazel Kayama.
- Elemental Rock-Paper-Scissors: Based on the attribute system used by Digimon Story: Cyber Sleuth, dormant quirks align with one of eight elemental energies.
- Light 'em Up: Another of the eight elemental energies, and used by Azazel (on the right side).
- Yin-Yang Bomb: Shoto, as in canon. In terms of dormant quirks, Azazel is the first recorded instance of someone forming and utilizing neutral energy, a formerly theoretical energy between light and dark.
