good quirk ideas

One cool quirk idea could be 'Shadow Mimicry'. The user can blend into any shadow and move freely within the shadow realm, also being able to mimic the actions of those whose shadows they are in. It gives a lot of stealth and surprise attack possibilities in a fanfiction.

A fanfiction could focus on a new character with an explosion quirk who joins Naruto's team. This character might have a mysterious past related to a secret organization that was experimenting with quirks in the Naruto universe. Their explosion quirk would add a new dynamic to the team's combat strategies, and there could be a lot of fun interactions as they adjust to working together.

One idea could be an OC who discovers their psychokinesis quirk gradually. They start with small things like moving a pencil, then as they train, they can lift heavier objects. This can lead to an interesting story arc of self - discovery.

A plot could involve Female Izuku being part of a secret group that has Titan Quirks. They are being hunted down by an evil organization that wants to use their powers for their own malicious purposes. Izuku has to use her wits along with her Titan Quirk to outsmart the bad guys and protect her group.

One idea could be a fanfiction where Deku's quirk suddenly mutates. Instead of just having One For All, he starts to develop an additional power related to it, like the ability to share a fraction of One For All's power with his friends temporarily to boost their own quirks in a time of great need.

One idea could be to create a fanfic where a character has a quirk that allows them to manipulate time within the toon world. They could use it to fix mistakes or prevent disasters. Another idea is a quirk that lets a character bring toon characters to life in the real world, leading to all sorts of chaotic and fun adventures. And perhaps a quirk that enables a character to transform into any toon object, like a cartoon hammer or a bouncing ball for combat or utility purposes.

One idea could be a crossover with the "Harry Potter" universe. Izuku could have his own quirk and attend Hogwarts, facing challenges in a magical world while also dealing with his normal quirk - related issues. Maybe his quirk could interact in unexpected ways with magic.

One idea could be that Harry's quirk is the ability to communicate with magical creatures in a more profound way. This could lead to him uncovering secrets about Hogwarts' hidden areas where these creatures live. For example, he might discover a new breed of dragon that has been long forgotten.

Another plot could involve Izuku being part of a secret society of heroes with vampire quirks. They have their own set of rules and ethics regarding using their powers, and Izuku has to learn to navigate this new world while still aiming to be a regular hero.

Another interesting plot idea is that Izuku's quirk evolution is tied to his emotions. When he experiences strong positive emotions like hope or love, his quirk becomes stronger and evolves in unexpected ways. For instance, it could manifest as a healing ability in addition to his existing powers. This would make his character development more complex as he has to learn to manage his emotions not just for his own well - being but also for the sake of his quirk evolution.
