Quirk Idea by Cottonmouth25

QUIRK: Keratin

TYPE: Transformation

DESCRIPTION: The user has full control over the properties of the keratin in their body, such as hair and nails. They can form horns, claws, and other tools by changing the shape, length, hardness, etc. The degree to which they can alter each property can be increased with intensive training.

DRAWBACKS: With overuse, their hair is prone to shedding, and their nails can become brittle and easily broken. To help compensate, the hair and nails grow faster than average.
