She could change anyone to stone.
Step-by-step explanation:
- Medusa disguised herself as Aunty Em who owned a Garden Gnome Store. When Annabeth saw her, she could not recognize her because her face was completely covered with a veil.
- Medusa's face could transform anyone to stone and hence she was capable of making many statues. She had numerous statues that she stored in her warehouse.
- Medusa was able to recognize Annabeth when she saw her grey eyes. The story is a Greek myth and in the end Medusa's head was chopped off by a Greek God.
