I'm going to assume that you're asking which son of Zeus killed Medusa, in which case the answer would be Perseus.
Poseidon was Medusa's boyfriend and they were hanging out in Athena's temple. Then Athena turned Medusa into Medusa.
Medusa did not, no.
You are turned to stone.Anyone who looked at Medusa was turned to stone.
In the Percy Jackson series, Annabeth is the daughter of the goddess Athena. Athena had caught Medusa and Poseidon together (in a manner of speaking) in her temple, and was furious. As a result, Medusa became a monster with snake hair and the ability to turn people to stone. Hence, in the books, Medusa is angry at Annabeth because Medusa dislikes Annabeth's mother, Athena.
because her head can still turn people into stone so she doesn't need her body.
Athena put the head of Medusa on her shield.
because her head can not disintegrate like the rest of her for it can be used to help in war by turning people to stone and even when Medusa is dead even looking at her can still turn you to stone.
Perseus cut off medusa's head by using the sheild that Athena gave him to watch the sleeping medusa and then he cut her head off with a sword.
He did not, Perseus was sent to fetch the head of Medusa by King Polydektes of Seriphos.
Medusa died in her lair in the garden when Perseus cut of her head
Perseus gave Athena Medusa's head because she lent him her shield. Athena then put the head on her own, shield where it remains.
The hero that cut off Medusa's head was named Perseus. Who then gave the head to Athena.
yes it is
Athena
Medusa(:
