Answer 2

Am not sure but I use to watch them in Mexico and there is a lot of episodes the first chapter are when they are trying to find the cloth of sagitarious and they fight the patriarch of the 12 colums because athena get and arrow on her heart and the knights have to find the guardians of the 12 colums and the second season its about the knights fighting with the queen of asgard she believes in Odin the god and puts the world in ice she freses the world and athena sacrifices herself to save the world and the knights help her too and the 3rd season its about poseidon he falls in love with athena she rejects him and on revenge he tries to sink the earth with water and athena does not want that to happen and she asks the knights to help her save the earth. Those are the only seasons that I know that exist and there is three diferent movies about them. Its a really interesting anime you learn a lot about greek methology with that anime hope this anwser helps you. Good luck
