Hades

Roman Name: Pluto

Parents: Cronus and Rhea

Siblings: Zeus, Poseidon, Hera, Hestia, Demeter

Relationships: Persephone was the wife of Hades. He kidnapped her from his sister Demeter. 

Children: Makaria

God of: The underworld was his home and he was the ruler. He was a very gloomy scary looking god. Some did not believe that he should be considered as an Olympus God, but he is one even though he lives in hell. 

Symbol: Hades symbols were his helmet and his three headed dog named Cerberus. The helmet was his tool that he used when he wanted to be invisible. This helmet was given to Hades by the Cyclopes. 

Greatest Accomplishment: Hades lived in the underworld so he did not achieve many great accomplishments but one of the things he did participate in is helping his brothers and sisters fight against the Titans. He also helped wound his father Cronus. 

Worst Deed: He became an enemy of Demeter because he kidnapped her daughter Persephone who he made his wife. Even though this is something I would consider as a bad deed most considered  it a great accomplishment because of the fact that he was successful in kidnapping her.
