Hades, along with Zeus and Poseidon, is the son of the titans Cronus and Rhea. After the 3 brothers were able to defeat Cronus, they divided the Earth into 3 domains. Zeus ruled the skies, Poseidon ruled the seas, and Hades ruled the underworld. Hades is the ruler of all dead beings and their souls.
After a long time of ruling the Underworld by himself, Hades abducted Persephone; the daughter of Demeter, the goddess of harvest. This caused Demeter to be depressed and therefore all plant life died and decayed. Zeus finally set up an agreement with Hades; Persephone can only stay in the underworld for once a year.

Hades sits on a throne made of ebony, and carries a scepter. He also has a helmet, given to him by the Cyclopes, which can make him invisible. Hades rules the dead, assisted by various (demonic) helpers, such as Thanatos and Hypnos, the ferryman Charon, and the hound Cerberus. Many heroes from Greek mythology have descended into the underworld, either to question the shades or trying to free them. Although Hades does not allow his subjects to leave his domain, on several occasions he has granted permission, such as when Orpheus requested the return of his beloved Eurydice.
The reason I chose him
is that of all the Gods, he has the most difficult duty. In the history of man,
billions of humans have already died. All of those souls will go to the
underworld and it is Hades’s task of making sure that all of those souls
reaches the underworld and make sure that not a single one of them escapes. He
also does this task by himself, and he barely has any communication with living
beings, which makes this task much more challenging.
