In Greek mythology, Hades did not kill his parents, Cronus and Rhea. Instead, he was one of the children swallowed by Cronus, who feared being overthrown by his offspring. Eventually, Hades and his siblings, including Zeus and Poseidon, were freed by Zeus and led a revolt against Cronus, resulting in the Titan's defeat. Afterward, Hades became the ruler of the Underworld, but he did not directly kill his father.
Yes
Hades the Greek God can not be compared to anyone alive: as no one is the immortal King of the Underworld.
The Helm of Darkness. Anyone who wears it will become invisible. This helmet was made for Hades by the Cyclops.
