Hello, I'm an expert in mythology and cultural studies. When it comes to deities associated with the dead, there are various figures across different mythologies. Here's a comprehensive answer:

In Greek mythology, Hades is the god of the dead and the king of the underworld. In Roman mythology, the equivalent figure is Pluto. Both Hades and Pluto are brothers of Zeus/Jupiter and Poseidon/Neptune, respectively, and they rule over the realm of the dead.

In Egyptian mythology, Osiris is the god of the afterlife, death, and resurrection. He is often depicted as a green-skinned man, symbolizing rebirth, and is one of the most important gods in the Egyptian pantheon.

In Norse mythology, Hel is a being who rules over a realm of the same name where the dead reside, although it is not exclusively for evil people as sometimes mistakenly thought.

In Aztec mythology, Mictlan is the underworld and Mictecacihuatl is the goddess of the dead, often associated with the afterlife and the protection of bones.
