Who were the roman god plutos enemies?

In Roman mythology, Pluto, the god of the underworld, had several adversaries, primarily among the gods and mythological figures associated with the afterlife and the underworld. His main rival was Proserpina's mother, Ceres, who sought to reclaim her daughter after Pluto abducted her. Additionally, Pluto faced opposition from gods like Jupiter, who represented the sky and the living world, as well as from figures like Hercules, who ventured into the underworld during his labors. However, Pluto was generally a more isolated figure, ruling over the dead rather than engaging in frequent conflicts with the other gods.
