Pluto is the Roman god of the Underworld. In Marvel comics he takes the place in the Olympian Pantheon of his Greek Counterpart, Hades.
The oldest son of the Titan Kronos, Pluto was consumed by his father at birth to prevent him from rebelling against him. Eventually he was freed by Zeus and joined his siblings in overthrowing his father. Through the casting of lots the brothers divided up the world with Pluto getting the underworld and rulership over the dead along with all of the wealth inside of the Earth. Being a greedy god, Pluto sought to increase both his material wealth and the size of his kingdom through the ages. When Zeus decided to let worship of the Olympians die off he forbade Pluto from collecting more souls, angering Pluto. Over the centuries Pluto's bitterness grew leading him to rebel several times against Zeus either through outright rebellion or attempts to weaken his position and claim his throne. These attempts have been thwarted by Hercules and Thor.
Although a character originally written as Pluto first appeared in Red Raven Comics #1 (8/1940), Marvel later retconned that character to be the Deviant known as Kro posing as Pluto. This retcon was revealed in Marvel Universe #7 (12/1998).
Major Story Arcs
Of late, Pluto sided with Hera's Olympus Group and put Zeus on trial for crimes against creation. After convicting Zeus and erasing his memory all of Zeus' edicts were nullified. Pluto believed this would place him as sovereign over all, but forgot that it was Zeus's will that kept him in power and faced an open revolt from the damned.
Powers & Abilities
Pluto possesses the conventional physical attributes of an Olympian god, only to a much higher degree than most. Like all Olympians he is immortal he has not aged since reaching adulthood and cannot die by any conventional means. He is immune to all Earthly diseases and is resistant to conventional injury. If wounded, his godly life force would enable him to recover with superhuman speed; it would take an injury of such magnitude that it dispersed a major portion of his bodily molecules to cause him physical death. Even then, it may be possible for Zeus or a god of equal power to revive him. Pluto possesses superhuman strength and his Olympian metabolism gives him far greater than human endurance at all physical activities.
Pluto's extraordinary energy-wielding abilities are equaled among the Olympians only by those of Neptune, and surpassed only by those of Zeus. Only a few of Pluto's many energy-wielding powers have as yet been depicted. Pluto can fire powerful force blasts from his hands, erect powerful, nearly impenetrable force fields, and create interdimensional apertures to enable him to transport himself from one dimension to another. He can weaken an opponent's strength with his touch. Pluto can create mystical flame and sheathe himself with such flame while himself remaining unharmed. Pluto can create weapons of mystical flame, such as a spear or sword of fire, which can paralyze an opponent. It has been alleged that Pluto is less powerful on Earth than he is in his own realm of Hades.
Pluto wears a Helmet forged by the Cyclopses that was made from his essence and is a symbol of his power. The Cyclopses also forged Zeus' Thunderbolt and Neptune's Trident. Pluto's Helm is virtually indestructible as it is composed of the godly substance, adamantine. Pluto's Helm can render its wearer invisible and undetectable by any means.
