Power Ring I (Harold Jordan): First, we need to discuss the ring of volthoom, and I need to explain who volthoom is. Millenia ago, on one of the many positive matter universes, there was a warlock named volthoom. A power hungry man, volthoom tapped into the very energies of the cosmos themselves, and made himself a being of pure energy. Acting as a virtual god, he attempted to bend the multiverse to his whims. He nearly succeeded, until the collective forces of the Monitor and the Anti-Monitor worked together to contain him. He was that big a threat.
Once they'd defeated him and stripped him of most of his power, they held a trial. And at the end of the trial, the monitor deemed him guilty. And in yet another example of the monitor dishing out indignity after indignity onto the anti-monitor, volthoom's punishment was to be banished forever to the anti-matter universe. The Anti-Monitor didn't want any part in this power mad warlock, though. He hated him and hated the monitor for pushing volthoom onto him. So he made sure volthoom would be punished in his own way.
More specifically, the anti-monitor ripped volthoom's soul out of his body, and then trapped his soul inside of a ring. Volthoom was now just a genie in a lamp, with no real physical form of his own. He would always be a servant to other men's wills. Or well, that was the plan. But the anti-monitor made a few mistakes, and these mistakes allowed volthoom to continue to flourish. Because while volthoom may no longer have a physical form, he's still got a mind. And he's capable of whispering in men's ears, tricking them into using his powers.
And if those men are weak enough, volthoom will literally eat them from the inside out. He steals their energies and burns them up, and it powers himself. If he steals enough energy from enough people, he can feasibly reconstruct his body and make another play for multiversal domination again. So for centuries volthoom's cursed ring has been traveling through the anti-matter universe, stealing men's souls and energies.
And now we get to talk about Harold Jordan. Harold Jordan was a janitor at the ferris aircraft company. He applied to be a pilot years before, but he was consistently rejected for his inability to stay calm while in the cockpit. Angry and bitter about being just a two-bit janitor for a stupid plane company, Harold was amazed when he suddenly saw a spaceship crash out in the fields near the airstrip late one night.
Inside the spaceship lay a dying alien, volthoom's latest victim. This man convinces Harold to take the ring by whispering sweet promises into his ear. You'll have unlimited power, the adoration of millions, you'll finally be a hero… Desperate to believe the words the dying alien said to him, Harold eagerly puts the ring on his finger. And this was the beginning of the end of his normal life.
Because volthoom now had a new host, a new victim to drain energy from. For a few years he hid his existence from Harold, though. For a good few years, the name of Power Ring actually meant heroic things to the people of the anti-matter earth. He was actually a good man doing good things. But then…things began to spiral out of control. Whenever Harold tried to get the ring to do things, it wouldn't do it. It began demanding complete obedience, and it would haunt him with horrifying visions until he complied.
So by the time Power Ring joins the Crime Syndicate, Harold Jordan is an utterly broken man. A spineless coward who can barely close his eyes without seeing volthoom's terrifying visions, harold isn't even in real control of his actions anymore. He hates most of the others in the crime syndicate, but he has no backbone to stand up for himself. And he's also beginning to suffer from a constant fever, a sign that volthoom is beginning to burn him up and consume him…
Although it isn't all bad for Harold. When the Justice League Canada ends up on the anti-matter earth, he manages to follow them back to the positive matter universe (volthoom ordered him to, seeing it as a chance to begin taking over the multiverse again). But once in the positive matter universe, the Justice League are able to figure out that the ring is controlling his every action. And they successfully manage to free him of it's influence. Still, volthoom and his ring escape from the league's headquarters before anyone can destroy it completely. So he'll probably find a new host before too long…
But in the meantime, Harold Jordan has his life back. Sure, the positive matter earth is different from the negative matter earth he used to call home. But he's finally free of that damned rings influence. Maybe he can finally begin to live again. But seeing as he's homeless, I see him living with the Justice League as he goes to therapy and tries to work on his lingering issues.
