A/N: Here is another concept I've been thinking on, just recently come to life- a Harry Potter/Green Lantern X-Over. I'll admit to being heavily inspired by bluminous8 and his fic Harry Potter and the Power of Oa. However, unlike his fic, which features the entire Justice League, this will mostly feature Harry as Earth's Green Lantern.

The premise of this Green Lantern!Harry fic, is that for whatever reason, Harry is chosen from a young age to become a Green Lantern, with all of the strengths and weaknesses that come with having such an immense power at such a young age.

Harry stood defiantly as Voldemort casually strolled into the Ministry Atrium. He had to admit he was slightly surprised by the calm displayed by Voldemort. Their last confrontation had not ended well for the Dark Lord.

Harry felt the telltale prickle of his scar flaring up, but it was mitigated by the fact that he not only was prepared for the pain to hit him, but had his ring was protecting him from mental invasions. While it hadn't been completely able to close off his link to Voldemort, the Green Lantern ring HAD dampened its' effects significantly.

The various witches and wizards who happened to be in the Atrium at the time were astonished to say the least- as there stood the Boy Who Lived, emitting a light green aura with emerald green lightning surging all around him. He dressed in a full black body suit and green sleeveless tunic that had the symbol many had seen at the World Quidditch Cup destroy the Dark Mark emblazoned on the back and on the right side of his chest, along with pure white knee-high boots and gloves. On his right hand was a glowing green ring.

The truth instantly became apparent- Harry Potter and the entity known as the Green Lantern were both one and the same and he was going to rid them of the resurrected Voldemort once and for all. Despite their overwhelming fear of the Dark Lord, they felt a glimmer of hope. However, none could fathom how Voldemort, as mighty as he was before his original defeat by Harry Potter all those years ago could stand so calmly while facing the seemingly all powerful Green Lantern.

After chuckling to himself, Voldemort greeted Harry. "It's been some time, hasn't it Potter?"

Harry's glowing green eyes, unimpeded by his glasses, narrowed a fraction. Voldemort was too confident, too sure of himself. It was not false bravado on the part of the Dark Lord- he knew something, had an ace up his sleeve.

"I will not allow you to escape justice this time, Voldemort," Harry said boldly. Voldemort's smirk grew.

"I don't intend to flee from this encounter, Potter," the Dark Lord retorted. "You will find that things have changed significantly since our last confrontation in the graveyard."

"Explain."

"You are powerful, perhaps more so than any other being to walk the face of this planet. It's no wonder you were able to breeze through that tournament last year, being in possession of powers that are likely cosmic in origin. Because of this fact, you very untested as there is nothing that this planet could offer that could ever begin to push your limits- not even me."

Harry wasn't sure where Voldemort was going with this, but what the Dark Lord was saying was very true. It had been years since Harry truly had felt anything remotely resembling fear and the only time he'd ever been pushed passed his physical limits of how much of the power he could channel through the ring, he'd managed to block Peter Pettigrew's Killing Curse while fighting off the effects of his curse scar.

The effort expended had completely drained him and knocked him unconscious.

"And thus your strength has become your weakness."

That caught Harry off guard.

He'd suspected that if there was anyone who could find a weakness to his inherited powers it would either be Dumbledore or Voldemort, but he couldn't fathom what sort of advantage the Dark Lord had found. While he had to admit Voldemort was likely correct in that his overwhelming power was likely to be his greatest weakness, he failed to understand how the Dark Lord could use that against him.

"It has only been through my greater experience that you have not destroyed me yet. Even with my new body, I realized that my raw talent and skill would not be able to overcome the power deficit. It was painful for me to admit, if only to myself, and frustrated me to no end."

"I suppose you're going to make a point?" Harry asked. His annoyance at Voldemort's monologue was clearly evident in his voice. He knew he should probably strike out at the Dark Lord, but held himself in check, deciding to err on the side of caution in case Voldemort really had come up with something to defeat him.

Voldemort chuckled. "In my mind I went over our fight last summer, as well as our encounter four years ago. Each scenario ended in a similar manner, with me being defeated by your overwhelming power. I had not realized that I had already acquired a means with which to defeat you."

"You're bluffing. If you really had the means, you'd have used it by now," Harry replied..

"I'm nothing, if not meticulous, Harry Potter," Voldemort remarked. "There is a reason that after a decade since I was at the height of my power, people still fear me too much to even say my name."

"Yes… I never really got that," commented Harry lightly. "Tom is such an ordinary name…"

Instead of getting angry like the Shade Riddle had, Voldemort merely laughed- a reaction very unlike the Voldemort he had come to know. "I suppose if there is anyone who has earned that right, it would be you."

Harry must not have concealed his shock as well as he thought, because Voldemort seemed to have noticed it quite easily.

"I respect power, more than anything else, Potter and I've already acknowledged that you are likely the most powerful being on the planet. While I don't like that old discarded name, you, of all people, have earned the right to use it." Voldemort informed Harry. "But that is neither here nor there, because in moments you will either kneel before me, or lie defeated at my feet."

"I don't think so. Even if you've managed to find some flaw or weakness in my powers and abilities, I will not bow to you. I will fight you- even sacrifice my own life, if need be, to take you down with me," Harry declared.

"Then I suppose it's time, my subordinates will have had time to defeat Dumbledore and his Order by now," Voldemort casually stated.

"What do you mean?" asked Harry frowning, his emerald green aura flaring slightly.

"I have studied your powers- observing its' weaknesses and limitations… Its' strengths and potential… I have been able to ascertain much- and all because of an unintended consequence of that ritual I performed at the end of last year." Voldemort nodded, as if signaling someone behind him.

Harry spared a glance and noticed Malfoy and Nott standing in the doorway he'd come through- only they were different- both having donned robed of yellow and black that looked something like a cross between an Auror's and a Death Eater's robes. What caught his eye, however, was the symbol emblazon on the right side of their chests in a similar fashion to the Green Lantern symbol on his own chest.

However their emblems were different than his. Instead of the green lantern-like symbol on a field of white like was on his uniform, theirs possessed a white circle with a 'V' that extended passed it on a field of black. Two curved lines that extended from the top of the 'V' to the bottom ran parallel to the outside of the circle and interested the 'V'.

'How…?' he thought as he noticed the rings on their fingers bearing the same symbol as their robes. But his musings were cut short when he heard Voldemort speaking- reciting an oath, in fact.

"In blackest say, in brightest night… Beware your fears made into light… Let those who try to stop what's right… Burn like my power… Voldemort's might!"

Harry turned but had to cover his eyes at the explosion of yellow light.

'Damn it…' he mentally cursed. He realized then, that the previous incursions were not meant to defeat him, but drain the charge on his ring significantly enough so that these three new ring bearers would be better able to instead.

Sure enough, as the light subsided, Harry noted that Voldemort's uniform was nearly an exact replica of his own. Voldemort lift his fist, his new power ring pointed at Harry. Harry lifted his own ring in retaliation. Voldemort shot a yellow beam at Harry as the latter used his powers to form a disc-like construct to shield himself from the blast.

However, Harry was surprised when the yellow beam merely shattered his barrier as if it were nothing and struck him in his left shoulder, knocking him off his feet. Pain erupted in his body as his right hand went to his shoulder. Though he could not see it, the smell and feel of the charred flesh of his wound told him he was in trouble. He could barely move his left arm and his weakened powers were seemingly useless against Voldemort's own considerable newfound abilities.

For the first time since he was a small child, Harry Potter felt fear as he realized he would not be able to defeat Voldemort at all, let alone as easily as he had during their previous encounters, in single combat. That wasn't taking into account that somehow, Voldemort had granted at least two of his Death Eaters lantern-like powers, whose abilities, Harry was certain, like Voldemort's, would be able to easily counteract his own.

"What's the matter Potter?" asked Lucius Malfoy mockingly. "It must be hard to keep up your superior façade when you're clearly outclassed like you are."

With a blindingly fast movement Harry directed his ring towards Lucius and fired off a bolt of emerald energy that was casually batted away by the senior Malfoy, who laughed mockingly at him.

Harry realized that he had as arrogant as Snape had constantly accused him of being and it had cost him. Never-the-less, he refused to give up. Knowing that direct attack had proven thus far ineffective, Harry sent out a pulse of bright green light temporarily blinding the three yellow ring bearers. He then proceeded to blast a hole in the ceiling of the Ministry of Magic and flew out the top of it.

A/N: Good, Bad, Ugly?

Up to this point, Harry has been drastically overpowered, having only been pushed to his limit twice- the first time when he confronts Quirrel, as he channeled more power than his body could handle and at the end of the Tri-Wizard Tournament, he used his ring to block a Killing Curse.

Voldemort gained his abilities after his resurrection because a small fraction of Harry's power had been absorbed into his body through Harry's blood. Of course since the one thing Voldemort's always thrived from is fear, instead of manifesting Green Lantern Powers, his became that of the Yellow Lanterns (or Sinestro Corps).

Of course, since Voldemort isn't affiliated with Sinestro in any way, I gave him his own symbol. His power ring oath is also a modified version of the Sinestro Corps Oath. At this point, Voldemort has also experimented greatly with his power, having been able to use them for about three quarters of a year at this point. He wanted to be sure he'd be able to use his powers effectively before using them against the Green Lantern. His destroying Harry Potter/Green Lantern was to be his 'coming out' as it were.

However, contrary to a lot fan fiction these days, Voldemort is neither stupid nor incompetent and realized that even with his new found 'Lantern Powers' he might not be able to defeat Harry and thus forged a couple of rings (at least two but no more than four) so he could be better sure that Harry would be defeated.

The next Green Lantern!Harry sequence will conclude this particular segment, featuring a 3-on-1 aerial battle between the Green Lantern and the Voldemort Corps.
