HP:The power of oa

Suddenly the Watchtower superstructure shook and red alert beacons started to light up. Harry knew what to do, having been drilled by Batman many times and sought the nearest access chute that lead straight to a life pod. As he slid into the small pod, its doors closed immediately and it was launched into space, towards earth.

Harry immediately stared back at the Watchtower and he could see from the small view port strange alien ships attacking the large structure. His fists clenched tightly... he wanted to help somehow... Bruce... Diana and Kara was ther with his many friends and uncles. The Watchtower's massive dock bay three blast shield exploded as strange ships entered, stroming through the headquarter's defenses.

"No!" he cried out, and his chest pulsed. He had many friends inside the Watchtower that helped him, befriended him and cared for him. His family was there. The young boy's breath was seen through the glass as he pressed his hand hard into the porthole as if he longed to reach the Watchtower that by the distance was about the size of his hand. He grew angry and soon he heard an ancient wispy voice in his head.

'do you wish to save your friends, Harry Potter?' he heard in his head

"I do" Harry said aloud as he observed the battle before his eyes.

'then learn the knowledge of Oa, Harry Potter, for you posses all my power'

Harry's eyes went to the back of his head at the sudden information flow then snapped his eyes open.

'speak the ancient words the mighty green lantern corps once spoke' the voice said.

His eyes turned glowing green as he spoke with conviction and determination.

"In Brightest day, in blackest night,

No evil, shall escape my sight,

Let those who worship evil's might,

Beware my power, Green Lantern's Light!"

Green aura enveloped him, and his green eyes flashed with power . His clothes changed, and suddenly he wore black overalls with green stripes on the side, and a lantern symbol on his chest. He wore a black coat that was open on the front and reached his ankles with the lantern symbol on the back. He did not have a mask, for he did not feel the need to hide his identity. His escape pod burst open in a burst of green light, and Harry, surrounded with green energy and determination on his face, joined the battle.

Diana shielded herself against the bolts and ducked again. The Thanagarian invaders had launched their whole armada against the watchtower, completely taking them by surprise. They quietly disassembled one long range beacon after another, as not to alert the watchtower's security systems. Things were getting hopeless, as most league members could not fight in outer space. She saw Green Arrow run, being pursued by four Thanagarian warriors. Diana threw a storage cabinet at them, and Green Arrow shot the groups with sleeping gas.

They were slowly pushed back into the command center, where the other justice league members held for a last stand. She saw hundreds of Thanagarian space superiority fighters overwhelming the clumsy space vehicles the Earth has sent to aid the outmatched and outgunned Javelin Fleet. If the watchtower should fall the earth was doomed. She saw Batman's space fighter getting pursued by four fighters, their more advance engines made them close in on Batman. Diana prayed that someone would rescue them. Suddenly familiar green beams destroyed the pursuing fighters, and a green figure sped through towards the mothership, destroying anything on its path.

'The Green Lantern corps!' Diana thought excitedly, they were the police force of the galaxy, and they could stop this invasion! She eagerly looked for more green beings, but she only saw the one that helped Bruce. She gasped as the Mothership fired it's cannon at the watchtower, intent on finishing the League quickly for the Thanagarian commander noticed their forces getting demolished . They thought the retired Green Lantern Corps had returned. It was not the whole corps, but that one green lantern sure fought like a whole battalion, destroying multiple targets at a time. He might be an elite corps, Diana thought. The particle shot made by the ship headed exactly to Diana's position, but she saw the Green lantern stand between the tower and the particle shot.

Her eyes widened along with Green Arrow when they saw who the elite Green Lantern was. "HARRY! Get out! You cannot deflect that!"Diana cried banging her fists against the duraglass. But then Harry glowed even brighter and with calm resolve focused his will on forming a mighty shield. The voice said his power was only as strong as his will, and his will to protect his friends and family rivaled none. A huge wedge shaped shield formed, and when the particle shot hit the shield, the shield deflected the shot towards a group of invading Thanagarian ships on reserve. They all blew up, and nothing of the reserve force was left. Mouth hanging open, Diana just watched in shock at what Harry did next.

Harry's mighty wedge shaped shield was still formed, and he focused now on the mother ship, that was now slowly retreating, hundreds of space fighters landing on its many docking bays. They would not escape justice he thought and gave a mighty push, and the shield travelled an amazing speed towards the mothership, slicing it into two. The mighty Thanagarian Warbird class, flagship of the Thanagarian invasion fleet drifted apart in two pieces, and the two halves slowly moving before they exploded in a ball of gas and heat. The explosion expanded consumed the whole ship and the surrounding area. Diana heard the other League members gave a mighty cheer, as the Thanagarians on board surrendered dropping their weapons to their feet.

"Diana, I'll go with Harry, you take command of the watchtower." Diana heard Bruce speak on the communications device in her ear. She replied to him and stalked away. Ooh that boy was in for a talking to! Kara appeared and she looked like she was panicking. "Harry! His life pod blew up!" The 13 year old was crying, and Diana hugged her and said "Harry's alive don't worry Kara, I saw him earlier.
