Harry ducked as a blasting hex whistled past his ear, and returned fire, hitting McNair across the face with a sectumsempra and sending him to the ground. Taking a moment to catch his breath, Harry looked around him at the devastation that was once Privet drive. Several cars were on fire, the house across from No. 4 was smoldering, the entire front having collapsed. Bodies lay on the ground, mostly muggles, but a distressing number were Order members, evidence of the Death Eaters rampage. Water shot into the air from a broken water hydrant, an ever widening pool spreading down the street to sizzle when it hit one of the burning cars.
"So you still live, Harry Potter," a cold voice hissed. "How disappointing."
Harry spun around to see Voldemort striding confidently towards him through the water, casually batting a stray curse away with a simple
flick of his wand.
"Nice of you to come, Tom." Harry answered sarcastically, then tensed, tightening his grip on his wand, ready to dodge if the Dark Lord cast a curse.
"Defiant to the end, but you won't be bothering me any more, stupid child." Voldemort sneered, then cast crucio at Harry. Harry dove to the side, the spell barely missing him, and quickly cast reducto at the Dark Lord.
"Pitiful!" Voldemort sneered as he merely stepped aside, and cast a sectumsempra back. "You'd think the old man would have trained you better," he taunted, taking several steps closer, sending a ripple of water towards Harry.
"I know enough," Harry yelled, stepping backwards as the water flowed closer to his feet. "I know I'll beat you!"
"Foolish child," Voldemort shook his head in mock sadness. "You think the Order of the Phoenix will protect you?" The snakelike man started laughing, gesturing with his left hand towards where his minions were holding the last remaining members of the Order captive.
"You do not have a chance. Drop your wand and I might have mercy on you."
"Never!" Harry yelled, then looking up, he cast a cutting hex at an overhead cable, sending it snaking to the ground where it landed with
a crackle and a blinding flash of light in the water at Voldemort's feet.
It was several hours later and the sun was rising when Kingsley Shacklebolt walked wearily over to where Harry sat on the curb with his head in his hands and sat beside him. Kingsley'd been supervising the cleanup as the Ministry of Magic wizards obliviated the surviving muggles, and the Healers from St. Mungo's worked over those who had lived, so this was the first time he'd had a chance to talk to the Boy-Who-Lived. "Can you tell me how you killed Voldemort, Harry?"
Harry turned to look at the black man and sighed. "You know the prophecy, right?" Harry asked, then continued when the weary auror nodded. "Well, it was the power he knows not!"
Kingsley frowned in confusion. "I don't understand?"
"The power he knows not...electricity!" Harry smirked and gestured towards the street as a large white truck with several long ladders on top, and an orange flower symbol on the side, pulled to a stop just clear of the battle zone. A sign on the side of the truck read "EDF Energy." "I guess he didn't know that electricity and water don't mix!"
AN – EDF Energy is (as far as I can determine – don't hit me I'm a Yank!) the company that supplies electricity to the Surrey area.
