Harry Potter and the Alternative Beginning
*Cue theme music*
"Lily! He's here!" James screamed. "Take Harry and run!"
Before Voldemort had time to attack, there was a loud noise that made James nearly shite his trousers. Voldemort fell on the ground, red blossoming on his robes like a flower. James gaped and turned around. There was Lily, a contraption in her hand that he didn't know the name of—he didn't pay much attention during his muggle studies. She lowered the gun and tossed it aside.
Author's Note: I know you have to take in account of the horcruxes, but shut up and stop ruining this for me! I never understood why somebody didn't just shoot him. It's not like it was a foreign concept to muggle-borns/raised like Harry and Hermione. Mind you, I haven't read the last two books, so maybe there is an explanation for why nobody shot the shit out of him.
