"Accio, Voldemort! Accio, Tom Riddle!" Harry Potter shouted in no particular direction.
Wand in one hand, rocket launcher in the other.
ten minutes later
The Almighty Dark Lord of evilness known as Voldemort, fell from the sky, creating a big Dark-Lord-Shaped dent in the grassy landscape.
Harry took advantage of his opponents temporary discombobulation to speak, "Asta lavista, Baby!"
Harry pulled the trigger and blasted that epitome of evil to kingdom come and Timbuktu.
He put the rocket launcher down on the charred grass and thought to himself. Why didn't I think of this before?
I claim Divine intervention.
