I figured that this is the only way Harry can be a Horcrux and still fulfil the Prophesy.
I originally wrote this as a theory in my forum (fell free to visit...) in a summarised form and figured I should make it a proper one-shot. So here it is, slightly more detailed and very silly.
Disclaimer: The following one-shot contains JKRowling's characters but certainly not her ending!
Harry is a HorcruxHarry stood before the quivering Dark Lord, whose only remaining 'dark' embodiment was the ash strewn across his serpent-like features, and ordered his companions to tie the man's legs together in case he attempted one final futile escape.
'It's over Voldemort,' Harry said directly, wiping sweat off his forehead. 'Tonight you and all the pieces of your soul will be destroyed.'
Instead of looking defeated Voldemort gave Harry a look of triumph. 'And what about you Harry? You see, I made you a Horcrux too. So even if you kill this body of mine now, I will still live in you!'
Harry's lips curved into a wicked grin. 'Don't you think I thought of that already?'
He lifted his wand. It was as though time stopped moving. One last glance between the powerful enemies before a flash of green light exploded from Harry's wand and Voldemort lay crumpled.
In a dash, Harry grabbed his Firebolt and muttered an incantation causing a part of his soul to entre the broom!
Then he killed himself with another spell.
Now Voldemort was gone forever, no soul anywhere. But Harry still had a bit of his own soul in the broom so was not totally dead.
Suddenly the broom jumped up, dipped itself in a pile of ash and wrote on a concrete wall, "Wormtail! Time to make a potion to resurrect my body!"
And Gryffindor had a party...
