How Many Potters?!? (This Story Is Under Being Rewritten)

Harry Potter was created by J.K. Rowling
Percy Jackson was created by Rick Roidan
Danny Phantom was created by Butch Hartman

What would happen if Sally isn't really Percy's birth mother, what if it was Lilly Evans who had Percy before she married James and the fates took Percy away for his own destiny.
What would happen if Harry Potter wasn't an only child and instead had a twin brother and an older brother.
What would happen if Danny Fenton was really a Potter and the twin brother of the chosen one?
What happens when three brothers reunite after all these years?.....And what better place to do it than Hogwarts school for witchcraft and wizardry!

Read to see what happens when you put all the Potters in the same place....how many things do you think will explode by the time this first year is done!

I don't own any of the characters except for some OC's and the plot is mostly mine.
This book starts at the summer before Harry's second year st Hogwarts.
