When secrets come to light, When evil makes its move, When darkness drowns out the light. What can a hero do? Armed with knowledge long lost, wielding a power never seen before and aided by most surprising of allies, Harry Potter steps into the Dark... A Dark!Harry/Multi story with Evil!Dumbles, Traitor!Ron and PotionQueen!Molly. Rated M for gore, violence and sexual situations.

Or 'Why Moony is afraid of red-heads.'

Lily Evans had a secret. James Potter loved her despite it. Harry Potter has a secret... A Creature!(Powerful!)Harry story with Reasonable!Staff (-Albus), Good!Snape, Smart-ish!Villains and quite a bit of weirdness, magical and otherwise.

Harry Potter was always destined to be great. He was not destined to die in the Chamber of Secrets. However, the method that ensured his survival may have had... some side effects. Rather considerable side effects. Result? A very much gray and pragmatic Harry, secrets long forgotten and a rebellious magical castle... Oh, and a dark lord or two as well. Just another day of Hogwarts.

Harry Potter pays a visit to an 'old friend'. Dark!Harry, implication of H/Hr.

While Harry waits for his girlfriend to return from her 'camping trip' he gets an unexpected visit that changes everything. Rating because of some language and I'm paranoid.
