Idea... Time Travel Harry who bashes everyone. Hold me with me for a moment here... He bashes on the Weasley's for their blind loyalty, Hermione for her blind Loyalty and obsession with being right, Snape for his pettiness and well everything about him, Amelia for being useless, Fudge for not thinking on his own, Draco for Not thinking on his own, Collin for being a Stalker, Filch for being a child abusing prick, his Worthless family for all of it... Dumbles for his abuse, lies, manipulation and more...
he would be out for revenge for all those who fucked him over, which was basically everyone, and would pop up in the summer right after fourth year... he would kill Deatheaters and take control...
He is from forty years in the future, no romance due to his age... he has been planning this literally since he saw Hermione's Time Turner...
He is not the lord of a bunch of families, nor is he massively rich but is well off as he is in canon...
He is nobodies friend, realizing that all of the Wizards are worthless in their own way and hates them...
Love, your Ninja Overlord,
Mika.
