Madara-centric stories

He may a jerk, but truth be told: he's awesome. So I'm looking for a Madara-centric stories, or have one where he plays a major role in the story.

I read one where he goes to the past as a little girl. Another one is where he ends up adopting Naruto, albeit he doesn't know he is the son of Yondaime.

Please, no Uchiha!Naruto, unless it's really good.
