Guys, you all have decent scenario in mind , still there ONE scenario that have plagued me (and many more) .... what IF Haku is a real girl! Naruto himself said (s)he was cutter than Sakura .. and by some luck or heavy editing from the writer of Naruto himself, Haku is spared from Kakashi deathly attack .. or in another scenario; Haku is revived by some forbiddden jutsu and guest what, he get genderbend to a girl ...! yeah i should stop here now .....
