Foreword: For my little sister who liked Haku and enjoys playing Haku in the Naruto video games.
For those of you who have caught up to Naruto Shippudden's latest episode, Haku and Zabuza appear again via reanimation jutsu. I didn't mind that Haku looked different because it has been a long time. Yet, the preview of episode 264 had Haku wearing lipstick, and his eyes are more larger and feminine. There's no sense of consistency.
To me, it erases the androgyny of Haku. I liked how his gender is mysterious. That was the joke behind one of the scenes where Naruto commented that Haku looked cuter than Sakura.
