I like games based on anime works, I especially like mmorpg games, among all anime-based games, Naruto-related games are the ones I play the most. Recently, I've been playing Naruto Online, its quality is not bad at all, the characters and sceneries are close to the ones in the anime and the Ninjutsu art and effects are superb.
Orochimaru is the real deal as a man, however, after starting to investigate techniques to change bodies, his gender started to become a little... confusing. To use such a technique and become immortal, not all bodies were compatible with him, actually, most of the times Orochimaru takes the body of a woman. Maybe that is the reason why Sasuke was always being chased by him online MMORPG game? A male ninja who was compatible with Orochimaru?
The young ninja who was by the side of Zabuza, he was mistaken by a girl ever since he was born; Naruto also thought he was female. Naruto was in for a big surprise when Haku told him he was actually a boy.
Yashamaru was very tender, the feeling I got from him was that he was like this “big sister”, however, his identity was clear: he was Gaara's uncle, a man.
I bet a lot of you must find Neji strange in this list! How can his gender be mixed?!
No one will ever mistake Neji for a woman; however, Neji's clothing and his long hair also show some signs of female-related attires. One chapter of the manga “Rock Lee and His Ninja Pals” also displays some of Neji's more feminine side, it's really adorable!
