Hm well I haven't watched Naruto either but a lot of people have said that they are identical in a way...hmmm and Yoshihiro Togashi is most likely a Naruto fan too because he drew a picture of naruto in a hunter x hunter chapter...oh well..yeah. Well the voice of Gon is in Naruto too. Gon's voice be Naruto. But Naruto is like them going through tasks or something? That's what I've seen. So I guess in a way, they are pretty similar. Besides them being in Shonen Jump and all in Japan. I forgot, Yoshihiro Togashi also drew another manga character but which one? I don't know.
