Shippou: Inuyasha's largely ineffective comedic relief/baggage.
Oh God, I hated Shippo too. And Sango. They were just so bland and they got on my nerves after a while. I don't even remember seeing Shippo or Sango actually fight in the Inuyasha anime very much :x
I've got another one: HIDAN from Naruto. That guy was too damn creepy, vulgar, and weird! Plus, he killed Asuma! D8
Hidan was actually my favorite character in Naruto Shippuden for some reason. He had personality, unlike his partner. Kakuzu was as boring as can get, which was reflected in his fighting style.
