Shino Aburame is a very mysterious character of this anime. Because he's a member of the Aburame Clan, his special skill is that he has insects in his body that feed of his chakara. He then utilizes these insects for attacking and defending (or cheating, as he did on written portion of the Chunin test). Some of his abilities is Bug Host and Bug Clone. These bugs obey whatever he orders them to do. These bugs are really harmful because they eat chakra. Everyone in Shino's family wears the sunglasses. Because of this, people think that there is something wrong with Shino's eyes. There is nothing wrong with Shino's eyes, though he might see like a bug. Shino (and his whole family) are, as babies, left to insects and become the insects home. Thats how the Aburame family get the bugs they control.
