Behind Sasuke and Naruto, Shino is one of the strongest of the nine Leaf rookies from Hidden Leaf, yet, oddly enough, remains quite stoic and impassive. He is very quiet and rarely talks. He talks only if he absolutely has to, and not because of lack of intelligence. Rather, he is quick to pinpoint advantages and weaknesses when he fights.
At birth, people of the Aburame clan make a pact with an insect known as Destruction Bugs. In exchange for a lifetime of chakra which the insect's use for food, the host in which the bugs live in can call upon their service whenever they need to. Shino is no different, and has thousands of the insects living inside him. Aburame Shino utilizes the insects by having them sneak attack his enemy, while he distracts them with simple taijutsu. He could also make a clone of himself when in danger, or use a female bug as a tracking device hunting down fleeing enemies.
Shino's first documented fight against Zaku Abumi demonstrates Shino's cool demeanor and strength, as well as his ability to think ahead of his opponent. After the fight, many people, including Naruto and Neji were impressed, but still, much remains unknown about him.
