Jako

is a leader of a gang of thieves.

Personality
Jako was a self-admitting "rotten person". He is a very cruel man, as he told Sakura Haruno that he would kill her, along with Naruto and Sasuke, as soon as he got his treasure back.

Appearance
Jako has black eyes, brown, spiky hair which he ties into a short pony tail, and a small goatee. He wears a blue coat with yellow lining over a white top and dark-coloured pants underneath. He also wears a light blue scarf around his neck.

Abilities
Jako's main ability is that he can shoot "liquidised" chakra from built-in cannons in his wrist to attack his enemies, or to defend himself. This liquid can be shot at high pressure to cause injury, or can harden around the targets to immobilise them.

Konoha History Arc
He, along with his group of bandits, were travelling with treasure stolen from the daimyō's sister. However, as they're travelling, one of the bandits almost accidently drop the treasure, and Naruto snatched the treasure. Instead of trying to get the treasure back from Naruto and Sasuke, he and his gang kidnapped Sakura. The treasure was later recovered by Naruto Uzumaki and Sasuke Uchiha, who later defeated him and his team.
