Sakon
Sakon and his twin brother Ukon were members of the Sound Four, a group of ninja who served under Orochimaru. They were both skilled fighters, and their unique abilities made them a formidable team. Sakon had the ability to control insects, and he could use them to attack his opponents or to spy on them. Ukon, on the other hand, had the ability to merge with Sakon's body, making them one powerful fighter.
The twins were both very loyal to Orochimaru, and they would do anything to please him. They were also very close to each other, and they would often fight side by side. However, their loyalty to Orochimaru eventually led to their downfall. When Orochimaru betrayed Konohagakure, the twins were forced to fight against their own village. They were eventually defeated, and Sakon was killed in battle. Ukon survived, but he was left heartbroken by the death of his brother.
Sakon and Ukon were both very interesting characters, and they played an important role in the story of Naruto. They were a reminder that even the most loyal followers can be led astray by their leaders.
