Yahiko (弥彦) was a shinobi from Amegakure and once a student of Jiraiya along with Nagato and Konan.

Background:

Yahiko was orphaned during the Second Shinobi World War, and, thus, he started fending for himself, stealing food from others. He later encountered Konan, also an orphan, and the two began to work together to survive. After this, Konan brought another orphan, Nagato, and his dog, Chibi, into the group. At first, Yahiko was upset that she was bringing more people, but he later accepted Nagato and Chibi into his gang. Angered by how unfair the world was to them, Yahiko declared he would become a god to end the fighting.

The three eventually encountered Jiraiya, who looked after them and taught them basic ninjutsu. At one point, Nagato saved Yahiko after an Iwagakure chūnin attacked them. Afterwards, Yahiko vowed to become strong enough to protect Konan, Nagato, and eventually all of Amegakure.

Some time after Jiraiya's departure from Amegakure, the three gained a reputation as a talented shinobi team. Still desiring to create a world of peace, Yahiko and his friends went on to become fully fledged Ame ninja, and gathered many supporters who shared their hope to save their village and the world.

Personality:

Yahiko's personality is similar to Naruto's. His dream was to be a leader of his village, and he never gave up no matter what. When he was alive, Yahiko had a strong "eye for an eye" philosophy. He hated the way Amegakure was looked at by the rest of the world, and hated what it had become. He was defensive of the village, saying that it was his dream to stop the endless rain, which he compared to tears, and protect the nation's citizens. Yahiko wanted to become the ruler of the world so there wouldn't be any more wars.

Among the three Ame Orphans, Yahiko seemed to act as the leader of the group. It was Yahiko who first approached the Sannin to ask for food, and was the first to ask Jiraiya to teach them ninjutsu. He also seemed to act as an older brother for Nagato and Konan, reminding Nagato to not cry and to act more manly (although Yahiko was the one who cried when Jiraiya left them). He also wished to become stronger so as to protect Nagato and Konan. He had faith in Nagato, when he got older.

Abilities:

Yahiko had the ability to use water-based jutsu, although the only example of this shown in the series was Water Release: Violent Water Wave, in which he was able to shoot a jet of water from his mouth.
