The Second Hokage is the younger brother of the First Hokage, Shodai. He, along with his brother, founded the Hidden Leaf Village. After Shodai stepped down from being Hokage, Nidaime became the next Hokage. He has very powerful water jutsus (even when there was no water). Some of his attacks include Water Dragon Blast Skill, Water Formation Wall, and Water Wave. He was Sarutobi (3rd Hokage's) main teacher.

When Orochimaru resurrects Nidaime and Shodai, Kin Tsuchi houses Nidaime's soul. After being turned into a killing machine, he fights his former student. Sarutobi finally places a seal on both him and Shodai that their souls go to the "belly of death" which no one can escape.
