Mishizo is a slightly tall man with a very good build. He has black eyes and hair. He is usually wearing a long black cloak with silver and red collar. Under that cloak he wears a black t-shirt covered by a ninja flack jacket with black pants.
Mishizo was always kind to those who were kind to him. He loves his wife and children. He was always playful with Shizaku and Ryzuk, and loved to train them. Most of the things Shizaku and Ryzuk know where taught by Mishizo himself.
Minato was Mishizo's godfather and had taught Mishizo a lot. Such as the Flying Thunder God Technique and the rasengan which Mishizo mastered at the age of 10. They went on a few missions together and fought together in several battles against opposing villages. Minato believed Mishizo to be a very talented kid. That is why he taught Mishizo anything he could. Mishizo was heart broken when Minato sacrificed his life to protect his son. Even though Mishizo knew Minato did the right thing in protecting the village, there was so much more he wanted to learn.
He married his teen love, Mayumi Uchiha, who he met while he was assigned on a mission with a few of the Uchiha police task force. They fell in love and became Husband and Wife and had two Children, Shizaku and Ryzuk. As Shizaku grew older, Mishizo spent lots of time training with him, since Ryzuk rather trained alone or trained with his mother. So Mishizo would always bring Shizaku out to cool training spots to work on his ninja skills. Mishizo believed Shizaku was just as talented as he, himself was as a child. By the age of 9 Shizaku mastered the Rasengan. Then around when Shizaku turned 10, he was taught a basic slower virsion of the Flying Thunder God Technique. Mishizo gave Shizaku his own few sets of Flying Thunder God Kunai because Minato left his underground basement with the Flying Thunder God Kunai maker and tons and tons of Flying Thunder God Kunai in there.
