Simon Brezhnev is a black Russian sushi chef and the co-owner of the Russia Sushi shop. It is implied that Simon was born in the USSR to American parents. Simon is a pacifist and dislikes violence (probably because of him witnessing too much of it while growing up in Russia).
He approaches distraught people on the streets trying to help them by offering sushi. He is portrayed as a strong but gentle giant who often ends up scaring off his customers due to his appearance.
