Haze Shenron (二星龍, Èr Xīng Lóng; lit. "Two-Star Dragon") is the first Shadow Dragon fought by Goku and Pan during the Shadow Dragon Saga. He is the Two-Star Dragon and represents the element of pollution or toxicity. He was born when Upa (one of Goku's old friends) wished his father, Bora, back to life after being killed by Mercenary Tao.
