Haze Shenron

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 2 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.
Although he seems to have tremendous durability, Haze Shenron is physically the weakest of the Shadow Dragons; he felt a great amount of pain when a single brick fell on his foot, and Pan was able to completely dominate him by herself. However, his elemental abilities are his trump card; the pollution he generates slowly weakens normal beings, so while he remains relatively weak when it comes to scouter readings, his opponents gradually weaken until he is able to overpower them. However, his pollution has no effect on non-organic beings, such as the Machine Mutant Giru.
After his pollution brings Goku and Pan to manageable levels of power, Haze Shenron beats up the heroes and throws them into a polluted lake. Unfortunately for him, Giru drags them both to a fresh water geyser, which Goku and Pan blow up to clear the lake of Haze's pollution. With his only advantage gone, the Two-Star Dragon is destroyed when Goku and Pan combine Kamehamehas to blast him into the water
