Haze Shen Long (二星龍, Niseiryū; FUNimation "Haze Shenron"; Literally meaning "Two-Star Dragon") is one of the Evil Dragons.
Haze was the first Evil Dragon to fight against Son Goku and Pan during the Shadow Dragon Saga. He was the Two-Star Dragon and represented 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 he had been killed by Tao Pai Pai.
Physically speaking, Haze was the weakest of the Evil Dragons to the point where Pan was able to completely dominate him by herself. His trump card, however, was the pollution that he caused and made his opponents weaker with time. Therefore, while he remained relatively weak when it came to Scouter readings, his opponents got weaker while he remained the same until his opponents were weaker than him. His pollution had no effect on non-organic beings, however, such as the Machine Mutant Gill.
Haze soon threw Goku and Pan into a polluted lake to die. Gill dragged them both to a fresh water geyser, which was blown up and cleared the polluted lake. He was then destroyed when Goku and Pan combined a blast knocking him into the clean water.
