Haze Shenron

Haze Shenron is one of the Shadow Dragons in Dragon Ball GT and the dragon of the Two Star Ball.

History
Haze Shenron, like all the other Shadow Dragons, was born from the negative energy of one of the wishes made on the Dragon Balls, in his case the wish that brought back Bora in Dragon Ball.

Goku and Pan first met Haze Shenron when he was attacking a small town. However upon fighting him, the pair found Haze to be extremely weak to the point where Pan was able to fight him alone. But suddenly Haze was able to fight Pan and Goku, who found themselves becoming slowly weaker. The shadow dragon then revealed his secret power, he emitted pollution which was what caused them to become weaker. Haze then showed them a lake he had filled with toxins and when Goku and Pan were too weak to move, tossed them in, along with Giru. However Giru managed to move them to a clean part of the lake, which was kept clean by a fresh water spring. Goku and Pan blasted this spring, sending fresh water everywhere. They confronted Haze again and, when the dragon tried to flee, blasted him with a Kamehameha wave.

Powers
When it comes to physical strength, Haze Shenron is the weakest out of all the Shadow Dragons and even seems to be clumsy, at one point accidentally letting a piece of rubble fall on his foot. His fighting ability comes from his ability to emit pollution, which will weaken his opponents.

Trivia

 * Haze Shenron is similar to Guldo in that they are the weakest of their group and rely on their powers to make their opponents easy to beat.
