Haze Shenron

Haze Shenron is the Two-Star Shadow Dragon, born from the negative energy of the wish to resurrect everyone killed by Vegeta and Nappa during the Saiyan Saga. The weakest of the seven Shadow Dragons individually, he compensates through environmental warfare — emitting toxic pollution that weakens the bodies and ki of all living creatures nearby. He turned an entire ecosystem into a poisoned wasteland in Dragon Ball GT, requiring Pan to find a creative solution to stop the environmental damage rather than just defeat Haze Shenron directly.
