The Two-Star Dragon

Goku, Pan, and Giru confront Haze Shenron near a polluted lake. The two-star dragon insists he is the strongest of the seven Shadow Dragons, but Pan treats him like a punching bag, sending him bouncing off cliffs and craters. He boasts that transformations are for cowards and that a truly powerful warrior does not need them. Pan demands the Dragon Ball after each beating, but Haze keeps insisting the real fight has not started.

Goku compares the dragon to Mr. Satan, noting the massive gap in power. But something strange begins happening. Pan grows increasingly tired while Haze does not even break a sweat. Suddenly, the dragon can block Pan's punches and even land blows of his own on both Saiyans.

Haze Shenron reveals his true ability: his body radiates negative energy that turns water into poison and drains life force from the surrounding environment. Pan and Goku are not losing because Haze is strong; they are weakening because the entire area is toxic. Goku cannot even transform into a Super Saiyan. The dragon says he is simply accelerating what humans have already been doing to the planet.

Haze explains his origin: he was born from the negative energy of Goku's wish to revive Upa's father, Bora, years ago. The dragon uses Pan as a bowling ball, rolls her into Goku, and fires a mouth blast at them both. When Giru tries to intervene, Haze smacks the robot into the lake and tosses the Saiyans in after him.

Submerged in the poisoned lake, Pan calls out for anyone to save them. Instead, Giru drags both of them to an area of clean water fed by an underground spring. The pure water instantly restores their strength, and Pan comes up with the idea of riding the spring current to the surface using a Kamehameha for momentum.

Above the lake, Haze Shenron celebrates, dreaming of covering the entire planet in his pollution. Goku and Pan burst out behind him, fully restored. Before the terrified dragon can reach the lake, they fire a combined Kamehameha that disintegrates him completely. The cracked Two-Star Ball heals itself, turning orange and whole again. One dragon down, six to go.
