Dr. Zin is bald with brown eyes. In his illness, he has unhealthy pale skin with liver spots, and he requires an oxygen tank to help him breathe.


Dr. Zin is ruthless, both with his enemies and with his own people. One of his clones, who is essentially identical to him, gets Rachel Quest killed. He holds Jade Kenyan-Bannon hostage to force her daughter Jessie to manipulate the Quest team for him. When Zin is displeased with his human henchmen, he'll kill them and promote another in their place. Zin holds the entire world hostage with a weather-altering device in an attempt to take it over.
