Zinc is Cobalt's older brother and a member of Alistor's group. He is a troublemaker and a pretty strong physical fighter, but pretty easily scared and even more easily outsmarted. Zinc was previously in charge of Alistor's group before the latter took control of it by beating him in a fight. He is pretty headstrong and stubborn, and won't take no for an answer. He likes to make fun of his little brother for his insecurity and shyness.

Zinc speaks in a loud, powerful, and pointlessly aggressive tone of voice. He sounds and feels like he's constantly trying to start a fight.
