Z-bands are bracelets that all Zombies are equipped with that sends doses of electromagnetic pulses into the body, keeping the wearers from returning to their former brain-eating state. If the Z-band goes offline, the zombies revert to their brain eating former selves. These bands can be hacked, however, to be not as effective at keeping zombies at a stable sanity level. This is seen on Zed, who uses the hacked band to reveal his stronger heritage for football. Also, any fire, flames, or sparks in the area can interfere with the programming and destabilize the status of wearers. This is seen when Bucky and his squad use sparklers at a pep rally, causing the zombie students to fearfully flee the area for the safety of all. They also have the power to transf a zombie back into a human.
- In the original pilot Zombies & Cheerleaders they were called Z-pads.
