KND Z.e.r.o.

Transformation Like Grandfather himself, Senior Citi-zombies can turn other people and animals into their kind through physical contact. They can also rapidly age inanimate objects and structures in to old fashioned objects. Zombification consists of a person's body flashing, with streams of light pouring out of the mouth, eyes, and other parts of the the body. During this process, the person's body rapidly ages. The Senior Citi-Zombies are the secondary antagonists of Operation Z.E.R.O.; they're a form of ancient undead minions created by Grandfather, who can transform humans or animals into them through physical contact. When turned into one, a person becomes extremely old and decrepit to the point of being corpse-like in appearance, with other zombie-like qualities such as yellow eyes and pale/wrinkled skin. In addition, they also become Grandfather's mind-controlled slaves. After Grandfather is decommissioned, every one of the zombies is transformed back into their normal state, thus freeing them from Grandfather's control.
