Zombies are resurrected human corpses that appeared in FBI Warning of Doom. Sergeant Slab Rankle created an army of them from the rule-breakers he captured over the years, presumably via the "new zombie lab" that had recently been set up in the back of the mall.
Rankle ultimately unleashed this zombie army as a last-resort effort to stop Zim from returning GIR's movie rental, Intestines of War, to the Video Outhouse. Though they were sent out in large numbers, they were literally brainless, and did little more than shamble around, their feeble attempts to apprehend Zim hardly hindering him from reaching the video deposit slot.
As far as appearances go, Rankle's zombies are not as gruesome as other zombies, but some have an eye missing.
Some zombies are wearing the same uniform as Slab Rankle, suggesting that they used to be security guards, but were fired.
