Lucky

Lucky was a chimpanzee held at the San Bruno Primate Shelter with Caesar. When testing of Dr. Will Rodman's new "ALZ-113" drug began at Gen-Sys Laboratories on an initial ten chimpanzee test subjects (which included Koba), further chimpanzees were acquired from the San Bruno Primate Shelter, including Lucky and - later still - Cornelia. Their eventual fate is unknown, although it is likely they were still alive when Caesar freed the lab apes.
