the virus in rise of the planet of the apes
Rise of the Planet of the Apes After attempting to test the drug on a scarred bonobo test subject named Koba, Franklin becomes exposed to ALZ-113 and becomes ill. Attempting to warn Will at his home, he sneezes blood onto Hunsiker and is later discovered dead. Will attempts to reclaim Caesar, but the chimp refuses to go home with him so he could look after the other apes. Instead, he escapes from the facility and returns to Will's house, where he takes canisters of the ALZ-113. Upon returning, Caesar releases the gas and allows it to enhance the intelligence of the other apes. When Dodge attempts to get him back into his cage, Caesar speaks for the first time, yelling "No!" and gets in a fight which inadvertently leads to Dodge's death. The apes flee the facility, release the remaining chimps from Gen-Sys, and free more apes from the San Francisco Zoo on the way.
