Strelac is a form of mutant humans brought on by C-Virus infection. Part of a category of mutations dubbed "Complete Mutations", Strelac are formed when J'avo undergo a process comparable to Virus Activation, where the C-Virus forces in further mutations. Strelac emerges from cocoons with entirely new bodies unrecognizable as human. Their name is the Serbo-Croatian word for "shooter" while "Strela" means "Arrow".[1]
