Genetic engineering in fiction means changing someone’s DNA to give them special abilities, or to make them look or act differently. In stories, this can mean that a scientist might change the DNA of a regular person like you or me, so that they turn into a superhero, monster, or something else. It can also mean that a group of people might play around with the genes of animals to make them bigger, faster, or more intelligent. In either case, genetic engineering is like a super power that can be used to create new and exciting things.
