At first it began as a side effect of gene therapy to gain genetic enhancements, such as improved hearing, sight, or agility. The effects of these changes were dependant on how well the body took the gene therapy. In some cases, changes were subtle, such as slightly elongated ears, skin patterns, or mutated pupils; in other cases, it was dramatic-- fur growth, full facial changes, limb mutations, feather growth, scale growth.
The hybrid look soon became a new, popular fashion statement, with people going into gene therapy purely for its aesthetics.
- Animal and plant traits can be applied to humans, insect traits are limited.
- Modifications involving venom, or other lethal defense traits from other animals are highly illegal. Some operations can be found which can provide these modifications offshore, though. Since the procedures aren't provided through Genus, they can be very risky.
- Because of the Humanity Protection Act, there are different classes of Hybrids. Those that fall into C class are no longer allowed to reproduce once they are a hybrid. A person may preserve their ova, or semen before the hybridization procedure begins, if they wish to reproduce.
- The Humanity Protection Act prevents human traits to be applied to animals.
