The user can transform into beasts, as well as use the abilities, traits and appearance/physiology of beasts by rearranging their own DNA structure. Users may be able to transform into beasts and/or monsters they have never encountered. Some may have this ability from an empty genetic code, allowing them to accept any form from which they have a DNA sample, others may be able to alter their form mentally and change just by seeing and mimicking beastly features.
