Beastkin
Source Pathfinder Lost Omens: Ancestry Guide
The blood of a beast flows through your veins, granting you the ferocity and might of animals. Only creatures with the humanoid trait can take the beastkin versatile heritage. Choose a type of animal such as bat, eagle, shark, spider, tyrannosaurus, wasp, or wolf. This is the type of animal tied to your heritage and is known as your inherent animal. A beastkin's hybrid form is their natural shape. You gain the beast and beastkin traits, in addition to the traits from your ancestry.
You gain the Change Shape (Beastkin) ability. You can choose from beastkin feats and feats from your ancestry whenever you gain an ancestry feat.
