Kella Ser are generally sleek and stand at an average of three feet — not including their ears — though variations in body type and height are not uncommon. They are mostly covered in fur, which may vary in length and texture between each individual.
Their ears come in many different sizes, shapes, and styles, though most of them have pointed tips. However, rounded tips, folded ears, and other variations do exist!
These creatures' watchful eyes always have pupils that are pointed in shape. The number of points may vary, as can the overall shape of their eye.
Other than fur, scales also have a place on a Kella Ser's body. Scale placement always starts at their neck and ends at...their other neck. They vary in style, but are always a different texture than their fur. It is believed that they evolved this way to protect an otherwise soft underbelly.
Kella Ser are both quadrupedal and bipedal, though some prefer one method of travel over the other and may stick to that one. As a result, their paws may develop differently, such as becoming larger and more dexterous to be able to hold objects while standing on two. However, this kind of growth is not consistent, as big forepaws may also be present on those who prefer to walk on all fours.
Their tails take after serpents in appearance. All Kella Ser must have a tail, though those with more than one also exist. In the event of an accident in which their tail is somehow damaged or removed, they can still survive. However, these injuries may result in mental damage, since the two heads are so closely linked.
