Lien-Da is a mobian echidna whose design has changed several times over the years. However, she is almost always depicted as having red fur and hair, blue eyes, a peach muzzle, and a black nose.

Lien-Da's wardrobe originally consisted of a black leather jacket and matching trousers, but it later changed to become tighter trousers with frayed cuffs and a black crop top shirt.

The long sleeves of the shirt have a gleaming silver snake design on them, and she has a tight black pants.
