Servine is a slim bipedal Pokémon that is primarily green with a cream underside, and narrow red eyes. It has a yellow V-shaped structure that starts at the chest and extends behind the shoulders. Servine has short limbs and a small crest protruding from the back of its head. Three palmate leaves grow along its back and tail. These leaves are capable of performing photosynthesis, but only while they are clean. Servine will go to great lengths to stay dirt-free for this reason. This swift Pokémon hides in thick foliage or shadows to avoid attacks before retaliating.
Ken Sugimori has also said that Snivy, Servine, and Serperior are based on Western culture, specifically mentioning the manga series The Rose of Versailles as an inspiration. Additionally, Servine's physical features resemble the acanthus leaf motifs popularized during the Renaissance. Servine, Pignite, and Dewott's evolutionary lines are collectively based on Western, Chinese, and Japanese culture respectively, to represent the diversity of the Unova region.
