As with SilverAsh and Pramanix, Cliffheart has the traits of a snow leopard (Panthera uncia), two of which can be seen in her Elite 2 artwork.
Her codename refers to her hobby of mountain climbing, while her real name Ensia is derived from the scientific name of the snow leopard (see above). She shares this naming scheme with SilverAsh and Pramanix whose given names are Enciodes and Enya.
Along with Shaw, Rope, FEater and Weedy, Cliffheart has become the subject of a meme within the Arknights community known as "Crownslayer Bully" where the five Operators exploit their push/pull skills to mess up Crownslayer's pathing, especially in 4-4.
Cliffheart is one of the few characters in Arknights who wears revealing clothes (not including outfits), despite coming from the cold and snowy region of Kjerag.
