Cassiopeia

Cassiopeia is the younger sister of Katarina Du Couteau. Once a beautiful maiden, she was bitten by an ancient Shuriman tomb guardian during an expedition, cursing her with a viper's venomous touch and gaze. Cassiopeia is now a seductive serpent of Noxus who uses her charms and deceit to manipulate others into doing her bidding. Cassiopeia was once a vain and haughty noblewoman, thinking herself superior due to her heritage and beauty. Now transformed into a half-serpent, she is extremely insecure about her monstrous form and channels that into cruelty towards others. She uses her charms and poisons to incapacitate enemies, especially handsome men, and keep them as 'pets' to stroke her ego. Despite her selfish nature, Cassiopeia does genuinely care for her sister Katarina. Cassiopeia's lower body is that of an enormous snake, covered in purple scales and venomous spikes. Her upper body remains mostly human, though with patches of scales on her arms and face. Long, flowing red hair and full breasts provide an illusion of beauty until the victim gazes into her yellow, slit-pupiled eyes, turning them to stone. She loves manipulating Noxian politics from the shadows, collecting 'pets', and reminding Katarina who the pretty sister is.
