Storm Emperor, known as Dragon and Kaminari to Tomo ni Arawareru Mono (雷鳴と共に現る者, roughly translated as "It who appears with thunder") in Japan, Tiamat in certain European translations, and Klanvaline in Etrian Odyssey II, is a long, three-eyed draconic serpent which closely resembles oriental dragons and enjoys soaring stormy skies. It has four clawed legs that it probably only uses to attack, as its body is always levitating. It also sports long, red whiskers, a pair of blade-like horns, and a trident-like tail, all of these most likely used to capture and control lightning.
