Smok(スモーク; Sumōku), known as the Wawel Dragon(ヴァヴェル・ドラゴン; Vu~avu~eru doragon) or the Crazy Bones Dragon(狂骨龍; Kyō-kotsu ryū), was an Evil Dragon whose main abilities consisted in consuming his foes and adquiring their abilities, making him the main enemy of Zirnitra. He was killed by the hero Skuba, but his soul still lingers around the world. One of the main and primal objectives of the Weiß team is to find and destroy the remainings of his soul before he can reincarnate.
