He is a Duel Monster spirit of "Cliff the Trap Remover" brought to life by the power of the Shadow Charm. He is also the member of the band of thieves known as the Dark Scorpion Gang (Black Scorpion Graverobber Gang; 黒サソリ盗掘団, Kurosasori Tōkutsu-dan), who were also brought to life by the item. He masquerades as a security guard named Mr. Cliff (the "Mr." is omitted in the dub). However, since they fail to obtain the keys in a Duel, they are unable to unlock the spirit gate of the Sacred Beasts. When Zaloog and his gang are discovered, he and Chazz Princeton Duel with all the remaining keys on the line. In the end, he and his cohorts are defeated, and the power of his Shadow Charm is nullified. After reverting back to their spirit forms, the Dark Scorpions join the many weak monsters in Chazz's care, to the young Duelist's annoyance. He never uses them however, and they haven't been seen since.
