He can emit an oneiric mist from his mouth that traps people in a dream state, and he usually eats the dream incarnations of his victims in their dreams, effectively killing them. However, he does spare some of his potential dreaming victims, like Mia and Dayu. Unfortunately, after becoming a little more frightening, he was defeated in the episode "The Ultimate Duel" by Kevin's Hyrdo Bow and then with the Samurai Megazord. He later reappears as a ghost in "Party Monsters" where he is seen amongst the other deceased Nighloks attending their afterlife Halloween party.
