Dreadwing (コベルゼブ Koberuzebu, roughly "Little Beelzebu") is a fly-like enemy from Gargoyle's Quest that is first seen in the tower where the Gremlin Stick is kept. It has two varieties. Some crawl walls up and down until they spot Firebrand, leaving the wall and flying horizontally, also passing by walls. Others appear flying back and forth between walls, making it difficult for Firebrand to climb or go down areas with them. Also, Bellzemos can split into four Dreadwings.
Dreadwing's Japanese name appears to be derived from Beelzebub (ベルゼブブ Beruzebubu), a demon who is also known as the "Lord of the Flies".
