Dugld (Japanese: デュグルド Romaji: dyugurudo) is a character from the Slayers novel Vezendi's Shadow and the anime Slayers EVOLUTION-R, a low-ranking mazoku in the service of Chaos Dragon Garv. It has the appearance of a man in a black mantle and a wide-brimmed hat. Its face is jet-black and lacks any features. His Japanese voice actor is 平田広明 Hiroaki Hirata.
In the novels, Dugld and Gduza attack Lina Inverse and her friends in Vezendi under the direction of Seigram, who has by that time merged with Zuuma. Dugld fights primarily by using its magic to create black pebbles which it fires at his enemy; however, it also demonstrates several other techniques, such as animating its shadow and creating a sword of darkness. Dugld fights Zelgadiss Graywords twice. The first fight is inconclusive, as the mazoku are forced to retreat when Lina uses Flow Break to dispel the subspace they are fighting in. In their second battle, Zelgadiss clearly has the upper hand, severely damaging Dugld through a combination of a broadsword enhanced by Astral Vine and numerous daggers which he had enchanted previously. Dugld begins destroying its own allies in order to feed on miasma from them, striking down first a lesser demon and then Gduza. However, it is unable to gather enough strength in this manner, and Zelgadiss quickly finishes it off.
In the anime, Dugld serves Zuuma directly, as both Seigram and Garv have been destroyed by the time of its appearance. In his final fight, Zuuma absorbs both Gduza and Dugld into his arms to increase his own power. After consuming them, he gains the ability to launch attacks similar to Dugld's pebbles and Gduza's hair from his arms.
