Dungeon of Doom is the eleventh volume of the Japanese Yu-Gi-Oh! manga and the fourth volume of the English Yu-Gi-Oh! Duelist manga. Both versions are the same aside from number and series name. In the foreword, Kazuki Takahashi mentions that due to a busy schedule, he was unable to design some of the monsters as carefully as he'd have liked to. There was a number of designs he was unsatisfied with. One such example was "Gate Guardian", which he felt he could have made look cooler.
