Makai Senki Disgaea is an anime series based on the video game Disgaea: Hour of Darkness. Makai Senki Disgaea follows the same general plot as the game, but with several alterations to character roles and the chronology of events. The anime was licensed by Geneon Entertainment before closing their doors in 2007. On September 1, 2010, North American anime distributor Funimation Entertainment announced that they have rescued the series and will release the complete series in 2011.
A bonus feature on the DVD of Disgaea 2: Cursed Memories was a trailer of what the Disgaea anime would look like. The trailer showed mainly scenes from episode 1 of the game where Laharl is awakened by Etna and he challenges Mid Boss in his castle. Also shown were Flonne’s descent into the Netherworld, Gordon piloting his ship through space, and a peculiar battle between Laharl and Baal. However, the anime turned out to be completely different from what was shown in the trailer. No explanation was given for the drastic departure of the final anime from the trailer. A preview of the Disgaea anime was also available on another Geneon anime DVD, Hellsing Ultimate OVA I.
