* This card was first used in the [[Yu-Gi-Oh! - Duel 037|DEATH-T Duel]] of the [[original Yu-Gi-Oh! (manga)|manga]] and [[Yu-Gi-Oh! First Series - Episode 024|first series Toei anime]].

:[[Kaiba]] used this card on his "[[Saggi the Dark Clown]]", whose [[ATK]] raised from 600 to 1800. It destroyed [[Yugi]]'s "[[Winged Dragon, Guardian of the Fortress 1|Winged Dragon, Guardian of the Fortress #1]]", and several other monsters. * The first [[Duel]] of the [[second series Yu-Gi-Oh! (anime)|NAS anime]] is based on the DEATH-T Duel. However, by the time this episode was aired in Japan, "[[Dark Energy]]" was already released in the ''[[OCG]]'' with its official effect. To avoid a conflict with the ''OCG'', "[[Negative Energy Generator]]" was created to replace it.
