Card Appearances:Dark Energy

Original Manga Properties:


 * This card was first used in the DEATH-T Duel of the original manga and first series 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, and several other monsters.


 * The first duel of the second series 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.
