Darkness Energy is an Energy card. It is listed as Special.
Darkness Energy sits at 104/111 in Neo Genesis, position 104 of 111. Before it is 103 Super Rod, and after it is 105 Recycle Energy. The set belongs to the Neo series. It was released on 16 December 2000. The printed size is 111, and the checklist is the same length. The listed rarity is Rare.
The card text says: If the Pokémon Darkness Energy is attached to damages the Defending Pokémon (after applying Weakness and Resistance), the attack does 10 more damage to the Defending Pokémon. At the end of every turn, put 1 damage counter on the Pokémon Darkness Energy is attached to, unless it's Darkness or has Dark in its name. Darkness Energy provides Darkness Energy. (Doesn't count as a basic Energy card.)
The illustrator line reads Milky Isobe. I count 22 other cards in the catalog with that illustrator.
Neo Genesis set binder is where a full Neo Genesis set goes. This card fills one slot there. I still need this card.
