Darkness Energy (dp3-129) is a Special Energy card from the Secret Wonders set that provides Darkness Energy but is not a basic Energy. It grants the attached Darkness Pokémon's attacks +10 damage to the opponent's Active Pokémon (before Weakness and Resistance) and this bonus is ignored if attached to a non-Darkness Pokémon. Introduced in the Diamond & Pearl Secret Wonders expansion as a Special Energy card.
