Stores up electricity in its body, then suddenly releases it to surprise and shock everyone.
This card was included as a Secret card in the Team Rocket expansion, having been made especially for the English set by Wizards of the Coast. It was later printed as a Super Rare in the Japanese Crossing the Ruins... expansion. The text in the top-right corner of the card reads "Put Raichu on the Basic Pokémon", as opposed to the proper "Put Dark Raichu on the Basic Pokémon". It was reprinted in the Legendary Collection expansion with the text corrected. An exclusive Non Holofoil print was included in the TurmoilTheme Deck. The interior of this card's evolution box is light gray, not dark gray, as opposed to other Dark Pokémon from the Team Rocket set. It appears this way even on the Legendary Collection print.
This card was the first Secret card in a TCG expansion. It was also the first card that was released internationally before it was released in Japan.
This card caused the Team Rocket expansion to be delayed, due to Dark Raichu needing to be approved by Nintendo.
