1999 Pokemon Base Set Dewgong - 1st Edition #25
Release information - This card was included in the Base Set, first released in the Japanese Expansion Pack. It was reprinted in the Base Set 2 and Legendary Collection expansions.
Trivia - Aurora Beam and Ice Beam are both moves in the Pokémon games that Dewgong can learn. This card's English Pokédex entry comes from Pokémon Red and Blue, whereas the Japanese entry comes from Pokémon Red and Green.
Information - Base Set is the name given to the first main expansion of the Pokémon Trading Card Game. In Japan, it was released as Expansion Pack, the first expansion in the Pokémon Card Game. It is based on Pokémon Red, Blue, and Green, featuring Generation I Pokémon. The English expansion was released on January 9, 1999, while the Japanese expansion was released on October 20, 1996. Although not part of the TCG, Bandai Pokemon Cards Part 1 Green & Part 2 Red (September 1996) is regarded as pre-dating the Japanese Base set, and therefore is the oldest known Pokemon Card release.
