Released in 1999 as part of the original Pokémon Base Set, this 1st Edition Porygon card is a classic piece of Pokémon TCG history. The card’s bright polygonal artwork by illustrator Tomoaki Imakuni highlights Porygon’s identity as a “Virtual Pokémon” against a simple stylized background of green mountains and trees. A small star in the lower right corner marks it as a Rare Base Set card, and the 1st Edition stamp shows its collectible status. Its **Conversion** moves let players change the Defending Pokémon’s weakness type or Porygon’s resistance, offering an interesting twist in early Pokémon battles. Collectors will appreciate the nostalgic Base Set design and 1st Edition stamp on this vintage Pokémon trading card.
