Koga’s Ditto (#132) is a holographic rare **Pokémon TCG** trading card from the 1999 Japanese Gym 2 expansion (also called **“Challenge from the Darkness”**). The card’s art by Ken Sugimori depicts Ditto in its classic pink, amorphous form against a swirling holofoil background, complete with a small portrait icon of Gym Leader Koga in the corner. As a Gym Leader variant (colorless-type) from the original Gym series, it carries nostalgic appeal for fans completing vintage Gym-themed decks. Its gameplay—using a coin flip to boost Ditto’s HP—is simple, but collectors prize this card mainly for its shimmering holo pattern and iconic late-’90s artistry.
