Koga (Japanese: キョウ Kyō) is a Trainer card. It is part of the Gym Challenge expansion.
| If an attack from a Pokémon with Koga in its name does damage to a Defending Pokémon this turn, that Pokémon is then Poisoned.
This card was included in the Gym Challenge expansion as both a Holofoil and Non Holofoil card. The Non Holofoil print was first released in the Japanese Challenge from the Darkness expansion.
Koga is one of the Gym Leaders of the Kanto region.
