Koga sent his Koffing to battle alongside Blue's Golduck. However, both were knocked out by Agatha's Gengar. Seeing Gengar's shadow was moving, Koffing used Poison Gas to notify Blue about the attack. Due to this, Gengar was lured into attacking a discarded tail of Koga's Arbok, allowing Blue to defeat Gengar with his Blue's Porygon2's Psybeam.
