Koga's Golbat first made a cameo appearance in That Awful Arbok!, but it wasn't until 15 rounds later that Golbat is seen in action. Koga's Golbat is much smaller than the average Golbat. Its Supersonic can be used to create a magic mirror for scrying to see things from a distance, even if walls or land are in the way. This is shown when Koga uses it to see what is going on in the Pokémon Tower without actually being inside.
After Blue defeated Koga at Silph Co., he stole Golbat to locate Professor Oak. He later returned it to its rightful owner on Cerise Island. At the island however, Koga and Blue were attacked by Agatha, and both are separated. Koga's Golbat ended up with Blue to battle Agatha's Golbat and later her Arbok. After Koga received Golbat again, Koga battled Agatha's Arbok by making use of its Leech Life to suck blood from his body. Koga then told Golbat to spit the blood at Arbok's body, thereby disabling Arbok's ability to change patterns. After knocking out Agatha's Gengar, Blue commanded Golbat to use Confuse Ray to prevent Agatha from escaping into the shadows again.
