Bugsy used Kakuna and Metapod against Suicune at the Ruins of Alph. They tried to stop Suicune from moving by wrapping Suicune with Bugsy's net, but it failed.
Near Ecruteak City's Gym, suspecting Silver to be an enemy, Bugsy sent Kakuna and Falkner sent Noctowl to attack him. However, Silver's Weavile easily defeated the two Pokémon. Bugsy and Kakuna were at the Gym when Arceus arrived. Arceus emitted a giant blast that blew Bugsy and Kakuna away, knocking them unconscious. Gold took Bugsy and Kakuna with himself on his Exbo, and went to the Ruins of Alph.
