After his Metapod got defeated, Bugsy sent Scyther in the gym battle against Ash's Pikachu. While Pikachu used Agility, Scyther used Double Team. Pikachu banished some of the illusions with Thunderbolt, but got defeated by Scyther's Fury Cutter. Against Cyndaquil, Scyther used Fury Cutter, but Cyndaquil evaded the attack. Instead, Scyther used Double Team to baffle Cyndaquil, then used Fury Cutter. Cyndaquil avoided the attack and fired Flamethrower, which burned through Scyther's Double Team. However, Scyther spinned around and used Swords Dance to raise its attack power and deflect Cyndaquil's Flamethrower at the same time. Ash saw Bugsy made a strategy to counter Fire-type attacks; Scyther attacked with Fury Cutter, but used Swords Dance to deflect Cyndaquil's attack. However, Cyndaquil jumped above Scyther and spinned while using Flamethrower; Scyther took severe damage from the unexpected technique and Cyndaquil finished it with a Tackle attack.
Bugsy, along with Scyther, appeared in the opening scene of Pokémon: Johto League Champions.
When Team Rocket stole Ash's badges, the latter was searching for them. He also remembered his battles with the Johto Gym Leaders, including Bugsy and his Scyther, as Ash and his Pokémon won those badges with hard effort.
