Burgh, the Castelia City Gym Leader, specializes in Bug-type Pokémon. His ace is a Leavanny. Fire, Flying, and Rock-type moves are super effective against Bug-types. Consider catching a Darumaka on Route 4 or training a Pidove. The Gym puzzle involves navigating through cocoons. Defeat Burgh to earn the Insect Badge and TM76, Struggle Bug.
