Bugsy is the 2nd gym leader in the Johto Region in the 2nd generation of Pokemon games (Gold,Silver, Crystal) as the leader of the Azalea Gym. His specializes in bug-type pokemon, which is true to his namesake. Except he is one of the easiest gym leaders in the game. He's only got 3 pokemon, two of which are Metapod and Kakuna which don't have much of an offense. The only thing to worry about is a moderately powerful Scyther who isn't terribly difficult.
