You're in treble now!

Since sweetsnow73 drew Mirror as a poke leader, I was inspired! I love pokemon, and I love Earth-G, so why not draw something for - Poke-G?
Leader Hamlin runs the Dark gym, which has no lights inside and you have to navigate your way through the gym by the way the BG music increases in volume when you get near a trainer. Hamlin runs the orchestra and makes a lot of music puns. Her main pokemon is a shiny Sableeye called Gobstopper, and the rest of her team comprises of a houndoom, mandibuzz, shiftry, pangoro and sharpedo. When you defeat her, you get the Pitch Badge.
