In Vermilion City, you'll need to find the Captain of the S.S. Anne to get the HM Cut. After exploring the ship and battling your rival, you can challenge Lt. Surge, the Electric-type Gym Leader. With your third badge, you'll head east through the Rock Tunnel, a dark cave requiring the 'Flash' Secret Technique. Emerge from the tunnel into Lavender Town, a somber place known for its Pokémon Tower.
