To beat the Vermilion Gym in Pokémon games, you'll need to prepare for Electric-type Pokémon, primarily using Ground-type Pokémon since they are immune to Electric attacks. Stock up on healing items and consider using Pokémon with strong Ground-type moves, like Dig or Earthquake. Make sure to navigate through the gym's puzzles, which often involve finding switches to open the path to the Gym Leader, Lieutenant Surge. Defeating him will earn you the Thunder Badge and the ability to use the move Fly outside of battle.
