Gym Leader: Byron

Type Specialty: Steel
Recommended Level: 38-42
Team:
- Bronzor (Level 37, Steel/Psychic)
- Steelix (Level 38, Steel/Ground)
- Bastiodon (Level 41, Rock/Steel)
Strategy: Byron's Steel-type Pokémon are weak to Fire and Fighting-type moves. Infernape (evolved from Chimchar) will be incredibly effective here. If you don't have a Fire-type, consider a strong Fighting-type like Machamp (evolved from Machoke via trade) or Lucario. Bronzor has Levitate, making it immune to Ground moves. Steelix has high Defense, and Bastiodon has incredibly high Defense and Special Defense. Focus on super-effective attacks and be prepared for a long battle. After defeating Byron, you'll receive the Mine Badge, allowing you to use Strength outside of battle, and TM91 (Flash Cannon).
