The time has come. Ash faces off against Byron in a 3-on-3 battle. Hopefully he'll fair better with Byron than he did with Roark. Will Ash be able to burn away at Byron's defenses, or will Ash get rusty during the battle?
Ash's win against Byron is similar to his win over Jasmine in many ways.
Jasmine's badge (Mineral Badge) was the sixth badge Ash obtained in Johto while Byron's badge (Mine Badge) was the sixth badge Ash obtained in Sinnoh.
Both Byron and Jasmine were defeated in the 108th episode of their region.
Both Gym Leaders specialize in Steel-type Pokemon and also use a Steelix.
Byron's Steelix was defeated by Ash's Chimchar (the Sinnoh Fire-type starter) while Jasmine's Steelix was defeated by Ash's Cyndaquil (the Johto Fire-type starter)
