Byron is Canalave’s Steel-type specialist and Roark’s father. His interest in mining complements a team built around resilience.

Story: He is the sixth Gym Leader. After the battle, the Canalave Library meeting advances the investigation into Sinnoh’s lakes.
In the game: First Gym battle in Platinum: Magneton Lv. 37; Steelix Lv. 38; Bastiodon Lv. 41. Ground and Fighting attacks can break through his defences.
Gym puzzle: Navigate the lifts between floors to reach the elevated platform where Byron waits.
Rewards: Win the Mine Badge and TM91 Flash Cannon. The badge allows Strength outside battle once you have the HM. These are the first Gym teams, not the later Battleground rematches.
