Then Brycen is part of the E4. lol my mistakeBurgh is gym leader http://pokebeach.com/
Scroll down to gym leader article cover and look below Skyla. Brycen however isn't there and has only made an appearance in PokeWood.
But to the person whose saying he's third gym leader I hope you realize how stupid that assumption is right now without any gym leader order known other than 1st and second (Cheren, the Homika).
