Cianwood City Pokémon Gym Leader: Chuck
His Roaring Fists
Do the Talking
In Pokémon Gold, Silver, and Crystal, the player has to face three Gym Trainers before reaching a boulder puzzle that is blocking the path. After solving the puzzle with a Pokémon knowing Strength, the player will battle one more Gym Trainer, clearing the way to the Gym Leader Chuck. Before the match, Chuck will demonstrate his physical strength by throwing aside the boulder besides him, after which he will agree to battle the player.
After Chuck has been defeated, his wife will give the player HM02 (Fly) if talked to outside of the Gym.

His Roaring Fists Do the Talking
In Pokémon HeartGold and SoulSilver, the layout of the Gym has changed drastically. The player will be able to easily reach Chuck, but since he's training under a raging waterfall, he doesn't seem to notice the player. Therefore the player must climb up stairs to the top of the Gym to turn a large winch to stop the waterfall. On the way to the winch, the player is forced to face at least one of the Gym Trainers. After turning the winch, the player can return down to face Chuck, who will now accept the challenge to battle.
Much like in Generation II, Chuck wife will give the player HM02 (Fly) after noticing their Storm Badge.
Trainers with a telephone symbol by their names will give their Pokégear number to the player, and may call or be called for a rematch with higher-level Pokémon.

The Cianwood Gym made its first and only appearance in Machoke, Machoke Man!, in which Ash challenged Chuck in order to win his fifth Johto Gym Badge. Ash's first Pokémon was Pikachu, which he sent to battle against Chuck's Poliwrath. Despite the type advantage, Pikachu was eventually defeated, although not before dealing some damage on the Tadpole Pokémon. Ash's next Pokémon was Bayleef, which defeated Poliwrath and proceeded to take on Chuck's Machoke. After a hard-fought battle, Bayleef emerged victorious, earning Ash the Storm Badge.
In the anime, the Gym also appears to be the home of Chuck and his wife.
Trivia
In the games, the Cianwood Gym, the Blackthorn Gym, and the Celadon Gym are the only Gyms that require the use of an HM, as part of a Gym puzzle, in order to progress. Cianwood and Blackthorn's Gyms require Strength in Generation II, while Celadon's requires Cut in all Generations except Generation II.
The Gym guide for the Cianwood Gym is inside the local Pokémon Center rather than the Gym itself, apparently because the Gym Trainers are too uncivilized.
The Veilstone Gym and the Cianwood Gym share the outlook of the Gym in the anime.
