Steel-types. Poison-types can be hit by Poison moves, but they won't do much damage. Poison moves that serve no purpose other than to poison the opponent won't affect Poison-types, as they can't be poisoned. Extreme Poison, on the other hand, both Steel and Poison are immune to it. Muk's Gas is an Extreme Poison-type move, which is why Magneton and various Poison-types are recommended for Fuchsia Gym.
