How do you beat the gym leaders in pokemon platinum?
In order to beat gym leaders you need a wide variety of Pokemon on your team. For the first gym leader, roark, chimchar’s mach punch is a great way to beat him and turtwig and piplup can beat him naturally. For Crasher Wake, later in the game, you can beat him with a croagunk with the ability dry skin. Other than that the other gym leaders should be selfexplanatory and you should always have your pokemon around the level of the gym leader’s.
