Like most other regions, Sinnoh also has a wide array of Gyms that trainers can battle to obtain badges and to be able to qualify for battle and face the Elite Four. The Sinnoh Gym Leaders are Roark , Gardenia , Maylene , Crasher Wake , Fantina , Byron , Candice , and Volkner . As you can see, the Gym in Eterna, Veilstone, and Hearthome were remodeled and enhanced with new features in from Diamond and Pearl to Platinum . Also in Platinum , some of the Gym Leaders have more powerful Pokémon than in Diamond/Pearl. Sometimes to get stronger in Platinum after you beat the Pokémon League, you can go to the Battle Zone where the Survival Area is to rebattle the Gym Leaders .
