Diamond and Pearl: the Sinnoh journey
Choose a starter and follow the original Diamond/Pearl badge route from Twinleaf Town to Cynthia.
Original Pokémon Diamond and Pokémon Pearl for Nintendo DS (2006). Generation IV rules, the original 151-entry Sinnoh Pokédex and the Diamond/Pearl Gym and League teams. Platinum, Brilliant Diamond and Shining Pearl have separate game data.
Choose your first partner
After the encounter near Lake Verity, choose Turtwig (Grass), Chimchar (Fire) or Piplup (Water). Turtwig evolves at levels 18 and 32, Chimchar at 14 and 36, and Piplup at 16 and 36. Their final forms are Grass/Ground Torterra, Fire/Fighting Infernape and Water/Steel Empoleon. Barry chooses the starter with the type advantage over yours. Add complementary teammates rather than relying on the starter for every matchup.
The original eight-badge route
The usual badge route is Oreburgh → Eterna → Veilstone → Pastoria → Hearthome → Canalave → Snowpoint → Sunyshore. Maylene and Crasher Wake can be challenged in either order once their towns are accessible. Fantina is the fifth badge challenge in this pair. Open the Gym Leaders reference for the original teams, badge field actions and TM rewards.
Team Galactic and the summit
Clear Team Galactic’s Eterna building, recover the stolen Pokédex near Veilstone and continue the lake storyline after Canalave. The crisis leads through Galactic headquarters to Mt. Coronet and Spear Pillar. Diamond features Dialga; Pearl features Palkia. Save before interacting with a stationary legendary and bring enough catching supplies.
The League challenge
After eight badges, obtain and use Waterfall to travel north through Route 223. Victory Road leads to the Pokémon League. Face Aaron, Bertha, Flint and Lucian, then Cynthia. Review levels, moves and recovery supplies before entering; opponents are not restricted to a single type.
After the Hall of Fame
Visit the Battle Zone and work toward the National Pokédex. The original games have a Battle Tower rather than Platinum’s Battle Frontier facilities. Seeing the required Sinnoh species and owning a collection are different objectives; use the Pokédex and collection guide to plan the next step.
Check the next opponent’s actual roster. Flint and Volkner include several Pokémon outside their advertised type.
