Pokémon world locations

Stark Mountain (Japanese: ハードマウンテン Hard Mountain) is a volcano located in the north of the Battle Zone in Sinnoh, at the end of Route 227. It is home to the Legendary Pokémon Heatran, which resides in the innermost chamber. Both Strength and Rock Smash are required to pass through the mountain's caverns.

In Pokémon Diamond and Pearl and Pokémon Brilliant Diamond and Shining Pearl, the player's rival can be found in the entrance chamber, complaining about having been defeated by Buck. Within the main cavern, the player encounters Buck, who is hunting for the Magma Stone and decides to accompany the player to the entrance to Heatran's room. Inside, Buck takes the Magma Stone and leaves.

In Pokémon Platinum, Charon takes control of Team Galactic and travels through Stark Mountain to take the Magma Stone and capture Heatran. Mars and Jupiter are both encountered in the entrance chamber, each battling the player. Within the main cavern, Buck teams up with the player, looking to protect the Magma Stone from Team Galactic. Once the player follows Charon to Heatran's room, Looker arrests Charon and takes the Magma Stone. Buck then returns the Magma Stone after he and the player accompany Looker outside.

After the events at Stark Mountain are completed, if the player speaks to Buck's grandfather in the Survival Area, he will tell them about Heatran. In Diamond and Pearl and its remakes, it is at this point that Buck returns the Magma Stone to its original location. Heatran then appears in its room, ready to be battled by the player.

Geography

Exterior

Stark Mountain's exterior changes between Pokémon Diamond and Pearl and Pokémon Platinum. The road ascends in a huge contour up the mountain and, at that point, Route 227 ends and the exterior of Stark Mountain begins. In Pokémon Diamond and Pearl and its remakes, a huge clearing opens up that contains a large patch of tall grass. The entrance to the interior of the mountain can be found to the west.

In Pokémon Platinum, the exterior is more complex and the path winds around pools of bubbling lava. It is darker and aesthetic features have been enhanced. The large patch of tall grass is still present, but it is not as big. By going northwest, an item can be found in an indented section of track. By traveling to the northeastern corner, a path will open up. By following it, the road will lead through two pools of smoking, bubbling lava around another bend to the entrance of the interior of the mountain.

Partner Trainer

In Pokémon Diamond, Pearl, Brilliant Diamond, and Shining Pearl, Buck can be found inside the main cavern on the player's first visit. He is searching for the Magma Stone and, due to the strong Pokémon in the area, asks to team up with the player.

In Pokémon Platinum, Buck is initially encountered on Route 227 after the player crosses the eastern fallen log. He asks them to investigate a bunch of goons in space suits who are up to no good at the mountain while he returns to the Pokémon Center to heal. After the player enters the main cavern of Stark Mountain, Buck returns and asks to accompany the player.

Buck is one of the Stat Trainers, specializing in the Defense and Special Defense stats. While he is with the player, all wild battles become Double Battles, and all Trainer battles that would otherwise be Double Battles become Multi Battles. After every battle, he will completely heal the player's party. He leaves the player once they have reached the entrance to Heatran's room.
