As a Pokémon enthusiast and a self-proclaimed expert in Pokémon games, I'm thrilled to help you out with your question about obtaining Heatran in Pokémon Platinum.

In Pokémon Platinum, Heatran is an elusive and powerful Fire/Steel type Pokémon that can be found in the Stark Mountain area. Here's a step-by-step guide on how to catch it:


1. Travel to Stark Mountain: Heatran resides in the volcanic Stark Mountain, which is located to the east of Oreburgh City.


2. Access the Mountain: You'll need to go through a series of events in the game before you can access the mountain. This includes defeating the Oreburgh Gym and obtaining the Mach Bike.


3. Navigate the Caverns: Once inside, navigate through the volcanic caverns until you reach the area where you can see the magma.


4. Use the Mach Bike: There will be a specific area where you need to use the Mach Bike to cross a narrow path over the magma. This is a crucial part of the process.


5. Find the Legendary Pokémon: After crossing, you'll encounter Regigigas. You do not need to battle or catch Regigigas to find Heatran.


6. Search for Heatran: Continue exploring the area. Heatran can be found roaming around in the caverns. It's important to note that Heatran will flee from battle if it takes enough damage, so be careful not to let it get away.

7.
Catch Heatran: Once you encounter Heatran, use your best Pokémon to weaken it without knocking it out. Then, throw a Poké Ball to try and catch it. You might need to use multiple Poké Balls or even some status effects like sleep or paralysis to increase your chances.

Remember, Heatran is a rare and valuable Pokémon, so be patient and persistent in your search.
