Heatran is perhaps the most forgettable Legendary Pokémon in the series, but collectors hoping to complete their Pokédex will be keen to know where to find Heatran, which is what this guide aims to teach you!
Where to Find Heatran in Pokémon BDSP
When you wake up at home after defeating Champion Cynthia and becoming the Pokémon League Champion, your Mom will tell you that your rival wants you to get on a boat to the south of Snowpoint City.
Do so and you will be taken to the “Battle Zone” Island. Just north of the pier where you disembark, you will see two NPCs blocking your way, who will remind you to fill your Sinnoh Pokédex.
Similarly, two NPCs will block your path to the East also, preventing you from exploring Battle Zone island at all until you have completed the Sinnoh Dex.
If you have already done so, and have acquired the National Dex, these NPCs will disappear, and you can freely explore, to follow the post-game story involving an NPC named Buck who is very keen on getting inside Stark Mountain’s Volcanic Cavern.
Battle Zone Island is covered with powerful trainers all itching to battle. Nothing that a Pokémon League Champion can’t handle, though, so feel free to spend some time toughening up your team against them.
However you choose to go about it, make your way to Stark Mountain, on the Northeast side of the island, access via Route 227.
Completing Stark Mountain
Stark Mountain is a dungeon-like labyrinth with boulder-pushing puzzles. Your goal is to reach the center of the volcanic cavern and collect the Magma Stone.
I recommend using the D-Pad to move around in this dungeon as you can very easily push the wrong boulder by accident with , forcing you to leave the area and reset the boulders.
After the first room, you will run into Buck, who will offer to team up with you. With him at your side, he will join you in double battles and keep your team healed after every fight.
High up on the north side of the big chamber where you meet Buck, you will find the entrance to the Magma Stone chamber.
Speak to Buck inside the chamber and then leave Stark Mountain.
Making Heatran Spawn
Go to the “Survival Area” village on the northwest side of the island and enter the house next door to the Pokémon Center.
Note that you can only access this house if you approach this village from the west. To do so, start in the “Fight Area” and head up Route 225 towards “Survival Area”.
Inside the house, speak to the Old Man and Buck, who will go back to return the stone.
Heatran will now be inside the same chamber where you and Buck found the Magma Stone.
Head back inside and use HM Rock Climb to reach the chamber easier now that Buck is not with you.
Heatran will be standing at the back of the oval-shaped ring of boulders in the chamber.
When you find Heatran, interact with it via to begin a battle with it. As with any Pokémon, you will need to weaken it and then try to catch it with a Pokéball.
It is Level 70 and Fire/Steel-type. Its weaknesses are Water, Fighting, and Ground-type attacks. Avoid Ground-type attacks if you don’t want to outright KO Heatran, as they will deal 4x damage.
A good idea would be to save the game before interacting with Heatran. That way, if you see its health drop to zero, you can quickly close the game and load your save back up to try again.
I recommend Dusk Balls which will be extra effective in this dark cave.
If you have kept your Master Ball up to this point, try to save it for roaming Legendaries like Mesprit or Cresselia, rather than using it here.
What If you Accidentally Defeat Heatran?
If you accidentally defeat a Legendary Pokémon like Heatran in Brilliant Diamond or Shining Pearl, you can make them respawn by defeating the Elite Four again.
Be wary, though, for the Elite Four will be much more powerful the second and third time you face them. After the third time, their team and levels will remain fixed.
