Players can find and catch Regigigas in Pokémon Brilliant Diamond & Shining Pearl, which debuted back in the original Pokémon Diamond & Pearl. The Sinnoh region is full of legendary Pokémon to discover, and many of them have unique methods to unlock. However, before players can get their hands on Regigigas, they first need to get the National Dex.

Players can obtain the National Dex after seeing every Pokémon within the Sinnoh Dex. After this, speak with Professor Rowan at Sandgem Town, and players will be given the National Dex as a reward. Getting the National Dex also adds a few significant changes to the world, including new areas to explore and new Pokémon spawns. Now that players have access to the National Dex, the next place they need to go to find Regigigas is in Ramanas Park.

Ramanas Park is a new location that players can explore in Pokémon BDSP. It happens to be where Pal Park was in the original games and can be found on Route 221. After the player has completed the Sinnoh Pokédex, new caves will begin to spawn in Ramanas Park. To obtain Regigigas, players will need to find Regirock, Regice, and Registeel within these caves first.

To access these special caves in Ramanas Park, players will need to find special slates. These slates will be placed inside of a pedestal, and a legendary Pokémon will appear as a result. These legendary Pokémon will have Hidden Abilities as well. To get slates, players will need to buy them in exchange for Mysterious Shards within Ramanas Park, and the only way to find this item is by digging in the Grand Underground. Unfortunately, it is entirely random, and players might need to hunt around the Grand Underground for a while to get enough for a slate. To find Regirock, Registeel, and Regice, players will need to get Discovery Slates, which cost 3 Mysterious Shards to create.

After collecting enough Mysterious Shards to purchase the Discovery Slate, place it in the slot at Ramanas Park, and trainers will be teleported to the Discovery Room. Here, players will have access to all three of the Regi Pokémon, and they will all be Level 70. After capturing them all, return to Snowpoint City and enter the Snowpoint Temple in the northern section of town. Head to the bottom floor to find Regigigas as a statue and interact with it using Registeel, Regice, and Regirock to wake it up. It will also be at level 70, and now players just need to capture it using status ailment moves like Thunder Wave or Hypnosis as it increases the chances of capture.
