Where to find Pokémon Violet DLC Paradox Pokémon

Pokémon Scarlet and Violet's DLC added new Paradox Pokémon to the game in the Indigo Disk part of the DLC, two based on Raikou and Entei for Scarlet and two based on Cobalion and Terrakion for Violet.

How to unlock the Paradox Pokémon

The first thing you have to do to make these Pokémon appear is complete Perrin's Quest, including catching the Bloodmoon Beast in Kitakami during the Teal Mask part of the DLC, so you'll have to fill up your Pokédex in both parts, 150 in Kitakami and 200 in the Terarium.

Where to find Iron Crown and Iron Boulder

After having 200 Pokémon registered in the Blueberry Pokédex, Perrin will show you two pictures with hints about these Pokémon locations.

Iron Crown

Iron Crown is Cobalion's counterpart; Perrin's hint leads you to a cave right below where you start when you enter the crater; there is a hole in the ground from where you can enter almost immediately. Iron Crown should be on an exit looking towards Research Station No. 1.

Jump down the hole

Iron Crown

This Pokémon has the moves Sacred Sword, Tachyon Cutter, Future Sight, and Volt Switch; Sacred Sword ignores your stat changes, so even if you raise your Defense, the damage won't be reduced, and Future Sight is a delayed attack, you'll get hit two turns later.

Iron Boulder

Iron Boulder is Terrakion's counterpart, and to find it, you can take a teleporter from the entrance before entering the crater and go to Research Station No. 2; the Pokémon should be right below this station, behind the broken piece of land.

Iron Boulder

This Pokémon has the moves Sacred Sword, Mighty Cleave, Swords Dance, and Megahorn; Mighty Cleave hits you even if you use a protect move, and Swords Dance raises its attack by two stages, multiplying its damage by 2, 3, or 4 depending how many times it used it.
