All Pokémon games have version exclusives. It’s a constant attempt to make their players socialize and interact with each other. The new Sword and Shield DLC, the Isle of Armor, added 105 Pokémon from previous generations to the new game. Some of these are exclusive to the different versions. There are only four version exclusive Pokémon in the Isle of Armor DLC.
Sword exclusive Pokémon
Clawncher is the Howtizer Pokémon introduced in Generation Six. It evolves at level 37 into Clawitzer. Both are Water type Pokémon with high Special Attack.
The Water type Clawncher can be found in the Isle of Armor in the Workout Sea, Insular Sea, Stepping-Stone Sea, and Honeycalm Sea. They can also be found at Honeycalm Island.
