The Scarlet Book, which will appear in Pokémon Scarlet, and the Violet Book, which will appear in Pokémon Violet, are records from an expedition, and they were written long, long ago. The expedition is said to have traversed an uncharted area of the Paldea region, but whether or not the accounts depicted in the books are true remains unclear. It seems Arven always carries a copy of one of the books with him.
Photographs and sketches of unidentified creatures fill the pages of the Scarlet Book and Violet Book. While there have been sightings of similar creatures in recent years, such reports are rare, and specific details of the creatures’ biology are still a mystery.
The Monster Known as Great Tusk
The book describes how this savage monster attacked the expedition team with its large body and tusks, mortally wounding one of the explorers.
The Monster Known as Iron Treads
It is said that when this monster curls its body and rolls to attack, it leaves a trail gouged into the ground, as if it had scorched the earth.
Note: Great Tusk will be depicted in the Scarlet Book, and Iron Treads will be depicted in the Violet Book.
