Biology

Wo-Chien is one of a group of four Legendary Pokémon, alongside Chien-Pao, Ting-Lu, and Chi-Yu, which were trapped in shrines due to their rampage and destruction. Wo-Chien is a snail-like Pokémon composed of a moss-like substance, with a "shell" of numerous wooden tablets on its back.

The tablets are said to contain the misdeeds of the Paldean King from a thousand years ago, with the writer's grudge causing Wo-Chien to be given life. It can drain the life force of plants, leading to areas surrounding it becoming barren of life.
