>Okidogi, Munkidori, and Fezandipiti’s Toxic Chain is a new Ability being introduced in the DLC for Pokémon Scarlet and Pokémon Violet. When one of these three Pokémon hits an opponent with a move, the power of the toxic chain all three Pokémon have may cause the opponent to become badly poisoned.

So then these guys are all Poison type? Their ability is basically a better version of Poison Touch, since it inflicts Toxic instead of regular poison, and works for all attacks, not just ones that make contact.
