Two brand new Pokémon have been announced for Pokémon Sleep! Onix and Steelix will make their debut soon, and as we learn more about them we will update this article to let you know their Main Skills, berries, and ingredients.

Onix and Steelix will both be able to appear during your Research. They will be available in the Taupe Hollow Research Area. They are both Slumbering Sleep style Pokémon.

Onix and Steelix will be available during Sleep Research from Tuesday, 14th November, 2023, at 15:00.

It is likely that you will need approximately 80 Onix Candy to evolve Onix into Steelix, along with the Metal Coat item. The Metal Coat item has been available in the shop for some time, but wasn’t needed to evolve any Pokémon that were in the game.

It is not currently available as a reward for any of the Medals, but is available to purchase in the Regular Exchange shop for 1400 Sleep Points.
