In today’s Pokémon Presents video presentation, two new Paradox Pokémon were introduced and are now available in Pokémon Scarlet & Violet: Walking Wake and Iron Leaves.
Walking Wake is exclusive to Pokémon Scarlet and resembles a prehistoric Suicune. It’s a Water/Dragon-type Pokémon.
Iron Leaves is exclusive to Pokémon Violet and resembles a robotic Virizion. It is a Grass/Psychic-type Pokémon.
These two Pokémon are available in special Event Tera Raids until March 12, and require Scarlet or Violet to be updated to version 1.2.0, which is now available. They are available in 5-star Raids and you can only catch one of each per game (at least through these Tera Raids; they may be made available in the future), plus these ones are not available in Shiny form, so don’t worry about Shiny hunting for them.
