The seventh Tera Raid will be a Poison Tera Pokémon.
From Friday January 27 to Sunday January 29, a new Tera Raid Event will begin.
Just like Charizard and Cinderace, only one of this Pokémon will be allowed to be caught per trainer from the Raid. Unlike Charizard and Cinderace though, this Pokémon has not yet been revealed! Its identity is still being kept secret, making some think it could be another starter like Charizard and Cinderace, or that it could be a Legendary Pokémon. It will have the Mightiest Mark upon being caught, making this a sure sign of being a full on event raid.
The announcement for what Pokémon it will be will likely be after the Fighting Tera Cinderace event is finished. With that in mind, this Poison Tera Pokémon will also be something that can make great use out of its Tera Type. Along the lines of starter Pokémon, it could be something like Venusaur that could boost its Poison Type Special Attacks. Or maybe it will be the first Legendary Pokémon in the Tera Raids. Perhaps a Fairy Type that will turn a Poison Weakness into a Poison Resistance by changing its Tera Type. As of now, nothing is for certain, but the announcement is likely to come within the next week or so.
