So any predictions on what Typhlosion's Unrivaled Tera type will be. I know there was a "leak" that said it would be Dark but that leak was wrong about the date, also unless they plan on giving Typhlosion new move before the DLC, it doesn't even have any dark moves to use. However there is a theory floating around the the PLA starters intentionally have Tera types to be super-effective against their Hisuain forms
Also, it's safe to assume that it will not be Fire (Typhlosion is already Fire), nor will it be any types that the other starters have gotten in their Tera Raid.
Grass seems to be likely due to Flash Fire canceling Grass's weakness.
