Latios

With the help of Soul Dew, which boosts its Special Attack and Special Defense, Latios is a fearsome special wallbreaker that is able to fire off extremely powerful Draco Meteors. Additionally, its typing and ability give it key resistances to Fire and Water as well as an immunity to Ground, allowing it to serve as a decent check to dominant metagame threats such as Primal Kyogre and Primal Groudon. Latios also has a good base 110 Speed and a movepool including numerous coverage options and Defog, allowing it to wallbreak effectively and provide hazard control for its team. However, Latios's typing leaves it weak to many common attacking types, such as Fairy, Dragon, Ghost, Dark, and Ice. Latios is also vulnerable to Pursuit users, which can eliminate it with relative ease.
