Arbok

Arbok differentiates itself from other Poison-type wallbreakers in Haunter and Golbat with its strong coverage options, which let it better pressure checks such as Torkoal, Mawile, and Chimecho. Additionally, its solid coverage and power give it an advantageous matchup against common leads like Metang, Flareon, and Hitmonchan and make it difficult to wall. Arbok's also one of the best offensive checks to Hitmonchan and can check other physical attackers like Raticate and Vigoroth in a pinch thanks to Intimidate. However, Arbok still finds itself mostly outclassed by Golbat, whose better typing lets it check foes like Tropius more effectively. Arbok also suffers from being extremely vulnerable to some of the most common Pokemon in the tier, namely Haunter, Chimecho, and Sableye, which hurts its consistency.
