Pangoro

Due to Pangoro's insane Attack stat, coverage, and STAB attacks, it has paved itself a path to being one of the scariest wallbreakers in the tier. Pangoro can utilize a Choice Band set, making it an even more powerful wallbreaker. In addition to this, Pangoro has access to Swords Dance, which can destroy teams that rely on passive cores such as Registeel + Slowbro if all of its checks have been removed from the field. However, it suffers from a fairly low Speed stat and poor defensive typing, which makes it revenge killed easily. Due to this, Defensive Pokemon such as Florges and Mandibuzz can neutralize it with enough Speed creep. In addition to Pangoro's Speed stat, it's typing gives it a weakness to Fairy-types, Flying-types, and Fighting-types such as Florges, Noivern, and Virizion, which are all very prominent in the tier. Furthermore, Pangoro has fierce competition with the plethora of other Fighting-types in the tier, including Virizion, Bewear, and Passimian, all of which either have better Speed tiers, reliable recovery, or better natural bulk. Due to this, finding a spot to fit Pangoro on a team is difficult, which ultimately results in its lack of usage. Although all of the former is true, Pangoro is extremely difficult to pivot around which makes it a valid option as a Fighting-type.
