Pangoro

Pangoro has a number of desirable traits that make it one of the most threatening wallbreakers in the AAA metagame. Its high Attack stat, unique typing, and great movepool allow it to hit the entire metagame for high damage. Defensively, its typing also grants it a resistance to Rock, allowing it to switch into Stealth Rock multiple times, as well as a 4x resistance to Dark, making it much easier to take Foul Play compared to most other physical attackers. The aforementioned resistances and its Psychic immunity give it many potential switch-in opportunities. Pangoro also has access to Swords Dance, further decreasing the amount of Pokemon that can switch into its attacks and allowing it to tear apart a lot of defensive teams. Despite its great matchup against defensive teams, Pangoro is unfortunately held back by its poor defensive stats and typing, making it vulnerable to a lot of priority moves. That and its lackluster Speed make it struggle to be relevant against more offensively oriented teams. Pangoro also has a lot of competition from other Fighting-types like Lucario and Heracross, which are both faster.
