Machamp

Machamp has a lot of competition as a niche Fighting-type Pokemon in LGPE OU, with Poliwrath providing greater defensive utility thanks to its additional Water typing, Hitmonlee having a more spammable STAB move in High Jump Kick and a better Speed tier, and Primeape providing an effective pivot with its access to U-turn. What Machamp offers is a midground between Poliwrath and Hitmonlee, with very similar bulk to Poliwrath and attacking power similar to Hitmonlee—in fact, its coverage moves hit harder than Hitmonlee's thanks to its superior Attack stat. This extra level of offensive threat compared to Poliwrath makes it better at forcing Mew to switch in and risk taking a Toxic. Its lack of a Water typing also has upsides defensively and notably allows it to trade blows with standard Zapdos and Mega Venusaur far better than Poliwrath can. These traits combine to make Machamp a respectable tank that excels at handling many Pokemon one-on-one and is capable of specifically threatening popular Pokemon like Melmetal, Rhydon, Snorlax, and Alolan Muk. Machamp's main downside is its extremely poor matchup against Mew, which comfortably counters it even when inflicted with Toxic and is on almost every competitive team. Having such a consistent switch-in greatly limits Machamp's ability to perform the damage trades it is used for, but when supported by its teammates against Mew it can still perform respectably.
