Hitmonchan

In a tier filled with many viable Fighting-type Pokemon, Hitmonchan struggles to stand out. Hitmonchan often finds itself weaker, slower, or frailer than other Fighting-types, and in some cases all three. It is also flawed as a Rapid Spin user, as it cannot handle spinblockers very well unlike the usually superior option, Kabutops. Hitmonchan also doesn't have any tricks up its sleeve to get past Psychic- and Ghost-types like some other Fighting-types; with these things in mind, it might seem like Hitmonchan has nothing going for it.

Despite generally lacking in stats, and to an extent in movepool, Hitmonchan does have a small niche provided by Iron Fist. It has access to a very wide array of punching moves, including the rare Mach Punch and the elemental punches, a trait only shared by Gurdurr. Due to this, its coverage moves hit harder than its competition, and Mach Punch, a move most other Fighting-types lack, can revenge kill a large number of threats, especially those that are weak to it. Overall, always consider your other options before using Hitmonchan, but don't discount it completely, as it might be just what you are looking for.
