Hitmonchan

Hitmonchan is one of the two reliable Rapid Spin users that exist in NU, with Sandslash being its only notable competition. It's also one of just three fully evolved Fighting-types in the tier, and the only one with access to Mach Punch or Close Combat. These rare traits make Hitmonchan a valuable member of a lot of teams. Outside of those niches, Hitmonchan is a powerful physical attacker with good coverage options in the Iron Fist-boosted elemental punches, but its poor physical bulk and relatively low Speed for an offensive Pokemon make it difficult to switch into battle, and it usually only has room for one coverage move on its sets, making it fairly easy to wall. It also suffers from being mostly outclassed as an attacker by Medicham, which is faster, is nearly 20% more powerful, and has access to useful secondary STAB moves.
