Mankey

Mankey is a very uncommon, albeit underrated, threat in the LC metagame. This is rather surprising, as Mankey hits hard with an amazing base 80 Attack, and thanks to its high Speed stat, it is also able to Speed tie with many top-tier threats, including Chinchou and Mienfoo. Mankey also has decent abilities in Defiant and Vital Spirit, both of which help it sweep more efficiently when Mankey is matched up against Intimidate users, such as Growlithe, and sleep inducers, such as Shroomish. With these traits, Mankey becomes a powerful revenge killer when holding a Choice Scarf. Mankey can effectively run a Substitute + Encore set as well, thanks to its high Speed stat and Anger Point. Unfortunately, Mankey's defenses are absolutely terrible, meaning that almost any hit can easily take it down. The primary reason why Mankey is rarely seen is because it lives in the shadows of Mienfoo, which has much better bulk, a better ability in Regenerator, a more powerful STAB move in High Jump Kick, and a higher Attack. In fact, the only reasons to use Mankey over Mienfoo are its ability, Vital Spirit, and its access to decent support moves such as Encore.
