Hitmonlee

While being an offensive hazard remover in a metagame where entry hazard removal in general is limited may seem appealing, Hitmonlee has fatal flaws that prevent it from fulfilling that role to a decent extent. Such flaws include being rather slow at base 87 Speed for such a frail Pokemon, competition from better Fighting-types to use in general, and the inability to beat many entry hazard setters due to the aforementioned low Speed and frailty. Hitmonlee also fails to perform a cleaner role effectively due to its lack of raw power, even with a Liechi Berry, the fact it can only attempt a sweep once per game, and its vulnerability to being revenge killed by any priority moves due to it always attempting to sweep at 1 HP.
