Pokemon's First Appearance: Pokemon Red, Blue & Yellow

As a Pokemon heavily dependent on Fighting attacks, Hitmonlee could easily be quite the competitor for Pokemon weak against Fighting attacks. (It also helps that its speed and power is impressive, too.) However, Hitmonlee is very limited in what it can do. Most of its non-damaging and damaging moves are either Fighting or Normal-based, which means it wouldn't last too long against Psychic and Flying-type Pokemon and attacks. (These are Hitmonlee's weaknesses.) Sure, it's either damged normally by other attacks or resistant to them, but Hitmonlee's lack of assorted moves makes it less appealing than other Fighting-based Pokemon. (It has great kicks, though. We'll give it that.)
