Machamp

Meet Machamp, a Pokemon who has always struck fear into the hearts of those who face it, so much so that it has been OU in some of the past generations, which goes to show how good it really is. Its main selling point nowadays is access to a perfect accuracy Dynamic Punch, thanks to its great ability, No Guard. This, in combination with its massive base 130 Attack, means it is an absolute terror to face in battle. It's not all peaches for Machamp though, as its Speed is pretty low and it only has slightly above average bulk, which means it isn't necessarily built to last. Additionally, Dynamic Punch has a measly 8 PP, which can be gone before you know it during extended battles. That said, if you don't keep this monster in mind when you build your team, you're sure to get absolutely wrecked.
