Medicham

At first glance, Medicham might look like a mediocre Pokemon. It only has base 60 attacking stats, as well as a rather average base 80 Speed. However, Medicham has an ability that makes it different from other Fighting-type Pokemon: Pure Power. Pure Power raises Medicham's attacking power to insane levels, and with a great offensive typing and coverage options, Medicham makes a great physical attacker. Another merit that separates Medicham from other Fighting-type Pokemon is that it is resistant to Fighting-type attacks due to its Psychic typing, making for a decent check to other Fighting-type Pokemon. Medicham is also the only Fighting-type Pokemon other than Gallade to receive Trick, and with such offensive capability, it can use Choice items to great effect. However, Pure Power isn't enough to make Medicham unbeatable; 65 / 75 / 75 defenses aren't helping Medicham take many hits. To add to Medicham's flaws, base 80 Speed is only average, making it slower than Pokemon such as Hydreigon and Latios, both of which can OHKO Medicham. The fact that its only STAB priority attack, Vacuum Wave, is specially based is another flaw in Medicham's resume. However, Medicham is a Pokemon that has all the tools it needs to succeed, so not preparing for it will cause grief for your team.
