While Abra and his two evolutions are all about Psychic powers, Machop and his followers focus on brute strength. Almost all of their moves are Fighting type, and any stat outside of Attack is fairly low. Keep pushing him, however, and you'll have a seriously strong Pokemon on your hands - just watch out for Flying and Psychic types.
