Mienfoo - comes late, way too late. He is however quite useful. And you're stuck with a rather slow, averagely strong pokemon with zero bulk for at least 15 levels. He learns a lot of very strong fighting moves, has Bounce for coverage, and U-Turn + (possibly) Regenerator for a very nice niche. Sadly High Jump Kick is not accurate and hurts you a lot if it misses. He's very good vs the whole team plasma, grimsley, also has his uses against Marshal and Iris. I'd rate him higher but his Mienfoo phase is rather weak, and you're stuck with it long enough for it to get on your nerves. Also, Heracross and Scrafty are better choices for a fighting type. Mid.
Nosepass - crashandcortex nailed it perfectly. I have absolutely nothing to add to his analysis, it's spot on. It's on page 20. Low.
Onix - requires trading to evolve and has extremely poor stats other than Defense. Bottom. (T)
Patrat - god save the queen. Bottom. (T)
Pawniard - poor man's Scizor, sort of. Comes right before 7th gym.. where he gets revenge killed by coverage moves. Will probably not evolve until after Marlon. He's ok vs Team Plasma and can do some damage to Shauntal and Caitlin, but high evolution level and low BP both STABs and most TM options bring him down a lot. Low.
Pelipper - arguably the worst water type in the game. Using him was a nightmarish experience. Bottom.
Pidove - very shallow movepool. He's basically stuck with STABs and U-Turn (if you farm BP for it) unless you like shooting Heat Waves off 65 SpA. The "best" part is that he only learns special Flying moves despite being a physical attacker (other than Sky Attack at.. 66), and getting to, say, Fly takes a bit, not to mention Fly kind of sucks. After godly Staraptor in Gen IV this guy is a huge disappointment. Bottom.
