7. Klink
This pokemon really grinds my gears (get it?). While not really very weak, being resistant to most types and immune against poison as all steel types generally are, this pokemon is just… not interesting. It's just a pair of gears that spins around. If they don't spin, they die. At least Magnemite is made of magnets, and magnets are automatically awesome. In addition, they only learn two moves that receive the STAB bonus (Gear Grind and Mirror Shot), and neither is particularly powerful. I suppose Klink just falls into the trap of being a boring pokemon. That may just be me though.
