Raticate

Rati-who? Yeah... you know all those annoying rats that attack you in the grass of RBY and GSC? This is the evolution of those things. I will admit, Raticate sees almost zero playing time because it's quite frankly not all that good. Its typing is not unique (in fact it is one of the most common), all of its stats are really subpar or borderline average, and its movepool isn't exactly something to drool over when compared to others on Pokemon with better stats. However, there is hope for this cool-looking rodent yet. Super Fang puts huge dents all over the place, which is hard to do with UU teams that go up against OU teams. Raticate makes a decent UU lead with its Speed, and it can steal fun stuff like Spikes and Sleep Powder with Mimic. It's definitely not the best Normal-type of the bunch, but it is somewhat cool and usually very unexpected. Plus it can always wave around the fact that it can 2HKO Blissey.
