No, not game. I'm talking about an actual Pokemon. One who doesn't get a lot of attention, but is actually quite awesome.
My nominee: Zubat
Sure, there's tons of them throughout the game. How can such a common (and sometimes annoying) Pokemon be so good? Well, it evolves into Golbat if you put in the effort. Golbat is a pretty solid Pokemon, but it can get even better. Make it happy enough, and then you've got one of the fastest Pokemon in the game, Crobat. I adore Crobat. It's fast, can use Fly, has a decent attack power, and it just looks cool. I never see Crobat get any love, so I'm giving him/her their due. To Zubat/Golbat/Crobat! You are fine Pokemon!
