If you are talking of the fastest Pokemon, then it has to be Crobat. This was the first Pokemon that was a fierce battler and a competitive one at that too. The Crobat Pokemon, as any Pokemon fan would know, makes for a dependable option when poison and speed are the need of the hour. Of course, where these two characteristics are concerned, the Zubat, a fully evolved one at that, is the best choice, although these might not be able to sweep off any teams. Shaped like a bat, the Crobat certainly have a mean appearance that well-reflects their aggressive personas.
