Zubat

Zubat is a small, bat-like Pokemon. It is dual Poison/Flying type. Zubats are very often found in caves, so they are plentiful. They would show up a lot and can very often attack in groups. Zubats are one of the weakest Pokemon, but between their constantly harassing trainers and their Supersonic and Confuse Ray, they are one of the most annoying Pokemon.
