Beedrill is a Bug/poison Pokemon and the final form of Weedle. Beedrill is a very fast and dangerous Pokemon, because it can flap it's wings faster then the speed of sound; and it's barbs can inject a dangerous poison. Beedrill is found in the forest area of most maps, and it always travels in a swarm. In the anime a Beedrill attacked Ash but he was saved by his evolving metapod. Ash also caught a Beedrill but he gave it to Casey.
