#14 Kakuna

Height - 2'-00"                     Weight - 22.0lb                     Type - Cocoon

Almost incapable of moving, this Pokémon can only harden its shell to protect itself from predators.

Now here's a worthless Pokémon if I ever saw one.  It just sits around and hardens while it gets beat up.  Luckily this Pokémon only stays like this for a few levels.  It evolves into Beedrill at level 15.
