Kakuna

Biology
Kakuna has a very soft body, which makes them hide in a very hard shell upon evolution. Their shell is so hard that they automaticly improve a move called Harden, which makes them defensively stronger in the battle. However, because of their shell they hide in, they move very hardly and slowly. They are so shieldless and nonprotected in that form that, most of the species hide in the forests to prevent encountering a trainer, which makes them very rare to be found in the nature.

Behaviour
Because of their limited freedom of speed and move, they hide in the areas they can be found. When they are under the ownership of a trainer, they are usually kept outside of the battles until they evolve. This species evolves when their process of maturing is completed. When they feel alarmed, they may be able to poison the foe in case of contact, but this incident occurs almost never.
