Kakuna

Instead, Weedle evolves into Kakuna, accurately resembling a Hymenopteran pupa and a whole lot cooler looking than its counterpart, Metapod. I even thought Kakuna was so cool in my youth that I kept one on my team and didn't evolve it. I kept on training a Kakuna with poison sting and harden like it was a badass addition to my team all on its own. I had no concept of the metagame, of strategizing or that some pokemon were inherently less good than others no matter how high their level. It was a simpler and happier time to be a pokemon kid.
