Cool Trainer is a type of Pokémon Trainer that debuted in the Generation I games. They are depicted as teens or young adults with whips. They lose their whips in Generation II. The title Ace Trainer is also used in Generation IV and onward.
I remember playing the first generation of Pokemon and noticing how cool Cool Trainers looked. When I was deciding on another simple Pokemon cosplay to create, I remembered back to these early days. To pair with the Cool Trainer outfit, I created a life size Bellsprout puppet that worked like a marionette.
