Hello. In this challenge, you go through the games as you normally would, starting from the original Kanto games all the way through Black and White, but with a twist: you can not evolve any Pokemon. All Pokemon must stay in the form you caught them in. Therefore, if you catch a Pidgeotto, it can stay a Pidgeotto and still be used, but not evolve into Pidgeot. But if you catch it as a Pidgey, it must stay as a Pidgey.
