Butterfree was caught as a Caterpie and evolved to a Metapod in the episode Ash Catches a Pokémon. Metapod then evolved when defending Ash from a flock of Beedrill. He caught it only by throwing out a Poké Ball. He once traded his Butterfree for a Raticate, but he missed his Butterfree so much, so he traded back. It seems to be a male Butterfree and was released to start a family with its mate, a pink Butterfree. Before winning the heart of its mate, Butterfree saved a bunch of wild Butterfree from Team Rocket (this caused the pink Butterfree to start having feelings for him.) Butterfree's current location is unknown. It will return in BW132.
