Butterfree was the first Pokémon shown in the anime to have an alternate color, pink. This has only been seen in a single female, and unlike a Shiny Butterfree, which has green eyes and pink wings, limbs, and snout, this Butterfree only differed in its pink body and wings.
Butterfree has been trained by four important anime Trainers: Ash, Ritchie, Solidad, and Drew.
Butterfree shares its category with Beautifly. They are both known as the Butterfly Pokémon.
Butterfree can be seen as a parallel to Beedrill. Both of their unevolved stages evolve at level 7 and again at level 10. They both go through metamorphosis-like evolution and have the same base stat total of 395. Also, while Beedrill is exclusive to Black and Black 2, Butterfree is exclusive to White and White 2.
