What do you think about this idea I have about butterfly and moth Pokemon? First I’d mash them into one evolution, Caterpie into Butterfree during the day, and Venomoth during the night. I’d change them the Bug/Psychic and Bug/Dark respectively, then give them different forms based on what region they’re found in. Hoenn Butterfree is Bug/Fire with a sun motif, and Venomoth is Bug/Water with an ocean motif, in Kalos Bug/Fairy and Bug/Ghost… they’d have signature abilities that change also.

What is the logic behind the form changes?  I mean, sure, there’s nothing wrong with the idea, and it gives Butterfree and Venomoth something neat to do (poor Venonat, though… is it actually necessary to merge the evolutionary lines?  What aim does that serve?), but it needs some flavour stuff behind it and not just game mechanics.  We’ve seen Pokémon that have different appearances in different parts of the world before – Shellos/Gastrodon and Vivillon – but they don’t have this variation in their powers.  What is it about Butterfree and Venomoth that makes them so adaptable?

I can’t help but wonder whether the effort is misplaced…  Beautifly, Dustox, Mothim and Vivillon need upgraded powers way more than Butterfree (who has Compoundeyes Sleep Powder) and Venomoth (who has Quiver Dance, Baton Pass, and Tinted Lens).
