Although they belong to neither of the two types, steel and dark, which have so often confounded and developed our understanding of the elements, there is no pokemon more associated with alchemists than the Beautifly. Unlike most pokemon, whose attacks are developed entirely internally, a Beautifly's thorax is so small and fragile that attacks from Stun Spore to Bug Buzz are produced in plain view on their multicolored yet semi-transparent wings.
Many an alchemist has spent their life studying Beautifly in the hope of infinite wealth by discovering the secret of how to turn Silver Wind into silver coins or simply pure, solid silver. Although they failed to even teach this pokemon Pay Day, they discovered a great deal about how pokemon attacks worked. Although these moves have never been taught to other pokemon, they first learned how to mix Beautifly's status powders such as Stun Spore and Sleep Powder for themselves, and were employed by bodyguards and assassins for their mastery of these chemicals. The first Move Tutors in Hoenn are descended from Beautifly alchemists, although the two groups diverged in the centuries when alchemy became impossible after Silcoon were hunted to virtual extinction for their silk. When Beautifly spread their wings again across Hoenn's skies, a more scientific age developed the first technical machines in Hoenn (and arguably in all the pokemon world) from attacks such as Attract and Giga Drain. However, because Hoenn's numbering system is not based on discovery date, but on alphabetical order in Hoenn's ancient script, these techniques are actually numbered fairly high in the TM registry.
Ironically, this science sparked by Beautifly's wings has been of little use to them in combat; their best attacks, Quiver Dance and Bug Buzz, are learned without any help from the masters of pokemon alchemy and chemistry.
