Beautifly in depth
Ageha plus hunt
アゲハント is formed from 揚羽蝶 (agehachō), swallowtail butterfly, joined to the English word hunt. Both halves of the character in four syllables. The Western name kept only the first half — beautiful plus butterfly — which is why the entry about driving its mouth into a rival to drain their fluids catches anyone coming from English or Spanish off guard; Spanish inherited the name as-is.
The specific reference is the black swallowtail, both in the shape of the wings and in the pattern. What strays furthest from the real model is the proboscis: in a butterfly it is a soft tube that coils up out of the way, while here the entries keep insisting on describing it as a spiral needle.
The draw that decides the branch
Wurmple is the most extreme case of hidden evolution in the game. There is no stone, held item, time of day or friendship level involved: when it reaches 7, it cocoons itself into Silcoon or Cascoon according to a value assigned to the individual when it appears, invisible on every screen in the game. Three levels later, Beautifly or Dustox emerges. Anyone who wants both has no choice but to catch caterpillars until the other side comes up.
The split between the two branches is designed as a mirror image. Beautifly gets the special Attack and the bright palette; Dustox leans towards defence, the Poison type and the look of a nocturnal moth. It is the same idea as Butterfree and Beedrill in Kanto, with the difference that there the two lines start from different caterpillars, while here they are decided by a coin toss.
Ten points that changed nothing
Up to Generation V it totalled 385, with 90 Special Attack. Generation VI raised that stat to 100 and left it at today’s 395. It was one of many tweaks to minor Pokémon in that overhaul, and here it changed nothing: ten points do not give it a single new calculation against anything with real defences, and the problem was never the Attack number but the 50 and 50 behind it.
The comparison that hurts most is with Butterfree, the other early-evolving Bug and Flying butterfly. Butterfree has powders that put foes to sleep; Beautifly is left with Stun Spore, learned at level 11, and there is nothing in its level-up list that makes up for the difference. Between Silver Wind at 18 and Bug Buzz at 43, twenty-five levels pass in which its best STAB attack stays at 60 power.
Contests before battles
Where it did work was outside battle. In the anime, May’s Beautifly evolved in the middle of the Hoenn journey and became her Contest Pokémon for the whole arc; May herself decided to become a Coordinator after watching a rival’s Beautifly win a Contest. It is a Pokémon built to be looked at, and the series made better use of that than any game.
