>>3690844>>3701608It's because his design is textbook shotabait:
>looks younger than all the other Pokemon MCs>elementary school uniform-like clothes, backpack included>same pageboy haircut every shota has in porn doujins>baby face that makes him look innocent or naive>the shorts and knee-high socks make his legs stand out more than in every other generation>the starters looking like plushies make him look even younger and more innocent>the hat and tie makes him look like a "nerd" or "mama's boy"He's simply the most adorable Pokemon MC created so far, and it's this raw inocent cuteness what pissed off so many lolicons who were used to the more "provocative" designs of previous generations (Lana wearing a swimsuit 24/7, Mallow and Marnie wearing a small top and tight shorts, Lillie and Acerola wearing dresses, female MC wearing tighter shorts or skirts etc.). They no longer can fap to the "innocent school girl" archetype that practically is a cornerstone of the loli fandom, something shotacons still can for the most part as shown by the reactions produced by the new boy.
