>>58240403The only people buttmad about it were buttmad about literally every anime reference these games have had. They also seethed about Steven referencing Alan from the Mega Evolution Specials, they seethed over the blurry photo of Ash and Pikachu in Totem Mimikyu's room and they seethed when he got into Master SEX, even going so far as to DARE being in a trailer alongside Red-sama.
Seething from autists also doesn't magically mean it's not popular considering just how many people loved the form in the anime because hype moments and aura is enough to excite anyone these days to say nothing of the people who go on Smogon and pick the most broken Mon to gloryhog and sure enough, A-Greninja was pretty goddamn strong.
