>>22410101It's not a meme. This discussion is as old as 2004.
"Leaf" appears in a part of the code of the games that contains unreliable data, since the player's rival, who is canonically called Green in Japanese and Korean or Blue in English and other Western languages in every generation, is called "Terry" (dunno the Japanese equivalent). This was picked up by Bulbapedo and popularized due to its massive traffic, which is on par with Serebii's.
Furthermore, "Leaf" does not fit with the Kanto theme motif logic. Her name HAS to be Blue in Japanese and Korean or Green in English and other Western languages.
