Pokémon Scarlet and Violet's internal codename might be "titan" according to official website source code
A titan discovery!
On Pokémon Day, soon after Gen 9’s reveal, the word “titan” was plastered throughout the source code of the official Japanese Pokémon website. Now, it seems as though all mentions have been replaced with “SV”, an obvious acronym for Scarlet and Violet.
We’ll have to wait and see if there is any meaning behind this mysterious potential codename.
