What is a living dex?
A living dex is having every single Pokémon in your boxes. I'm taking this a step further and saying this also includes every form, including gender differences. So for example, it isn't enough to get just female Venusaur or Red Flabébé; I need male Venusaur and White Flabébé.
A shiny living dex is the same thing, but... shiny. Obviously, this doesn't include Pokémon that have never been released as shiny.
At the moment this page is a bit of a placeholder. The eventual goal is for it to list my progress and whatnot but that seems like a lot of JavaScript that I do not know yet lol
