How do i input Pokémon sprites onto a post without searching for it online? I know that is what the Pokéball symbol is on the top of the typing thing, but how do i use it?
See here: https://lakevalor.net/help/bb-codes (Scroll down a bit) For the forms, you can put xerneas-active or shaymin-sky for example, it's not only for the Alolan and megas (for mewtwo it's megax or megay btw) and of course you can combine shiny and forms.
