Here's the thread where we can add rumours and fake scans about Pokémon Scarlet and Violet (they are fake until they are proven from the official CoroCoro scans or the official website).
Already confirmed fake:
A prototype of Pokemon Diamond/Pearl leaked online and the beta names for the Sinnoh Starters were discovered :yesyes2: :sisi2:
Azelf's English name is similar to it's Japanese (Agnome) and Cyrus lacks a name in some texts, known as Boss.
Lucas is also often known as 'Lukas'.
