I need to check if there's any official info on a Kanto Syncro in Pokémon Legends: Arceus. From my knowledge, in that game, you choose a Sync pair partner from the Arceus region, not Kanto. So maybe a mod or fan content adds Kanto Pokémon as Sync pairs. The "Crack" part might refer to an exploit or cheat allowing players to change their Sync pair to a Kanto Pokémon, which wasn't allowed originally.
