Pokémon spoiler alert: creature roster leaks ahead of 'Sword and Shield' launch

Leek-wielding duck Sirfetch'd has been officially revealed as exclusive to 'Pokémon Sword.'

The Nintendo Switch's first mainline entries to the "Pokémon" franchise build on the popularity of mobile smash "Pokémon Go." For those that want to discover its set of wild and wonderful new creatures within the game, it might be time to look away from key words and phrases until after "Pokémon Sword" and "Pokémon Shield" release on November 15.

With less than two weeks to go until the very highly anticipated "Pokémon Sword" and "Pokémon Shield" release for the Nintendo Switch, a new round of leaks appears to confirm the games' Pokédex -- its roster of collectible and encounterable creatures -- as well as their various stages of growth.

The Pokémon Company has already detailed major adjustments to form and function in "Pokémon Sword and Shield," though has stopped shy of issuing a full list of creatures populating the games.

Players with early copies and social media accounts, coupled with datamined information, have helped fill in the gaps in community knowledge, leading to the creation of several work-in-progress lists through video game fan forum ResetEra, for those that are interested.

Details include the new cohort Pokémon creatures introduced to the franchise through "Pokémon Sword and Shield," the Pokémon populating the games' Galar region, and the various ways that those Pokémon can change form during play.

Revealed as part of the official "Sword and Shield" publicity campaign, Galar is The Pokémon Company's riff on Great Britain.

Previous games in the "Pokémon" franchise featured regions inspired by various Japanese prefectures, as well as the USA, France, and Hawaii.

As with other popular media franchises such as "Game of Thrones" and "Stranger Things," fans that want to block spoilers without undergoing an internet blackout might try using built-in social network content-filtering options: Twitter's user and word Mute functions, Instagram's Manual Filter, and Facebook's group and user Snooze function, or independent Facebook enhancement suite Social Fixer.
