I need to verify if Xiaolin Showdown is available on streaming services in Latin America. Platforms like Netflix, Hulu, or Amazon Prime might have it. Also, checking if there are any official re-releases or specials in 2021. If not, the article should clarify that and explain possible origins of the 2021 date. Maybe it's a fan event or a compilation that was uploaded in 2021, but not an official episode.
