Ascended Fanon: A collective, self-created instance, but this tends to be how the lore unfolds. Someone comes up with a good piece of art or an explanation for an indecipherable nickname, and if the fanbase likes it, the story rolls with it.
Follow the Leader: To the point when nearly two years later, on January 14, 2016, Twitch made a category called "Twitch Plays", where the requirement is the Twitch chat must have control on either a game or something else (but not people acting out feedback, as in the Old Spice Nature Man). Some examples, made before the category introduction, include:
Twitch Plays Pokémon Plays Tetris. The same players who are playing Twitch Plays Pokémon, and all their control inputs, are ALSO playing Tetris at the same time.
The app version of Twitch will occasionally recommend the user to consult Helix if the app fails to load properly.
Twitch Plays Pokemon as a whole has been indirectly acknowledged by The Pokemon Company International, who, as a part of the Milestone Celebration of the series as a whole, hosted a 24-hour marathon of Pokemon movies on Twitch named "Twitch Watches Pokemon".
There's a line from the French version of Omega Ruby and Alpha Sapphire, where Brawly says he got inspired to study Pokémon after observing a Helix Fossil for days.
The official Pokémon twitter making a joke regarding how people worship Helix.
A video was posted to various official Pokémon accounts asking people to rate a team; said team is a recreation of the final team from Twitch Plays Pokémon Red.
Missing Episode: The first 41 hours of the stream do not survive because no one was recording until then. The existant footage begins with the mob already in Cerulean City.
Urban Legend of Zelda: No, the Red ROM was not hacked to make all Pokémon available, though it was originally intended to be. No, grinding money with Meowth is not an option (although the presence of the TM Pay Day makes it possible with other Pokémon). Also, the step counter in the Safari Zone was not removed in any attempts, as shown below.
The designer said that he might have turned the step count off in the Safari Zone if needed, but he wanted to see if it can be solved without that change first. Luckily, Democracy Mode helped make that possible.
They also stated that there would be no Emerald playthrough if Red was not defeated by day 20 of Crystal. Since Red was defeated less than a day after the announcement, we'll never have to worry about that. Hopefully.
Two of the games that were supposed to be played during the fifth season were Team Rocket Edition, a FireRed hack, and Metronome Sapphire, in which every move would've been replaced with Metronome. Due to the former being deemed to unstable by the development team to be played on stream, and the latter proving more difficult to set up than expected, they were replaced with Flora Sky and Fused Crystal instead.
Both Inverse White and Inverse White 2 were meant to include a patch that would give more accessible alternate evolution methods to Pokémon that normally evolve via trading, but the feature turned out not to work as intended and was dropped as a result.
The same players who are playing Twitch Plays Pokémon, and all their control inputs, are ALSO playing Tetris at the same time.
