Franchise: Super Smash Bros.

In German versions of the Super Smash Bros. games, Popo had his name changed to "Pepe" because the word "popo" means "butt" in German.

In the November 2014 issue of GameInformer, it was revealed that Masahiro Sakurai takes photos of a pose-able action figure to create the moves for new characters whenever one is being made. The image shown is the action figure poses used to make the Mii Fighters' moveset.

When performing Bayonetta's forward throw Tetsuzanko, she'll occasionally say "Juu'nen Hayain Dayo!" which in English translates to "You're Ten Years Too Early!".

This is a reference to one of the the win quotes of Akira Yuki from the Virtua Fighter series in which the Tetsuzanko is also one of Akira's signature moves. This move was also possible in Bayonetta.

Bowser Jr. takes less damage from any attacks that hit his clown car and not his body.

Masahiro Sakurai wanted Geno to appear as a playable fighter in both Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS and Wii U, and thought the character felt suited for the series since he has a gun for a hand. However, in the end he wasn't included, but instead appearing as a Mii Costume in both the latter game and Super Smash Bros. Ultimate.

Mentioning Project M, the name of an unofficial modified version of Super Smash Bros. Brawl to reintroduce elements from Super Smash Bros. Melee, by name on any of Nintendo's Miiverse channels will trigger an automatic ban for discussing "criminal activity".

Series creator, Masahiro Sakurai, has stated that each game in the series except the original were developed with the mindset that there were to be no more sequels after them.

Some of Meta Knight's palette swaps in Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate resemble other characters from the Kirby series.

Domestic and international popularity polls are used when deciding who to add into a Super Smash Brothers game. After that, certain questions such as whether a character can present something interesting and whether they're a good representative of their series are asked.

Charizard's purple alternate color in Super Smash Bros. for Nintendo 3DS and Wii U and Super Smash Bros. Ultimate is possibly a reference to his shiny sprite in Pokemon Gold and Silver. Including purple skin, a grey-white belly and dull green wings.

When Mega Man gets KO'd, his KO explosion has blue spheres coming out from where he was KO'd. Mega Man is the only character in the series to have a unique KO explosion, and is a reference to his death animation from the Mega Man series of games.
