- Actor Allusion: While Hiroki Yasumoto has voiced Machamp before, his recent stint as the multi armed god like warrior that is Asura makes his voice for Machamp all the more badass.
- Cowboy BeBop at His Computer: A number of people refer to Pikachu Libre as a he. This is despite the fact that a quick google search will tell that, thanks to the heart-shaped notch in the tail, Pikachu Libre's actually a female.
- Dueling Works: Marvel vs. Capcom: Infinite was released in the same week as the DX re-release, developed by Bandai Namco competitor Capcom and released on mutually exclusive platforms (The PS4, Xbox One, and PC to DX's Switch release).
- Fandom Nod:
- One of the stages has a person in the background riding a bike while being followed by a Volcarona, a reference to how players keep a Volcarona in their party while hatching eggs.note
- Prior to the first arcade release, there was a Twitter campaign in Japan (from the game's official Twitter account) that asked fans to vote for which Pokémon that they would like to see added to the game as a playable character. Magnemite won the poll, but runner-up Gengar was selected instead for unspecified reasons. When Gengar's trailer was released, some Magnemite are briefly shown holding the In-Universe camera to acknowledge the poll's true victor.
- In 2014, Se Jun Park gained notoriety for winning the Pokémon World Championships Masters Division with a Pachirisu, spawning thousands of memes and pieces of fanart over the web — especially in regards to its frequent usage of the move Follow Me. Guess which move Pachirisu uses as an Assist Pokémon in this game?
- Shadow Mewtwo is one as well. With the original Japanese text confirming that it is a "Dark Pokemon" with the same terms as Pokémon Colosseum and Pokémon XD: Gale of Darkness did, it's the first time the Ensemble Dark Horse Orre games' signature Shadow Pokémon have shown up or even been referenced in over a decade. Especially with the fan rumors of a rerelease after Omega Ruby and Alpha Sapphire were announced, Pokken's tip of the hat to the game was well received by fans of those games.
- Fan Nickname:
- God Never Said That: As fans discuss possible Pokémon that will be made playable in Pokkén Tournament, a common argument against any suggestion is if said Pokémon is already featured in some aspect in the background of a stage, that it means it's extremely unlikely to be included in any other way (possibly due to such an implementation being perceived as redundant and/or a waste of resources). This "rule" was never said or even implied by the creators, and in fact, with the inclusion of Chandelure into the roster (who is also featured in the background of the Haunted Mansion stage), this fan myth has officially been busted. Braixen's inclusion, meanwhile, busts the belief that if a Pokémon is an Assist Pokémon, its evolutions can't be playable or that (outside of series mascot Pikachu) that it has to be fully evolved (a belief that may have arisen since being "fully-evolved" indicates that a Pokémon has access to its most powerful natural form, thus being suitable for a fighting game that emphasizes strength, and that most of the tougher challenges in the core series Pokémon games feature solely fully-evolved Pokémon).
- Doubly so with Croagunk, who was, and still is, a Support Pokémon.
- No Export for You: The arcade version is Japan-exclusive, though a few cabinets were sent to select Dave & Busters. Averted for the home-console release despite many initial fears (except for South Korea, as of January 2016).
- Additionally, the 4 new playable Pokémon that have been added to the roster (Darkrai, Scizor, Croagunk, and Empoleon) are currently only available in the arcade version. There don't seem to be any plans to port these characters over to the Wii U version at this time, despite data referring to them being added in an update for said version. Ultimately, they were held back for the Switch version.
- The Other Darrin: Charizard is voiced by Kensuke Sato rather than Shin-ichiro Miki. Miki voices Ash's Charizard in the anime and Red's Charizard in Pokémon Origins and in Smash, while Sato voices Alain's Charizard in the anime. This indicates that this Charizard is more based on Alain's rather than Red's.
