- Development Gag: Two of the event matches' names, "Super Mario 128" and "Kirby's Air Raid", respectively reference a GameCube tech demonote and the then-stuck in Development Hell Kirby Air Ride.
- Fan Nickname: The cloud that moves back and forth on the Yoshi's Story map has been christened "Randall" by the competitive community.
- God Never Said That:
- Sakurai never said that James Bond and Banjo and Kazooie were considered for Melee. The exact quotes regarding them were that it would be difficult securing the rights to put them in and that a lot of people were expecting Banjo, but he didn't say anything about considering them for inclusion.
- Likewise, Sakurai never said anything about considering Lip for the original game or Melee. He did call Panel de Pon a "masterpiece" when asked by a Japanese fan if Lip would be in the second game, but to all appearances, she was never planned to be included in either.
- Due to a Neogaf post claiming to have information about Melee's development from early 2000s Famitsu issues that appeared legitimate, it was for a long time that things such as Dedede being planned for inclusion, Leif and Wolf being originally planned to be clones of Marth and Fox respectively before Sakurai decided on Roy and Falco, and the Pokémon Trainer with the Gen 2 starters being planned but scrapped because of development issues, were considered accepted fact about Melee by the Smash community. The Neogaf post was eventually debunked though as being a complete fabrication.
- Killer App: Melee sold over 7 million units, making it the biggest system seller for the GameCube. It's also the killer app of the series because it created the tournament scene for the series, and it still has its own tournaments over nineteen years after its release.
- Marth Debuted in "Smash Bros.": The Trope Namer:
- Marth's debut game (technically a remake thereof) did not appear in American and European markets until 2008, almost seven years after his first exposure to Western audiences. Lip's Stick also has yet to be seen in its natural habitat.
- Roy takes the trope to extremes, also being from a Fire Emblem game that not only was limited to Japan, but hadn't even been released before Melee hit shelves; he really did debut in Smash Bros., in other words. Fire Emblem: The Binding Blade didn't release until late March of 2002, while Melee came out four months prior.note
- K.K. Slider appears as a trophy in this game, a year before the first localized Animal Crossing game was released; as a result, the overseas versions' trophy calls him by his Japanese name, Totakeke, and his game of origin is listed as "Future Release".
- New Work, Recycled Graphics: The Pokémon models used in the Poké Floats stage were directly ripped from the Pokémon Stadium games.
- No Dub for You:
- Most of Fox and Falco's voice clips were muted, even though they spoke in the Japanese version. This was changed in Brawl.
- In English localizations, Mewtwo only grunts and laughs, while in Japanese it has spoken victory lines.note
- Screwed by the Lawyers:
- Melee was supposed to boast a bevy of trophies from Rare games, but they didn't end up in the final version (probably because of the incoming buyout). By extension, this is likely why Diddy Kong doesn't have a trophy despite Dixie, K. Rool, and even Donkey Kong Junior and Stanley having one.
- Sukapon was supposed to have a role in the game (apparently as an item), but had to be dropped due to unspecified legal issues. It would take him until Super Smash Bros. Ultimate to be implemented as an Assist Trophy.
- Serendipity Writes the Plot:
- The reason why Melee infamously had so many of its newcomers as clones (with 6 of the 14 newcomers being clones). Originally the planned roster was going to be what it ended up minus the clones, as Sakurai couldn't add many newcomers with the very short development time he had for the game. However mid-development he felt fans would be expecting a larger roster and would be disappointed with the roster size, so he wanted to add more characters to the roster, but it would have been impossible to create even just one more unique new character with the time he had, thus he had to create clones of existing characters to beef up the roster. Ganondorf's infamous status as a Moveset Clone of Captain Falcon in the series stemmed from this decision. Despite doing very well on the official Smash 2 poll (where Ganondorf outperformed all the other Zelda characters combined), Ganondorf wasn't planned to be on the playable roster, with Zelda and Sheik instead being the newcomers from the Zelda series. However during the cloning process Sakurai needed some clone candidates, where he decided to add Ganondorf, as Ganon's immense popularity and status made him an ideal pick, while having a very similar body build to Captain Falcon made him an ideal clone candidate (as you could put his model over Falcon's skeleton and have him be able to use all his moves with minimal-to-no technical issues). As such, he was given an altered version of Falcon's moveset to include him in Melee, and due to Sakurai not wanting to change characters heavily from their debut appearance to avoid alienating fans who enjoy playing the character in Smash, Ganondorf has remained a semi-clone of Captain Falcon since.
- Luigi doesn't use the Poltergust because HAL wasn't aware of Luigi's Mansion until well into the development cycle.
- Throw It In!: According to an interview with Sakurai in Nintendo Power, the infamous wavedashing exploit was discovered before Melee had finished development. He didn't have it removed because he didn't think it would affect the game heavily.
- Urban Legend of Zelda:
- Rumors of Sonic and Tails being unlockable characters. In Brawl, the very same rumors actually came to fruition this time around — at least for Sonic. (Tails is just randomly-occurring stage decor, along with Knuckles and Silver.)
- There was an infamous rumor that Toad was unlockable by shooting every credit at the end of the game.
- What Could Have Been: Has its own page along with the rest of the series.
