Luigi

Luigi is a character from the Super Mario fandom.

Character
Luigi (ルイージ Ruiiji) is Mario's younger, twin brother who occasionally helps him save Princess Peach from Bowser. Although more timid, Luigi has starred in his own adventures in games such as Luigi's Mansion. In-universe, he is constantly forgotten by others and is usually the butt of jokes. Despite this, he is still regarded as a kind hero.

Canon
Princess Daisy

Luigi and Princess Daisy are close friends who are consistently teased as sharing romantic feelings with each other. Examples of this include statues of them dancing together, their team names in the Mario Party series, character descriptions, and dialogue between the duo. Despite their relationship being akin to Mario and Peach, Luigi has never canonically saved Daisy in any game.

Fanon
Although not as famous as his brother, Luigi is highly regarded in the Super Mario fandom as a fan favorite character. In some ways, he is liked moreso due to his personality and role as a sidekick. Some also find his cowardly nature to be relatable. On the other end, others may find said nature to merely be an annoyance and claim the character as overrated or cheap. This is a rare opinion, though.

In terms of romantic ships, most will ship Luigi with Princess Daisy due to canon evidence and opposites attracting. The same can be said for Luigi and Prince Peasley as a pair. However, recently, there has been an increase in content of the green plumber being romantically involved with Bowser. Multiple polyships have formed due to them being popular ships in the fandom.

Super Smash Bros. has also promoted some crossover shipping. Characters shipped with Luigi include Solid Snake, Ryu, and Simon Belmont. Typically, the reasoning for these ships is their interactions. However, some find appeal in Luigi being in a relationship where he's being taught how to get stronger.

Excluding romantic pairings, the Mario Brothers themselves are a fairly popular familyship. Some may portray the relationship in a toxic light, with Luigi being jealous of Mario, but most disagree with the notion.

Currently, on AO3, there are around 500 fics featuring Luigi. For the Mario fandom, Luigi has 2,100 fan fics at Fanfiction.net. When including Mr L, it is raised to 2,200 at least. The number is dramatically lower for Smash Bros, at around 200.

Trivia

 * Luigi's first appearance in any form of media was in Mario Bros in 1983. It is also his first playable role in any game
 * In the Great Mission to Rescue Princess Peach, Luigi has both Mario's mustache and a yellow and blue outfit. His personality is also more akin to Wario here, due to his greed getting the best of him in certain cases
 * It is worth noting both Luigi's Mansion: Dark Moon and Super Smash Bros also give Luigi this color scheme for certain alts
 * In promotional art for the movie, Luigi will sometimes have a pink and blue palette instead
 * According to the movie's height chart, Luigi is 23, with Mario being 25. This contradicts both Yoshi's Island and Satoru Iwata's statement on the brothers being twins. However, both came after the movie's release. The movie itself also takes place in an alternative universe, thus causing it to be non-canonical
 * In 2013, to celebrate Luigi's 30th anniversary, Nintendo announced the year as the Year of Luigi. During this period of time, multiple games had Luigi as the central focus. Merchandise such as CDs and 3DS cases were also released to promote the event. However, sales in this period were lower due to the Wii U being considered a financial failure
 * In Mario + Rabbids Kingdom Battle, Luigi has been shown to canonically dab. Paper Mario: Color Splash also makes reference to Luigi's Death Stare, a meme formed from Mario Kart 8
 * Luigi's name in Japanese romaji is 'Ruiji.' With this in mind, Miyamoto has stated that the name was chosen due to it sounding like the Japanese word for "similar." This fits with Luigi's role as the player 2 character
 * During Shy Guy's ending in Mario Power Tennis, Shy Guy's mask falls off, causing a nearby Luigi to jump away in fear. As of now, Luigi is the only character to have seen Shy Guy's face
 * It is worth noting a similar enemy, Ghost Guy, can have its mask removed in Luigi's Mansion. Behind it are two, yellow eyes. However, its debatable if Ghost Guys and Shy Guys share the same face or not
 * The reason Luigi was green in his first appearance was memory limitations . Specifically, colors were limited, so the developers decided to borrow the Shellcreepers' colors for Luigi
 * According to several sprites and artwork for Mario & Luigi, Luigi wears red and white, striped socks. Starlow also tells him to "put his mustache back on," meaning it is likely fake and another accessory as well
 * In Fortune Street, Luigi states his hobbies are the following: golf, tennis, basketball, and beating the player at Fortune Street
 * His final smash in Brawl, Negative Zone, has no specific origins. However, the trophy states that its powers come from "the dark side he embraced in his brother's shadow." This is evidenced by Luigi appearing red inside the affected region and the smash's name
 * Some fans have speculated that it takes inspiration from Super Paper Mario, with Luigi's prophecy role deciding the fate of all worlds. However, Super Dimentio is the closest to having this be portrayed in-game, due to Luigi never willingly using either the Pure Hearts or Chaos Heart
