Waluigi is a tall, lanky, purple-clad villain from the Mario universe, designed as Luigi's rival in the same way Wario mirrors Mario. He's recognizable by his thin frame, pointed pink nose, crooked mustache, and the inverted "L" symbol on his purple cap1. His personality revolves around self-pity, jealousy, and a desperate need for attention, traits that voice actor Charles Martinet described as the "cornerstone of his character"3.

As a meme, Waluigi works on multiple levels. His exaggerated facial expressions and physical features make him perfect for image edits and reaction images5. His catchphrase "WAH!" and the fan-created "Too bad. Waluigi time" have taken on lives of their own. Most importantly, his status as a character who never gets his own game, never appears in mainline Mario titles, and was repeatedly snubbed from Super Smash Bros. makes him deeply relatable to anyone who's ever felt overlooked19.

Waluigi crossed over from gaming niche to mainstream internet culture primarily through the 2018 Smash Bros. controversy. Major outlets including Polygon6, Mashable7, and the Daily Dot2 covered the backlash as a genuine cultural event. Netflix's fake documentary tweet about Waluigi's "tragedy" showed that even major brands recognized his meme status6.

The character's appeal reached academia adjacent circles when Sam Daly's "Ode to Waluigi" won a Canadian national children's writing contest in 2012, with judges praising the choice of celebrating "an oft-ignored secondary character"2. Multiple gaming publications ran lengthy analysis pieces treating Waluigi as a legitimate subject for character study89.

Waluigi's voice actor Charles Martinet became a de facto advocate for the character, repeatedly expressing his desire for a Waluigi-centric game where cheating is the core mechanic11. The gap between Martinet's enthusiasm and Nintendo's refusal to give Waluigi a starring role only deepened the character's underdog mythology.

On TV Tropes, Waluigi earned both an Ensemble Darkhorse listing and a self-demonstrating article written entirely in his voice16, a distinction usually reserved for far more prominent characters. The site's "Hostile Show Takeover" trope page even references him directly4.

Before the internet adopted him, Waluigi had already built a strange reputation within the gaming community. Charles Martinet, who voiced the character from 2000 until stepping back in 2023, described Waluigi's personality as rooted in self-pity: "Everything goes good for everybody but me! 'Waa-haaah!' You know, a big self-pity thing"3. This depth, as simple as it was, made Waluigi one of the few Mario characters with something resembling emotional complexity.

The shift from "annoying side character" to "ironic internet hero" happened gradually across the late 2000s and early 2010s. Writers at gaming outlets began producing defense articles. Gamervision's Coop wrote "Ten Reasons Waluigi is Awesome" in 2009, arguing that "the internet needed a lesson exactly how awesome Waluigi is" and praising his height, unique abilities in sports games, and the fact that "Nintendo has no freaking clue what to do with the character"3. Unwinnable published "Waa! In Defense of Waluigi" in 2012, arguing his weirdness and unpredictability gave him a natural comedic edge and an "implicit troll factor" that made him fun to play as8. Gameranx's deep dive "Waluigi: Unwrapping the Enigma" went further, analyzing his self-pity through the lens of Rodney Dangerfield's "no respect" routine and even connecting the upside-down "L" on his hat to the Greek letter Gamma and probability theory9.

Fan-created games filled the void that Nintendo left. On Mario Fan Games Galaxy, a fan game called Psycho Waluigi gave the character telekinetic powers and over 30 kingdoms to conquer. Community members hailed it as possibly "the most official-feeling fangame ever made," with one reviewer claiming "if Nintendo made this game, they would make millions"20.

The Super Smash Bros. saga is the backbone of Waluigi's meme identity. In Brawl (2008), he appeared only as an Assist Trophy that stomps opponents into the ground before swatting them with a tennis racket17. Masahiro Sakurai, the series director, posted on Miiverse when confirming Waluigi's Assist Trophy status in Smash for Wii U: "Just because you try hard doesn't mean you'll make it into the battle"18. The community took this as both a taunt and a tragic commentary on Waluigi's whole existence.

Then came June 2018, and the announcement of Super Smash Bros. Ultimate with the tagline "Everyone Is Here!" The game launched with 74 fighters, eventually expanding to 89 with DLC. Ridley, Daisy, and the Inklings all made the cut as new fighters6. Waluigi did not. He was once again an Assist Trophy, and the Nintendo Direct footage even showed his trophy getting KO'd on screen7. The internet erupted. Polygon ran the headline "Everyone's in Super Smash Bros. Ultimate... except Waluigi," calling him a "meme icon, tennis hero and fan-favorite"6. Mashable demanded to know "what the hell is going on"7. Netflix jumped in with a fake documentary announcement exploring "the depths of Waluigi's tragedy"6.

The exclusion triggered a creative explosion. Fans photoshopped Waluigi onto every character on the Smash select screen under the banner "Everyone Is WAH!"19. Mock movie posters appeared, including "Avengers: Infinity Wah" with every Marvel hero replaced by Waluigi5. The "persecution complex" memes painted Sakurai as having a personal vendetta against the character, sometimes editing his face onto Thanos19. What made the whole thing work was the self-awareness. Fans knew the outrage was performative, but the bit was too good to drop.

Through all of this, Waluigi earned recognition on TV Tropes as a textbook example of an "Ensemble Darkhorse," a character who becomes wildly popular despite minimal screen time4. The site even has a self-demonstrating page written entirely in Waluigi's voice16. Martinet himself said he wanted a Waluigi solo game: "I'd love to see a Waluigi game where you have to cheat to win, ya know. That would be funny"11. Nintendo never obliged.
