|First Game||Mario Tennis (2000)|
Mario, Luigi (rival and sometimes friend)
|Voiced by||Charles Martinet (2000-present)|
Waluigi is a reoccurring character found in the Mario series who was made to rival Luigi. Waluigi mainly only appeared in spin-off games such as Mario Tennis and Mario Party 3. Waluigi is known to be Wario's partner ever since Waluigi made his first appearance in Mario Tennis for the Nintendo 64 and was voiced by Charles Martinet ever since. Waluigi also appeared along with Wario and Luigi in Super Mario Advance games as a palette swap of Mario. He has also appeared in every Mario Party game since Mario Party 3 came out in 2001.
Waluigi's hat has the letter Gamma on it, showing his rivalry with Luigi, similar to Wario who has a W on his cap, shown to be an upside down M. Waluigi wears black overalls and purple clothes. He likes causing trouble and he doesn't give credit to Mario for completing his adventures.
The details of Waluigi's past are unclear since he has no confirmed background, although he was evidently been antagonizing the Mario Bros., especially Luigi, for quite some time before his debut as seen in the opening of Mario Tennis, where he and Luigi confront each other.
Waluigi's first appearance was in the Mario Tennis for the Game Boy Color and Nintendo 64, as Wario's doubles partner. Later, along with Princess Daisy, he joined the Mario Party series' roster in Mario Party 3 where he played an antagonistic role, in which he owned an island full of traps; he has been a playable character in many entries in the series since, as well as various Mario sports and kart. He and Wario were also the main characters of the intro movies to Mario Golf: Toadstool Tour and Mario Power Tennis. He acts as an antagonist in Dance Dance Revolution: Mario Mix, in which he wreaks havoc in the Mushroom Kingdom by stealing special objects called the Music Keys in order to hypnotize the world with his dancing, thus enabling him to conquer it.
Mario Party series
Mario Party 3
Mario Kart series
Mario Kart: Double Dash!!
Waluigi makes his first playable appearance in the Mario Kart series in Mario Kart: Double Dash!!. Waluigi is a middleweight character and his partner is Wario who share a Bob-omb as their Special Item, along with Waluigi Stadium being his course, and Waluigi Racer noticeably being his kart.
Mario Kart DS
Mario Kart Wii
Waluigi returns once again in Mario Kart Wii as default character. Unlike in Mario Kart: Double Dash!! and Mario Kart DS he is classified as a heavyweight character with his acceleration bonus being tied with Toad. Also Waluigi Stadium from Mario Kart: Double Dash!! returns as a retro course.
Mario Kart 7
Although Waluigi does not physically appear in Mario Kart 7 (though he was supposed to appear), Waluigi Pinball from Mario Kart DS does return as a retro course.
Mario Kart 8
Waluigi returns in Mario Kart 8, once again as a default heavyweight character like in Mario Kart Wii. However is classified as one of the lighter heavyweights alongside Donkey Kong, Rosalina and Roy Koopa.
Super Smash Bros. series
Super Smash Bros. Brawl
While Waluigi is not in the roster of playable characters, he appears as an Assist Trophy, along with his tennis racket, in a nod to his first appearance.
Super Smash Bros. 3DS/Wii U
Waluigi returns as an Assist Trophy in this game. Oddly he is representing the Wario series instead of the Mario series, but this could be a error since Waluigi has never appeared in them. Waluigi acts the same in Brawl except he moves much faster and his attacks are a tad stronger.
Waluigi and Wario appear to have a complicated relationship, sometimes working together (as seen in Mario Super Sluggers) or competing. Waluigi's partner in Mario Kart: Double Dash!! is Wario, as well. However, Waluigi has never been confirmed to be Wario's brother.
Waluigi has a crush on Daisy. However, the two share bad chemistry and Daisy never returned her feelings to him.
- Waluigi was meant to be a playable character in Mario Kart 7, but he was scrapped to time constraints. However, the course Waluigi Pinball does appear as a Retro Course.
- According to the official guide to Mario Party 5, Wario and Waluigi are not brothers.
- Mario Tennis: Power Tour is the only game where Waluigi appears without Wario.
- Waluigi appears in every Mario Party game since Mario Party 3 as a playable character except Advance.
- Waluigi was rumored to be in Super Mario 64 DS , but no one has a video of playing as him. Proof: 
- In Paper Mario: The Thousand Year Door, Mario is able to change his clothes into Waluigi's by wearing both the L Emblem and the W Emblem badges.
- In Super Smash Bros. Brawl and Super Smash Bros. for Nintendo 3DS/Wii U, one of Luigi's costumes is based on Waluigi's outfit. Mario also has a Waluigi costume.
- After Mario Party 3, Waluigi has been an ally to Mario in every Mario Party game except Advance.
- As of now currently, Waluigi is the only character of the main/major cast to not appear in a main series game.
