He is Luigi's evil doppelganger and Wario's adopted brother. He and his brother are homeless crooked criminals running around the Mushroom Kingdom, trying to gain money by any means, such as: scamming people, robbing banks, joining alongside other villains (namely SMG3), or simply a Taco stand. Waluigi can also be shaped into a rocket launcher, which others would call the Waluigi Launcher. He has a love-hate relationship with Wario, but the two always get along.
While Waluigi is cool and attractive, he sometimes appears to other people as annoying and stupid (exemplified by how he doesn't even know how to write an 'L'). For being rejected in Smash for far too long in SMG4: Waluigi's Time, he brings out his rejection and anger on everyone else until he gets into Smash. He became the main antagonist of the Waluigi Arc, where in his rejection-powered form called the WaluRambo, he gained amazing powers such as shapeshifting, mind-control and the ability to T-Pose anyone (with the exception of Master Hand) with his Staff of Rejection.
This power is the cause of SMG4: Mario And The T-Pose Virus when Waluigi conjured a T-Pose Shroom to turn anyone into a T-Pose Zombie. During the Waluigi Arc, he tried to get all the other characters to hate him to reach his final form, to the point of torturing Mario and Luigi as seen in "Mario SAW".
During this time, Waluigi became a megalomaniac and went insane with his rejection powers, and his disappearance caused Wario to be lonely, which in term caused him to disappear as well. Thankfully, in SMG4: War Of The Fat Italians 2018, Waluigi reunited with his brother, thanks to SMG3, who is a therapist, and redeemed himself and reconciles with his brother. Despite this, Waluigi is still insecure over being rejected.
Waluigi's origins in the Nintendo canon is mostly unknown, due to his creators not sharing much information about him. His voice actor, Charles Martinet claimed he and Wario were "two evil guys who found each other."
The SMG4 version Waluigi was born and raised in the WAA kingdom with his older brother Wario, as revealed in The Wacky Wario Bros.: Waluigi Origins. When the two were children, they fought over Garlic Ice Cream near an ocean cliff, eventually causing the frozen treat to fly out of their hands and into the water. Wario attempted to catch the Ice Cream by jumping off the cliff, but Waluigi tried to save him by catching and pulling him back up. The attempt failed due to Waluigi's weak child arms, and Wario ended up falling on Toadsworth's boat to the Mushroom Kingdom. After being separated from his only known family member, Waluigi had begun to act very mischievously and greedy, causing him to grow up into the villain we know today.
Years pass. Waluigi had become the most famous criminal in the WAA Kingdom, causing violence and destruction, threatening the peace of the Waa citizens. Waluigi is taken into court, but rather than admitting his crimes and apologizing, he flips the entire courtroom off, causing him to be sent into exile.
Waluigi soon came upon the Mushroom Kingdom in his exile boat. After making it to the coast, he encountered Wario, who had just recently stolen a golden statue head from Bowser. Waluigi tried taking the gold from him, and the two fought over it until Bowser arrived, along with the MK Border Security to arrest Waluigi for illegal immigration.
While not to the degree his brother Wario is, Waluigi is greedy and will overcome many obstacles for a small personal gain. He is smarter than his brother and tends to be more focused on the task at hand when his cowardice doesn't get the best of him.
Also notable is that in the Wacky Wario Bros. episode: Money Mayhem, Waluigi spent about $800 bucks on weed, assuming that Waluigi smokes a lot and likes getting high. Despite his selfish demeanor, though, Waluigi has shown sympathy to others, including Fishy Boopkins in SMG4: Stupid Mario Tennis Aces.
Sometimes, Waluigi sells tacos at his taco stand, however, he doesn't have a lot of customers besides Mario and SMG4 (as seen in War Of The Fat Italians 2017). As of SMG4: Waluigi's Time and up until SMG4: War Of The Fat Italians 2018, Waluigi became a major villain in the SMG4 series, replacing SMG3. Compared to previous villains, Waluigi was not comedic.
In Waluigi's Time, the video mostly consisted of Waluigi trying to come up with his Special Move to convince Master Hand that he was worthy of being added to Super Smash Bros. Ultimate's roster as a playable character. As hard as he tried, though, Waluigi didn't have any luck in this endeavor and was forced to accept the reality that he would never be in Super Smash Bros.
Ironically, this led to Waluigi getting his Special Move, as the sheer pain of the thought of being forever rejected and hated was so strong that Waluigi gained a superpower: the ability to "share his pain" with his victims, causing them to be overwhelmed with sadness and thus unable to fight back.
Waluigi showed off this new power to Master Hand, who was impressed enough to finally accept Waluigi into Super Smash Bros. Unfortunately, finally being accepted into something caused Waluigi to lose his powers, causing Master Hand to instantly demote him to being an Assist Trophy again. This ended up being a huge mistake on Master Hand's part, though, as Waluigi regained his powers after that, to turn into WaluRambo, an omnipotent demigod capable of various dark magic abilities. In exchange of becoming WaluRambo, he then used his powers to cause chaos around the Mushroom Kingdom for the next couple months (including enslaving Master Hand) before Wario with the help of SMG3 stopped him.
Powers and abilities
Waluigi is assumed to have the same abilities as everyone else in the Mushroom Kingdom, such as superhuman athleticism, strength (not as much as Wario, and not nearly as much as Mario) and durability.
However, Waluigi does have some unique traits. He is considered a master at tennis, having his only known loss be against Fishy Boopkins. Waluigi has also been shown to be able to swim through the air.
