Wario

"Obey Wario, destroy Mario!"

"I'm-a Wario! I'm-a gonna win!"

"Here I go!"

Wario is the "evil twin" of Mario and a major antagonist in the Mario franchise, although his role has often shifted to an anti-hero. Wario first appeared in Super Mario Land 2: Six Golden Coins as the main antagonist, where he put an evil spell over Mario Land.

Wario has appeared in many games including Super Smash Bros. Brawl, the Mario Party series, The DS version of Super Mario 64 and several of his own games, particularly the WarioWare series.

Wario has also became a hero in the Wario Land series.

Wario is called "Beetle Brows" By Bowser Jr. in the Mario Baseball games.

Just like Mario, Luigi, Waluigi, Baby Mario & Baby Luigi, Wario is voiced by Charles Martinet.

Personality
In direct contrast to Mario, who is heroic and kind, Wario is incredibly greedy, lazy, ill-mannered, and manipulative. He will only agree to something if there is a reward (preferably money) involved; he is easily susceptible to bribes. He is hugely jealous of Mario's fame, and has frequently tried to steal enough wealth to make himself as beloved as Mario. While he has been rich at times (to the point of owning his own giant castle full of golden coins more than once), usually his get-rich-quick schemes seem to go wrong. According to a comic story published in Nintendo Power, the reason Wario acts the way he does is because Mario bullied him when they were both young. Wario especially hated playing cowboys, because he was almost always the rustler that the sheriff, played by Mario, had to arrest. Wario would lose to Mario either way.

Wario started out as more of an evil character. In a commercial for Super Mario Land 2: 6 Golden Coins, Wario attempts to hypnotize the viewers into serving him. He continues on with his evil streak in Wario's Woods and Mario and Wario, while also playing an anti-hero role in Wario Land: Super Mario Land 3. Later games feature him almost exclusively in the anti-hero role, and he seems to have retired as Mario's enemy, even though he does say he is still his nemesis. Wario is not completely evil, but his greed can motivate him to do evil things. Wario is also very aggressive and will turn to violence to get what he desires. He is very hot-tempered as well. Despite lacking common sense, Wario is very intelligent. He has tricked Mario on several occasions and has been shown to be able to fly a plane. He has even built a dimensional teleporter in a matter of seconds. Wario is also shown to be a very poor sport, though the Mario Party games surprisingly portray him as playing fair. He will brag if he wins and he is a very sore loser. He might have a crush on Princess Peach, as well as his friend named Mona, who likes him too. Wario likes garlic and can eat it to become Wario Man. Although he has done many evil deeds, he has done some good and has even gone as far as helping/teaming up with Mario. Despite this, Nintendo seems to still consider him a villain, as he is often an antagonist in special promotions and crossovers, such as during Nintendo Direct where he teamed up with Ganon to attack Nintendo of America's president, Reggie Fils-Aime, and the Super Smash Bros. series where's considered part of the series villain roster (with his trophy in the SSB for 3DS explicitly calling him a villain).

The Wario Brothers
Wario and Waluigi are Mario Brothers' arch rivals and are quite jealous of their glory. Though, Waluigi appears to be Luigi's arch nemesis for unknown reasons. In Mario Sports games, Wario and Waluigi try to defeat Mario and Luigi with their traps but fail. Sometimes they are also helped out by Bowser in Mario Power Tennis in the intro (except Wario and Bowser had a bad relationship with each other). Also the bumbling crooks, Wario and Waluigi tried to rob the Mushroom People's money or sometimes Peach's treasure, acting like criminals, but they were foiled by Mario and Luigi. At one time in Wario Land Shake It! (for the Nintendo Wii) when the evil Shake King kidnapped the lovely Queen Merelda, forcing Wario (and Captain Syrup) to rescue her from certain destruction by shaking the Wii Remote (or tilting it). This was first previewed in the October 2008 issue of Nintendo Power magazine.

Mario vs. Wario
Wario made his first, full non-game appearance in North America in Mario vs. Wario, a comic published by Nintendo Power.

In Mario vs. Wario, Wario sends Mario a letter saying "he wants to catch-up on old times". In actuality, Wario has prepared a trap for Mario, wanting to get revenge on him for Mario constantly "bullying" Wario in their youth; Wario especially hated playing cowboys with Mario, as he would always be the rustler who would be captured by "Sheriff Mario" and locked away. As Mario makes his way to Wario's fortress, defeating all of Wario's minions, oblivious to the fact they are trying to kill him, an angered Wario watches Mario. Eventually, Mario reaches Wario's castle and is confronted by a giant-sized Wario. As Wario begins trying to pummel Mario, the plumber notices a plug on Wario and pulls it, deflating Wario's giant, look-a-like costume.

After hearing Wario call him a bully, Mario says that he didn't mean to "bully" Wario 20 years ago and apologizes. Wario, after hearing this apology, turns over a new leaf, unfortunately, Mario suddenly pulls out a cowboy costume and "convinces" Wario to play cowboys again, with Mario as the sheriff once again.

It was possible that Wario ruled his minions with his iron fist and shows no mercy to his subjects in Mario vs. Wario comic.

Wario also appeared in a second Mario vs. Wario comic, in which he receives an invitation to Princess Toadstool's birthday party. Wanting to get the Princess the perfect gift, Wario rushes-off to buy her a Samus Doll he remembered her admiring.

Unfortunately, when Wario arrives at the store, he learns from the Koopa Troopa shopkeeper that a guy with a "big black moustache" had already bought the doll. Wario, enraged, believes Mario to have been the one who bought the doll and begins to leave, until he notices a nearby, creepy jack-in-the-box. Grabbing the jack-in-the-box, Wario pays for it and wraps it.

Later on at Princess Toadstool's party, Wario makes several unsuccessful attempts to switch the jack-in-the-box with Mario's present. After a lot of effort, Wario does so, only to be shocked when the Princess opens his present and the sinister jack-in-the-box pops out. As the Princess throws the jack-in-the-box away in horror, Wario accuses Mario of setting him up and starts fighting with him.

During this scuffle, it is revealed that Mario's present is also a creepy jack-in-the-box and both Mario and Wario can only look on in surprise and dismay as Luigi gives his present to the Princess, the Samus Doll.

Wario's popularity has allowed the anti-hero to gain his own series and along with it a whole rogues' gallery of his own - unlike Mario's (usually) selfless quests, however, Wario's adventures are always about collecting treasure, getting rich, and are also much more bizarre - often surreal - in nature: some of Wario's more noted enemies are Captain Syrup and Rudy the Clown.

Wario Blast
Wario is also a major antagonist in the crossover game Wario Blast in which the selfish slob finds a portal to Bomberman's world and decides to rob it of its many treasures - putting him at odds with Bomberman: the game is somewhat unique in the fact it's up to the players who wins and they can either root for Bomberman or aid Wario depending on personal taste.

Subspace Emissary
In the Subspace Emissary storyline, Wario is the tertiary antagonist and one of the Subspace Commanders alongside Bowser and Ganon (who both serve as the secondary villains), though he appears have relatively low control over the army in comparison to his cohorts. Wario reason for joining was merely to cause havoc and he actually cares very little of the army's actual objective, so long long as he's allowed to do whatever he wants. After Kirby defeats Petey Piranha, and rescue either Princess Zelda or Princess Peach, Wario will capture the other one. After he successfully capture one of the princesses, he'll retreat before the Subspace Bomb goes off. Later he dispatches Porky Minch to capture Lucas, but after Porky is defeated, Wario personally appears and changes his target to Ness (who had arrive to save Lucas). After Ness was able to dodge all of Wario's capture attempt, Wario went back after Lucas. When Wario attempted to capture Lucas, Ness pushed Lucas out of the way, but gets captured by Wario. Wario is spotted again. He finds Luigi already in his Trophy mode and proceeds to capture Luigi, however this was a trap set by King Dedede. King Dedede managed to take Wario's cargo and take, Luigi, Ness, and one of the Princesses with him. In a desperate attempt to restart his collection, Wario decided to fight Lucas and the Pokemon Trainer's Squirtle, single handedly. However, Lucas and an Squirtle managed to defeat Wario and turn him into a trophy.

Wario was eventually rescued by Kirby, he decided to excate his revenge on King Dedede, back kicking him in the back. But Luigi and Ness defended King Dedede. They told Wario that they were going fight Tabuu and bring world back into order, and that he was welcome to join. So Wario decided to joined the fight all the characters to fight Tabuu.
