Wario (ワリオ) is a character from the Mario series, who eventually became popular enough to spawn his own side-franchise. He has made several small cameos in the first two Super Smash Bros. games, and has been made a full playable character in Super Smash Bros. Brawl and Super Smash Bros. 4. He is known to be Mario's rival.
When Nintendo launched the Game Boy handheld system in 1989, Gunpei Yokoi's Super Mario Land launched with it. Mario's 8-bit adventure was so successful that one year later, a sequel arrived. Super Mario Land 2: 6 Golden Coins takes place directly after the first game, when Mario comes home after defeating the evil alien Tatanga. When he arrives, he discovers that his castle has been taken over by his antagonistic, greedy counterpart, Wario, and he must retrieve the 6 Golden Coins hidden around the land to get his home back. In the final showdown, Wario was revealed to look very much like Mario himself, except fatter, slightly shorter, and with a big, bulbous nose that had a jagged, pointy mustache jutting out of it. In a three-part battle, Wario uses the same power-ups that Mario had access to throughout the game, and adds his own abilities to the mix. Wario charges at his opponent with his shoulder, and crashes to the floor butt first, which become staple moves for the character in future games. When conquered by Mario, he reverted to a "tiny" form, and escaped out the window to search for better treasures.
And search for them he did, as he landed a starring role in the third game in the series, Wario Land: Super Mario Land 3. It takes place directly after 6 Golden Coins, in which Wario sets out to earn as much gold as humanly possible, so he can buy his own castle and rub it in Mario's face. This game played differently than the first two games, because Wario brought his own style with him. Instead of deploying acrobatics like Mario, Wario relied on his brute strength, and the ability to sport various hats that gave him different powers, such as a dragon hat that spewed fire. He also gained his own villain in this adventure, the equally greedy Captain Syrup, who captured a Genie to use for her own selfish purposes. By the end of the quest, Wario gives both Syrup and the Genie a sound thrashing, and pays the Genie to grant him his castle.
After antagonizing Mario and his friends yet again in games such as Wario's Woods and Mario & Wario, Wario continued to have three more adventures on various Game Boy platforms. In Wario Land II, Wario experiences a case of bad karma when Captain Syrup kicks him out of his own castle and steals it. Wario Land 3 involves Wario doing his first unselfish deed, saving the inhabitants of a music box from the devious Rudy the Clown - on the condition that he gets to keep all the treasure that he earned along the way. In Wario Land 4 he does what Mario had been doing for the last decade beforehand and rescues a princess. Through these games, Wario eventually evolved from the classification of "villain" and earned the title of "anti-hero".
After all these platforming escapades, Wario, now sporting biker gear as opposed to a yellow and purple version of Mario's duds, notices the boom of the video game industry, and decides to take advantage of this craze by forming his own game company. Due to his short attention span, instead of creating a single game of reasonable length, he opts to make over two hundred games, each of them a mere five seconds long. Too short to even be called "minigames", they were dubbed "microgames". Finally, since he was too lazy to make all these games himself, he hires a handful of his fellow residents of Diamond City to do his work for him, among them the feisty multi-talented Mona, and the Nintendo superfan 9-Volt. Thus, the WarioWare franchise was born.
Wario has also made appearances in a great number of Mario spin-offs, including the Mario Kart and Mario Party games, as well as a large number of Mario sports titles. In these titles, Wario is no longer evil, but more of a bumbling comic relief. His rumored brother bent on bothering Mario's brother, Luigi, is soon revealed, being named Waluigi.
Due to Wario's popularity, he was one of the newcomers in Super Smash Bros. Brawl. Instead of being added as yet another Mario character, Wario enters the arena representing his own Wario franchise.
Wario did not appear in the original Smash in any capacity. A popular rumor though claims he was planned to be playable in the game along with Bowser, King Dedede, Mewtwo, and many other characters, before being cut for space/time constraints. However, unlike the aforementioned three characters, no definitive official source has ever been found that proves Wario was ever planned to be included as a playable character.
As a color scheme
According to the official Melee poll, Wario was the 3rd most wanted character (with 66 votes) from the Mario series for the game, after Bowser (169 votes) and Princess Peach (66 votes, bumping Toad (27 votes) into 4th place). However, despite Wario's popularity, Sakurai passed over him, as he did not want to include three newcomers from the Mario series. Later on when Sakurai decided to add clones to the roster, he initially considered Wario as a clone of Mario, being slower but more powerful, but again passed over Wario, as Sakurai felt Wario "deserved better", and that Dr. Mario was a more fitting choice.
As a color scheme
Wario is once again referenced by a costume with his colors being sported by Mario. And like before, this costume change has no effect on gameplay. The only changes are his M is blue and the rivets and buttons are white.
"An old acquaintance of Mario's. His failure to seize Mario's castle has fueled Wario's desire for a palace of his own. Wario has herculean strength and can do things that even Mario can't imitate. His unexpected skills include a talent with items and the ability to assume many roles, among them a snowman, a zombie, and a bat.
(Super Mario Land 2: 6 Golden Coins, 11/92)"(GB)
Wario is a playable character in Super Smash Bros. Brawl. His movelist draws inspiration from WarioWare, with the exception of his Forward Smash which is his iconic shoulder barge from the Wario Land series. As a fighter, his moves and maneuvers seems to be very erratic and sometimes comical in nature, ranging from a dash where he appears to be dancing (similar to Mr. Game and Watch's movement), to a fart attack that builds up in power as time passes. While entertaining to see, these features are often only handled well by veteran players. Mario still has a Wario color scheme and Wario still bears his WarioWare biker suit from his own series, as well as his original Mario-style suit. His Final Smash is Wario-Man, where he consumes garlic turning the already insane anti-hero into a more powerful caped "superhero".
"Mario's self-styled rival. He loves money and gross humor. He often sets out in search of hidden treasure. His bold moves come from his superhuman strength and are completely different from Mario's moves. Aside from adventuring, he's also the chairman of game maker WarioWare, Inc. Its franchise game is WarioWare, Inc.: Mega Microgame$."
Wario was leaked on September 11, 2014 by Japanese players who were able to buy the game early, with Wario being available as an unlockable character. Prior to his reveal, the Nintendo 3DS eShop listed Super Smash Bros. for Nintendo 3DS on a list of games that include Wario, though it was later removed when this was made public. A supposed report from the Australia Classification Board provided further evidence for Wario's inclusion, as his design and Wario Waft attack apparently contributed toward the game receiving a PG rating.
Wario's moveset is mostly unchanged, with the exception of him having his up and side smash attacks replaced with different moves. With the latter's removal, the Wario Land series is no longer represented in Wario's abilities. Wario's animations now are far more fluid, which is best exemplified with his new running animation. Unfortunately, Wario lost palette swaps, as he now only has 8 palettes (4 biker, 4 overall), like every other character, as opposed to his 12 color swaps in Brawl. He is now an unlockable character.
