9-Volt

9-Volt is a major human character in the WarioWare series. He is a Nintendo fanboy and collects everything about this company and loves to play video games. 9-Volt lives with his mother 5-Volt and his pet Fronk in their house in Diamond City and attends Diamond Elementary. He debuts in WarioWare, Inc.: Minigame Mania as one of Wario's friends who helps him produce microgames.

Since WarioWare: Twisted!, 9-Volt always stars together with 18-Volt in the WarioWare series, who becomes one of 9-Volt's best friends in this game.

''WarioWare, Inc.: Minigame Mania
Firstly, 9-Volt could be seen in the intro of WarioWare, Inc.: Minigame Mania, where he is called by Wario to join his "company" WarioWare, Inc. and to produce microgames for his upcoming game. Like Wario's other friends in Diamond City, 9-Volt agrees.

In 9-Volt's own story, the school was out and he skates home with his high-tech skateboard SK8. At the house, 9-Volt gets into his room and plays with his mixing console. 9-Volt says "Hello" a few times and with the help of the machine he imitates the voice of Jimmy T. or at least a similar voice while saying it. 9-Volt's oversized Game Boy answers him with "OK". Then 9-Volt makes music with the mixing console and spins records on it. Some kind of grabber came out of the Game Boy and pops an over-sized cartridge into it.

Later, while 9-Volt still spins records, Ken the Reporter appears and announces that the Game Boy Advance SP is on sale in stores. Quickly, he leaves the house and his skateboard transforms into a hoverboard. With that, 9-Volt hurries to the next store to get the new handheld.

9-Volt also made a short appearance in the ending story of the game, where Wario represents his employees in the WarioWare headquarters that they wouldn't get anything of the money he earned with the game he and his friends makes and then he escapes. 9-Volt is in shock, but like the other employees except for Mona, he didn't chase after Wario. This suggests that both 9-Volt and Mona have a strong friendship with him (though in hiss case, it might have been his fanboy tendencies).

9-Volt is featured in four unlockable minigames in WarioWare, Inc.: Minigame Mania. In SkatingBoard, he appears as the protagonist of the game and has to avoid obstacles and red birds with his skateboard. In the two-player mini-game VS Chicken Race, 9-Volt is the character of the player who has to use the, while the other player's character is a Fronk, possibly his pet. 9-Volt also makes an appearance in the minigame taken from Mario Paint, Fly Swatter, where the Spiny appearing in the congratulations sequence has been replaced by him. The minigame Paper Plane features 9-Volt as one of the characters looking through a window and telling the current flight time.

WarioWare, Inc.: Mega Party Game$!
In WarioWare, Inc.: Mega Party Game$!, 9-Volt hosts a television show called Super Show. There he uses a mixing console again and a Game Boy Advance with arms and legs that states "OK" in a similar way to the Game Boy in the prior game. After 9-Volt's entrance, Kat and Ana followed.

9-Volt is one of the ten selectable characters in the multiplayer games in WarioWare, Inc.: Mega Party Game$!.

''WarioWare: Twisted!
In the intro of WarioWare: Twisted!, 9-Volt comes along with Mona to Dr. Crygor's Lab. There, Dr. Crygor tries to fix Wario's broken Game Boy Advance with his invention, the Gravitator. But it had no buttons anymore after the repairing, instead of that the player has to move the system to move the character in the game. 9-Volt and Mona try it out and enjoy it. Wario gets the idea to make a new WarioWare game involving this style of gameplay.

9-Volt is shown to be a troublemaker at school in this game. In his own story, a new student named 18-Volt came into his class. On his first day at Diamond Elementary, the teacher asks 18-Volt what his hobby is, to which he responds by taking out his boom box and playing loud Rock 'n Roll music.

18-Volt got in trouble for this and after school he heads for his house broken-hearted. However, 9-Volt stops 18-Volt and states that he likes his music. The two of them become fast friends and he invites him over to his house. When they got there, 18-Volt is ecstatic to see that 9-Volt has an NES and the duo spends a lot of time on playing on the system. However, eventually his mother 5-Volt tells her son and his new friend to cease.

At night, when 9-Volt has to sleep, he furtively plays with his Game Boy Advance SP under the bedspread, but his mother catches him.

''WarioWare: Touched!
In WarioWare: Touched!, 9-Volt and 18-Volt go to the Toy Express to get a copy of the coveted new GameCube game, 36-Volt Man. He snatches one and shows it happily to him, who carries his boom box on his shoulder. Curious about their new game, the two friends quickly return to 9-Volt's house, on which he uses his SK8 to reach it. On their way, they pass the alien Orbulon who runs after his flying spaceship.

At the house, 9-Volt and 18-Volt play far into the night and reign victorious in the game. To celebrate their success, he spins records again, with him dancing behind him and his Nintendo consoles in front of him. 9-Volt's mixing console features moving Mario and Luigi figurines, but it got so late that the two gamers fall asleep.

In the morning, when they wake up, it's already 9 o' clock. 9-Volt and 18-Volt are in shock about the fact they are late and hurry to school.

''WarioWare: Smooth Moves
9-Volt is visited by 18-Volt again in WarioWare: Smooth Moves. There he showed a Game & Watch handheld console to his tall friend and plays with it. 18-Volt mistakes it for a Nintendo DS Lite at first. He wants to see more of the console and gropes it, but 9-Volt still has the console in his hands and informs him that he is still playing, but he couldn't wait and the Game & Watch broke in two halves. He gets mad and orders 18-Volt to leave his house.

Now 18-Volt has a bad conscience and tries to find a new Game & Watch for his friend. He first looks in Toy Express but they didn't have what he searches for. After leaving the store, 18-Volt notices another store where some video game fans line up. He got into the store and the owner of the shop, Shop Manager Iwata, does coincidentally have the searched Game & Watch on offer. 18-Volt reaches for it, but surprisingly 9-Volt does the same. The friends face each other and they both excuse each other for their mistakes. 9-Volt tells 18-Volt that he will always be his P2 (Player 2) and all goes well after that.

''WarioWare: D.I.Y.
In WarioWare: D.I.Y., a game called Super 9-Volt shows up in 9-Volt's stage. It's a spoof of Super Mario Bros. and stars him rather than Mario. 9-Volt, skateboarding, hits a Question Block shaped like a Famicom cartridge every time a microgame is won.

9-Volt, along with Mona, Jimmy T., Orbulon, and Ashley apparently left WarioWare, Inc. to work for Diamond Software in this game. Though the reason they switch companies is unknown, various residents of Diamond city consider possibilities in the DIY Forums feature of the game.

18-Volt, who continues working for Wario, appears to view 9-Volt as a rival after his departure, as suggested by his role as a boss in his game (as well as their interaction after the boss game is completed) and his greeting to the player where he insists that he works at "twice the power as that other guy you might be thinking of".

Microgames
9-Volt comes with his own set of microgames in all games of the WarioWare series. Between WarioWare: Twisted! and WarioWare: D.I.Y., the games are always provided by both him and 18-Volt. However, it isn't known how much he shares in the creation of the games. For example, in WarioWare: Touched! 9-Volt says "our games", but in WarioWare: Twisted! he just speaks about "my games" in the character select menu, plus 18-Volt isn't even mentioned by name in the menu.

The microgames are based on products of Nintendo, mainly on game software and hardware, but also on merchandise from the time before Nintendo becomes popular as a video game company. Microgames based on the Mario series are featured in every WarioWare game.

For WarioWare, Inc.: Minigame Mania, 9-Volt creates microgames of the Nintendo Classics genre. The games involve various Nintendo products from the 1960s up to the 1990s. WarioWare, Inc.: Mega Party Game$! does also feature his Nintendo microgames, plus a multiplayer game made by him, Card-e Cards, which refers to a Nintendo product as well, in this case, the e-Reader.

In WarioWare: Twisted!, the microgame set of 9-Volt and 18-Volt is called Spintendo Classics. As an exception all microgames are only based on NES games in this game. While the microgames of most of the other developers involve a particular style of gameplay per developer, the microgames of him and him require all kinds of spin techniques.

In WarioWare: Touched!, the name of 9-Volt and 18-Volt's set of microgames is Retro Action. The choice of Nintendo products is much more versatile than in the prior game again. Also newer products from the 21st century are featured. The microgames include all kinds of ways of using the stylus and also the application of the microphone, while the most other microgame sets involve a particular technique again.

In WarioWare: Smooth Moves, 9-Volt and 18-Volt's set of microgames involve all possible forms. Considerably more microgames are based on more recent Nintendo products. An example is Brain Age, which is based on the Nintendo DS game Brain Age: Train Your Brain in Minutes a Day!

In WarioWare: D.I.Y., 9-Volt returns to his original role by going solo, while his friend 18-Volt is granted with his own microgames in WarioWare: D.I.Y. Showcase. Despite this, their microgame stages are both Nintendo themed. Akin to Smooth Moves, 9-Volt's microgames adapt to more recent Nintendo products such as Wii Fit.
