9-Volt
School gets out at Diamond Elementary and 9-Volt skates home to do what he loves best: spinning records and playing classic Nintendo games. He pops a cartridge into a Game Boy from the creamed spinach-color era and goes to work. The game, a parody of the original NES Dragon Warrior, has players using hit points for chances to play classic Nintendo games. In his mind, 9-Volt is a Mega Nintendo Fanboy, he collects everything about Nintendo, included Hardware and Software, of course. 9-Volt lives with his unseen mother 5-Volt and his pet Shaggy.
His microgames are Wariofied versions of NES classics. 9-Volt's series is actually a brilliant example of product placement; each microgame is based on a classic Nintendo game or product, such as the NES Balloon Fight or the Super NES F-Zero. Mario-related games referenced in 9-Volts series include the original Super Mario Bros., Mario Clash, the NES Dr. Mario, Mario Paint and the original Donkey Kong.
Ken the Reporter pops up to interrupt 9-Volt's epilogue with an important announcement: the new Game Boy Advance SP is now on sale in stores everywhere. Our tech tyke leaves in such a rush that his skateboard transforms into a hoverboard.
9-volt also appears in warioware twisted. In this game he is shown to be a troublemaker in school. He also makes friends with 18-Volt. His boss game is a twisted reinaction of the original World 1-1.
Chicken Race, an extra game players can unlock, also features 9-Volt. Two players control either of two feet, which kick 9-Volt or Shaggy on a skateboard. Whoever coasts the closest to the end of the cliff without sailing over it wins.
Later in WarioWare: Touched!, his best friend 18-Volt helps him create Wariofied versions of original NES games.
In WarioWare: Smooth Moves, he shows 18-Volt an old Game & Watch game, but plays it for so long that 18-Volt, forced to merely watch the whole time, grabs the system because he wants to play. This leads to the Game & Watch breaking and 9-Volt kicks 18-Volt out of his house angrily. Later, when 9-Volt witnesses 18-Volt waiting in line to buy a new Game & Watch, they both apologize and become friends again.
