18-Volt is 9-Volt's big brother who has failed Kindergarten multiple amounts of times. He has a very large stature and appears to be a teenager. 9-Volt and 18-Volt both appear to share the same love of video games, but 18-Volt seems to be more inclined to music, as he usually can be seen carrying a stereo as well.

WarioWare: Twisted!Edit

Spintendo Classics Edit

18-Volt is the new student at Diamond City Elementary where 9-Volt attends. When the teacher asks him to tell about himself, 18-Volt plays loud music, which is his hobby, angering the teacher.

As 18-Volt walks home depressed, 9-Volt asks him if he can hang out at his house, and 18-Volt agrees. 18-Volt wanders around 9-Volt's house. 9-Volt gets 18-Volt to play the Nintendo Entertainment System together.

The Volts have been playing for a long, long time until they get caught by 5-Volt, 9-Volt's mother, who sends 9-Volt to bed and 18-Volt to his home.

WarioWare: Touched!Edit

Retro Action Edit

9- and 18-Volt buy a game called 36-Volt Man at their local game store and play it at 9-Volt's House. Then they celebrate their win by dancing, but it gets so late that they fall asleep.

The Volts wake up the next morning. They look at the clock and realize in shock that they're late for school, and rush to it.

WarioWare: Smooth MovesEdit

In "The Multiplayer Test" 9-Volt is hanging around with 18-Volt at 9-Volt's House. 18-volt sees a Game & Wario (a dual screen model) and mistakes it for a Nintendo DS Lite. After 9-Volt corrects 18-Volt, 18-Volt becomes overly excited about the new vintage game. Wanting a chance to try it, he tries to take it from 9-Volt's hand, ripping the system in two. 9-Volt, very agitated, kicks 18-Volt out of his house. That afternoon, 18-Volt searches for a gaming specialty shop. He finally finds one, and the player must complete a Microgame challenge based on Nintendo games. After completing, 18-Volt finds another Game & Wario  to find that 9-Volt is doing the same. 9-Volt stares intently at 18-Volt, then forgives him, saying "You will ALWAYS be my Player 2!" Then, "The Multiplayer Test" is over.

WarioWare: D.I.Y. ShowcaseEdit

In the Store, 18-Volt's stage can be played via the Game Blender. 18-Volt's stage screen is an 8-bit game paryoding 1943 (titled "JET 18-VOLT") and staring 18-Volt as a fighter jet. For every victory, he defeats an armada of Fronks that spell out the number of games, and for every faliure, he gets blown up. After every Boss Stage, he catches up to 9-Volt flying in a spaceship that resembles his helmet and holds out his hand in friendly embrace but slaps 18-Volt's hand away maliciously and flies away. (Fun Fact: In his stage description, he says: "I'm 18-Volt, with twice of the power of that other guy you might be thinking of!")
