9-Volt & 18-Volt

9-Volt (ナインボルト) and 18-Volt (エイティーンボルト) are elementary school boys who live Diamond City in the WarioWare Series. Both share a love for video games, specifically "old school" Nintendo ones from the NES era.

In Rhythm Heaven
18-Volt and 9-volt appear in Rhythm Heaven Megamix in the Challenge Train course Wario...Where?, in which they replace The Wandering Samurai in Super Samurai Slice, with 18-Volt wielding a katana while 9-Volt piggybacks on him. Instead of a maiden, they must rescue Sal Out, who was kidnapped by evil creatures.
