Electric Rice Cooker

An ordinary kitchen appliance repurposed as a containment vessel for the Evil Containment Wave technique, most famously used to imprison King Piccolo for centuries. The Electric Rice Cooker is, on the surface, nothing more than a common kitchen appliance.

However, it gained legendary significance when it was used as the containment vessel for the Evil Containment Wave, a sealing technique designed to trap powerful evil beings. By affixing a special ofuda talisman to the cooker's lid, the vessel becomes capable of holding even the most dangerous demons indefinitely. Master Mutaito first employed this method against King Piccolo, sacrificing his own life to perform the Evil Containment Wave and seal the Demon King inside a rice cooker.

Master Mutaito first employed this method against King Piccolo, sacrificing his own life to perform the Evil Containment Wave and seal the Demon King inside a rice cooker. Master Roshi then threw the sealed container into the depths of the ocean, where King Piccolo remained imprisoned for hundreds of years.

The centuries-long imprisonment ended when Emperor Pilaf discovered the cooker and freed King Piccolo, hoping to use the Demon King to achieve his own ambitions of world domination. After King Piccolo was freed, both Master Roshi and Tien Shinhan attempted to use the Evil Containment Wave with new rice cookers to seal him again.

The Electric Rice Cooker first appears in Dragon Ball Episode 102. In the manga, it debuts in Dragon Ball Chapter 135. An ordinary kitchen appliance repurposed as a containment vessel for the Evil Containment Wave technique, most famously used to imprison King Piccolo for centuries.
