Sparcium

Sparcium is a substance mentioned in the Sonic Boom television series. It is an elusive type of metal used for construction.

Description
Sparcium is a metal alloy suitable for constructing electronic components, such as microchips and AI processors. It is also very rare, making it highly valuable.

Past
Years ago, Sparcium would be used for the microchip in the Tomatopotamus 2 game cartridges. However, when the Sparcium proved more valuable than the cartridges themselves, nearly all existing copies were recalled and melted down.

Season two
In the present day, Sonic got his hands on a Tomatopotamus 2 cartridge with its original Sparcium microchip, while Eggman would make an Sparcium-based AI processor for FiendBot. When the benevolent FiendBot's AI processor got destroyed, Team Sonic used the Sparcium in their game cartridge to replace it.

Trivia

 * Sparcium's name is a prortmanteau of "Sparse" and the "-cium" prefix.
