Mrovian fusion device

The Mrovian fusion device is a piece of technology developed by the Mrovians. Like the, the device's purpose is fusing a pair of beings into a single, more powerful entity.

Overview
The Mrovian fusion device takes the appearance of "a metal square plate about the size of [ Cuber's ] palm with a blue crystal in its center." To use it, one being must clip the device onto the back of his neck, and then make eye-contact with another being. The device will then pull the two beings together into an energy sphere that engulfs the two of them before completing the fusion process. Unlike the Potara Earrings and the, which multiply the power of both fusees hundredfold and decrease the multipliers of super saiyan levels, the Mrovian fusion device only multiplies the power of both fusees tree times but also maintains the original super saiyan multipliers.

History
The Mrovians began experimenting on the fusion device on the planet Typhon, which resulted in the deaths of all scientists that were involved in the experimentation. When Cuber arrived on Typhon to investigate and was then beaten to near-death by Yuki only to be temporarily saved by Ledas, Quoeyg told Cuber of the fusion device. Cuber eventually found a single fusion device in the ruined labs, and then fused with Ledas, forming Cubas, who was able to defeat and kill Yuki.
