Illuma Shield

The Illuma Shield Power Pack, simply called the Super Plasma Shield in Japanese version of Sonic X, was a device created by Dr. Eggman.

Description
The Illuma Shield allowed the wearer to summon fields of plasma around themselves and utilize energy blasts like lightning to strike foes. It was worn by the Metarex commander, Yellow Zelkova when he battled with Sonic the Hedgehog and his friends, mainly Knuckles the Echidna. With it, he could deflect all his opponents' blows when it was active, but thanks to Sonic's quick thinking, the Illuma Shield was put out of action by channeling the electrical currents of lightning into Zelkova's mechanical body and the power pack, reducing both of them to scrap through the sheer power.
