Illuma Shield

The Illuma Shield Power Pack, simply called the Super Plasma Shield in Japanese, was a device created by Dr. Eggman that allowed the wearer to summon fields of plasma around itself and energy blasts like lightning to strike foes. It was worn by the Metarex commander, Yellow Zelkova to do battle with Sonic and his friends, mainly Knuckles the Echidna. With it he could deflect all his oppontents' blows when it was active, but thanks to Sonic's quick thinking, the Illuma Shield was put out of action by channelling the electrical currents of lightning into Zelkova's mechanical body in the power pack, reducing both of them to scrap through the sheer power.
