Zeonizers were interlocking, wrist-modunted devices that harnessed the energy of the Zeo Crystal and empowered the Zeo Zords. The Zeonizers were created for the former Mighty Morphin Rangers by Zordon to replace their Power Morphers. These devices were the first wrist-worn morphers and utilized the Zeo sub-crystals in a similar manner to the Power Coins.
