Xenor Krell

When Amy Rose and Tekno stumbled across Xenor Krell in Casle Grimm she told them that she was on a quest to recover the stolen Ultragem which she needed to power her people’s cities. Since Xenor had been damaged by Serpentia Amy went on ahead and recovered the Ultragem for her, but when they presented it to Xenor she revealed her true colours as a thief. Xenor planned to use the Ultragem to conquer the world and enjoyed playing with Amy Rose and Tekno, she even destroyed Serpentia with ease. However Amy Rose defeated her by playing on her vanity, changing the castle into Solid Silver and then using the Silver to reflect the Ultragem’s rays back at Xenor who was reduced to mist along with the gem.
