The Amazon Gem is a vital gem to Ceaira in the series for many reasons. One of the three most important reasons was that she showed Ceaira and Aquilia that the Kayo Gems had fled to Reidenton, which was where they had moved to two months after the gems escaped. The second reason is her power to trap her opponents in her vines. The vines can be plain, covered in flowers, or in spikes. Amazon's form is a young woman completly dominated by the color green.
Ceaira kept her identity a secret as she confronted Amazon, who had Sakura, Li, and Madison trapped in the vines. Freeing them with Firey, Ceaira herself became trapped herself when Amazon turned on her. Sakura used the Sword Card to free her, then Ceaira attacked Amazon with Firey before sealing her. When summoned, it can either appear only as vines or the woman can appear with the vines. The best combination involving her is with Firey and Watery to form the cage used to trap Windy later on.
