This is Lilaze, an Elemental Warrior. She is a fusion of both Blaze the Cat and Lilac the Dragon. As such, she possesses the attributes of both Fire and Water. Lilaze can combine both elements together in an attacking finisher move named Equinox Blast! As a result of her Fusion, Lilaze's emotions are greatly enhanced.
Lilaze has an accompanying sword dubbed The Equinox Blade! This Sword helps stabilize her elemental abilities. Its design is specifically for Lilaze personal use only. Therefore, its enchanted elemental prowress will not attune to or for practically anyone else, thank you.
