This is a cyber-punk character named Dr. Prierie, who discovered and extensively researched about cyber-elf that is sentient pure energy capable of powering automated robotic creatures or used as weapon (like a magic spell) against enemies.
The sprite consists of idle cycle, attack mode (i.e. where she bombards cyber-elf towards enemy or awakens robotic creature to assist her mission) and locomotion mode (i.e. she is able to float while travelling with her cyber-elf.
Her cyber-elves exist in electric, ice and flame forms, which she could interchangeably apply in her battle. These cyber-elves produce shots in their respective forms to inflict damage to targeted enemies.
