Miraculous ocs

i have an oc, her name is celine delacour. she has the miraculous of the bat and the jewelry is a headband, which gives her the ability of flight, her power is called echolocation and it allows her to find villians easily with sound pictures, and to transform she says "chiro (short for chiroptera the scientific name for bats) open my wings" and to detransform "chiro close my wings". more on celine, she is 15 years old and used to lie, cheat, and steal to get what she wanted, mainly due to her family being on tight strings and couldn't afford things anyway else. until someone saw the good side in her, and that someone was marinette. marinette could tell celine wasn't being true to herself and only lies, steals, and cheats just to keep her family afloat, not because she was a cruel person. so once they became friends she gave celine the bat miraculous and that shifted her perspective on life and now she strives to be a better person than she was. her closest friends are marinette, adrien, juleka, luka, and rose. still kinda working on her story though and would love some suggestions.
