Redo on Elf. I think that is just her name by now.
The idea of this character is that she is an alien entity inside a human'ish/elf shell in a way, like a way to blend in with humans. I have no idea what else she can do, but she is definitely not a human, elf, or whatever.

Update on the story(8/7/2022): Elf is an alien creature that came from far out into space. Her planet had started to die off, dwindling resources and population. She was soon forcibly sent off the planet by what was her parent figure, in an attempt to save her from their slow demise. Sent off unknowingly on a night a meteor was foretold to strike. Left without knowing such information, days later landed on earth in her UFO( Unidentified Flying Oreo ). Hiding for some time before forming into something human-like to blend in. Now living amongst humans on earth. Very curious of everything around her.
