Here we have another character for an original universe by PowerToLePotatoYEET

My comments will be in bold

Basics and grounding

Sounds interesting, but as always when introducing new concepts make sure they're well explained and developed.

Character information

Considering this seems to be a medieval time period, I don't think bright hair colours were a thing, but since there's superpowers in this universe you don't exactly have to obey to reality.

This is fine but maybe add some more hobbies and write some more details about her personality.

Relationships

These are interesting, but she make sure that they're well represented in the story and that they're not overdone too much.

Backstory

As long as the personality change is well explained and drawn out long enough to be believable, like a downward spiral, then this should be believable. Again, make sure this is well displayed in whatever piece you write.

Other

This works since she is trained with swords

Stats

These stats work, just make sure that the changes are well shown in her story.

Final thoughts
This character seems interesting and well thought out, some further development and details could really push this character to the next lever though. I actually like the sound of her, so good job!
