There's no specific way to write a character. This question is completely up to you.
Just ask yourself:
What kind of supernatural?
Can they read minds?
Can they shape-shift?
You make the character.
It can be a 13 year old boy who doesn't even notice anything strange about himself or a 23 year old woman who's been wondering why she can hear other people's thoughts.
Answer:
The thesis statement does all of the above.
Why:
A thesis statement appears in the middle or end of the introductory paragraph of a paper, and it offers a concise summary of the main point or claim of the essay, research paper, etc. It is expressed in one sentence, and the statement may be reiterated elsewhere.
Hope this helps!
