A girl who is always optimistic and will never back down in a fight. She is also sick and tired of people spelling her name as "Arielle" or "Ariel". She may be tiny, but everything is "more than meets the eye". Also, she cannot swim, so she is NOT a mermaid.
If you throw Aerielle in the ocean and tell her to go back to her father, King Triton, you might just cause a murder or at least an attempted murder.
