Arianna has a very complex array of emotions, mostly maintaining her tough, overconfident, and arrogant, girl attitude in front of people and bottling her emotions up inside of her. Upon first greeting, she comes across as blunt, crass, rude, selfish, impulsive, sarcastic, and incredibly bitchy, and more than once has been described as 'saying whatever she wants'. Yet, she has a heart and sometimes cannot bear the emotional burden of some events, such as reliving the suppressed memories of seeing her parents death, finding out she has a twin brother, when the Coven ganged up against her, accusing her of being reckless, dangerous, and mostly bitchy.
At some points she appears to be caring and sometimes nice, and despite her bitchy attitude towards the other members of her coven, she's loyal towards them, her aunt, and others she cares about. She also appears to have inherited traits from her parents, such as being brave, emotionally strong, and determined.
Arianna is a beautiful teenage girl with olive toned skin, green hazel eyes, and long, dark hair which she mostly wears straight, but will sometimes wear it wavy. She has fine cheekbones and full lips, which are pale pink. She is quite tall, standing at 5'8. Despite not caring what others say about her, she was once referred to as "one of the prettiest girls in school" by a jock and even Leo has once commented that 'she has pretty eyes and a nice smile'. She often wears dark makeup, dark coloured clothes, and usually wears a leather jacket, boots, and goth-like dress or skirt, however there has been times where Aria has opted for more 'girly' type clothes, floral skirts, shorts, blouses and denim jackets.
