Being cynical and angry, Loona is generally disinterested in the matters that go on around her. She is rude and apathetic towards her colleagues. She also possesses a short temper and is emotionally troubled, as a simple questioning about eating Moxxie's lunch led her to kick a baby in frustration. She is very apathetic towards the suffering of others, as seen when Millie called her and told her that she had been stabbed, but Loona just hung up on her.
