Intelligent and highly capable of independent thinking, she uses whatever means she believes necessary to achieve her goals. Still, she has a somewhat playful attitude towards her job that makes her personality similar to Scaglietti's. She always puts an act when near her sisters, always controlling her own words and actions, as she apparently has a side that she doesn't wish them to see. Quattro differs a lot from her sisters when it comes to her own personal opinions, especially those regarding Lutecia. Overall, Quattro is extremely similar to Scaglietti, especially when she stops hiding her true personality near the end of StrikerS.
