Rouge is a strong-minded young woman, a fearless, treasure-hunting, ambitious, independent, flirty, ruthless, calculating narcissist who most people see as only caring for herself and her gems. It is shown that Rouge can be referred to a temptress, due to her flirtatious and selfish ways. Her carefree and playful attitude can be fun or even annoying for the others, especially Knuckles. She has a lot of pride and starts to fight dirty when facing a superior opponent, such as Knuckles (when it comes to power) or Tails (when it comes to flight). She can also show a bashful side, such as the time Knuckles saved her life from falling into her doom and became very embarrassed before disguising it with disgust and outrage.

Rouge is also at times a government spy who works for her own good. Rouge has a great obsession for jewels or even anything else that shines or glitters. She has been known to seduce people with her attractiveness to get what she wants. However, she has, on occasion, shown that she can be heroic.Helping to save the planet once. She stopped Shadow the Hedgehog and E-123 Omega from killing each other, and is seen battling Chaotix and Sonic as liabilities to her quest to finding Dr. Eggman's supposed hidden treasure room. When Shadow was injured and needed a place to stay, Rouge helped him. Rouge is often known to switch between the sides of good and evil whether to succeed to get her jewelry or to save the world from danger.
