Rouge is a strong-minded young bat, 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 in Sonic Generations 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 other characters of the series, 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. She can also be a bit of a hypocrite, especially in regards to thefts. This is especially evident when, after witnessing the Master Emerald being stolen, she refers to the one stealing it as a thief despite the fact that she herself had stolen it from Knuckles earlier, something Knuckles even noted by saying "Look who's calling who a thief!"

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

You can base this interpretation on her past voices. If not, something flirty yet strong.
