I like all of Rouge's voices that she has had throughout all of her appearances. So take inspiration from any of them!

Rouge is a strong-minded young woman. A fearless, ambitious, independent, flirtatious, greedy, calculating narcissist who most people see as only caring for herself and gems. It is shown in Sonic Generations that Rouge can be referred to a temptress, due to her seductive ways. Her carefree and playful attitude can be fun to some characters, like the easygoing Sonic, or annoying for others, like the gruff Knuckles. She has a lot of pride and will fight dirty when facing a formidable opponent, such as Knuckles (when it comes to strength; hindering his sight in a dark tent). She can also show a bashful side, such as the time Knuckles saved her life from falling to her doom and became very embarrassed before concealing it with disgust, outrage, and ingratitude. 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 the echidna even noted by saying "Look who's calling who a thief", and in Grand Metropolis stage when she calls robots energy thieves.
