Rusty rose

Rusty possesses Amy's common sense, desire for efficiency, and fighting ability, but was stripped of her natural compassion for others, nor did she have Amy's playful nature. She was initially shown to be cold, efficient, and aloof, and possessed a loyalty for no one but the Chaos Council.

Under their control, she showed little to no mercy toward others, as shown when she readily subjected Sonic toward incredibly strenuous trials and was prepared to execute him in spite of his pleas, or when she coldly showed the tortured Flicky that fueled her body, for seemingly no reason. She continued to display this in combat, where she engaged in battles with either rebels, or when she was turned against the Eggforcers, with a cold expression on her face, and little to no words spoken.

She has also shown willing to call out others when they're wrong, as demonstrated when she called Sonic's bluff when he attempted to feign ignorance to Mr. Dr. Eggman's questions regarding the other Prism Shards, by displaying the footage of Sonic talking to Knucks, or when she freely corrected Sonic about her real name on multiple occasions.

Whenever she is tasked with a mission, she would execute it as efficiently as possible. She would not waste time when engaged, as shown when she freely retreated from the battle against the Rebels, when told by the Council that they had captured Nine. Even when she hesitated after seeing Black Rose, she merely stated that they did not have to "waste time" with them, and instead focused on securing the Devil's Lighthouse. This can be dialed up at points, as well, when she continued to order more Eggforcers to stop Dread from taking the Prism Shard for himself, as the battle heated up.

Despite her cold nature, Rusty has been shown to possess emotions which she kept for the most part suppressed. She is capable of shock and confusion, as shown after she saw Black Rose for the first time and again after she was defeated and taken captive by the pirate crew. She can also demonstrate irritation and frustration at times, as shown by the continuous acts and quips of Sonic, such as the instance where she growled after he had destroyed a group of Eggforcers. Rusty has displayed positive emotions as well with various instances of her smiling and expressing some form of enjoyment.

After being betrayed by the Council and left at the mercy of Dread and his crew, Rusty experiences more glitches before eventually deciding to help the crew so they can fight the Chaos Council, becoming a member. After this, she forms a bond with her pirate counterpart and her blind sense of loyalty appears to diminish, even more so after Dread betrays the whole crew. No longer does she compliantly follow all orders given and now warms up to those who genuinely help her, willingly working alongside them.
