Surge possesses Sonic's indomitable and free spirit, albeit in a twisted and sinister way. She is a roguish speedster with an arrogant, cocky, and hot-tempered disposition, taking great pride in her prowess and bragging at any given opportunity. She is also fearless and bold, rarely showing any form of worry or concern, even in situations that are troublesome or possibly beyond her capabilities. When push comes to shove, however, she tends to give in to anger, causing her to become a more volatile force. Believing force to be the answer to everything, Surge is convinced that she can defeat any opponent and overcome any obstacle getting in her way with pure strength and speed.She is likewise brutal, somewhat bloodthirsty, and highly aggressive,expressing great eagerness to fight and cause chaos and destruction.When working with Dr. Starline, she would persistently demand to go on missions and even grab him by the collar,threatening him when unable to get her way. Now that Starline is dead she and Kit are free to do what they like.Surge prefers open conflict over covert plans, no matter how effective the latter might be.Notably,she would willingly abandon a plan focusing on stealth in favor of an open assault,assured that she would be able to defeat any attention she would attract,even while in enemy territory.She is likewise fiercely independent and irreverent to authority,like Sonic,meaning she prefers to do things her own way.As such,she is perfectly willing to abandon a well-thought-out plan in favor of following her own whims.Unlike Sonic,however,she shows little to no concern for any negative consequences her roguish behavior may have on herself or others.Despite this,she is willing to listen to others' ideas when she admits that she does not really have much of a plan of her own to proceed with,which makes her more open to suggestions from Kit. Like Sonic,Surge shows a great deal of attitude when facing off against foes,namely by taunting and mocking them.However,this is out of mean-spirited arrogance and malice as opposed to the carefree playfulness Sonic demonstrates.She is likewise brash,careless,and impatient,which are qualities that stem from her explosive temperament and sense of superiority,unlike Sonic,whose same qualities stem from his positive attitude and confidence.As such, she is prone to facing everything head-on,making her extremely reckless and dependent on support from Kit(despite what she may believe).She also hates being deceived and will seek out terrible retribution against those who have wronged her,although this is more out of personal vengeance than a sense of justice.rather petty Despite her punkish attitude and overall simple-mindedness,Surge does have her moments of insight.

shares Tails' kindness and modesty, but with his positive traits turned on their head. He is defined by a soft-spoken, somber, withdrawn, and timid attitude, with very little in the way of individuality, as he is programmed to be subservient to Surge and satisfy her wants and needs. He speaks politely and formally, addressing others as "sir" or "ma'am". Kit is also quite nervous and often stutters when he talks. Despite his reserved demeanor, though, he is capable of moments of extreme emotions: when he thought Surge had received lethal injuries, he snapped into a sorrowful rage and would scream loudly as he took brutal revenge on her attacker. His connection with Surge is so strong that when he thought she was dead, he instantly fell into a deep depression. Similarly, his desire to be of assistance is so strong that when he learned Sonic was in danger, he instantly ran to help him, regardless of his own physical and mental state. Unlike Surge, Kit possesses a keen and analytic mind that prompts him to look before he leaps. As such, he is full of ideas and creative solutions that do not rely solely on brute force, and prefers sticking to the plans that have been laid out instead of recklessly charging in, having noted that plans are his thing.However, he appears to lack self-confidence and hold a low opinion of himself (even considering himself as something akin to an object or tool for his partner to use) due to his dependency on Surge, having refused to take part in operations that involves vital elements of support. Even when he comes up with a complex and clever plan himself, he always needs assurance from his superiors to go through with it. His sorrowful attitude also prompts him to seek validation from others, and Surge and Starline’s constant mistreatment caused him to have emotional breakdowns. Despite his timidness and intelligence, Kit has shown a streak of sadism, resentment, and callousness, especially after believing that Sonic had lied to him about Surge's death. While first fighting Tails, he commented on how much water and time was needed to drown someone, and he later coldly rebuked Sonic for his actions and attempted to bury him and his allies alive. He has also shown himself to be manipulative and hypocritical, as he hates Tails for what he sees as the two-tailed fox's dishonesty yet is quite devious himself.
