Cammie looks like a sweet kid, with her freckles and mechanical rabbit ears and generally bouncy demeanor, but don't be fooled: she's stubborn, swears like a sailor, is sarcastic enough for her whole squad, and has absolutely no patience for being treated like just some kid. In fact, doing so is the quickest way to get on her bad side; whilst she's forgiving enough of her teammates for their occasional slip ups (though she still grumbles, even then), any stranger who makes this mistake receives no such leniency. For example, when investigating the spy situation at De Soto, she was unsure if her judgement of one suspect was being clouded by the fact they treated her like a dumb kid.
She's been reprimanded for her language in the past, most notably by the late Dr. Weller, and has been warned that some people won't take her as seriously when she swears as much as she does. Sometime prior to GL squad's involvement at De Soto, she agreed to institute a virtual swear jar in which she would have to pay Ether credits whenever she cursed, something that was semi-successful in controlling her language, because she does want to be taken more seriously by those around her.
She's an extremely curious and creative person, always eager to learn more about the world around her but especially when it comes to technology and mechanics. She likes to be hands on with the code and gear she's working with and isn't afraid to ask questions about it, even if she doesn't always expect an affirmative answer. Upon receiving her GL suit, she immediately began examining its components and asking questions and later, she shared with Migas her concerns about her Holon's proportions, reacting with delight when he proposed modifications to the frame and sent her the programs she'd need to design such changes. With these tools, she was able to create five highly personalised Holon frames, sets of armour and weapons for her squad that were specifically designed to suit both their personal styles and skillsets.
She's observant, not only remembering things about her squad that enabled her to make such personalised designs but often noticing things that her teammates don't; whilst at De Soto base, she was the only one with the expertise to realise that the use of high pressure valves in one of the suspect's motorcycles indicated that they weren't who they said they were, as the use of such valves was limited to someone much richer than the suspect in question pretended to be. She was also the first one to realise that activity in the GL network was the reason why Nemesis could track them. Coming from a non-military background, she looks at things in a different way to the rest of her squad, which has proven to be vital on multiple occasions.
However, outside of her primary areas of expertise, Cammie often lacks confidence. At 17 and lacking any military experience, she often feels that she isn't keeping up with the other members of GL and is, in fact, holding them back in the field. She struggles with physical skills and aim, requiring a set of aim-assist drones that can be rendered unusable by adverse conditions. After their first encounter with Nemesis, in which she was cut off from the team and her Holon beheaded, she even attempted to artificially boost her confidence and aggression by adjusting the settings of her cyberbrain, in hopes of combatting this. Whilst she learned that this isn't the best way to go about dealing with the problem, she still struggles with it.
This is further exacerbated by her continued, relatively fresh trauma from that first encounter with Nemesis. Whilst she was physically unharmed, the experience was still extremely traumatic as, Holon body or not, she still experienced having her head torn off. In the aftermath she has been plagued by nightmares in which Nemesis comes for her, and she's struggled to talk about them with anyone as she feels as if she shouldn't feel this way when she's physically fine and should be over it by now, because all the texts say that the nightmares will go away eventually. She's only recently opened up to Chase about it, after particularly feeling that she couldn't talk to him as he'd been through much worse, and is still reluctant to tell the others.
One of her methods of coping with this trauma (and the traumas of life in general) is to throw herself into either games on the Ether network, a virtual reality network that spans the globe which she sees as a safe haven of sorts, or into her work. She spends hours late at night either designing things or going into the Ether, which leads people to think that she's simply staying up late gaming for the sake of it, when it's more of a case of her being unable to sleep and needing to ease her mind. Admitting this is something she also struggles with.
She isn't, however, at all ashamed of her interests; her bunny-rabbit aesthetic is consistent across her every-day clothes, her Holon armour and her Ether avatar. She makes pop-culture references and talks about manga, enjoys gaming with her squad and wishes they'd use it as a method of team-building more, and objects to any implication that her interests are childish.
Cammie is, in the end, a teenager who is still learning and developing, who has lost multiple years of her childhood to the loss of her parents, the war, and working off a prison sentence earned doing black-hat hacking. She wants to have fun, but she also wants to be respected for the person she is and the experiences she's had.
