Augmented Vision
In addition to a Heads-Up-Display that displays system data, mapping, and allows her to remotely operate her burner smartphone, Sev's helmet has several augmented vision modes, including Light Amplification and Thermal. This is displayed both on the helmet itself, and fed through the neural link if the helmet is attached to the frame.
Ceramo-Composite Armor
On the defensive side, Sev's frame has mounting points for a set of Ceramo-Composite Armor Plates. These provide bullet protection, as well as spreading out impacts and allowing the frame itself to take the blow as opposed to the body within. This is displayed both on the helmet itself, and fed through the neural link if the helmet is attached to the frame.
Exo Frame
Sev is equipped with Kyber-Tec's latest prototype military Exo-Skeleton Frame. Aside from providing enhanced strength capable of lifting 700 pounds, a running speed of 30 MPH, and enhanced endurance, the neural link unit that controls the frame can be used to interface with computers, and the frame itself provides mounting points for a set of armor plates.
Brawling
Sev never had the chance to actually study martial arts, and she can't really go to a dojo. As such, her fighting style mostly relies on her armor to take the blows, and the frame to put weight behind her punches.
Coding
What's a job you can do without ever meeting face to face? Computers! Sev pays the bills by working as a freelance coder and web developer, also having learned her way around a server, which can be very useful when doing 'research'.
Parkour
Not legally existing except under a fake identity makes things like getting a driver's license difficult, and taking public transit is just awkward. As such, when Sev is armored up as Exo-Girl, she mostly gets around on the rooftops, able to run faster, jump higher, and in general be more mobile without getting exhausted.
Safehouse
As someone who doesn't go out a lot and is worried about being found, Sev's studio apartment is equipped with a steel door, and entirely too many locks. It probably wont' keep out another metahuman, but it keeps anyone from trying to break in and steal her stuff. This is especially nessecary given that she's trying to keep a low profile, and lives on the seedier side of town.
The Voice
Someone helped Sev escape Kyber-Tec. She doesn't know who, as she's only ever interacted with them over her headset, and they use some kind of voice masking. They clearly have inside knowledge though, as they have sent her replacement parts, or instructions on how to repair things in the past.
Behind The Mask
In her armor, Sev's a local hero. Without the plate however, she's a teenaage girl with some nasty scarring who makes funny noises when she walks and has lumps under her baggy hoodie. Needless to say, she doesn't enjoy going out unless she has to, and tends to stick close to home when she's not 'suited up'. This has also contributed to her lack of self esteem, and social anxiety that usually manifests in a stutter when she is unarmored and nervous.
Surge Protection
When you're bolted into an exo skeleton frame controlled by plugging it into your brain, power surges can be a problem. Electromagnetic Pulses, or strong electrical currents can knock her system offline and require a reboot, or even knock her unconscious completely.
Who Was I?
During the installation of the Neural Link Unit, the Kybertec scientists weren't too concerned with keeping Sev's long-term memory intact. It's a lot easier to control a girl who only remembers life as Subject EXO-07. There are vague images of a family, but nothing distinct, and those could just be dreams as far as she knows.
