Hydraulic Hannah
Background
A few years ago, a story briefly made the news about one Special Agent Hannah Vane going berserk and turning on her employers. Allegedly suffering a severe cyberpsychotic break, she thoroughly destroyed the Crey laboratory she had been assigned to as security detail, killing several other personnel and causing millions of dollars in property damage before disappearing. To this day there is a warrant out for her arrest, and Crey offers a standing reward for any information leading to the rogue agent's capture -- although with the company and the PPD both having much bigger fish to fry, this is not loudly advertised.
These days, she is known as a small-time, street-level hero under the moniker 'Hydraulic Hannah', unlicensed and laying low, with a hardline stance against ever killing again. She makes occasional appearances in the underground cage-fighting circuit, mostly squaring off against other enhanced humans, and sometimes shows up in the Paragonian club scene and the local augmented community.
Powers
Hannah meets the classification of 'heavy cyborg', having had roughly sixty-five percent of her body mass replaced. Her suite of augmentations is geared to power and durability over speed, with four full cyberlimbs, heavy subdermal armor plating, a spinal casing, and an implant that filters out pain. What remains of her skeleton has been reinforced, both to withstand greater blows and simply to keep the weight of her limbs from causing dangerous wear on her bones. Powerful hydraulics give her limbs mildly superhuman strength.
Additionally, Hannah has several much more minor implants, such as cybereyes with near-infrared vision, and a very basic neural interface jack, which lacks wireless capability for security reasons ("can't hack what you can't connect to"). Her ware is good-quality but not startlingly advanced, composed mostly of high-grade surgical steel, plastic, and other not-so-super synthetic materials.
According to Hannah, she was not modified against her will as is dismayingly common, but willingly accepted an even greater degree of augmentation than standard in her position.
Personality
Given the circumstances of her appearance on the news, one might be surprised to find Hannah a calm, even-tempered, and even empathetic person with a sense of justice. While reserved and stoic by nature, Hannah is often prone to bouts of restlessness, which she prefers to work through via intense exercise, sparring, or just finding super-criminals to fight. She's inclined to mask her feelings and refrain from letting people in, while actively reaching out to others to offer an ear or a shoulder. She can be found drinking on most nights, and may or may not be a functional alcoholic. Hannah can be reckless to a degree bordering on self-destructive in situations where she takes on most of the danger, possibly a psychological consequence of her durability and inability to feel pain; she also has a problem seeking help from others even when failing to do so will create problems.
She seems thoroughly accepting of her heavily modified state, even dressing to show off her chrome and deliberately eschewing means of appearing more human such as limb sheaths. Hannah has said this is a deliberate statement: She believes that if she truly accepts what she is, she should be fully comfortable with its display, even if it draws harassment and anti-transhumanist sentiment.
