Rebecca was a very sharp-tongued young woman, and has a tendency to be extreme and unpredictable. She was often shown going all out in fights, sometimes even laughing manically. Nevertheless, Rebecca is loyal and does everything for the crew of Maine. Rebecca has feelings for David Martinez. Despite her apparent immaturity, she was rather perceptive, being the first to notice when David is beginning to suffer from cyberpsychosis. She also handles her romantic interest in David maturely, never violating his boundaries beyond flirting.

Rebecca is short in stature, with soft features and stark white skin with a faint blue tint to contrast with the pink tattoos on her neck, stomach, and right thigh that reads "PK DICK". Clothing is minimal for Rebecca as her preferred dress is simply her black bra and underwear, a black, Kitsch, high collar jacket with green accents that go down below her waist (left half-zipped), and a pair of matching sneakers. Besides the jacket and shoes, she pulls her green hair up into pigtails with a dual clipped hair band. Her cyberware is subtle with only her pink and yellow cyberoptics standing out.

Rebecca was born in Night City, being the daughter of a notorious mercenary by the handle of Papa Sunrise, and the younger sister of Pilar. Becca's mother vanished when she was six, never to see her again. Anytime she asked about her to Papa Sunrise, he got mad, telling Becca off and admonishing her for being just like her mother: emotional, unpredictable and too compassionate. One day, however, her father also disappeared without a trace. His brother vowed to find the ones responsible for that, but first he had his little sister to take care of. The following years were really rough for Becca and Pilar. The two siblings had to live on the street, in Papa Sunrise's broken-down car. Pilar promised to Rebecca that he would get them off the street quickly, no matter what it took, with the idea of becoming a merc himself. Rebecca accompanied him while on the job with the intention of becoming a mercenary as well. It was not easy, especially since there was always something that hold them back from scoring big. Then Pilar realized the problem was his chaotic sister, who sank every mission they were hired for. Emotional, unpredictable and too compassionate were the traits that hold Becca back. Then Pilar introduced her to Maine and his merc crew. Ever since, both siblings teamed up with Maine to accomplish gigs, giving Becca the fame of a short, spunky, trigger-happy solo who was always fighting at her brother's side. Becca decided she would be the person to kill him one day instead of a random punk. In spite of everything, however, she cared about her brother.

”Becca, trip him up.”

The call from Maine was all she needed. Rebecca got up from her stool at the bar and walks next to Maxim with a smirk. She knew what to do. She “accidentally” spills booze over his suit. Obviously, Maxim wasn’t happy. He responded in cuss words and anger.

”Hey what the fuck?! You bitch-“

Rebecca says in a rather not so sincere tone:

“Oh I’m so clumsy!”

then. Sensually cleans the booze off him. Which, “tripped him up”. She knew exactly what she was doing. After, she’s sitting back on the stool and waving to Maxim as he left.

“Sorry about that, handsome!”

Maxim had a smile. Not from happiness but probably from being touched like that.

”Nah, it's no problem, sweetheart.”

“Make it up to you next time, K?”

She responds, still smiling as if she didn’t do a thing.

but then.

he noticed that his keys to his car was missing. He searched around his suit, his smile immediately gone. Then turned back to Rebecca and yelled at her.

”You bitch!”

“Why are you yelling at me? I'm sensitive, you know!”

she teased as Maxim ran out the door to the bar. She let out a self assured sigh, and drinks some booze. Even though she looks young she’s actually in her 20s. Now her job’s handled. All that’s left to deal with is the other guys getting the data from Maxim’s car for the gig.

until…
