Pillar was a tall male with black hair styled as a mohawk. He has golden robotic hands, and some sort of cybernetic goggles connected to a piece of cyberware that goes down beside his ears all the way to his chin, making him look like as if he has a beard. He is seen wearing a black sleeveless vest with a pair of jeans.

Born in Night City, Pilar grew up admiring his father, a notorious mercenary by the handle of Papa Sunrise. It was him who inspired and trained his son during Pilar's early years. The kid had a hard life, and it pained his dad to see it, but they stood together over the years. At some point, Pilar's parents had Rebecca, his much younger sister. However, Pilar's mother would vanish six years afterwards, with Papa Sunrise never wanting to talk about her. One day, however, Papa Sunrise also disappeared. To Pilar — his dad's biggest fan — it was a devastating loss, but he never thought he had abandoned them, rather that Papa had been killed, betrayed by someone. With such a fervent belief, Pilar pledged to find his murderers and execute them in a worse way than what they ever did his father. First, though, Pilar had his little sister to take care of. The following years were even worse for Becca and Pilar. The two siblings were forced live on the street, in Papa Sunrise's broken-down car. Pilar promised to his sister that he would get them off the street quickly, no matter what it took, with the idea of becoming a merc himself and show the city just how solid of an edgerunner he was. Unfortunately for him, most of his father's acquaintances simply turned their back on them, that is until they went to see Wakako Okada, chief among all of his dad's contacts. "Auntie" Wakako — as Pilar liked to call her — proved willing to help, giving the young merc a number of gigs and recommending him to other employers. It was rough, 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. Rebecca's compassion and zaniness built a rift between both siblings and their respective merc careers. Realizing he needed help to control her, Pilar eventually signed on with Maine and his mercenary crew. Thanks to this, the path to realizing his dream of becoming a Night City legend begun to be realized. Ever since, both siblings teamed up with Maine to acccomplish gigs, giving Pilar the fame of a comical and crude techie who was always fighting at his sister's side. Both siblings were always fighting with each other due to their conflicting personalities, making Becca decide she would be the person to kill him one day instead of a random punk.

Pilar, Rebecca's older brother, is a crude, foul-mouthed, and comical techie who serves as Maine's crew's tech specialist. He's characterized by his irreverent humor, explicit language, and controversial, sexually explicit interactions with other crew members, particularly Lucy. Despite his problematic behavior, he is also described as one of the most stable and social characters in the crew, though he dies in a particularly meaningless way. . . .

”Check out them precision chooms, fastest fingers in the west!”

Pilar was juggling plates and empty bottles in front of an audience, laughing. He wasn’t wrong though, he was good at it. His long arms really help. They’re long enough to reach his feet while he’s standing up. Dorio pipes in with a joke.

“Not the only thing I heard is fastest in the west.”

Dorio laughed as she made a jerking motion with her hand. Pilar noticed and threw the plates and bottles down, smashing them to pieces and standing hunched over.

“Spit it! The hell did you say?”
 but just as he looked upset, he turned the tables and laughed, also making a sexual hand thing with one remaining intact bottle. Of course everyone laughed, especially him with his manic laughter. The reason this party was happening was to celebrate after a gig they were successful at. Stealing the data from Maxim Kuznetsov's car.
