Rocky is an Android manufactured by United Robotics and the owner of the Ox & Carriage, a pub in Titan Garden's A-District popular with port workers and travelers. Despite his imposing figure, Rocky is very soft-spoken and friendly, sparing a few words of his own but happy to quietly listen to pubgoers tell their tales and share their troubles. Rocky has overridden safety protocols and is able to serve drinks to people who are about to have a bit more than they can handle, which is a logical pursuit for him as people in that state make for bigger stories, either embellishing them or creating them through their actions. The Ox & Carriage has rooms on the second floor to put people if they go too far over the line, and Rocky being a seven-foot-tall United Android means he never personally feels endangered, he can simply pick a patron up and deliver them to their room for the night. They'll wake up sober and find a fun new expense on their tab, which works out just fine for Rocky as well.
The United Robotics Corporation designs their Android lines for heavy industries, and Rocky was made for deep space mining operations. His chassis and armor paneling have rounded hemispheres to help deflect the impact of falling rocks and he has four optic sensors to allow him to see in dark caves, with one top-mounted optic on his helmet so he can clamp his head down behind his head unit's protective collar and still see what he's doing. Contrasting a construction unit like Buck, Rocky's hands are smaller and more dexterous, designed to operate the controls of even larger heavy mining equipment. Like many United models Rocky's feet have retracting stabilizers on either side to allow improved footing across uneven terrain. As a personal modification Rocky has seen fit to add little clips to his chassis so he can pin an apron to his lap and fulfill his role as bartender in his pub.
Androids are synthetic sentient lifeforms, and as such they cannot be compelled to work at any specific job. Androids are built with specific tools to enable them to perform a given task well but they are free lifeforms who are hired onto jobs, not sold as tools- hiring a specialist Android is generally always a good idea so they rarely have problem finding work in their designated fields. Rocky used to work with a few deep space mining outfits, digging water wells for colonies or braving the asteroid belt for mineral extraction before he quit and chose to become a pub owner on Titan. Rumor has it Rocky and his old crew have met the mythical Devil's Fang Pirates out in the Asteroid Belt, and Rocky has personally shook hands with their captain. Other people tend to tell this story for him, he won't speak a word of it himself, not to confirm nor to deny. He'll just stand quietly and clean a glass.
Stories are the whole reason Rocky chose to leave mining and open a pub. He was built for life underground and he enjoyed his work, but he found the most enjoyable part of the job was hearing other miners talk, hearing them bust each other's chops or spin impossible tales and seeing other miners try to rationalize them or dismiss them incredulously, which would get the storyteller to try to back up their claims with even bigger claims. Rocky observed that organic teammates would tell more interesting stories and get into more entertaining trouble the more alcohol they have imbibed, so logic dictates that he can encounter the aspects of his mining work he liked the most by running a place for organics to congregate after a hard day's work and feeding them copious amounts of alcohol. And so he took his leave of deep space mining and opened the Ox & Carriage in the exact right place to get as many roughnecks and rogues as possible together, right in Titan Garden's A-District, in walking distance of the starports. So if you're ever on Titan be sure to stop by, share a tale of your travels and don't be afraid to order just one more drink. The worst that'll happen, you'll wake up in the upstairs lodging the next day with a headache, a new scar and a brand new story to tell, assuming you can get that story from the people who saw it unfold. You probably won't remember very much of it yourself.
