Oliver is what you would get if you were to mix a vain gentleman and a self-absorbed show-off together. Selfish and smug, he brags about his prowess in chemistry using buzzwords and pseudo-terms a real chemist would scoff at for being used incorrectly. Extremely out of touch with the fashion world, Oliver is good at pretending to care, listening, and gaining trust to exploit someone either subtly or directly depending on what he wants. Oliver is motivated by money, looking good in his boss' eyes, and the misfortunes of others.
Chemical engineering of the illegal sort, networking, feigning interest, doing cool-looking tricks with a butterfly knife without injuring himself too badly.
Oliver is terrible at fashion, and is unaware of the fact due to nobody ever pointing it out for some reason. Maybe one day he'll realise that top hats and canes went out of fashion a century ago. He does usually keep his long hair tied up in a man bun, not often seen under his ever-present tophat.
Oliver was not born into the best of families - his mother had tragically passed away after giving birth to him, and his father was involved with local street gangs. Him and his father lived in a crime-ridden suburban neighbourhood, where his father made a living from selling illicit substances. Oliver had an early exposure to the criminal underground at a young age due to his father sending him to inconspicuously deliver drugs to customers, making him deliver messages to other gang members, or having him help out in the production of illegal narcotics. This lifestyle caused Oliver to grow up desensitised to the darker aspects of human nature, and eventually caused him to start resenting authority after his father was arrested in a police drug raid.
After moving in with his indifferent aunt in the city proper, Oliver finished his public high school education at the age of 18 and did not go for tertiary education due to lack of money. Not being able to land himself a job through traditional means, he soon resorted to using less-than-legal approaches to getting hired. Using connections gained from his father, Oliver started his career off as a blue-collar worker and messenger for a local crime ring. One of his superiors eventually promoted him from a drug dealer to a drug manufacturer after recognising that he was good at handling chemicals, despite his brutish looks. The new job plus some of his father’s savings gave Oliver enough revenue to move out of his aunt’s residence into a small house, complete with an easily hidden basement and equipment to produce narcotics in secret. With this set up, he was able to manufacture the illegal products much more efficiently, eventually becoming known within a few certain underground circles as the go-to guy for buying drugs. As there was no more need to import drugs as much and thereby saving money for those in the crime ring, Oliver found himself somewhere in-between the middle and top tiers in terms of gang hierarchy - he had connections in more places, knew how things worked, and was good at his job. He considered himself well-off, raking in lots of cash and money.
Unfortunately for Oliver, demand for conventional illegal substances had dropped recently in the past few months due to competing gangs utilising the same tactics as theirs, reducing the revenue the crime ring was getting. Overabundance and large supply of the substances drove down demand. The responsibility of solving this problem was somehow delegated to him from his boss, which left Oliver searching tirelessly everyday for some sort of solution to dropping profits - perhaps introducing a new product to market would be the best solution, he thought... But where would one get such a drug? (Somehow transition Oliver to meeting Doctor Parker in a way that makes sense or something)
He may have bet on Aella once or twice during his brief underground gambling stint.
