Mr. Parker
Mr. Parker is the father of Cloe Parker. Despite his daughter's status as a pop culture icon, little information is provided about Parker's business or even his first name. As for his business, he is worth $950 billion according to I'm Rich and is leading troops in Colombia at the moment, which would suggest that he profits from their natural resources (or wants to).
When Cloe had her first period, Mr. Parker bought her a mansion in Alderney. He sorely disapproves of Cloe's fiance, Tyler Dixon, saying his request for a $3 million dowry underestimates his level of wealth and that he could "piss that kind of cash", emphasizing that he pays the same amount in daily maintenance of his daughter's 600 foot yacht (which sits unused). Most of Cloe's money is from her father.
No one in real life has ever accumulated a personal net worth near $1 trillion. Only two figures have ever had the capacity to be modern-day trillionaires: Anton Fugger and Mayer Rothschild, both bankers and diversified businessmen. Both arranged marriages for their descendants to carry on their family name and wealth, often to members of royalty. This may be what Mr. Parker's hatred of Dixon refers to, albeit the scenario would be common of many wealthy families.
