Ferdinand is the future heir of the legal and illegal business of the Rhodes family and he is very much living up to his father’s expectations

his parents' relationship is largely based on money, reputation and convenience with his submissive mother being a socialite and his dominant father being a workaholic and a cheater. A fact that his mother covers up, compensating the form of humiliation with shopping tours and even more champagne

Ferdinand and his twin sister are thick as thieves, her being the only human being that knows all of him. The bad, the ugly and even the good parts (that he is an expert hiding)

He has probably been more of a father to his siblings than their actual parents, including regular lectures about them sneaking out for parties and enforcing rules 

The security system in the Rhodes mansion is state of the art, including a rather large staff of bodyguards that are assigned to the members of the clan at any given point

The Rhodes children have been growing up with dogs all their lives and the current family dog is an Akita Inu that they got as a puppy and who stayed with the family for almost 8 years now

Ferdinand started owning and training different types of guard dogs at the age of 16 (including German Sheperd, Malinois, Doberman, Rottweiler and later Cane Corso which he stuck with ultimately). All of the guard dogs that are currently protecting the Rhodes family members including the property have been bred, chosen and trained by Ferdinand and/or the head of security.

He has two dogs that he keeps by his side at all times, called Mars and Pluto  

Ferdinand knows how to use a gun, has a concealed carry permit and he will not hesitate to use it if necessary

Ferdinand's motto could be broke down with "Si vis pacem, para bellum" and the other would be "No one hurts my family and lives"
