Marlon Bundo is the real-life name of Mike Pence's (the former Vice President of the United States) family rabbit. The name itself is a reference to famed American actor Marlon Brando. A semi-fictionalized version of the male bunny has been the protagonist of two children's books, each coming out in early 2018. The first released one depicts Marlon falling in love with another boy rabbit (a brown bunny named Wesley) and getting married.
