Jonathan Caesar was the owner and resident of the spacious Manhattan apartment building Bedford Towers, in which Peter Parker and his wife Mary Jane Watson came to live.
However, this was no accident, as Caesar was obsessively in love with the famous model Mary Jane, and had arranged it so she would move in to the building he owned and lived in. Caesar kidnapped Mary Jane and imprisoned her in a reinforced room inside Bedford Towers itself. Caesar hired Styx and Stone to oppose anyone who tried to investigate, such as Spider-Man, who was secretly Mary Jane's husband Peter.
