Final answer:
Mufasa should invent a fictional name to refer to his boss in the novel to protect himself from libel.
Step-by-step explanation:
The primary thing Mufasa needs to do to implement his editor's suggested strategy is to invent a fictional name by which to refer to his boss in the novel. By using a fictional name, Mufasa can create a character based on his real boss while still protecting himself from potential libel claims. This method, often used by writers like Hemingway and Plath, allows Mufasa to draw inspiration from his experiences without directly naming or identifying his boss.
