Final answer:
Ratso Rizzo from Midnight Cowboy may serve as an example of a resilient, marginalized character who appeals to a wide audience through credible characterization, similar to other literary examples that show indomitable spirit and enduring impact.
Step-by-step explanation:
Ratso Rizzo, the character that Dustin Hoffman plays in Midnight Cowboy, is often used in literary discussions as an example of a character that illustrates the theme of the underdog or marginalized individual struggling against societal norms and challenges. In the context of the question, it is unclear what specific example the character is used for without additional text. However, if we refer to the examples provided in the reference information, Ratso Rizzo might be an example of a powerful character who, despite his circumstances, impacts the audience through credible characterization and enduring appeal. Similar to the bear in the second LibreTexts example provided, Ratso could be an emotionally accessible character that appeals to a wide audience. Like Phoenix Jackson's determination and spirit in Eudora Welty's A Worn Path, Ratso's character could illustrate resilience and the human condition.
