A comparison of characterization, compatibility, and narrative function of the Robins within the Batman and greater DC universe.
The writer has five potential options to choose from, Dick Grayson a.k.a Nightwing, Jason Todd a.k.a Red Hood, Tim Drake a.k.a Red Robin, Stephanie Brown a.k.a Spoiler, and Damien Wayne.
Each served as Robin for an extended period and all contrast Batman in their own ways. The writer can present a case for and against each of them both from the text and metatexually such as referring to sales or fan receptions.
Good start. Rather than just "who's the best," however, consider going deeper and doing a full compare/contrast between the five incarnations. Consider the strengths and weaknesses of everyone, and when you choose an overall "winner," explain why their strengths rise above the others', while their weaknesses are less egregious or more humanizing/endearing. – Stephanie M.6 months ago
