chosen
Explanation
The Joke
The comic parodies the classic fantasy trope of "The Chosen One." A group of medieval adventurers debate among themselves about who the prophecy's chosen one really is. One bearded warrior insists the boy is the chosen one because he was given to them by the Green Dragon. Another objects, pointing out the boy is an "unmarked nobody" who has no place in their society and was only "chosen" through arbitrary circumstance. The boy's supporters dismiss these concerns.
The scene then cuts to the boy confronting a dragon, declaring "Face me, dragon! I am the chosen one!" The dragon promptly eats him with a decisive "chomp." The dragon then asks the remaining adventurers who among them speaks for the boy. When the bearded warrior replies "Uh, all of us," the dragon announces it will leave their land in peace for all time. The group cheers -- they got what they wanted, and the "chosen one" was essentially just a disposable sacrifice.
The Humor
The comic skewers the Chosen One trope by revealing the uncomfortable logical endpoint that fantasy stories usually gloss over: if someone is "chosen" by prophecy to face a terrible monster, what that often really means is that they are being selected to die so everyone else does not have to. The adventurers' willingness to send an unmarked, unremarkable boy to his death, and their cheerful acceptance of the outcome, exposes the cynicism lurking beneath heroic narratives about destiny. The dragon's businesslike negotiation adds to the comedy -- it treats the whole thing as a simple transaction rather than an epic confrontation, which further deflates the grandiosity of the Chosen One mythology.
References
The comic references the ubiquitous "Chosen One" trope found throughout fantasy literature and film, from Tolkien's hobbits to Harry Potter to countless video game protagonists. The trope is a staple of the hero's journey narrative structure as described by Joseph Campbell.
