I am rarely one to be pulled in by fanfiction. Such a rare occasion has now occurred in the form of the on-going web-comic
A Tale of Two Rulers. Its premise: Zelda asks Ganondorf to marry her. The premise is blasphemous, ridiculous and insane but it pulls off that fanfiction trick of actually making you believe it works.
The first 67 pages were voice dubbed three years ago and compiled into the following video.
The focus is more on the emotional journey, the precariousness of the setup and the comedic interactions of the characters. Don't expect focus on governing policies and the state of Hyrule etc. The comic does a great job at pulling from official Zelda lore and making use of many characters from different titles while putting them in this more gritty version of the Zelda universe. The main premise alone definitely has a fetish element to it (both "beauty tames the beast" type of stories and Ganondorf definitely has their thirsty fans) but thankfully the comic focuses on mid-brow and high-brow content instead of descending into fetishisms.
There are currently about 209 pages of this webcomic,
most of which can be read on tumblr and the remainder
can be found on patreon.
