Dr. Jekyll and Mr. Hyde Meet Their Match

This is a short story I did for a local fanfiction contest (I won!), using characters from the story "The Strange Case of Dr. Jekyll and Mr. Hyde" by Robert Louis Stevenson. It would help if you've already read that, but if not, perhaps you'll still find some entertainment in this. It features a bunch of characters from the novel, as well as a few I made up.

While I was writing this, I envisioned it as an old black and white horror movie, and that's how it plays out in my mind when I read it.
