Since I don't know the specific 'worm dragon fanfic', it's hard to say. But it could be the worm dragon itself as a main character. There might also be a brave adventurer or a curious scientist who is trying to understand or interact with the worm dragon.

The main characters in 'cape and cowl worm fanfic' often include the traditional caped and cowled figures we know from superhero stories. However, there are also new characters introduced specifically for the worm - related plot.

And of course, the classic superhero characters like Superman - like or Batman - like figures who are always there to uphold justice and fight against the threats posed by the worm and its related phenomena.
